Setting payment terms that get you paid faster

Waiting for clients to pay can be one of the most frustrating parts of running a small business in the UK. Healthy sales figures mean little if the cash isn't actually in your bank account. The problem often starts long before an invoice becomes overdue. It starts with the payment terms you set—or fail to set—at the very beginning of a client relationship. This guide explores how moving beyond the default "30-day" terms and strategically using shorter terms, deposits, and milestone billing can fundamentally change your cash flow and get you paid faster.

Why Standard "Net 30" Isn't Always Your Best Friend

For decades, "Net 30" has been the default payment term for UK businesses. It means the client has 30 calendar days from the date of the invoice to pay. It sounds reasonable, professional, and is widely understood. So what's the problem?

For a small business, freelancer, or contractor, 30 days is a long time to wait for money you've already earned. You deliver the work on day one, issue the invoice, and then your business effectively provides a 30-day, interest-free loan to your client.

The reality is often worse. A "Net 30" invoice is rarely paid on day 30. It might get processed by the client's accounts department on day 30, meaning the payment run isn't for another week. Or it gets "lost," and you only find out when you chase it on day 31, resetting the clock. In practice, "Net 30" can easily become "Net 45" or "Net 60," creating a serious cash flow gap. While you're waiting, you still have to pay your own staff, suppliers, and overheads.

This is especially damaging for businesses that have significant upfront costs, such as creative agencies buying stock imagery, builders buying materials, or consultants paying for specialist software. Extending credit to large, slow-paying clients can put your entire operation at risk.

The Power of Shorter Payment Terms: 7 and 14 Days

One of the simplest ways to shorten your payment cycle is to shorten your payment terms. Moving from 30 days to 14 or even 7 days can have a dramatic impact.

Many small business owners are hesitant to do this. They worry it will seem demanding or scare off potential clients. This fear is usually unfounded.

• It sets a professional precedent: Requesting prompt payment isn't rude; it's a sign of a well-organised business with clear procedures. It communicates that you value your work and expect to be paid for it in a timely manner.
• It aligns with modern business pace: In a world of instant transfers and digital payments, waiting 30 days feels increasingly archaic. For smaller projects and new clients, a 7 or 14-day turnaround is perfectly reasonable.
• It capitalises on urgency: When a client receives an invoice with a 7-day due date, it creates a sense of immediacy. An invoice due in 30 days is easy to file away and forget about. An invoice due next week gets actioned.

How to Implement Shorter Terms

The key is to be upfront. It’s much easier to establish shorter terms with a new client than to change them for an existing one.

1. State it in your proposal: Your payment terms should be clearly listed alongside your pricing in your initial quote or proposal. A simple line like "Payment terms: 14 days from date of invoice" is all you need.
2. Reinforce it in your contract: Your formal terms of service or client agreement should reiterate the payment schedule.
3. Make it prominent on the invoice: The due date should be one of the most visible elements on your invoice. Don't make your client hunt for it.

For existing clients on Net 30, you can introduce a change by giving them notice. You might say, "For all new projects starting from [Date], we will be moving to 14-day payment terms to help us manage our cash flow and continue providing a great service." Most reasonable clients will understand.

Beyond Net Terms: Deposits, Milestones, and Retainers

For any project that isn't a simple one-off task, relying on a single invoice at the end is a high-risk strategy. You are performing 100% of the work before seeing a single penny. A much safer and cash-flow-friendly approach is to break up the payments.

Deposits (Upfront Payments)

Asking for a deposit is standard practice in many industries and should be in yours, too. A deposit is a portion of the total project fee paid upfront before any significant work begins.

• How much? A common starting point is 50%. For larger or longer projects, 25-40% might be more appropriate. The goal is to cover your initial costs and time investment.
• The benefits are huge:
  • Cash Flow: It immediately provides you with working capital.
  • Client Commitment: A client who has paid a deposit is financially invested in the project. They are more likely to provide timely feedback and be engaged in the process. It filters out time-wasters.
  • Risk Reduction: If the client disappears or cancels the project halfway through, you haven't lost everything. Your deposit should cover the work you've already done.

Frame the deposit not as a sign of distrust, but as a standard procedural step: "A 50% deposit is required to schedule the work and secure your project slot." Your terms and conditions should clearly state whether the deposit is refundable and under what circumstances.

Milestone or Staged Payments

For any project lasting more than a month, milestone payments are essential. This means breaking the project into distinct phases and invoicing as each phase is completed.

This approach ties payment directly to progress, which is fair for both you and the client. They can see what they are paying for, and you are compensated as you deliver value.

Example Milestone Structure for a £10,000 Website Project:

Stage	Deliverable	Payment
1. Project Start	Kick-off meeting & project scheduling	£3,000 (30% Deposit)
2. Design Approval	Wireframes & visual designs signed off	£4,000 (40% Milestone)
3. Project Completion	Website live & handover	£3,000 (30% Final Balance)

This structure ensures you are never more than 30-40% "out of pocket" on the project's value. It transforms your cash flow from a single lump sum at the very end to a more predictable stream of income throughout the project lifecycle.

Retainers

For ongoing services like marketing, IT support, or business coaching, a monthly retainer is the gold standard. The client pays a fixed fee each month for a specified amount of your time or a set of deliverables. This payment is typically due in advance, for example on the 1st of each month for the work to be done in that month. This completely eliminates chasing invoices for completed work and provides the ultimate predictable revenue.

