Bookkeeping & payrollAccounts Receivable Follow-Up: Getting Paid Without Becoming the Villain

Why is "just checking in on this invoice" the hardest email in the English language? You did the work. They agreed to the price. And yet you'll rewrite that two-line note four times so it doesn't sound pushy, then decide to send it Monday instead.

Most owners we talk to aren't bad at collections. They're just busy, a little conflict-averse, and doing it from memory. Memory is a terrible collections department.

Here's a system for accounts receivable in a small business that does the remembering for you, keeps the tone friendly, and gets money in the door without turning you into the bad guy in your client's group chat.

What accounts receivable actually tells you

Accounts receivable (A/R) is the money customers owe you for work you've already invoiced. It sits on your balance sheet as an asset, which is a generous word for "money that is currently somewhere else."

A/R matters because revenue on your profit and loss statement doesn't pay rent. If you invoiced $90,000 last month and collected $40,000 of it, your P&L looks great and your bank account looks worried. That gap is the most common reason a business is profitable but has no cash.

How to read an AR aging report

The AR aging report sorts every open invoice by how late it is. QuickBooks Online calls it the A/R Aging Summary, and the standard columns are:

• Current (not yet due)
• 1 to 30 days past due
• 31 to 60 days
• 61 to 90 days
• 91 and over

Read it right to left. The oldest column is where the trouble lives, because the longer an invoice sits, the less likely it gets paid in full. Then look for patterns. Is it one big customer or a dozen small ones? Is a single client in three columns at once?

One caution: the report is only as good as the bookkeeping behind it. If customer payments get deposited without being applied to the invoice they paid, the aging report will show that customer as late when they aren't. Calling a client to chase an invoice they already paid is a special kind of awkward. That's why we tie A/R back to the bank every month as part of reliable bookkeeping.

A follow-up schedule that doesn't depend on your mood

Decide the schedule once, then follow it like a recipe:

1. Three days before the due date: a friendly reminder with the invoice attached and a payment link.
2. Seven days past due: "Just making sure this didn't get buried." Short, warm, invoice attached again.
3. Fifteen days past due: a direct note asking when you can expect payment, copying whoever handles their payables if you know who that is.
4. Thirty days past due: a phone call. Not a fifth email. Calls get answers that emails don't.
5. Forty-five to sixty days past due: pause new work until the account is current, stated calmly and in writing.

Most accounting software can automate steps 1 through 3. That's the best part: the reminders come from the system, so you get to stay the nice person who does great work.

A worked example with real-looking numbers

Say you run a four-person marketing agency billing about $60,000 a month on net 30 terms. Your aging report on the first of the month shows:

• Current: $58,000
• 1 to 30 days: $14,000
• 31 to 60 days: $9,500 (one client)
• 61 to 90 days: $0
• 91 and over: $3,200 (a project from last spring)

Total A/R is $84,700. A quick health check is days sales outstanding (DSO), which estimates how many days it takes, on average, to collect. A simple version is A/R divided by monthly revenue, times 30: $84,700 divided by $60,000, times 30, is about 42 days. On net 30 terms, that means customers are paying roughly 12 days late on average.

Now the to-do list writes itself. Call the $9,500 client this week (one relationship, one conversation). Decide whether the $3,200 is still collectible or should be written off; your bookkeeper records the write-off, and your CPA advises on any tax treatment. If you could get DSO down to 32 days, roughly $20,000 of cash would move from "owed to you" into your bank account. That's a nice month.

Habits that prevent late payments in the first place

The best collections work happens before the invoice goes out:

• Put payment terms, due date and how to pay on every invoice. "Net 30" means less to a busy client than "Due March 14."
• Invoice the day the work is done, or on a fixed day each month. A late invoice teaches clients that timing is flexible.
• Take deposits on larger projects.
• Offer an easy payment method. Every extra step is a reason to do it tomorrow.

When A/R becomes a reporting question

If you're always surprised by your cash balance, the problem may be less about chasing invoices and more about seeing the full picture each month: what you earned, what you've collected, what you owe and what's coming. That's the job of financial clarity reporting, where A/R, cash and the P&L show up side by side so the story adds up.
