Sound familiar?
These are the problems heating engineers tell us about every day
Emergency work, slow payment
No heating in winter is an emergency. You drop everything to help. But payment takes weeks.
Boiler parts are expensive
Heat exchangers, pumps, PCBs - parts cost hundreds and you're paying upfront.
Lots of small service jobs
Annual boiler services stack up. Invoicing each one manually is tedious.
Certification and paperwork
Gas Safe requirements mean paperwork. Adding invoicing on top is another burden.
Win more jobs with instant quotes
Boiler quotes need exact specs and warranty details. Writing them up properly takes time you don't have.
With Manano, just text or voice note the job details. We'll create a professional quote PDF you can send to Tom before you've even left the site.
