Construction Billing Invoice Template

What is a Construction Billing Invoice?

A construction billing invoice is a periodic claim for payment against a running contract, showing the value of work completed to date, less what has already been billed, less retention. It is issued monthly or per claim period rather than once at the end.

That makes it different from a plain construction invoice, which bills itemized costs for a defined piece of work and is usually a one-off. A billing invoice is cumulative. Each one builds on the last, which is why it has to carry a schedule of values, the percentage complete at the end of the previous period, and the total previously certified.

What's Included in This Construction Billing Invoice Template

The invoice itself is one page. The substantiation behind it runs across six more sheets, and every figure on the invoice is calculated from them.

The retention cap is enforced by a formula, so retention stops accruing once the contract limit is reached rather than continuing by accident.

Only approved variations/change orders reach the invoice, which stops a pending claim being billed before it is agreed. And materials on site drop out on the date you record them as incorporated, which is the standard way double counting creeps into progress billing.

Construction Billing Invoice Format: Tax, GST and VAT

The tax label on the Cover changes the document itself. Set it and the header switches between TAX INVOICE, GST INVOICE, VAT INVOICE or a plain INVOICE, with the currency code carrying through every money column.

That matters because the required format is jurisdictional. Australia and New Zealand require a tax invoice with an ABN or GST number to claim input credits.

The United Kingdom and the European Union require a VAT invoice with the registration number and the rate applied. India requires a GST invoice with the supplier's GSTIN and place of supply. The Gulf states require a TRN.

Set the tax label, the tax rate and the currency once on the Cover, and every sheet relabels itself. The contractor bill format your client expects is a labelling and registration-number question, not a different document.

Construction Progress Billing Example

Here is an example of a construction billing invoice: claim 14 on a health precinct project, billing one month against a 15 million contract.

How to Use This Construction Billing Invoice Template

Set the contract terms on Lists first, then update the schedule of works each period. The invoice sheet builds itself, so most of the work is in the substantiation behind it.

Delete every row marked EXAMPLE before the workbook goes near a client.

1. Complete the Cover with the project, client, contractor, invoice date, currency code and tax label.
2. Set the contract rules on Lists: original contract sum, retention percentages on works and on variations/change orders, the retention cap, materials allowance, tax rate, payment terms in days and claim period.
3. Enter the contract value of each section or trade on the Schedule of Works Completed.
4. Record the percentage complete at the end of the previous period and the percentage claimed this period, then let value, balance and retention calculate.
5. Add variations/change orders, setting only genuinely approved ones to Approved, since that status is what releases them into the invoice.
6. List materials on site and off site, entering the incorporation date as soon as goods are installed.
7. Record retention, previous payments and any backcharges or credits on Retention & Payment History.
8. Fill in the From and Bill To blocks, the invoice number and the purchase order on the Invoice sheet.
9. Clear every assertion on the Reconciliation Check before you issue.

The reconciliation panel is the difference between a payment that gets certified and one that comes back. It confirms the invoice ties to its schedules, retention is within the cap, nothing is over 100% complete, and materials are not counted twice. Issuing with one of those failing is how a payment gets rejected on arithmetic rather than on merit.

Invoice vs Progress Claim vs Payment Certificate

These three get used interchangeably and are not the same document. Getting the wrong one can cost you a statutory entitlement.

In Australia a progress claim served under security of payment legislation has to meet statutory requirements the invoice does not, and serving late can extinguish the entitlement. The payment certificate is what comes back, and the certified amount is often not the claimed amount.

Many contracts require all three: a claim under the contract, a certificate in response, and a tax invoice for the certified sum.
