The 7-Step Plan to Reduce Debtor Days

Reducing debtor days is about tightening processes, not chasing customers harder. This article sets out a clear seven-step plan businesses can follow to improve payment times, from setting expectations early to following up consistently. It explains how small, structured changes to credit control can significantly improve cash flow without damaging customer relationships.

The 7-Step Plan to Reduce Debtor Days

Late payments can be really frustrating, slowing down your business and making it tricky to manage the day-to-day bills. When customers delay payment, your debtor days go up. This refers to the average time it takes you to get paid after sending an invoice.

Too many debtor days stop you from growing your working capital. Instead of focusing on getting bigger, your team can get tied up spending valuable time chasing up bills.

Let’s look at a 7-step plan for simple, friendly, and effective credit control services. Below, you’ll learn how to properly reduce debtor days, steady your finances, and let your team focus on bringing in revenue, not just chasing money.

What Are Debtor Days?

Think of this as your finance score. It shows how long customers take to pay you compared to the terms you agreed on. If you ask for 30 days, but they usually take 45, that 15-day delay shows your cash flow is getting held up for no good reason. Our aim is to close that gap by being consistent and professional.

1. Set Clear Terms & Invoice Fast

The payment clock should start the second the job is done. Clear terms stop payments from going overdue, and acting fast gets the process moving quickly.

Set Perfectly Clear Terms: Your contracts need to be clear. Don’t just say “Net 30” and give an estimated date. Instead, write: “Payment is due 30 days from the invoice date.”
Document Agreement: Always have something in writing, like a signed contract or a formal email, that confirms the customer agrees to your payment schedule.
Invoice Immediately: Have a strict rule that invoices must be created and sent within one business day of finishing the job or hitting a key milestone.
Perfect Invoices: Make sure every invoice is complete, including the Purchase Order number, a detailed list of the work, and the name of the person who ordered the job. This detail stops the bill from getting lost in their accounts department.

2. Check Customer Credit

Not every sale is worth risking your cash flow. Taking on a customer who isn’t financially sound can mean high debtor days before you’ve even sent the first bill.

Run Credit Reports: If you use a tool, check new customers to see how financially stable they are. Watch out for any clear signs that point to a potential risk.
Monitor for Alerts: If you get an alert during the relationship that a customer’s risk is changing, let your client know straight away so you can advise on the best next steps, such as changing payment terms.

3. Send Monthly Statements

A good way to manage customer relationships and keep things clear is by sending a monthly overview of what they owe.

Send Monthly Statements: At the start of each month, send a clean, clear statement showing all open balances.
Include All Details: The statement should list every unpaid invoice. Always offer to send the original invoice documents again if the customer needs them. This is a non-aggressive way to keep all outstanding balances top-of-mind.

4. Send Pre-Due Reminders

The best way to stop late payments is to deal with them before they’re late. Being this proactive shows you’re organised and helps sort out any last-minute admin problems.

Review Upcoming Payments: Keep a weekly list of invoices due within the next 7 days.
Send Friendly Reminders: Based on the customer’s history and the invoice value, send a simple, low-pressure reminder before the due date. This can be an email confirming that everything is on track for payment.

5. Gentle Overdue Nudges

Once an invoice is overdue, the first step is always a gentle, consistent reminder to get them talking.

Initial Reminder Sequence: Send up to three friendly reminders over the course of a week (every two to three days).
Goal: The main goal is to get a reply and agree upon a definite payment date. Keep up this friendly contact until a date is confirmed.

6. Fix Issues & Find The Right Person

If Stage 1 doesn’t get a reply, it’s usually because of an admin hold-up, not that they don’t want to pay. Your next step should be collaborative, making sure the right person has the invoice and there are no questions about it.

Check Company Status: Confirm the company is still active (e.g., checking Companies House).
The Follow-Up Call: It’s much harder to ignore a phone call. A credit controller keeps the tone friendly, polite, and helpful when you:

Confirm the correct contact person for payments (and update your software).
Check for any questions about the invoice or Purchase Order that need resolving.
Ask for a confirmed payment date.

The Firmer Attempt: If contact is difficult, send a slightly firmer overdue reminder, try one last phone call, and leave a voicemail followed by an email to document the attempt.

7. Importance of Outsourced Credit Control

If all consistent, friendly attempts fail, you need to step up to formal action to protect your cash flow. This is where professional credit control services become essential, as this final step must be managed professionally and with your client’s full approval.

When a debt remains overdue, outsourcing allows a dedicated team to present a list of carefully managed escalation options to the client, such as:

Final Escalation Email
Payment Plan Offer
Service Restriction Warning
Letter Before Action

This approach provides Professional Objectivity. It’s a third-party credit controller that follows the agreed-upon plan perfectly, staying firm but fair. It saves staff time, allowing your team to focus on core business growth.