The Legal Stick: Using Late Payment Legislation to Your Advantage

Even with the best terms, some clients will still pay late. Fortunately, UK law provides a powerful tool for small businesses: The Late Payment of Commercial Debts (Interest) Act 1998.

This legislation allows you to charge interest and a fixed compensation fee on overdue invoices for business-to-business transactions. This applies automatically, even if you haven't mentioned it in your terms.

There are two parts to the charge:

1. Statutory Interest: This is calculated at 8% plus the Bank of England's base rate. For example, if the base rate is 5.25%, you can charge 13.25% interest per annum on the overdue amount. The base rate changes, so you should always check the current rate on the Bank of England website when calculating.
2. Fixed Sum Compensation: You can also add a one-off compensation charge. The amount depends on the size of the debt.

Debt Size	Compensation Amount
Up to £999.99	£40
£1,000 to £9,999.99	£70
£10,000 or more	£100

You don't have to charge this, but simply having the right to do so is powerful leverage. Mentioning it on your invoices and in your terms demonstrates that you are serious about timely payment.

A simple sentence on your invoice is enough:

Payment is due within 14 days. We reserve the right to claim statutory interest and compensation for late payment under the Late Payment of Commercial Debts (Interest) Act 1998.

Often, the mere mention of this is enough to move your invoice to the top of the pile.

What if They Still Pay Late? The Art of Consistent Chasing

Setting clear terms is the foundation, but consistent follow-up is what ensures they are met. A disorganised chasing process, where you only remember to chase an invoice when your bank balance is low, sends a signal that your due dates aren't firm.

A professional chasing process is systematic:

• A polite reminder a few days before the due date.
• A follow-up on the due date if payment hasn't been received.
• A slightly firmer email 7 days after the due date.
• A final notice 14-21 days overdue, mentioning the potential for late payment charges.

Manually tracking this for every client is tedious and time-consuming. It's easy to let things slip, especially when you're busy with actual client work. This is where automation tools can be a game-changer. By setting up a sequence of reminders that are sent automatically, you can ensure every late invoice is chased consistently without you having to manually track and send each email. Products like InvoiceReminder connect to your accounting software and handle this entire process for you, formalising your credit control without the manual effort.

Summary: A Table of Payment Term Strategies

Choosing the right payment strategy depends on the nature of your work and your relationship with the client. Here is a summary of the options:

Term Type	Best For	Pro	Con
Net 30	Large corporate clients who have rigid payment cycles and with whom you have a long-standing relationship.	Widely understood and accepted as a default.	Creates a long cash flow gap; often paid later than 30 days.
Net 7 / Net 14	Smaller projects, new clients, and productised services.	Significantly improves cash flow; creates urgency.	May require explanation for clients used to Net 30.
Deposit + Final	Most projects of any significant size (e.g., brand design, copywriting, small building works).	Improves cash flow, ensures client commitment, reduces risk.	Requires issuing and tracking two invoices instead of one.
Milestone Payments	Long-term projects (e.g., software development, construction, extended consulting).	Creates predictable revenue throughout the project; closely ties payment to progress.	Requires careful project planning to define clear milestones.
Retainer	Ongoing, recurring services (e.g., SEO, social media management, IT support).	The best for predictable revenue; payment is often made in advance.	Only suitable for ongoing service-based relationships.

Ultimately, taking control of your payment terms means taking control of your business's financial health. By moving away from a passive "Net 30" default and proactively structuring terms that work for you, you can spend less time worrying about money and more time doing the work you love.

Frequently asked questions

Can I change my payment terms for an existing client?

Yes, but it requires clear communication. You should give your client advance notice, explaining why you are making the change (e.g., to standardise processes or improve cash flow). It's best to apply the new terms to new projects or a future date, rather than retroactively to work already agreed upon.

What's the difference between "Net 30" and "30 days EOM"?

"Net 30" means payment is due 30 calendar days from the date printed on the invoice. "30 days EOM" (End of Month) means payment is due 30 days after the end of the month in which the invoice was issued. EOM terms can significantly delay payment. For an invoice issued on the 2nd of June, Net 30 would make it due on the 2nd of July. In contrast, 30 days EOM would make it due on the 30th of July, almost 60 days after the invoice date.

Do I have to go to court to claim late payment interest?

No, you don't need to go to court simply to claim it. You have the right to re-issue the invoice with the statutory interest and compensation added. However, if the client refuses to pay this additional amount, enforcing it would require further action, potentially including the small claims court. Often, the formal threat of these charges is enough to prompt payment of the original invoice amount.

Are shorter payment terms like 7 or 14 days unprofessional?

Not at all. In today's fast-paced business environment, shorter payment terms are becoming increasingly common and are seen as a sign of an efficient, well-run business. It's about setting clear expectations from the start. As long as the terms are communicated clearly and upfront in your proposal and contract, it is perfectly professional.

If I take a deposit, do I issue one invoice or two?

Typically, you would issue two separate invoices. The first invoice is for the deposit amount and should be marked as due immediately or upon receipt to secure the booking. The second invoice is for the final balance and should be issued upon completion of the project, with a due date according to your standard terms (e.g., 14 days). This keeps your accounting clean and clear.
