POP – Free European electronic invoicing for e-commerce (ex-WooPop)

POP is an e-invoicing compliance plugin for WooCommerce, Paid Memberships Pro and Cozmos PMS. It focuses on structured XML and on the full e-invoicing lifecycle, including generation and validation, network submission and, if enabled, digital signature and compliant archiving. With POP you pay a subscription and receive a monthly allocation of API credits. One credit equals 1 API call, for example: generate or validate XML, submit to a network (SdI, PEPPOL and others), plus signature and archiving when enabled. The principle is simple: you know in advance what you spend, and monthly costs remain predictable. POP supports country-specific e-invoicing workflows for Italy, San Marino and Belgium, including direct delivery to Italy’s Exchange System (SdI) and Belgian structured e-invoicing support. POP can also be used by businesses in the Netherlands, France, Germany and the United Kingdom through PEPPOL, by generating structured UBL-XML and routing invoices via a certified Access Point. Regulatory requirements differ by country, and users should verify their specific obligations. International PEPPOL Support (NL, FR, DE, UK) POP enables sending structured XML e-invoices to customers in the Netherlands, France, Germany and the United Kingdom through the PEPPOL International network, using a certified Access Point. Unlike Belgium, these countries do not require mandatory B2B e-invoicing, but many businesses still request PEPPOL delivery for interoperability or internal compliance. POP provides the technical capability to route invoices internationally. Regulatory requirements may vary by jurisdiction, and users should verify their own obligations. POP is also available for Shopify: apps.shopify.com/pop-european-invoicing POP is available in five plans (Free, Basic, Growth, Pro and Enterprise). For paid features, visit: https://popapi.io/en/prices/. Below are the features included in the Free plan. Document Generation & Delivery

Network and supported formats POP is designed to operate within structured European e-invoicing ecosystems, supporting both national interchange systems and the PEPPOL international network. It enables compliant document generation and routing according to the technical and regulatory requirements of each jurisdiction. Supported transmission networks

• Italy – SdI (Sistema di Interscambio) Direct transmission of structured XML invoices to the Italian Exchange System (SdI), where B2B and B2C e-invoicing is mandatory.
• PEPPOL network (via certified Access Point) Transmission of structured e-invoices through the PEPPOL international network, including:
• Belgium (mandatory B2B e-invoicing for VAT-registered businesses from January 1st, 2026)
• Netherlands
• France
• Germany
• United Kingdom In Belgium, structured B2B e-invoicing is implemented via PEPPOL. In other listed countries, PEPPOL delivery may be required contractually or for interoperability purposes, depending on the business context. Regulatory obligations may vary by country and transaction type. Users remain responsible for verifying their specific compliance requirements.

Supported document formats

• Structured XML e-invoices, including UBL where applicable
• PDF invoice copies (human-readable representation)
• Credit notes in XML and PDF format
• Fiscal receipts, where supported by the configured workflow POP supports B2B e-invoicing use cases. B2G use cases are not currently supported.

POP API and Integrations POP includes all integrations previously offered as paid add-ons (such as automatic interchange system submission, qualified electronic signature and certified digital preservation), now built directly into the plugin depending on your selected plan. Thanks to these built-in capabilities, POP works as a complete invoice generation plugin, automating XML creation, signing, transmission and long-term preservation through a fully structured, compliant e-invoicing workflow. Invoice Options With POP you can customize your invoicing workflow by configuring:

• Invoice prefix and suffix
• Automatic progressive numbering
• Custom fields (Tax Code, Destination Code and more)
• Automatic sending of PDF invoices via email
• HTML invoice display

Supported Payment Methods

• Cash
• Bank Transfer
• Check
• Payment Cards
• SEPA Direct Debit

Compatibility POP is compatible with the latest versions of WordPress and WooCommerce:

• WooCommerce: up to version 9.x.x; HPOS supported starting from WooCommerce 9.x.x
• PHP: 5.6 or higher
• WordPress: 4.6 or higher For HPOS and optimal performance, we recommend using WordPress 6.x.x and WooCommerce 9.x.x and up. We understand how frustrating it can be to navigate complex tax regulations, cumbersome tools, and the fear of making costly mistakes. We've been there too. It is precisely from these daily challenges that POP was born: a practical solution to real problems. We didn't want just another software. We wanted a simple, immediate, and truly useful solution. A way to automate tax management, reduce time wastage, and make room for the growth of your business, without the burden of bureaucracy. POP is born from direct experience. It is designed to be clear, reliable, and perfectly integrated into your daily workflow. We can’t make compliance sexy, only easier.

