Optional support
Use it for free. Contribute only if you want to.
A small business or an accounting firm's client should not be blocked just because they only need to issue a few invoices.
PLN 0 is fine
Core use of fv.converts.ninja is free. There is no trial that stops working after a week simply to force payment.
If the platform helps, you may contribute any amount
Support is voluntary. It grants no special access to other users' data, does not change security and has no effect on whether your invoice can be sent to KSeF.
Wesprzyj rozwójPayment is handled outside fv.converts.ninja. The platform does not store card numbers or payment-instrument details.
No hidden subscription
If paid features for larger organisations, integrations or guaranteed SLAs appear in future, they will be described separately. A voluntary contribution never turns itself into a recurring subscription.
