External services

This plugin relies on the inFakt API, a third-party accounting service, to generate invoices and manage customer data.

What is inFakt API?

inFakt is a Polish online accounting system that provides invoicing and accounting services for businesses. This plugin uses their official API to:
* Create and manage customers (clients) in your inFakt account.
* Generate invoices and proforma invoices (PRO version).
* Retrieve bank accounts, VAT exemption reasons, and other accounting data from your inFakt account.
* Download invoice PDFs.
* Send invoices to KSeF (Polish National e-Invoice System) via InFakt (PRO version).

What data is sent and when?

The plugin sends the following data to inFakt API (https://api.infakt.pl/v3) in these situations:

When you click “Create Invoice” or when automatic invoice generation is triggered (PRO version):
* Customer billing information: first name, last name, company name, VAT number (NIP), email, phone number, billing address (street, city, postal code, country).
* Order information: order items (product names, quantities, prices, VAT rates), shipping details, payment method, order date, order total.

When the plugin connects to inFakt API (on settings page load or when needed):
* Your inFakt API key (for authentication).
* Requests to retrieve your account settings: bank accounts, VAT exemption reasons, income categories, flat rate tax options.

No data is sent automatically without your action. The plugin only communicates with inFakt API when:
* You manually create an invoice from the order screen.
* You enable automatic invoice generation in PRO version.
* You open the plugin settings page (to load account configuration).

變更記錄

1.0.25

  • Updated: Tested up to WordPress 7.0.

1.0.24

  • Updated: readme Pro purchase link text (Get PRO Version).

1.0.23

  • Updated: readme Pro CTA restored as subsection heading with bold link anchor.

1.0.22

  • Updated: readme Description layout (intro + bare YouTube URL for directory embed); Pro CTA link formatting.

1.0.21

  • Added: demo video link in readme (YouTube).

1.0.20

  • Fixed: VAT class mapping for WooCommerce “Standard” rate (empty tax class slug): product lines now respect ZW / 0% / NP mapping from plugin settings instead of skipping mapping and sending tax_symbol “0”, which broke invoices when vat_exemption_reason was set.

1.0.19

  • Fixed: paid amount on invoice (paid_price) is now sent to the inFakt API in minor currency units (grosze), matching other amounts — previously PLN values were interpreted as grosze, so e.g. 1199.00 PLN appeared as 11.99 PLN.

1.0.18

  • Updated: screenshot #4 (assets) for plugin directory.

1.0.17

  • Updated: screenshot #4 (assets) for plugin directory.

1.0.16

  • Added: optional setting (Invoicing) — sale date on inFakt invoice can match invoice issue date instead of WooCommerce order date; Polish translations and compiled pl_PL.mo.

1.0.15

  • Fixed: map WooCommerce payment gateways to inFakt API payment_method codes (transfer, przelewy24, paypal, delivery, card, etc.) instead of sending the checkout title string; added filter devikit_infakt_payment_method.
  • Fixed: payment due date calculation used an undefined variable when payment deadline days were set (now based on invoice issue date).

1.0.14

  • Maintenance: release republish (same codebase as 1.0.13 shipping VAT fixes).

1.0.13

  • Fixed: VAT on shipping lines now follows WooCommerce order data (tax amounts) and tax-class mapping (including Standard rate and zw/np/0), instead of inheriting from cart products or defaulting to 0% incorrectly. Shipping with tax class “inherit” falls back to product line rates when appropriate.

1.0.12

  • Improved: when billing address line 1 is street-only and line 2 contains building and/or flat (e.g. PL formats like 15/3, 15 m. 3), values are mapped to Infakt street_number and flat_number. Filters: devikit_infakt_parse_billing_address_line2, devikit_infakt_client_address_from_order.

1.0.11

  • Fixed: save_admin_order_nip – WooCommerce może przekazać WP_Post zamiast WC_Order; użycie instanceof WC_Order zapobiega błądowi “Call to undefined method WP_Post::update_meta_data()”.

1.0.10

  • Edytowalne pole NIP w meta zamówienia (sekcja adresu rozliczeniowego).

1.0.9

  • Walidacja sumy zamówienia vs faktura w kolumnie listy zamówień.
  • Opóźniona wysyłka e-maila (5 min) przy automatycznym tworzeniu faktur/proform.

1.0.8

  • Fixed Pro upgrade banner dismiss functionality (remind later and don’t remind buttons).

1.0.7

  • Small fixes.

1.0.6

  • Fixed default checkbox label translation on first installation.

1.0.5

  • Added plugin screenshots.
  • Updated readme descriptions.

1.0.4

  • Added Plugin URI for WordPress.org integration.

1.0.3

  • Removed “Including product variants in invoices” from Pro features list.

1.0.2

  • Fixed Pro banner title.

1.0.1

  • Added promotional banner for Pro version.
  • Updated feature list.

1.0.0

  • First public release.
