Offering credit can help you win work, build stronger trading relationships and make it easier for customers to buy from you. But if you set credit limits too loosely, you also increase the risk of slow payment, cash flow pressure and bad debt. In practice, a credit limit is not just a finance setting in your system. It is a risky decision.
That matters in the UK because late payment is still a serious issue for businesses of all sizes. The UK Government said in 2025 that over 1.5 million businesses are affected by late payment, and in January 2026 it said late payment costs the UK economy almost £11 billion a year and closes 38 UK businesses every day.
If you are setting credit limits for new business customers, the goal is not to eliminate all risk. That is rarely realistic. The goal is to give enough credit to support sales while keeping your exposure at a level your business can comfortably manage. That means using a simple process, applying the same thinking consistently and reviewing decisions as trading develops.
This is also where Taurus Collections fits naturally into the wider credit control picture. The business offers debt recovery, outsourced credit control and UK and international credit checking, all of which reflect the same principle: the earlier you assess risk, the easier it is to protect cash flow and avoid overdue accounts becoming a bigger problem later.
Start with your own risk tolerance
Before you look at the customer, look at your own business.
A sensible credit limit for one company may be far too high for another. If you are a large business with strong cash reserves, you may be comfortable carrying a higher level of debtor exposure. If you are a smaller business where a single unpaid invoice of £8,000 would create real pressure, your limits need to be tighter.
Ask yourself:
- how much can you afford to have outstanding with one customer
- how long can you comfortably wait to be paid
- what level of bad debt would genuinely hurt your business
- how dependent are you on a small number of customers
Your answers matter because credit limits should reflect your ability to absorb risk, not just the customer’s appetite to buy.
Check who you are dealing with
Before you agree a credit limit, make sure you know who the customer is and how they trade.
At a basic level, you should confirm:
- the full legal name of the business
- company registration details where relevant
- trading address and billing address
- key contacts in accounts payable
- whether the person placing the order has authority
- whether there are any unusual group structures or linked entities
This step sounds simple, but it prevents a lot of avoidable problems. If you invoice the wrong entity or fail to verify who is actually responsible for payment, recovery becomes harder later.
Taurus Collections specifically positions its credit checking service around helping businesses assess risk before extending credit, both in the UK and internationally.
Use credit checks as part of the decision
A credit limit should never be based only on what the customer asks for.
You should use available data to sense-check the level of exposure you are being asked to accept. A credit check can help you review the company’s background and spot obvious warning signs before you start trading. Taurus Collections states that its credit checking service is designed to help businesses assess risk and make informed decisions before offering credit.
You do not need to overcomplicate this. The key question is practical: does the level of credit requested look sensible when compared with what you know about the business?
For example, if a brand-new customer wants £20,000 of credit straight away, but you have little trading history with them, it may be safer to start lower and increase the limit over time.
Base the first limit on expected monthly exposure
A common mistake is setting a limit based on optimism rather than likely exposure.
Instead, estimate:
- your average monthly invoicing value
- the agreed payment terms, such as 30 days
- whether orders are likely to be regular or irregular
- whether there is any risk of disputes, delays or staged approvals
If you expect to invoice around £3,000 a month on 30-day terms, a limit of £3,000 to £5,000 may be more sensible than £10,000. If you expect larger but less frequent projects, you may need a different structure, such as staged billing or deposits.
Try to set the initial limit at a level that covers normal trading, not best-case growth. You can always increase it later once payment behaviour is proven.
Consider the customer’s payment terms carefully
Credit limits and payment terms work together.
A customer on 14-day terms may justify a different limit from a customer on 45-day terms. The longer the terms, the longer your cash is tied up, and the more chance there is of delay.
This is especially relevant given the current policy direction in the UK. In July 2025, the government said upcoming legislation would introduce maximum payment terms of 60 days, reducing to 45 days, alongside stronger enforcement measures and a 30-day invoice verification period.
That does not mean every customer will pay on time, but it does show how central payment timing has become. When you set a credit limit, do not look only at the balance. Look at how long that balance may realistically stay outstanding.
Separate low-risk and high-risk customers
Not every new customer should be treated in exactly the same way.
You may want different starting rules for:
- established UK limited companies with strong trading history
- overseas customers
- new businesses with limited track record
- customers placing unusually large opening orders
- customers in sectors where disputes are more common
- customers asking for extended terms from day 1
A lower opening limit, shorter terms, part-payment upfront or a deposit can all make sense where the risk is higher. This is not about being difficult. It is about making sure the trading relationship starts on a basis that is manageable for both sides.
Build in room for review
Your first credit limit should not be permanent.
A practical approach is to review a new customer after:
- the first completed payment cycle
- 3 months of trading
- a certain invoice value threshold
- any missed or delayed payment
- a material increase in order volume
This helps you reward good payment behaviour without taking too much risk too early. A customer who consistently pays within terms may justify a higher limit. A customer who starts slowly drifting beyond agreed dates may need tighter controls, not more credit.
Taurus Collections’ outsourced credit control service highlights ongoing reporting, payment monitoring and follow-up as core parts of effective credit control. That matters because a credit limit is only useful if someone is actively watching how the account performs against it.
Use internal rules, not one-off judgement calls
One of the easiest ways to create inconsistent risk is to make every credit decision ad hoc.
You are usually better off having a simple internal framework, such as:
1. Define standard opening limits
For example, you might set:
- up to £2,500 for new low-risk customers
- up to £5,000 where checks are strong and order volume supports it
- anything above that requires management approval
The figures will depend on your business, but having ranges makes decisions more consistent.
2. Link limits to approvals
If sales teams can agree credit informally, your controls will quickly weaken. Make sure there is a clear approval process for new accounts and limit increases.
3. Flag exceptions
Any request for longer terms, unusually high early exposure or repeated temporary extensions should be recorded and reviewed.
4. Pause supply where needed
A credit limit only works if it has consequences. If a customer is over limit or already overdue, you may need to pause further supply until the account is brought back under control.
Keep sales and finance aligned
A lot of credit problems start because sales and finance are working to different priorities.
Sales understandably wants to win the order. Finance wants to protect cash flow. Neither side is wrong, but both need the same information. If your team agrees a large account without thinking through payment risk, the problem often appears later when invoices age and chasing starts.
The best approach is to make credit limits part of customer onboarding, not an afterthought once the first invoice is already overdue.
Final thoughts
A good credit limit is not about guessing what might feel acceptable. It is about using a simple, repeatable process to decide how much exposure your business can safely take on with a new customer.
Start with your own risk tolerance, check who you are dealing with, use credit information sensibly, match the limit to realistic trading levels and review it as payment behaviour becomes clear. In most cases, that is far more effective than giving a generous limit at the start and hoping it works out.
When you set limits properly, you do more than reduce bad debt risk. You make your cash flow more predictable, your credit control stronger and your customer relationships clearer from the very beginning.
