Bang! Cart for Stripe gives every product a buy button you place exactly where you want it - any page, any post, with a shortcode. Customers fill a fast, polished basket that matches your theme, and pay on Stripe's own checkout page. Your pages stay yours: the plugin adds no pages, no templates and no database tables of its own. Stripe holds the card details and the order history - this plugin never sees a card number and keeps no order records of its own. What it does

Add-to-basket buttons for your Stripe products, or for products you add here.
A basket that works on a phone, in your theme, with your fonts and colours.
Delivery zones of your chosen countries - as many zones as you need, each with a flat rate per service, or first item plus each additional - with collection in person.
Free postage over a spend or a number of items.
A shop-wide sale percentage.
Discount codes, fixed or percentage, with a use limit and an expiry.
Stock counts, with low-stock and sold-out messages you write yourself.
Reservations, so two people cannot buy the same last item.
Confirmation emails to your customer and to you, in your own words.
A PDF receipt the plugin makes itself, attached to both order emails - switch it on under Invoice / receipt document (Settings, Emails tab) (a fresh install sends no document until you choose one).
Delayed bank payments handled properly - stock is not released while a Bacs payment settles.
Your business address and a cancellation and returns notice in the order emails, as UK and EU law asks.
A thank-you page made for you in one click, and an order status page your customer reaches from their email - no account or password.
Orders in your WordPress admin, newest first, with Mark posted (or Mark collected) - also from a button in your own order email - and your takings all time. Only orders taken through Bang! Cart are listed, never payment links or other sites on the same Stripe account.
Bold, italic, links and lists in product descriptions, and shortcodes for a product's price or description anywhere on a page, so pages never show an old price.
A Start here page that checks, every time you open it, everything a customer needs to pay - your Stripe key, the connection, products on sale and why any are not, buy buttons on your pages, postage and emails - with a button to the exact spot that needs fixing, and a Going live checklist.

How your customers can pay Checkout happens on Stripe's own payment page, so your shop offers whatever payment methods your Stripe account has switched on - cards, Apple Pay, Google Pay and Link out of the box, and methods like Klarna, iDEAL, Bancontact or Bacs Direct Debit where your country and your customer's support them. Strong Customer Authentication (3-D Secure) is handled there too, automatically. None of it is configured in this plugin: you switch methods on in Stripe, and your checkout follows. Stripe ships new payment methods, and your shop simply has them. What it deliberately does not do

It does not store card details. Payment happens on Stripe's page.
It does not keep a copy of your orders. Stripe already has them, and one truth beats two.
It does not do subscriptions, tax tables, or a hundred payment gateways.

Who it suits Makers, artists, food producers, small-batch and craft shops - anyone selling a focused range of products from a site that is more than just a shop. If your products live on pages you designed, and you want a buy button on each and a shopping cart that follows your customer around the site, this is built for you. You will need A Stripe account and a restricted Stripe key, which the plugin helps you create in one click. Test mode works exactly like live mode, so you can try the whole thing before taking a real payment. Documentation, with screenshots of every step, lives at bangplugins.com/docs/cart. Bang! Cart Pro Everything above is free, for good. When your shop needs more, the Pro add-on plugs into it - same settings, same pages, nothing to move:

Sizes and colours - one product in several options, each with its own price, stock and photo.
Checkout on your own site, with Stripe's payment form inside your page.
Digital downloads - sell a file beside the things you post.
A product grid and single product cards for any page.
Quantity discounts, order value discounts and "buy these, get that free" gift offers.
Postage priced by number of items or by order value.
Back-in-stock emails, for a sold-out product or a sold-out size.
Gift options with a message and paid gift wrapping, customer notes such as a name to engrave, and prices the customer sets, for deposits, donations and gift vouchers.
Reports - takings, best sellers down to the size and colour, discounts and refunds, with charts and CSV downloads.

3.9.1

Fix: with Bang! Cart Pro's checkout on your own site, a shop whose Stripe account was set to an API version older than March 2026 could not take payments - Stripe refused every checkout with "Invalid ui_mode: embedded_page" and the page stayed on its loading boxes. The plugin now tells Stripe which version that checkout needs, so the age of the account no longer matters and nothing needs changing in Stripe. Checkout on Stripe's own page is unchanged.

