Your benefits

Faster invoices. Full overview. Always compliant.

Invoices in minutes

Create professional quotes and invoices in just a few minutes — at your desk or on the move. The required fields are filled in for you, your customers and products are saved once and picked in a click, and the template adapts to your business. Less time on admin, more on the work that actually pays.

Always know who’s paid

See which invoices are paid and which are still open at a glance, so nothing slips through the cracks. Automatic payment reminders chase overdue invoices for you — no spreadsheets, no copy-paste — so you get paid faster and keep a clear overview even when business gets busy.

Compliant, automatically

Every quote and invoice carries the mandatory details and is archived as a PDF, with sequential numbering and VAT calculated for you. Each document is created, sent and stored automatically, so you can focus on running your business instead of the rules.

How it works

From quote to paid — fast & easy.

The quote becomes the invoice — and you always see whether it’s paid.

  1. 01

    Write the quote

    Pick a customer and add your products — tax and totals are worked out as you go.

  2. 02

    Turn it into an invoice

    Accepted? One click makes it the invoice — numbered, legally compliant, with the e-⁠invoice built in.

  3. 03

    Get paid

    See what’s paid and what’s open at a glance — overdue invoices get their reminders automatically.

E-⁠invoicing

E-⁠invoicing, done right — in your country.

Across the EU, businesses must be able to receive e-⁠invoices — and more and more have to send them. Invoice creates the right file for your country automatically, to the European standard EN 16931 — without touching a line of XML.

  • GermanyZUGFeRDXRechnung

    ZUGFeRD for business customers, XRechnung for authorities with a Leitweg-ID — both to EN 16931, created automatically.

  • FranceFactur-X

    Factur-X (EN 16931) with every French mandatory mention, including the SIREN numbers. Sending through a certified platform (PA): in preparation.

Professional invoices & quotes

Create polished invoices and quotes in minutes — no template wrestling, no legal guesswork. Everything a proper document needs is filled in as you go.

  • Your branding: add your logo and letterhead so every document looks unmistakably yours.
  • VAT calculated: each item brings its rate, and the totals are worked out as you add it.
  • Correct by default: the required details are always included, so nothing is ever missing.

Every document you need

Run the whole billing cycle from one place — not just invoices. Whatever the job calls for, the right document is a click away.

  • Quotes & invoices: send a quote, then turn it into an invoice in one click once it’s accepted.
  • Recurring & reminders: let regular invoices go out on schedule and overdue ones remind themselves.
  • Corrections & cancellations: correct or cancel a document cleanly — the original and the cancellation both stay on record.

Get paid, on time

Keep the cash flowing without the chasing — see exactly what’s outstanding and let automatic reminders do the follow-up for you.

  • Paid vs open at a glance: every invoice shows its status, so you always know where you stand.
  • Automatic reminders: overdue invoices get polite, staged reminders — no awkward emails to write.
  • Mark payments in seconds: record a payment and the invoice updates itself, no bookkeeping detour — and reverse a wrong one.

FAQ

Frequently asked questions

Short answers to what people ask us most.

Can I try Invoice for free?

Yes. Every plan starts with a 14-day free trial — no credit card needed — so you can try Invoice in full before you pay. There is no permanent free tier: when the trial ends you simply pick the plan that fits.

What happens after the 14-day free trial?

Nothing happens automatically — no credit card is required, so you are never charged without choosing. When the 14 days are up you pick the plan that fits your business. If you are not ready, access simply pauses — nothing is charged and your data stays safe until you decide.

Does Invoice create e-⁠invoices?

Yes — automatically the right file for your country, to the European standard EN 16931: ZUGFeRD and XRechnung for businesses in Germany, Factur-X for businesses in France.

Are the invoices legally compliant?

Yes. Every invoice carries the details your country’s law requires — in Germany those of § 14 UStG, in France every mandatory mention including the SIREN numbers — with sequential numbering, a VAT breakdown and a clean, archivable PDF.

Which countries does Invoice support?

Germany and France for now — each with its own rules: the mandatory details and tax notes on the invoice, and the e-invoice format of the country (ZUGFeRD and XRechnung in Germany, Factur-X in France). More countries are on the way. Your customers can be anywhere in the world, and documents go out in English, German or French.

Can I switch from my current invoicing program?

Yes. Continue your invoice numbering where your old program stopped, add your customers and products once, and send your next invoice from UNENO. There is no import from other programs yet, so you add a customer the first time you invoice them.

Do I need the whole platform to use Invoice?

No. You can use Invoice on its own and add the rest of the UNENO suite later — your account, data and login stay the same as you grow.

Your next invoice, in minutes.
