Before You Say Yes: The Hidden Risks of Taking On a New Business Customer

A new customer gets in touch. They have a substantial project, the budget sounds promising, and they want to get started quickly.

For a small business, that is usually welcome news.

Perhaps you have been trying to secure more work for months. Perhaps the contract could help you employ another member of staff, invest in equipment or finally give your business some breathing room.

Everything looks positive.

There is just one question that has not been answered.

What do you actually know about the company that is going to pay you?

You might know what they want, when they want it and how much they are prepared to spend.

But do you know whether they have a reliable payment history? Have you checked their company details? Do you understand their financial position? And, perhaps most importantly, have you considered what would happen if the money did not arrive when expected?

These questions are not about being suspicious of every new customer.

They are about recognising that winning work and getting paid for it are two different parts of running a successful business.

At Will They Pay, we believe businesses should have access to better information before making commercial commitments.

Because sometimes the most valuable decision you make is not whether to accept a contract.

It is deciding what needs to be checked before you accept it.

1. Why a New Customer Can Represent Both Opportunity and Risk

Every new customer brings potential.

More revenue. New relationships. Recommendations. Opportunities for repeat business.

But accepting a contract can also mean accepting financial exposure.

Consider a small building contractor offered a £40,000 commercial refurbishment.

The contractor might need to purchase £12,000 of materials, allocate employees for several weeks and turn down other projects to meet the deadline.

The customer agrees to pay 30 days after completion.

On paper, the contract looks profitable.

In practice, the contractor could be financing a considerable portion of the work before receiving anything.

If payment arrives on time, the arrangement may work perfectly well.

If it arrives 60 days late, the contractor could face difficult decisions about wages, suppliers and future projects.

If it never arrives, the consequences could be much more serious.

This is an illustrative example, but the commercial principle applies across many industries.

The larger your financial commitment to a customer, the more important it becomes to understand the associated payment risk.

That does not mean declining every large contract.

It means making sure the commercial terms reflect the level of risk you are prepared to accept.

2. The Mistake of Confusing a Professional Appearance With Financial Reliability

A polished website can create an excellent first impression.

So can a modern office, a recognisable client list or a confident representative.

None of those things necessarily tells you whether a company pays its suppliers reliably.

A business can look successful while experiencing cash-flow difficulties.

Equally, a smaller company operating from modest premises might have an excellent record of meeting its obligations.

Appearances are not financial evidence.

That is why customer due diligence matters.

Before offering credit, consider checking the company's registered identity, available financial information and relevant payment experiences.

For UK limited companies, Companies House is a useful starting point.

You can investigate information such as incorporation details, filing history, officers and available accounts.

However, Companies House itself makes clear that it does not verify the accuracy of all information filed with it.

Public records are therefore useful evidence, not a guarantee of financial reliability.

The sensible approach is to combine different sources of information rather than relying on one reassuring impression.

3. What Is a Business Credit Check?

A business credit check involves reviewing available information about a company's financial position and credit risk.

Depending on the provider and the information available, a business credit report may include:

Company identification and registration information.

Financial accounts and indicators.

Credit-risk assessments or scores.

Suggested credit limits.

Relevant insolvency or legal information.

Changes in financial or company circumstances.

Available payment-related information.

Not every report contains every type of information, and the depth of available data varies between businesses.

For example, a recently incorporated company may have limited financial history.

A more established business may have several years of accounts available.

The purpose of a credit check is not to predict the future with certainty.

It is to help answer a practical question:

How much financial exposure should we be comfortable accepting with this customer?

A report may help you decide whether to offer standard terms, request an upfront payment or investigate further before proceeding.

This is particularly useful when a new customer is requesting a credit arrangement substantially larger than your business would normally provide.

4. A Credit Score Is Useful, but It Is Not the Whole Story

Imagine two prospective customers.

Customer A has reassuring financial indicators, but several suppliers report that invoices frequently require repeated reminders.

Customer B has a more limited credit history, but available supplier experiences suggest consistent communication and payments within agreed terms.

