GST invoice for hourly services

Approved service hours billed for one identified work period

An hourly service invoice should identify the work period and approved quantity of hours so the customer can match the charge with the agreement. This format suits maintenance or support work billed against an accepted timesheet. It keeps service units separate from the entered tax calculation. The demonstration tax split is a manually selected example; neither the service description nor the hourly price establishes the applicable GST treatment.

How the filled example works

The fictional studio bills 20 approved hours at INR 1,500 before tax, giving INR 30,000 taxable value. The entered example applies INR 2,700 CGST and INR 2,700 SGST, producing INR 35,400 total. Those amounts show arithmetic with a chosen rate; they do not classify website maintenance. The supplier and customer GSTINs, place of supply and SAC remain verification fields rather than invented identifiers.

Prepare the supporting record

Prepare the service agreement, accepted timesheet and customer billing details before editing. Confirm whether the quoted hourly amount includes tax or is explicitly before tax. Check how fractions of hours and any minimum billing block were agreed. Keep individual support tickets as separate supporting records if needed; the invoice can use a clear service-period description and reference without exposing unnecessary customer or system information.

Resolve this scenario before issuing

Resolve the service classification and place of supply from the actual transaction, then enter the approved tax treatment. A customer’s billing city or a remote-work location alone should not be used as a shortcut to choose the split. If an advance or earlier invoice already covers some of the hours, explain the actual adjustment so the same work is not billed twice. Check any applicable invoice, IRN or QR requirements before issuance.

How to edit and share the document

Use Word to add a concise work-order or timesheet reference, or use Excel as an editable record of the entered quantity, price and tax lines. The worksheet does not recalculate totals or determine tax rates. Multiply the hours and agreed pre-tax price independently, confirm the selected tax amounts and compare the revised total with the customer’s approval. Review the PDF and replace every verification field before issuing an actual invoice.

Invoice identity and tax review

A GST invoice requires more than a correct total. Review supplier and customer identity, the invoice date and financial-year number, the supply description, HSN or SAC, quantity where relevant, taxable value, tax rate and tax amount. State identifiers and shipping addresses help explain the transaction, but they do not independently determine its tax treatment. All GSTINs remain placeholders in these examples. Use the applicable official rules and your actual transaction records when preparing an issued invoice.

Review this scenario

• Confirm the accepted service hours and billing unit.
• Check whether the price is before tax.
• Verify supplier and customer details and GSTINs.
• Determine SAC, place of supply and tax treatment.
• Check prior bills or advances for the same hours.
• Review invoice particulars and any applicable IRN or QR requirements.
