The verdict in three sentences
An automated collections workflow triggers scheduled multi-channel reminders (email, SMS, letter) the moment a due date is missed, connected to your accounting, with escalation up to a formal demand letter. Budget 8,000 to 20,000 EUR and 3 to 6 weeks to deploy. Typical gain: a DSO cut by 15 to 25 days, freed cash and sharply reduced admin time.
What automating collections costs in 2026
Budget depends on the number of scenarios, channels and accounting integration. 2026 order of magnitude:
| Scope | Setup (EUR) | Timeline | Subscription/month |
|---|---|---|---|
| Scheduled email reminders | 8,000 - 10,000 | 3 weeks | 50 - 120 EUR |
| + SMS + accounting connector | 10,000 - 14,000 | 4 weeks | 120 - 250 EUR |
| + Per-segment scenarios | 14,000 - 17,000 | 5 weeks | 200 - 350 EUR |
| + Letters and automated demand | 17,000 - 20,000 | 6 weeks | 300 - 450 EUR |
| Annual maintenance | 15 - 18 % of project | - | - |
Automated postal sends (registered demand letters) cost roughly 5 to 8 EUR per letter via a digital mailing service, triggered only at final escalation.
The impact on cash flow
The main lever is DSO: every day gained frees cash tied up in receivables.
| Metric | Before | After automation |
|---|---|---|
| Average DSO | 62 days | 42 days |
| Reminders sent on time | 40 % | 100 % |
| Accounting time/week on dunning | 8 h | 1.5 h |
| Receivables > 90 days | 12 % | 5 % |
| Delay before 1st reminder | 8 - 15 days | Day D+1 |
| Disputes handled with history | Partial | Complete |
On an 800,000 EUR receivables book, cutting DSO by 20 days permanently frees about 44,000 EUR of cash (calc: annual revenue / 365 x days gained).

Mini case study
Marc, manager of a construction services SME in Dublin (28 staff, 5.4 M EUR revenue), suffered a 62-day DSO and 8 h/week of irregular manual dunning. After automation at 14,000 EUR (multi-channel reminders + accounting connector), DSO drops to 42 days. The 20-day gain on 5.4 M EUR revenue frees about 296,000 EUR of cash previously drawn on overdraft; at a 6 %/year financing cost, that is ~17,800 EUR/year in avoided interest, plus 6.5 h/week returned to accounting. The project pays back in under 10 months on interest savings alone.
FAQ
Aren't automated reminders too aggressive? No: scenarios are segmented (good payer, occasional delay, dispute) with calibrated messages. Escalation to a demand letter happens only as a last resort and under validation.
Does it integrate with my accounting software? Yes: most solutions (Sage, Xero, QuickBooks, Cegid, Pennylane) expose an API or usable export to sync invoices and payments.
What if a client disputes an invoice? The workflow pauses the reminder and opens a dispute case with the full history, avoiding untimely reminders and easing resolution.
Does an automated demand letter hold legal value? Yes, sent as registered electronic or postal mail with proof of dispatch, it is a valid step before formal recovery proceedings.
How long to a return on investment? From the first quarter: lower DSO frees cash and cuts interest, often for an ROI in 8 to 12 months.
