Watch your suppliers and customers — we email you only when something changes

Paste the invoice registration numbers (T-numbers) or corporate numbers of the companies you deal with. Every Monday morning we compare them with the official registries and email you only if something changed: invoice registration revoked or expired (you would lose the input-tax credit on their invoices), a name change, a head-office move, a closed registry record (dissolution / merger), a new government contract award, a new licence or a new subsidy.

Privacy: your email address is the only personal data we store, used solely for these notifications, and deleted the moment you delete the list. Sources: NTA invoice registry & corporate-number registry (daily), 調達ポータル awards (daily), gBizINFO licences and subsidies (monthly).
