What are accounting methods?

Accounting methods define when revenue and expenses are recognized in financial records: the cash basis recognizes transactions when cash changes hands, and the accrual basis recognizes them when earned or incurred, regardless of when cash is received or paid. For professional service firms, the choice of method affects financial statement presentation, tax timing, and management decision-making.

Key characteristics

• Cash basis: recognize when cash moves

• Accrual basis: recognize when earned or incurred

• Affects financial statement presentation

• Impacts tax timing and planning

• May be required by size or structure

• Should be consistent once chosen

Why it matters for professional service firms

Accounting method choice significantly affects reported results and tax obligations. Cash basis is simpler but can misrepresent performance when billing lags work. The accrual basis provides more accurate period matching but requires more effort. Professional service firms should choose methods based on size, complexity, and stakeholder requirements, understanding the implications of each.

Real-world example

Sarah's firm used the cash basis, but the results were misleading: months with heavy collections looked profitable, while months with heavy work and delayed billing looked unprofitable. Switching to accrual basis: revenue recognized when work is performed, expenses matched to periods incurred. Monthly results now reflect actual performance. The change required more bookkeeping effort but provided accurate information for pricing decisions and performance management. Accrual basis revealed true project profitability previously hidden by cash timing.
