Create Clear Invoices for Glazing Work
A glazing invoice gives commercial glass and architectural aluminum contractors a consistent way to bill storefront, curtain wall, windows, entrances, glass, framing, sealants, hardware, labor, lifts, testing, approved changes, retainage, and other completed work. Clear billing helps customers understand what has been furnished or installed, how progress was measured, and how the current amount due was calculated.
This Glazing Invoice Template is designed for commercial glazing contractors, glass subcontractors, curtain wall and storefront installers, architectural aluminum contractors, project managers, office administrators, billing staff, and construction business owners.
What Is a Glazing Invoice?
A glazing invoice is a customer-facing billing document used to request payment for completed architectural glass and aluminum work. Depending on the contract, billing may be based on a schedule of values, percent complete, installed square footage, openings, doors, unit prices, approved stored materials, time-and-material work, change orders, or a combination of these methods.
Typical billable work may include storefront, curtain wall, window wall, punched windows, aluminum entrances, glass doors, interior glazing, mirrors, aluminum framing, glass units, gaskets, sealants, flashing, hardware, lifts, glass-handling equipment, freight, testing support, protection, punch-list work, and closeout.

How to Use the Template
- Enter the glazing contractor, customer, project, billing contact, subcontract, purchase-order, and remittance information.
- Assign a unique invoice number and confirm the billing period, invoice date, due date, and payment terms.
- List schedule-of-values items, glazing systems, openings, entrances, stored materials, equipment items, or approved changes separately.
- Record the agreed billing quantity or percent complete for each line item.
- For square-foot billing, identify the applicable system, elevation, floor, glass type, or installed area when required for backup.
- For stored materials, document the material type, quantity, value, storage location, invoice or purchase-order reference, and required supporting documentation.
- Record lifts, glass-handling equipment, crane time, labor, sealant work, or other separately compensable items only when the agreement permits them to be billed independently.
- List approved change orders separately from original subcontract work.
- Apply previous billing, stored-material credits, retainage, taxes, payments, credits, and backcharges according to project requirements.
- Review installed quantities, schedule values, stored-material amounts, rates, backup documentation, and calculations before issuing the invoice.
A glazing subcontractor submits a monthly progress invoice for a three-story commercial building. The billing includes 72% completion of the curtain wall schedule item, 100% of first-floor storefront framing, 10 completed aluminum entrances, 6,300 square feet of installed insulating glass, approved stored spandrel glass awaiting installation, and an approved change for revised perimeter sealant at two elevations. The invoice deducts prior billing, applies contract retainage, and references the current schedule of values, material invoices, installation records, and approved change authorization.
Best Practices for Glazing Invoices
- Match invoice descriptions to the subcontract, schedule of values, proposal, and approved changes.
- Separate storefront, curtain wall, windows, entrances, glass, sealants, and other systems when they have different schedule values.
- Use the project's agreed measurement basis for square footage, openings, doors, stored materials, equipment, or percent complete.
- Identify elevation, floor, opening, or area when that information helps the customer verify installed work.
- Reconcile installed glass area and framing progress with current field records before billing.
- Document stored materials separately from installed work and follow the project's documentation requirements.
- Keep approved changes separate from base-subcontract billing.
- Reference signed time-and-material tickets when billing extra labor or equipment.
- Apply retainage, taxes, prior payments, credits, and backcharges consistently.
- Preserve revised, disputed, credited, and voided invoice history.
Common Glazing Invoice Mistakes
- Using vague descriptions such as “glazing progress” without a measurable billing basis
- Billing glass or framing quantities that do not reconcile with current field records
- Combining storefront, curtain wall, entrances, and interior glazing when they use different schedule values
- Billing stored materials without the documentation required by the contract
- Billing unapproved revised glass types, access changes, or additional sealant as base scope
- Billing equipment without an approved rate or supporting record
- Using material or unit prices that do not match the approved agreement
- Applying the wrong retainage percentage or tax treatment
- Failing to deduct previous billing, credits, payments, or backcharges
- Issuing a final invoice before punch work, replacement glass, approved changes, closeout documents, and retainage are reconciled
Frequently Asked Questions
What should be included on a glazing invoice?
Include contractor and customer information, project details, invoice dates, payment terms, glazing-system descriptions, quantities or percent complete, schedule values or rates, approved changes, stored materials where applicable, taxes, retainage, previous billing, payments, and amount due.
How should commercial glazing work be billed?
Use the billing method established by the subcontract. Common methods include schedule-of-values progress, installed square footage, openings, doors, unit prices, approved stored materials, time-and-material work, or change orders.
Should glass square footage appear on the invoice?
It can be useful when square footage is the billing basis or provides supporting detail for progress. Identify whether the quantity represents current-period installation, cumulative installation, stored material, or another agreed measurement.
How should stored glass and aluminum be billed?
When the contract allows stored-material billing, list the material, quantity, value, storage location, supporting vendor documentation, previous stored amount, installed transfer, and current stored balance as required by the customer.
How should storefront and curtain wall be invoiced?
Use the schedule values or unit prices established for each system. When practical, identify the applicable elevation, floor, zone, frame installation progress, glass installation progress, and other milestones used to support the billed amount.
How should equipment charges be billed?
When equipment is separately billable, identify the boom lift, glass manipulator, crane, scaffold, or other equipment, along with the approved duration, rate, delivery, pickup, or mobilization charges required by the agreement.
How should glazing change orders appear?
List approved changes separately and reference the applicable change-order number, description, approved value, current billing, previous billing, and remaining amount. Examples may include revised glass, additional framing, added entrances, access changes, or remobilization.
When should a final glazing invoice be issued?
Issue the final invoice after billable installation, approved changes, replacement glass, punch-list work, final quantity reconciliation, required closeout documentation, credits, and retainage conditions have been addressed according to the subcontract.
