Our services in detail: what is included, who it is for, how it runs
Every engagement is delivered by one senior, UK-based technologist and starts with a free discovery call. Here is what each service covers in practice. The work spans manufacturing, distribution, wholesale and multi-company groups, using whatever fits your stack — React, Angular, Node.js, SQL and custom API layers on ERPs such as Progress OpenEdge are common.
ERP & legacy system modernisation
Keep the business rules that already work and replace the parts that slow people down. We put modern web interfaces, APIs and automation around an existing ERP or legacy platform instead of starting again.
What is included
- Review of the current system, its data and the workarounds staff rely on
- API or integration layer so new tools can read and write ERP data safely
- Modern web screens for the tasks staff do every day
- Gradual replacement of fragile spreadsheets, scripts and manual steps
Who it is for
Manufacturers, distributors and multi-company groups running a long-established ERP that still does the commercial maths correctly but is hard to use or extend.
How engagements run
We start with a discovery call and a short review, agree the first slice of work, then deliver in small releases so day-to-day operations keep running throughout.

Internal tools & customer portals
Order portals, customer dashboards and internal apps that connect directly to the systems you already run, so nobody re-keys data between them.
What is included
- Trade customer portals with account logins, account pricing and order history
- Self-service ordering, invoices, statements and document downloads
- Internal dashboards and tools for sales, operations and finance teams
- Roles and permissions that mirror how your business actually works
Who it is for
B2B businesses whose customers still order by phone or email, or whose teams juggle several systems to answer simple questions.
How engagements run
Portals are treated as a product, not a one-off website: a pilot with a small group of accounts first, then wider rollout once the data and processes are proven.

Integrations & automation
Web and system integration services that stitch together the tools your teams already use, so data moves between them automatically and reliably.
What is included
- ERP, CRM, accounting and website integrations
- Open Banking, EDI, Twilio, email and Microsoft 365 / Teams connections
- Custom APIs and connectors where no off-the-shelf option exists
- Monitoring and a clear process for when a sync fails
Who it is for
Teams copying data between systems by hand, or relying on brittle exports and imports that break without anyone noticing.
How engagements run
We map the systems and data flows first, choose the lightest pattern that fits, then build, test and monitor each integration with your operations team.

AI workflows that actually make money
Practical AI that removes manual work from quoting, customer service or operations — built on your own data and systems, not a generic chatbot.
What is included
- Finding the repetitive, rules-heavy tasks where AI can genuinely help
- AI steps wired into existing workflows, with people approving the output where it matters
- Guardrails, logging and a fallback when the AI is unsure
Who it is for
Businesses with high volumes of similar requests, documents or quotes that currently need a person to read and re-key them.
How engagements run
We start small with one workflow, check whether it saves real time, and only then extend it.
Further reading: AI vibe coding · AI vibe code audit
Customer-facing applications
Web applications and apps for your customers that hook directly into your existing systems, so what they see always matches what your team sees.
What is included
- Account areas, booking or ordering flows and customer self-service
- Live data from your ERP or back-office systems
- Secure logins and sensible handling of personal and commercial data
Who it is for
Businesses whose customers expect to self-serve online, but whose current website is disconnected from the systems that hold the real data.
How engagements run
Discovery first, then iterative releases with real users so the application earns adoption rather than being launched and forgotten.
Further reading: All case studies
Ad hoc consultation & fractional technology leadership
Senior technical advice when you need it — on architecture, technology choices, suppliers or a specific problem — without a long-term commitment.
What is included
- Architecture and code reviews
- Technology and supplier selection
- Technical due diligence
- A clear written view of scope, risks and next steps
Who it is for
Owners and operations leaders who need CTO-level judgement for a decision or project but do not need a full-time technology hire.
How engagements run
Book a session for a one-off question, or move to an ongoing fractional arrangement if you need regular senior input.