6.7.1 - 18/02/2026

• Fix: POP API quota exceeded responses now show a readable quota-limit message instead of raw JSON output.
• Add: Dedicated quota-limit UI message for wp_die with bold title, quota usage details, and actionable upgrade/refresh steps.
• Fix: Admin error email for quota-limit events now sends a clear human-readable message instead of raw API JSON.
• Add: New translation strings for quota-limit title/messages in POT and PO catalogs (it_IT, fr_FR, es_ES).
• Add: Unit test coverage for quota-error payload parsing, detection, message formatting, and HTML output.
• Change: Replaced legacy WooPop/WooPOP/WooPoP naming with POP in user-facing localized strings across PHP/JS, file headers, and comments (without changing technical identifiers).
• Fix: Updated affected translation catalogs and rebuilt locale binaries for changed domains (.po/.mo).
• Fix: Bootstrap environment loading now fails safely in dev mode when config/environments/dev.php is missing (admin notice + early return), preventing unintended fallback to production config.
• Add: PMPro admin order screen now includes on-demand billing sync buttons in "Invoice Fields" to recover missing POP fiscal/billing data from the linked user profile.
• Add: PMPro admin order save flow now supports two explicit sync modes from user profile (fill_missing, overwrite) before persisting order metas.
• Change: POP profile invoice fields are now centralized in a single global WordPress user profile block (shared across providers), with one save path to user meta billing_*.
• Fix: Removed duplicate PMPro profile show/save hooks to avoid multi-source profile saves and key collisions on shared POP billing fields.
• Fix: In WordPress user profile screens (profile.php, user-edit.php), duplicated WC/PMPro POP fields are now forced read-only via disabled state while keeping the centralized global POP block editable.
• Add: Admin profile hardening script to enforce disabled duplicated provider fields and inject a contextual notice with anchor link to the centralized POP section.

6.7.0 - 17/02/2026

• Add: DB advisory lock helpers based on MySQL/MariaDB GET_LOCK/RELEASE_LOCK to prevent concurrent duplicate create/send/upload actions.
• Fix: Fatture in Cloud send flow now requires explicit docID and wfc-issued_send_document=false; removed implicit docID fallback from stored document meta.
• Fix: Fatture in Cloud create flow now uses atomic lock guard to avoid duplicate issued documents under concurrent Ajax/Cron execution.
• Fix: Added channel guards to SDI/PEPPOL/FIC status callbacks so native/addon flows run only when their integration channel is effectively active.
• Fix: Hardened _invoice_sent writes across channels (SDI native, PEPPOL, Aruba, SDI via PEC, FIC) by requiring minimum success/coherence conditions before setting sent.
• Fix: Added recurring cron cleanup for inactive/disabled upload schedules (FIC, Aruba, SDI via PEC) to avoid orphan scheduled events.
• Fix: Fatture table invoice number rendering now only shows dismiss icon when both order_number_invoice and formatted number are missing, with recovery from formatted where possible.
• Add: Native SDI/PEPPOL timeout-pending flow with explicit admin recovery actions in order list (Confirm UUID / Cancel timeout).
• Add: New admin AJAX actions confirmNativeSendWithUuid and cancelNativeTimeoutPending to finalize or clear timeout-pending state safely.
• Add: Native timeout helper set (meta keys/channel prefix/timeout detection) and centralized timeout pending metadata management.
• Fix: SDI and PEPPOL create/send flows now mark timeout-pending on timeout-like provider responses and clear pending state on successful UUID save.
• Fix: SDI and PEPPOL create/send error responses now include readable provider detail extracted from raw payload data when available.
• Change: Timeout pending UUID input in native actions UI is now full-width with explicit spacing before recovery buttons.
• Fix: getNextInvoiceNumber now aligns stale next numeration values to max(next, last_assigned+1) for the active series, preventing duplicates and backward numbering.
• Add: series-aware duplicate check now uses WooCommerce order queries (HPOS compatible), comparing type/prefix/year context against the latest assigned order.
• Add: provider-level series hooks for PMPro and Cozmos addons via wc_el_inv-next_number_already_assigned and wc_el_inv-next_number_last_assigned_for_series.
• Add: Extended unit test coverage for timeout helpers, native error detail extraction, resolver hardening edge cases, and wrapper/adapter behavior.
• Fix: Resolver hardening for invalid filter outputs (channels status/priority), empty priorities, non-string priority entries, and normalized shop country handling.

6.6.2 - 13/02/2026

• Fix: WooCommerce Blocks checkout now reliably saves POP additional billing fields into order meta during checkout completion.
• Fix: Restored JS validation flow for invoice fields in block checkout after the legacyId refactor regression.
• Fix: In PEPPOL context, billing_sdi_type is now always ignored/emptied on save for both WooCommerce classic and block checkout flows.
• Fix: In PEPPOL context, _billing_sdi_type and related SdI labels/help text are hidden in WooCommerce admin billing edit/view.
• Add: New "Tax information" section on order confirmation, rendered after billing address for both classic and block checkout.
• Change: Tax information output now appears only when fiscally meaningful data is present (company/freelance with VAT, private with tax code).
• Removed: Legacy billing-address formatting hooks for POP tax fields replaced by dedicated Tax information rendering.

• Fix: PMPro renewals now always restore billing/fiscal data (private: codice fiscale; company/freelance: P.IVA/SDI) from user or previous order, avoiding loss when SDI is absent.
• Change: document date now always uses emission time (now); od_date uses operation date for invoices or linked document date for credit notes; invoice_date for credit notes uses the linked invoice date.
• Removed: hook 'wfc-create-invoice_datetime-invoice' to prevent external overrides on od_date.
