General Ledger — Under 100 People

What This Process Does

The general ledger (GL) is every financial transaction your company has ever made, categorized into accounts. At this size, you have one entity, one base currency (usually), and a chart of accounts with 50–150 accounts total. Every bill paid, every invoice collected, every payroll run, every credit card charge posts to the GL — the GL is the single source of truth for what your company owns, owes, earns, and spends.

The goal at this size is simple: clean categorization, reliable monthly financials, and books that don't embarrass you when a VC or auditor asks to look at them. The risks are equally simple: miscoded transactions that confuse runway math, missing entries that understate expenses, and a chart of accounts so messy that no two months can be compared.

Start Here: ERP•AI Templates

ERP•AI's Small Business Chart of Accounts template gives you 80–100 accounts organized by type (assets, liabilities, equity, revenue, expenses) with sensible US-GAAP naming. Industry-specific variants exist for SaaS, services, e-commerce, and nonprofit. Deploy the closest match, then resist the urge to add accounts. Most bookkeeping problems at this scale come from overly granular CoAs — keep it tight and use dimensions (department, project, class) instead of separate accounts for related spend.
