Trade Credit Accounts: How to Open One and Why It's Worth It

What is a trade credit account?

A trade credit account is an agreement between you and a merchant that lets you collect goods without paying at the point of purchase. Instead, the merchant invoices you at the end of each month (or on agreed terms — typically 30 days), and you pay the total balance in one go.

It's not a loan or credit card. There's no interest if you pay on time — it's simply deferred payment. The merchant extends the credit as a business arrangement because they want your repeat custom.

Most tradespeople have accounts at several merchants rather than one. A plumber might have accounts at Screwfix, Wolseley and a local bathroom supplier. You pick up what you need, sign or scan at the counter, and settle everything at month end.

The main benefits for self-employed tradespeople

The cashflow benefit alone makes trade accounts worth having. When a job runs into week three and the customer hasn't yet paid their deposit, you're still buying materials on your own money. With 30-day terms, you can often collect materials, finish the job, invoice the customer, receive payment, and then settle your account — all before the balance is due.

• Cashflow buffer. Up to 30 days between buying and paying.
• Consolidated invoicing. One invoice per month instead of a receipt for every trip. Far easier for bookkeeping and tax records.
• Trade discounts. Some merchants offer account holders better pricing than cash customers — typically 5–10% at independent merchants, variable at nationals.
• Faster checkout. Scan your card, sign, go. No queuing at the till to pay.
• Credit limit flexibility. As your account history builds, your limit usually increases without needing to reapply.
• Digital invoices. Most merchants now provide a monthly PDF or downloadable invoice history — useful for VAT returns and job costing.

What you'll need to apply

Requirements vary by merchant but the following are standard across all of them:

• Business name — your trading name or your own name if you trade as a sole trader under your personal name
• UTR number — your Unique Taxpayer Reference from HMRC, which confirms you're registered as self-employed
• Business address — your home address is fine for sole traders
• Contact details — email and phone
• Trade references — some merchants ask for two (names of suppliers or contractors you've worked with who can vouch for you)
• Consent to a credit check — most national merchants run a soft or hard check on application

If you're brand new to self-employment and have no trade references, say so honestly. Most merchants will approve a low starting limit (£500–£1,000) based on a credit check alone and increase it once you have six months of on-time payments.

Opening accounts at the main merchants

Here's a quick overview of the major merchants and what to expect when applying:

For the nationals (Screwfix, Toolstation), you can apply online in about five minutes. For builders' merchants like Jewson and Travis Perkins, it's worth going in-branch — the branch manager has discretion over terms, and a conversation often gets you a better limit and discount than applying online.

What affects approval

Trade credit is commercial credit, not personal credit. That said, for sole traders there's no legal separation between you and your business, so the merchant's credit check will look at your personal credit file as well as any business history.

Factors that help approval: a clean personal credit history, being on the electoral roll at your business address, having a stable bank account, and providing trade references from known merchants or contractors. Factors that hurt: County Court Judgements (CCJs), recent defaults, or a very short self-employment history with no references.

If you're declined, ask the merchant why. It's not always a credit issue — sometimes it's just missing paperwork. You can also try a smaller independent merchant first to build a payment history, then reapply at the nationals six months later.

Managing the account: paying on time

The golden rule: pay your account on time, every time. Late payment damages your relationship with the merchant, may incur charges (usually 2–3% per month on overdue balances), and can result in your account being suspended mid-job — the worst possible time.

Set up a direct debit if the merchant offers one. Most nationals do. It removes the risk of forgetting and usually qualifies you for a prompt-payment discount. Keep a mental note of your statement date (usually the last working day of the month) so there are no surprises.

Download your monthly invoice statement as soon as it's available and check it against your receipts. Errors do happen — wrong items, duplicate charges, or returns that weren't credited. Raising a dispute before the payment date is much easier than chasing a credit note afterwards.

What happens if you miss a payment

If you're going to be late, contact the merchant before the due date — not after. Most will agree a short extension without charging interest if you get in touch early. If you say nothing and just don't pay, they'll usually suspend your account immediately and may start charging late payment interest (the specific rate is in your account terms — typically 2–3% per month on the overdue amount).

Persistent late payment will result in account closure and potentially a default on your credit file, which will affect your ability to open accounts elsewhere. Treat trade accounts like any other creditor.

Are trade accounts worth it for small traders?

Yes, almost universally. Even if you only spend £500 a month on materials, consolidated invoicing alone saves time — one line in your accounts instead of a pile of receipts. The cashflow benefit compounds when you have multiple jobs running.

The only risk is treating the account as a crutch. If you rely on 30-day terms because your business cashflow is stretched, the monthly bill can become a stressor. Use trade accounts as a convenience, not as a substitute for getting paid by customers on time.
