Introduction
Japan’s invoicing rules have changed in ways that affect every company that buys from or sells to Japanese customers. Since October 1, 2023, the Qualified Invoice System (QIS) has determined whether buyers can claim input credits for Japanese consumption tax, and at the same time the country has been building a Peppol-based electronic invoicing standard. For finance teams using Microsoft Dynamics 365 Business Central, the question is practical: is your ERP set up to issue, receive, and keep invoices that meet these rules? This blog explains what changed and what to check.
This blog will cover the following points
- What the Qualified Invoice System requires
- How Japan’s e-invoicing model differs from other countries
- Peppol and JP PINT explained
- Record retention for electronic transactions
- What these changes mean for Business Central setup
- A practical checklist and how Sysamic can help
The Qualified Invoice System
The QIS was introduced to manage consumption tax input credits. Under the system, a buyer generally needs a valid qualified invoice from a registered issuer to claim the credit. Sellers must register as qualified invoice issuers with the National Tax Agency (NTA) and show their unique registration number on invoices, along with the applicable tax rate and the tax amount for each rate. The result is that invoice content now has direct financial consequences: a missing registration number or tax breakdown can cost your customer a tax credit, which quickly becomes your commercial problem.
Japan’s E-Invoicing Model
Many countries use real-time clearance, where tax authorities approve invoices before they are valid. Japan does not. Electronic invoicing is exchanged directly between businesses, and the tax authority reviews records afterward through audits. Adoption of structured e-invoicing remains voluntary rather than universally mandatory, although the government encourages it to cut paper handling and manual re-entry. Because there is no clearance step, accuracy at the moment of issue matters even more, since errors are found later, during a review.
Peppol and JP PINT
Japan joined the Peppol network, with the Digital Agency acting as its Peppol Authority, and adopted JP PINT, a Japanese specification based on the international Peppol BIS Billing 3.0 format. Invoices travel between certified Peppol access points in a decentralised model, so no central government platform is involved. For a company with trading partners that already use Peppol, supporting JP PINT reduces manual reconciliation and speeds up payment cycles. For others, it is an option to plan for rather than an immediate obligation.
Record Retention
Electronic transaction data must also be kept under Japan’s rules for electronic books and records, in a form that is complete, searchable, and readable. Printing PDFs and filing them is not always sufficient when the original transaction was electronic. Your retention approach should be agreed with your accountants and reviewed against current tax guidance.
What This Means for Business Central
Business Central can support these requirements, but only when it is configured with Japan in mind. Customer and vendor records need space for registration numbers, and your team needs a process to verify them. Sales invoice layouts must show the registration number and the correct tax rate and tax amount by rate. Consumption tax setup, including reduced-rate items, must be accurate so the calculated totals match the printed invoice. If you plan to exchange e-invoices, you also need to decide how JP PINT documents will be produced and received, usually through a Peppol access point and a connector or Marketplace app. Business Central’s standard E-Documents framework does not currently list Japan among its supported localizations, so this part typically needs a partner solution.
A Practical Checklist
First, confirm that your company’s registration number appears on every outgoing invoice. Second, validate the registration status of your vendors before claiming input credits. Third, review tax codes and rounding rules. Fourth, decide whether Peppol is right for your largest customers. Fifth, document your retention process.
Conclusion
Japan’s invoicing changes are less about a single deadline and more about getting everyday details right: registration numbers, tax breakdowns, structured data, and records. Companies that address these in their ERP now avoid credit disputes and audit surprises later.
