How long does it take to integrate autonomous AI agents into an SME's existing workflows?

Typically 6 to 12 weeks. Elsio's AI integration engagement follows three phases: a two-week Data & Process Audit; a four-to-six-week Agent Build Sprint using Python-based LLM orchestration (LangChain or LlamaIndex) connected via secure REST or GraphQL API gateways; and a two-week supervised deployment and fine-tuning window. The result is a fully documented, GDPR-compliant autonomous agent running within a UK Sovereign Cloud environment, with measurable efficiency gains typically realised within 90 days of contract signature.

What is the realistic ROI of commissioning bespoke software versus continuing with off-the-shelf SaaS tools?

For a UK SME utilizing multiple fragmented SaaS licences, a bespoke solution typically achieves payback and delivers net-positive ROI rapidly. Beyond licence consolidation, Elsio clients on average reclaim significant staff-hours per week per department by eliminating manual administrative processes. The tech stack — Next.js, Node.js or Python microservices, PostgreSQL with schema isolation, AWS or Vercel — is selected to minimise infrastructure overhead whilst maximising scalability and preventing vendor lock-in.

How does Elsio ensure GDPR compliance when deploying AI automation systems for UK businesses?

GDPR compliance is embedded at the architectural level. Elsio's AI systems operate within a UK Sovereign Cloud boundary — all inference, storage, and processing occurs on infrastructure within the UK or EEA. PostgreSQL schema isolation ensures per-client data separation. We produce a Data Processing Agreement for every engagement, conduct DPIAs for AI processing activities, and maintain full audit logs of automated decisions to satisfy Article 22 accountability requirements. Data minimisation guardrails are built into the prompt engineering layer.

Can Elsio migrate an existing monolithic system to a cloud-native architecture without operational downtime?

Yes. Elsio executes cloud migrations using a Strangler Fig pattern: new microservices are built incrementally around the existing monolith, with live traffic progressively routed to the new architecture over a 10-to-20-week migration window — guaranteeing zero operational downtime. We target AWS (ECS Fargate, RDS Aurora, S3, CloudFront) or Vercel, with Terraform-managed infrastructure-as-code for full auditability. Post-migration, clients consistently report page load reductions from 4–8 seconds to under 800 milliseconds and infrastructure cost reductions of 25–40%.

What is a Headless e-commerce architecture and why should UK retailers consider it?

A Headless e-commerce architecture separates the storefront presentation layer from the commerce backend — enabling commerce experiences across web, mobile, voice, and in-store channels via a single unified API, free from monolithic platform constraints. Elsio-built headless storefronts on Next.js App Router, Medusa.js or commercetools, and Stripe achieve LCP under 1.2 seconds (3× faster than monolithic equivalents), higher conversion rates, and native integration with autonomous AI agents for personalised recommendations, predictive inventory, and automated customer service.

Can Elsio integrate with Open Banking APIs?

Yes. Elsio builds integrations with UK Open Banking Implementation Entity-compliant APIs for account information services and payment initiation services. Solutions support connections to all CMA9 banks and additional ASPSP providers.

How does Elsio handle PCI DSS requirements for payment processing?

Elsio designs payment systems to minimise PCI DSS scope by using tokenisation and hosted payment fields from certified payment service providers. Where direct card data handling is required, systems are built to PCI DSS Level 1 standards.

What AML and KYC capabilities can Elsio build?

Elsio builds automated AML systems including identity document verification, PEP and sanctions list screening, adverse media checks, transaction monitoring with configurable rules, and Suspicious Activity Report generation for NCA submission via the SAR Online portal.
