Custom Software Development
Off-the-shelf software forces your business to work the way it wants to.
Web applications, internal tools and customer portals built around your process instead of around a vendor's template.
Custom applications, system integrations, e-commerce platforms and automation — designed around how your business works, built to be maintained, and supported after launch.
Software we build and run, in production today
Commerce platforms we build and maintain
And the stack underneath
Where most of our work starts
If you recognise your own situation below, the page it links to explains exactly what we would do about it.
Data re-typed between systems, documents processed by hand, reports rebuilt every Monday.
Automation & AIThe ERP, the store and the CRM each hold a version of the truth, and none of them agree.
IntegrationsUndocumented, business-critical, and the person who built it left. Every change is a gamble.
Legacy ModernisationYou are paying for a tool that does 80% of the job and blocks the 20% you actually compete on.
Custom SoftwareContract pricing, freight rules, dealer tiers, regulated products — the things standard apps cannot do.
E-commerceDeployments are manual, monitoring is absent, and the backups have never been restored.
Cloud & DevOpsAnswering a simple question means exporting from several systems and reconciling by hand.
IntegrationsThe model worked. Permissions, error handling, monitoring and the exception path did not exist.
Automation & AIWhat we do
Not a menu of thirty overlapping services. These are the six areas we have shipped repeatedly, and each one names the problem it removes.
Off-the-shelf software forces your business to work the way it wants to.
Web applications, internal tools and customer portals built around your process instead of around a vendor's template.
Your store can't do the one thing your business model depends on.
Replatforms, B2B commerce, checkout and pricing logic, ERP and fulfilment integration on Adobe Commerce, Shopify and BigCommerce.
Two systems hold the same data and disagree about it.
ERP, CRM, e-commerce, shipping, accounting and third-party platforms connected with reconciliation, retries and monitoring.
Your team repeats manual work every week that software should be doing.
Document processing, data extraction, routing, reporting and support automation — built with AI where it earns its place, and without it where it does not.
Nobody has looked at your infrastructure since it was set up.
AWS and Azure infrastructure, deployment pipelines, monitoring, backups, security hardening and ongoing production support.
Shopify does not do the one thing your business needs, and no app on the store does it either.
Public App Store apps, private and custom apps, Shopify Functions, theme app extensions and checkout extensibility — built to pass review and survive Shopify's release cycle.
The system works, but nobody will touch it.
Old, undocumented, business-critical applications made safe to change again — incrementally, without a big-bang rewrite.
Proof
Three engagements with a problem, a build and a measurable result. Where a client has not authorised naming, the business is described rather than named.
Lab Alley
Selling regulated chemicals online means pricing, shipping and compliance rules no off-the-shelf store supports — and shipping costs nobody could account for.
DAR Transport
Quote, dispatch, track, deliver and invoice in one platform — starting with a signed audit of what the company actually hauls.
KFC, Pizza Hut & Yum — Kenya
The only endorsement an agency cannot write for itself: the client rolled the platform out to a second brand, then a third.
Thirty minutes with a senior engineer, no sales script, and a rough range before you leave the call.
Why Eye4Tech
Every agency says it is senior, experienced and reliable. Here is what we can actually point at.
Most of what we are brought in for is an existing system — undocumented, in production, and unsafe to break. Reading someone else's architecture and changing it without stopping the business is the harder half of this work, and it is most of what we do.
Winning a project is easy. Keeping the same client shipping for nine years is not, and it is the number worth asking any agency for.
No account layer between you and the person who understands the decision you are asking about. The people in your discovery call are the people writing the code.
ERP, CRM, commerce, shipping, payments and finance systems, connected with reconciliation and monitoring rather than a nightly job that fails silently. Most business software problems are integration problems wearing a different hat.
We run production environments for clients we built for years ago — including one we were brought into after a breach, and never left. Software you cannot maintain is not finished.
Repository in your organisation from the first commit, documentation as a deliverable, credentials transferred at handover. There is no commercial lock-in holding the relationship together.
How we work
Seven steps, in order. The point of showing them is that you should know what you are agreeing to before you agree to it.
We learn how your business actually works, including the steps nobody has written down.
We look at what exists — code, data, integrations, infrastructure — and report what we find.
Scope, architecture, and a plan with a first release small enough to be useful quickly.
Built in visible increments. You use working software throughout, not at the end.
Automated tests plus your team on real scenarios, before anything reaches production.
Released behind a flag with a rollback path. No cutover weekends unless there is no alternative.
Monitoring, updates and enhancements — or a documented handover if you take it in-house.
Technology
Only platforms we support in production today. We would rather tell you something is outside our range than learn it on your project.
Before you get in touch
Answered here so the first call can be about your project instead of about us.
Free consultation
Bring us the problem rather than a specification. A senior engineer will look at it and tell you how we would approach it — the likely shape, the risks worth knowing about, and a rough range.
Or email info@eye4tech.com — a senior engineer replies, usually within one business day.
