International.EInvoicing.Countries.Greece

What Greek electronic invoicing adds on top of the norms.

Greece exchanges Peppol BIS Billing, with Greek rules that travel inside the Peppol rule set — and they ask for two things nothing else in this library does.

The invoice number is a compound key. GR-R-001 is fatal: when the supplier is Greek, BT-1 is six segments separated by |, and every one of them is checked against the rest of the document.

string number = GrInvoiceNumber.For(
    supplierTaxIdentifier: "100000003",     // must satisfy its checksum and match the seller's VAT number
    issueDate: new DateOnly(2026, 9, 1),    // must be the same date as BT-2, written DD/MM/YYYY
    branch: 0,
    documentType: "1.1",                    // one of six myDATA codes
    series: "A",
    number: "0001");

An ordinary invoice number is rejected outright, and a hand-built string fails for reasons that are hard to read off a validation report — so For checks each part where it can, and names the rule when it refuses.

The AFM has a checksum of its own. The first eight digits are weighted by descending powers of two — 256, 128, 64, 32, 16, 8, 4, 2 — and the ninth is the sum modulo 11, modulo 10. GrTaxIdentifier verifies it, and writes the number in scheme 9933.

And one MARK number. GR-R-004-1 requires exactly one additional document reference described as ##M.AR.K##, carrying the myDATA registration:

invoice.AdditionalDocuments.Add(new AdditionalDocument
{
    Identifier = "400001234567890",
    Description = "##M.AR.K##",
});

myDATA itself is out of scope. Reporting every invoice to the platform is a transmission, not a document, and this library performs no network I/O. What it does is produce the document myDATA expects to hear about.

The Greek rules are inside the Peppol rule set: build/fetch-specs.sh peppol, then AddPeppolRulesFrom(...).
