Cut Your Trade Debtor Days: 5 Fixes For Wholesalers

Trade debtor days for a wholesale business measure how long, on average, your trade customers take to pay you after you deliver and invoice their order. The five most common reasons they creep up in wholesale are not checking a customer's credit before opening a trade account, unclear payment terms, customers paying late, supply chain problems and paying your own suppliers upfront. Each of these can be fixed with changes to how you open accounts, invoice, deliver and buy stock. This guide explains why debtor days hit wholesalers especially hard, the five causes and how to tackle each one, what the new late payment rules could mean for your business, and how to fund the gap while you wait to be paid. If you need the debtor days formula and worked examples first, our guide on how to reduce debtor days and manage creditor days covers the calculations in full.

Why do trade debtor days matter so much for wholesalers?

Trade debtor days matter for wholesalers because every extra day a customer takes to pay holds back cash you've usually already spent on stock. Wholesale margins are often tight and orders are large, so even a small slip in payment times can leave a big hole in your cash flow. To put a figure on it, divide your annual credit sales by 365. A wholesaler with £1.2 million of annual credit sales has around £3,300 of cash tied up for every extra day its debtor days rise. Ten extra days means roughly £33,000 that isn't available to pay suppliers, staff or the next stock order. Many wholesalers also rely on a handful of large accounts for a big share of their sales. When that's the case, one major customer slowing down its payments can push your whole debtor days figure up on its own, even if every other account pays on time. Seasonal trading can distort the picture too, so compare each quarter with the same quarter last year rather than the one before, otherwise a busy pre Christmas period can look like a sudden collapse in payment times. Our cash flow guide explains how slow payments like these feed into wider cash flow pressure and how to plan for it.

1. Not checking a customer's credit before opening a trade account

Opening a trade account without checking a customer's financial health first is one of the quickest ways to end up with long debtor days and bad debts. A customer who is already struggling is more likely to pay late, ask for extra time or not pay at all, and in wholesale you'll often have shipped a full order before you find out. Before you open a trade account, use a company credit check to find out how reliably the business has paid its other suppliers and whether it has any county court judgments (CCJs) against it. The suggested credit limit in the report is a useful starting point for how much stock you let a new account take on credit, rather than giving every new account the same terms. A few habits help keep your trade accounts under control:

Ask every new trade customer to complete a credit account application with their company number, trading address and trade references.
Set each account's credit limit in line with the customer's typical order size as well as their credit profile.
Recheck a customer before you approve a limit increase or accept an unusually large order.
Keep an eye on how much of your total debtor book sits with any one customer, so a single late payer can't put your whole business under strain.

2. Unclear payment terms

Customers can only pay on time if they know exactly when payment is due. Vague or inconsistent terms give slow payers an easy excuse and can lead to disputes that hold up payment for weeks. Set out your payment terms in your trade account agreement and repeat them on every invoice. Be specific about when the payment period starts. Common wholesale terms such as "30 days end of month" give customers much longer than 30 days in practice. An invoice dated 1 March on those terms isn't due until 30 April, 60 days later, so make sure the terms you offer match the debtor days you can afford. Delivery disputes are the other big cause of delay in wholesale. A customer who reports a short delivery or damaged goods will often hold back payment on the whole invoice, not just the affected lines. Getting a signed proof of delivery for every drop and raising a credit note quickly for any agreed shortfall means the rest of the invoice can be paid on time.

3. Late payments from customers

Even with good credit checks and clear terms, some customers will still pay late. The longer an invoice goes unpaid, the harder it usually is to collect, so acting early makes a real difference to your debtor days. Larger customers, such as retail chains and buying groups, usually pay suppliers on fixed payment runs. If your invoice misses the cutoff for one run, it may not be paid until the next one, which can add weeks to your debtor days. Find out when each of your major customers runs its payments and what it needs on an invoice to approve it, then make sure your invoices reach them in time. Your strongest lever as a wholesaler is the next order. Setting a clear policy in your trade terms that accounts are put on stop once they go overdue, and applying it consistently, gives customers a strong reason to keep their account up to date. It also stops you adding more unpaid stock to a debt that's already late. You also have legal rights when another business pays late, including statutory interest and a fixed sum towards your recovery costs. Our credit management compliance checklist sets out the amounts and the steps to follow when you add a late payment clause to your trade account terms.

