CASE STUDY: CONSTRUCTION — EQUIPMENT STRATEGY & CFO REPORTING
Trucks and equipment were being expensed by instinct, not by strategy
Sentinel Access Systems is a Bay Area security installation contractor generating roughly $3M in annual revenue. Like many field-service and installation businesses, Sentinel relies on a fleet of trucks and specialized equipment to do the work — regular capital purchases that, handled well, can be a meaningful tax-planning lever, and handled poorly, are just an expense that shows up on the books with no strategy behind it.

Gain monthly financial visibility and time equipment purchases for tax benefit
PRIMARY GOAL
The roadblock
Sentinel bought trucks and equipment regularly, but there was no consistent process for deciding what got expensed immediately versus depreciated over time — that decision was being made ad hoc, at tax time, after the fact, rather than as part of a deliberate plan. At the same time, a 15% jump in materials costs from tariffs was quietly compressing margins, and with no monthly financial reporting in place, the owner had no visibility into whether the business was still on plan until it was too late to react.
What we did
01
Built a fixed-asset protocol
Every purchase over $500 now gets flagged for review before it's categorized, replacing guesswork with a consistent rule.
02
Ran an officer compensation analysis
We benchmarked the owner's salary against comparable roles to keep S-Corp payroll defensible.
03
Moved to monthly CFO reporting
We replaced year-end guesswork with a monthly budget-vs-actuals report, giving the owner a real-time read on the business.
What solved it: Turning equipment purchases into a planning tool, not just a cost
The highest-value shift for Sentinel was timing — specifically, flagging two same-year truck purchases as candidates for Section 179 expensing (deducting the full cost immediately rather than depreciating over five years), with the actual election to be made deliberately at tax time against whichever year benefits most. Most equipment-heavy businesses treat depreciation elections as a year-end formality their accountant handles quietly. Treated instead as an active planning decision — made in coordination with monthly financial visibility — equipment purchases become a lever the business can pull deliberately rather than a cost that just happens to them.
The results
2 trucks
flagged as Section 179 candidates, pending final election at tax time
Monthly
budget-vs-actuals reporting, replacing year-end surprises
15%
tariff-driven cost increase now visible and tracked
Where Sentinel felt this most was in the shift from finding out how the year went after it was already over, to knowing where they stood every month — including seeing the tariff-driven cost pressure early enough to respond to it, rather than discovering it in a year-end margin review. The Section 179 election itself is a year-end tax decision that hasn’t been finalized yet; what’s already in place is the discipline that makes the decision possible when the time comes.
"I used to find out how the year went in March. Now I know by the 10th of every month, and my equipment purchases actually work for my tax bill instead of against it."

What worked
The fixed-asset protocol and the monthly reporting worked together: without the monthly numbers, there’d be no reliable way to know which tax year was the “higher-income” year worth timing a Section 179 election against. Without the protocol, equipment purchases would keep being categorized inconsistently, undermining the accuracy of the monthly numbers themselves. The compensation analysis rounded out the picture by making sure payroll stayed defensible while the business worked through a period of real cost pressure. Each piece reinforced the others’ accuracy.
Key takeaways
- Capital equipment purchases can be timed for tax benefit — but only if there’s a system for evaluating them purchase by purchase, not at year-end in bulk.
- Monthly financial reporting isn’t just about visibility for its own sake; it’s what makes proactive tax-timing decisions possible in the first place.
- External cost pressures, like tariffs, are far easier to manage when they show up in a monthly report than when they’re discovered retroactively.
