InterPay + DDMS review
A mature UK-focused system for recurring Bacs collections, mandates and submissions.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
InterPay + DDMS is a web and API service for organisations managing recurring direct debit collections in the UK. InterPay handles payment-file validation and submission through Bacstel-IP, while the multi-user Direct Debit Management Software supports mandate management, automated collection, schedules, monitoring, alerts and reporting. It is positioned for SMEs, enterprise businesses and channel partners that need structured control over recurring payments and Bacs submissions.
Its strongest fit is the connection between operational collection work and Bacs processing. Teams can create, edit and cancel mandates, set weekly, monthly or quarterly payment plans, monitor transactions in real time and receive alerts for payment events or collection issues. Reporting covers direct debit transactions and Bacs submissions. Accounting-software integration and tailored APIs also give it a practical role alongside existing finance systems, while the hosted payment page supports payment collection workflows.
The trade-off is focus: InterPay + DDMS is centered on domestic Bacs processing rather than broad international scheme coverage. Pricing is handled through a contact-sales model, with variation by payment volume, so organisations must discuss requirements before comparing costs. Businesses choosing a UK recurring-collection platform with mandate lifecycle controls, Bacstel-IP submission and accounting or API connectivity should find the feature set relevant. Those needing multi-country direct debit schemes or transparent self-serve pricing should consider alternatives with those priorities.
