Markup by Attribute for WooCommerce

Varying Prices on Product Variations is Tedious and Error-Prone Want to add $5 to every blue product you sell? Maybe you sell jewelry with birthstones, and some stones cost more than others. If all "X-Large" products cost 7.5% more, you'd have to manually calculate and change every "X-Large" variation of every product. Markup by Attribute Adds 'Markup' to Attribute Terms Markup by Attribute solves this by letting you add a markup (or markdown) to global attribute terms. If the attribute is 'Color,' you can add "+5" to Blue while leaving Green and Yellow alone. When you set regular and sale prices, every blue product will automatically be $5.00 more. This plugin does one thing - it adds pricing control to WooCommerce's global product attributes. If your products vary in price based on options like size, color, or material, Markup by Attribute lets you set those price differences once at the attribute level rather than manually adjusting each product variation. Key Features

• Fixed value markups (like $5) or percentage markups (like 5%)
• Positive markups for price increases, negative for decreases
• Integrates with WooCommerce's existing 'Set regular price' and 'Set sale price' bulk actions
• Shows price differences in the dropdown options to help customers make informed decisions
• Provides itemized price breakdowns in variation descriptions
• Quick bulk update tools to reapply markups when values change
• Support for both regular and sale prices
• Option to show or hide markup details in various places

Use Cases

• Size-based pricing: Charge more for larger sizes, less for smaller sizes
• Material upgrades: Add costs for premium materials
• Add-on services: Pricing for monogramming, gift wrapping, etc.
• Attribute-driven costs: Any situation where product options consistently affect pricing

New in Version 4.8

• The product edit screen now warns when a global attribute set to "Any" on a variation carries markups — customers see the markup in the options drop-down, but the "Any" variation's price never includes it
• Informational only: nothing is blocked, and a deliberate configuration is left exactly as you set it

Using Markup by Attribute for WooCommerce (Detailed instructions can be found at Markup by Attribute Wiki.) NOTE: These instructions assume you are familiar with WooCommerce global Product Attributes and with WooCommerce Product Variations. If not, you may want to review the WooCommerce documentation on Product Attributes and Variable Products. Three Easy Steps

1. While creating new global attribute terms or editing existing ones, add the markup.
2. If the option needs a markup, put the amount of the markup in the term’s Markup field on either the Add new attribute panel or the Edit attribute panel.
3. Examples of valid values include: ‘-5’, ‘5.95’, ‘+5.678’, ‘7.5%’, and ‘-12%’.
4. Create product variations as you normally would.
5. Markup by Attribute requires variable products because it changes the price of each variation.
6. Using Create variations from all attributes is the easiest way to ensure you have all combinations.
7. Do not have a variation with “Any” in an attribute with a markup because WooCommerce will choose the “Any” variation regardless of others that may exist. So, if XX-Large is 5% more, you cannot have one variation for “XX-Large” and another for “Any size” to cover the rest because WooCommerce assumes “Any size” includes “XX-Large”.
8. Use the Set regular price and Set sale price bulk edit functions as you normally would.
9. The markup will be applied to the price according to the attribute terms associated with the variation.
10. A description of the markup will be added to the variation description. Product Price 18.95 Add 2.00 for Logo
11. TIP: Always set the regular price before setting a sale price. Percentage markups are calculated on the regular price, so they cannot be applied to a sale price if the regular price has not been set.
12. TIP: If you change a markup value later, you can quickly update affected products using:
13. The "Reapply markups" bulk action on the Products list
14. The refresh icon beneath the attributes of individual products in the list
15. The "Reapply markups to prices" option in the product's variation bulk actions

