Construction Invoice Template: How to Bill Clients and Get Paid Faster

Most construction payment delays start with the invoice, not the owner. A billing application missing required supporting documentation, submitted on the wrong day, sent to the wrong contact, or formatted incorrectly gives the owner a legitimate reason to hold payment until the next billing cycle — a 30-day delay on a $200,000 invoice at 8% annual interest costs the contractor $1,333 in financing cost. Do it every month and the year's billing friction costs more than most contractors spend on marketing.

Construction invoicing isn't like invoicing in other industries. A general contractor on a commercial project doesn't send a PDF with a dollar amount — they submit a payment application with a schedule of values, a continuation sheet, conditional lien waivers for all sub tiers, and sometimes certified payroll. Getting paid fast means having that package complete, correct, and submitted on the day the contract specifies.

Labor records from construction time tracking software feed directly into the billing process — T&M invoices pull from timesheet exports, certified payroll billing requires GPS-verified hour records, and progress billing percent-complete calculations are supported by documented labor hours by cost code. This guide covers every invoice type used in construction, what must be included, common billing mistakes, and copy-ready templates.

 For contractors who need cleaner field records, construction photo documentation software can also help support percent-complete claims, progress billing, and owner communication. 

Construction Invoice Types

Different contract structures require different invoice formats.

1. Progress Billing (AIA G702 / Schedule of Values)

Standard format for commercial GCs on lump sum and GMP contracts. Billing organized by line item (the schedule of values), showing original contract value, work completed to date, retainage held, and amount due this period.

Used with: Lump sum contracts, GMP contracts, design-build

Requires: AIA G702 (application for payment cover sheet) + G703 (schedule of values continuation sheet)

2. Time and Materials (T&M) Invoice

Line-item invoice showing actual labor hours, materials, and equipment used — plus the applicable markup. Labor hours come directly from the construction timesheet app.

Used with: T&M contracts, change order work billed T&M, extra work orders

Requires: Timesheet backup by worker, material receipts, equipment log

3. Unit Price Invoice

Billing based on measured quantities of completed work × unit price from the contract. Common in civil and site work.

Used with: Unit price contracts (road work, utilities, earthwork)

Requires: Field measurement verification, owner-certified quantities

4. Lump Sum Progress Payment

Simplified progress billing — owner and contractor agree on milestone or percent complete, payment releases accordingly. Common on smaller projects without a formal schedule of values.

Used with: Residential, smaller commercial, specialty subcontracts

Requires: Percent complete agreement, photographic documentation

AIA G702/G703 Progress Billing: The Standard Format

The AIA G702/G703 is the most widely used billing format in commercial construction. Understanding every field eliminates billing disputes before they happen.

AIA G702: Application and Certificate for Payment

Header fields:

To Owner:        [Owner name and address] Project:         [Project name and address] Contract For:    [Brief scope description] Contract Date:   [Date of prime contract] Application No.: [Sequential — Application #1, #2, etc.] Period To:       [Billing period end date] Architect's Project No.: [If applicable] 

Financial summary fields:

1. Original Contract Sum:           $[original contract value] 2. Net Change by Change Orders:     $[approved COs to date, net of credits] 3. Contract Sum to Date:            $[Line 1 + Line 2] 4. Total Completed and Stored:      $[from G703 Column G total] 5. Retainage:    a. % of Completed Work:          $[retainage % × completed work]    b. % of Stored Material:         $[retainage % × stored materials]    c. Total Retainage:              $[5a + 5b] 6. Total Earned Less Retainage:     $[Line 4 − Line 5c] 7. Less Previous Certificates:      $[total previously paid, per G702 history] 8. Current Payment Due:             $[Line 6 − Line 7] 9. Balance to Finish Including Retainage: $[Line 3 − Line 6] 

Contractor certification (G702 bottom): Contractor certifies the work has progressed as indicated, quality is in accordance with the contract documents, and the amount certified is due and owing. Notarization may be required depending on contract or jurisdiction.

AIA G703: Schedule of Values Continuation Sheet

The G703 breaks the contract into line items — each representing a scope element with its own budget, completion percentage, and dollar value.

Column structure:

A: Item No. B: Description of Work C: Scheduled Value (budget per line item) D: Work Completed From Previous Application E: Work Completed This Period F: Materials Presently Stored G: Total Completed and Stored (D+E+F) H: % (G÷C) I: Balance to Finish (C−G) J: Retainage 

Line item example:

Item | Description        | Value    | Prev    | This    | Stored | Total    | %   | Balance -----|-------------------|----------|---------|---------|--------|----------|-----|-------- 1.1  | Mobilization      | $12,000  | $12,000 | $0      | $0     | $12,000  | 100%| $0 1.2  | Site Demo         | $28,500  | $18,525 | $9,975  | $0     | $28,500  | 100%| $0 2.1  | Concrete Footing  | $67,000  | $0      | $40,200 | $0     | $40,200  | 60% | $26,800 2.2  | Structural Steel  | $145,000 | $0      | $72,500 | $0     | $72,500  | 50% | $72,500 

Setting up the schedule of values: The schedule of values is negotiated with the owner/architect before the first billing. Front-loading (inflating early items to improve cash flow) is a common tactic but owners and architects push back — they look for front-loading and may reject applications that don't reflect actual percent complete.

