Tracking the subcontracting limit in a spreadsheet.
Most small primes track this in Excel, and on one contract that's reasonable. Here's what the tracker has to contain to be worth anything — and the four things that turn it into a liability during a review.
What the tracker has to contain
| Tab | Columns | Why |
|---|---|---|
| Government payments | Date paid, invoice ref, amount | The denominator — amounts paid, not billed |
| Subcontracts | Sub, amount paid, allocation to this contract, materials portion, SSE yes/no | The numerator, before exclusions |
| Status evidence | Sub, status claimed, how verified, date, evidence ref | The tab that decides whether a sub counts |
| Summary | Counted ÷ paid, against the limit | One number, computed |
The calculation
Counted subcontracting ÷ eligible government payments, compared with the limit for the contract type — 50% services, 50% supplies, 85% general construction, 75% special trade. Materials come out of the numerator on supply and construction contracts, not on services. Measured over the period of performance, not per month. The detail is in the full guide, and you can run your own numbers in the free calculator.
When the spreadsheet is enough
One contract, a couple of subcontractors whose status you verified yourself, no lower-tier subcontracting, and a person who understands the clause maintaining it. That's a real and common situation.
The four ways it fails
- Status is assumed. A sub is marked similarly situated because of their marketing or their certification years ago. If you can't produce dated verification, it counts against you — and the percentage you've been reporting was never right.
- Lower tiers go missing. A similarly situated sub's own subcontracting comes back into your numerator. Almost no spreadsheet tracks it, because nobody asked the sub for the figure.
- Hours creep in. Someone starts tracking labour hours because that's what the workforce report wants. The two are different calculations and mixing them produces a number that answers neither question.
- The evidence isn't attached. The percentage is in the sheet; the payment records, the allocation logic and the verification are in email, in the accounting system, and in someone's memory. When a contracting officer asks on short notice, you're rebuilding, not producing.
THE SAME TRACKER, WITH THE EVIDENCE ATTACHED
SubLimit does this from the exports you already have.
Import payroll, subcontractor and government-receipt files; record verified statuses with their evidence and dates; get the exact percentage with every contribution traceable to its source row, and every unknown listed as an exception instead of a guess. The workforce report draft comes from the same records. Local Windows software, nothing uploaded. $149.00/month, 30-day no-card trial.
Get started ↗Prepare a first review without uploading business records
- Keep the awarded contract and its measurement period beside your worksheet.
- Use a copy of your government-receipt and subcontractor-payment exports; keep the originals unchanged.
- Record missing evidence as an open item, rather than filling it with an assumed value.
- Compare the worksheet with the free calculator, then review the source rows behind each total.
