Accounts receivable isn’t just a line on your balance sheet. It’s cash you’ve already earned but don’t have yet. The longer invoices sit unpaid, the more your business feels the squeeze, even when sales look strong on paper.

The foundation is invoicing quickly. Send invoices the same day work is completed or goods are delivered. Every day you wait to invoice is a day added to how long you wait to get paid. If your payment terms are net 30 and you invoice a week late, you’re really looking at 37 or more days before money hits your account.

Payment terms need to be clear and consistent. Net 15, net 30, due upon receipt. Whatever you choose, spell it out on every invoice and stick to it. Include late fee language even if you don’t always enforce it. Customers prioritize invoices that have consequences over those that don’t.

Make paying you as easy as possible. Accept credit cards, ACH transfers, and online payments. If customers have to mail a check, they’ll do it when they get around to it. If they can click a link and pay in 30 seconds, more of them will. The convenience fee on card payments usually costs less than the time you spend chasing checks.

Run your AR aging report weekly, not monthly. Categorize invoices by how overdue they are. Current, 1 to 30 days, 31 to 60 days, 61 to 90 days, over 90. The older an invoice gets, the less likely you are to collect it. An invoice at 90 days has maybe a 70% chance of full collection. At 120 days, that drops further. Many local bookkeepers can help you set up aging reports that make this review straightforward.

Follow up systematically. Don’t wait until you need the money to start calling. Have a defined process. Send a friendly reminder at 7 days overdue. Make a phone call at 14 days. Send a firmer email at 30 days. Escalate at 45 days. Document every contact. Some customers are simply disorganized and need reminders. Others are avoiding you. You need to know which is which.

Know when to escalate. Some invoices need to go to collections or require legal action. Setting that threshold in advance removes the emotional decision-making. You’ve given them multiple chances. At some point, continued follow-up costs more than the invoice is worth.

Prevention beats collection. Require deposits on large projects. For new customers, consider requiring payment before delivery until they’ve established payment history. Credit applications for significant accounts let you check references and set appropriate limits. You don’t want your biggest receivable to be from your riskiest customer.

If AR management takes more time than you have, invoicing and collections can be handled by someone else while you focus on the work that generates revenue. The businesses that collect well aren’t lucky. They have a system. They invoice fast, follow up consistently, and don’t let problems age into disasters.
