Auto Top-Up Moves Into SAFE CRM

The cheapest debt to collect is the debt that never exists.

Auto top-up has been in the SAFE Billing Platform for years. Each day it checks pre-pay accounts against their trigger and collects the top-up by card or Direct Debit. It has always worked well and it has always been slightly buried.

With the CRM launch, it moves. Auto top-up now sits in SAFE CRM alongside credit control, with better reporting behind it.

Key Takeaways

  • Auto top-up moves from the billing platform into SAFE CRM, next to credit control
  • Usage paid for in advance never becomes a debt on your aged report
  • The reporting is the real change: recent top-ups, accounts near their trigger and broken setups in one place
  • Pre-pay suits new customers, higher-risk accounts and anyone you would rather not extend credit to
  • It sits alongside credit control rather than replacing it, because not every customer suits pre-pay
  • Launching with SAFE CRM, with early access open now

Key terms in this article

What does pre-pay mean?

Pre-pay means the customer puts money on their account before using the service, rather than being invoiced afterwards. Their balance falls as they use calls or data. UK telecoms resellers often use it for new customers or accounts they would rather not extend credit to.

What is auto top-up?

Auto top-up is an automatic collection that runs when a pre-pay balance drops below a level you set. SAFE checks daily and collects the agreed amount from the customer’s saved payment method, by card or Direct Debit, so the service keeps running without anyone raising an invoice. A card clears quickly; a Direct Debit settles over the following few days. Where there is no usable payment method, it records the payment as expected and flags the account rather than pretending the money arrived.

What is aged debt?

Aged debt is money your customers owe you, grouped by how long it has been outstanding. The older the balance, the harder it is to collect. It is the report most credit control work runs from.

Why This Matters More Than It Sounds

Most of what we write about getting paid is about chasing. Reminder sequences, escalation, aged debt buckets, when to put an account on hold. All of it is work you do after the money is already late.

Pre-pay removes that work rather than automating it. A customer on auto top-up funds the account ahead of use, so there is no invoice to chase and no bucket for it to age into. They never enter the credit control process at all. What can still need attention is a failed collection, an account with no usable payment method, or an ordinary invoice sitting alongside the pre-pay balance.

That is a different kind of saving from a faster dunning run. It does not make chasing more efficient. It reduces how many customers you have to chase at all.

Who Pre-Pay Suits

Not everyone, and that is the point. Pre-pay works well for:

  • New customers with no payment history. You do not yet know how they pay. Pre-pay means you do not need to find out the expensive way.
  • Accounts that have been trouble. A customer who has been through your full chasing sequence twice is a candidate for moving to pre-pay at renewal rather than being lost entirely.
  • Small accounts where credit checking is not worth it. Running a proper credit assessment on a £30 a month account costs more than the exposure.
  • Customers who prefer it. Some businesses genuinely like a fixed, predictable spend with no invoice to process.

It suits some customers badly. Larger business customers with purchase order processes will not accept it, and should not be asked to. Pre-pay sits alongside credit control, not in place of it.

From our experience: the resellers who use pre-pay well tend to treat it as a destination rather than a default. New accounts start on pre-pay and graduate to invoiced terms once they have a payment history worth trusting. Difficult accounts move the other way at renewal. Used like that it becomes a lever rather than a product tier, and it takes real weight off the aged debt report.

What Actually Changes

Auto top-up itself works as it always has. The customer has a balance, a trigger level and a top-up amount. The daily run checks eligibility, and waits out a cooldown so an account cannot top up repeatedly in a few hours. It collects by card or Direct Debit, and raises a follow-up on the accounts where it cannot.

Three things are different now that it lives in the CRM.

The reporting is proper reporting. Recent top-ups, accounts within 20% of their trigger, and accounts with a missing setting or no way to pay, all in one place rather than assembled from the billing side when you need it. Each top-up records the amount, the outcome and the method used, so you can see which customers are topping up more often than expected. That is usually the first sign somebody has outgrown their arrangement.

Failures are visible where somebody will act on them. A failed top-up is not aged debt, but it is the thing that becomes aged debt if nobody notices. It lands on the same worklist as everything else needing a person, with the reason attached.

It sits next to credit control. Moving a customer between pre-pay and invoiced terms is a credit decision. Having both in the same workspace means that decision gets made with the payment history in view rather than from memory.

How It Fits With Credit Control

The two work as a pair.

Credit control handles the customers you invoice: staged reminders, payment arrangements, holds and a daily worklist driven by live invoice data.

Auto top-up handles the customers you would rather not invoice at all.

Between them, the aim is a shorter aged debt report. We have written on the company site about the full credit control process, about how to read an aged debt report and about debtor days, the single number worth trending alongside it. For the chasing side specifically, our post on why statutory interest rarely works covers what actually recovers cash from customers you do invoice.

Availability

Auto top-up reporting launches with SAFE CRM. Existing configurations carry across and nothing needs setting up again. The issue report will show any account whose setup needs attention.

If you already use pre-pay, you will find it where credit control lives rather than where it used to be. If you have never used it and have a handful of accounts you would rather not carry the risk on, it is worth a conversation.
