Sage Intacct keeps the books. Fuse runs the floor.
An operational layer that sits beside Intacct and posts every stock and production movement into it as it happens — live, costed, and rejected by Intacct if Intacct doesn't like it.
“Intacct already does inventory. What is this for?”
It does, and Fuse doesn't replace any of it. The gap Fuse fills is not accounting — it's the shop floor.
A manufacturer's day is made of actions Intacct was never meant to host: a supervisor closing off a production run, a storeman moving a pallet between warehouses, an operator issuing components into work in progress. Those people don't have Intacct logins, shouldn't have Intacct logins, and would be slow and dangerous in Intacct if they did.
Fuse gives them screens shaped for the job — at a desk or on a tablet at the machine. Every action they take lands in Intacct the moment they take it, with the quantities, the valuation and the audit trail the finance team expects to find there.
No overnight file. No summary journal. No suspense account. No month-end reconciliation between two stock figures.
Four commitments govern the whole integration. Between them they remove most of the questions a consultant would otherwise have to ask.
Intacct posts first
If Intacct rejects the post, the Fuse transaction does not stand. There is no half-committed state and no queue of failures to clear.
Fuse never invents a value
It records the cost Intacct accepted. Where Intacct holds no cost, Fuse refuses and reports rather than substituting a plausible number.
Live, never batched
Movements post as they happen. Nothing is held for an overnight run, and no journal is summarised on the way through.
Masters flow one way
Accounts, customers, suppliers, items, warehouses, bins, units, entities and tax schedules are mirrored from Intacct and read-only in Fuse.
What a client's people do with it
The working set in the first implementation is production against a bill of materials, issuing components to work in progress, warehouse-to-warehouse transfers, and the stock views the floor and the buyer ask for — on the desk, and on a shop-floor screen built for a scan, a quantity and one button.
That is a deliberately narrow slice of what the platform carries. Routings, job cards, capacity, quality inspection, maintenance, traceability and planning all sit behind it, and none of them change who does the accounting.
Intacct is the golden source and always does the accounting. There is no option and no configuration that changes it.
Document 02 sets out the full capability, grouped by what turning each part on actually costs.
The first implementation is a rubber products manufacturer, running against their live Intacct company and in final user acceptance testing.
The masters mirror, the posting layer, the audit log and the reversal path are all built and proven — real production runs and transfers, with real Intacct document numbers behind them.
Fuse is now being opened to Sage consultants who sell and support Intacct. This pack is an introduction to the product, not a commercial proposal: how a partnership works and where the support line sits are conversations to have next.
Your client keeps Intacct as the system of record, and gains a manufacturing floor that feeds it in real time.
Fuse never asks them to trust two sets of numbers, because there is only ever one.
