Tank sizing calculator
Roof, rainfall and usage turned into a recommendation.
Wollopit for water tank installers
Water tank installers: size the tank from the rain. Roof, rainfall and price in one.
Customers unsure what size they need and quotes that need a phone call. We build tank sizing calculators and booking systems that turn visitors into buyers.
Looking for a water tank size calculator for your website?
The first question is always 'what size tank?'. A sizing tool based on roof area, local rainfall and usage answers it properly and hands you a qualified lead.
Wollopit builds job systems, quoting tools, booking systems and websites for water tank installers around how you actually work. We connect the apps you already use, replace the ones holding you back and look after the lot on our own servers, so you can get back on the tools.

05How we work
The process
Some people dip their toe in. We turn up in a rebreather.
We get properly below the surface of your water tank business: the systems, the busy days and the jobs everyone hates. Then we fix the bits that matter most first.
- 01
Think
We spend time with the people doing the work, see where the hours go and work out what's actually slowing you down.
- 02
Archi-tech
We plan it before writing code: your data, customers, payments, the tools you keep, hosting and cost.
- 03
Build
Real engineering, shown to you early and often. Usually the most painful bit first, so you get a win quickly.
- 04
Look after
We host it, maintain it and keep improving it. When something breaks you call the people who built it.
06Questions
FAQ
Things water tank installers ask us.
Something else on your mind? Ring 0423 011 252 and ask the people who'd build it.
Can the calculator use local rainfall data?
Yes. We can use rainfall averages by postcode so recommendations suit the customer's area.
How much does it cost?
It depends on what you need, so we quote up front once we understand your water tank business. No surprise invoices, no lock-in and you own what we build.
We already use a job management app. Do we have to switch?
No. If it's doing its job we build around it: the missing features, the integrations and the website on top. If it's holding you back we'll show you what replacing it would involve before anything changes.
Will it work on a phone in the van?
Yes. Everything we build for trades works on a phone first, with big buttons and photos that upload when you get signal back.
Who looks after it once it's built?
We do. We host it on our own managed servers and keep it updated and secure. When you need something you ring the people who built it.
