The Problems That Eat Your Evenings
The spreadsheet that runs the business
Twelve tabs, one person who understands it, and a knot in your stomach every time it's open. When it breaks — and it will — there's no undo. A proper tool that replaces it starts at €3,000, fixed. Start with the spreadsheet replacement checklist.
The website you're embarrassed to share
Or the one that doesn't exist yet. Nearly half of Irish small businesses budget under €500 for a site — which is exactly where our first tier sits. One page, done properly, live in about a week.
The quotes that make no sense
One developer says €800, an agency says €12,000, and nobody explains the difference. We published a plain-English guide with real 2026 budget data so you can read any quote — including ours — intelligently.
Three Ways We Help, All Fixed-Price
Websites — from €500
One-page site (€500), small business site up to 5 pages (€1,000), self-editable site (€2,000), full online shop (€3,900). You see the finished site before you pay. Website pricing · recent build: wildatlanticbiker.com.
Custom tools — from €3,000
Job tracking, quoting, booking, stock, customer records — the workflow that's outgrown paper and Excel, rebuilt as a simple web app your whole team can use from any device. How a build works.
Honest advice — free
Describe what's not working and we'll tell you the honest fix — including "buy this off-the-shelf tool, don't hire us" when that's the truth. No call required, no sales pressure. Free software review.
We've Been the Small Business, Not Just the Vendor
Our team combines software engineering with first-hand experience of multi-location retail — staff rotas, stock, repairs, customer service, and the realities behind the dashboard. JMS Dev Lab now builds and operates 15 software products, seven approved on the Shopify App Store after independent review. Every claim on this site maps to a listing, a product, or a published price you can check.