Which would you choose?

There is no automatic answer.

Customer A may have the resources to pay but operate a slow or complicated payment process.

Customer B may be dependable in its relationships but have less financial capacity to absorb a major unexpected expense.

The important point is that these two customers present different considerations.

A business credit report can provide financial and credit-risk information.

Supplier payment reviews can provide accounts of actual trading experiences.

Neither should be treated as conclusive in isolation.

Financial information and payment behaviour can be more informative when considered together.

This is one of the principles behind Will They Pay.

Our aim is to help businesses make more informed commercial decisions by bringing greater visibility to payment practices.

5. The Five Questions to Ask Before Taking On a New Customer

You do not need a large finance department to establish a sensible checking process.

Start with five questions.

Question One: Are We Dealing With the Correct Legal Business?

Confirm the customer's legal entity, registered details and the name that will appear on your contract and invoices.

Trading names can differ from registered company names.

If something goes wrong, you need to know which legal entity actually owes you the money.

For sole traders and partnerships, the checks may differ from those used for limited companies.

Do not assume that a familiar brand name identifies the contracting party.

Question Two: What Does the Available Credit Information Tell Us?

Review the customer's credit information proportionately to the value and nature of the proposed work.

A small one-off transaction paid in advance may require little investigation.

A £75,000 contract with substantial materials purchased upfront deserves considerably more attention.

Question Three: What Do Other Suppliers Say About Their Payment Behaviour?

Look for relevant, factual payment experiences.

Have suppliers reported payments within agreed terms?

Are there recurring complaints about communication or disputed invoices?

Are there positive reviews describing professional and reliable conduct?

One review should not determine your entire decision.

Look for patterns, dates, context and the quality of the supporting information.

Question Four: Can We Afford the Proposed Payment Terms?

A customer might be financially sound and still request terms that place too much pressure on your own cash flow.

Consider your wages, materials, tax obligations and existing customer commitments.

A profitable project is not necessarily a manageable project if too much cash is tied up for too long.

Question Five: What Happens if Payment Is Delayed?

Before starting, decide how your business would respond.

Would you be able to continue trading comfortably?

Could you negotiate staged payments?

Should you set a credit limit?

Would an upfront deposit reduce the exposure?

The best time to consider these questions is before the money becomes overdue.

6. How Much Could a Late Payment Actually Cost You?

The cost of late payment extends beyond the invoice amount.

Imagine a business has a £20,000 invoice that remains unpaid for an additional 60 days.

If that shortfall forces the business to borrow at an illustrative annual interest rate of 12%, the approximate interest cost over 60 days would be:

£20,000 × 12% × 60 ÷ 365 = £394.52

That is only the financing cost.

It does not include time spent chasing payment, additional administrative work, disrupted purchasing or opportunities lost because working capital was unavailable.

Not every business will need to borrow, and actual borrowing costs vary. Nevertheless, the calculation demonstrates why payment timing has a measurable financial consequence.

The problem becomes more significant when several customers pay late simultaneously.

A company can be generating healthy sales while struggling to meet everyday commitments.

That is why cash-flow management should include an assessment of payment risk before new credit is extended.

7. Better Information Does Not Always Mean Turning Down the Work

One of the biggest misconceptions about credit checking is that it exists to tell you which customers to reject.

In reality, it can help you decide how to structure the relationship.

Suppose a prospective customer wants a £30,000 project but the available information raises some concerns.

You may still want to proceed.

Rather than rejecting the opportunity immediately, consider whether a different payment arrangement would make the project manageable.

For example:

Option A: A deposit

Request an agreed upfront payment to cover part of the initial costs.

Option B: Milestone payments

Divide the project into clearly defined stages, with payment linked to agreed milestones.

Option C: A lower initial credit limit

Begin with a smaller amount of exposure and review the relationship after successful transactions.

Option D: Shorter payment terms

Agree a payment period that better reflects the business's working-capital requirements.

Option E: Payment before delivery

For certain products or services, upfront payment may be commercially appropriate.

