UK Market SaaS Development Capabilities

Purpose-built features for British data protection, financial regulations, and payment standards

GDPR Full Compliance

SaaS architecture built for strict UK GDPR compliance under the Data Protection Act 2018. Lawful basis tracking for every data processing activity, Data Protection Impact Assessments, data subject access request automation, right to erasure workflows, data breach notification pipelines within 72 hours, and ICO-ready documentation.

Open Banking Integration

SaaS products with Open Banking API connectivity via TrueLayer, Plaid UK, or direct ASPSP integration. Account information services for bank balance verification, payment initiation services for direct bank transfers, variable recurring payments, and real-time financial data aggregation compliant with PSD2 and FCA Open Banking standards.

GBP & UK Payment Methods

SaaS billing built for the British market with Stripe UK for GBP subscriptions, Direct Debit via GoCardless for recurring B2B payments, Faster Payments integration, VAT calculation and HMRC-compliant invoicing with Making Tax Digital support, and self-service subscription management for UK SaaS buyers.

AWS London Region (eu-west-2)

Production infrastructure deployed on AWS eu-west-2 (London) to meet UK data residency requirements post-Brexit. Multi-AZ deployments for high availability, data sovereignty compliance for UK government and enterprise clients, CloudFront with UK edge locations for sub-50ms latency, and options for Azure UK South as an alternative.

FCA Regulatory Awareness

SaaS architecture designed with Financial Conduct Authority considerations for fintech and financial services products. Strong Customer Authentication readiness, transaction monitoring hooks, regulatory reporting data structures, and audit trail infrastructure that meets the scrutiny of FCA-regulated clients and their compliance teams.

UK Business Culture Fit

SaaS products designed for British business expectations. Professional, understated UI design with proper English localisation (colour, organisation, favourite), GBP-denominated pricing displays, VAT-inclusive and exclusive price toggles, Companies House integration for business verification, and GMT/BST timezone-aware scheduling features.

Success Stories from UK SaaS Companies

"Edesy built our property management SaaS with full GDPR compliance, Open Banking rent collection via TrueLayer, and Companies House integration for landlord verification. Our DSAR automation handles tenant data requests in under 24 hours, which our legal team calls best-in-class. The cost was roughly a quarter of London agency quotes."

F&

Founder & CEO

Founder at PropTech SaaS, London

"We needed a B2B invoicing SaaS with GoCardless Direct Debit, Making Tax Digital integration for HMRC, and VAT calculations that handle the complexities of UK reverse charge and zero-rated services. Edesy delivered all of this in 7 weeks with impeccable attention to British regulatory detail. Our accountant clients love it."

HO

Product at Accounting SaaS, Manchester

"Our compliance training SaaS serves 150+ UK financial firms under FCA oversight. Edesy built the audit trail and certification tracking system that our clients' compliance officers specifically requested. The data residency on AWS London and ICO-ready GDPR documentation made enterprise sales significantly easier."
