Debtor Management Software: Complete Guide for Small and Medium-sized Enterprises
Debtor Management Software: Complete Guide for SMEs (2025)
Debtor management software is a digital system that automates the follow-up of outstanding invoices — from first reminder to collection transfer — so you get paid faster without spending time on them yourself.
For Dutch SMEs, this is no longer a luxury. On average, companies receive 11.43% of their annual turnover as late payments (Intrum European Payment Report 2024). On a turnover of €500,000, that is €57,000 who structurally arrives too late, every month.
Good debtor management solves that. The right software does it automatically.
In this guide, we explain what debtor management software does, what features are essential, how to choose and why the approach — not just the tool — makes the difference.

1. What is debtor management software?
Debtor management software is an application that manages the entire process of invoice follow-up: from automatic payment reminders and customer communication to escalation, collection transfer and reporting.
It replaces manual processes — keeping spreadsheets, sending reminders manually, making phone calls, managing records — with automated workflows that run consistently and at the right time.
The result: invoices are averaged 30% faster payment, while finance professionals save up to 80% time on debtor management (Softwarewatcher.nl, 2025).
2. Why you need to automate debtor management
The manual issue
Most SME entrepreneurs do debtor management manually or semi-automatically. That means: reminders that are sent too late, an inconsistent tone, forgotten follow-ups and files that are not in order when a case escalates.
The result is predictable. nearly a quarter of SMEs miss out on at least €20,000 annually in irrecoverable invoices (Exact SME Barometer 2025). And 90% of SMEs regularly experience problems due to late payments.
What automation solves
Consistency — reminders are always sent at the right time, in the right tone, and via the right channel. Not when someone thinks about it, but automatically.
quickness — the sooner you intervene, the greater the chance of payment. Receivables older than 90 days are becoming significantly more difficult to collect. Automation ensures that day 1 is also day 1.
overview — you can see at a glance which invoices have been outstanding, how long it has been, which next step is planned and what the total exposure is. No spreadsheets, no surprises.
Scalability — whether you have 10 or 1,000 outstanding invoices, the system works equally well. Manual management doesn't scale.
Dates — good debtor management software gives you insight into payment behavior per customer, segment and period. This data makes better credit decisions possible.
3. Which features are essential?
Not all debtor management software is the same. Here are the features that make the difference:
Must-haves
Automatic payment reminders
Personalized reminders at fixed times after the due date — with a variable tone (friendly → formal → summative) depending on the situation.
Customer profiles and segmentation
Not every customer deserves the same approach. You treat a regular customer with a temporary payment problem differently than a new customer who pays structurally late. Software that segments works more effectively.
Escalation logic
Clear rules for when a case escalates: from reminder to formal summons to collection transfers. Transparent, repeatable, not dependent on human judgment in the hustle and bustle of the day.
Reporting and DSO Tracking
Insight into your Days Sales Outstanding (DSO) — how long it takes on average for an invoice to be paid. Target value for SMEs: under 45 days If you don't know your DSO, you can't improve it either.
Integrations
Connection with your accounting package (Exact, Twinfield, Snelstart), CRM and bank portal. Without integration, debtor management software works in a silo — and you create duplicate work.
Payment links and ease of payment
Invoices payable instantly via iDeal, direct debit or other payment methods. The easier payment is, the faster customers pay.
Nice to haves
- Payment arrangement functionality (offering and monitoring instalments)
- Multichannel communication (email, SMS, mail)
- Credit scores and risk analysis per customer
- Statutory WIK cost calculator
- API for custom integrations
4. Types of debtor management software
There are three categories, each with a different application:
Type 1 — Integrated Accounting Modules
Think about Exactly, AFAS, Twinfield. Here, debtor management is a module within a larger accounting or ERP package. The advantage: everything in one system. Disadvantage: debtor functionality is rarely as advanced as with specialized software.
Suitable for: companies that are primarily looking for accounting and want to arrange debtor management as an afterthought.
Type 2 — Specialized debtor software
Think about Payt, POM, Onguard. Purely focused on invoice follow-up and cash flow. Advanced automation, segmentation, and reporting. Connects to accounting packages via API.
Suitable for: companies with a substantial debt portfolio where cash flow is a strategic priority.
Type 3 — Fully outsourced debtor management
Think about NIKKI Business. No software that you manage yourself — a partner who takes over the entire process. From the first reminder to collection transfer, with data, reporting and an approach that is tailored to your customer relationships.
Suitable for: companies that do not want to invest in software management, or where the approach (social debt collection, customer relationship retention) is at least as important as automation.
5. How do you choose the right software?
The right debtor management software fits the size of your debtor portfolio, integrates with your existing systems and supports the approach that suits your customer relationships.
