The problem

The bottleneck isn't the work. It's the invoice.

You finish the day with six jobs done. Two hours to go: fill in each job's work order, tally the materials, open Excel, write the invoice, remember the tax ID, send it. The hardest invoice to get paid is the one you never get round to sending.

  • Unstructured Excel, copy-and-paste by hand.
  • Customer details scattered across notes, messages and diaries.
  • Drafts left half-done and forgotten.
  • Materials that leave your stock but never make the invoice.
  • Tax mistakes you only discover at the end of the quarter.

How it works

Three steps.
Five minutes at the end of the day.

You do the work. OfiFlow handles the paperwork.

01 · SPEAK

Tell it what you did, out loud.

Customer, address, what you did, materials used and hours. Just as you would tell a workmate. The AI transcribes and identifies it all.

02 · REVIEW

The system proposes the lines.
You approve them.

Materials are looked up in your catalogue. Prices come from your own rates. You confirm or correct. Nothing is invoiced without your say-so.

What's included

Built for your trade.
No ERP frills.

Voice capture, online and offline

Record with no signal — it syncs when you are back in range. No recordings lost in the attic of a job site.

AI that knows your catalogue

Say "the K12 tap" and the AI finds it in your rates. If it does not exist, it is left "unassigned" for you to decide.

Legal invoices + correctives

Sequential numbering, VAT by rate, immutable snapshot. Make a mistake? Issue a corrective invoice in one tap.

Stock with every work order

Invoice a material and it is deducted from your catalogue. Automatic alerts when something runs low.

Veri*Factu ready

Hash, previous-record chain, QR. When the Spanish tax agency requires it for your volume, you are already wired. Nothing to migrate.

Import your current Excel

Upload customers and rates from your Excel. The AI maps the columns and you confirm. Takes less time than writing one invoice.

Send the work order to your customer

A PDF delivery note — with or without prices — straight to WhatsApp, messages or email. Provisional, non-binding: the invoice is separate.

One job, several days

Attach visits with their audio each time you go back to the site. When you finish, one single invoice with everything.

Know what's still unpaid

Every invoice moves from pending to collected to settled with its receipt. KPIs for the month invoiced and collected, at a glance.

Your data is yours

Export everything as a ZIP whenever you like — transcripts, work orders, customers, invoices — and decide how long we keep your audio. Hosted in the EU.

Common questions

What we get asked before people start.

What if the AI doesn't understand my audio properly?

The system shows you exactly what it transcribed and which lines it could not interpret. You correct them by hand before anything becomes an invoice. Nothing is issued without your approval — the rule is "AI proposes, you validate, the system invoices".

Are my invoices legally valid in Spain?

Yes. Sequential numbering, immutable snapshot, VAT rates, full fiscal details, a PDF ready to send. We are Veri*Factu-ready for when the tax agency requires it for your volume — the hash and the chain are already generated on every issuance.

What if I make a mistake on an issued invoice?

Issued invoices are immutable by law. If you need to correct one, you issue a corrective invoice (full cancellation, amount correction or customer details correction). It is built into the flow: open the invoice, pick the corrective type, and the system generates the sequential document.

Does it work on site without internet?

Yes for recording and editing drafts. Audio queues up and uploads when you are back in range. The only thing you cannot do offline is issue final invoices — they allocate a serial number and require atomicity.

Can I import my current Excel of customers and rates?

Yes. Onboarding has three paths: upload your Excel (the AI maps the columns and you confirm), start from a typical rate sheet for your trade and adjust it, or export from another program (Holded, Quipu, FacturaDirecta) and upload it here.

What happens to my data if I stop paying?

Nothing is deleted. Issued invoices stay available for download and consultation forever, even if you drop to Free or cancel: your fiscal history is yours by law. Your work orders, customers and catalogue stay too. If you exceed a limit of the new plan, what you already have stays as it is; you just can’t create more (audio, invoices or items) until next month or until you are back under the limit.

How long until I am up and running?

Under 5 minutes from signup to your first work order. Tax ID + trading name, choose how to load your catalogue (import / preload / skip), and you can start recording.