3.9.0

New: each product on the Products page has one Copy shortcode menu in place of the separate copy buttons. It lists the Add to basket button, the price and the description, each with a small picture and a line saying what it gives, so the header stays tidy and it is clear which shortcode does what. The price is left out for a product where the customer types the amount, as before. With Bang! Cart Pro the menu also offers a product card.
New: a little formatting in product descriptions. Four small buttons above the description box make the words you select bold, italic or a link, or turn lines into a bulleted list, and line breaks are kept. Only those are allowed - anything else, scripts and styles included, is removed when you save - so one product can never upset the rest of your page. Stripe's checkout page shows the description as plain text, with no tags. A Sync from Stripe now keeps the line breaks in a Stripe description too.
New: the Products page opens with "Which way should you add a product?" - made in Stripe and synced, or made here in Bang! Cart, side by side, with what each is best for and what to know. It folds to one slim line with a click and stays folded for you (each admin's choice is their own); on a new shop it starts open. The long paragraphs under Stripe products and Other products are now one line each.
New: [bangcart_description id="..."] shows a product's description on any page, with its formatting, in the page's own font - change the words on the Products page and every page follows. Copy it from the product's Copy shortcode menu (Description on its own). A product with no description shows nothing to customers.
When a shortcode is copied from a product's Copy shortcode menu, the button turns soft green with a tick for a moment, so it is clear the copy worked.
The click-to-copy chips - shortcodes in the help text and the email tokens like {order} - turn the same soft green when they say Copied!, in place of the accent colour.
Send test emails on the Emails tab now sends in the background, like Bang! Cart Pro's back-in-stock test. The page does not reload and nothing on the tab is saved - both emails are built from what is in the boxes now, saved or not - and a message beside the button says where they went, or why they could not be sent. A typed test address is still remembered for next time.
The message after Send test emails sits on its own line under the button: a soft green panel with a tick when they went, red with a warning when they could not be sent, and a spinner while sending.
The email previews at the top of the Emails tab follow your wording as you type - greeting, message, footers and the cancellation block - not only after Save. They are still built by the same code that sends the emails, so what you see is what goes out.
"Emails not arriving?" now sits at the top of the Email delivery log, where you look when an email goes missing, instead of in a card further down; the similar line under the log has gone. The Webhook & connection card, which only pointed to the Stripe tab, is gone from the Emails tab - the connection lives on the Stripe tab.
Tick boxes and radio buttons in Bang! Cart's settings are the plugin's own blue, whatever WordPress admin colour scheme you use, so they match the rest of the plugin.
Every shortcode you copy from the admin sits in the same box: the code in dark text on light grey, with the Copy button the same height beside it. That covers the thank-you page, sale banner and basket shortcodes, the webhook link, and Bang! Cart Pro's checkout page and product grid shortcodes. They used to look different on each tab, and most showed the code so pale it looked empty.
Every Copy button now says Copied! in the same soft green with a tick: the shortcode boxes on the Settings and Discounts tabs, the basket shortcode on the Design tab and the webhook link on the Stripe tab. If the browser refuses the clipboard, they fall back to the older way of copying instead of doing nothing.
The product card on the Products page is calmer. Its details, its words and photo, and its options are set apart with more room and a faint line instead of boxes. The description's formatting buttons sit inside the top of the box like a small editor, with a one-line hint. The photo is a small preview beside the description, with Choose (or Change) photo and Remove. Options stay closed until you open them, on every product; the bar shows only the options in use. Opened, they are one list with no box around each, and an option's settings sit under its own name.
Calmer wording in three places. Emails: the Cancellation and returns block says what the law wants in one line, with the advice for shops outside the UK in a fold, and its box starts shorter. Stripe: the key card says why to switch to a restricted key in one line, puts one button and one sentence in place of four steps, and sets the test and live boxes side by side. Design: the basket shortcode sits under "I'll place it myself", with one line of help.
The Orders page opens with your all-time takings in a banner of their own, in the plugin's blue with white text that meets accessibility contrast rules, with orders all time and how many are to go out beside them. The orders card below shows Test or Live mode beside its heading, with one line of help.
Preview your pages on the Design tab: the same six previews, sorted into a row per page with equal buttons, and the thank-you note now points to the General tab under Settings, where that page is chosen.
The "One discount per order" box on the Discounts tab stays first, as before, but now says the rule in one sentence, with "How it decides, with an example" folding open for the detail.
The "Stripe refused to create invoices" warning on the Emails tab now uses the plugin's own amber note, like every other warning.
The Duplicate button on each product is now the same size as the Copy shortcode button beside it.
Fix: a product's description box no longer runs past the right-hand edge of its card.
