Glazier Deposit Invoice: Control Made-to-Measure Glass Jobs

The supplier is waiting for the order. The glazier deposit invoice has gone to the customer, but the final measure and glass specification are not signed off.

Stop there. A deposit request does not approve fabrication. Freeze the opening, settle the UK approval questions, record cleared funds and check the purchase order before you commit to made-to-measure glass.

Freeze the opening before requesting the deposit

Inspect the opening before you ask for money. Complete the final measure, specification, access plan, exclusions and full selling price before issuing the deposit request.

Use the glazier window replacement quote guide to control the survey and pricing work. This article starts at the next decision: whether the job is ready for a glass order deposit and supplier release.

Give every opening a permanent reference

Assign a permanent opening reference during the survey. Carry it through the quote, fabrication sheet, deposit request, supplier purchase order, delivery record and installation record.

Do not write “upstairs window” when similar sealed units are coming to site. Use a stable reference that the person measuring, the supplier and the installer can all follow.

Put a temporary label on the opening if that helps on site. Put the same reference on drawings, templates and photographs. The label must survive staff changes and separate visits.

Record the final measure and its owner

Write down who supplied the dimensions. It could be your surveyor, the customer, a drawing, a template or another tradesperson. Do not leave the source unclear.

Mark whether the opening was ready for final measure. Record frame condition, tolerances, orientation and anything that could alter the finished size. If the opening still needs structural, frame or finishing work, hold fabrication.

The customer may pay before a difference is found. Payment does not settle the dimension. If a recheck differs from the final measure recorded for the deposit request, stop the order and correct the fabrication record.

Complete the supplier-ready specification

The fabrication sheet carries the technical instructions. Record the dimensions, glass build-up, treatment, tint, pattern, coating and orientation where they affect the unit.

Add edge work, holes, notches, cut-outs, hardware preparation and quantity. Where the opening demands a safety, thermal, fire, acoustic or other performance classification, record the classification or standard reference confirmed for that job and the person who checked it. Attach the controlled drawing or template. Give the fabrication record its own reference and revision status.

Keep the surrounding work clear as well. State who handles removal, disposal, access equipment, lifting, frames, channels, seals, trims, protection and making good. Write exclusions beside the scope rather than relying on a conversation.

Separate customer choices from the technical check

Ask the customer to approve the choices they can see. Finish. Pattern. Tint. Hardware style. Opening reference.

Complete the technical check separately. Confirm the final dimensions, glass designation, required performance classification, orientation, treatments, edge work, holes and hardware preparation. Record who completed that check.

The accepted quote should state what must happen before fabrication can start. Keep cancellation, refund and fabrication-risk wording in that agreement, not in an email written after the deposit arrives.

Check the installation address before releasing the order

Building approval and tax are separate questions. Ask the body responsible for each question, record the opening or scope checked, and mark the order held or released.

For an installation in England, ask building control (opens in a new tab) whether building regulations approval or inspection applies to that address and scope. Record who answered, what work was checked and whether fabrication can proceed.

For an installation in Wales, use the Welsh Government’s building regulations approval guidance (opens in a new tab) and ask the building control body responsible for the address what approval or inspection is required before the glass is ordered.

For an installation in Scotland, ask the relevant local authority verifier about the Scottish building standards route. Start with the official building warrant guidance (opens in a new tab), then record the verifier, the scope checked and the result.

For an installation in Northern Ireland, use the official building regulations guidance (opens in a new tab) and ask the council building control service what must be approved or inspected before the order can proceed.

If the scope raises planning permission or listed-building questions, ask the local planning authority for the installation address before ordering. Find the council through the official council finder for England and Wales (opens in a new tab), Scotland (opens in a new tab) or Northern Ireland (opens in a new tab). Record the decision and complete any conditions that must be met before ordering.

Ask HMRC about VAT (opens in a new tab) before deciding how the deposit, stage request and final invoice should be treated. Keep the tax answer with the customer account so the documents follow the same treatment.

If the contract raises a Construction Industry Scheme question, check the work and payment with HMRC’s CIS guidance (opens in a new tab) or your accountant. Do not assume every glazing contract is handled in the same way.

Open the cost record when the quote is accepted

Create the job-cost record when the customer accepts the quote. Add supplier purchase orders, freight, labour, hardware and variation costs as they arrive. Close the record only after the final supplier and labour entries are in.

Invoices tell you what the customer was charged. They do not tell you what the job cost.

Enter the actual labour, glass, frames, hardware, seals, freight, access, disposal and other direct costs. Add the overhead treatment used by your business. Keep this cost tracking attached to the same job as the quote and invoices.

On the Oak Street worked example, the job cost was 850 against the original quote of 1,105. Profit on that original quoted work was 1,105 − 850 = 255. Margin was 255 ÷ 1,105 ≈ 23%, while markup was 255 ÷ 850 = 30%.

The cost of the 160 variation was not given. Do not combine the 1,265 final invoice with the 850 cost or claim a profit figure for the changed work.

Calculate the glass order deposit from real commitments

Build the complete selling price before splitting it into payment stages. Price the job from labour, glass, frames, hardware, seals, consumables, freight, access, disposal and other direct costs. Add overhead and markup to reach the selling price.

Use your supplier quotations and labour plan. The job pricing framework shows how to keep labour, materials, overhead and markup separate.

Use this worksheet with your own figures:

Start with everything the business will commit before installation. Subtract each cancellable, returnable, reusable or credited amount once.

Ask the supplier what can be cancelled, returned, credited or reused after release. Keep the answer with the purchase order rather than relying on memory.

