Architecture Invoice Format
A GST-ready invoice format for an architect / architecture firm in India — with the correct SAC code, the right GST rate, and the line items you actually bill. Fill it in and download a PDF, free and no sign-up.
Architectural services in India are professional services taxed at the standard 18% GST — there is no concessional rate or exemption, so your invoice must carry the correct SAC code and full CGST/SGST (or IGST) breakup. Building-design work sits under SAC group 99832: use 998321 for pure advisory/consultancy, 998322 for residential building projects, and 998323 for non-residential/commercial projects. Because clients often claim input tax credit, a clean invoice with your GSTIN, SAC, stage-wise fees and RERA/COA registration details protects both sides.

What a GST-compliant architecture invoice must include
A GST tax invoice should carry: your name, address and GSTIN; a unique invoice number and date; the client's name, address and GSTIN (if registered); a description of the service with its SAC code (998322 for architecture); the taxable value; the GST rate and amount split as CGST + SGST (same state) or IGST (inter-state); the total in words; and your signature. Architects typically bill in stages tied to project milestones — commonly 10% on concept, 25% on schematic/design development, 40% on working drawings/GFC, and the balance across construction and completion. A retainer or mobilisation advance of 10-15% at signing is standard, and fees are often structured as a percentage of construction cost (roughly 5-10% for residential) or a per-sq.ft rate. Net 15-30 day payment terms per stage invoice are usual.

Architecture invoice — frequently asked questions
What GST rate and SAC code apply to an architect's invoice?
Architectural services attract 18% GST — there is no lower rate or exemption. Use SAC 998321 for advisory/consultancy, 998322 for residential building design, and 998323 for non-residential/commercial projects (all at 18%). Split it as 9% CGST + 9% SGST for in-state clients, or 18% IGST for out-of-state.
Do I need GST registration to invoice as an architect?
Registration is mandatory once your aggregate turnover crosses Rs 20 lakh (Rs 10 lakh in special-category states). Below that you can invoice without charging GST, but you also cannot collect it or claim input tax credit. Many architects register voluntarily because corporate and builder clients prefer a GST invoice they can claim ITC on.
Should GST be charged on reimbursements like sanction fees or printing?
Genuine pure-agent reimbursements — municipal sanction fees, RERA charges, statutory payments made on the client's behalf at actual cost with supporting receipts — can be excluded from the taxable value and billed separately without GST. But your professional fee, printing, travel and any marked-up expenses are part of the service value and attract 18% GST.
How should percentage-of-cost fees be shown on the invoice?
State the basis clearly — e.g. '8% of estimated construction cost of Rs 60,00,000 = Rs 4,80,000' — then apply 18% GST on that professional fee. For stage-wise billing, invoice only the milestone percentage due, reference the stage, and show cumulative fees billed to date so the client can reconcile against the total contract.
