WIP for Builders: From Guesswork to Financial Clarity

Xact Accounting 30 June 2026

Knowing whether a job is making money while it is still running is one of the hardest things to get a clear read on. More often than not, WIP is the reason.

When Work in Progress is not calculated correctly, your profit swings month to month for reasons that have nothing to do with how the business is trading. One month looks strong because three claims landed together. The next looks weak because the pipeline was full but nothing had been invoiced.

That is not a picture you can run a business on. It is not one that holds up when you put your accounts in front of a bank or an auditor either.

 

What we cover

In this Xact Masterclass we show you how to take the guesswork out of WIP and build genuine financial clarity into your business: accurate, timely numbers you can make confident decisions on, without relying on gut feel or last year’s tax return.

You will learn how to:

  • Calculate WIP correctly and understand what your position is actually telling you
  • Get a true read on your monthly profit and stop the swings
  • Strengthen how your accounts are presented to lenders and auditors
  • Connect WIP to the month-end close and a reporting pack that drives real decisions
  • Build financial clarity that scales as the business grows

 

Who it is for

Builders and construction business owners who want to know their real numbers while there is still time to act on them. If you have ever finished a job and wondered where the profit went, this session is built for you.

Plus a tool you can use straight away. Watch the replay and you will get our WIP Calculator template, so you can put the session into practice as soon as you have finished watching.

Every builder has had the job that felt fine the whole way through, until the final numbers landed and the margin had quietly gone. A static budget cannot keep up with an industry that never sits still. This article breaks down how to build a budget from the bottom up, run a rolling forecast every month, and use forecast cost to complete to spot problems while you still have time to act. It also covers why none of it works without proper WIP accounting.
