The verdict in three sentences
An automated collection system connected to your billing costs 4,000 to 10,000 EUR in 2026 and cuts the admin time spent on chasing payments by three. It typically drops DSO from 58 to 42 days and reduces bad debt by 30% by pacing reminders with no gaps or delays. For an SME billing 2M EUR a year, the ROI lands in under 6 months, on recovered cash alone.
What collection automation costs in 2026
Price depends on the number of scenarios, channels (email, SMS, letter) and how deeply it connects to your billing tool. 2026 order of magnitude for the UK/European market:
| Scope | Indicative price | Lead time | Included |
|---|---|---|---|
| Simple email reminders | 4,000 - 5,500 EUR | 2-3 wks | 3 scenarios, billing connection |
| Email + SMS multi-level | 6,000 - 8,000 EUR | 3-5 wks | Segmented scenarios, D+7/D+15/D+30 |
| Full collection suite | 8,000 - 10,000 EUR | 5-7 wks | + letter, DSO dashboard, legal escalation |
| Auto formal notice option | + 1,500 - 2,500 EUR | +1 wk | Legal template, delivery tracking |
| Annual maintenance | 900 - 1,800 EUR/yr | — | Adjustments, support |
Add variable costs: SMS delivery (0.05-0.08 EUR each) and optionally an e-signature or registered-letter module.
The measurable cash impact
The real gain isn't the software cost, it's the cash freed up. Here is the typical before/after on a B2B SME:
| Metric | Before (manual) | After (automated) | Delta |
|---|---|---|---|
| Average DSO | 58 days | 42 days | -16 days |
| Bad debt > 60 days | 9.5% | 6.5% | -3 pts |
| Admin time/week | 9 h | 3 h | ÷3 |
| Invoices chased on time | 55% | 98% | +43 pts |
| Chase cost/invoice | 4.20 EUR | 1.10 EUR | -74% |
On 2M EUR of revenue, cutting 16 days of DSO frees roughly 88,000 EUR of working capital, durably.

Mini case study
Claire, finance director of a 40-person industrial SME in London, bills 2.4M EUR/year with a 60-day DSO. She invests 7,500 EUR in a three-tier email + SMS collection engine linked to her billing software. Within four months DSO drops to 44 days: 16 days × (2.4M / 365) ≈ 105,000 EUR of cash released. Her accounts assistant's time falls from 8 h to 2.5 h a week, saving ~9,500 EUR/year. Total first-year cost (7,500 + 1,400 SMS/maintenance) is recovered in under 5 months.
FAQ
How long to deploy a collection system? Expect 2 to 7 weeks depending on complexity. An email core connected to your billing goes live in 2-3 weeks; a multi-channel setup with legal escalation takes 5 to 7 weeks.
Will it integrate with my current billing software? Yes, via API or connector for most market tools (Xero, QuickBooks, Sage, Pennylane). If the tool has no API, an automated file import still works with 1-2 extra days of work.
Won't automatic reminders annoy customers? Not if scenarios are segmented: courteous tone for good payers, growing firmness past 30 days. Satisfaction usually rises, since reminders are regular and predictable rather than erratic.
What realistic ROI should I expect? For an SME billing 1-3M EUR, payback sits between 4 and 6 months, 80% driven by DSO reduction and 20% by admin time saved.
Can we add formal notices and legal escalation? Yes, as an option (1,500-2,500 EUR). The system automatically generates a compliant formal notice after a set number of reminders, with delivery-receipt tracking.
