Written by the person who answers.

Flowzivo is small. There is no support queue and no chatbot: mail goes to me, Mattia, and I answer it myself. That means replies are not instant, but they are from someone who can actually change the product — and you never have to explain your problem twice.

Ask me the question your invoicing software cannot answer.

Do I charge VAT to a client in Germany? What does my invoice have to say for reverse charge to hold up? Which currency do I invoice in, and at what rate? FreshBooks will not tell you, and your accountant charges by the hour. I work as a fiduciary — write me the situation in three lines and I will answer it.

Ask the question No account needed, and no obligation to use Flowzivo afterwards.

Write about anything

Something is broken. Tell me what you did and what happened. If you can, say which browser — it usually narrows it down in one step.
Something is missing. Say what you were trying to get done, not what feature you want. The first is more useful than the second.
Cross-border invoicing. Reverse charge, VAT numbers, invoicing a client in another country — I work as a fiduciary, so this is the part I actually know.
Billing and cancellation. You can cancel yourself from Settings → Cloud account, but if something looks wrong on an invoice from us, write and I will fix it.

Who is behind Flowzivo

Flowzivo is built and operated by ITG Suisse Sagl, Corso Elvezia 25, 6900 Lugano, Switzerland — a company that builds digital products and services for businesses operating in Switzerland.

I work as a fiduciary, which is why cross-border invoicing is the part of this product I actually know. For years I have received invoices made in Word, numbered by hand, with the VAT treatment guessed — not because the people sending them were careless, but because the tools were either an ERP they did not need or a template that knew nothing about the rules.
