Custom software that fits your business — plus our own Shopify apps
You shouldn't have to change how you work to fit someone else's software. We build tools that match your process, your industry, and your team.
We've been running this on spreadsheets for years and it's a mess
What started as a quick tracker is now the backbone of your operation — and it's fragile, confusing, and terrifying to update. We turn spreadsheet chaos into a proper system that your whole team can use confidently.
Every software company we've spoken to wants tens of thousands and months of our time
We're a small team with low overhead. We don't have account managers, project managers, or three layers of sign-off. You talk directly to the people building your software. That's why we can deliver real solutions at a fraction of the agency price.
Nothing on the market does what we need — our industry is too specific
Veterinary practices, specialist contractors, bespoke manufacturers, niche consultancies — we love working with businesses that the big software companies have never heard of. Your industry might be niche, but your problems are solvable.
We keep paying for features we don't use and can't get the one feature we actually need
Off-the-shelf SaaS tools are built for everyone, which means they're perfect for no one. We build exactly what you need — nothing more, nothing less. No per-seat pricing creep, no features you'll never touch.
Your clients want to check on their order, see their documents, book an appointment, or approve a design — and right now they have to ring you or send an email. A portal gives them self-service access and saves your team hours.
Generic booking tools don't understand your rules. Maybe you need specific equipment per slot, staff with different qualifications, or buffer time between certain types of appointment. We build booking that works how you work.
Salesforce costs a fortune and takes months to configure. HubSpot is built for marketing agencies. You need a CRM that speaks your language — with the fields, stages, and workflows that match your actual sales or service process.
Whether you're a workshop tracking repair jobs, a contractor managing installations, or a studio managing commissions — you need to know what's in progress, what's waiting, and what's overdue. Not in a spreadsheet. In a proper system.
The tools your team uses every day but nobody outside the company ever sees. Staff portals, stock trackers, quoting calculators, approval forms, training systems — the boring-but-essential software that makes your operation run.
You already have tools that work — they just don't talk to each other. We connect your existing systems so data flows automatically, and we automate the repetitive tasks that eat your team's time.
Fast, modern, mobile-responsive websites that load instantly and rank well on Google. We design and build every site in-house — no templates, no page builders. Every one of our 9 app websites is our portfolio in action.
Our best work is for businesses in industries too specific for generic SaaS tools. If your business has a unique process that no off-the-shelf tool handles — that's where we come in.
Don't see your industry? That's fine — we probably haven't built for it yet. Get in touch and tell us what you need.
We don't do 60-page proposals or make you sit through a sales pipeline. Here's how it works.
Tell us what's not working. We'll ask questions, suggest approaches, and be honest about whether we're the right fit. No cost, no obligation.
We give you a fixed price for a defined scope. No hourly billing surprises. No "we'll figure it out as we go." You know what you're getting and what it costs.
We build in short cycles and show you working software regularly. You give feedback, we adjust. You're never in the dark about progress.
We deploy it, train your team, and provide ongoing support. The people who built it are the same people who answer your questions.
Encrypted data, secure authentication, and GDPR compliance baked in from day one. Not bolted on as an afterthought.
Responsive design that works on desktop, tablet, and mobile. Your team and your clients can use it from anywhere.
EU-based support from the people who built it. Not a chatbot, not a ticket queue in another timezone. Actual humans who know your system.
It's your software. No per-seat licensing, no monthly SaaS creep, no vendor lock-in. We build it, you own it, full stop.

Works as a Shopify embedded app or a standalone web SaaS with a JavaScript snippet.
ThemeSweep finds code left behind in Shopify themes after apps are uninstalled. It checks the theme against the store's installed apps, highlights likely orphaned code, and backs up the theme before cleanup so merchants can recover speed without guessing which snippets are still active.
Lustriel turns a retailer's Stuller catalog into a calm, guided shopping experience — on Shopify or a hosted storefront. Shoppers choose a shape, metal, and their stones in a few clear steps and see the exact piece with a live price, while the retailer keeps full control over catalog scope, branding, media, and markups.

Absolutely. Most people come to us with a problem, not a specification. "We're drowning in spreadsheets" or "our clients keep ringing for updates" is plenty to start with. We'll help you figure out what the right solution looks like.
Not at all. You know your business and your problems — that's what matters. We handle all the technical decisions and explain things in plain English.
We've built multiple production applications that are live and used by real businesses every day — you can see them on this page. We're now offering that same capability to other businesses who need custom tools built. Same team, same standards, same tech stack.
No. We provide ongoing support and maintenance. The people who built your software are the same people who support it. If something needs fixing or you want to add features later, we're here.
Yes. It's your software. You own the code, the data, everything. No vendor lock-in, no per-seat licensing that creeps up every year. We build it, you own it.
Here's how hiring a small studio like us compares to the alternatives.
| JMS Dev Lab | Enterprise Agency | Off-the-Shelf SaaS | |
|---|---|---|---|
| Fits your exact workflow | Yes — built to match | Yes, but at 5–10x the cost | Rarely — you adapt to it |
| You talk to the builders | Always — no middlemen | Usually through a project manager | Never — you get a support ticket |
| Ongoing costs | Hosting only (you own it) | Hosting + retainer fees | Monthly per-seat pricing forever |
| Timeline | Weeks to months | Months to years | Instant (but limited) |
| Budget | Proportionate to scope | Enterprise pricing | Cheap, then creeps up |
| Features you don't need | None — we build what you need | Some bloat, but mostly tailored | Loads — you're paying for them anyway |
