Check a fact where it is held.
Most checks happen afterwards: collect, reconcile, report, repeat. With mintBlue the check runs at the moment you decide, against rules agreed up front, and the organisation that holds the record returns only the field or the yes or no you need.

Organisations we have built with
mintBlue turned our nightmare of invoice exchanges into a dream of automation. Now we strive to make taxation less of a headache for everyone involved.

Where it is used
Tax checks and invoice checks need the same thing: an answer straight from the source, and proof of the check afterwards.
How it connects
From business event to proof in three steps
Your systems stay in place. mintBlue runs next to them and records each exchange, so an auditor or supervisor can check it.
- 01

A connector in your own environment
It runs next to your ERP, accounting software and other business systems, picks up the events you choose to share, such as an invoice or a payment, and signs them at the source.
- 02

An event stream between organisations
Signed events travel peer-to-peer to the parties entitled to them, encrypted for them, with no broker or hub you have to trust.
- 03

Certainty for every decision
Each check answers from the source at the moment you decide, so you act on verified facts. The tamper-evident audit trail lets an auditor or supervisor verify it afterwards, without asking for exports.

Where manual checks and ERP add-ons stop
Manual compliance means spreadsheets, email chains and quarterly audits. ERP add-ons work inside one organisation, not between organisations. Neither gives proof across organisations that a supervisor can check independently.
A check at the source removes that trade-off.
Manual processes and ERP add-ons
- Audit trails reconstructed after the fact from emails and file versions
- Multi-party verification impossible. Each party maintains their own version of events.
- Regulatory updates tracked manually. Legal team interprets, IT implements months later.
- Scales linearly: more suppliers means more headcount
mintBlue
- A tamper-evident audit trail, recorded as each exchange happens instead of rebuilt afterwards.
- Each party gets its answer straight from the source. Nobody pools the data.
- The checks are agreed once and applied to every exchange.
- Scales with volume, not headcount.
