What people say

Built for the way EU teams actually invoice.

FAQ

Common questions.

Do I need to install anything?
No. Flowtark runs in any modern browser. If you'd like, install it as a PWA on your phone or laptop home screen — it works offline for the app shell.
Where is my data stored?
On EU servers, with daily backups. From Settings you can export your full account as JSON and delete your account at any time — both GDPR rights, fully self-serve.
Can I customize the PDF?
Yes — on Solo and above. Add your logo, pick a brand color, and your invoices come out looking like they belong to you, not us.
Which countries are supported for VAT?
Any EU member state for VIES verification. Reverse-charge is auto-applied for non-EE EU clients (0% VAT, line marked on the PDF). Non-EU clients are billed at your default VAT rate.
Can I switch plans or cancel?
Yes — straight from the in-app billing portal. No retention forms, no email gymnastics.
What happens after the 14-day trial?
You drop back to the Free plan unless you upgrade. Your data stays. Excess clients get marked as frozen — visible but unusable until you upgrade or remove them.
