Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰London building work splits sharply between high-ticket domestic refurbishment (loft extensions, side-returns, basement digs across the inner boroughs run £40k–£200k routinely) and CIS-deducted subcontract work for main contractors on commercial sites. The staged-payment quote is the typical opening move on any sizeable domestic project — 20% deposit, then milestone payments tied to first fix, second fix, and completion, with a 5–10% retention. Wedge generates the schedule once and sends each stage invoice when you message that the milestone is done. Reverse-charge VAT applies to most B2B subcontract work on the commercial pipeline; the £50 cap on Wedge's 1% fee is meaningful on the larger domestic invoices where a single stage payment can exceed £20,000.

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.

Tell Wedge the schedule once (e.g. "20% deposit, 25% first fix, 25% second fix, 20% completion, 10% retention") and the schedule is set against the quote. You message Wedge when each stage is done and the next invoice goes out — no re-typing. Each invoice fee is capped at £50.
Yes — flag the customer as VAT-registered and under CIS when you send and the invoice formats with the correct reverse-charge wording. You don't charge VAT to the main contractor; the invoice notes it instead. Standard B2B construction reverse-charge rules apply.
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.
