How this sheet is set
A text serif with the letter foot promoted to a ruled band across the sheet — the way a facture puts the issuer's particulars on the record.
The Window Letter layout
Dimensioned so the recipient's address falls inside the window of a standard envelope, with fold marks bleeding off the left edge and the issuer's particulars gathered into a foot block.
Who it suits
Invoices that are actually posted, and anywhere the printed letter is still the formal channel.
The voice of a document that will be filed: ruled or framed cells, formal serif or heavily structured sans type, and room for a signature and a stamp. It is a tone, not a legal status.
Modelled on the French facture
Modelled on the way a French facture arranges the page — a text serif throughout, and the letter foot promoted to a ruled band that carries the issuer's particulars across the sheet.
A tradition tag describes layout lineage and nothing more. It is not a compliance claim. The template prints exactly the facts you type: there are no per-line tax rates and no state-issued identifiers in the document model, and nothing is validated, registered or checksummed. Whether a given document satisfies a particular country's requirements is between you and your accountant.
What it prints
Every template in the library prints the same set of facts — a template that dropped one would fail the library’s own contract test. What changes between them is where the facts sit and how they are set.
- Issuer and recipient, each with an address, an optional contact line, and a tax label and number you write yourself.
- Invoice number, issue date, service period, payment terms or an explicit due date, and the date of the service agreement.
- Your own references — purchase order, contract, cost centre — labelled the way your client labels them.
- Line items with a quantity, an optional unit, an optional period, a rate and an amount.
- A note field, and full banking details with an optional payment reference.
Anything you leave empty prints nothing at all — no blank labels, no placeholder rows.
