The New Supplier Pause: A 25-Minute Cash-Protection Routine for UK Founders

Paying a new supplier for the first time is a funny moment. You have probably spent more time choosing a phone case than checking whether the person invoicing you is who they say they are. That is not a criticism. When you run a small business, the to-do list is long and the new supplier is usually the answer to a problem, not a risk to investigate.
But the first payment is also the point where trust becomes real money. A 25-minute pause before you press send is not about turning into a fraud squad. It is about giving yourself a few simple facts so you can pay with confidence — or ask a sensible question before the cash leaves your account.
Grab a timer, a cuppa and the supplier's invoice. Here is the routine.
Start with the legal name, not the logo
A smart website and a friendly email signature are not proof of a business. The free Companies House service is your first stop for any limited company supplier. Search the name on the invoice and check the company number matches. Then look at the filing history.
You are not doing a deep forensic audit. You are looking for obvious wobbles: accounts overdue, a proposal to strike off, a registered office that looks like a mail drop, or a director name that does not appear anywhere on the quote. None of these are automatic deal-breakers, but they are worth a question.
If the supplier is a sole trader, Companies House may not have a record. That is normal. Ask for their trading name, business address and a landline or mobile number. Check the website's contact page and see whether the details line up. Save a screenshot of what you found, with the date. It takes two minutes and gives you a useful record if anything goes wrong later.
The VAT question is smaller than it looks
If the supplier says they are VAT registered, ask for the VAT number and check it with HMRC's online VAT checker. It is free and quick. The checker tells you whether the number is valid and whether the business name matches.
If they are not VAT registered, that is fine for many small suppliers under the threshold. But the invoice should not charge VAT. If someone is adding 20% VAT without a valid number, that is a red flag worth pausing on. Do not be shy about asking for clarification. A genuine supplier will not mind.
Insurance: ask for the certificate, not the promise
“We're fully insured” is a nice sentence. It is not a document. Depending on the work, ask for a copy of the relevant insurance certificate — public liability for trades that visit your premises, professional indemnity for advice or design work, and employers' liability if they have staff.
Check the policy is current and the business name matches. If the work is regulated — gas, electrical, childcare, financial advice — check the relevant register as well. You do not need to become an expert in their trade. You just need to see that the paperwork exists before you rely on it.
Two references, one good question
Ask for two recent customers you can contact. Then ask one specific question: “Did they deliver on time, and did the final invoice match the quote?” Generic praise is easy. A specific answer tells you more.
If the supplier is a freelancer with no formal references, look at their portfolio, LinkedIn or recent work. A short call with one past client is often enough. If they hesitate or cannot provide anyone, note it. It may be a simple admin gap, but it is still information.
Payment terms are where the quiet red flags live
Read the quote and invoice carefully. Does the payment schedule match what you agreed? Is there a large upfront payment to a brand-new supplier? Are the bank details different from the ones on the quote? Has anyone emailed to say the bank details have changed? That last one is a common scam. Always verify bank details by phone using a number you already have, not the number in the email.
Check the account name matches the business name. Be wary of payments to a personal account when you are dealing with a limited company, unless there is a clear written explanation. Keep the quote, scope of work and payment terms in one thread so there is no confusion later. A short written summary of what is included — and what is not — is worth more than a long email chain.
Make the one-page supplier file
This is the part that saves you time later. Create a simple one-page note for each new supplier. Include the legal name, company number, VAT status, insurance expiry date, reference notes, quote reference, payment terms, bank details verified date and anything you want to remember. Store it in your cloud folder or finance app.
Set a reminder to review it once a year, or before you increase your spend with that supplier. It is not bureaucracy. It is a receipt for your own good judgement.
The 25-minute timer
Five minutes on Companies House. Five on VAT. Five on insurance and references. Five on payment terms. Five to write the file. If something does not add up, pause and ask. You do not need to be suspicious of every new supplier. You just need to be curious enough to check the basics before your cash flow does the learning for you.
In 2026, small businesses have enough pressure without avoidable payment surprises. A short pause now is one of the cheapest forms of protection you can give yourself.
