Our expertise

We understand
construction & trades

Construction finance is a specialism in its own right. The CIS, the domestic reverse charge, retentions, project-level costing, and extended payment terms create a financial environment that requires sector expertise — not generic accountancy. Runway works with contractors, subcontractors, developers, and trades businesses across the UK.

The challenges

What makes construction
accounting complex

01
CIS compliance
Monthly CIS returns, subcontractor verification, and deduction reconciliation — the penalties for getting it wrong are significant. We make sure they're filed correctly and on time, every time.
02
VAT domestic reverse charge
The reverse charge fundamentally changes how VAT flows through the construction supply chain. We make sure you're applying it correctly and not creating cash flow problems.
03
Cash flow on long projects
When you're waiting 60 or 90 days for payment on large contracts, cash management is critical. We help you model and manage the gap so you can take on growth without running out of runway.
04
Project-level profitability
Do you know which jobs make money and which don't? We help construction businesses build the accounting infrastructure to understand profitability at the project level.
