How it works
Building work spans the widest range of any trade — from a single-day garden wall to a multi-month extension. The invoicing needs to match: quick for small jobs, detailed for large ones, CIS-compliant for subcontract work, and stage-structured for longer projects.
Tap a button in the menu — Invoice, Quote, or Job Report. Or send a voice note describing the job, or snap a photo of a handwritten job sheet. TaskDrop handles the rest in about 60 seconds.
TaskDrop shows you a preview. Everything correct? Hit send. A professionally branded PDF arrives on your customer's phone immediately.
Customer pays via their banking app using your sort code and account number — money arrives same day. Or by manual bank transfer. Your records update automatically. Done before you've started the van.
Features
TaskDrop handles all of it from WhatsApp. Tap Invoice in the menu or CIS INVOICE, answer a few questions, and a professional PDF is ready in 60 seconds. Large projects use stage invoicing — quote at the start, raise separate invoices at each stage without retyping customer details.
Automatic CIS deduction on labour — 20% calculated correctly, never applied to materials. Right first time, every time.
Invoice in stages for large jobs — deposit, first fix, second fix, completion. Each invoice linked to the project, customer details carried over.
List labour, materials, plant hire and subcontractors on separate lines. Reduces disputes on large jobs.
Send a detailed quote before the job starts. Convert to invoice when done — no re-entering details, no missing information.
Automatic payment reminders at 7, 14 and 21 days. Handles the chasing on stage payments so you don't have to.
Stage payment due? Your bank details are on every invoice automatically. Customer pays via their banking app — money arrives the same day, straight to your account.
Why it matters
Building projects have the highest average invoice values of any trade — which makes getting invoicing right more important, not less. A professional quote at the start sets expectations clearly. Stage invoices issued promptly maintain cash flow across longer projects.
Disputes on building jobs usually start with vague or late paperwork. TaskDrop's detailed invoicing — separate lines for labour, materials, and plant — gives customers the transparency they need and you the paper trail if anything is later questioned.
Day rates for self-employed builders range from £180–£280 in major cities depending on specialism. Groundworkers, bricklayers, and finishing trades often work on day rate subcontract. Extensions, loft conversions, and new builds are the most common project types on TaskDrop.
