Is Terminovo's free invoicing software really free?
Yes — permanently free and without any time restrictions. There is no trial period that expires after 14 or 30 days. The free plan is a fully functional version of the product and does not require a credit card. You can use it for as long as you like — and if your business grows, you can smoothly upgrade to a paid plan.
How many invoices can I issue for free each month?
The free Terminovo plan has no invoice limit. You can issue as many invoices as you need — both KSeF-structured invoices and standard PDF invoices. This sets us apart from many other free invoice programs that limit you to 5 or 10 documents per month and push you towards a paid plan.
Does the free plan support KSeF?
Yes, KSeF integration is available on all plans — including the free plan. Terminovo automatically submits issued invoices to the National e-Invoice System, validates the FA(2) schema before sending, and stores KSeF numbers against every invoice. No configuration is needed — the system works from the moment you register.
Can I upgrade to a paid plan later?
Absolutely. You can activate a higher plan at any time without losing any data or invoice history. If the need arises, you can also return to the free plan — your invoices and client data remain safe and accessible regardless of which plan you are on.
Is my data safe?
Yes. Data is stored on servers located within the European Union, in compliance with GDPR requirements. All connections are encrypted (HTTPS/TLS). We perform regular backups, and account access is protected by a password and optionally by two-factor authentication. We do not share data with third parties for marketing purposes.
Does Terminovo work on mobile?
Yes. Terminovo is a web application with a responsive interface — it runs smoothly in the browser on smartphones, tablets, and computers. You can issue invoices, check payment statuses, and send reminders from any internet-connected device. No native mobile app installation is required.
What invoice formats are supported?
Terminovo supports structured XML invoices in the FA(2) format required by KSeF, as well as PDF invoices for download and email delivery. Invoices can be issued in Polish or English. We support VAT invoices, VAT-exempt invoices, advance invoices, final invoices, and credit notes.
Can I import data from another program?
Yes, Terminovo supports importing client and product/service data from a CSV file. If you previously used another invoicing program, you can transfer your client database without manual re-entry. For more complex migrations — such as from an ERP system — our team can assist with integration. Contact us via the contact form.