4.8.0 Release Date: September 2026 Added

• A "Reapply attribute settings" bulk action on the attribute term list. Turning "Add Markup to Name?" or "Add Markup to Description?" on or off used to affect a term only the next time that term was saved, so changing your mind meant opening every term in the attribute and saving it one at a time. Select the terms and apply the action instead. Names and descriptions are all it rewrites — prices are untouched until you reprice or reapply markups
• The attribute term list now warns when its terms no longer match the attribute's settings, saying how many are affected and which setting they disagree with. The name and the description are reported separately, because they can disagree in opposite directions at the same time. The warning clears itself once the terms are back in line
• The product edit screen now warns when a global attribute carrying markups is left as "Any" on a variation. WooCommerce offers every one of that attribute's options in the drop-down, markup and all, but prices the "Any" variation — so the markup is shown to the customer and never applied. Where the markup is negative, the customer is charged more than the drop-down promised. The notice lists the affected attributes and sits above the variations [Bulk actions] menu. It is informational only: nothing is blocked, and a deliberate configuration is left exactly as you set it Bug Fixes
• Sorting the attribute list by the Markup column now orders the values as numbers. They were compared as text, which put 10 ahead of 8 — noticeable on an attribute with many terms, such as a year or size range
• The Markup column and the term's markup field now show every value in the same notation. Markups saved by older releases kept the leading plus sign and trailing zeros they were typed with, so +1.00 and 1 sat side by side meaning the same thing. Stored values are not altered; only what is displayed
• Applying "Reapply markups" on the product list with only simple products selected no longer repeats the previous run. Nothing was reported and nothing appeared to happen, but the products from the run before were quietly repriced again, using whatever markups were in place at that moment. A selection containing no variable products now says so and changes nothing
• Text you add to an attribute term's description is no longer left with a blank line or a stray indent where the markup annotation used to sit. The annotation is rewritten to the bottom of the description on every save, and lifting it out of its old position left the surrounding spacing behind. Only descriptions with text above or beside the annotation were affected The following shipped in 4.7.0 but were left out of that release's changelog.
• Markup values are now read correctly in stores that use a comma as the decimal separator, or a space or period for thousands. A value such as 1 000,50 could previously be misread when markups were applied from the product list
• A markup containing stray characters, such as 5abc, is now rejected rather than quietly stored as 5
• A markup typed with a space before the percent sign, such as 5 %, is no longer flagged as invalid in the browser. WooCommerce itself accepts that form, so the field now does too

Maintenance

• The bulk actions are named in sentence case throughout, the way WordPress and WooCommerce name their own. "Reapply Markups" on the product list now reads "Reapply markups". Only the label changed
• One syntax dialect throughout the shipping code: short array syntax, lowercase true/false/null, and the quote style needing fewer escapes. No change in behavior — pinned by the test suite
• Docblock boilerplate trimmed without losing documentation: @since no longer appears on private or protected members, and the identical singleton scaffolding is described in one line instead of seven

4.7.0 Release Date: August 2026 Changed

• Markup annotations now follow the markup type wherever they appear. Percentages read as words — (Add 5%) and (Subtract 5%) — and currency amounts read as signed values — (+$5.00) and (-$5.00). Previously the options drop-down and the attribute term name could describe the same markup two different ways on a single product. Bug Fixes
• "Reapply markups to prices" no longer vanishes from the variations [Bulk actions] menu after clicking [Save attributes]. WooCommerce rebuilds that whole panel, which discarded the menu entry until the page was reloaded. This bug was present in every prior release
• A failed markup reapplication on the product edit page now reports the failure instead of silently doing nothing. The error message existed and had been translated for years, but nothing could ever display it
• Markup meta is now written only for the attribute terms a product actually uses, instead of for every term in the attribute. Existing excess entries clear themselves on the next reprice — no action needed
• Bulk reapply from the product list no longer re-runs when the page is refreshed, bookmarked, or revisited with the back button
• A failed row refresh on the product list no longer leaves the reapply icon stuck, requiring a page reload before that row could be repriced again
• Attribute options no longer save under the wrong taxonomy when an attribute's slug differs from its label
• Products with no variations no longer produce a malformed database query during markup processing
• The invalid-markup error notice now appears when adding a term, not only when editing one
• The database upgrade runner now orders by version number rather than filename, which would have misordered at double-digit versions
• Deleting a term while its markup was being saved no longer triggers a PHP error Maintenance
• Confirmed compatibility with WordPress 7.1, WooCommerce 11.0.1, and PHP 8.4
• Substantial internal cleanup: retired a global, unified the price-handler API, extracted shared bulk meta read/write, and split the term-save handler into single-purpose methods. No change in behavior — pinned by the test suite
• License is now consistently GPL-3.0-or-later across the plugin header, class docblocks, and readme
• Markup column sorting is now applied only on the attribute term admin screen
• Normalized all line endings to LF

