Custom Software for Professional Services
Client Portals, Practice Tools, Workflow Automation. Built for accountants, solicitors, and consultants who have outgrown spreadsheets and email but don't need enterprise software costing six figures.
Seven apps live on the Shopify App Store. Based in Cork. Fixed price builds.
Most agencies configure Shopify. We pass its app-review process. Getting an app approved on the Shopify App Store is a higher technical bar than building a store — and we've cleared it 7 times. When we build your custom software, you're hiring the team that ships approved, production software, not a theme tweak. See how we shipped seven approved apps as a solo studio.
The Problems Every Growing Practice Hits
You started with email, spreadsheets, and a shared drive. It worked. Then the practice grew and the cracks started showing.
We're emailing documents back and forth with clients
Version three of the tax return is somewhere in someone's inbox. The client sent corrections by reply-all. The trainee is working off the wrong file. You know this is a problem, but there's no obvious fix that isn't a massive enterprise system.
Our client tracker is a spreadsheet with 30 tabs
It started as a simple list. Now it tracks deadlines, fees, contact details, compliance dates, and notes. Two people can't edit it at the same time. Nobody trusts the formulas. But migrating to a CRM designed for estate agents doesn't make sense either.
Billing takes a full day every month
You're pulling time entries from one system, checking them against another, manually creating invoices, and then chasing payments by email. It's a full day of admin that could be two clicks if the right tool existed.
Compliance checklists live in someone's head
Anti-money laundering checks, client onboarding steps, annual filing deadlines — these are critical processes that depend on one person remembering to do them. When that person is on leave, things get missed. A proper system would catch it.
Clients keep ringing to ask for updates
Every phone call asking "where are we with the accounts?" takes ten minutes. Multiply that by twenty clients a week and you've lost a day. A simple client portal where they can check status would eliminate most of those calls.
Custom Tools for Professional Practices
Not generic SaaS. Not enterprise software with a thousand features you'll never use. Tools built around how your practice actually works.
Client Portals
A branded login where your clients can upload documents, check the status of their work, view invoices, and download completed files. No more email ping-pong. No more phone calls asking for updates.
Practice Dashboards
See everything that matters at a glance: active clients, upcoming deadlines, outstanding fees, work in progress. Built around your practice's workflow, not a generic template.
Billing & Fee Trackers
Track time, generate invoices, and follow up on payments — all in one place. Integrates with your existing accounting software. Turns a full day of admin into a few clicks.
Compliance Tools
AML checklists, client onboarding workflows, filing deadline trackers, and audit trails. The processes that are too important to live in someone's head or on a paper checklist.
Document Management
Secure document upload, version control, and organised storage. Clients upload directly to the right place. Your team always works off the latest version. Everything has an audit trail.
Workflow Automation
Automate the repetitive steps: client reminders, document requests, status updates, and follow-ups. Your team focuses on the work that actually requires expertise.
From Conversation to Working Software
No 60-page specification documents. No six-month timelines. We keep it simple.
We Have a Conversation
You tell us what's not working. We listen, ask questions, and figure out whether we're the right fit. No jargon, no sales pitch. Over a call or a coffee in Cork — your choice.
We Build It With You
You see working software within weeks, not months. We build in short cycles so you can give feedback early and often. No disappearing for three months and hoping for the best.
You Use It, We Support It
We hand it over, train your team, and stick around. Real support from the team that built it — not a call centre in another country.

Custom Software for Professional Services: Common Questions
What does JMS Dev Lab build for professional services firms?
JMS Dev Lab builds custom software for accountants, solicitors, and consultants in Ireland: client portals, practice dashboards, billing and fee trackers, AML and compliance checklists, document management, and workflow automation. Each tool is built around how your practice actually works — fixed-price, EU-hosted, and GDPR compliant. It's for firms that have outgrown spreadsheets and email but don't need six-figure enterprise systems.
How much does custom software for a practice cost?
Builds are fixed-price, quoted in full before any work starts — no hourly billing or scope-creep surprises. Replacing a single spreadsheet with a proper web app starts from €3,000 (about 3–4 weeks); client portals and multi-feature tools from €6,000 (4–8 weeks); end-to-end custom solutions from €12,000 (8–12 weeks). You get the exact number up front.
How long does a build take?
Most projects ship working software within weeks, not months. A spreadsheet-replacement app is typically 3–4 weeks, a client portal 4–8 weeks, and a larger end-to-end build 8–12 weeks. JMS Dev Lab builds in short cycles so you see progress and give feedback early, rather than disappearing for months.
Is the software GDPR compliant and where is the data hosted?
Data is hosted in the EU and the software is built to GDPR requirements, with access controls, audit trails, and secure document storage. As an Irish studio based in Cork, JMS Dev Lab works to Irish and EU data-protection standards by default.
What makes JMS Dev Lab different from a web agency?
JMS Dev Lab builds and runs its own software, not just client sites — seven of its apps are approved and live on the Shopify App Store, a higher technical bar than configuring a store. You work directly with the developer who builds and maintains your tool, with fixed pricing and a plain-English quote up front.
Do you work with firms outside Cork?
Yes. JMS Dev Lab is based in Cork and works with professional practices across Ireland, and remotely beyond. The first conversation — by call or in person in Cork — is free and with no obligation, and we'll be honest about whether custom software is the right fit for your practice.
Our Guarantee: Scope Match or You Don't Pay
We agree on a clear scope before work starts. If the delivered software doesn't match the agreed scope, you don't pay the final instalment. The price we quote is the price you pay — no surprise charges, no scope creep invoices, no "we underestimated so you owe more."
Every project includes milestone check-ins so you see working software throughout — not just at the end. See our published fixed prices.
