Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰Newcastle plumbing is more residential-weighted than the other northern cities in this set — the bulk of independent plumber invoicing is annual landlord-driven system services on the substantial private rented sector across Heaton, Jesmond, and Sandyford, with mid-ticket bathroom refits in the Victorian and Edwardian terraced stock as the secondary stream. Commercial CIS subcontract demand from the Quayside and Stephenson Quarter pipelines exists but isn't the dominant flow. Self-employed plumbers commonly work jobs across the wider Tyne and Wear metro — Gateshead, Sunderland, North Shields — from one base, so a portable WhatsApp-based invoicing flow matters more than a desktop tool tied to a postcode.

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.

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.
