Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰Birmingham's plumbing market is one of the most CIS-dense in the UK thanks to HS2 Phase 1 — heating and mechanical subcontractors across the West Midlands have been running long-tail multi-year invoice ledgers under main contractors since 2020. The Smithfield, Curzon Street, and Paradise commercial pipelines mean reverse-charge VAT B2B invoicing is a regular requirement, not a once-a-year edge case. Domestic work in Solihull and Sutton Coldfield often runs higher-ticket than the city centre — full bathroom refits, downstairs WC additions, and central heating system replacements are common. The combination of high CIS density and a high-ticket domestic market is unusual; Wedge handles both within the same WhatsApp flow without separate setup.

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.

If you're VAT-registered and subcontract for another VAT-registered construction firm (very common on the HS2 supply chain), reverse-charge VAT applies — you don't charge VAT to the contractor, you note it on the invoice instead. Wedge generates the correct wording automatically; just mention the customer is VAT-registered and subcontracted under CIS.
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.
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.
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.
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.
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.
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.
