Graftum was built by the team behind Ivy Electric, a London electrical contractor — and it runs Ivy's own jobs, timesheets and certificates every single day. When something annoys us on site, it gets fixed the same week.
No card needed. Then £3, £6 or £9 a month per company — not per user — until the end of your first year, and a permanent founders' discount after that. The price of a coffee, for the system that runs your jobs.
Start free →Price the boiler swap or system upgrade on site from your own price list — labour and materials kept apart, with options such as a different boiler or a system flush priced separately. The customer gets the quote as a link on their phone, with your logo and terms, and every revision replaces the old one.
When it goes ahead, the job runs in the same place: the engineer clocks in on it, the certificates are stored against it, and it is invoiced from there.
