Letting software act in the system that runs your business is the part that makes people hesitate, and rightly. So the limits here are structural. Reads come from a list written in advance and published. Writes are few, and never happen for a customer who has not been verified. Both levels of permission are re-checked at the moment of every single request, not once at setup.
Six checks, in order, with no bypass path.
Anything account specific waits until the customer proves who they are.
Two levels of permission, ours and yours, evaluated at the moment it runs.
A published lookup, or one of three documents it may raise. Never something it composed.
The answer crosses the tunnel. The database never does.
Every request, approved or refused, with its outcome and duration.
Health and reachability reported about every thirty seconds.
These are not permissions we withhold until you ask nicely.
Every lookup is pre-written with parameters filled in. An agent inventing a damaging query is not a risk we manage, it is a thing that cannot happen.
Posting payments, credit memos against the ledger and master data changes are out of reach and wait for their own approval design.
Nothing is deleted. A wrong order is cancelled, a wrong invoice is credited, and your ledger keeps the whole story.