4. Supply chain challenges

Supply chain delays push up your debtor days in ways that aren't always obvious. When stock arrives late from your own suppliers, you may have to split orders, send part deliveries or delay invoicing until the full order is ready. Some customers won't pay anything until their complete order arrives, and shortages can lead to lost sales and unhappy customers who are slower to settle what they owe. Reducing your reliance on any one supplier gives you more control. A few steps help:

Use more than one supplier for your best selling or most critical product lines, so a delay from one doesn't stop you fulfilling orders.
Look into the financial position of your key suppliers before you depend on them, as one in difficulty is more likely to miss deliveries.
Agree with customers in advance whether you'll invoice part deliveries separately, so payment for the goods they've received isn't held up.
Tell customers about delays as early as possible, which makes disputes over late or incomplete orders less likely.

5. Paying suppliers upfront

Paying your suppliers upfront doesn't change how quickly your customers pay you, but it makes the impact of long debtor days much worse. In wholesale, you're often funding two waits back to back: the time stock sits in your warehouse and the time customers take to pay once it's sold. If you paid for that stock on the day you ordered it, the whole gap comes out of your own cash. Manufacturers and importers often ask new wholesale accounts to pay on proforma, and overseas suppliers may want a deposit before they ship. Once you've placed a few orders and paid reliably, ask to move onto a credit account. A strong business credit profile and a clean payment record with that supplier both make it easier to secure terms. Where a supplier still wants paying before you've sold the goods, trade finance can pay them directly for a specific order. You then repay once your own customers have paid, so a large stock purchase doesn't drain your working capital.

How will the new late payment rules affect wholesalers?

New late payment rules could help smaller wholesalers get paid faster by large customers such as national retailers. In May 2026, the government introduced the Commercial Payments Bill to Parliament, which it describes as the largest crackdown on late payments in over 25 years. The Bill includes:

A 60 day cap on payment terms when large firms pay smaller suppliers.
Mandatory interest on late payments, set at 8% above the Bank of England base rate.
The Small Business Commissioner would gain the power to investigate poor payment practices, settle disputes and fine the worst offenders.
A requirement for the boards or audit committees of persistently late paying large companies to explain their payment performance publicly.

The rules could work in both directions for a wholesaler. If you supply large retailers, the cap would limit how long they can make you wait. If your own business counts as a large firm, the same cap would apply when you pay smaller manufacturers and producers. The Bill isn't law yet. It started in the House of Lords and still needs to pass through the House of Commons and receive Royal Assent, and the government hasn't confirmed when each measure will start.

How can you fund the gap while you wait to be paid?

Even with tight credit control, most wholesalers will always have some cash tied up in unpaid invoices. The right type of funding can bridge that gap so you can keep buying stock and taking on new orders while you wait. Invoice finance is usually the closest fit, because it releases cash against the invoices you've already raised. Wholesalers can use it in a few different ways:

Invoice factoring advances most of each invoice's value and the provider collects payment from your customers, which can suit a wholesaler without a dedicated credit control team.
Invoice discounting works in a similar way, but you keep control of collecting payment yourself, so your customers deal with you as normal.
Selective invoice finance lets you fund individual invoices, which is useful when one large customer on long terms is the main reason your debtor days are high.

If your cash needs are wider than unpaid invoices, a revolving credit facility offers a reusable limit for stock and supplier costs, and a business loan can fund a larger one off investment such as extra warehouse space. Through our panel of 130+ lenders, you can compare these options side by side and find the one that fits the way your wholesale business trades.