These options should be agreed before work begins and documented clearly.

The aim is not to make doing business unnecessarily difficult.

It is to find arrangements that both parties understand and can reasonably support.

8. Why Positive Payment Reviews Deserve More Attention

Payment transparency is not simply about identifying problems.

It should also help reliable businesses receive recognition.

Imagine a customer who consistently pays on the agreed date, raises invoice queries promptly and communicates clearly when something needs attention.

That customer is contributing to the supplier's ability to plan, invest and operate confidently.

It is a valuable part of the relationship.

Yet businesses often spend more time discussing negative payment experiences than acknowledging positive ones.

This is an opportunity to change the conversation.

Positive reviews can help demonstrate what good commercial conduct looks like.

They may also encourage businesses to take pride in their payment reputation.

At Will They Pay, we want transparency to work for good payers as well as businesses trying to avoid unnecessary risk.

Because responsible payment behaviour deserves to be visible.

9. The Clear From the Start Approach

There is another important part of customer due diligence that no credit report can replace.

A clear conversation.

Even a financially strong customer relationship can become difficult if expectations were never properly agreed.

Who approves invoices?

Is a purchase order required?

When should invoices be submitted?

Does the customer operate fixed payment runs?

What happens if work is disputed?

Who should be contacted if an invoice remains outstanding?

These questions may sound administrative, but they can make a considerable difference to how smoothly a relationship operates.

This is the thinking behind Will They Pay's Clear From the Start campaign.

Good business starts with clarity.

The objective is not to create suspicion or pressure.

It is to establish professional expectations from the beginning so that both businesses understand how the relationship should work.

A useful approach is our C.L.E.A.R. framework:

C — Clarify timelines: Agree the project schedule, milestones and payment dates.

L — Log expectations visibly: Keep written records of important commercial agreements.

E — Establish payment processes: Confirm invoicing requirements, payment methods and approval procedures.

A — Align communication early: Agree who handles queries and how they should be raised.

R — Review on Will They Pay: Where appropriate, contribute genuine, factual payment experiences to support greater transparency.

You can explore the campaign in our article Clear From the Start.

10. A Practical New Customer Checking Process

A useful process should be straightforward enough for a busy business owner to follow consistently.

Here is an illustrative workflow that can be adapted to your organisation.

Stage One: Initial Enquiry

Owner: Sales or business owner.

Confirm the customer's legal identity, nature of the work, approximate contract value and proposed payment terms.

Record the information in your customer or project management system.

Stage Two: Due Diligence

Owner: Finance, credit control or the business owner.

Check relevant company records, available credit information and payment experiences.

Identify anything requiring clarification.

Record when the checks were completed and what information was reviewed.

Stage Three: Commercial Decision

Owner: Authorised manager.

Decide whether to proceed and what payment terms are appropriate.

If concerns exist, consider deposits, staged payments or an initial credit limit.

Document the reason for the decision.

Stage Four: Written Agreement

Owner: Sales or contract manager.

Confirm the scope of work, price, payment dates, invoice requirements and responsibilities.

Make sure both parties understand the arrangements before substantial costs are incurred.

Stage Five: Ongoing Monitoring

Owner: Finance or credit control.

Track invoice dates, payment performance, disputes and changes in customer circumstances.

Review material credit exposure periodically, particularly when increasing credit limits or accepting substantially larger projects.

Stage Six: Relationship Review

Owner: Business owner or account manager.

After the work is completed and the payment position is known, review the relationship.

Did the customer meet the agreed terms?

Were queries handled professionally?

Would you offer the same terms again?

This turns each commercial experience into information that can improve future decisions.

11. When Should You Check an Existing Customer Again?

Customer due diligence should not necessarily stop after the first transaction.

A company can change considerably over time.

Its financial position may strengthen or weaken.

Its management may change.

Its order volumes may increase.

Its payment processes may become more efficient or more difficult.

Consider reviewing an existing customer when:

They request a substantially higher credit limit.

You are about to accept a much larger project.

