FAQs About Construction Accounting and Financial Services
What type of accounting is used in construction?
Construction firms usually employ project accounting (sometimes called job costing or contract accounting) in conjunction with broader business financial management. Like standard retail accounting, construction accounting often uses the percentage of completion method, recording revenue and expenses proportionately with site work. This specialist accounting also requires detailed tracking of the Construction Industry Scheme (CIS), complex retention clauses, and work-in-progress (WIP) accounts to protect cash flow.
What are the 7 main types of accounting?
The seven major accounting branches are Financial Accounting, Management Accounting, Cost Accounting, Tax Accounting, Auditing, Forensic Accounting, and Accounting Information Systems (AIS). For UK contractors and developers, Cost Accounting is the most critical operational tool.
How to record construction expenses?
Recording construction expenses requires strict job costing. No longer should outgoings be grouped into generic business accounts. Every expense must be tracked and tied to an active project. This involves assigning direct costs (site materials, subcontractor labour, plant hire, etc.) and a calculated share of indirect business overheads.
What does bookkeeping for construction involve?
Bookkeeping for construction industry firms involves high-volume transaction processing with certain regulatory checks. That means checking subcontractors before payment, applying the correct CIS deduction (20% or 30%), and assigning every expense to a project code.
How does the CIS scheme affect construction accounting?
The Construction Industry Scheme (CIS) dictates that contractors must deduct money from a subcontractor’s payments and pass it to HMRC. This counts as advance tax for the subcontractor. From an accounting perspective, this requires strict monthly reporting. If you are bookkeeping for construction business clients, you must ensure you verify every subcontractor with HMRC, deduct the correct rate, and file returns by the 19th of every month to avoid heavy penalties.
