Turnover can be a brilliant confidence trick. A large payment lands, the bank balance looks healthy for twenty-four hours, then suppliers, subcontractors, wages and tax take their share. What remains may be far less than the job appeared to earn.
Construction job profitability is not about producing a corporate dashboard with fifty charts. It is about answering one useful question: after every real cost, was this project worth the time and risk?
1. Start with the final job value
Use the amount you were actually entitled to invoice, including approved variations. Do not include VAT as revenue where it is collected on behalf of HMRC, and do not confuse money received with money earned if an invoice is still outstanding.
2. Add every direct cost
Record the materials, employee labour, your own working time, subcontractors, plant, skips, delivery, parking and other project-specific costs. Small missing purchases can become a large total across a long job.
Use actual figures from receipts, timesheets and supplier invoices rather than the amounts you originally estimated.
3. Include the time nobody sees
Site visits, quoting, collections, client calls, scheduling, snagging and chasing payment all consume capacity. If you only count the hours spent holding tools, some jobs will look far more profitable than they really are.
Track this non-site time against the job where practical. It is particularly important for projects with demanding coordination or repeated client changes.
4. Give overheads somewhere to live
Your business overheads must be recovered across the work you complete. Decide on a sensible method, such as an allowance within the labour rate or a share allocated to each job.
Without overhead recovery, the job calculation may show a profit while the business as a whole still loses money.
5. Compare estimated and actual performance
Look at where the job moved away from the quote. Did labour overrun? Were material quantities too low? Did a subcontractor cost more than expected? Were variations recorded and charged? Did rework or delays consume the contingency?
The purpose is not to blame the team. It is to improve the next estimate and identify risks earlier.
6. Compare job types, not only individual projects
Group similar work and look for patterns. You may find that smaller repairs produce a strong return with fast payment, while larger renovations create impressive turnover but weak margin and months of coordination.
This information helps you choose better enquiries, adjust minimum charges, change suppliers and focus marketing on work that suits the business.
7. Review jobs regularly, not once a year
Check live costs during longer projects and complete a short review when each job closes. Waiting for the year-end accounts is too late to correct a pricing problem that has already been repeated ten times.
Tradeways connects jobs, proposals, schedules, time tracking, contractors, invoices and financial information, helping small trade businesses see the story behind the turnover without drowning in enterprise-level reporting.
