Custom collections software development
Appfront builds custom debt collection software that helps you track outstanding invoices, automate reminders and demand letters, and get paid faster. From automated reminder flows and SEPA Direct Debit with mandates to payment links, payment arrangements and escalation to a collection agency, the software fits your own invoicing process and steers on key metrics such as DSO and outstanding balance.
What is debt collection software?
Debt collection software automates the entire process from outstanding invoice to received payment. The software keeps track of which invoices are open and for how long, automatically sends reminders and demand letters according to your own policy, gives customers payment links and payment arrangements, and, where desired, carries out automatic collection via SEPA mandates. If a claim gets stuck, the software supports a controlled escalation to a collection agency or bailiff.
Off-the-shelf packages often force you into a fixed reminder schedule and a fixed way of working. Custom software works the other way round: the software follows your invoicing flow, customer segments and collections policy. You decide the reminder deadlines per customer segment, connect the software to your accounting and payment provider, and stay in control of how and when collections happen. This is especially valuable if you handle high invoice volumes, recurring subscriptions or a wide range of customer groups.
It is important to note that Appfront builds the software, but we do not collect invoices on your behalf and do not provide legal or financial advice. The decision to pursue collection and the legal steps remain with your own organisation. For the basics of SEPA Direct Debit, we follow the guidance of Betaalvereniging Nederland on European direct debit, mandates and refund rights, so that the software correctly supports the rules.
Outstanding invoices at a glance
A clear debtors dashboard with open items, ageing analysis and payment status per invoice. You see at a glance what is outstanding, for how long, and which customers need attention, without searching through scattered lists or emails.
Automated reminders
Reminder and demand letter flows that start automatically based on due date and customer segment. A friendly reminder, a formal demand and a final notice follow one another according to your own deadlines, each with the right tone and a direct payment link.
Collection and payment arranged
SEPA Direct Debit based on mandates, complemented by payment links and online payment for customers who prefer to transfer themselves. For those who cannot pay in one go, the software offers instalment payment arrangements, monitored automatically.
Our development process for debt collection software
We work to an approach that removes uncertainty early and moves step by step towards reliable software. From an initial analysis of your invoicing process, customer segments and collections policy through to go-live and ongoing management, every step is aimed at debtor management that your own team can understand and trust.
We map out your invoicing flow: which customer groups you bill, what your reminder policy looks like, whether SEPA direct debit is involved, and which accounting package and payment provider the software needs to connect to.
We design the data models, the reminder and escalation flows, and the SEPA and payment integrations, and align the dashboard and reporting with your key figures.
We build in short iterations with automated tests, logging and monitoring. You see working versions along the way and can adjust the collections policy and flows before anything goes live.
A controlled go-live with data validation and a safety net for the first collection runs, followed by ongoing management, monitoring and further development.
What custom debt collection software delivers in practice
Every debt collection software solution is tailored to your type of invoices, customer groups and adjacent systems. Below are the features we most often deliver for organisations looking to automate their accounts receivable management and debt collection.
Accounts receivable overview & ageing analysis
A central dashboard showing all outstanding items, sorted by age and amount. You can see which invoices have recently fallen due and which have been open for a long time, with filters per customer group, so your team can focus follow-up where it makes the most difference.
Reminder & demand letter workflows
Automated workflows that send a friendly reminder, a formal demand letter and a final notice based on due date and customer group. You set the timeframes, tone and channels yourself, with a direct payment link included in every message.
SEPA direct debit & mandate management
Management of SEPA mandates for both Core and B2B, including creating direct debit files for your bank. The software takes into account the different refund rights: no refund right for B2B, and a refund period for Core, so your collection runs are accurate.
Payment links & instalment plans
Online payment via a payment link in every reminder, connected to your payment provider. For customers who can't pay in one go, the software offers instalment arrangements that are monitored and collected automatically.
Dunning escalation
If a claim remains unpaid after all reminders, the software supports a controlled escalation process: the file is enriched and handed over to a debt collection agency or bailiff. You stay in control of which claims escalate and when, and the decision always rests with you.
Reporting: DSO & outstanding balance
Reporting on the key figures that matter: DSO (average days to payment), total outstanding balance, ageing breakdown and the results of your reminder workflows. Your finance team can see trends per customer group and adjust collection policy on a solid evidence base.
Who is debt collection software for?
Custom debt collection software works differently for each organisation. We often see a number of recurring situations, typically involving high invoice volumes or recurring payments, where automating reminders, demand letters and SEPA direct debit saves time and reduces arrears straight away.
