What bookkeeping do consultants and agencies need?
Short answer
Service businesses mainly need clean invoicing, time-to-cash tracking, expense categorisation and project profitability reporting. Fixed-fee monthly bookkeeping fits them well.
Detailed answer
Look beyond the total profit
Consultants and agencies need to see which clients and projects generate a margin after staff, freelancers and direct expenses. Retainers, advance payments and milestone billing may not equal revenue earned in the month. Time records and consistent project coding help explain results even where you charge a fixed fee.
Review collections and capacity
Reconcile bank accounts monthly, check overdue invoices and compare project budgets with actual labour and subcontractor costs. Review recurring software spending and reserve for tax. A useful management pack links cash, profitability and utilisation so you can spot slow-paying clients or underpriced work early.
