Three raises, one renegotiation, and the rate card nobody re-read
Northbridge Technical is a composite of the mid-market IT shops we built Lumitide for: about 70 consultants on assignment, rate cards and MSP programs on the client side, Bullhorn in front, QuickBooks and Gusto in back — and a gap between those systems where margin quietly changes shape.
The setup
IT staffing margins live and die on the spread: SIA’s benchmark series has the segment’s median gross margin in the 23–26% band, and Northbridge’s book was right in it. But rate-card businesses have a specific fragility: every placement has its own negotiated pay and bill numbers, both of which change over a long assignment — and they change in different systems, maintained by different people, on different weeks.
What the reconciliation found
Retention raises that never reached the bill rate
Over eight months, three consultants got raises — $3, $3, and $4 an hour — to fend off competing offers. All three were entered in Gusto the same week they were promised. None triggered a client rate conversation, and two of the three assignments had contract language that would have supported one. With employer burden, the three raises cost about $1,900 a month in margin, a number that appeared on no report because each placement was still individually profitable — just three points thinner than anyone believed.
A won renegotiation that never reached invoicing
The account manager did everything right: negotiated a $4/hour bill-rate increase at an anniversary, got it in writing, updated the Bullhorn record. The invoicing template in QuickBooks kept the old rate for four months — about $640 a month given away after it had already been won. Rate drift between contract and invoice is the single most-cited leak in industry revenue-leakage writing, and it cuts in both directions: this one was a raise that never billed, the same mechanism that lets a “temporary” discount become permanent.
An MSP fee priced as if it didn’t exist
One program client deducted a 3% VMS fee from paid invoices — typical for such programs, which generally run 2–3.5% of spend. The fee was real and contractual; the problem was that Northbridge’s quoted margins on that account ignored it, so the account’s “24%” book margin was actually landing near 21%. Roughly $160 a month of the gap counted as recoverable (fee applied to pass-through expenses it shouldn’t have touched); the rest was a pricing correction at renewal.
The fix, week by week
- Week 1: placement-level reconciliation of pay (Gusto) against billed (QuickBooks) against contracted (Bullhorn). Eleven placements flagged; the seven above were the real money.
- Week 2: invoicing rates corrected; client conversations opened on the two raise-eligible assignments — one yielded a $2.50/hour increase within the month.
- Week 3: process change: any pay change in Gusto now requires a matching bill-rate decision (increase, absorb with reason, or escalate) before payroll runs, and net-of-fee margin is the only margin reported on program accounts.
Where it landed
About $2,700 a month in recurring margin, recovered or repriced — 2.1 points on the affected placements, roughly a quarter point on the whole book. On a segment-typical 5–7% net margin, that’s several points of profit for three weeks of back-office work. The deeper change was cultural: margin stopped being the number quoted at placement time and became the number verified every week — which, on a book where every placement’s rates are negotiable and perishable, is the only version of the number that’s true.
