The extras
Where an extension makes or loses its money
Nobody loses money on the quote they sent. They lose it on the eleven things that got asked for afterwards and never made it onto an invoice. That is the part Traddie is built around.
The extra gets priced and approved before you build it
Raise a variation against the job, price the lines, and send the customer a link. They approve a gross figure on a public page, and that exact figure is what lands on the invoice. No "I never agreed to that" in month four, and no two versions of the same rounding.
- The link is a one-time cryptographic token, not a guessable id
- It expires after 30 days so a stale price cannot be approved months later
- Approved variations become invoice lines rather than a note in your phone
Check the margin before it leaves, not after
Before a quote goes out Traddie runs it against your own cost rates and tells you what is wrong with it: the estimated cost is above the quote value, the margin is under your target, labour is eating most of it, or you have not put any materials in at all. Advisory, so you can send it anyway with your eyes open.
Money in as the work goes out
Take a deposit on the accepted quote, then the final invoice arrives with the deposit already netted off. Long jobs stop being funded out of your own bank account while you wait for a single invoice at the end.
Subcontractors, CIS and the reverse charge
Store each subcontractor with their CIS status, apply the right 20% or 30% deduction with materials excluded per HMRC rules, and produce payment and deduction statements. On qualifying business-to-business work, invoices carry the VAT domestic reverse charge instead of charging VAT to the contractor.
What the job actually cost, while you can still act on it
Materials from receipts and purchase orders, labour from time actually logged on site, against what you billed. The timer proposes the hours and the person who was there confirms them, and no location is ever captured, so it is job costing rather than surveillance of your lads.
Materials ordered, chased and reconciled
Raise a purchase order to a merchant, chase it when it has not arrived, and scan the supplier invoice against it when it does, so what you were charged and what you ordered are compared by something other than memory.
The small things that stop a project leaking
Big jobs are not lost in one decision. They go a hundred pounds at a time, in the gap between somebody asking for something and anybody writing it down.
A variation takes a minute
Price it on your phone in the van, send the link, and get on. The customer approves it on their own time and the number is committed on both sides.
The quote check runs itself
Cost above value, margin under target, labour eating the job, no materials entered, a labour rate still set to zero. It looks before you send rather than after they accept.
Photograph the merchant invoice
Scan a supplier invoice against its purchase order instead of keying it, and receipts go into the job rather than the footwell.
The project remembers itself
Quotes, variations, jobs, purchase orders, invoices and payments all hang off the same project, so "where are we financially" is a page rather than an evening.
Deposit, then final, netted off
The final invoice already knows what was paid up front. Nobody works out the balance twice and gets two answers.
Chasing on a ladder you set
A reminder before the due date, then nudge, firm and final. Late-payment interest and the statutory fee can be added for business customers, because on a commercial job you are entitled to them.
Why UK builders choose Traddie
Construction tax, the way it really works
Building work carries the heaviest UK tax admin of any trade, CIS, the reverse charge. Traddie keeps it correct so you are not unpicking it at year end.
- Apply 20% / 30% CIS deductions automatically when paying subcontractors, with materials excluded per HMRC rules, and generate payment & deduction statements.
- Flag the VAT domestic reverse charge on qualifying business-to-business construction invoices so VAT is reported correctly.
- Invoice in stages against milestones, with deposits tracked so nothing slips through.
- Keep a record per project of quotes, variations, invoices and payments.
- Track rolling turnover against the £90k VAT threshold as you take on bigger jobs.
Prove you are covered before you get on site
Main contractors and commercial clients want your public liability and your cards before they will let you through the gate. Keep them in one place and send one link.
- Store public liability, employers’ liability, CSCS cards, waste carrier registration and trade body membership with their expiry dates, and get a reminder before any of them lapse.
- Send one revocable link instead of emailing the same four PDFs to every new client.
- Nothing on it is labelled verified, because Traddie has not verified it: a row is either checkable, with a deep link to the official register, or self-declared with your own document attached.
- Expired credentials never render. Not on the page, and not in the footer of a quote you send tomorrow.
It is a way to hand over what you hold, not a claim that anybody has checked it for you. Expiry reminders for both

Stage payments, subbies and the reverse charge make builders' cash flow the hardest in the trades. These keep the money moving while you run the site.

Invoice chasing
A reminder before the due date, then nudge, firm and final letters on a ladder you set. Late-payment interest and the statutory fee can be added for business customers.
Quote follow-ups
An unanswered quote gets a polite nudge on day 3 and day 7 without you remembering to send it.
Invoice on completion
Mark the job done and the invoice is drafted from the quote, labour and materials, ready to send.
Calendar feed
Jobs appear in Apple or Google Calendar automatically, so the whole team sees the same week.
Accounting sync
Invoices, payments and expenses land in Xero, QuickBooks, Sage or FreeAgent as they happen, VAT and CIS included.
Review requests
A day after an invoice is paid the customer gets one message asking for a Google review, with your link in it.
Every automation is off until you switch it on, and each one has a test-send so you can see exactly what the customer gets. See how chasing works
