Accounting Firm Wallet Estimator - Revenue & Client Intelligence

If an entrepreneur "adopted" this product today, here's the realistic math.

Fermi summary

Get 40 sales teams paying $100/mo and you're at $48k ARR - but the market is so narrow that 40 customers might be 5% penetration of your realistic ceiling, and you'll spend more getting there than you'll earn back in year one.

Go-to-market motion

Outbound LinkedIn to Sales Ops / VP Sales at ~500 companies selling B2B into accounting vertical - target practice mgmt, payroll, tax software vendors - 20 demos/month → 3-4 closes/month at $100-150/mo.

Key risks

Accounting firms are unusually opaque about revenue and client counts - if wallet estimates are wrong by >30%, the core value prop collapses and word spreads fast in a small market
TAM exhaustion: the total universe of motivated buyers may be 800-1,200 companies, not 4,000 - you could hit a ceiling at $80k ARR with nowhere left to grow
ZoomInfo, Bombora, or Grata could ship an accounting-vertical wallet filter as a feature update, making a standalone tool redundant overnight
