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.

How long does ERP development take?

A core ERP system takes 20 to 30 weeks. A full ERP with multiple modules takes 9 to 18 months. Elsio uses phased delivery so teams can start using core modules while additional features are developed.

Why build custom ERP instead of using SAP or Oracle?

Custom ERPs cost significantly less in the long term (no per-user licensing), contain only features your business needs, integrate directly with your existing tools, and can be modified without expensive consultant fees.

Can the ERP integrate with our accounting software?

Yes. Elsio builds direct integrations with Xero, Sage, QuickBooks, and other accounting platforms for seamless financial data flow.

How do you handle data migration to the new ERP?

Elsio manages complete data migration including extraction from legacy systems, data cleaning, transformation, validation, and parallel running to verify accuracy before switchover.

Is the ERP accessible on mobile devices?

Yes. Elsio builds responsive ERP interfaces that work on tablets and smartphones, with dedicated mobile views for field workers and managers.