The worksheet gives you the commitment at risk. The proposed glazier deposit invoice amount must still match the accepted payment terms and the VAT treatment confirmed for the job. Do not select an arbitrary percentage because it was used on another contract.

Future installation labour does not automatically belong in the deposit. Include a commitment only when the accepted agreement and the actual job plan support it.

State how the deposit will be treated. Cleared payment should be credited once against the accepted contract price. It must not appear later as another sale added on top of that price.

Build a glazier deposit invoice that points back to the job

Before issuing a glazier deposit invoice, establish what document you are sending. A payment request, pro-forma document and VAT invoice do different jobs. Confirm the correct treatment before taking payment.

Check HMRC’s guidance on when VAT must be charged (opens in a new tab) and what a VAT invoice must contain (opens in a new tab). Record the deposit tax point and required invoice details under the VAT treatment confirmed for your business and this transaction.

Reference the approved fabrication sheet rather than copying every technical detail onto the invoice. Dimensions, holes, notches, performance classifications and edge work belong on the controlled supplier record.

Copy-ready deposit document template

For a consumer job, check current government guidance before drafting cancellation or non-refundable-deposit terms. This matters where goods are made to measure or the agreement is made at the customer’s home. Use the government guidance on contracts made away from business premises (opens in a new tab) and the Competition and Markets Authority guidance on unfair contract terms (opens in a new tab), then have your terms reviewed for the work you sell.

Save a separate payment record when the money arrives. Record the amount received, payment reference, receipt date and the invoice it settles. “Sent” and “pending” do not mean paid.

Keep the deposit request and fabrication release separate

Use separate gates. Do not let payment stand in for a technical decision.

• Issue the request only after the quote is accepted, the final measure is recorded, the fabrication revision is identified and the customer choices are approved.
• Mark the payment gate complete only when the funds have cleared and the receipt is attached to the job.
• Mark the technical gate complete only when the named checker has approved the dimensions, glass designation, performance classification and fabrication details.
• Release fabrication only when those gates are complete, the authority checks allow the order to proceed and the supplier purchase order matches the approved fabrication revision.

Use this compact order-release card on the next job:

Opening reference: [ ]
Final measure completed by: [ ]
Fabrication sheet and revision: [ ]
Customer selection approval: [ ]
Authority asked and scope checked: [ ]
Recorded result: [HOLD / RELEASE]
Deposit payment status: [Pending / Cleared]
Technical approval completed by: [ ]
Supplier purchase order checked by: [ ]
Final order decision: [HOLD / RELEASE]
Release authorised by and date: [ ]

If an emergency make-safe visit came first, keep its work order and charges separate. The emergency make-safe to replacement process shows how to hand that job into the replacement stage without burying the first visit in the glass deposit.

Match every delivered unit before fitting it

Check the delivery against the supplier purchase order and opening schedule before installation. Read the labels. Check the quantity, dimensions, specification and visible condition.

Record damage, missing units and specification differences before fitting. Photograph labels where useful and keep the delivery note with the job.

During installation, mark each opening as fitted, held or incomplete. Record trims, making good, access work and other tasks left for a return visit.

Issue a glazing progress invoice only when the evidence matches the contract’s named trigger. Record the matched opening references, whether each unit was delivered or fitted, any defects and all work still held. If the agreement ties payment to installation, do not describe glass sitting at your workshop as installed work.

Keep incomplete work separate from disputed work. A missing trim may leave a return visit. A disputed specification needs its own decision and record.

Record changed work as a variation

Removal can expose frame damage or surrounding work that was excluded from the accepted quote. Stop before carrying out the extra work.

Describe the condition. State the labour, materials and effect on the programme. Price the change and get approval. Then complete it.

Keep the variation separate from the original quote and deposit. Do not hide an extra inside a larger final balance or rewrite the original quotation after the customer has accepted it.

Worked example: Oak Street

This is the house electrical example, shown in sample currency units rather than as a rate card.

R. Chen accepted Quote Q-1847 for 1,105 at 14 Oak Street. The work was a bathroom exhaust fan, ducted through the roof, and four LED downlights. The ceiling was lined, and the quote excluded chasing.

Extra cable and chasing were approved on site as a 160 variation. Invoice INV-1847 was therefore 1,265. The original quote stayed at 1,105. The approved variation explained the difference.

Use the same document control on a glazing job. If an exposed frame needs excluded work, write the variation before doing it. Do not alter the original deposit request to make the change disappear.

Reconcile the glazier final payment

Start the final account with the accepted price. Add only approved variations. Then credit the deposit and any glazing progress invoice payments once each.

The account should show:

• Accepted quote price
• Approved variations, each with its reference
• Revised account total
• Cleared deposit already received
• Cleared progress payments already received
• Remaining balance
• Incomplete or disputed items recorded separately

Do not treat the deposit as extra income on top of the accepted price. Do not deduct it twice because it appears on both a receipt and the customer account.

If a return visit remains for trims or making good, check the agreed payment stage. Record what is complete, what remains and whether the final trigger has been reached. Do not invent a new trigger after installation.

A glazier final payment should be traceable back through the accepted quote, approvals, variations and prior receipts. Send the customer an account they can follow without reconstructing the job from messages.

Yes Foreman can keep the quote, approvals, glazier deposit invoice, payment record, supplier order, variation and job costs attached to the same job. The point is a clean chain from opening reference to final account, not another document stored in isolation.

Take the next made-to-measure order and fill in the release card before sending the supplier purchase order.
