02 The problem
Three bits of software. A spreadsheet. Paper certificates. And you joining it all together.
Most job apps only handle the obvious bit. You still open something else for the accounts, another tool for certificates and your inbox to work out supplier prices.
Then come the missed reminders, cold quotes and evenings spent copying numbers between places.
The Job Manager replaces that juggle with one tidy trail through the whole business.
03 What it does
The whole business, not just the diary.
Quotes that do the maths
Professional customer options, online acceptance and supplier prices read from emails and marked up automatically.
Quotes and AI pricingInvoices and getting paid
Invoice straight from the job, take bank payments and let the system record them and chase overdue work.
1% capped at £4 with bank payCertificates and records
Complete certificates on site, save safely as you type and send the finished PDF to the customer or landlord.
Built around your tradeThe accounts side
See real job profit, match supplier costs, reconcile the bank and give your accountant a clean year-end pack.
Less separate bookkeepingWork that comes back
Service reminders become one-tap booking leads, while review requests help finished jobs build your reputation.
Reminders and reviews04 Built around you
Your own app. Not another login you have to bend around.
Off-the-shelf software decides how your business should work. This starts with how it already works, then tidies the journey and removes the repeated admin.
Need a report, a form or a different way for jobs to flow? The system can grow with the business instead of forcing you to start again.

05 What it replaces
Fewer subscriptions. Fewer gaps between them.
The first live version replaced Tradify, QuickBooks and a separate gas-certificate tool, then added useful things those tools did not cover.

The first Job Manager is live with J Hacking Heating & Plumbing. It replaced Tradify, joined the accounts and certificate work into the same system and keeps developing around the business.

08 Questions
The things you'd sensibly ask.
Is it just for gas engineers?+
No. The first version was built for a gas and heating engineer, but the core journey works for plumbers, electricians and similar service trades. I adapt the trade-specific parts around you.
Is this another off-the-shelf app?+
No. You get your own version, built around the way your business works, hosted and maintained by GSD Lab.
Do I own my data?+
Yes. Your customers, jobs, documents and business data remain yours.
What if I need something it doesn't do?+
That's the point of building it this way. Useful reports, forms and changes to the job flow can be added when you need them.
Do I have to leave my current software on day one?+
No. We can move things over in sensible stages so the business keeps running while the new system becomes familiar.
