Stripto

What is Stripto?

Stripto is a Polish SaaS tool that automatically generates VAT invoices from Stripe payments and sends them to the Polish National e-Invoice System (KSeF) or to popular accounting platforms like Fakturownia, inFakt, and wFirma. It solves the problem that Stripe does not natively support Polish VAT invoicing or KSeF compliance. The service is designed for Polish businesses, freelancers, and e-commerce merchants who use Stripe for payment processing and need to issue compliant VAT invoices automatically. Stripto connects via API keys, requiring no manual data entry, and supports one-time payments, subscriptions, and payment links.

Key Features

• Direct KSeF Integration: Stripto can send invoices directly to KSeF or through integrated accounting systems. Users choose the preferred method during setup.
• Automatic Data Extraction: Customer details (NIP, company name) are pulled from Stripe payment metadata and placed onto invoices automatically, eliminating manual transcription.
• Multi-Platform Support: Works with Fakturownia, inFakt, and wFirma. Users connect their accounting platform via API key, and invoices are created there automatically.
• All Payment Types: Supports one-time charges, subscriptions, and Stripe Payment Links. Every successful payment triggers invoice generation.
• EU B2B Reverse Charge: Automatically detects B2B transactions within the EU and applies reverse charge (odwrotne obciążenie) on the invoice, ensuring tax compliance.
• Import Historical Transactions: Users can import past Stripe transactions to generate invoices for previous payments, not just new ones.
• Security: API keys and tokens are stored encrypted. Stripto uses restricted Stripe keys with read-only access, never sees customer card numbers, and cannot initiate transfers.

How It Works

A user signs up on Stripto.pl and connects their Stripe account by providing a restricted API key. This takes under a minute. Next, the user connects their accounting platform (Fakturownia, inFakt, or wFirma) or opts for direct KSeF submission by providing the relevant API key. Once both connections are active, Stripto monitors Stripe for new successful payments. When a payment occurs, Stripto automatically creates a VAT invoice in the connected accounting system or sends it directly to KSeF. The invoice includes customer data from Stripe metadata, applies appropriate tax rates, and handles EU reverse charge if applicable. Users can also import past transactions to generate invoices retroactively. The entire workflow runs without manual intervention after initial setup.

Use Cases

• A solo B2B SaaS founder using Stripe for subscription billing needs to issue VAT invoices for each monthly charge. Stripto connects Stripe to inFakt, automatically generating invoices with the customer's NIP and applying reverse charge for EU clients. The founder saves hours each month and stays KSeF compliant.
• An e-commerce store owner selling digital products via Stripe Payment Links. Every sale triggers an invoice in Fakturownia, which is then sent to KSeF. The owner no longer logs into the accounting system after each transaction, reducing administrative overhead.
• A marketing agency with multiple Stripe accounts for different clients. Stripto supports multiple Stripe connections, each linked to a separate accounting integration. Invoices are generated per account, keeping client finances separate and automated.
