From accepted quote to final invoice: the steps in between

The quote is signed. That is good news, but it is not payment. Between the client's yes and the final settlement there are several steps: the deposit, perhaps stage payments, extras agreed along the way, and the final invoice. Taking them in the right order keeps your cash flowing and your client clear on what they owe. Here is the sequence, with a worked example.

Step 1: the deposit invoice

If your quote asks for a deposit, issue a deposit invoice once the client pays it. It records the amount received against the signed quote and gives the client a proper document for their records.

The deposit is not a separate sale: it is an advance on the total price. That is why it must be deducted later. How to size the deposit is covered in our guide to asking for a deposit.

Step 2: stage payments on longer jobs

On a job that runs for several weeks, waiting until the end to be paid means financing the whole job yourself. Agree stage payments in the quote, each linked to a visible milestone:

Each stage gets its own invoice, referring to the quote. The client can check the milestone before paying, which makes payment faster.

Step 3: extras and changes

Clients often ask for more once work has started: an extra socket, a different tile, a shelf. Never do it on a verbal "go ahead".

1. 1Give the price for the extra.
2. 2Get written agreement: a signed change order or a short supplementary quote.
3. 3Add the extra as a separate line on the final invoice.

The same goes for problems you discover, like rotten joists or corroded pipes: explain, price, get approval, then do the work.

Step 4: the final invoice

The final invoice shows the whole picture:

• every line of the original quote;
• any agreed extras, as separate lines;
• the total price;
• the deposit and stage payments already received, deducted one by one;
• the balance due and its due date.

The client sees both the full cost of the job and what is left to pay. Nothing is hidden and nothing is double-counted.

Worked example

A kitchen refit quoted at 12,000 before tax, with a 30% deposit and one stage payment.

Amounts are before tax; apply your own tax rules.

Step 5: send it the day you finish

Every day between completion and the final invoice pushes back the day you are paid. Walk through the job with the client, check the snag list, and send the final invoice the same day, with a payment link if you can. If payment does not arrive on time, follow the steps in our guide to chasing late payers.

Common mistakes to avoid

A few slips cause most of the confusion between quote and payment:

• Forgetting to deduct the deposit. The client sees the full price again on the final invoice and thinks they are being charged twice. Always list each payment received, with its date.
• Mixing extras into existing lines. If the extra worktop is folded into the "worktops" line, the client cannot see what changed. A separate line, referring to the signed change order, answers the question before it is asked.
• Changing the quote after signature. The signed quote is the reference. Changes go through a change order, not a silent edit of the original.
• Waiting to invoice stages. A stage reached but not invoiced is money you are lending the client for free.