Fix: in a delivery zone priced by order value, postage is now worked out on the things that are actually posted. Something that needs no delivery - a deposit, a balance, a file to download - used to count toward the postage band, so a £20 item beside a £5.50 jar could push the jar into a dearer band. The free-postage threshold still counts the whole order, because that is a reward for spending. Shops that post everything see no change at all.
Groundwork for Pro digital downloads. A product can be marked as a download: it is never posted, and on the free plugin alone it is not sold - this plugin cannot deliver a file, so it does not take money for one. The mark survives any save of the Products page. With Bang! Cart Pro it sells the file, with a private download link for each buyer.
Groundwork for add-on options on products synced from Stripe, an item in each order's menu on the Orders page and a line under each order's items, a per-product "one per order" limit in the basket, and a place on the Emails tab for an add-on's own email settings. All invisible on the free plugin alone.
Uninstalling the plugin now also removes any files a shop sold as downloads with Bang! Cart Pro, so nothing paid-for is left on the server once both plugins are gone. It also clears each admin's folded or open choice for the Products page's opening card.
New: Start here has a "Ready to take payments?" card. It checks everything a customer needs to get from your page to a paid order, every time you open the tab: your Stripe key, the webhook, the shop being open, products that can be bought (and why any can't), buy buttons found on your pages, the basket when you place it yourself, postage, order emails, the thank-you page and your business address. Amber stops a sale, grey is worth doing, green is ready, each with a button to the tab that fixes it. The page scan reads page content of any post type, Elementor, Beaver Builder, Bricks and Oxygen data, and widgets.
Start here's buttons take you to the exact spot on the page - the field, section or product that needs attention - highlight it for a moment and put the cursor in it. A product that isn't on sale opens, with the option that stops it open too.
New: a "Going live" card on Start here while you are in test mode - your live key, the live connection, switching to live mode, and a first real payment, ticked as each is done.
New: when something stops customers paying, Start here in the WordPress sidebar shows the count in amber, and a short amber bar at the top of every other Bang! Cart page names the problem, with a button to Start here. Both go by themselves once it is fixed. The Orders count stays blue.
New: Bang! Cart has its own items in the WordPress sidebar - Start here, Orders, Products and Settings (and Reports with Bang! Cart Pro) - in place of one row of tabs. Settings keeps a row of tabs for General, Discounts, Shipping, Emails, Design and Stripe. Every page except Orders has its "On this page" menu down the left from about 900px wide, and wide tables turn into cards when that leaves them too little room. Every old link still works.
New: a short "What's new" walk-through the first time you open Bang! Cart after updating - what moved and what is new, one slide at a time with arrows, ending on Got it. Each admin sees it once. A new install gets the same walk-through as a welcome, worded for a first look.
Orders: the list and the takings banner count only orders taken through Bang! Cart on this site. A payment link, an invoice, another plugin or another website on the same Stripe account no longer shows up. Orders from now on are stamped with the site they came from; older ones are recognised by Bang! Cart's own return address. If your shop has moved domain, orders taken before the move on the old address are no longer counted.
Orders: orders still to go out are a blue notice above the list with a "Show only these" button, and a checkout Stripe refused is a red one with the details folded away. The page has no side menu.
Every new order records each line, how many and what was paid for it, and the discount used, for Bang! Cart Pro's Reports.
Fix: after opening a closed shop, "the shop is closed" no longer stays at the top of the page you saved from. Notices that read a setting you have just saved (shop closed, currency, delivery zones, the webhook and site-address reminders) now wait for the save, so they describe the new setting.
New: a product that isn't on sale says why. Point at its NOT ON SALE badge for the reason; open the card and the option that causes it turns amber in the bar ("Not on sale - see Variants") and says what is wrong at the top - in the same words as Start here.
The Options bar on each product is now called "Product type and extras", and while nothing in it is in use, a grey line lists what it holds - so variants, downloads and the rest are easy to find.
Groundwork for Pro free gift offers: a basket can carry a free gift line at no charge - shown in the basket with a nudge when it is one product short, sent to Stripe as "(free gift)" at 0, held and taken from stock with the order, and never counted as goods, units or postage. If an older Stripe account refuses a line at 0, the order goes through without it and still names the gift.
No more WordPress-blue focus rings anywhere in the plugin. Clicking a tab, link or button leaves nothing behind; moving through the page with the keyboard shows a soft halo in the plugin's own blue, and a field you are typing in keeps a plugin-blue edge.
Secondary buttons - Sync from Stripe, Send test emails, the CSV downloads and the rest - are now navy with white text, a lighter navy under the pointer, so they show on the grey page as well as in white cards. They were a pale purple that turned blue on hover.
Order emails go only to orders taken through Bang! Cart on this site. Stripe tells your site about every checkout on the account, so a payment link or another website on the same Stripe account used to get your shop's order confirmation and a seller copy; now it is noted in the connection log and nothing is sent.
Groundwork for add-ons: an add-on can ask for more webhook events, and a webhook the plugin set up is brought up to date with them by itself; refunds are passed to add-ons. (Bang! Cart Pro uses it to stop a refunded order's download link.)
