"twitter:title": "Fakturownia Integration for Rental Businesses in Poland" --- ![Fakturownia Integration for Rental Businesses in Poland](https://requiply.com/.netlify/images?w=10&h=10&fm=webp&q=50&blur=3&url=%2Fblog%2Ffakturownia-integration%2Fcover.png) ## How do I invoice a rental booking in Fakturownia? Connect your Fakturownia API token once under **Settings → Integrations → E-invoicing**, then open a booking and choose **Issue invoice in Fakturownia** from its actions menu. Requiply sends the equipment, services, prices, VAT and buyer from the booking to Fakturownia, and Fakturownia numbers the invoice, makes the PDF and, if your account has KSeF connected, sends it to KSeF. > **Screenshots are in Polish.** Fakturownia is a Polish invoicing app used by companies that invoice in Poland, so this guide shows Requiply and Fakturownia in Polish. The English names of every button are in the text. The integration is in **Beta**: it works, and Fakturownia is verifying it at the same time. ## Who This Integration Is For If you already invoice in Fakturownia, you keep it. Numbering, templates, company details and the KSeF connection stay where they are. Requiply stops being the place you copy bookings from and does the copying for you. If you don't use an invoicing app and want to send invoices straight to KSeF, use the [KSeF integration](https://requiply.com/blog/ksef-integration) instead. You can connect both: the booking's actions menu then lets you pick where to issue the invoice. Creates a VAT invoice in Fakturownia from the booking: equipment, services, discounts, VAT and buyer The invoice number and PDF come from Fakturownia, with your template and company details Fakturownia can send the invoice on to KSeF, and Requiply shows the KSeF number The client's NIP, company name and address fill in after the first invoice ## Step 1: Copy the API Token From Fakturownia Log in at [fakturownia.pl](https://fakturownia.pl/) and open **Ustawienia → API** (1). On the **Tokeny API** page, copy the **Kod autoryzacyjny API** (2). If the list is empty, click **Dodaj nowy Token**. ![The Tokeny API page in Fakturownia: the Ustawienia menu with API highlighted and the blurred API token field highlighted](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Ffakturownia-api-token.png) > **Fill in your company details in Fakturownia.** Fakturownia prints them as the seller, so it can't issue an invoice without them. Check **Ustawienia → Dane firmy**: the name, NIP and address must be filled in. Requiply checks this before issuing and tells you if something is missing. ## Step 2: Connect Fakturownia in Requiply Open [Settings → Integrations → E-invoicing](https://app.requiply.com/settings/integrations/einvoicing) (1) and click **Setup** on the Fakturownia card (2). app.requiply.com/settings/integrations/einvoicing ![The E-invoicing settings page with E-invoicing highlighted in the menu and the Fakturownia card with a Beta badge next to the KSeF card under Polish systems](https://requiply.com/.netlify/images?w=1728&fm=webp&url=%2Fblog%2Ffakturownia-integration%2Fsettings-page.png) *Fakturownia and KSeF share one page in the integrations.* Paste the token (1), enter your Fakturownia address (2) and choose whether Fakturownia sends invoices to KSeF (3): ![The Fakturownia connection dialog with three highlighted fields: API token, Fakturownia address twojafirma.fakturownia.pl and the Send invoices to KSeF switch, with the VAT status below](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Fconnect-dialog.png) | Field | What to enter | | --- | --- | | **API token** | The API authorization code from Fakturownia | | **Fakturownia address** | The address you open Fakturownia at, for example `yourcompany.fakturownia.pl` | | **Send invoices to KSeF** | On: Fakturownia sends every invoice to KSeF right after saving it. KSeF must be connected in your Fakturownia account | | **VAT status** | **VAT payer**, or **VAT-exempt** with the legal basis of the exemption | Click **Connect**. Requiply checks the token with Fakturownia before saving it, so a wrong token or address is refused straight away. > **VAT payers:** turn VAT on under **Settings → Pricing → VAT** before you create the bookings you want to invoice. Bookings keep the VAT they were created with, and Requiply takes the rates for Fakturownia from it. ## Step 3: Issue the Invoice From the Booking Open the booking and expand the actions menu (the arrow next to **Export**). You'll find **Issue invoice in Fakturownia** there (1). ![The booking actions menu with Issue invoice in KSeF and Issue invoice in Fakturownia, the latter highlighted](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Factions-menu.png) The dialog opens with everything filled in: - **Invoice number:** assigned by Fakturownia (1), following your numbering - **Buyer** (2): NIP, company name and address from the client's details or from the client's last invoice. For a private person, choose **Private person** - **Payment:** **Paid** when the booking is fully paid, otherwise **To be paid** with an optional due date - **Invoice lines:** every item and service on the booking with its price, discount and VAT rate ![The Issue invoice in Fakturownia dialog for booking #20: a note