The risk

With e-invoicing, every mistake becomes visible.

Whatever the AGT can cross-check, you need to see first. Three blind spots come up in every finance team we work with.

  1. Revoked software

    Your supplier issues invoices with software whose certification has been withdrawn. The invoice looks normal. It no longer is.

  2. An error that gets cross-checked

    A wrong NIF, a skipped series number, miscalculated IVA: the gap shows up in a cross-check, often months later.

  3. No proof of the check

    Without a written trail, you cannot show the auditor that the invoice was checked, by whom or when.

The rules

Eight checks on every invoice, in seconds.

The rules follow the AGT e-invoicing regime and are updated when it changes. There is nothing for you to configure.

How it works

From invoice received to proof on file.

  1. 01 · Import

    Upload your invoices

    PDF, XML, photo or an export from your software. Suppliers and customers, in one place.

  2. 02 · Check

    CYTO applies the eight rules

    AI reads every field, then each rule returns a verdict: compliant, to check or non-compliant.

  3. 03 · Fix

    Every issue is explained

    The field at fault, the expected value, the gap in figures. Assign it to the right person.

  4. 04 · Prove

    The trail stays

    Every check is timestamped and can be exported for your accountant or auditor.

The audit trail

Every check leaves a trail.

Who imported, what CYTO found, who fixed it, when the invoice became compliant again. On audit day, you export the file instead of rebuilding it.

“What impressed me the most was the fact that it can even detect whether the software used for issuing the invoice is still valid or has been discontinued. Your product is very robust for the Angolan market.”

Miguel CostaFinance Manager

“Given the notification of non-compliance of several software solutions, the creation of a testing software is a great added value.”

Questions

Before you start.

No. CYTO sits on top of your existing software. It checks what you issue and what you receive, without changing the way you invoice.

Check your next invoice before the AGT does.
