What is Invoice Aging?
Definition
Invoice aging is a report that groups outstanding (unpaid) invoices by how long they've been past due — typically into buckets: current (not yet due), 1–30 days overdue, 31–60, 61–90, and 90+. It's the standard receivables-health measurement across all business sizes.
Also called an aging schedule or aging report. Appears in accounting software automatically; for spreadsheet users, it's a manual monthly categorization.
Why it matters
- Invoices in the 61–90 day bucket are ~60% likely to get paid; 90+ day invoices drop to ~40%. Aging reveals which invoices are becoming at-risk before they become uncollectable.
- A freelancer with 20% of receivables in the 60+ day bucket has a cash-flow problem masked by the revenue number. Fixing it is a process problem, not a revenue problem.
- Aging patterns differ by client type. Individual customers: mostly current or fully late. Enterprise: predictable 45–60 day AP cycles even on Net 30 terms.
Best practices for Invoice Aging
Review monthly, act at day 30
Run the aging report on the 1st of each month. Trigger follow-up emails for anything entering a new bucket. The day-31 reminder is the single highest-leverage collection move.
Escalate by bucket
1–30: polite reminder. 31–60: firm reminder + ask for ETA. 61–90: escalate to client's AP + consider invoice re-sending. 90+: decision point — collection agency, small claims, or write-off.
Track per-client aging trends
One client who's always 45 days late is a known risk that can be priced for (deposits, shorter terms, late fees). A normally-prompt client slipping to 60 days is an actionable signal that something changed.
FAQ
What's a healthy aging mix?
For most freelancers: 60%+ current, 20–30% in 1–30 bucket, <10% in 31+. 20%+ in 60+ bucket is a cash-flow red flag.
Should I send invoices to collections?
90+ days with no response is usually the threshold. Collection agencies take 25–40% of recovered amounts and damage the relationship. Small-claims court is often better for amounts $2k–$10k depending on state.
