Walk into most SMEs and ask for the headcount plan and you'll get a puzzled look — there isn't one. Hiring happens when someone's drowning, holding happens by anxiety, and restructuring happens two years after the numbers first suggested it. For the biggest line on the P&L, that's a remarkable amount of vibes. Headcount planning isn't corporate ceremony; it's three ratios, a demand view, and an annual hour of arithmetic. Here's the working version.
The three ratios that frame everything
Revenue per FTE. Total revenue divided by full-time-equivalent headcount (count the part-timers and regular casuals properly). On its own it's blunt; as a trend against your own history it's the cleanest single signal of whether the team and the business are growing in proportion. Falling revenue-per-FTE across several quarters means hiring outran demand or productivity slipped — either way, a hold-and-investigate signal before the next recruitment ad.
Labour cost as a percentage of revenue. The loaded number — wages plus super, comp, leave and on-costs — against revenue, monthly, on the management page. Every industry has a livable band (your accountant or industry association can benchmark you); the management content is again the drift: two points of labour creep on flat revenue is the silent profit-killer we see most often, and it's visible here a quarter before the annual accounts confirm it.
Capacity utilisation. For service businesses, billable or productive hours against available hours; for others, output against capacity. This is the ratio that times hiring: sustained utilisation above the healthy band (with quality or lead-times sagging) says the constraint is capacity; comfortable utilisation with soft revenue says the constraint is demand — and hiring into a demand problem just converts it into two problems.
Reading the signals together
The ratios answer "hire, hold or restructure" in combination, not isolation:
Hire when utilisation is sustainably hot, revenue-per-FTE is healthy, and the demand evidence is structural (a rolling quarter of stretched lead times, declined work, structural overtime) — not one good month. Then hire ahead of the breaking point by the length of your ramp time: a role that takes three months to productivity, hired at the crisis, delivers relief two quarters late. The capacity-planning maths we've covered — fully-loaded cost, the funding bridge, the 90-day checkpoints — applies to every addition.
Hold when the ratios disagree — utilisation hot but revenue-per-FTE falling (a productivity or pricing problem wearing a busy costume), or demand strong but concentrated in one client (the concentration risk hiring would deepen). Holds should be active: the disagreement gets diagnosed, not just endured. Often the right answer to "we need another person" is a system: the quoting templates, the automation, the process fix that returns half an FTE nobody has to recruit.
Restructure when the shape is wrong rather than the size — the admin-heavy structure of a smaller business persisting into a bigger one, the seniority pyramid inverted by tenure drift, two roles that history created and nothing now justifies. Restructure signals: roles whose outputs nobody can name, chronic bottlenecks at one seat while others idle, and the org-chart-versus-reality gap we've written about. The honest restructure happens years before the crisis version and treats people decently precisely because it isn't desperate — redeployment, retraining and natural attrition do most of the work when there's time; redundancy done lawfully and respectfully covers the rest when there isn't.
The annual hour: a headcount plan on one page
Each year (planning season, alongside the budget), draw the table: current roles down the side, the next four quarters across, and three rows of arithmetic per function — forecast demand (from the budget's drivers), implied capacity need, and the gap. The output is a dated, sequenced view: the Q2 delivery hire, the Q3 admin consolidation, the apprentice intake, the role that gets absorbed at the next departure. Add the loaded cost of each move and the plan reconciles to the budget's wage line — which is the test that it's a plan rather than a wish. Then review it quarterly in five minutes against the three ratios: plans meet reality four times a year, and headcount plans that don't get checked become last year's vibes with formatting.
The deeper payoff isn't precision — forecasts wobble — it's that every headcount decision now happens inside a frame: against ratios, against a demand view, against alternatives. The most expensive sentence in SME staffing is "we just sort of ended up with this team." The plan is how you end up with one on purpose.
