Who can do what, what is written down when they do it, and where your data actually lives.
Everyone gets their own login. Not a shared password on a terminal — every receipt, batch and delivery carries the person who recorded it, which is also what makes the quality records worth anything.
Access is controlled in two layers. Which screens a person lands on, and — separately and more importantly — which documents they may open, create or submit. A picker sees picking, not the ledger, and cannot reach it by typing an address either.
Roles and rights come out of your own structure and are configured during implementation, then held in the system so an update cannot quietly undo them.
Any document can be put behind an approval route: who may move it, at what value, and what happens next. Batch release, credit and purchase approval all use the same mechanism, so there is one thing to understand rather than several.
Intacct is the golden source, and that is a design rule rather than a preference. Anything Intacct can hold is held there — items, customers, suppliers, warehouses, bins, units, orders, costs. Fuse reads them and never writes them back, so there is no second copy for anyone to edit.
Fuse keeps only what Intacct has nowhere to put: the operational record of how the work was done. Who picked which lot, what the inspection measured and on which instrument, what the shop floor scanned, what a works order actually consumed — plus the log of every message sent to Intacct and what came back.
If Fuse were switched off tomorrow, your financial record would be complete and correct in Intacct. What you would lose is the operational detail behind it, not the books.
Where the quality module is switched on, these are produced as a by-product of doing the work rather than written up afterwards:
Certification is awarded to your organisation, against your processes and your people as well as your system. Fuse provides the evidence; you run the system.
Nothing to defend at the audit: Intacct remains the system of record, every write is logged in full, and the log cannot be edited by anyone.
