Walking through a storage bay in Missoula last September, I noticed a stack of manila folders thick enough to prop up a ladder. Wesley, a shop owner who has been running crews since the early 2000s, kicked the pile with his work boot and told me that stack represented $142,680 in "someday money." Every one of those files was a completed roofing project waiting on a supplement check from an insurance carrier. In Montana, where the building season is compressed by early winters and unpredictable spring hailstorms, carrying that kind of debt is a recipe for a cash-flow heart attack.
Wesley's frustration is the norm, not the exception. Most contractors treat supplements like an after-the-fact administrative chore. They finish the roof, realize they used four more rolls of ice and water shield than Xactimate predicted, and then start a weeks-long game of phone tag with a desk adjuster in a different time zone. By the time that $1,840 check arrives, the profit margin has already been eaten alive by overhead and the cost of capital.
That number is not theoretical. It shows up as smaller draws, slower material buys, and reps who start cutting price because the checking account feels tight.
The "Pending" folder is a profit killer
Days sales outstanding on supplements starves the very jobs you need to run next week.
When we looked at Wesley's books, his average days sales outstanding for the supplement portion of his jobs was sitting at 46 days. In a high-volume storm season, that lag creates a real bottleneck. You cannot buy materials for the next three jobs because your cash is tied up in a roof you finished six weeks ago.
The problem usually stems from a disconnect between the sales rep's initial inspection and what production actually finds. If your sales team is not trained to spot the hidden supplements (non-code-compliant decking, drip edge details that show up often in Gallatin County, steep-slope safety setup) during intake, you are already behind. According to the BLS occupational outlook for roofers, the trade is getting more specialized, yet plenty of Montana shops still run supplements like it is 2005.
If it lives in a folder, it is invisible
Paper stacks do not sort themselves by carrier, age, or dollar amount. Without a single place to see what is pending, owners guess at cash instead of managing it.
Immediate cash flow levers
Standardize a 45-photo minimum for every job site so adjusters stop rejecting files for weak documentation.
Adopt a supplement-first submission policy before the crew leaves the driveway on key variance items.
Move off manual paper tracking and use a simple digital board so you can see bottlenecks by carrier.
Train reps to flag Montana-specific code requirements on the first inspection, not after tear-off.
Why Montana adjusters ignore your estimates
Cheap is not always the real story. Thin proof is.
I have sat through dozens of trainings where reps swear adjusters are cheap. Often the truth is simpler: the documentation is weak. An adjuster in an office in Texas does not care that you hauled bundles up a 12/12 in a Great Falls wind unless you show metadata-stamped photos that tell the story.
In Wesley's shop, we found that 38% of denied supplements were tied to insufficient proof of necessity. We changed the rule so the lead installer could not call the job done until twelve supplement-heavy photos hit the CRM: re-nailing, mid-rip decking, flashing close-ups, and anything that explains why the scope moved.
Supplement workflow comparison (Montana shops)
| Factor | In-house admin | Sales-led pivot |
|---|---|---|
| Speed | Slow (often 15 to 20 days) | Immediate capture, push before final billing |
| Accuracy | Moderate (depends on who owns it) | Moderate to high when tied to field photos |
| Cost | Salary plus overhead | Commission or bonus on recovered dollars |
| Cash flow impact | High lag | Lower lag when closed before depreciation drags |

Cash flow impact
Third-party supplement firms can be fast and accurate, but most take 12% to 18% of recovered funds. That can still pencil out if your internal backlog is brutal.
The sales-led pivot
Align the person who owns the file with the speed of the check.
For shops in the $3M to $7M range, I see the best results when someone is paid to close the supplement, not just install shingles. If the rep or production manager gets a small percentage of the recovery when it is approved before the final invoice goes out, their incentive matches yours. Cash stops acting like a donation to the carrier's float.
The $12,460 documentation gap
Pre-supplement walks turn missed line items into collected dollars.
On a mid-sized residential job in Billings, we tracked a rep named Ethan. After a pre-supplement walk, he caught $2,342 in missed items before shingles landed. At five jobs a week, that is real monthly revenue that used to evaporate.
This is not about padding. It is about getting paid for real work, including safety-related setup that carriers should cover when it is part of the loss. Complex scaffolding and steep-slope fall protection cost money, and the industry conversation on prevention is clear: OSHA's Stop Falls campaign is a useful reference when you are explaining why certain protection items belong in the file, not just on your credit card.
The 48-hour rule
"Never let a supplement request sit longer than 48 hours after the job is completed. Recency matters for adjusters too. They are more likely to approve while the claim is still warm than three weeks later when their desk has moved on."
Building a scalable workflow
Turn supplements from a cost center into a disciplined profit habit.
To move the needle, you need a boring, repeatable system. A Bozeman shop I worked with ran a Supplement Sprint: short windows, clear owners, and no mystery status. It sounds simple because it is. The hard part is enforcing it when everyone is tired at the end of storm season.
Action Plan
The 48-hour supplement sprint
A four-step rhythm that keeps photos, estimates, carrier calls, and invoicing from drifting into the next month.
Photo audit: production manager clears the 45-photo must-have list within four hours of completion.
Gap estimate: admin builds a supplement-only Xactimate file focused strictly on variances.
Carrier phone blitz: two dedicated hours every Tuesday and Thursday for pending approvals only.
24-hour invoice: once approved, final invoice goes out within a day so depreciation checks are less likely to trail the supplement.
I have seen shops tighten their pipeline just by moving the supplement conversation to the front of the job instead of the end. If your lead flow keeps landing thin-margin work that cannot absorb admin drag, you are often fighting the wrong battle before you ever open Xactimate.
Many owners I coach see close rates improve when they explain the supplement path honestly to homeowners. You look like the person who understands the bureaucracy, not another truck-and-ladder bidder. Before the next big storm cycle, it is worth asking how your intake data looks on day one. Cleaner upfront information makes every photo pack and carrier call easier downstream.
