A debtor management rhythm that collects cash

Collection starts before the invoice exists

Most late payment problems get created at the start of the relationship, not at the end. Terms that were never actually discussed, invoices missing a purchase order number, work delivered to a customer who was never going to pay on time, all of it guarantees slow cash later. The pre work matters: agree payment terms in writing before starting, confirm exactly what the customer's accounts process needs on an invoice, and for larger jobs consider a deposit, which quietly tests payment behaviour before you're heavily committed. For new commercial customers of any size, a quick check of trading references before extending credit terms is cheap insurance.

Then invoice immediately. An invoice sent the day the work finishes starts the clock at the earliest possible moment and lands while the value's still fresh in the customer's mind. Send it three weeks later and you've signalled you're in no hurry, so the customer matches your energy.

The weekly rhythm

Set a fixed time each week, Tuesday at 9am, say, and work the aged receivables report from oldest to newest. The report tells you exactly who owes what and for how long; the rhythm decides what happens at each stage. A workable sequence looks like this.

• A few days before due date: a short friendly reminder that the invoice is coming up, which catches lost invoices and approval bottlenecks before they turn into lateness.
• One day overdue: an automatic reminder email. Polite, factual, invoice attached again, payment details front and centre.
• Seven days overdue: a phone call, not another email. Ask if there's any problem with the invoice; most of the time it's a mundane blockage a two minute call clears up.
• Fourteen days overdue: a firmer written follow up confirming the call, restating the amount, proposing a specific payment date.
• Beyond that: a decision point. A payment plan, pausing further work, director contact, or a debt collection process, and which one's right depends on the customer and the amount involved.

The magic isn't in any single step. It's that every debtor learns your follow ups always arrive, on schedule, every single time. Customers triage their payables, and suppliers who reliably follow up get paid ahead of the ones who don't.

Use the automation, keep the judgement

Modern accounting software will send invoice reminders automatically on whatever schedule you set, and online payment options on the invoice itself remove friction at the exact moment a customer's willing to pay. Automate the routine steps without a second thought. Keep the phone calls and escalation decisions human, because tone and context matter once an account's genuinely overdue. Monthly statements to account customers add another gentle layer too, catching invoices that individual reminders missed.

Watch two numbers monthly: debtor days, roughly how long customers take to pay on average, and the percentage of your receivables sitting beyond 30 days overdue. Improving those two numbers is the whole point of the rhythm, and they respond within a couple of months of running it consistently.

Making the rhythm someone's actual job

A rhythm only works if someone owns it, and in a lot of small businesses it silently belongs to nobody at all. NextEra runs debtor follow up rhythms for clients as part of ongoing bookkeeping, with aged receivables and debtor days tracked in the monthly management report. Receivables quietly crept up on you? The Strategic Finance Review shows exactly what that pattern looks like, and what it's costing.
