Chasing overdue payments is a crucial part of running a business. If cash isn’t flowing, things can go downhill fast. But collecting what’s owed doesn’t have to be a headache if you know what you’re doing. Here’s a rundown of strategies to help you get those unpaid invoices in line and keep customer relationships intact.

Here are some key strategies that will help you tackle overdue payments more efficiently and keep your cash flow on track:

Set Clear Payment Rules from the Start

First things first, get your payment terms straight. Don’t leave any room for confusion. When you start working with a customer, lay out everything—when the bill’s due, how they should pay, and what happens if they’re late. Setting these expectations early on helps avoid future issues and sets the stage for smoother payments.

Use an Aging Schedule

Want to know who owes you and for how long? Use an accounts receivable aging schedule. It sorts unpaid invoices by how overdue they are—whether it’s 30 days, 60 days, or even longer. This lets you see which customers need to be pushed a bit more and where your focus should be. The longer the invoice sits unpaid, the more urgent the action required.

Automate to Save Time

Don’t waste time chasing down payments manually when you can automate the process. Invest in some good invoicing and receivables software. Automating things like sending invoices, follow-up reminders, and overdue notices cuts down on mistakes and ensures no one “forgets” about their outstanding balance. Bonus: including payment links directly in your invoices speeds things up. Make it as easy as possible for customers to pay.

Send Regular Reminders

Timing matters. Don’t wait until an invoice is 60 days overdue to start sending reminders. Start a week before the due date, then follow up again at 15, 30, and 60 days if needed. Consistent reminders keep your invoice top of mind for your customers and increase the chances of you getting paid sooner.

Offer Flexible Payment Plans

Sometimes, a customer just can’t pay everything at once. Instead of letting the invoice sit unpaid forever, offer a payment plan. Breaking the total into smaller, manageable chunks gives the customer some breathing room and ensures you at least start getting paid back. It’s better than getting nothing.

Reward Early Payments

If you want customers to pay early, give them a reason. Offering a small discount—like 2% off if they pay within 10 days—can encourage faster payments. It benefits your cash flow, and they get a little perk for paying ahead of time.

Keep the Communication Open

Don’t just send out invoices and hope for the best. Stay in touch with your customers, especially when they’re behind on payments. A simple phone call or email can remind them to pay without coming across as pushy. Plus, talking to them directly lets you find out if there’s a reason for the delay, and it might help you work out a solution together.

Document Everything

Keep a record of every email, phone call, or letter you send about overdue payments. If the situation escalates, you’ll need these details. Having a paper trail can also help you resolve disputes if the customer argues they didn’t receive an invoice or reminder.

Know When to Escalate

Sometimes, no matter what you do, the customer just won’t pay. That’s when you need to get serious. Have a plan in place for what to do when payments are seriously overdue. This might mean sending a final demand letter or getting a collections agency involved. While this step can hurt customer relationships, you need to protect your business. Before you escalate, though, consider the customer’s history. If this is a one-off situation and they usually pay on time, it might be worth having a direct conversation to avoid burning bridges.

Review and Adjust Your Strategies

Just because a collection strategy works today doesn’t mean it will work forever. Regularly check in on your processes—what’s working, what’s not, and what needs tweaking? Keep an eye on payment trends, and adapt as needed.

Know the Law

Lastly, make sure you’re on the right side of the law. There are rules around how businesses can collect debts, and breaking them can land you in hot water. Make sure your collection practices comply with regulations, so you don’t accidentally cross any legal lines.
