Your premium was set on a guess.
Payroll, class codes, subcontractors: every exposure figure on your policy was an estimate the day you signed it. Twelve months later an auditor arrives with the real ones, and the invoice follows. Counterline holds the record of your exposure, recomputes the audited premium against it, and documents each variance with the rule that produced it.
The auditor arrives with a record. You arrive with a spreadsheet.
Roughly six in ten workers' compensation audits end in an additional premium charge, three in ten in a refund, one in ten in no change at all [1]. The refunds are the interesting number: nobody chases them, because nobody has the figures to ask.
02
A subcontractor without a certificate becomes your payroll, eleven months late.
At audit, labor paid to an uninsured subcontractor is reclassified onto your payroll at your own class rate [5]. The work was done in March. You find out in February, at your rate, with interest on the delay.
03
You have weeks to dispute it, and nothing to dispute it with.
Audit disputes turn on payroll allocation, class code assignment, subcontractor charges and missing documentation [6]. Without a dated record of exposure that existed before the invoice, you are arguing recollection against a worksheet. So you pay.
Divergence begins with the copy. Counterline removes the copies.
Your broker keeps a list. Payroll keeps another. Operations keeps a third in a shared sheet that stopped being a reference the moment a second person opened it. Counterline keeps one register, and every entry is timestamped, signed and immutable. A correction is made by reverse entry, never by rewriting.

5645 / 8810
$4,200,000 est.
Estimated payroll per the signed application. Locked as the deposit basis, never edited afterwards.

Crew reclassified
Framing crew, 6 heads
5403 to 5645
-$18,400
Residential carpentry separated from commercial framing on the payroll ledger. Rate differential applied from the effective date, not the discovery date.
05/02/2026
Certificate expired
Vendor 214, drywall
5645
$152,000 at risk
Certificate of insurance lapsed while an open purchase order was running. Flagged the day the invoice was coded. The exposure is live from that date until a valid certificate is filed.
06/11/2026
Certificate filed
Vendor 214, drywall
5645
-$152,000
Valid certificate received covering 05/02 to 12/31. Exposure closed. Both the flag and its resolution remain visible in the register.
08/29/2026
Reverse entry
Payroll batch 31
8810
-$41,600
A clerical batch was posted twice. The first entry is not deleted: it is reversed, dated, and signed. What an auditor sees is the correction and its reason, which is the only version that survives a dispute.
11/30/2026
Open claim reserve
Claim 2026-0074
Mod exposure
An unsettled reserve carried at full value into the experience modification calculation, visible before the promulgation date rather than after it.
Four lines decide most audit invoices. Price them yourself.
The four adjustments are recomputed in the browser under NCCI conventions. No value typed leaves the page, and each amount carries the rule that produced it.
Priced against the premium at stake, not against your headcount.
Per-employee pricing measures the wrong thing. Counterline is indexed on audited premium, because that is what is exposed. On a $2,000,000 program, a $28,000 subscription is 1.4% of premium against a range of adjustment risk the industry itself puts between 0 and 18%[3][2].
