A GMC store isn’t a full-line store. Denali high-line units tote heavier F&I back-end, the commercial book pays fleet flats and minis instead of front-end gross, the service drive runs long Duramax and HD warranty jobs, and the Buick showroom shares the same techs and the same EIN. Generic payroll models none of that, so the office reconciles five pay plans by hand every close. WageTime runs the GMC pay run the way it’s actually built — the high-line commission close, the fleet lane, the diesel true-up, and one run across both franchises.

A GMC rooftop pays nothing like a generic store. Every item below is either hours of unpaid office work at close or a liability compounding quietly while nobody has time to check.
More than 30% of GMC’s 2024 retail mix was Denali and Denali Ultimate — high-ATP units that carry heavier F&I back-end and larger front-end gross. The close isn’t a stack of volume compacts; it’s a handful of big high-line deals, each keyed and rechecked by hand.
GMC’s commercial and Business Elite / GM Envolve book pays fleet consultants on a flat per unit plus volume tiers — volume, not retail gross. That’s a whole comp bucket generic payroll doesn’t model, tracked in a second spreadsheet next to the retail one.
Almost every GMC rooftop is a combined Buick GMC store: one service department, one EIN, techs flagging warranty and customer-pay work across two OEM brands with two warranty schedules. The books still need each franchise’s labor split out — by hand, today.
GMC sells only trucks and SUVs, so the drive skews to Duramax and HD warranty work — long jobs on tight OEM book times. That concentrates the minimum-wage true-up risk on a few diesel techs, and the top-up is owed whether or not anyone did the math.
Only a tech with current GM high-voltage authorization can be paid to flag a Hummer EV or Sierra EV Denali repair order. When authorizations lapse, those flag hours can land on the wrong tech’s check — and nobody’s watching the expiry dates.
Upfit spiffs that clear when the ship-thru completes, fleet dealer cash, aged-unit money, contest cash — they land mid-cycle, and the store still owes correct tax treatment and, often, a check this week, not at the next scheduled run.
Each of these gets a real product screen below, shown with sample store data. The cert ladder and the group-EIN details get straight answers in the FAQ.
A GMC commission close is weighted toward a few back-end-heavy high-line deals, not a wall of volume compacts. In WageTime it’s a screen: gross commissions, unit minis, high-line spiffs, and F&I with chargeback netting compute per person, draw offsets apply against the running balance, and any unreconciled deal rolls forward instead of holding the whole close hostage. You approve a number, not a stack of Denali sheets.
| Salesperson | Units · Denali | Gross comm | High-line spiff | F&I / chargebacks | Draw offset | Net |
|---|---|---|---|---|---|---|
| Brandon L. | 13 · 7 Denali | $9,360.00 | +$1,400.00 | — | −$3,000.00 | $7,760.00 |
| Nadia F. | 8 · 3 Denali | $5,880.00 | +$600.00 | — | −$3,000.00 | $3,480.00 |
| Ivan K. · F&I | — | $14,240.00 | — | −$1,360.00 | −$4,000.00 | $8,880.00 |
| Colby R. | 4 · 1 Denali | $2,040.00 | — | — | −$3,000.00 | −$960.00 carried |
| Tara M. | 9 · 4 Denali | $5,760.00 | +$800.00 | — | −$3,000.00 | $3,560.00 |
Replaces the Denali-by-Denali recheck, the F&I chargeback reconciliation, and the argument that starts with “my sheet says.”
GMC’s commercial and Business Elite / GM Envolve book pays fleet consultants a flat per unit plus volume tiers — a comp bucket that never touches a retail front-end gross. WageTime computes those flats and tiers in the same close as retail sales, so one run pays the showroom and the fleet desk together. Commercial upfit spiffs that clear when the ship-thru completes can run off-cycle at no extra cost.
| Fleet consultant | Units | Flats | Volume tier | Upfit spiffs | Total |
|---|---|---|---|---|---|
| Dana W. | 22 | $3,300.00 | +$750.00 | +$400.00 | $4,450.00 |
| Miguel A. | 17 | $2,550.00 | +$500.00 | +$250.00 | $3,300.00 |
| Owen T. | 13 | $1,950.00 | +$250.00 | — | $2,200.00 |
| Priya N. | 9 | $1,350.00 | — | +$150.00 | $1,500.00 |
Replaces the second commission spreadsheet the fleet desk keeps — and the “was that a flat or a front-end deal?” argument at close.
