Start Free on WhatsAppTry it in your head. A real joiner’s voice note:
“Bespoke fitted wardrobe for Mr Patel, MDF carcass shop-built, on-site fit one day, eighteen-fifty all in.”
Joinery is two trades in one — the workshop time you bill differently from the on-site fit, the material cost that varies wildly between softwood and hardwood, the FENSA registration that comes out on every external door and window invoice. Holdfort handles all three from a single voice-note: shop time, site time, materials, scheme number. The customer gets a clean PDF; HMRC gets the right VAT split.
Common joiners jobs on Holdfort
Bespoke fitted furniture
Wardrobes, alcoves, bookshelves — voice-note "shop-built carcass, on-site fit Tuesday" and Holdfort splits workshop time, materials and on-site fitting hours so the quote reflects real cost rather than a single mystery price.
Doors, frames & second-fix
External and internal doors, architraves, skirtings, staircases. FENSA registration auto-prefixes external work; fire-door specs (FD30/FD60 with intumescent and smoke seals) line up correctly for landlord FRA paperwork.
Kitchens & shop-fits
Multi-week installations with stage invoices. Workshop time, delivery, install, snagging — each as its own line, with running totals tracked in the same WhatsApp thread.
Heritage & listed work
Sash windows, panelling, restoration. Conservation specs printed on the invoice; site-survey time billable separately from labour day rate so you’re not absorbing it.
How joiners actually use it day-to-day
A typical bespoke wardrobe job has three cost centres: the workshop (carcass and doors built off-site, materials from your timber merchant), the delivery (sometimes a separate van hire), and the on-site fit (1–2 days plus second-fix tweaks). Customers see a "wardrobe price". HMRC sees a single invoice. Your accountant sees a mess. Holdfort fixes that by emitting one customer-facing PDF (one wardrobe price) backed by an itemised cost breakdown your accountant can run their CIS or VAT calc against. For a joiner doing 25–40 bespoke jobs a year, this is the difference between a tidy April and a panicked one.
Questions joiners ask us
Yes. Set your FENSA number once and it auto-prefixes external windows and doors invoices. The Building Regs notification reference attaches as a note on the same invoice, so the customer has the full compliance trail in one PDF without you having to chase the FENSA portal export.
Yes — voice-note "shop-built carcass, install on site Tuesday" and Holdfort splits workshop time, materials and on-site fitting hours. Workshop overheads (rent, dust extraction, electricity) are real costs that disappear if you only invoice the customer-facing price. Splitting them lets you cost properly and quote profitably.
Yes. Voice-note "FD30 fire door, intumescent strip, smoke seal, certified hinges" and each component appears as its own line. Landlords need this for their Fire Risk Assessment paperwork — a generic "fire door fitted" line gets the FRA bounced back by the surveyor.
Yes — photograph or forward the receipt and Holdfort categorises it (softwood, hardwood, sheet) with VAT split correctly. At year-end the categories help your accountant claim the right capital allowances on tools while expensing consumables in the right tax year.
