The verdict in three sentences
For a debt collection agency handling 6,000 cases a year, off-the-shelf case management software remains the safest base for compliance and client accounting. A custom build pays off on the parts that waste time every day: a client portal, automated chasing, and per-client performance dashboards. Budget a market estimate of 40,000 to 120,000 GBP for a well-scoped custom layer, which breaks even once it frees at least half a full-time collector.
What collection software costs in 2026
Specialist vendors charge per seat on subscription, with add-ons that pile up quickly (payment portals, dialler integration, credit bureau lookups, archiving). For an agency with 18 seats, the annual bill easily exceeds 40,000 GBP.
| Cost item | 2026 market estimate | Comment |
|---|---|---|
| Case management licence per seat | 150 to 400 GBP / month | Workflow, client accounting, audit trail |
| 18 seats over 12 months | 32,400 to 86,400 GBP / year | Depending on tier and options |
| Advanced pre-legal chasing module | 3,000 to 9,000 GBP / year | Often billed separately |
| Vendor client portal | 2,000 to 6,000 GBP / year | Limited customisation |
| Data migration | 5,000 to 15,000 GBP | One-off |
| Staff training | 1,500 to 4,000 GBP | 2 to 4 days |
The real hidden cost lies elsewhere: re-keying between the software, client emails and tracking spreadsheets. Across 6,000 cases, 6 minutes of re-keying per case adds up to 600 hours a year, about a third of a collector's time.
Off-the-shelf, custom or hybrid: the comparison
The hybrid model dominates in 2026: the core platform keeps compliance, client money accounting and regulatory reporting, while a custom layer plugs in via API or scheduled imports for the client experience and automated pre-legal recovery.
| Criterion | Off-the-shelf only | Full custom | Hybrid (platform + layer) |
|---|---|---|---|
| Upfront cost | 5,000 to 15,000 GBP | 150,000 to 280,000 GBP | 40,000 to 120,000 GBP |
| Annual cost | 32,000 to 86,000 GBP | 15,000 to 40,000 GBP maintenance | Licence + 8,000 to 20,000 GBP |
| Time to go live | 1 to 3 months | 9 to 14 months | 3 to 5 months |
| FCA and client money compliance | Built in and updated | Must be built and maintained | Stays in the platform |
| Custom client portal | Limited | Full | Full |
| Regulatory risk | Low | High | Low |
| Multichannel chasing (SMS, email, letter) | Basic | Complete | Complete |
A full rebuild only makes sense for a group running several collection businesses. For a single agency, rewriting client money handling and regulated reporting is expensive and exposes you every time FCA guidance changes.
The features that actually pay back
Three components concentrate the gain. The client portal lets landlords, lenders and utilities upload cases, track progress and download documents without calling your team. The chasing engine sequences SMS, email and letters on a configurable calendar and stops automatically as soon as a payment lands. The per-client dashboard shows recovery rate, average time to payment and remittances, which large creditors now require in their tenders.
On compliance, the layer must follow UK GDPR (retention periods, access logs), FCA Consumer Duty expectations on fair treatment of customers in arrears, and client money segregation. UK hosting with ISO 27001 or Cyber Essentials Plus is the expected standard.

Illustrative example: James, managing director of a collection agency in London, handles 6,000 cases a year for 35 regular clients. His collectors spend an average of 10 minutes per case answering status requests by phone and email, which is 1,000 hours a year. A client portal with automated chasing, priced at 85,000 GBP in this scenario, cuts that time by 60%, saving 600 hours. At a loaded cost of 32 GBP an hour, the gain is 19,200 GBP a year. Add 2 points of pre-legal recovery on 8 million GBP of placed debt, at an average 10% contingency fee, and that is 16,000 GBP more. Payback comes in roughly 29 months, faster if the portal helps win one new institutional client.
FAQ
Can we keep our current case management platform?
Yes, and it is recommended. The custom layer connects via API or scheduled file exchanges, and you keep your compliant core system. In about 80% of hybrid projects, no migration of historical case data is required.
How long to launch a client portal?
Allow 10 to 16 weeks for a first version with case upload, tracking and documents. Automated chasing and dashboards add 4 to 6 weeks.
Do regulated processes have to be rebuilt?
Not in the hybrid model: client money accounting and regulatory reporting stay in the vendor platform, which the vendor keeps current. The custom layer only displays balances, so you avoid tracking every rule change.
What maintenance budget should we plan?
A market estimate of 15 to 20% of the build cost per year, so 12,750 to 17,000 GBP for an 85,000 GBP layer. That covers hosting, security patches and minor improvements.
Does UK GDPR complicate the portal?
It sets clear rules: strong authentication, access logs, purging closed cases after the retention period. These requirements add roughly 10% to the development budget.