Website integration services: connecting your ERP to your website and portal
Website–ERP integration keeps orders, stock, prices and customer accounts consistent between your customer-facing website (or trade portal) and the ERP that runs the business. Most UK SMEs looking for website integration services do not need another redesign — they need the site to agree with the ERP, so the sales desk stops re-keying orders and customers stop phoning to check stock.
What we connect
- Customer accounts, logins and ship-to addresses
- Account-specific pricing and discounts, resolved by the ERP
- Live stock, including incoming stock and stock allocated to purchase orders
- Sales orders created in the ERP, with order status flowing back to the website
- Credit limits and account rules enforced at checkout
- Invoices, statements, price lists and order history
Who it is for
UK B2B SMEs — distributors, wholesalers and manufacturers — whose trade customers still order by phone or email, or whose website shows prices and stock the ERP would not agree with. It suits businesses where the ERP still does the commercial maths correctly but the web experience around it has fallen behind.
How HTML Studio delivers ERP and website integration
- The ERP stays the source of truth. We integrate a modern web layer rather than rewriting either system, so decades of pricing and warehouse rules are preserved.
- The lightest pattern that fits. Direct API calls where the ERP exposes stable endpoints, a middleware layer when several systems share the same data, EDI or custom connectors where no off-the-shelf option exists, and file drops only as a temporary bridge.
- Risk controls built in. Idempotent order posts, monitoring, clear ownership when a sync fails, and a manual replay path for the operations team — the website never accepts an order the ERP would refuse.
- Senior, UK-based delivery. One experienced technologist designs and builds the integration — no juniors, no outsourcing. Focused integrations often take 2–6 weeks; we give a realistic timeline after a free discovery call.
In production, this is what our ERP customer portal case study looks like: a portal wired into a long-established ERP for a UK B2B distributor, with live stock, account pricing and pay-by-bank checkout — over £30m of orders in 2025, with the ERP kept as the system of record. For the patterns and risk controls in more depth, read our website–ERP integration guide; if a trade portal is your next step, our B2B portal buying guide for SMEs covers what to demand from any vendor before you commit. For what the finished portal should actually do for trade buyers, see our ERP customer portal guide.

Frequently asked questions
How do you approach legacy system modernisation?
We wrap existing systems with modern APIs and UIs rather than doing full rewrites. This lets you move fast without disrupting operations. We create abstraction layers that allow new features to be built on top of legacy systems while gradually modernising the core.
Can you integrate with our existing ERP and business systems?
Yes. We specialise in system integration with ERPs, CRMs, accounting software, and custom legacy platforms. We work with APIs, EDI, file-based integrations, and build custom connectors when off-the-shelf options do not exist.
How long does a typical UK system integration project take?
Timelines depend on scope. Focused API or workflow integrations often take 2–6 weeks. Larger portal or ERP modernisation projects typically run 2–4 months. We provide a realistic timeline after a short discovery call.
What's included in ad hoc consultation?
Ad hoc consultation sessions cover architecture reviews, technology selection, technical due diligence, or expert input on a specific challenge. You get actionable recommendations and a clear view of scope and approach for potential projects.
Do you only work with UK businesses?
We are UK-based and primarily serve UK SMEs and mid-market B2B companies. Most delivery is remote across the UK, with in-person meetings available in the Midlands — including Derby, Nottingham, Leicester and Birmingham — when needed.
How do you price system integration and modernisation work?
We offer monthly subscription plans for ongoing delivery capacity, or ad hoc consultation for one-off guidance. Pricing depends on complexity and engagement model — contact us for a tailored quote after a brief discovery call.
What are website integration services?
Website integration services connect your website or trade portal to the systems that run the business — usually the ERP, but also CRM, accounting and payment systems — so orders, stock, prices and customer accounts stay consistent everywhere. The aim is to stop staff re-keying web orders and stop customers seeing prices or stock the ERP would not agree with.
Can you build a customer portal on top of our existing ERP?
Yes. We build trade customer portals that read live stock and account pricing from your ERP and write orders back into it, with the ERP kept as the system of record. Our ERP customer portal guide and case study explain the approach in more detail.
