The verdict in three sentences
Automating invoicing and collections costs a Dublin SME EUR 6,000 to EUR 20,000 depending on invoice volume and the number of reminder levels. The project fits the e-invoicing rollout spreading across the EU in 2026-2027, making it a structural investment. The most measurable impact is a DSO reduction of 10 to 20 days, an immediate cash-flow gain.
What invoicing + collections automation costs
Pricing depends on volume, the number of reminder scenarios and integration with your accounting tool or ERP. 2026 ballpark figures.
| Scope | Content | Price EUR | Timeline |
|---|---|---|---|
| Automated invoicing | Generation + send + archiving | 6,000 – 9,000 | 4–5 wks |
| Multi-level reminders | 3-4 email/SMS scenarios + tracking | 9,000 – 14,000 | 5–6 wks |
| Collections suite | Invoicing + reminders + DSO dashboard | 14,000 – 20,000 | 6–8 wks |
| E-invoicing compliance | Structured format + certified platform | +3,000 – 6,000 | +2–3 wks |
Maintenance is around EUR 250/month: scenario updates, compliance monitoring, reminder tuning.
The impact on DSO and cash flow
DSO (Days Sales Outstanding) measures average payment delay. Every day saved frees cash. Simulation across three SME profiles.
| SME profile | Annual revenue | DSO before | DSO after | Cash freed |
|---|---|---|---|---|
| B2B services | EUR 1.2M | 62 d | 46 d | ~ EUR 53,000 |
| Distribution | EUR 3M | 55 d | 40 d | ~ EUR 123,000 |
| Manufacturing | EUR 5M | 68 d | 52 d | ~ EUR 219,000 |
| Construction subcontracting | EUR 2M | 78 d | 60 d | ~ EUR 99,000 |
Cash freed = (DSO before − DSO after) × revenue / 365. These are not recurring savings but a one-off cash-flow gain that improves working capital and cuts financing costs.
Mini case study
Aoife, Finance Director of a 30-person digital services SME in Dublin (EUR 2M revenue), ran a 61-day DSO with irregular manual reminders. We deployed e-invoicing-ready automated invoicing and a 3-level reminder scenario (D+3, D+15, D+30) for EUR 13,500, EUR 250/month support.
Within four months DSO fell to 45 days. Cash freed is (61 − 45) × 2,000,000 / 365 ≈ EUR 87,700. At a 5 % short-term financing cost, that is about EUR 4,400/year in financing costs saved, plus the accountant's collections time cut threefold. The investment is paid back within the first year on the cash effect alone.

FAQ
Is e-invoicing mandatory?
EU rollout timelines run across 2026-2027 by company size. Automating now lets you comply without rushing and absorb the change smoothly.
How many reminder levels are needed?
Three to four cover most cases: courteous reminder, firm follow-up, formal notice, then escalation. Each level fires automatically based on invoice age.
What is a realistic DSO gain?
Between 10 and 20 days for an SME with previously manual, irregular reminders. The effect is strongest once reminders become systematic and tracked.
Do we need specific accounting software?
No. The automation connects to most accounting tools and ERPs via API. The structured format required by e-invoicing is handled by the certified platform.
What is the setup timeline?
Between 4 and 8 weeks depending on scope. Invoicing alone is faster than the full collections suite with a DSO dashboard.
