Integrating ThriveCart with fakturownia.pl

ThriveCart is a valued platform for selling digital products that automates the checkout process and sends detailed transaction confirmations with product breakdowns, taxes, and a link to download a PDF invoice. The Pro+ version also allows bulk downloading of invoices as a ZIP package. Unfortunately, even such extensive features do not guarantee compliance with Polish regulations — documents are only in PDF format, without the structure required by KSeF, and do not contain all fields required on a VAT invoice.

Fakturownia.pl, on the other hand, offers a complete online accounting system: it generates VAT invoices, supports various tax rates, creates JPK files, and from 2026 will send and receive e-invoices through KSeF. Integration with this tool eliminates the need to manually copy data from ThriveCart and ensures compliance with local law. In this article, we will show step by step how to connect ThriveCart with fakturownia.pl using striptu.com — a simple, Polish integration solution.

Why is it worth integrating ThriveCart with fakturownia.pl?

- ThriveCart generates only PDF invoices. Despite detailed notifications, they do not meet KSeF requirements, which from 2026 will require sending structured e-invoices.
- Limited numbering customization. You can add a prefix and set numbering only to a higher value, but you still cannot customize the invoice to Polish standards (no NIP, GTU codes, or Polish date format).
- No integration with Polish accounting systems. Simply downloading ZIP invoices in Pro+ does not solve the problem — you must manually import documents into your accounting software.
- Automation saves time and eliminates errors. Copying data from emails or PDFs into Fakturownia is a tedious task that can easily be automated with webhooks and API.

What is striptu.com?

Striptu.com is a SaaS service integrating popular sales platforms (including ThriveCart, Kajabi, and Stripe) with Polish invoicing systems. Key features:

- Simple configuration. In a few minutes you create a service, connect the data source, and define the connection with fakturownia.pl.
- Compliance with Polish regulations. Generated invoices contain all required fields and can be sent to KSeF.
- Local support. Documentation and customer service are in Polish; the tool is developed with the needs of Polish digital creators in mind.

Step 1: Create a service and select ThriveCart as the source

1. Register or log in at striptu.com.
2. In the main panel, go to the Services section and select Create new service.
3. Name the service (e.g., "ThriveCart Course 2025") and proceed to the next step.
4. In the "Select data source" step, you will see a list of platforms: Stripe, Kajabi, and ThriveCart. Select ThriveCart. The system will generate a unique webhook address. Click Enable integration to activate it, and copy the URL.

Step 2: Add webhook in ThriveCart

The webhook enables passing information about each transaction to striptu.com. To add the link:

1. Log in to your ThriveCart account.
2. From the top menu, select Settings, then go to the API & Webhooks section (in some versions called Webhooks & Notifications).
3. Click the Add webhook button.
4. In the Webhook URL field, paste the address copied from striptu.com.
5. Select the events (usually Order success or Order created, and Subscription payment) that should trigger the webhook. Save the settings.

From now on, after each sale ThriveCart will send order details (customer name, email address, amount, currency, and transaction date) to striptu.com, which will convert them into an invoice in the Fakturownia system.

Step 3: Configure the connection with fakturownia.pl

1. Return to the striptu.com panel and select Fakturownia as the target invoicing system.
2. Enter the Account name — the subdomain through which you log into Fakturownia (e.g., yourcompany for the address yourcompany.fakturownia.pl).
3. Paste the API Token generated in Fakturownia (Settings > Users and permissions > API Tokens).
4. Click Test connection to make sure the data is correct. In case of errors, check the spelling of the name and token.
5. Set the default VAT rate for transactions if you do not use the Taxes module in ThriveCart (e.g., 23%, 8%, or 0%). You can also enable automatic email sending of invoices to customers — the system will use the address provided in the transaction.
6. Finally, click Save integration settings. From now on, the system will automatically create VAT invoices in Fakturownia for every ThriveCart transaction.

Step 4: Prepare for KSeF

Fakturownia has announced full integration with KSeF from 2026. Thanks to this, invoices generated by striptu.com will be able to be automatically sent and registered in the ministry system. It is already worth familiarizing yourself with the e-invoice mechanism and making sure that all data (buyer NIP, company address, country code) is correctly entered in ThriveCart — they will be passed to Fakturownia and used in KSeF.

Alternative integration methods

You can of course use universal automation tools such as n8n, Zapier, or Make. They allow receiving webhooks from ThriveCart and triggering actions in Fakturownia through API. However, this requires workflow configuration, field mapping, and testing. For course creators who want to achieve their goal quickly, striptu.com is a simpler solution: it works right away, handles the data required on an invoice, and provides local support.

Summary

Integrating ThriveCart with fakturownia.pl using striptu.com is a way to automatically and legally invoice digital sales. Through the generated webhook, you pass transaction data to the Polish accounting system, and striptu.com takes care of numbering, VAT rates, and corrections. In a few steps you configure the service, connect it with ThriveCart and Fakturownia, and can forget about manually issuing invoices. You are also preparing for the upcoming era of e-invoicing, as Fakturownia and striptu.com will jointly support KSeF. This gives you more time to grow your business, and accounting stops being an obstacle to scaling sales.
