Accounts receivable

A plain-English guide to accounts receivable for small businesses—the AR process, key metrics, common mistakes, and how to get paid faster.

What accounts receivable is

Accounts receivable (AR) is money customers owe you for invoices you have sent but not yet collected. It is an asset—but not yet cash.

Growing AR can mean growing sales, or it can mean growing collection problems. Aging and trends tell you which.

Every Net-term invoice creates AR. Managing AR is the business side of the invoice-to-cash loop.

The AR process in plain steps

Invoice promptly → deliver payment instructions → remind near due dates → apply cash when paid → follow up on overdue → resolve disputes → write off only when appropriate.

Ownership matters. If “everyone” owns AR, nobody does. Even as a solo freelancer, put a weekly AR block on your calendar.

Tools help, but habits matter more. A simple History review in AI Invoice Generator beats an ignored accounting dashboard.

Key metrics to watch

Total AR, overdue AR, percent current vs late, DSO, and AR turnover. You do not need all of them daily—pick two and track monthly.

A rising overdue percentage with flat sales is a red flag. A rising AR with strong on-time collections may simply mean growth.

Compare against your terms. If you offer Net 15 and your average collection is 45 days, the process is slipping.

Common AR mistakes

Invoicing late, missing PO numbers, not confirming billing contacts, soft-pedaling reminders, and continuing to work for non-paying accounts.

Another mistake: celebrating revenue when it is only billed, not collected. Billings feel good; cash pays rent.

Fix mistakes with checklists on every invoice: contact, PO, terms, pay method, send date, next reminder date.

What to do next

Export or list every open invoice today. Rank by age. Take one action on each overdue item.

Set a rule: no new work for accounts beyond X days overdue without a written plan.

Review AR weekly for 15 minutes—consistency shrinks overdue balances more than occasional heroic chasing.

Key takeaways

  • AR is unpaid invoices—an asset that is not yet cash
  • Invoice promptly and follow a weekly AR routine
  • Track total AR, overdue AR, and collection speed
  • Missing POs and wrong contacts create avoidable AR delays
  • Do not keep delivering to accounts that never pay
  • Treat billed revenue differently from collected cash
