A real Sunday emergency call-out
It's 9pm on a Sunday and Dave's boiler has packed in. You drive out, replace the diverter valve, and bleed the system. Total: £350 (£180 call-out + £100 labour + £70 parts). Sitting in the van afterwards, you message Wedge: "Invoice Dave Smith £350 for emergency boiler call-out, parts and labour." Wedge generates a clean PDF invoice, breaks out the parts and labour line items, sends it to Dave on WhatsApp with a card payment link, and chases him on day three if he hasn't paid. When Dave pays, £346.50 lands in your bank account — Wedge keeps £3.50. No subscription, no monthly fee, nothing to remember to cancel. If Dave never pays, Wedge never charges you.

Frequently asked questions
Can I show my Gas Safe number on every invoice?+
Yes. Add your Gas Safe registration number once during sign-up and it appears on every invoice and quote you send — required for any gas work and reassuring for customers.
How do I split parts and labour on emergency call-outs?+
Just tell Wedge in plain English: "£180 call-out, £100 labour, £70 for the diverter valve." Our AI breaks it into separate line items on the invoice. You can also add VAT, mark items as zero-rated, or note them as parts-only.
What about call-out fees versus hourly rates?+
However you charge, Wedge takes it as you describe it. Mention "£90 call-out plus £55/hour for 2.5 hours" and Wedge generates clear line items with the maths done. Your customer sees exactly what they're paying for.
Can customers pay before I leave the property?+
Yes — the WhatsApp message includes a Stripe payment link. Most card payments confirm in seconds. You'll get a WhatsApp notification when the money lands, often before you've packed the van.
How do I invoice for boiler servicing contracts?+
Annual service plans work the same way — send the customer their yearly invoice via WhatsApp when the service is due. For ongoing maintenance contracts where you bill monthly, just message Wedge each month.
I subcontract for a heating company — can I invoice them with VAT?+
Yes. If you're VAT-registered, toggle that on at sign-up and Wedge calculates 20% VAT automatically. You can also invoice with reverse-charge VAT for CIS-style B2B work — just mention it when sending.
