Order to invoice
Order confirmed
Accepted quotation becomes the source of truth
Invoice raised
Line items, tax treatment and terms carried over
Sent and logged
Delivered to the customer and recorded against the account
Due-date tracking
Every invoice has a status, not just a date
Why we built it
The order was already agreed — so why retype it?
An accepted quotation already contains everything an invoice needs: the customer, the scope, the amounts and the terms. Copying that into a separate document is duplicate work, and duplicate work is where mismatches appear.
Chasing was the second problem. Follow-up happened when someone had time, which meant older invoices quietly slipped down the list.
What it does
Issue, track, remind
The invoice is generated from the confirmed order, so the numbers match by construction. Once it is sent, the system holds a status against it — sent, due, overdue, part-paid, settled.
Reminders are scheduled from that status. Accounts only gets involved where a reminder has not worked and a conversation is actually required.

From confirmed order to collected payment

Due-date tracking

Reminders
Scheduled before and after the due date
Escalation list
Accounts sees only what needs a human call
What changed
The difference in day-to-day work
No re-entry
The invoice inherits the order, so the amounts on the two documents cannot drift apart.
Ageing is visible
Outstanding invoices are a live list rather than something assembled at month end.
Reminders are routine
Polite, scheduled reminders go out whether or not anyone is thinking about collections that week.
Escalation is deliberate
A call happens because the system flagged it, not because a customer happened to come to mind.
Cleaner conversations
When a customer is called, the full history of the invoice and its reminders is in front of the caller.
Feeds the dashboard
Collections status flows into the same daily view as enquiries, quotations and orders.
The client version of this system
Other internal systems
Collections should not depend on who remembered to call.
If invoicing and follow-up are still manual, that is usually the quickest place to return time and cash.
