The verdict in three sentences
For an enforcement agents' office in London with 22 staff, the vendor case management system remains the foundation (writs, client accounts, regulated fees), but it falls short as soon as you need fine-grained pre-enforcement collection or a modern creditor portal. A custom module plugged into the existing system costs EUR 25,000 to 50,000 excl. VAT (about GBP 21,500 to 43,000) and ships in 4 months. The right call is rarely a full replacement: keep the vendor for the regulated core and build what sets the office apart with institutional creditors.
What the vendor software really costs in 2026
Sector case management vendors charge per seat, with paid add-ons for electronic service, archiving and bank connectors. For 22 seats, the annual bill climbs quickly.
| Cost item (2026 ballpark) | Low end | High end |
|---|---|---|
| Licence per seat per month | EUR 250 | EUR 450 |
| Annual cost for 22 seats | EUR 66,000 | EUR 118,800 |
| Electronic service module | EUR 3,000/year | EUR 8,000/year |
| Evidential archiving (third-party archive) | EUR 2,500/year | EUR 7,000/year |
| Custom development requested from vendor | EUR 1,200/day | EUR 1,600/day |
| Lead time for a change request | 9 months | 18 months |
| Data export outside proprietary format | Paid or impossible | Paid |
The real issue is not the licence price. It is the inability to evolve pre-enforcement collection (multichannel reminders, payment plans, debtor scoring) at the pace of banks and housing associations that place thousands of debts each year.
Custom module: scope and budget
The custom layer connects to the vendor system via API or scheduled file exchanges. It does not replace document drafting, it orchestrates everything around it.
| Custom component | 2026 budget excl. VAT | Lead time |
|---|---|---|
| Collection engine (SMS, e-mail, letter reminders) | EUR 9,000 to 16,000 | 6 weeks |
| Debtor payment plans and online card payment | EUR 4,000 to 8,000 | 3 weeks |
| Creditor portal (real-time tracking, documents, reporting) | EUR 7,000 to 14,000 | 5 weeks |
| Integration with service platform and vendor software | EUR 3,000 to 7,000 | 3 weeks |
| Evidential archiving (timestamp, hash, vault) | EUR 2,000 to 5,000 | 2 weeks |
| Acceptance testing, GDPR, access logging | EUR 0 to 2,000 (partly included) | ongoing |
| Total | EUR 25,000 to 50,000 | 4 months |
Maintenance and hosting: allow 15 to 18% of the initial budget per year, i.e. EUR 4,000 to 9,000. The data stays the property of the office and can be exported at any time.
Profession-specific watch points
Professional confidentiality requires certified hosting in the relevant jurisdiction, with encryption and an audit trail of every access. The creditor portal must strictly partition cases: a landlord sees only its own debtors. Reminders must comply with enforcement regulations and permitted contact hours. Finally, evidential archiving requires qualified timestamping and a documented retention policy (10 years for most records).

Mark, a partner in an enforcement agents' office in central London, handles 9,000 cases a year, 6,000 of them at the pre-enforcement stage. Each such case takes an average of 35 minutes of manual reminders. With the automated engine, that drops to 12 minutes, saving 23 minutes per case, or 2,300 hours a year. At EUR 32 per loaded hour, that is EUR 73,600 a year. The project, billed EUR 42,000 excl. VAT plus EUR 7,000 annual maintenance, pays back in 7 months. The creditor portal also helped win two more housing associations, adding 1,400 cases a year.
FAQ
Should we drop our current vendor software?
No, in 80% of cases the vendor stays in place for writs and regulated accounts. The custom module, between EUR 25,000 and 50,000 excl. VAT, connects to it and handles collection and the portal.
How long until we are operational?
Allow 4 months from scoping to go-live, including 3 weeks of acceptance testing with case handlers. A pilot with a single creditor can start in month three.
Where is debtor data hosted?
With a certified local host, encrypted at rest and in transit. The extra cost of a high-assurance hosting tier is about EUR 150 to 400 per month.
Is a creditor portal worth it for a mid-sized office?
Yes, institutional creditors increasingly require it in tenders. It also cuts follow-up calls and e-mails to the office by 40 to 60%.
What if the vendor changes its API?
The connector sits in a dedicated layer, which limits an update to 2 to 5 days of work, or EUR 1,000 to 3,000 excl. VAT depending on the scope of the change.
