What business teams use today
Six modules for six
critical business workflows.
Invoices, suppliers, authorizations, product codes, documents, API audit – all under one roof, all with audit IDs.
Check suppliers
Company, role, signing authority – all checked against the register. A real membership instead of an Excel list.
Give authorization
Who's allowed to do what, from when, until when. Time-bound, revocable any time – with proof.
Keep products real
QR or NFC – one scan tells you: real product, right batch. Counterfeits stand out instantly.
Prove documents
Skip the PDF stacks – just a fingerprint. Counts as proof. Delete the PDFs.
API & audit trail
Webhooks, SDKs, audit export for your ERP, WMS or DMS. Plug-and-play for devs.
What you can roll out today
Three workflows,
three audit trails.
Every one of these workflows is live today. No waiting period, no rollout workshops – open the console and get started.
Supplier verification
New suppliers verified in 3 minutes, not 3 days.
Persons, companies, IBANs, authorizations – all in one path with proof. Onboarding without mail ping-pong, membership records replace spreadsheets.

One Trust Layer, three ways to use it.
Small businesses protect liquidity.
Bookkeeping and the owner decide together – no IT department needed. Trust App on the phone is enough.
Secure bank-account changes
Every new IBAN at a known supplier ends up in the Trust App – not silently in the banking interface.
