Real builders jobs, quoted by voice

Single-storey rear extension

Walk the site, voice the groundworks, structural steels, brickwork, roof, glazing and finishes. Fixxa drafts a clean, branded quote in minutes; convert each stage into its own invoice as the build progresses.

Loft conversion with dormer

Quote the strip-out, structure, dormer, plastering, second fix and snagging as separate stages. Take a deposit invoice up front and stage payments at first fix, second fix and completion.

Full kitchen refurbishment

Voice the demolition, plumbing first fix, electrical first fix, plastering, units, worktops and tiling. Send a single quote that the homeowner can review and approve on WhatsApp.

Insurance reinstatement after a leak

Quote the strip-out, drying, replastering, redecoration and any snagging. Branded paperwork helps loss adjusters approve and pay quickly.

Common quoting and invoicing mistakes

One big lump-sum quote

A single price for a £40,000 extension makes homeowners nervous. Break the job into stages with clear scope and pricing so the customer sees exactly what they are paying for at each step.

No deposit before ordering materials

Builders carry too much cash flow risk on materials. Send a deposit invoice with a faster payment link before placing big orders.

Stage payments left to chance

Agree the stage payment schedule in writing inside the quote. Then raise the invoice the day each stage hits, not weeks later.

Vague variations and extras

Verbal extras lead to disputes. Quote variations as their own short voice quote and get sign-off on WhatsApp before you start the work.

Practical workflow tips

  • Quote in stages: enabling works, structure, first fix, second fix, finishes, snagging
  • Send a deposit invoice with a faster payment link before ordering long-lead materials
  • Use a standard variation template so extras are quoted and approved the same way every time
  • Issue stage invoices the day each stage completes; momentum keeps payments on time
  • Keep digital copies of every quote, variation and invoice so your accountant has a clean trail

Trust and compliance

Fixxa does not replace your accountant on CIS deductions, the construction VAT reverse charge or building regulations sign-off. It does keep your commercial paperwork consistent: branded quotes, staged invoices, faster payment links and a digital record of everything to support Making Tax Digital.
