wFirma integration.
Invoicing that keeps up with your sales.
Orders come in from marketplaces, online stores and other channels, and every one of them needs a sales document in wFirma. Retyping invoices, corrections and receipts by hand means delays, errors and extra work for the team.
The wFirma integration with Base connects multi-channel sales with your accounting. Base sends invoices, corrections, proformas and receipts to wFirma, and imports products, stock and prices from wFirma. Base stays the order fulfillment hub; wFirma stays the source of accounting and product data.

What problems does the wFirma integration with Base solve?
Retyping invoices takes up the team’s time
Every sale has to reach the accounting system. With a high volume of orders, copying data into wFirma by hand quickly becomes a bottleneck. With the wFirma integration, Base sends invoices to wFirma automatically when they are issued, or you send them from the invoice list or export them in bulk. Base sends the invoice data, not a file, so wFirma holds a complete, editable document.
Corrections, receipts and proformas need the same care as invoices
Returns, B2C sales and advance payments create documents too. The wFirma integration supports corrections, proformas and receipts, not just invoices. Fiscal receipts go through a fiscalization flow in wFirma, and a proforma can create a reservation document in wFirma.
The product catalog in accounting and in sales channels drifts apart
When a name, price or EAN changes in one place, it rarely changes everywhere. The wFirma integration imports products from wFirma into Base, with the wFirma product code as SKU, plus EAN, name, description, quantity, gross price, VAT rate, weight and dimensions. You build your Base catalog on wFirma data instead of keeping two catalogs.
Stock levels can’t keep up with multi-channel sales
Selling in several stores and marketplaces at once raises the risk of selling a product you no longer have. The wFirma integration syncs stock from wFirma to Base. You choose one wFirma warehouse, or take quantities from all warehouses, and Base uses that stock to update offers across your channels.
Prices need updating in many places at once
Promotions and cost changes should reach every channel quickly. The wFirma integration imports prices from a wFirma price group you select, so prices are maintained in wFirma and used for sales in Base.
Accounting automation for multi-channel sales
Connecting accounting software is only part of the job when you sell on several marketplaces, stores and markets at once. Base connects wFirma with the whole ecommerce process: orders, documents, stock, shipping and customer communication.
Try it for freeAutomatic, manual or bulk invoice export
You don’t have to send documents one by one. Base can forward invoices and proformas to wFirma automatically, and you can send invoices from the invoice list or export a batch, for example for a whole month.
Numbering from Base or from wFirma
You decide where document numbers come from. Invoices can keep the Base number, or wFirma can number them using the series you select in the integration settings.
VAT, OSS and foreign-currency invoices
The wFirma integration handles net or gross pricing, OSS VAT for cross-border EU sales and invoices in foreign currencies. OSS uses your country and VAT-rate mapping, and foreign-currency invoices can use a dedicated payment account. Receipts are issued in PLN.
Invoice PDFs from wFirma in Base
Base can download the invoice PDF from wFirma and use it in the order process, for printing, emailing to the buyer or attaching in automations. For fiscal receipts, printing stays in wFirma.
Why do merchants connect wFirma to Base?
More than 1,400 online sellers use the wFirma integration with Base, and together they send over 400,000 invoices to wFirma every month.
Multi-channel sales without operational chaos
Base collects orders from every channel in one panel, and the wFirma integration links them to accounting. Instead of managing the store, marketplace, warehouse and accounting separately, the team works in one connected process.
wFirma as the data source, Base as the sales centre
wFirma holds accounting, product and stock data. Base handles daily order processing and the integrations with marketplaces, stores and couriers. Each system does what it does best.
Automations that cut manual work
Workflow automation in Base changes statuses, emails customers, creates shipments and passes data on. The wFirma integration adds invoices, corrections, receipts, products, stock and prices to that process.

How do I set up the wFirma integration in Base?
Run the integration without building your own API connection
You don’t need to build your own API connection between your sales system and wFirma. In Base, add wFirma under Integrations → Accounting/ERP → wFirma.pl and sign in to your wFirma account; there are no API keys to copy. Then choose:
- the wFirma company to work with, if you manage several
- where document numbers come from: Base or a wFirma series
- VAT, OSS and net or gross pricing
- payment method mapping and payment dates
- how invoice items are linked to wFirma products: by SKU, EAN or PKWiU
- the wFirma warehouse for stock, or all warehouses
- the wFirma price group for price import
