Why plumbers pick Ovaro
The jobs are done. The paperwork doesn't have to be.
Doorstep estimates
Speak the scope — 'replace combi boiler, drain down, magnetic filter, 2 thermostats' — and Ovaro turns it into a quote the customer signs from their phone.
Emergency callouts
Send a £85 callout invoice on the doorstep with a card link. No 'I'll post it on Monday.'
Mileage between jobs
55p/mile HMRC rate tracked automatically — easily £2,000+ a year in legitimate claims most plumbers miss.

FAQ
Questions from plumbers.
Can I show my Gas Safe number on invoices?
Yes — add it to your business profile and it appears on every invoice, estimate and receipt automatically.
Does it work for both domestic and commercial?
Yes. You can run domestic homeowners and commercial contracts from the same account, with separate customer records and payment terms.
How do I take a deposit on a boiler install?
Send a deposit invoice (e.g. 50%) before ordering the boiler. Ovaro tracks the balance owed and reminds the customer when the install is done.
Can I track which jobs are most profitable?
Yes — by tagging materials and labour separately, Ovaro shows your margin on every job at a glance.
