Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰Glasgow building work is heavier on commercial subcontract than Edinburgh — the Clyde Waterfront regeneration, the Govan and Pacific Quay pipelines, and the Lanarkshire social-housing replacement programmes drive sustained CIS-deducted main-contractor work for groundworkers, brickies, and carpenters. Residential refurbishment centres on tenement work — full close repairs, common-stair upgrades, and multi-flat back-court improvements that often invoice through the building factor rather than individual leaseholders. The mix of CIS volume and factor-based residential invoicing makes flexible handling of both flows in the same week essential.

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.

Most Glasgow factors want one invoice billed to the factor as agent, with the property address listed as the work location and apportionment notes for each leaseholder's share. Wedge handles factored invoicing with a flag on the customer record; common-charge breakdown sits in the description field. CIS still applies if the factor is a VAT-registered construction firm.
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.
