pint-jp — no obligation in law

No Japanese statute obliges a business to issue or accept an electronic invoice. 消費税法 art. 57-4(5) lets a qualified invoice issuer provide the particulars of a qualified invoice as an electromagnetic record instead of paper, which is what a Peppol invoice is. The Digital Agency is the Japan Peppol Authority and maintains JP PINT, the Japanese specification of the Peppol International model (Peppol BIS Standard Invoice JP PINT 1.1.3, customization urn:peppol:pint:billing-1@jp-1). Its tax categories are S (standard), AA (lower rate), E, G and O. A party is addressed by its 法人番号 (corporate number, EAS 0188), as the JP PINT examples show, and the seller's tax registration identifier is the registration number of the qualified invoice issuer (EAS 0221), which the NTA's register publishes as T followed by thirteen digits. JP PINT asks the tax per rate to be rounded to the yen, between the floor and the ceiling, and leaves the direction to the issuer.

Free, and operated

Where the open core stops.

The line is operational, not functional. Everything that keeps working on its own is open core; what needs credentials, a certificate or a channel somebody keeps running is the hosted edition.

JP-CT-KAKUTEIdeclaration

Free, for everComputed from the ledger, frozen box by box, filed by hand on the administration’s portal, and what it owes is carried to 2160. The deposit number and the administration’s own words come back into your own database.

OperatedTransmission: the credentials, the certificate and a channel somebody keeps running. The return stays yours.

pint-jpeinvoicing

Free, for everAn invoice is written and validated as pint-jp by a brick of packages/formats, and read back the same way.

OperatedSending and receiving over Peppol: a certified access point and a certificate.