The number beside Start here also counts the grey "worth doing" rows, and turns grey itself once nothing amber is left, so an untested email address or a missing business address is not forgotten. The numbers beside Start here and Orders in the WordPress sidebar keep their colours on the page you are on and under the pointer, and change as soon as a save changes them, instead of on the next page load.
New: your shop in the visitor's language. On a site running WPML or Polylang, everything you typed that a customer reads - product names and descriptions, button labels, the basket heading, postage zone and service names, collection and over-limit notes, the sale banner, the closed-shop message - appears in that plugin's translation screen under "Bang! Cart"; translate it there and the buttons, basket, its prices and Stripe's checkout show the visitor's language. Nothing to switch on.
New: you choose what Delete does. On the General tab, "If Bang! Cart is deleted" is Keep my data (the shop stays in the database for a reinstall) or Remove everything (settings and data erased, customers' names and emails included). Until chosen, Delete keeps your data; deactivating always keeps everything. One choice covers Bang! Cart Pro. Start here lists it under worth doing.
Orders: a posted order shows a green "Posted" label with a small Undo button beside it, always on show, instead of a grey button that un-marked on a single click; its menu button is green to match. Every fold in the admin now points down when closed and up when open.
Start here's "Buy buttons" row names anything that is not a page with its kind - "(Elementor template)", "(post)", "(block pattern)" - so a button found in a saved template is not mistaken for a missing page.
Fix: pressing Discard on the unsaved-changes bar no longer brings up the browser's "Leave site? Changes you made may not be saved" question - the changes were just thrown away on purpose.
Design tab: the Preview your pages buttons are all one width, so the rows line up.
Fix: with Pro's checkout on your own site, the visitor's language now reaches Stripe, so the payment form and its line items are in the language of the page they came from, as the hosted checkout already did.
Fix: on a Polylang or WPML site, the page dropdowns on the Settings tab (thank-you page, policy pages, and Pro's checkout page) list pages in every language and always include the page already chosen. With the admin bar filtering by another language the chosen page was missing from the list, and saving anything else on the tab quietly unset it.
The basket's "not yet". A download's tick box left unticked, or a note the shop insists on left blank, no longer shows as a red error with a total of "-" the moment the item lands. The total shows, Checkout is greyed, and pressing it anyway says what is needed, just above the button. Add-ons use the new bangcart_basket_wait filter for this; the checkout itself still refuses, so nothing can be skipped.
Orders with nothing to post - a download on its own, a deposit - are no longer "to go out". The row says Nothing to post in place of the address and the Mark posted button, and it is left out of the count on the banner, the sidebar and Start here. An add-on can say otherwise with the bangcart_order_nothing_to_post filter.
Fix: an order with nothing to post - a download on its own - no longer shows a Delivery heading over the customer's bare name on the thank-you page, nor SHIP TO in the order emails.
Fix: the owner-only note on a hidden button uses the Products page's own words - "not on sale: variants are switched on, but none has a price" - instead of reporting that the add-on is not active while Pro is running.
You are emailed when Stripe refuses a checkout. The customer has always been told "the shop has been notified of the fault"; until now that meant a card on the Orders tab you would see only by opening it. The email goes to the address your order emails go to (or the site admin), says when, in which mode, what Stripe said with its error code and parameter, and links to the Orders tab - no customer details. One email per distinct fault an hour, however many customers meet it, and a mail that cannot be sent changes nothing for the customer. With Pro, a payment form that could not load in a customer's browser sends the same.
A key Stripe rejects is named as the problem: the Stripe tab's green box turns amber ("Stripe doesn't accept this live key", with the key's last four characters and the paste box open), Start here shows an amber row for it, and the saved-key lines everywhere say which key they mean by its ending. Both keys are checked, not only the one for the mode you are in, so a live key Stripe does not know is caught while you are still testing.
The Pro tab lists everything Pro does: gift options, back-in-stock emails, digital downloads, free gift offers and Reports join the seven it already described.
The "Which way should you add a product?" card is lighter: each route is a one-line pitch and three ticks, in its own colour - Stripe purple for synced, Bang! Cart blue for made here - with the caveats behind a Good to know fold.
Review fixes before release: the keyboard focus ring shows on the navy and blue buttons too; "Show only these" keeps the hidden orders hidden on a phone; a page builder's autosave no longer drops the Start here scan, and Start here keeps that scan for two minutes so a big site is not searched on every reload; the sidebar's orders count stays put when Stripe cannot be read and goes up by one when the webhook fulfils an order; the What's new walk-through counts a shop with only a live key or a placed button as an existing shop, and is no longer shown ninety days on; a refund that arrives while the shop is in the other mode waits for Stripe's retry, like a fulfilment, instead of being dropped; a free gift is never held against stock before Stripe, so another checkout holding the gift's last unit cannot refuse the sale; a discount Stripe refuses at the session is retried with the collection line still on the order; a wrong coupon code typed into the basket counts against the same fifteen tries as the coupon box; orders on a site whose address has capitals are recognised as this site's; and an add-on that hands Start here or the Documentation button something odd cannot break the page.

