What Our Construction Accounting Service Includes
CIS Registration & Returns
Subcontractor verification, monthly CIS returns and deduction records handled correctly.
Reverse Charge VAT
Domestic reverse charge VAT applied correctly across your construction supply chain.
Job Costing & Retentions
Profitability tracked job by job, including retentions held back until final sign-off.
Construction Payroll
PAYE payroll for employed staff alongside CIS treatment for subcontractors.
Cash-Flow & Management Accounts
Reporting that accounts for retentions, staged payments and material costs.
CIS COMPLIANCE
CIS Registration, Verification & Monthly Returns
Under the Construction Industry Scheme, contractors must verify each subcontractor with HMRC before paying them, deduct tax at the correct rate, and submit a CIS return by the 19th of each month covering all payments made. Getting any part of this wrong — a missed verification, a late return, or an incorrect deduction rate — can mean penalties and cash flow strain.
We handle subcontractor verification, prepare and file your monthly CIS returns, and keep the deduction records subcontractors need for their own Self Assessment or Corporation Tax return.

REVERSE CHARGE VAT
Reverse Charge VAT & Construction Bookkeeping
Since March 2021, most business-to-business construction services fall under the domestic reverse charge, meaning the customer accounts for the VAT rather than the supplier charging it. Getting this wrong on an invoice creates VAT errors that are time-consuming to unwind. We set your bookkeeping up to apply reverse charge correctly from the start, alongside day-to-day recording of materials, subcontractor costs and job income.

PAYROLL & JOB COSTING
Construction Payroll & Job Costing
Most construction businesses run a mix of employed staff and CIS subcontractors, and each needs to be paid and recorded correctly — PAYE payroll for employees, and CIS deductions for subcontractors, with the two never treated as interchangeable. We also track costs job by job, so you know whether a contract made money once labour, materials and retentions are accounted for, not just whether the bank balance looks healthy.

Retentions & Cash Flow
RETENTIONS & CASH FLOW
Retentions & Cash-Flow Forecasting
Retentions held back until practical completion or the end of a defects period can tie up a meaningful share of a contract’s value for months. We track retentions owed to you and held by you, and build cash-flow forecasts around staged payments, material costs and CIS deductions, so a healthy order book doesn’t turn into a cash squeeze.
