How to plan headcount as Chief of Staff and Founder's Office
Headcount planning for a chief of staff means stitching together a spreadsheet that no one trusts. You pull actuals from Paylocity or ADP, guess at open-req timing from a Notion hiring tracker that's three weeks stale, cross-reference offer pipeline from a Google Sheet the recruiting lead owns, and then reconcile all of it against the budget numbers the CFO approved in QuickBooks — usually at 11pm before a board meeting. The plan lives in a Google Sheet that breaks every time someone sorts a column. You rebuild it quarterly from scratch. You are not a finance team. You are one person who is also coordinating the exec offsite this week.
What you'll set up
Apps, data, and prompts
The combination of Starch apps, the data sources they pull from, and the prompts you use to drive them.
Starch syncs your Paylocity or ADP data on a schedule for actuals headcount and payroll run-rate. Starch syncs your Plaid transactions and Stripe revenue on a schedule as the cash baseline for scenario modeling. QuickBooks entity data (bills, invoices, payments) syncs on a schedule for budget-vs-actual reconciliation. Open reqs and hiring pipeline data from tools like Greenhouse or Lever are queried live from Starch's integration catalog when your headcount app runs. Notion hiring docs are synced on a schedule so your tracker reflects the latest notes from recruiting.

Q3 2026 headcount plan — 150-person growth-stage company
| Engineering — approved headcount | 42 |
| Engineering — filled seats (Paylocity actual) | 38 |
| Engineering — open reqs (Greenhouse) | 6 |
| Monthly payroll run-rate (engineering) | 612,000 |
| Total company monthly burn (Plaid) | 1,850,000 |
| People cost as % of burn | 71 |
| Runway at current pace (months) | 14 |
| Runway if accelerated hiring plan executes (months) | 9 |
It's the first week of July. You're building the Q3 board deck and the CEO wants a clean answer to 'what does our hiring plan do to runway?' Your Starch headcount tracker shows engineering at 38 filled seats against a 42-person approved budget, with 6 open reqs in Greenhouse at various stages. Paylocity data puts engineering payroll at $612k/month. Total company burn from Plaid is $1.85M/month, so people cost is running at 71% of burn — higher than the 65% the CFO modeled at the start of the year. You pull up the Scenario Analysis app. The baseline (current 38-seat pace, no new reqs) shows 14 months of runway. The accelerated plan — all 6 reqs close by September, plus 4 additional hires the VP of Engineering just requested — drops runway to 9 months and puts the next raise squarely in Q1 2027. You tell Starch: 'Add a fourth scenario that shows what happens if we close only 3 of the 6 open reqs and hold the 4 additional requests until January.' Starch adds it in under a minute. The new scenario shows 12 months of runway — enough cushion to start a Series B process from a position of strength rather than urgency. That's the recommendation you bring to the board. The whole analysis took 20 minutes, not a Sunday.

Does Starch pull actual salary data from Paylocity or ADP, or just headcount?
What if my open reqs are tracked in Greenhouse or Lever, not in Paylocity?
Can I model comp by role, not just by department aggregate?
We use QuickBooks for financials, but the CFO also wants the headcount budget reconciled against department P&Ls. Can Starch do that?
Is this SOC 2 certified? We're a growth-stage company with investors asking about data security.
The scenario analysis sounds useful, but our finance lead built a model in Excel that the CFO already trusts. Why would I replace it?
Can I share the headcount tracker with the VP of Engineering and VP of People without giving them access to everything else in Starch?
