Fakturownia integration — what can you connect Fakturownia with in 2026?

Fakturownia is one of the most popular invoicing and sales management applications in Poland. Its greatest strength lies in extensive integrations that allow you to connect the program to other systems and automate processes. On the Fakturownia website you can find dozens of plugins and add-ons that make working with invoices efficient and enjoyable — integrations cover e-commerce platforms, payment modules, bank transaction imports, and ERP systems. In this article we present the most interesting integrations for 2026 and explain why integrating with Fakturownia may prove essential.

Why are integrations so important? Business trends 2025–2026

The e-commerce and B2B market is growing very fast. According to an Ifirma analysis, as many as 81% of B2B customers already buy online, and 64% of companies plan to increase their share of online sales. Experts forecast that in 2026 purchases will be more automated, social, and data-driven. Companies expect automation of the entire purchasing cycle — from price lists to settlements — and integration with KSeF, ERP, WMS, and deferred payments. If you run an online store or a service business, integrating Fakturownia with your sales systems, warehouse, and bank is becoming not a luxury but a necessity.

The National e-Invoice System (KSeF) will force the transition from traditional paper invoices to structured e-invoices in XML format. Fakturownia has been preparing a new integration with KSeF 2.0 since 2025 and invites entrepreneurs to test it. Demo version 1.0 was disabled because the Ministry of Finance shut down the test environment. Integration with KSeF allows sending sales invoices, downloading cost invoices, and automatically handling the process without logging into the MF system. This is one of the most important integrations of 2026 — its absence may prevent legally compliant invoicing from 2026 onward.

Integration categories in Fakturownia

The Fakturownia.pl/apps page divides applications into several categories. Below we discuss the most important ones and provide examples.

1. E-commerce platforms and marketplaces

Integrations with store platforms allow automatic invoice generation for orders placed in your store. This means you do not have to copy data manually, reducing the risk of errors.

- PrestaShop — the Fakturownia + PrestaShop module enables store-to-invoicing system integration. It automatically generates sales documents for orders and reduces the time needed to handle payments.
- Shoper — the integration enables creating invoices and receipts after order status changes and sending documents directly to the customer. The plugin is paid (14-day trial, then 249 PLN net per year).
- WooCommerce — the Fakturownia + WooCommerce module automatically creates invoices for orders, sends documents upon status change, and only requires the store address and API key.
- Shopify — the Fakturownia integration with Shopify links the invoicing process with shop orders.
- Allegro — the Fakturownia + Allegro app automatically creates sales documents for orders from the marketplace platform and allows customization of the invoicing process to suit business needs.
- Selesto, Selly, and HashMagnet — Polish e-commerce platforms offering ready-made online stores; their integration with Fakturownia simplifies invoicing and sales management.
- Bookero, Calendesk, and myVOD — online booking systems and course sales platforms. Integration with Fakturownia enables automatic invoicing of booking services.

2. Payment and financing modules

Online payments are gaining importance — customers expect fast payment methods, and businesses want payments matched to invoices. Fakturownia offers several built-in integrations:

- Quick Transfer — allows customers to pay invoices quickly.
- Bank account connection — automatically connects the Fakturownia account to any bank, fetches transactions, and displays the balance.
- PayU, Przelewy24, Tpay, Stripe, PayPal, Braintree, BitPay payments — Auto-payment modules enable customers to pay with one click. For PayU and Przelewy24, Fakturownia provides configuration that lets customers pay an invoice immediately; similar capabilities are offered by Tpay and Braintree. Integrations with Stripe (e.g., through striptu, which automates the transfer of invoices between Stripe and Fakturownia.pl) and PayPal facilitate payment imports and payment method configuration. BitPay integration addresses the growing popularity of cryptocurrency payments.
- Brutto — an invoice financing platform that enables quick financing of issued invoices without waiting for payment from the counterparty.

3. Bank transaction imports

Manually matching bank transfers to invoices is one of the most time-consuming processes. Fakturownia offers over a dozen integrations that import CSV, MT940, or XLSX files from banks. Examples:

- PKO BP, Pekao, Santander, ING Business, Moje ING, mBank, BNP Paribas, Millennium, Alior Bank, Credit Agricole, Citi Handlowy, Volkswagen Bank, BPS SA, Nest Bank, Revolut — each of these integrations allows importing transaction history files and matching them to payments in Fakturownia. Some banks provide files in CSV and MT940 formats, and BNP Paribas also supports XLSX.
- Custom CSV import — the module allows importing any transactional data from a CSV file and mapping columns to fields in Fakturownia.

4. Exports to accounting software and KSeF

Fakturownia simplifies cooperation with accounting firms by enabling invoice exports to popular systems:

- KSeF XML export — available in two versions (fa-2 and fa-3). Allows exporting invoices from Fakturownia to XML files compliant with ministerial structures. Useful if your accountant manually uploads invoices to the KSeF system.
