How it works

1. Review the company

We check Companies House details, filing dates, tax registrations, records and any work already in progress.

2. Agree the scope and fee

You receive a written proposal showing recurring services, exclusions and the monthly price before deciding.

3. Onboard or switch

We arrange authorisations and, when switching, request professional clearance and available records from the previous accountant.

4. Run the filing calendar

Records, approvals and deadlines follow an agreed timetable, with questions raised before a return is due.

Specialist guidance

Accounting for construction companies

Construction business accounting should connect estimates, applications for payment, retentions, subcontractor invoices, payroll and project costs to the bank and ledger. That gives directors a clearer view of margin and prevents year-end accounts being built from incomplete job records.

Construction Industry Scheme

A contractor may need to verify subcontractors, make the correct deductions, submit monthly CIS returns and provide deduction statements. Subcontractors need complete statements so deductions can be offset correctly. Duties depend on the role the business performs, not simply whether it describes itself as construction.

VAT and the domestic reverse charge

The VAT domestic reverse charge can apply to specified construction services between VAT-registered businesses where the supply is reported under CIS. The customer accounts for VAT instead of the supplier charging it. End-user and intermediary-supplier rules mean invoices and confirmations need careful review.

Project bookkeeping and cash flow

We separate labour, materials, subcontractors, plant and overheads consistently, then reconcile CIS and VAT control accounts. Project reporting can highlight margin erosion, retentions and tax cash requirements before the year end, while statutory accounts remain grounded in reconciled records.
