AR Aging: Why Your Clients Owe You Money and What to Do About It

You did the work. You sent the invoice. And now it's sitting in someone's inbox, unpaid, for 47 days. Meanwhile, you're covering payroll, rent, and supplier costs out of your own cash.

This is the story I hear from at least half my clients. They have revenue. They have profit. What they don't have is cash, because their customers aren't paying on time.

How to Read Your AR Aging Report

Pull it from QuickBooks right now. It buckets every outstanding invoice by age: current (not yet due), 1-30 days overdue, 31-60 days, 61-90 days, and 90+ days.

Here's what healthy looks like. More than 90% of your total AR should be in the current or 1-30 day buckets. If 15% or more is sitting in 60+ days, you have a systemic problem. If anything is over 90 days, the probability of collecting drops to about 70% and falls fast after that.

According to Atradius, 52% of B2B invoices in Canada are paid late. You're not alone, but that doesn't mean you should accept it.

Why Clients Pay Late

Before you get frustrated, understand the reasons. Most late payments aren't malicious.

They forgot. Especially smaller businesses without a dedicated AP person. Your invoice is sitting in a Gmail inbox between 200 other emails.

Cash flow issues. They don't have the money right now. They're waiting on their own clients to pay them. This is the domino effect of bad AR practices across the entire supply chain.

Dispute or confusion. Something on the invoice doesn't match what they expected. Instead of calling you, they just set it aside.

No consequences. You've never followed up, never charged interest, never adjusted terms. They've learned that paying you late has zero impact.

The Collection Process That Works

Here's the process I set up for every client. It's simple, consistent, and effective.

Day of invoice: Send the invoice by email with clear payment terms, amount, and due date. Make it easy to pay. Include a link to an online payment option if possible.

Day 7 past due: Friendly reminder email. "Hi, just a quick note that invoice #1234 for $8,500 was due on March 1. Let me know if you have any questions." Keep it short.

Day 21 past due: Second reminder, slightly more direct. "Following up on invoice #1234, now 21 days overdue. Please confirm when we can expect payment."

Day 30 past due: Phone call. Not email. Call the person who approves payments and have a direct conversation. "I want to make sure there aren't any issues with the invoice. When can we expect this to be resolved?"

Day 45 past due: Formal letter. Restate the amount, original terms, and interest charges if applicable. Mention that continued non-payment may result in service suspension or collections action.

Day 60+ past due: Pause new work for that client until the balance is resolved. This is where most business owners fail. They keep delivering because they're afraid of losing the client. But a client who doesn't pay isn't a client. They're a liability.

Prevention Is Cheaper Than Collections

• Invoice immediately. Don't wait until end of month. Send the invoice the day the work is delivered or the milestone is hit.
• Offer payment options. Credit card, e-transfer, EFT. The easier you make it to pay, the faster you get paid.
• Deposits on large projects. 25% to 50% upfront is standard for projects over $10K. It covers your initial costs and tests whether the client can actually pay.
• Net 15 instead of Net 30. Most small businesses default to Net 30 because that's what everyone does. But if your average client takes 45 days on Net 30 terms, try Net 15. They'll take 30 days, which is what you wanted in the first place.
• Late payment terms in every contract. 1.5% per month on overdue balances. Even if you never enforce it, it signals that you take payment terms seriously.

What to Do This Week

1. Pull your AR aging report. What percentage is over 60 days?
2. Identify your top 3 overdue accounts. Call them. Today. Not email. Call.
3. Set up automated reminders. QuickBooks can send automatic payment reminders. Turn them on.
4. Review your payment terms. If you're on Net 30 and average 50 days, tighten to Net 15.

The Bottom Line

Revenue means nothing if you can't collect it. Your AR aging report tells you exactly where the problems are. Read it monthly, follow up consistently, and don't be afraid to enforce your terms. If your AR is out of control and you need a system, book a free call.
