Invoicing software for electricians and plumbers in Nigeria

A rewire in Lekki or a pipe replacement in Surulere gets done on Tuesday and the invoice gets written on Saturday — if at all. Verbal quotes turn into arguments over what was agreed, and by the time you chase the client, the goodwill from a job well done has already faded. Slow invoicing is the single biggest reason working capital gets stuck for trade businesses here.

Cable, breakers, sockets, PPR pipe, elbows, tank fittings — they move from the workshop shelf to a technician's van to a customer's ceiling with no record in between. At month end you cannot say whether a coil of 2.5mm was used on a job, sold over the counter, or simply walked. Without stock visibility you are quoting from guesswork and eating the difference.

Copper, fittings and imported components move with the naira, so a price you quoted three weeks ago may already be below your landed cost. Most tradesmen mark up from memory instead of from the current purchase price, and only discover on a big job that the margin was gone before the first technician arrived on site.

Once taxable turnover crosses the registration threshold, VAT has to be charged, invoices have to carry the right details and a monthly VAT return has to go to the Nigeria Revenue Service (NRS, formerly FIRS). With receipts in a shoebox and invoices in a WhatsApp thread, preparing that return costs days you would rather spend on site. Confirm current registration rules and thresholds with NRS or a local tax professional.

Build a quote on your phone at the client's gate — materials pulled from your price list, labour lines, and a clear total. When the client approves it, convert it to an invoice in one tap and send it by email or WhatsApp before you leave. Payments and part-payments are recorded against the job, so you always know who still owes you and how much.

Every cable, fitting and fixture is tracked in real time. Issue parts to a job and stock comes off automatically; keep a separate location for each van so you can see what each technician is carrying. Reorder alerts warn you before you run out of the fast movers, and stock counts finally reconcile with what you actually sold.

Materials are valued at what you actually paid, so when purchase costs move, your job costing moves with them. Each completed job shows materials, labour and margin side by side, and AI insights flag the job types and customers that quietly lose you money. You price the next quote from data, not from memory.

Snap a supplier receipt and AI extracts the amount, the vendor and the VAT for you. Invoices carry your TIN and the correct VAT treatment, purchases and sales are categorised as they happen, and your VAT position is ready when the monthly VAT return is due to NRS. Nigeria's National E-Invoicing Solution is rolling out in phases — confirm what applies to your business with NRS or a local tax professional.
