Quoting & invoicing built for solar installers in South Africa
Price the panels, inverter, batteries and install in one clean quote, take a deposit for the kit, and invoice on commissioning.
The fastest quote wins the job
The solar installer who sends a proper quote first looks the most professional — and gets the work.
The old way
A R120k system quoted on a WhatsApp voice note, a deposit you’re nervous to ask for clearly, and no paper trail when the client queries the price.
With BlitzBooks
A professional, itemised quote for the whole system, a deposit set in writing, and a tax invoice on commissioning that looks like the serious money it is.

The bits solar installers ask about
Can I take a deposit on a big system?
Yes. Set a deposit percentage so the customer funds the equipment order before you buy it.
Can I send a pro forma first?
Yes. Issue a pro forma invoice for the customer’s financing or approval, then convert it to a tax invoice once paid.
Do I need a card to start?
Yes. A card starts the 7-day free trial. We check it with R1 and refund it straight away, so nothing is charged today. If you keep going it is R200 a month from the day the trial ends. Cancel in Settings before then and you pay nothing.
Will it work on my phone?
Yes — any modern iPhone or Android, plus desktop. Add it to your home screen and it runs full screen like a normal app.