3.8.0

Groundwork for the Pro product grid, plus the [bangcart_products] shortcode. On the free plugin alone it does nothing visible - the shortcode shows customers nothing and tells an administrator it needs Pro - so there is no reason to hold back the update. With Bang! Cart Pro it shows your products on any page as a grid or a list, each with an Add to basket button.
Groundwork for Pro gift options: a seam that lets an add-on put one flat, order-level charge (gift wrapping) on the basket - added after the goods, the discount and the postage, so it is never discounted and never tips a free-delivery threshold, and billed as its own line so the basket and the Stripe charge cannot drift. Invisible on the free plugin alone; with Bang! Cart Pro it powers paid gift wrapping in the basket.
New: the basket's heading ("Your basket") is now editable. Set it under Button labels on the Design tab - call it "Your bag", "Our larder", whatever suits your shop. The live preview shows it as you type.
New: the Add to basket button's text size is now adjustable, next to its colour and corner radius on the Design tab (11-28px). The live preview updates as you drag.
New: a Pro tab and a "Go Pro" menu link, so you can see everything Bang! Cart Pro adds from inside the plugin. Once Pro is installed the menu simply reads "Bang! Cart Pro" and the tab and link step aside - no selling to someone who already has it.
New: the basket's "Discount code?" button now only appears when you have a live code for a customer to type. Save your first code and it shows; when the last one expires or is deleted it quietly goes. No setting to manage - it follows your codes.
When saving codes flips that button on or off, a dialog reminds you to clear any page cache, since a cached basket keeps showing the old state until you do.
The Settings tab now runs in a sensible order: Shop status first, then Shop basics and the thank-you page, with policy pages at the bottom.
New: a quiet, dismissible prompt to leave a WordPress.org review. It only appears once your shop has taken a sale and a week has passed, never before, and it goes for good once you review or say you already have.
Sync from Stripe now says why products did not come in. If Stripe sends back nothing, it tells you to check the key comes from the same sandbox or live account as your products. If Stripe sends products the shop cannot use, it counts each reason: no default price, no fixed amount, a different currency, or a subscription. A sync that brings some in also lists what it skipped.
The Stripe products card now says a synced product sells at one fixed price, its default price in Stripe.
Fix: an admin-only shortcode note no longer duplicates itself where a theme or builder runs shortcodes twice.
Fix: a variants product with no priced variant could show the custom-price "not on sale" note, which named the wrong option.
Fix: a Stripe product with no description no longer causes a PHP warning on the Products tab.
Housekeeping: the connection probe no longer trips a Plugin Check warning about a non-prefixed filter, and the readme's changelog is trimmed to the recent releases (the full history ships in changelog.txt).
