Custom Software for Property Management
Tenant Portals, Rent Tracking, Maintenance. Built for lettings agents and property managers who have outgrown spreadsheets but don't need enterprise software costing tens of thousands.
Seven apps live on the Shopify App Store. Based in Cork. Fixed price builds.
The Problems Every Growing Property Business Hits
You started with a few properties and a spreadsheet. It worked. Then the portfolio grew and the cracks started showing.
Rent tracking is a spreadsheet with colour-coded cells
Green for paid, yellow for late, red for overdue. It works when you have ten properties. At thirty, it's a liability. You can't see arrears trends, you can't generate reports for landlords automatically, and the formula that calculates total outstanding rent broke two months ago and nobody noticed.
Maintenance requests come in by email, phone, and text
A tenant emails about a leak. Another rings about a boiler. A third sends a text with a photo. There's no single place to track what's been reported, what's been assigned to a contractor, and what's been resolved. Things get missed, tenants get frustrated, and landlords ask why the response time is so slow.
Tenants ring every week asking the same questions
When is my lease up? Can I see my payment history? Has the maintenance request been actioned? Every phone call takes ten minutes. Multiply that by fifty tenants and you've lost days every month answering questions that a self-service portal would handle automatically.
RTB compliance paperwork is scattered everywhere
Registration dates, notice periods, deposit protection records, inspection reports. Some of it is in the filing cabinet, some in email, some in a folder on the desktop. When the RTB asks for documentation, pulling it together takes hours. A proper system would have it all in one place.
We can't tell landlords what their vacancy costs are
A property sits empty for six weeks between tenancies. What did that actually cost? Lost rent, advertising, cleaning, repairs, re-letting fees — when none of this is tracked systematically, you can't give landlords the financial picture they need. And they're asking for it more and more.
Custom Tools for Property Management
Not generic SaaS designed for the American market. Not enterprise software with features you'll never use. Tools built around how Irish lettings agents and property managers actually work.
Property Dashboards
See your entire portfolio at a glance: occupancy rates, rent collection status, upcoming lease renewals, outstanding maintenance, and financial summaries. One screen instead of seven spreadsheets.
Tenant Portals
A branded login where tenants can view their lease details, check payment history, submit maintenance requests with photos, and download documents. Cuts phone calls dramatically and gives tenants the self-service they expect in 2026.
Rent Collection Trackers
Track payments across every property and tenant. See who's paid, who's late, and who's in arrears. Generate landlord statements automatically. No more colour-coded spreadsheets.
Maintenance Request Systems
Tenants submit requests through the portal. Each request is logged, assigned to a contractor, tracked through to completion, and documented with photos. Nothing falls through the cracks. Full audit trail for every issue.
Financial Reporting
Generate landlord reports showing rental income, expenses, maintenance costs, and vacancy losses. Give your landlords the financial visibility they need without manually assembling reports from three different sources every month.
Compliance Management
Track RTB registrations, BER certs, inspection schedules, and notice periods. Get reminders before deadlines hit. Keep all compliance documentation in one searchable, auditable system.
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 Property Management: Common Questions
What does JMS Dev Lab build for property management?
JMS Dev Lab builds custom software for lettings agents and property managers in Ireland: tenant portals, rent tracking, maintenance-request systems, and property dashboards. Tools are built around how you actually manage properties — fixed-price, EU-hosted, and GDPR compliant. It's for agencies that have outgrown spreadsheets and email but don't need expensive enterprise property platforms.
How much does custom property software cost?
Builds are fixed-price, quoted in full before any work starts — no hourly billing or scope-creep surprises. Replacing a spreadsheet with a proper web app starts from €3,000 (about 3–4 weeks); tenant portals and multi-feature tools from €6,000 (4–8 weeks); end-to-end systems 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: typically 3–4 weeks for a single tool and 4–8 weeks for a tenant portal or multi-feature system. JMS Dev Lab builds in short cycles so you see progress and give feedback early.
Can tenants report maintenance and check things themselves?
Yes. A tenant portal lets renters log maintenance requests, upload photos, view documents, and check status, which cuts down the calls and emails your team fields every day. You see every request in one dashboard with a full audit trail.
Is tenant and property data kept secure and GDPR compliant?
Yes. 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.
Do you work with agencies outside Cork?
Yes. JMS Dev Lab is based in Cork and works with lettings agents and property managers across Ireland, and remotely beyond. The first conversation is free and with no obligation, and we'll be honest about whether custom software is the right fit.
