How to build an annual operating budget as Professional Services Founders
Your annual budget lives in a Google Sheet that one senior consultant built two years ago and that you're afraid to touch. You copy last year's tab, manually paste in QuickBooks actuals you export every quarter, and try to remember whether that $18k 'other expenses' line was a one-time thing or a real run rate. Utilization assumptions are guesses. Subcontractor costs change mid-year and never get reflected back in the model. By Q3 the budget is so stale it's useless, but rebuilding it from scratch costs a weekend you don't have. You have no finance hire. The spreadsheet is the finance hire.
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 QuickBooks data on a schedule (invoices, bills, vendors, payments, journal entries) and your Stripe data on a schedule (charges, invoices, subscriptions). Starch syncs your Plaid bank account data on a schedule for cash balance and transaction-level actuals. HubSpot pipeline data is queried live from Starch's integration catalog when your revenue forecast needs deal-stage weighting. All four connections wire into the Budgeting, Scenario Analysis, and Transaction Insights apps.

Meridian Advisory's founder connects QuickBooks (scheduled sync), Stripe (scheduled sync for retainer invoices), and Plaid (scheduled sync for the operating account) on a Sunday afternoon. Starch reads 14 months of QuickBooks actuals and auto-suggests budget allocations: it picks up that subcontractor spend averaged $14,200/month last year, with two spikes to $28k in Q2 and Q4 when Meridian staffed up for a large project delivery. The Budgeting app flags this as a pattern and suggests a Q2/Q4 contingency line. The founder adjusts the base subcontractor budget to $15k/month and adds a $25k Q2 contingency. When the Scenario Analysis app runs the 'lose two retainers' downside — two clients at $18k/month each going to zero in June — Starch shows runway dropping from 14 months to 8 months by December, and flags that subcontractor spend would need to drop below $8k/month to stay cash-flow positive. That's the number the founder uses to set contract terms for subcontractor agreements in Q1: no multi-month commitments above $8k without a signed client engagement behind them. Transaction Insights catches a $3,400 charge from a new vendor in February — a software tool a consultant expensed without approval — and flags it in the weekly digest. Total time to build the full FY2026 budget: about three hours, including the scenario modeling.
