Art. 226

Numbering is sequential and gapless, the VAT rate is the one the order actually carried, and the figures are the order’s own — not retyped from it.

Article 226 lists what a valid EU invoice must carry. Every one of those fields comes from data Profflow already holds, so the invoice and the dashboard cannot disagree about what the sale was.

01 / The case for it

Every retyped figure is a figure that can be wrong.

Without it

An invoice assembled by hand from a dashboard is a second copy of numbers that already exist, with a second chance to be wrong and no way to trace which one is right. And in Europe an invoice that is missing a required field is not a document, it is a problem.

What Profflow does

Built from the model, not from a spreadsheet.

Client and line details are entered once; totals, tax and numbering come from the same figures the dashboard renders. The series is sequential with no gaps, which is the part that has to survive review.

02 / Worth understanding

Why an invoice is a compliance document

  • A gap in the numbering is a question from an auditor

    Invoice numbers have to be sequential and unbroken. Generating them from the orders themselves, in the order the orders exist, means the sequence cannot develop a hole because somebody deleted a draft.

  • Article 226 is a list, and the list is not optional

    The EU VAT Directive sets out what an invoice must carry: the date, a unique number, both parties’ details, the VAT identification number where it applies, the rate, the taxable amount and the tax. A document missing one of them is not a smaller document, it is not an invoice.

  • The invoice and the profit figure are the same data

    Because both are built from the same order, the total on a customer’s invoice and the revenue in your month cannot disagree. Every product that keeps them in separate systems eventually finds out that they do.

03 / What it lets you do

What follows from getting Invoices right.

[ Asked of the figures ]

Is invoice #0042 compliant for a B2B EU client?

Yes — it carries the sequential number, both VAT IDs, the 22% breakdown and the Article 226 fields. It is ready to send as a branded PDF.

How Profflow reasons

06 / How the figure is kept honest

The same four rules,
on every screen.

  • Read-only, on every plan

    Profflow observes the accounts it is connected to. It does not write an order, a price, a campaign or a payout back to any of them.

  • Measured stays measured

    A charge read from an account is labelled measured. Anything modelled — a forecast, a projection, a filled gap — is labelled as such on the screen it appears on.

  • Every figure opens

    Follow any number to the dated rows underneath it. A figure nobody can check is a figure nobody acts on.

  • You approve

    The product prepares a decision and shows the evidence. Nothing consequential happens until you say so.