A combined Buick GMC store is one company with one EIN, and one payroll run pays every tech who flags across both franchises. We import clock and flag hours so there’s no double entry; Buick and GMC warranty ROs book at their own OEM times, land on one run split by brand and by warranty vs. customer-pay, and the finished run posts to QuickBooks mapped by department — no by-hand split.
| Tech | Buick warranty | GMC warranty | Customer-pay | Total flag | Status |
|---|---|---|---|---|---|
| D. Ruiz #05 | 6.2 | 11.4 | 62.9 | 80.5 | Ready |
| K. Tran #10 | 4.8 | 18.1 | 56.1 | 79.0 | Ready |
| W. Boyd #14 | 3.1 | 30.4 | 27.5 | 61.0 | Ready |
| H. Marsh #18 | 2.0 | 9.0 | 31.0 | 42.0 | Ready |
Replaces the two-tab spreadsheet that splits one service payroll across a Buick franchise and a GMC franchise by hand.
Only a tech with current GM high-voltage authorization can be paid to flag a Hummer EV or Sierra EV Denali repair order. WageTime ties EV flag-eligibility to that authorization with an effective date: an expiring credential is flagged before it lands, and hours on those ROs won’t pay to an unauthorized tech. GM publishes no separate high-voltage pay grade — so this is an eligibility gate, not a special rate; each tech’s existing cert-tied flat rate applies. That cert ladder — the GM Center of Learning levels that set flat rates — is the same at any GM store; the EV authorization gate is the GMC-specific piece.
| Tech | HV authorization | EV ROs eligible | Rate on EV ROs | Status |
|---|---|---|---|---|
| D. Ruiz #05 | Current | Yes | $47.00/flag hr | Authorized |
| K. Tran #10 | Expires Sep 30 | Yes | $37.00/flag hr | Renew soon |
| W. Boyd #14 | Training in progress | No | — | Not yet cleared |
| H. Marsh #18 | Not HV trained | No | — | Gas/diesel only |
Replaces the sticky note on the shop board tracking who’s cleared for the EV bay — and the misrouted flag hours when it’s wrong.
GM warranty time books tighter than customer-pay, and a long Duramax or HD warranty job earns few flag hours for many clock hours. Because GMC sells only trucks and SUVs, that drag lands on a few diesel techs. Every period their flat-rate earnings are divided by actual clock hours and tested against the wage floor; a shortfall becomes a documented true-up earning on the run — before the check goes out, not after a claim comes in.
| Tech | HD/diesel hrs | Flat earnings | Clock hrs | Effective | True-up |
|---|---|---|---|---|---|
| D. Ruiz #05 | 12.1 | $3,808.00 | 76.5 | $49.78 | — |
| K. Tran #10 | 26.4 | $2,880.00 | 78.0 | $36.92 | — |
| W. Boyd #14 · diesel | 44.0 | $1,584.00 | 68.0 | $23.29 | — |
| H. Marsh #18 | 8.0 | $945.00 | 66.0 | $14.32 | $144.00 |
| S. Ellison #23 · diesel | 39.5 | $602.50 | 61.0 | $9.88 | $404.00 |
Replaces the by-hand floor check the controller runs on the diesel crew when there’s time — because the liability doesn’t wait for when there’s time.
Yes. The month-end commission close computes gross commissions, unit minis, volume tiers, high-line spiffs, and F&I with chargeback netting per person — the heavier F&I back-end and larger front-end gross a Denali or Denali Ultimate unit carries flow through the same math. Denali and Denali Ultimate ran over 30% of GMC’s retail mix in 2024, so that high-line weight is most of the close, not an edge case.
Yes. A combined Buick GMC rooftop is one company with one EIN, and one run pays everyone who flags across both franchises. Buick and GMC warranty ROs book at their own OEM times; the flag hours land on a single run, split by brand and by warranty vs. customer-pay, so the books show each franchise’s labor without a by-hand spreadsheet split.
Commercial and fleet deals pay a flat per unit plus volume tiers — GMC’s Business Elite / GM Envolve book rewards volume, not front-end gross. WageTime computes those flats and tiers in the same commission close as retail sales, so the fleet desk and the showroom close on one run. Commercial upfit spiffs that land after a ship-thru clears can run off-cycle at no extra cost.
Only a tech with current GM high-voltage authorization can be paid to flag a Hummer EV or Sierra EV Denali RO. WageTime binds EV flag-eligibility to that authorization with an effective date, so an expired credential stops those hours before they route to an unauthorized tech. GM publishes no separate high-voltage pay grade — it’s an eligibility gate, not a special rate, and the tech’s cert-tied flat rate applies.
GM warranty time books tighter than customer-pay, and a long Duramax or HD warranty job earns few flag hours for many clock hours. Because GMC sells only trucks and SUVs, that drag concentrates on a few diesel techs. Each period their flat-rate earnings are divided by actual clock hours and tested against the wage floor; any shortfall becomes a documented true-up earning on the run, before the check goes out.
Yes. Upfit incentives, fleet dealer cash, aged-unit spiffs, and contest money that land between scheduled runs can be paid on an off-cycle run — unlimited runs cost nothing extra — with correct tax treatment applied. You don’t hold the money to the next Friday or push it through as an untracked adjustment.
