When the invoice is overdue but nobody follows up
You open the inbox: an invoice has been overdue for ten days, reminders were not sent and replies get lost among other emails. In many SMEs this leads to tedious follow‑up work: which customers need a friendly reminder, which require a firmer escalation, and which debtors should be offered installment plans?
A structured open‑items workflow that controls reminders by customer segments provides relief here. In an on‑prem Debentra instance you define segmented rules tied to industry type, revenue, payment terms or other criteria. The result: personalized texts, appropriate intervals and clear escalation stages — with full control through your approval processes.
Why segmentation instead of a one‑size‑fits‑all solution?
The same reminder text has very different effects on a major customer, a public client or a small reseller. Segmentation brings two clear benefits:
- Targeted communication: Tone, payment options and legal notes are tailored to the customer group and increase acceptance.
- Efficiency gains: Automated intervals and escalations reduce manual assignments and prioritization; your team can focus on exceptions.
Step by step: creating segmented rules in Debentra
The following guide describes a field‑proven process you can implement in your on‑prem Debentra instance. Note: automated reminders are prepared — approval remains with the user.
1. Define target groups & criteria
Start with a maximum of four to six segments to avoid complexity. Examples of sensible criteria:
- Industry (e.g. healthcare, retail, trades)
- Revenue bracket (e.g. <25,000 €, 25,000–250,000 €, >250,000 €)
- Standard payment term (e.g. Net 14, Net 30, Net 60)
- History (regular late payers vs. punctual payers)
2. Create segments in Debentra
In the configuration area for customer rules, create the segment definitions. Don’t forget to assign a clear name and the associated filter criteria so that later adjustments remain easy to trace.
3. Create reminder texts and templates
Develop a template for each segment with three elements:
- Greeting and tone (neutral, friendly, formal)
- Specific payment request including payment reference
- Optional payment offers (installments, discount, contact person)
Example: Key account (revenue >250.000 €) – formal tone, note about individual payment terms and contact person; small client – friendly tone, brief reminder plus link to installment options.
4. Define intervals and escalation levels
Set the timing triggers for each segment. A simple, proven structure:
- Day 1–7 after due date: internal flagging, no dispatch
- Day 8–14: first reminder (friendly)
- Day 15–30: second reminder (specific, possibly threat of escalation)
- from day 31: escalation (call, dunning stage, debt-collection notice only if agreed)
Be sure to allow longer intervals and personal coordination for sensitive segments (e.g. public clients or key accounts).
5. Set up approval and review workflow
Automation should not be confused with disempowerment. Set up an approval instance where prepared reminders land in a queue and are checked and approved by the responsible clerks. Useful options:
- Automatic notification to the clerk when reminders are ready for approval
- Email preview including placeholder validation
- Dry run for new templates (test send to internal address)
6. Test and iterate
Before you activate rules in production, run a test with a small group of customers. Check:
- Hit rate of segment filters (are the right customers captured?)
- Placeholders in templates (invoice number, due date, amount)
- Approval workflow and logging
Practical wording examples
Instead of abstract advice, here are three short text modules for reminder templates:
- Friendly (small client): "Hello Mr/Ms {{Name}}, our invoice {{Rechnungsnr.}} dated {{Datum}} for {{Betrag}} was due on {{Fälligkeit}}. Please let us know briefly if the payment will be delayed."
- Businesslike (standard customer): "Dear Sir or Madam, according to our records the invoice {{Rechnungsnr.}} dated {{Datum}} is still outstanding. We ask for settlement within 7 days or for feedback regarding an installment agreement."
- Formal (key account/public client): "Dear Sir or Madam, we would like to courteously remind you of the outstanding payment for invoice {{Rechnungsnr.}}. Please inform us of the planned payment date or contact your representative {{Ansprechpartner}}."
Best practices and pitfalls
What you should keep in mind to get the maximum benefit from segmented rules:
- Maintain the control mechanism: automated suggestions yes, automatic sending only after approval.
- Start small: a few segments, simple rules, then refine step by step.
- Document exceptions: record manual deviations so the rule base can learn.
- Regular review: adjust intervals and texts every 3–6 months based on observations.
- No legal promises: reminder texts should remain informative; initiate legal steps only after internal review.
