The apps

Core apps are what a trade runs on. Extra apps are what a business adds on top of them, and the subscription each person holds sets how many apps that person may use in all — one allowance, whichever kind they are.

On every seat

The one app that is not counted. It is on every person’s seat on every tier, it never uses up an allowance, and every other app reads its names and addresses from it rather than keeping a second list.

What joins up, and what that means

Each trade app keeps the money that is its own work — a hotel’s folios and cashiering, a till’s sales, returns and shifts, a travel file’s invoices and receipts, a payroll run — and none of them keeps a second set of books beside it. Invoices, payments, expenses and tax for the business as a whole are kept in one place: Accounting.

Add Accounting and, once its chart of accounts is set up, that money — from Hotel, POS, Travel and payroll — is posted into one ledger. This is the part worth being exact about. The apps do not keep figures of their own and reconcile them afterwards — there is one set of figures, and the trade apps write into it. Two systems that sync can disagree; this cannot.

Those four links are on by default for every company that has Accounting and the app. Each starts with a posting map filled in from your own chart of accounts, and your accountant can re-point any line of it. If Accounting is removed, the links it switched on are switched off again, so no app goes on feeding a ledger nobody can open.

Underneath, an invoice, a bill, a receipt and a payment are each declared once, in one place, and every app speaks that same shape. Money travels as a whole number of minor units with its own currency and its own precision attached — so a three-decimal dinar is a three-decimal dinar on every screen it passes through, rather than something a formatter has to guess at.
