How to Invoice a Deposit and Stage Payments

The wrong way, and why it feels right

The instinct is to invoice the deposit, then invoice the balance. Two jobs, two invoices, clean. It is not clean:

One job now has two invoice numbers, so your records show two sales
Neither invoice shows the full contracted amount
If the job is cancelled halfway, nothing reconciles
At year end you have to remember which pairs belong together

The way that holds up

One invoice for the whole job, showing the full amount
Record each payment against that invoice as it arrives
Issue a receipt for each payment, showing the updated balance

One invoice number, one running balance, one place to look when the customer asks what is outstanding.

What it looks like in practice

Date	Document	Amount	Balance
5 Jan	INV-0182 — full job	RM1,175.94	RM1,175.94
5 Jan	RCP-0091 — deposit	RM500.00	RM675.94
2 Feb	RCP-0104 — final	RM675.94	RM0.00

Three documents, one thread. The customer can reconcile it themselves without calling you.

The balance line is what does the work. An invoice that says "TOTAL RM1,175.94" and nothing else invites the customer to pay the full amount again. An invoice that says "PAID RM500.00 / BALANCE DUE RM675.94" cannot be misread.

How much deposit to ask for

There is no rule, but there is a principle: the deposit should cover what you cannot recover if the customer walks away.

Goods you buy in specifically — deposit at least the cost of the goods
Custom or made-to-order work — 30–50% is common, because it cannot be resold
Labour-only jobs — often smaller, since your exposure is time rather than cash
New customer, any job — a deposit is also a filter; someone unwilling to commit anything is telling you something

Try the payment flow

Record a part payment on an invoice, watch the balance recalculate, and generate a receipt linked to the original invoice number.

Stage payments on longer jobs

For work that runs over weeks, tie each stage to something the customer can see:

Stage	Trigger	Typical share
1	On acceptance of quotation	Deposit
2	Materials delivered to site	Progress
3	Work complete, before handover	Balance

Triggers tied to visible milestones are much easier to collect than dates on a calendar. "The materials are on site" is not arguable; "it is the 15th" is.

Put the terms on the quotation, not the invoice

By the time you send an invoice, the payment structure should already be agreed. State it on the quotation — deposit amount, what triggers each stage, and what happens if the job is cancelled. Then the invoice simply follows what was accepted.

Three things to avoid

Taking a deposit with no document at all. Cash in hand and nothing written is how the argument starts.
Issuing the receipt before the money clears. A cheque that bounces after you have issued a receipt is a difficult conversation.
Letting the balance go unrecorded. If the second payment never gets logged, your own records say the job is still owing — and eventually you will chase a customer who already paid.
