WIP Schedules and Bonding: What Your Surety Is Really Looking For

For contractors pursuing public work or larger private projects, bonding capacity is a growth ceiling. And that ceiling is set by underwriters who never visit your job sites, they read your financial statements. At the center of that review sits one document: the work-in-progress schedule. Understand what the surety is looking for, and you can build a financial presentation that expands capacity instead of capping it.

Why the WIP Schedule Comes First

A balance sheet tells the surety what you own and owe today. The WIP schedule tells them whether your open jobs will create profit or consume cash over the coming months, which is exactly the risk a surety is underwriting. For every uncompleted contract, a proper WIP schedule shows the contract price including approved change orders, estimated total cost, costs incurred to date, estimated cost to complete, percent complete, revenue earned, billings to date, and the resulting overbilling or underbilling. From those columns, an experienced underwriter can read your company's honesty, discipline, and trajectory.

What Sureties Read Between the Lines

• Profit fade. Underwriters compare each job's estimated final margin across successive statements. Margins that consistently shrink as jobs progress signal weak estimating or poor project controls, and nothing erodes surety confidence faster. Modest, well-explained variances are normal; a pattern of fade is a red flag.
• Underbillings. Revenue earned but not yet billed can be legitimate timing, but persistent or growing underbillings often mean unapproved change orders, claims booked as revenue, or cost overruns hiding in the schedule. Expect pointed questions about any large underbilled position.
• Overbillings and cash. Billing ahead of work performed is fine, sureties like contractors who bill aggressively, but overbillings represent work you still owe. The underwriter checks whether cash on hand supports the obligation, or whether billings from one job are quietly funding another.
• Working capital and equity. Bonding capacity is commonly discussed as a multiple of working capital and net worth, with adjustments that discount doubtful receivables, related-party loans, and other soft assets. Excessive owner distributions right before year-end weaken the very numbers your capacity is built on.
• Consistency. The WIP schedule must tie to the income statement, and the current schedule must reconcile against the prior one. Jobs that appear, vanish, or change history undermine everything else in the file.

The Level of Financial Statement Matters

Sureties calibrate how much they can rely on your numbers based on the level of CPA involvement. Internally prepared statements may support only modest programs. A CPA-prepared compilation adds professional presentation; a review adds analytical procedures and inquiry and is the common requirement as programs grow; an audit provides the highest assurance and is typically expected for the largest programs. Just as important is the accounting method: sureties expect percentage-of-completion accounting with a WIP schedule prepared by someone who understands construction, a generalist financial statement without one tells the underwriter you may be flying blind.

How to Strengthen Your Bonding File

1. Produce a complete WIP schedule monthly, not just at year-end, so surprises surface early.
2. Investigate every significant underbilling and document the cause, timing, change orders pending approval, or a genuine overrun.
3. Keep change orders papered. Unapproved change orders booked as revenue are a classic underwriting objection.
4. Protect working capital: plan distributions with your bonding goals in mind and clean up related-party balances.
5. Deliver statements promptly after year-end. Slow financials read as weak controls.
6. Engage a construction-experienced CPA at the statement level your program requires, and one level of readiness ahead of where you want to be.

Build Capacity Before You Need It

Bonding capacity is built in the accounting department months before the bid is due. The contractors who move up to bigger work are the ones whose financial house was already in order when the opportunity appeared, not the ones assembling paperwork against a bid deadline. Integris Accounting prepares construction financial statements and WIP schedules that sureties trust, and works alongside your bonding agent to position your company for larger work.
