Its article was last updated April 30, 2024; the workbook has not been independently tested here. Treat it as a working billing layout, not as a guarantee that the document meets GST invoice rules.
Download the free Excel template
Download the labour contractor bill format from ExcelDemy. The page provides a reusable workbook and an example of how to enter work details and calculate charges. Because the download has not been independently tested, check the formulas and formatting in your copy before using it for a customer bill.
The example’s cell references—such as =E22*F22 for duration, =G22*H22 for wages, =I31*I32 for tax, and =I31+I33-I34 for the final amount—only apply to that example’s worksheet layout. If you move or add columns, use formulas based on your own cell locations.
What to include in a labour contractor bill
A practical bill should make it easy for both parties to identify the work, verify the amount, and track payment. ExcelDemy’s suggested fields include:

Set up the bill and calculate labour charges
Choose the labour basis
Use a line-item structure that matches the agreement: hours, days, time-based work, a project amount, or a mix of wage types. For each item, record enough detail to support the quantity and rate—for example, the work date, person, days or hours, rate, and resulting amount.

Calculate each line and the amount due
- Enter the quantity or duration for each work item.
- Multiply that quantity by its agreed rate to calculate the line amount. For example, seven days at a daily rate is 7 × the daily rate.
- Sum the line amounts to get the subtotal.
- Apply any agreed discount or other adjustment, then calculate tax only when applicable and using the treatment that applies to the transaction.
- Calculate the final amount from the subtotal, adjustments, and applicable tax; show the arithmetic clearly so the client can check it.
ExcelDemy’s example includes a tax entry, but it is illustrative—not a recommended or universally applicable rate. A tax-rate cell in a spreadsheet does not determine which tax treatment applies.
Is a generic Excel bill a GST tax invoice?
No. A generic commercial bill is not automatically a compliant GST tax invoice. CBIC’s GST invoice rules set out particulars for tax invoices, including supplier name, address and GSTIN; a consecutive serial number unique for the financial year; issue date; recipient details; accounting code for services; service description; taxable value; tax rate and tax amount; and additional particulars depending on the case. CBIC separately specifies details for a bill of supply.
Rank #3
- Padded convenience: carry invoices to the job site in a pad that keeps your papers neat
- Make room for details: a large work description area gives you space for Descriptions of the work performed including products, service and labor
- 50 three-part carbonless receipts: Provides a perforated customer receipt with perked pink and yellow duplicates
- Standardized for professionals: fields capture work-order number, bid number and the site address
- Get paid on time: payment instructions at bottom tell the customer when and what to pay
Before issuing a document, identify whether the applicable document is a tax invoice, bill of supply, or another document, and confirm which particulars apply to your circumstances. Do not assume that the template’s tax fields make it compliant.
Timing and copies for taxable services
CBIC’s invoice-rules page states: “The invoice referred to in rule 1, in case of taxable supply of services, shall be issued within a period of thirty days from the date of supply of service”. The page also states exceptions, so check the applicable rule rather than treating 30 days as an exception-free deadline. It says service invoices are prepared in duplicate, with the original marked for the recipient and duplicate for the supplier; how that is handled in an electronic workflow may differ in practice.

Do not confuse a bill template with an e-invoice utility
IRIS IRP documents a separate Excel-based utility for generating e-invoices through its portal. Its help pages describe signing up, adding or accessing a GSTIN, logging in, and downloading the utility; the desktop utility supports Excel 2007 and above. That utility is distinct from an ordinary labour bill workbook: downloading a generic template does not generate an IRN or establish that a contractor is required to use the utility.
For the utility’s process and requirements, see IRIS IRP’s Excel Utility help page.