Percent complete on each line item should be supportable by field documentation — photographs, daily reports, and construction time tracking hours by cost code. An owner who disputes the 60% complete claim on concrete footings gets GPS-verified labor hours showing the work performed.

 If your team needs better field documentation, photo documentation for general contractors can help connect daily jobsite progress to billing support. 

T&M Invoice Template

T&M billing is the most documentation-intensive invoice type — and the most defensible when backed by proper records.

Labor hours on T&M invoices must match timesheet records. When daily hours come from GPS-verified time card apps for construction — with timestamps and location stamps — an owner who disputes labor hours faces digital records, not handwritten timesheets. This is the difference between a T&M invoice that gets paid and one that generates a call asking for proof.

Required Supporting Documentation by Invoice Type

Lien waivers: Most commercial payment applications require conditional lien waivers from the GC and all sub tiers for the current billing period, plus unconditional waivers (confirming prior period payment was received) from all sub tiers. Missing waivers from a single sub stop the entire billing application.

Construction employee time tracking app exports are increasingly accepted — and sometimes required — as timesheet backup for T&M billing and certified payroll. GPS-verified exports show worker name, date, clock-in/out times, location, and total hours — more complete than any handwritten timesheet.For more resources on contractor timesheets, see GPS timesheets for contractors. 

Retainage on Invoices

Most commercial construction contracts hold retainage — typically 5–10% of each payment application — in reserve until substantial completion or final completion. See Construction Retainage for the full retainage management guide.

On the G702: Retainage appears in lines 5a and 5b, reducing the Current Payment Due (line 8). Track cumulative retainage held in the G702 history — it's a receivable that must be actively managed and released.

On T&M invoices: State the retainage percentage and dollar amount explicitly on the invoice. Calculate: Labor + Material + Equipment subtotal → apply retainage % → show net amount due after retainage.

Retainage reduction: Many contracts allow retainage reduction to 5% (from 10%) after 50% completion, or at substantial completion. Track this proactively — owners don't typically volunteer retainage reductions; the contractor must request them per the contract terms.

Billing Cycle Best Practices

Submit on the contract-specified date. AIA contracts typically specify the 25th of the month or the last day of the period. Missing the submission date often pushes payment to the next cycle — a 30-day delay on every invoice that slips.

Know the approval chain. Who reviews the application? Architect first, then owner? Just the owner? Construction manager? Each additional approval step adds 3–7 days. Submitting to the wrong contact at step 1 starts that clock over.

Submit complete the first time. An incomplete application gets returned — missing lien waiver, missing certified payroll, unsigned T&M ticket. Every return cycle costs 7–14 days. Build a pre-submission checklist and run it before every application goes out.

Front-load where possible within reason. The schedule of values is negotiated — allocate higher values to early items (mobilization, site work, foundations) to improve early-project cash flow. Architects will flag obvious front-loading but reasonable allocations are standard practice.

Track payment receipt against due dates. Contract specifies owner pays within 30 days of application — calendar it. On day 31 without payment, send a formal follow-up. Prompt payment laws impose interest on late payment in most states.

 For teams that need stronger daily records, jobsite photos and daily progress tracking can help support payment applications.

Common Billing Mistakes That Delay Payment

Missing or incorrect supporting documentation The single most common cause of delayed payment. Build a document checklist per invoice type — run it before submission, not after the call asking for what's missing.

Overbilling percent complete Claiming 80% complete on a line item that's 60% complete invites a site visit and a revised application. Legitimate documentation — photographs and construction crew time tracking hours by cost code — supports honest percent complete claims. Overbilling damages trust and creates disputes.

Submitting to the wrong contact The project administrator is often not the same person as the accounts payable contact. Confirm the submission address for payment applications at project kickoff — not after the first missed deadline.

Not tracking what's been paid vs. billed G702 line 7 (Less Previous Certificates) must match the actual payment history. Errors here create reconciliation disputes. Maintain a running payment log: application number, amount applied, amount certified, amount paid, date paid.

Letting sub waivers lag GC conditional waivers are easy to produce. Sub waivers require coordination — a sub who won't provide a waiver until they're paid creates a waiver gap that holds the GC's entire application. Build sub waiver collection into the pay cycle, not the day before the application is due.
No change order tracking on the billing Approved change orders increase the contract sum (G702 line 2). Unapproved change orders should appear as pending items separate from the main application. Mixing approved and pending COs into the base application creates disputes.
