Year-End Invoicing Checklist: Timing Tasks Before and After December

Year-end administration often falls behind because it collides with the busy December period, when clients slow down and leftover work piles up. The recommended approach is to sequence tasks: first pursue money that can still be collected before the year closes, then tidy records while there is time to locate missing items. Priorities include billing completed but unbilled work, ranking receivables by age, and separating disputed invoices from merely late ones. Afterward, the focus shifts to checking invoice numbering, storing every issued invoice as a consistently named file, verifying client details, and reconciling partial payments. The checklist is framed as deadlines relative to a business's own year-end, since requirements vary by jurisdiction and entity type.
