BONDING

WHAT SURETIES REQUIRE IN A WIP SCHEDULE.

QUICK ANSWER

Sureties require a current WIP schedule calculated from actual job costing data using the cost-to-cost method. The WIP must show overbilled and underbilled positions by job, projected final margin by job, and the historical accuracy of WIP projections against actual job closeouts. A contractor with 24 months of monthly WIP from ControlQore where projections have consistently matched actual closeouts within 5% will get higher bonding limits and lower collateral requirements than an otherwise identical contractor with no WIP history.

What the underwriter is buying is confidence in your financial statements, and the WIP is where that confidence gets tested. Their question is whether they can trust the numbers, and the answer comes from whether your projections have historically matched your closeouts. A WIP produced for the first time the week of the bonding meeting carries no weight, because there's nothing behind it to check. The same schedule, produced monthly for two years with a track record of matching within 5%, is the single strongest document a subcontractor can bring into that room.

THE DEFINITION

WHAT IT MEANS.

A WIP schedule for a surety is a job by job statement calculated from actual job costing data on the cost-to-cost method, showing contract value, estimated cost at completion, cost to date, percent complete, revenue earned, amount billed, and the overbilled or underbilled position on every open job.

THE FOUR WIP ELEMENTS SURETIES EVALUATE

WHAT THEY CHECK, AND WHAT KILLS IT.

01

Calculation method

What the surety wants is cost-to-cost calculated from actual job costing data, meaning cost to date divided by estimated total cost. The red flag is percent complete estimated by the owner or a project manager with no underlying cost documentation behind it. One is a financial statement and the other is an opinion, and the underwriter can tell the difference in about a minute.

02

Overbilled and underbilled

What the surety wants is the overbilled and underbilled position disclosed clearly by job, with dollar amounts on each one. The red flag is a schedule that doesn't disclose those positions at all, or that nets them into one combined figure. Netting hides the thing they're looking for, because a heavily overbilled job next to a heavily underbilled job is a very different risk than a portfolio that's close to even.

03

Projected final margin

What the surety wants is projected final margin updated from the actual cost trajectory rather than carried forward from the original estimate. The red flag is every job on the schedule still showing its bid margin regardless of how the costs have run. A WIP where nothing ever moves isn't a projection. It's the estimate reprinted with a new date on it.

04

Historical accuracy

What the surety wants is a record of WIP projections finishing within 5% of actual closeout margins. The red flag is a WIP produced for the first time at the bonding meeting, or one built from estimates rather than verifiable cost data. Accuracy is the only element on this list that can't be created in a week, which is why it's the one that moves the limit.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The accuracy standard

The acceptable variance between projection and actual is 5%. A contractor with 24 months of monthly WIP where projections have consistently matched actual closeout margins within 5% gets materially better bonding terms than an identical contractor with no WIP history. The requirement is monthly production, because that's what builds the track record in the first place.

How the limits get set

Sureties set single-project limits at 10-15% of net worth and aggregate limits at 20-25% of net worth. They will go above those ratios for contractors who can demonstrate financial management sophistication, and the WIP track record is how that gets demonstrated. The ratio is the starting point rather than the ceiling.

24 MONTHS OF WIP THAT SURETIES TRUST

HOW THE TRACK RECORD GETS BUILT.

Months 1 to 3, calibration

The cost codes get built to match your estimate structure so the two sides can be compared at all. Variance between projection and actual runs wide in this stretch and that's normal, because the system is still settling and the field is still learning where to post. Nothing here goes to a surety yet.

Months 3 to 6, the projections tighten

Projections start finishing within 10% of actuals as the cost codes stabilize and the crews build reliable posting discipline. Most of our clients reach 5 to 8% accuracy by month 6. This is the point where the WIP becomes useful to the owner, several months before it becomes useful to an underwriter.

Months 6 to 12, the record starts

Now a surety can compare six months of projections against actual closeout margins and check the work themselves. That comparison is the foundation the bonding capacity gets raised on, because it's evidence rather than assertion. Six months is the minimum where the conversation changes tone.

Months 12 to 24, premium limits

Consistent monthly WIP across 12 to 24 months, with projections staying within 5% of actual closeout margins, moves the surety conversation off collateral requirements and onto what limits you want. Same company, same balance sheet, and a different set of terms, because somebody can now verify that your numbers hold up.

COMMON QUESTIONS

FREQUENTLY ASKED.

A current WIP schedule calculated using the cost-to-cost method from actual job costing data. It must show contract value, estimated cost at completion updated from the actual cost trajectory, actual cost to date, percentage complete meaning actual cost divided by estimated total cost, revenue earned meaning percentage complete times contract value, amount billed, and the overbilled or underbilled position by job.
A contractor with 24 months of monthly WIP where projections have consistently matched actual closeout margins within 5% gets materially better bonding terms than an identical contractor with no WIP history. Sureties set single-project limits at 10-15% of net worth and aggregate limits at 20-25% of net worth, and they will go above those ratios for contractors with demonstrated financial management sophistication.
You can produce one, and it won't carry the same credibility. A WIP calculated from actual cost data posted daily by foremen to ControlQore cost codes is verifiable and consistent. A WIP estimated by the owner or the PM with no underlying cost data behind it's not verifiable, so the surety treats it as an estimate rather than as a financial statement.
Monthly. Sureties prefer monthly WIP because it shows active financial management and because it produces the 12 to 24 month track record that increases bonding limits. Quarterly WIP is the minimum most sureties will accept. Annual WIP produced at bonding renewal is a snapshot.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well.
