New Fireside Chat with Ian Mizon: Why Contractors Struggle to Scale (and What Actually Fixes It) Watch now
Invoices that
don't gather dust.
Generate an invoice from the completed job — labour, materials, time, expenses, mileage, all already there. Send from your own branded domain. Sync to Xero automatically.
Trusted by 1,500+ UK contractors
From two-person crews to 200-strong firms.
The problem
Chasing invoices by text?
Re-keying job data into Xero?
Customers ignoring noreply@?
The faster you invoice, the faster you're paid. PaperDrop invoices generate from the job itself — costs already in, customer details already in, Xero-synced, delivered from your branded domain. Cash flow that doesn't depend on Friday-night admin.
In plain English
What is contractor invoicing software?
Invoicing software for contractors generates customer invoices directly from completed jobs — pulling in labour, materials, mileage and expenses without retyping — and sends them out under your own brand. For UK contractors that means full two-way Xero sync, payment plans for staged or rolling contract billing, custom-domain email delivery, and live delivery/bounce tracking. The result: invoices that arrive faster, get opened more often, and get paid sooner.
What's inside
Send. Sync.
Get paid.
Job-based invoices
Generate the invoice from the job. Labour, materials, time, expenses and mileage already there.
Two-way Xero sync
Invoice in PaperDrop, see it in Xero. Payments sync back. CIS-compliant.
Custom domain delivery
Send invoices from accounts@yourcompany.co.uk — not a generic noreply. Better open rates, more trust.
Delivery tracking
See opens, bounces and delivery confirmations. Know when the invoice landed and when it didn't.
Bounce alerts
Email bounce? PaperDrop tells you immediately so you can chase the right address before the bill ages.
Payment plans
Stage payments — deposit, milestone, completion — and rolling contracts. Automated invoicing per plan.
How it works
Job done.
Invoice gone.
01
Job complete
Engineer marks the job done on the mobile app. Time, materials, expenses, mileage already captured against the job.
02
Generate the invoice
One click generates a branded invoice with every cost line, customised terms and your VAT details. Edit if you need to; send when you're happy.
03
Send + sync
Invoice goes from your custom domain to the customer. Same record syncs to Xero. Payment lands in Xero, status updates in PaperDrop.
From job done to invoice sent.
The invoice you send is built from the job — engineer hours, parts allocated, mileage logged, expenses approved. No copy-paste from a spreadsheet, no missed line items. The customer sees exactly what they're being billed for.
Send from your own brand.
Deliver invoices, quotes and POs from yourname@yourcompany.co.uk instead of a generic noreply. Better open rates, no spam folder, and a clear chain of trust — with delivery tracking and bounce alerts when emails don't land.
Stage payments and contracts, sorted.
Offer customers a deposit-and-completion plan, milestone-based billing, or rolling monthly contracts. PaperDrop automates the schedule, raises each stage invoice on time, and tracks payment progress against the plan.
“Manual work slowed us down—PaperDrop solved that gap.”

Set up a payment plan on the job — stage payments (deposit/milestone/completion) or rolling contract billing with start and end dates. PaperDrop generates each stage invoice on the scheduled date and tracks payment against the plan.