Their payment behaviour changes noticeably.

Significant new financial information becomes available.

There are material changes in the business relationship.

The appropriate review frequency depends on the size and nature of your exposure.

A customer purchasing £200 occasionally does not necessarily require the same monitoring as one receiving £100,000 of annual trade credit.

The objective is proportionate risk management, not unnecessary administration.

12. What If the Customer Refuses to Provide Information?

Not every prospective customer will immediately understand why you are asking for certain details.

That does not automatically indicate a problem.

Some organisations have complicated procurement procedures.

Others may be unfamiliar with the checks smaller suppliers carry out.

Explain your approach calmly.

For example:

"We carry out standard customer checks before agreeing credit terms. It helps us understand the appropriate arrangements and keeps our onboarding process consistent for everyone."

This makes the purpose clear without implying that the customer has done anything wrong.

If information remains unavailable, consider whether you can proceed under terms that limit your exposure.

For instance, payment upfront may be appropriate where a credit arrangement cannot be assessed adequately.

A professional checking process should protect your interests while treating prospective customers fairly.

13. Why This Matters Even More for Growing Businesses

Growth can create an unexpected financial problem.

As sales increase, a business may need to purchase more stock, employ additional people and deliver larger projects.

Those costs often arise before customer payments arrive.

The result is that a growing company can require more working capital, even while reporting higher revenue.

If new customers are also given generous credit terms without adequate checks, the financial pressure can increase.

This is why customer selection should form part of a wider growth strategy.

Instead of asking only how much new business you can win, consider how much exposure you can manage.

A smaller portfolio of reliable customers may offer more predictable cash flow than a larger portfolio with persistent payment difficulties.

Of course, no business can eliminate uncertainty entirely.

But sensible checks and appropriate terms can help reduce avoidable exposure.

14. The Role of Will They Pay

Businesses have traditionally relied on credit information, personal relationships, references and their own experience when deciding who to trade with.

Each can contribute something useful.

Will They Pay adds another perspective by helping make B2B payment experiences more visible.

The intention is to give businesses greater insight into how other organisations have experienced commercial payment relationships.

That includes recognising businesses that pay reliably, as well as providing a way to share genuine concerns.

When combined with credit checks and clear contractual terms, this can support more informed decisions.

It is important to remember that reviews represent reported experiences, not guarantees of future behaviour. Credit reports also have limitations and should be interpreted in context.

The value lies in having more relevant information available before committing substantial resources.

15. Your New Customer Checklist

Before agreeing to provide goods or services on credit, ask yourself:

Have we confirmed the customer's correct legal identity?

Have we reviewed relevant company information?

Have we considered whether a business credit check is appropriate?

Have we looked for available payment experiences?

Do we understand the total financial exposure?

Can we manage the proposed payment terms?

Have we considered deposits or staged payments?

Are the scope, price and payment terms documented?

Do we know who approves invoices?

Is there a clear process for disputes?

Have we assigned responsibility for monitoring the account?

Do we know when the relationship should be reviewed?

You do not need a complicated system to get started.

You need a process that is proportionate, consistent and actually followed.

16. The Best Time to Ask Questions Is Before You Need the Answers

There is nothing wrong with being enthusiastic about new business.

A promising enquiry should feel exciting.

But enthusiasm and due diligence should work together.

Checking a prospective customer's information is not an accusation.

Agreeing payment terms is not a sign of distrust.

Asking how invoices are approved is not being difficult.

These are ordinary parts of establishing a professional commercial relationship.

The strongest businesses do not simply focus on winning contracts.

They consider how those contracts will affect their cash flow, resources and long-term stability.

And they recognise that reliable customers deserve appreciation just as much as unreliable payment experiences deserve careful scrutiny.

The question is not whether every new customer presents a risk.

Every commercial arrangement involves some uncertainty.

The question is whether you understand enough about that uncertainty to make a sensible decision.

Before you say yes to the work, make sure you understand the payment arrangement.

That is what it means to be clear from the start.