4.6.3 Release Date: June 2026 Security

• Added capability checks (edit_products / manage_product_terms) to all AJAX handlers and attribute option writes, alongside existing nonce checks
• Escaped all admin-facing output to close a stored-XSS vector via malicious or compromised translation files
• Escaped literal underscores in meta-key LIKE queries so cleanup matches only intended keys
• Prefixed all global PHP constants with MT2MBA_ to avoid collisions with other plugins Bug Fixes
• Markup reapplication is now truly atomic — fixed nested-transaction handling so a mid-run failure rolls back every price change instead of leaving partial updates
• Invalidate variation caches after bulk price edits so a stale cache can't revert changes when the product is saved
• Stopped the Markup term column from wiping content other plugins add to the attribute term list
• Fixed a possible regular-expression error when stripping markup annotations under certain translations
• Fixed the term-save recursion guard so batch term updates process every term, not just the first Performance
• Product list no longer loads product data for columns belonging to other plugins

FIX: Ensure documentation is clear that this works on “global” attributes. FIX: Version 2.3 exposes a problem in an earlier version's database conversion where percentage markups show incorrectly in the options drop-down (for instance, a 10% markup on $40 shows as $10 instead of $4). To patch around it, version 2.3 will put the percentage in the drop-down instead of the actual markup. These items will need to have their regular prices reset to have the actual markup appear. 2.2 FIX: Plugin name and description. FIX: Markup calculation on sale prices when using a percentage markup (percent of the regular price, not sale price). FIX: Clear Markup-by-Attribute metadata from the database on variation deletion. 2.1 FEATURE: Organize the Settings page with subheadings. FEATURE: Provide a link to the wiki from the Settings page. FEATURE: Expand wiki to include help with settings. FIX: Improve readme.txt readability. 2.0 FEATURE: The new Settings page allows for increasing the number of variations that can be created at a time (override WooCommerce's limit of 50). FEATURE: The new Settings page allows for modifying the way pricing markup is added to the variation descriptions (overwrite, append, or ignore). FEATURE: The new settings page allows configuration of the way the markup is displayed, including the number of decimals and the currency symbol. FEATURE: Markup description now enclosed in tags and can be modified with CSS (#mbainfo {}). FEATURE: Markup description added to the attribute term description and can be seen in the attribute term list. FEATURE: Markup is now saved as a floating-point number and not limited to only two digits below the decimal point. FEATURE: Database and code change to enhance supportability. FIX: Corrected issue where Increase/Decrease Regular/Sale Price functions calculated based on variation price rather than base price, yielding incorrect prices when percentages were used. FIX: Corrected issue where Increase/Decrease Regular/Sale Price functions did not update variation descriptions. FIX: Corrected issue where markup in the options drop-down was calculated from the sale price. 1.3.2 FIX: Eliminate bug where default variation options were not being selected and Choose an Option was always shown. 1.3.1 FIX: Remove the error_log() statement accidentally left in. 1.3 FEATURE: Added class backend-pointers for inline instructions. FEATURE: Added instructions link to Plugins page. FIX: Use only regular price markup in the attribute drop-down on the frontend. Percentage markups were appearing different in the dropdown and variation description. 1.2.0