Step 1 — Map out your situation
- On average, how many outstanding invoices do you have per month?
- What is your current DSO?
- How much time does your team spend managing accounts receivable now?
- Which existing systems need to be linked?
Step 2 - Determine what you need primarily
The right choice depends on where you are now. Do you have a small business with few invoices per month? Then an integrated accounting module is sufficient. You don't need a separate tool — the debtor functionality in your existing accounting package is sufficient.
Is your debtor portfolio growing and do you notice that manual management no longer works? Then specialized software is the next step. Tools like Payt or POM are specifically built for this — with advanced automation and reporting that an accounting module does not offer.
Is cash flow a critical factor in your company and do you want to keep customer relationships intact? Then fully outsourcing is the smartest choice. NIKKI Business takes over the entire process - from the first reminder to collection transfer - with an approach that is tailored to your customers and certified through the Social Debt Collection Agreement Framework.
Do you have a large portfolio and your own credit management team? Then you need enterprise software such as Onguard or AFAS — systems built for complex organizations with internal specialists who manage the platform themselves.
Step 3 — Test against these criteria
✅ Does automation really work without manual intervention?
✅ Can you adjust the tone and timing of communication by customer segment?
✅ Is the integration with your accounting package native or via an intermediate layer?
✅ Do you get real-time insight into DSO and outstanding portfolio?
✅ Does the system support payment arrangements?
✅ Is there support if something goes wrong?
6. Costs: what to expect?
The costs for debtor management software vary greatly by type of solution.
An integrated accounting module such as Exact or Twinfield costs between €25 and €100 per month. You get basic functionality that is directly built into your existing accounting environment. Specialized software such as Payt or POM costs between €50 and €200 per month. That's why you get advanced automation and comprehensive reporting — specifically built for debtor management.
Full outsourcing through NIKKI Business does not have a fixed monthly rate — the costs depend on the size of your portfolio. What you get in return: completely unburdened debtor management in accordance with the Social Debt Collection Agreement Framework.
Do you need custom connections via an API? Then count on a one-off investment of €5,000 to €20,000, depending on the complexity.
But never just compare the subscription rate. Always calculate the Total Cost of Ownership: how much internal time do you save, how much faster money comes in and how much escalation costs do you avoid? These three factors determine whether a solution is cheap or expensive — not just the monthly amount.
A concrete example: a company with an annual turnover of €500,000 that reduces its DSO from 50 to 30 days wins structurally ~€27,000 in extra liquidity — without generating an extra euro of turnover.
7. Software vs. full outsourcing: what's right for you?
This is the most frequently asked question. The honest answer: It depends on three factors.
Opt for software such as:
- You have an internal team that manages the system
- You want full control over communication and processes
- You're primarily looking for automation, not a strategic partner
Opt for outsourcing if:
- Debt management is not your core business and you want to fully delegate it
- Retaining customer relationships is at least as important as fast payment
- You work with vulnerable customer segments where the approach counts
- You want to benefit from social debt collection as a norm — but doesn't want to implement it yourself
NIKKI Business is not software that you purchase. It is a partner that takes over your debtor management — with an approach that is certified through the Social Debt Collection Agreement Framework, fully transparent and tailored to your customer relationships.

FAQs
What is the difference between debtor management software and a collection agency?
Debtor management software automates the process you carry out. A collection agency takes over the process entirely. At NIKKI Business, we combine both: automated processes and human guidance, fully outsourced.
Which debtor management software is best for SMEs?
That depends on your situation. Payt scores high for pure automation (Trustpilot 4.6/5, market leader in the Benelux). For completely unburdened social debt management, NIKKI Business is the only certified provider through the Social Debt Collection Agreement Framework.
Can debtor management software connect to Exact?
Yes. Most specialized tools offer native links to Exact Online, Twinfield, Snelstart and other common packages. Always check that the link works bidirectionally — changes in both systems must be synchronized.
How long does it take to implement debtor management software?
For cloud-based tools: 1 to 4 weeks depending on the complexity of the connection. Custom integrations can take 3 to 6 months.
What is a healthy DSO for my company?
The average DSO for Dutch SMEs is 31.7 days — but this has increased by 8.3% over the past year. A DSO under 45 days is considered healthy. Over 60 days, structural action is needed.
Is debtor management software GDPR-proof?
Good software stores customer data in accordance with the AVG/GDPR. Always check that the provider processes within the EU, offers a processing agreement and complies with the GDPR.
How does debtor management software specifically improve my cash flow?
By sending reminders faster and more consistently, customers pay earlier, on average. With the right software, an invoice is paid an average of 30% faster. On an outstanding portfolio of €100,000, 30% faster payment is immediate liquidity gain — without additional turnover.
