A project is finished. The client is happy. Everyone moves on to the next piece of work. Two weeks later, someone asks whether the invoice was sent. Nobody is entirely sure.
Unbilled work can be easy to miss when sales, delivery and finance sit in different places. Even when an invoice is created, a wrong reference or unclear payment terms can slow down the conversation that follows.
Connect the work to the invoice
Create a simple trigger for invoicing. It might be delivery confirmation, a completed milestone, an approved timesheet or a recurring billing date. The trigger should have an owner, and finance should know what evidence is needed.
If the service team says “we finished on Tuesday” but finance receives no record until Friday, that delay is worth examining. A small handover gap can become a cash collection issue.
Check what the customer will actually see
Before an invoice goes out, read it as if you were the customer. Does it show the correct legal or trading details where required? Is the service description recognisable? Are purchase-order references, agreed terms and contact details included?
The relevant requirements depend on the customer, contract and jurisdiction, so use your accountant’s or adviser’s guidance for any statutory invoice details.
An invoice that is technically complete but hard to understand often creates avoidable questions. Clear descriptions and agreed references help customers process it.
Give overdue invoices a steady follow-up rhythm
A sensible reminder process need not sound aggressive. Start with a friendly confirmation that the invoice arrived, then follow up near or after the due date according to the agreed terms. Keep the original invoice and payment information easy to access.
For example: “Hello, I’m checking whether invoice 1048 has reached the right person. Please let us know if you need a copy or any supporting details.”
That wording leaves room for a genuine problem, such as an incorrect reference or an invoice waiting in the wrong department.
Do not treat every overdue balance the same way
A disputed invoice, a customer who needs a corrected document and a customer who simply missed the payment date are different situations. Your accounts receivable report should ideally include short notes that explain the reason and next action.
It is also worth reviewing whether the invoice has already been paid but the receipt has not been allocated. Sending a reminder for an already-settled balance is an avoidable way to damage trust.
A small review can protect a lot of work
Once a week, compare completed work with invoices raised. Then review unpaid invoices by age, not just by total. Ask what is waiting on the customer and what is waiting on your own team.
