01 — THE CHALLENGE

Four tools, none of them talking

Quotes lived in one app, invoices in another, time tracking in a third, customer records in a spreadsheet — and the real coordination happened in a WhatsApp group at 7am. Every job was re-typed at least three times, and every re-type was a chance to get it wrong.

The per-seat pricing stung hardest: £570 a month across six staff, for tools the team actively disliked.

02 — WHAT WE BUILT

One platform, their name on it

Hartley OS: quoting, job board, invoicing and customer records in one system, with the AI layer underneath — enquiries answered, invoices chased and the Monday report compiled without a human touching any of it.

Same-day quotes from a phone, on site
Job board that replaced the WhatsApp chaos
Invoices raised and chased automatically
No per-seat fees — the seventh hire costs £0
03 — THE RESULT
"The subscriptions are gone, the 7am WhatsApp scramble is gone, and quotes go out the same day. It's the first bit of software that feels like it works for us."
