Invoicing was never this easy.
Invoice, get paid and keep your expenses without learning accounting. It is the app we invoice with ourselves.
No setup fee. Monthly, no lock-in.
The photo, and that is it. The expense writes itself.
You photograph the receipt and the AI reads supplier, tax ID, date, net, VAT, total, line items and the accounting code it belongs to. If the supplier is not on your list, it creates it from what it read.
We do not give you an accuracy figure, because the model does not produce one: we tell you which fields it read and which it did not, and we check the maths adds up.
It reads photos and normal PDFs. A scanned PDF, the kind that is a photo inside, not yet.
On a phone it opens the camera straight away.
Connect your bank. Payments mark themselves.
It happens on your bank's own site, with your usual credentials, and takes a minute. When a client pays you, Gufi finds the invoice and marks it paid.
The usual ones, over open banking.
Read only: Gufi can see your movements, never move your money.
Touch it. And watch it change.
On the left, the form you get inside Gufi. On the right, the invoice that comes out of it. Change a quantity, a price or a VAT rate and watch it recalculate in front of you.
New issued invoice
The data is made up and the IBAN is all zeros: a real invoice on a public page would be a leak.
You send it to be signed. It comes back as an invoice.
Your client opens a link, signs with a finger and that is that. The invoice comes out of that signature with its numbering and its legal mentions, and when the money lands in the bank it marks itself.
Valid 30 days · Payment 30 days from issue
Ready for VERI*FACTU. And we tell you exactly for what.
Every invoice is sealed and chained: hash, QR and a chain between records. What we do NOT do yet is file them with the Spanish tax agency. And worth knowing: the obligation is deferred to October 2028.
We would rather tell you than have you find out.
The first thing you see. Who has not paid you.
Not a dashboard you have to learn: the oldest debt at the top, with its button to chase it, and below it what you have invoiced, collected and spent this month.
And you carry it with you. The same app, in your pocket.
The same app on the phone: you check how the month is going, photograph the receipt from lunch and issue an invoice while the coffee lands. It is not a cut-down version.
How the month is going, on opening.
Photograph the receipt, expense done.
A new invoice, in three steps.
The two on the right are real phone screens. The summary one is drawn with example data: the real one carried clients and amounts that are not ours.
Six documents. Every one with its numbering and its trail.
These are not six Word templates with the logo swapped: each has its series, its consecutive numbering guaranteed by the database and its link to the others. The quote knows which invoice it ended up in, and the credit note knows which one it corrects.
Issued invoice
With consecutive numbering guaranteed by the database, its legal mentions and its hash.
Credit note
Points at the invoice it corrects and leaves it traced. Nothing gets deleted: it gets corrected, which is what the law asks for.
Quote
Sent as a link, your client signs it with a finger, and the invoice comes out of that signature without retyping anything.
Recurring
Monthly, quarterly, yearly or last day of the month. It issues itself and, unpaid, the dunning chain claims after the due date.
Received invoice
The photo of the receipt becomes an expense, with its supplier and accounting code, ready for your accountant's export.
Signed contract
Signed by both parties, with its date and its trail, and hooked to the invoices that come out of it.
What is not there —delivery notes, pro formas, sales orders— is not on this list, even though others have them. Promising a screen that does not exist is expensive exactly once.
What stops being done by hand. In three businesses with nothing in common.
Gufi invoices with this very app, every day. It is not a demo dressed up to be shown.
Every tenancy issues its invoice on the day it is due.
Monthly and in bulk, with the due date set. And if someone does not pay, the dunning chain claims on its own after the due date.
The quote gets signed and turns into an invoice.
Your client accepts and signs online, printing nothing, and the invoice comes out of that with its numbering and legal mentions.
The van receipts stop being an envelope.
Photograph the receipt and the expense is done, with its accounting code, ready for your accountant to take in the A3 export.
These are three things the app does, in the product's voice. When we have the words of the people who use it, they will go here signed.
No setup fee. No lock-in.
We do not charge to get you going, and it is a monthly fee you can drop whenever you like. We tell you the figure when we talk, looking at what you actually need.
Shall we look at it with your invoices?
We show you how yours would look, with your own invoices in front of us.
No setup fee. Monthly, no lock-in.
