Answers calls & messages

When someone calls or WhatsApps your Gaffer number, it responds instantly — qualifies the job, gives rough pricing, checks your diary, and books them in. Sounds like you, works 24/7.

Invoices & payment links

Tell Gaffer what you did and it creates a professional invoice with a payment link — no accounting software needed. Customer pays by card in one tap.

Location-aware scheduling

Gaffer knows your diary, your location, and drive times between jobs. Running behind? Just say "running late" and it texts your next customer with an updated ETA.

Chases the money

Gaffer tracks every invoice and sends polite reminders at 7, 14, and 21 days. No more awkward "just following up" texts. It even tells you who owes what each morning.

Business reports

Ask "how did I do this month?" and get a full summary — jobs completed, revenue, outstanding payments, new reviews, busiest days. A weekly report lands every Monday.

Gets you reviews

After every completed job, Gaffer sends a personalised review request. Or say "message my last 10 customers asking for a review" and it handles the lot.

Morning briefing

Every morning, Gaffer messages you with today's jobs, drive times, outstanding payments, and overnight enquiries. Start your day knowing exactly what's ahead.

Team support

Got a mate or apprentice? Add their number and they can message Gaffer too — check the diary, log completed jobs, create invoices. You control what they can access.

Quote follow-ups

Sent a quote but heard nothing back? Gaffer follows up automatically after a few days with a friendly nudge. No more leads slipping through the cracks.
