Key takeaways

• Trade debtors (known as accounts receivable in the US) are the amounts customers owe your business for goods or services you've already delivered on credit.
• They appear on your balance sheet as current assets because they represent cash you expect to collect within the next 12 months.
• Managing trade debtors closely helps you maintain healthy cash flow, reduce the risk of bad debts, and keep your business running smoothly.
• You can measure how quickly customers pay by calculating debtor days, which divides your trade debtors by annual net sales and multiplies by 365.

What are trade debtors?

Trade debtors is a term used in the UK and Australia for the money customers owe your business after you've provided goods or services on credit. In the US, the same concept is called accounts receivable. Both terms refer to the short-term amounts owed to you as part of normal business operations.

When you send an invoice with payment terms (for example, "due in 30 days"), the unpaid amount becomes a trade debtor on your books. These amounts sit on your balance sheet as current assets because you expect to collect them within 12 months.

Here's a practical example. Say you run a landscaping business and complete a $2,000 project for a commercial client. You send an invoice with 30-day payment terms. Until that client pays, the $2,000 is recorded as a trade debtor. Once the payment clears, it moves from accounts receivable into your cash balance.

Trade debtors vs trade creditors

Trade debtors and trade creditors are 2 sides of the same transaction. Understanding the difference helps you see where your business sits in every deal.

Trade debtors are the customers who owe you money. Trade creditors (called accounts payable in the US) are the suppliers you owe money to. Every credit sale creates both: the seller gains a trade debtor, and the buyer takes on a trade creditor.

For example, if you sell $5,000 of consulting services to a client on 30-day terms, that client is your trade debtor. At the same time, your client records you as their trade creditor. On your balance sheet, trade debtors appear as current assets; trade creditors appear as current liabilities.

Why trade debtors matter for your business

Keeping a close eye on your trade debtors is one of the most important things you can do for your business's financial health. The money sitting in accounts receivable is cash you've earned but can't use yet, and that gap directly affects your ability to pay bills, invest, and grow.

When customers pay late, your cash flow tightens. You may need to dip into savings, delay your own payments to suppliers, or turn down new opportunities simply because cash is tied up in unpaid invoices. Over time, some overdue amounts may become bad debts that you can never collect.

According to Xero Small Business Insights, US small businesses waited an average of 7.8 days past the due date for payment in Q4 2025. That's down from 9.3 days in Q1 2025 and is the shortest late payment period since Q4 2021. The average time to be paid also dropped to 27.9 days, down from 29.2 days in Q1 2025.

These improvements are encouraging, but even a week of late payments can strain a small business's cash position. Tracking your trade debtors regularly helps you spot slow payers early, follow up before invoices become significantly overdue, and forecast your cash flow more accurately.

How to calculate debtor days

Debtor days (also called days sales outstanding) tells you the average number of days it takes your customers to pay. It's a useful measure for understanding how efficiently you're collecting what you're owed.

The formula is:

Debtor days = (trade debtors / annual net sales) x 365

Here's a worked example. Suppose your trade debtors total $45,000 and your annual net sales are $540,000. Plug those numbers in: ($45,000 / $540,000) x 365 = 30.4 days. That means, on average, your customers take about 30 days to pay.

A lower number is generally better because it means you're collecting cash more quickly. What counts as "good" varies by industry, but if your debtor days are consistently higher than your stated payment terms, it's a sign that customers are paying late and you may need to adjust your collection process.

5 tips for managing trade debtors

Staying on top of your accounts receivable doesn't have to be complicated. These 5 steps can help you collect payments faster and keep your cash flow healthy.

1. Set clear payment terms upfront

Before you start any work, agree on payment terms with your customer. Include the due date, accepted payment methods, and any penalties for late payment directly on your contract or proposal. When expectations are clear from the beginning, there's less room for misunderstandings down the line.

2. Send invoices promptly

The sooner you send an invoice, the sooner you can expect to be paid. Aim to invoice as soon as you deliver goods or complete a service. Using Xero's online invoicing lets you create and send professional invoices in minutes, and your customers can pay directly from the invoice with online payments.

3. Run credit checks on new customers

Before extending credit to a new customer, take a few minutes to check their payment history. A simple credit check can flag potential risks before you deliver goods or services on credit. For larger orders, consider asking for a deposit or partial upfront payment to reduce your exposure.

4. Follow up on overdue payments

Don't wait until an invoice is weeks overdue to take action. Set up a system for sending reminders as soon as a payment passes its due date. Xero's automatic invoice reminders can handle this for you, sending polite follow-ups without any manual effort on your part.

5. Offer early payment discounts

An early payment discount (for example, 2% off if paid within 10 days) can motivate customers to pay ahead of schedule. While it slightly reduces your revenue per invoice, the improved cash flow and reduced collection effort often make it worthwhile, especially for high-value accounts.

What to do if a customer doesn't pay

Even with strong processes, some invoices will go unpaid. Having a clear escalation plan helps you recover what you're owed without damaging the customer relationship unnecessarily.

Start with a friendly reminder. Sometimes invoices get lost or overlooked, and a quick email or phone call is all it takes. If the payment is more than 30 days overdue, send a formal written notice that references the original invoice, the amount due, and a firm deadline for payment.

If the customer still hasn't paid after your written notice, consider offering a payment plan. Breaking the balance into smaller installments can make it easier for the customer to pay and more likely that you'll recover the full amount. Document any payment arrangement in writing.

As a last resort, you may want to consider your options for debt recovery, such as engaging a collection agency or seeking professional legal advice on next steps. Before pursuing formal recovery, weigh the cost against the amount owed. For smaller debts, you may want to speak with your accountant about writing the amount off as a bad debt and adjusting your credit policies going forward.
