The credit price, from 2p to 1p, converts those credits to pence. BACS bureau submission is £99 + VAT per month or £1,000 per year, and it is included with an Enterprise SLA. New or re-onboarded mandates are 35p down to 20p. Collections and payments are free. New DDMS customers, October to December 2026: setup and configuration is £494, was £990 + VAT.
