Since October 2023 Japan runs the qualified invoice system: to claim an input consumption tax credit, your supplier must be a registered invoice issuer. For unregistered suppliers, transitional relief lets you credit 80% of the input tax through September 2026, then only 50% from October 2026. That step down is the credit cliff. This Odoo 19 module verifies which suppliers are registered, flags the affected vendor bills and quantifies the credit you are about to lose in 2026, so you know your exposure before it hits your books.
The very screens you get in Odoo, the real thing.

The qualified invoice system changed the rule: holding the supplier's invoice is no longer enough, the supplier must be a registered issuer. And the transitional relief that cushioned unregistered suppliers shrinks in 2026. Working out how much that loss adds up to is anything but trivial by hand.
Some suppliers have a qualified issuer registration number and some don't. Without control inside the ERP, it is hard to know which part of your purchases earns full input consumption tax credit and which part doesn't.
The credit on unregistered suppliers drops from 80% to 50% in October 2026. If nobody quantifies that jump, you discover the cost only once you are already paying it, not while you can still react.
Cross-referencing bills, each supplier's registration status and the applicable rate in a spreadsheet is tedious and error-prone. And you have to redo it every period.
It doesn't file for you and doesn't replace your tax accountant in Japan. It does the concrete, useful part: it validates your suppliers' registration status, flags the affected bills and puts a number on the 2026 credit cliff across your real purchases.
Stores each supplier's official registration number (T-number) on their Odoo contact and validates their qualified issuer status, one by one or in bulk.
Automatically applies the correct credit rate (80%, 50% or 0%) based on the bill date and the supplier's registration status, no manual lookup per invoice.
A real-time compliance signal on every bill: the supplier's validation status and the applicable credit rate, right there without leaving the document.
Visualizes the input consumption tax credit at risk before and after the October 2026 step, with drill-down by supplier and by period.
Validates many suppliers in a single operation, with an audit trail behind every validation so nothing happens off the record.
Every validation and credit calculation is logged with timestamp, user and source, and exports to CSV or PDF for your accountant or auditor.
Company-scoped consumption tax settings and record rules, built for holdings and groups with more than one entity in Japan.
A scheduled cron watches your suppliers' status automatically and emails you when something changes or the cliff draws closer.
You install it in your own Odoo and work from the data you already have. No migration, no separate platform.
Add each supplier's registration number on their Odoo contact, then validate their qualified issuer status one by one or in bulk with the wizard.
On every vendor bill, the module applies the correct 80/50/0 credit rate from the bill date and supplier status, and shows a QII badge so the state is obvious.
The dashboard shows the consumption tax credit at risk before and after October 2026, broken down by supplier and period, with logs you can export for your accountant.
No subscription, no SaaS fee, no middleware. You buy it once on the Odoo App Store, install it in your own Odoo and it is yours.
A single purchase on the Odoo App Store. No recurring charges, ever.
You get the full source under the Odoo Proprietary License. Read it, audit it, adapt it to your setup.
Runs on Community and Enterprise across the three supported series, so you are covered whether you upgrade now or later.
When you have a question, you reach the person who wrote the code, not a ticket queue. Configuration help available if you need it.
FlexigoTech is Flexibles y Accesorios Gobe, S.L., based in Barcelona. Development is handled by a single developer, so when you ask something about Japan's qualified invoice or the credit cliff calculation you talk directly to the person who wrote the code, not to a salesperson or a first-line support desk forwarding tickets.
This is a native Odoo module, with no external platform to maintain and no extra SaaS fee. We don't invent reviews or customer stories: the tool validates your suppliers' registration status, flags the affected bills and quantifies the 2026 credit cliff. It doesn't file consumption tax returns and doesn't replace your tax accountant in Japan, and we tell you that before you buy, not after.
Japan's qualified invoice rarely travels alone. It usually shows up together with the need to organize purchasing, taxes and compliance inside a single Odoo.
Since October 2023, Japan's qualified invoice system (the invoice retention method) requires that, to claim an input consumption tax credit, your supplier be a registered invoice issuer with a registration number. For purchases from unregistered suppliers there is a transitional relief: 80% of the input tax was creditable through September 2026, dropping to 50% from October 2026. That step down is the credit cliff: from that date you lose more credit on every unregistered vendor.
The module records each vendor's official registration number (T-number) on their Odoo contact and flags which suppliers are registered qualified issuers and which are not, marking the affected bills. You see at a glance which part of your purchases earns full input consumption tax credit and which part falls under the transitional relief that shrinks in 2026.
No. The module works inside Odoo: it validates your suppliers' registration status and quantifies the credit you lose at the 2026 step. It does not file returns and does not replace your tax accountant in Japan. It gives you clean, organized figures so you can decide and your accountant can work from clear numbers.
Yes. It runs on both Odoo Community and Enterprise, and supports Odoo 17, 18 and 19. It builds on the standard Accounting/Invoicing app, so vendor bills and contacts work exactly as you already know them, with the qualified invoice logic layered on top.
It is a one-time payment of 49 EUR on the Odoo App Store, source code included under OPL-1. No subscription, no SaaS fee and no middleware. You install it in your own Odoo, and you get direct support from the developer who wrote it.
Yes. There is a live demo, a real Odoo 19 with the module installed and no sign-up (user demo, password flexigodemo), where you can see supplier validation and the 2026 credit cliff calculation. Once you are sure, you buy the license on the Odoo App Store, and if you need it we help you configure it and get the first calculation right.
The question is whether you discover that cost when it arrives or have it quantified beforehand inside Odoo. Tell us how you buy in Japan and we'll tell you straight whether the module fits.
