Invoicing Software for Electricians and Plumbers in South Africa

You finish a geyser replacement on Tuesday, the job card lands on the office desk on Friday, and the invoice only goes out the following week. Every day of delay pushes payment further out, and by the time you chase it the customer has forgotten what was agreed. For a small trade business running on cash flow, that lag is the difference between paying suppliers on time and juggling them.

Cable, isolators, elbows, couplings, taps and geyser valves get pulled from the store, loaded onto a vehicle, and half of it never gets recorded against a job. Then you buy the same 20mm fittings again because nobody could find the ones already on the truck. Stock disappears quietly, and material margins on jobs end up being a guess rather than a number.

You quote a rewire or a full bathroom re-pipe based on experience, but once the job runs long or the supplier price on copper moves, the quote and the real cost drift apart. Without a system that puts labour hours and materials against the original quote, you only find out you underpriced when the job is done and the money is short.

Slips from the wholesaler, fuel receipts, subcontractor invoices and cash purchases pile up in the cubbyhole and a shoebox. Every two months you or your bookkeeper have to reconstruct it all to file a VAT201 on SARS eFiling, and there's always a doubt about whether an input VAT claim was missed because a slip went walkabout.

Build a quote on your phone while you're standing in the customer's roof space, convert it to an invoice the moment the work is signed off, and email it before you leave. The invoice carries your company details, VAT number and line-by-line labour and materials, so there's nothing to argue about. Getting paid starts the day the job ends, not the following week.

Track cable, fittings, valves, geysers and consumables as real stock, and treat each vehicle as its own location so you always know what's loaded. When materials are added to a job, they come off stock automatically and land on the invoice — no more billing for parts you forgot or buying duplicates. Low-stock alerts tell you what to pick up at the wholesaler before the next job, not after.

Because materials and labour are captured against the job, you can see what you quoted versus what it actually cost you. Tallium AI's AI insights flag the job types and customers where your margin is quietly slipping, so you can adjust your pricing on the next rewire or re-pipe instead of repeating the mistake all year.

Snap a photo of a wholesaler slip and the AI reads the supplier, date, amount and VAT, then files it against the right expense category. Sales and purchases feed straight into VAT-ready reports so the figures you need for your VAT201 on SARS eFiling are already assembled when the period closes. Please confirm current rules and your own filing position with SARS or a qualified local tax professional.
