What Is a WIP Schedule and Why Does Your Surety Company Need One?
If you are a general contractor in New Jersey and you have ever applied for a bond — or tried to increase your bonding capacity — you have almost certainly heard these words from your surety agent: “We need a WIP schedule.” And if your bookkeeper had to ask what that was, you were not ready for that conversation.
A Work-in-Progress schedule — a WIP schedule — is one of the most important financial documents a contractor can produce. It tells your surety company, your bank, and your CPA the true financial status of every job you are currently working on. Not just what you have billed. Not just what you have collected. But where each job actually stands against your original estimate, and whether you are ahead of or behind schedule on recognizing that revenue.
A WIP schedule breaks down each active job and shows several key figures side by side. For every job you are running, it shows the original contract value, the estimated total cost to complete the job, how much cost you have incurred to date, and what percentage of the job is complete based on those costs. From that percentage, it calculates how much revenue you should have earned by now — called earned revenue — and compares that to how much you have actually billed. The difference is either an underbilling or an overbilling, and that number matters enormously to a surety company.
Your surety company is essentially your financial guarantor. When they bond a project, they are telling the project owner that if you fail to complete the work, the surety will step in. That is a massive financial risk for them. Before they take that risk — and before they increase your bonding line — they need to know you are not hiding problems inside your current jobs.
A contractor who is heavily overbilled is a red flag. It means you have already collected money for work you have not yet done. If a job goes sideways and you cannot complete it, the surety is on the hook. A contractor who is heavily underbilled might look conservative, but it can also signal cash flow problems — you are doing the work but not collecting, which means you may be financing the project with your own money and slowly running out of runway.
The WIP schedule lays all of this out clearly. There is nowhere to hide. That transparency is exactly what surety companies need to make their decision.
Here is the hard truth: the majority of NJ contractors I meet who are running under $10 million in revenue cannot produce a WIP schedule on demand. Their books are set up like a retail store’s — cash in, cash out, profit at the end of the year. There is no job-level cost tracking, no earned revenue calculation, and no real-time view of whether their active jobs are profitable or heading toward a loss.
This is why so many contractors hit a ceiling on their bonding capacity. The surety wants to write a bigger bond. The contractor wants more work. But without a clean WIP schedule backed by proper job cost accounting, the surety cannot responsibly increase their exposure. The contractor stays stuck.
Producing a proper WIP schedule requires three things: accurate job cost tracking in your accounting software, a consistent method for estimating percentage of completion, and a bookkeeper or accountant who understands construction accounting and knows how to pull these numbers together in the right format.
