Required for open banking and e-invoicing · £149 + VAT
100% uptime on ePayment infrastructure, duplicated endpoints and 24/7 priority support. An active Enterprise SLA is required to access open banking and e-invoicing. BACS and cards remain available on standard terms.
£149 + VAT / month · £1,490 + VAT / year · 15-minute critical response
Standard accounts can run BACS and cards. To initiate open banking payments or to issue and receive structured e-invoices, the account must have an active Enterprise SLA. Per-transaction rates on those schemes still apply on top of the SLA add-on.
Why Enterprise SLA
Duplicated infrastructure and a contractual uptime credit if we fail to deliver on our side of the stack.
Required to initiate account-to-account collections. The SLA covers ePayment availability, not the payer’s bank app.
Required to issue and receive EN 16931 / Peppol invoices. The SLA covers our issue and receive path, not the buyer’s Access Point.
Guaranteed availability of ePayment infrastructure, with service credits if monthly uptime falls short.
Separate servers and endpoints, isolated from standard service traffic.
Direct line to senior engineers with a 15-minute critical response target, every day of the year.
Usage billed in arrears. Better cash flow than large prepaid packs.

Infrastructure
Isolation, redundancy and proactive operations for BACS, cards, open banking and e-invoices.
Traffic routes through endpoints isolated from standard service load. Dedicated IPs, priority routing, no shared contention.
UK primary and secondary datacentres with automatic health-based failover.
One-minute health checks, performance monitoring and ops alerts before an issue reaches you.
Redundancy
Primary path, automatic failover, then a backup DNS endpoint for the dual-failure case.
Main API path with built-in automatic failover between UK datacentres.
If the primary path fails, traffic routes to the secondary path in sub-seconds.
Manual switchover details in onboarding docs, for the improbable dual-failure scenario. 24/7 support can walk the switch.
Pricing
Same flat add-on as eValidate. Access to open banking and e-invoicing, 100% uptime on our infrastructure, and usage billed in arrears.

All prices exclusive of VAT at 20%. Scheme rates (BACS, cards, open banking, e-invoices) are billed in addition at the published unit prices.
The 100% uptime guarantee covers ePayment infrastructure — APIs, bureau processing, card gateway, open banking initiation and e-invoice issue/receive on our side. It does not cover the payer’s bank, Pay.UK, card schemes, or a buyer’s Peppol Access Point. Service credits, from 10% to 100% of the SLA subscription plus that month’s usage, are measured monthly and applied to the next invoice.
Who it is for
Anyone who needs open banking or e-invoicing, or who cannot run collections without a contracted uptime credit.
Account-to-account checkout and invoice pay-now flows. The SLA is the licence to turn that scheme on.
VAT-registered businesses that will have to issue structured invoices. The SLA is required to use the ePayment e-invoice path.
Memberships, payroll and regulated collections that already run on the bureau and want 100% uptime on our side as well.
One invoice after the month, 30-day terms, rather than prepaid packs.
Open banking, e-invoicing, or a 100% uptime contract on the stack you already run.