SMEs with high invoice volumes
SMEs with high invoice volumes where manual chasing can no longer keep up. The software tracks every outstanding item, sends reminders automatically and connects to your accounting, for example via an Exact Online integration, so payment statuses update by themselves. If collections are part of a wider system, also look at a custom ERP system.
Subscription businesses
Organisations with recurring billing, such as SaaS products, gyms and service subscriptions. Recurring invoices are collected automatically via SEPA mandates, with payment links as a fallback. For online payments, we connect to your payment provider, for example with a Stripe integration.
Associations & membership fees
Associations and clubs that collect annual or seasonal membership fees from their members. Automatic direct debit from the membership register, with reminders for members who have not provided a mandate. This integrates seamlessly with membership management software, where membership and payments come together.
Healthcare providers
Healthcare providers and practices with many small claims and patient co-payments. The software bundles outstanding items per patient, sends considerate reminders, and offers payment links and instalment plans. Sensitive data is processed in line with GDPR, with attention to data minimisation and access control.

Security and privacy in direct debit software
Debt collection software always processes personal data, payment details and SEPA mandates. That is why Appfront builds to the OWASP Top 10. In practice this means encryption in transit and at rest, role-based access following least privilege, careful validation and logging, and secrets management for the integrations with your bank and payment provider.
We also configure the software to meet the requirements of the GDPR: data minimisation, a lawful basis for every processing activity, and clear retention periods for debtor and mandate data. We document the data flows so your record of processing activities is complete, and keep an audit log of direct debit runs and reminders as a traceable evidence trail.

Frequently asked questions about direct debit software
Answers to the questions we are asked most often about custom direct debit software.
Direct debit software is a system that automates your receivables management and the collection of outstanding invoices. It tracks which invoices remain open, sends reminders and dunning letters on time, offers customers payment links and payment arrangements, and can carry out automatic collection via SEPA mandates. With custom direct debit software, the software matches your own invoicing flow, customer groups and dunning policy precisely, rather than you having to adapt your process to a standard package.
SEPA Core (the standard European direct debit) can be used by both consumers and businesses, and according to the Dutch Payments Association, the payer has the right to have a debit reversed within eight weeks without giving a reason (known as a reversal). SEPA B2B (business-to-business European direct debit) applies exclusively to transactions between businesses and carries no reversal right; once processed, the debit is final. B2B always requires a new, specific mandate, and an existing Core mandate cannot be reused for this purpose. We build the software so that both variants are supported correctly.
No. Appfront is a software developer, not a debt collection agency. We do not collect invoices for you and we do not provide legal or financial advice. We build the software that allows your own team to manage receivables and collections efficiently: tracking outstanding items, automating reminders and formal demands, preparing SEPA direct debits, and supporting escalation to a debt collection agency or bailiff. The decision to pursue collection and any legal steps always remain with you.
Commonly requested features include a debtor overview with open items and ageing analysis, automated reminder and demand workflows, SEPA direct debit with mandate management (Core and B2B), payment links and online payments, instalment payment arrangements, an escalation process for handing cases to a debt collection agency or bailiff, and reporting on key metrics such as DSO and outstanding balance. Which components you need depends on your invoice types and customer groups, and we will agree on these with you.
Yes. We typically integrate the software with your accounting or ERP system, for example through an Exact Online integration, and with a payment provider for payment links and online payments, such as a Stripe integration. We also configure the SEPA direct debit files so they match your bank's requirements. This keeps invoices, payments and reminders within one coherent process, without duplicate work or manual re-keying.
Debt collection software is especially valuable for organisations with many recurring or outstanding invoices: SMEs with high invoice volumes, subscription businesses with periodic billing, associations collecting membership fees, and healthcare providers with many small claims. In all these cases, automating reminders, formal demands and SEPA direct debit saves considerable manual effort and shortens the payment cycle.
Yes. Debt collection software processes personal and payment data, so we build in line with OWASP guidelines and GDPR requirements. This includes, among other things, data minimisation, encryption in transit and at rest, role-based access, audit logging, and careful management of SEPA mandates and payment data. We document the data flows so that your record of processing activities is complete and you can demonstrate GDPR compliance.
Yes. Appfront regularly takes over and extends existing software, even when it was originally built by another party. We review the current setup of the receivables management, reminder flows and SEPA integration, document them and propose improvements. From there we can handle changes, new functionality and monitoring, so the software grows along with your organisation.
