If you fix wiring, pipes or vehicles for a living, a neat written bill does more than ask for money. It shows the customer exactly what they paid for, backs up your warranty, and settles arguments before they start. This guide covers what a tradesperson's bill should contain, with free generators for an electrician bill, a plumber bill and a mechanic or garage bill.
What every service bill should include
- Your business name, address and phone number (and GSTIN if you are GST-registered)
- Customer name and site address — the place where the work was done
- Bill number and date
- Materials used, itemised with quantity and rate
- Labour or service charges, shown separately
- Total in figures and in words
- Warranty or guarantee terms, if any
- Payment details — UPI ID or bank account — and your signature
Show materials and labour separately
Customers trust a bill more when they can see what went into it. Here is a fictional example for an electrician:
| Item | Qty | Rate | Amount |
|---|---|---|---|
| Copper wire, 1.5 sq mm (metres) | 40 | ₹30 | ₹1,200 |
| Modular switch | 6 | ₹120 | ₹720 |
| Labour — rewiring of one room | 1 | ₹1,500 | ₹1,500 |
| Total | ₹3,420 |
Extra details for each trade
- Electrician: type of work, site address, materials with brand or rating, and warranty on the work.
- Plumber: fittings used, labour per job or per visit, site address and any warranty.
- Mechanic or garage: vehicle registration number, spare parts, labour, odometer reading and next service due.
Do you need to charge GST?
Only GST-registered businesses can charge GST. If you are registered, issue a proper tax invoice; see how to create a GST invoice and how to calculate GST on an invoice. If you are not registered, do not add GST to your bill. The tradesperson generators have optional GST, so you can switch it on or off.
