Invoice INV-014 for £350 sent to Dave Smith. ✉️Wedge
Dave Smith paid £350 for INV-014. 💰London joinery splits between high-ticket heritage and conservation work in the central boroughs (Kensington, Chelsea, Notting Hill, Hampstead) where sash window restoration, period skirting reproduction, and bespoke fitted furniture regularly drive £6,000–£25,000 jobs, and CIS subcontract first-fix and second-fix work on the new-build pipelines across Zone 2-3 commercial fit-outs. Kitchen fitting (labour-only with customer-supplied units) is a steady high-volume specialism. Multi-week jobs need staged-payment schedules; the £50 fee cap on Wedge's 1% matters on the larger heritage projects.

A homeowner has bought a 12-unit Howdens kitchen and wants you to fit it. Three days of labour, no materials supplied by you. You quoted £1,500 fixed price for the fit, plus £180 for additional joinery to make the worktop work around a chimney breast. Message Wedge: "Invoice Hannah Reid £1,680 for kitchen fit and chimney-breast worktop alteration at 22 Park Crescent. £1,500 fit, £180 additional joinery — customer supplied kitchen." Wedge generates a clean PDF with both line items, prints your NVQ Level 3 in the footer, sends Hannah the invoice on WhatsApp with a Stripe link, and chases on day three if unpaid. £1,663.20 lands in your account; Wedge keeps £16.80. No subscription. If she never pays, we never charge.

Set a staged-payment quote — typically 30% deposit, 30% midway, 30% on completion, 10% retention released after 30 days. Wedge holds the schedule on the original quote; you message when each stage is done and the next invoice goes out automatically. Useful on the £15,000+ sash window restorations where a single stage payment can exceed £5,000.
Just describe what you did in the message: "First-fix joinery — partition framing, door linings, window boards" or "Second-fix joinery — skirting, architrave, internal doors hung." Wedge picks up the description verbatim onto the invoice. Useful when first-fix invoices to the main contractor under CIS and second-fix invoices direct to the homeowner.
Yes. Flag the job as CIS in your WhatsApp message — Wedge calculates the 20% deduction on labour only (never on timber or fixings you supplied), formats the invoice with reverse-charge VAT wording if both parties are VAT-registered, and prints your UTR in the footer for the main contractor's CIS return.
Heritage joinery (sash window restoration, period skirting reproduction, lime-mortar-bedded oak beams) usually needs detailed materials and labour breakdowns because the customer wants to see what the period-appropriate spec is costing. Just describe each line in the message: "Sash window restoration — 4 sashes — £2,800 labour + £680 materials including period-correct putty and pulleys." Wedge breaks it onto the PDF cleanly.
Yes. Add your qualification and CSCS card number once in the dashboard and they print in the footer of every invoice and quote. Useful on commercial sites where main contractors want evidence of competence, and on residential work for customers checking you're properly qualified.
Set a staged-payment quote — typically 30% deposit, 40% when the carcassing is in, 30% on completion. Wedge holds the schedule on the original quote; you message when each milestone is done and the next invoice goes out automatically. No retyping, no missed stage payments.
Yes — most kitchen fitters work labour-only because the customer buys the kitchen direct from Howdens, Wickes, or B&Q. Just describe the work and your fee: "Invoice Hannah Reid £1,500 for fitting her Howdens kitchen — labour only, customer supplied kitchen." Wedge shows the labour-only nature clearly so VAT and any subsequent disputes are straightforward.
