Quote & invoice app for plumbers in South Africa
Built for South African plumbers— branded with your logo, VAT-ready, straight into your customer's WhatsApp.
Get started freeZakr is a quote and invoice app built for South African plumbers. Whether you're replacing a burst geyser in Randburg or roughing in a new bathroom, you can send a branded, VAT-ready quote straight to your customer's WhatsApp before you've packed up your tools — then turn it into an invoice and get paid, all from your phone.
Geyser replacement
Win the geyser call before the next plumber
Burst geysers don't wait. When a customer is phoning around, the plumber whose quote lands first — clear, itemised and professional — usually gets the job. With Zakr you save your rates once, tap in the geyser, callout and labour, and the quote is in their WhatsApp in under a minute. No driving home to type it up on a laptop while three competitors quote ahead of you.
Take a deposit before you buy the geyser
You shouldn't be thousands of rand out of pocket on stock before the customer has committed. Zakr lets you request a deposit the customer can pay online by card or instant EFT the moment they approve — so the money's in before you load the bakkie.
Invoices and payment reminders handled
When the job's done, convert the quote to an invoice in one tap — same line items, new number. Add your banking details for EFT, or let customers pay online. If an invoice goes unpaid, Zakr chases it automatically, so you're not the one sending awkward 'just following up' messages.

Plumbers — frequently asked questions
›Is there a free invoice app for plumbers in South Africa?
Yes. Zakr has a free plan that lets you send 10 quotes or invoices every month with no card and no contract. When you need more, Pro is R75/month for unlimited documents. Most plumbers start free and upgrade once the jobs are rolling in.
›Can I add VAT to my plumbing quotes?
Yes. If you're registered for VAT with SARS, Zakr shows VAT (15%) as a separate line and puts your VAT number on every quote and invoice. Not registered? Leave it off — your documents stay clean and compliant either way.
›How do I quote for a geyser replacement on site?
Save your standard items — geyser unit, callout, labour, drip tray — once. On the next job you tap them in, adjust the price, and send. The customer gets a professional PDF on WhatsApp and can approve and pay a deposit from their phone.
›Can customers pay the deposit online?
Yes. Turn on online payments and customers can pay a deposit or the full invoice by card or instant EFT — the money goes to your bank account. Prefer EFT only? Add your banking details and skip online payments entirely.
