The verdict in three sentences
Automating the quote-to-cash cycle (quote → invoice → dunning → collection) in Amsterdam costs between 8,000 and 22,000 EUR in 2026, accounting integration included. The main lever is a DSO reduction of 10 to 20 days, an immediate cash shock for an SME. ROI materializes in 5 to 9 months, driven by multichannel dunning and the end of missed invoicing.
What quote-to-cash automation covers
The scope runs from a signed quote to bank reconciliation. The more complete the chain, the more cash recovered.
| Module | Function | Price (EUR) | Cash impact |
|---|---|---|---|
| Quote generation | Auto quote from CRM | 2,000 – 4,000 | Shorter cycle |
| Invoicing | Invoice at signature/delivery | 2,500 – 5,000 | Issued 3 days earlier |
| Multichannel dunning | Sequenced email + SMS + WhatsApp | 2,500 – 6,000 | DSO −10 to −20 d |
| Bank reconciliation | Auto matching of collections | 3,000 – 7,000 | Real-time visibility |
The quantified DSO impact
DSO (Days Sales Outstanding) measures the average collection delay. Every day saved unlocks cash proportional to revenue.
| Annual revenue (EUR) | DSO before | DSO after | Cash unlocked (EUR) |
|---|---|---|---|
| 800,000 | 62 d | 47 d | ≈ 32,900 |
| 1,500,000 | 58 d | 42 d | ≈ 65,800 |
| 3,000,000 | 55 d | 38 d | ≈ 139,700 |
| 5,000,000 | 60 d | 45 d | ≈ 205,500 |
_Cash unlocked ≈ (revenue / 365) × DSO days saved — 2026 order of magnitude._

Mini case study
Julien, owner of a trading SME in Amsterdam, runs 1.5 M EUR revenue with a 58-day DSO and two manual dunning runs per month. He invests 15,000 EUR in quote-to-cash automation plus 140 EUR/month of tooling. DSO drops to 42 days: 65,800 EUR of cash unlocked once, and ~9 h/week returned to the accounting team (≈ 13,000 EUR/year). Full ROI in ≈ 7 months.
FAQ
What DSO gain can I target? A reduction of 10 to 20 days is realistic with automated sequenced dunning. On 1.5 M EUR revenue, each day is worth about 4,100 EUR in cash.
Does it integrate with my accounting software? Yes: Exact, Pennylane, Sage or QuickBooks expose APIs. Accounting integration is 2,000 to 5,000 EUR depending on the tool.
Is WhatsApp dunning effective in B2B? WhatsApp open rates exceed 90% versus 25-35% for email. An email + SMS + WhatsApp sequence sharply cuts late unpaid invoices.
What is annual maintenance? Budget 1,500 to 4,000 EUR/year for changes and monitoring of bank connectors, often billed as a monthly subscription.
What is the timeline? A full quote-to-invoice-dunning-reconciliation chain ships in 6 to 10 weeks, with a first module (dunning) live by week 3.
