What the monthly close has to prove

  • Match invoices and collections to customers.
  • Separate retainers, deposits, earned fees, and reimbursable costs.
  • Track contractor and direct project costs consistently.
  • Review aged receivables and project profitability.

Documents to collect

  • Customer invoices
  • Bank and card statements
  • Contractor bills
  • Payroll reports
  • Payment processor reports
  • Project or time-tracking summary

Common failure points

  • Customer deposits recorded as earned revenue too early
  • Contractor costs buried in general expenses
  • Unapplied customer payments
  • Owner reimbursements mixed with business expenses
  • Old receivables left open

Example

A $12,000 retainer may be cash received before all related work is earned, depending on the contract and accounting method.