that Fakturownia sends the invoice to KSeF, the highlighted invoice number assigned by Fakturownia and the highlighted buyer filled in from the client's details: NIP, company name, street, postal code and city](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Fissue-dialog.png) Check the buyer and click **Issue in Fakturownia**. A moment later Requiply shows **Invoice issued in Fakturownia** with the number Fakturownia assigned, and the invoice appears in the booking's **Invoices** section. app.requiply.com/reservation/20 ![Booking #20 right after issuing: the Invoice issued in Fakturownia message with number 3/11/2026 and the Invoices card with the In Fakturownia status and a PDF button](https://requiply.com/.netlify/images?w=1728&fm=webp&url=%2Fblog%2Ffakturownia-integration%2Fissued-page.png) *The invoice number comes back from Fakturownia a few seconds after sending.* If something blocks the invoice, the dialog tells you before anything is sent. For example: a booking without VAT on a VAT payer account, or missing company details in Fakturownia. ## Step 4: Manage the Invoice on the Booking The **In Fakturownia** status (1) means the invoice is saved in Fakturownia. The PDF button downloads the invoice as Fakturownia prints it, and **Open in Fakturownia** (2) in the menu takes you to it in Fakturownia, for example to email it to the client. ![The Invoices card with invoice 3/11/2026, the In Fakturownia status highlighted and the Open in Fakturownia menu item highlighted](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Finvoice-menu.png) When Fakturownia sends the invoice to KSeF, Requiply follows its status. Once KSeF accepts it, the invoice shows its KSeF number, and the menu adds **Download UPO receipt** and **Download invoice XML**. If KSeF rejects it, you see the reason and an **Issue again** button. ## Client Details Fill In Themselves Requiply now has the client system fields invoices need: **NIP**, **Company name**, **Street and number**, **Postal code** and **City**. When you connect Fakturownia or KSeF, Requiply offers to add these fields to clients in one click. You can also turn them on under **Settings → Fields → Level configurations**, on the **Client** tab. With the fields on, the invoice dialog takes the buyer from them. And when a client doesn't have these details yet, Requiply saves them after the first accepted invoice: you type the NIP and address once, on the invoice, and they're ready next time. Requiply never overwrites details the client already has. ![The Details card of client Remonty Kowalski with the fields filled in after the invoice highlighted: Company name, NIP, Street and number, Postal code and City](https://requiply.com/.netlify/images?url=%2Fblog%2Ffakturownia-integration%2Fclient-fields.png) The same works with the KSeF integration. ## What It Doesn't Do Yet Requiply doesn't issue correction invoices, pro formas or advance invoices in Fakturownia yet, and it doesn't read payments back from Fakturownia. Handle those directly in Fakturownia. If KSeF rejects an invoice and you issue it again, Requiply creates a new invoice in Fakturownia, so delete the rejected one there. Need any of these?

Connect your Fakturownia API token in Requiply and invoice any booking from its actions menu. Requiply sends the lines, prices, VAT and buyer to Fakturownia, and Fakturownia numbers the invoice and makes the PDF. ### Do invoices issued through Fakturownia reach KSeF? Yes, when your Fakturownia account has KSeF connected and Send invoices to KSeF is on in Requiply. Fakturownia sends the invoice to KSeF right after saving it, and Requiply shows the KSeF number on the booking. ### How is the Fakturownia integration different from the KSeF integration? The KSeF integration builds the FA(3) invoice in Requiply and sends it straight to KSeF, so you need no invoicing app. The Fakturownia integration keeps numbering, templates and the KSeF connection in Fakturownia, which suits companies that already use it. ### Where does Requiply take the buyer NIP and address from? From the client fields NIP, Company name, Street and number, Postal code and City, and when those are empty, from the client's last invoice. After the invoice is accepted, Requiply saves what you typed into the client's empty fields. ### Can I connect several Fakturownia accounts? Yes. Connect one account per company and choose which one to issue from when you issue the invoice. One of the accounts is the default. ## Additional Information - **Who can set it up:** organization admins connect, edit and disconnect Fakturownia accounts. Anyone who can manage bookings can issue invoices. - **Where the token is kept:** Requiply stores it encrypted and never shows it again. To change it, use **Replace token** in the Fakturownia dialog. - **Full reference:** every field, status and message is described in the [knowledge base](https://requiply.com/docs). **Questions?** Write to us at `info@requiply.com` or [book a demo](https://requiply.com/book-a-demo), and we'll connect Fakturownia with you. **Tags** - fakturownia - ksef - poland - invoicing - vat invoice - equipment rental software - rental business - integration - requiply ## Sitemap See the full [sitemap](/sitemap.md) for all pages.
