Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰Birmingham building work is shaped by HS2 Phase 1 more than any other UK city — main-contractor subcontract chains on the supply pipeline have run for years and continue to feed CIS-deducted invoicing across the West Midlands. The Smithfield, Paradise, and Curzon Street commercial pipelines layer additional subcontract demand on top. For independent builders working domestic, Solihull and Sutton Coldfield generate higher-ticket refurb work than the city average (full extensions, loft conversions, garage conversions routinely run £30k–£80k). The mix of high CIS density and a high-ticket domestic market means staged payments, retention handling, and reverse-charge VAT formatting are routine — not edge cases.

You've won a loft extension job — £18,500 inclusive of materials, labour, and Building Control. The customer wants to pay in stages: 20% deposit on signature, 25% at first fix, 25% at second fix, 20% on completion, 10% retention released after 30 days. Message Wedge: "Quote Tom Williams £18,500 for loft extension at 22 Beech Close, broken into 20% deposit, 25% first fix, 25% second fix, 20% completion, 10% retention." Wedge generates the quote with the schedule clearly laid out. Tom signs digitally and pays the £3,700 deposit immediately — £3,663 lands in your account. As you hit each stage, you message Wedge to send the next invoice. The retention sits in customer's account; you message Wedge to invoice for it after 30 days. Total Wedge fees on the £18,500 job: £185. No subscription you have to pay even on a slow month.

Include the retention as the final stage in your payment schedule when you set the quote (e.g. "10% retention released after 30 days"). The retention is shown clearly on the original quote; you message Wedge when the period ends and the retention invoice goes out automatically.
Yes. Send Wedge the schedule once ("20% deposit, 30% first fix, 50% completion"), and we'll generate each stage invoice when you tell us the stage is done. The customer sees the schedule on the original quote so there are no surprises.
If you subcontract under CIS, mention it when invoicing ("CIS deduction at 20%") and Wedge will show the gross amount, the 20% CIS deduction, and the net amount payable. The contractor pays you the net; HMRC paperwork stays your responsibility.
Yes. When you set up staged payments, include the retention as the last stage (e.g. "10% retention released after 30 days"). Customer pays everything else upfront; you message Wedge to send the retention invoice when the period ends.
Yes — useful when customers want to see exactly what they're paying for. Tell Wedge "£4,500 materials, £6,000 labour" and the invoice breaks them out as line items. You can also add reverse-charge VAT if applicable.
If you're VAT-registered, yes — standard 20% VAT on most domestic work. Wedge calculates and shows VAT automatically. For specific reduced-rate work (renovations of empty homes, conversions), you can override to 5% per line item.
When a customer asks for an addition ("actually, can you add a roof window?"), message Wedge to send a separate change-order invoice. Customer agrees and pays in WhatsApp — no awkward conversations about scope creep.
