Construction Accounting vs Standard Accounting
Construction accounting has several distinct features that set it apart from standard bookkeeping and accounting.
Construction projects often involve multiple phases and stakeholders, and the revenue and expenses associated with each phase need to be tracked and reported separately through robust management accounts.
Additionally, construction projects often involve a significant amount of upfront investment which needs to be tracked and accounted for.
As a result, construction accounting requires a more detailed and nuanced approach than standard bookkeeping services — it requires specialised bookkeeping software and tools to meet its unique challenges.

What is the Construction Industry Scheme?
The Construction Industry Scheme (CIS) is a set of rules that govern how construction companies and their subcontractors handle taxes and payments.
The scheme covers a wide range of work, including:
-
building,
-
civil engineering,
-
and demolition.
Businesses that are covered by the CIS include contractors and subcontractors who carry out construction work, as well as landlords who carry out construction work on their own property.
Under the CIS, contractors are required to register with HMRC and obtain a UTR number (Unique Taxpayer Reference). Subcontractors also need to register for self employment with HMRC and apply for a UTR number of their own before they can be paid correctly.
Once registered, contractors are responsible for deducting money from payments made to subcontractors and paying it to HMRC on their behalf. Subcontractors are then responsible for paying their own taxes based on the money they have received.
We can help you to navigate the CIS and ensure compliance with the rules. We can assist with registering for a UTR number, self employed registration, calculating and making deductions, preparing and submitting returns, and resolving any challenges that may arise — including helping you if you've lost your UTR number or need to find your UTR number quickly.
We can also advise on how to minimise tax liability and claim any available tax reliefs.
Work-In-Progress (WIP)
Work-In-Progress (WIP) in construction refers to the value of unfinished work on a construction project. It represents the costs incurred on a project to date, including materials, labour, and overhead expenses that have not yet been billed to the customer or recognised as revenue.
In accounting, WIP is considered a type of inventory and is typically reported as a separate line item on the balance sheet.
The amount of WIP can fluctuate depending on the stage of the project and the amount of work completed.
WIP is important in construction accounting because it provides an indication of a project's financial performance.
It allows construction companies to track progress, identify potential issues, and make adjustments to ensure the project stays on budget and on schedule.
WIP is also used to calculate the percentage of completion of a project, track the costs incurred on the project, and accurately bill the customer for those costs.
This can be done in different ways, depending on the contract type.
For example, some contracts are based on actual costs incurred, and others are based on fixed-price contracts.
