Listings typed more than once
Property details, photos, floor plans and material information are entered in the CRM, adjusted for each portal and corrected again whenever something changes.
Property, lettings & PropTech

Industry challenges
Where property teams get buried in admin.
Agencies and property managers rarely lack software. They lack software that shares data — so the same address, tenant and certificate get typed into three different systems.
Good first projects
- One listing record that feeds every portal
- Compliance dates tracked with automatic reminders
- Repair requests triaged and tracked in one place
- Landlord and vendor portals that answer routine questions
Enquiries arriving from everywhere
Portal leads, website forms, emails and calls land in different inboxes, and slow replies lose applicants and vendors to the agent down the road.
Lettings rules that keep moving
Tenancy law, notice requirements and landlord obligations change over time, and differ between England, Scotland and Wales — admin tools built on fixed templates struggle to keep up.
Compliance dates on spreadsheets
Gas safety records, EICRs, EPCs, licences, deposit protection and right-to-rent follow-ups tracked by hand, where one missed date becomes a real problem.
Repairs run by phone and email
Tenants report issues however they can, contractors chase approvals, and landlords ask for updates that nobody has time to send.
Clients who want to see progress
Landlords want statements and repair updates, vendors want viewing feedback, and buyers want to know where their sale has got to — without ringing the office.
Solutions
What we build for property businesses.
For agencies, property managers and developers — and the PropTech products that serve them. We add to your CRM or property management system where it works, and replace the spreadsheets where it does not.
Landlord, tenant and vendor portals
Statements, documents, repair tracking, viewing feedback and sales progress in a secure portal your clients can use from their phone.

Listing feeds and CRM integrations
Listings sent to Rightmove, Zoopla and OnTheMarket to each portal’s feed specification, and applicants, viewings and offers kept in sync with your CRM.
Learn more
Lettings compliance tracking
Gas safety, EICR, EPC, licensing, deposit protection and right-to-rent records in one place, with reminders before anything lapses and evidence you can export.
Learn more
Maintenance and repairs ticketing
Tenant reporting with photos, triage, landlord approval limits, contractor booking and job updates, so every repair has an owner and a history.
Learn more
Valuation and market data tools
HM Land Registry price paid data, EPC register data and your own comparables brought into one view to support valuations — the agent or valuer still sets the figure.

PropTech MVPs and SaaS
Scoped first releases for property products — lettings platforms, tenant apps, block management tools — typically planned over weeks, not months, with a roadmap for what comes next.

AI use cases
Practical AI for agents and property managers.
AI that drafts, reads and sorts, so negotiators and property managers can spend their time with people — and a person approves anything that goes to a client, contractor or portal.
Listing description drafts
Draft property descriptions from the details, room measurements and photos you provide, in your house style. The agent checks every claim before anything is published.
Enquiry triage
Sort portal and website enquiries into buyers, tenants, vendors and landlords, pick out budget, timing and position, and suggest viewing slots for staff to confirm.
Tenancy and lease pack extraction
Read tenancy agreements and lease packs and pull out parties, dates, rent, break clauses, review dates and service charge terms into structured records for checking.
Repair request classification
Classify reports by trade and urgency from the tenant’s description and photos, flag damp, mould and safety issues for immediate human review, and suggest a contractor.
Viewing feedback summaries
Turn scattered viewing notes into a clear weekly update for each vendor or landlord, drafted for the negotiator to edit and send.
Plain-English property search
Let users search the way they talk — “two bedrooms, outside space, near a station” — mapped onto your listing data and filters they can still see and adjust.
Technology & integration
Built around the systems you already use.
Most agencies already run a CRM or property management system and send data to the portals. We integrate through published APIs and feed specifications, and tell you early if a supplier limits what is possible.

Security & data
How we handle tenant and client data.
Property files hold passports, bank details, references and home addresses. Here is how we build with that data by default.
Access by role and branch
Negotiators, property managers, landlords, tenants and contractors each see only what their role needs, with leaver steps built into the admin screens.
ID documents handled carefully
Right-to-rent and AML documents stored encrypted, visible to as few people as possible, and deleted on the retention schedule you set rather than kept forever.
Encrypted and backed up
Encrypted in transit and at rest, backed up, and hosted in UK regions when your data protection policy requires it.
A history of every change
Changes to tenancies, deposit records and compliance dates are logged with who and when, so disputes and complaints can be answered from the record.
Staff sign off AI drafts
AI-drafted listings, replies and classifications are suggestions. A named member of staff approves anything sent to a portal, client or contractor.
Less personal data sent to AI
Personal details are removed or masked before AI processing where the task allows, and we use providers and settings that do not train on your data.
We are a software development company, not a lettings compliance service, law firm or regulator. We build to the requirements your compliance lead, legal adviser and redress scheme set — including changes to tenancy law — and provide the technical evidence they ask for. Decisions and sign-off stay with your business.

All case studiesHow we work
How we build while your branches keep trading.
Seven stages, the same on every project. The length of each one changes with the work; skipping one never saves time for long.
- 01
Discovery
We sit with negotiators and property managers, list every system and spreadsheet in play, and pin down which compliance dates, documents and approvals the new software must track.
Process map and data inventory
- 02
Strategy
We agree what to fix first — often feeds, reminders or repairs — and what can wait, so the first release is useful on its own before any bigger platform decisions.
Phased roadmap with a fixed-price first release

UX & architecture
User journeys, wireframes and a clickable prototype, alongside the architecture, data model and integration plan that will carry it.
Prototype and architecture decisions
- 04
Development
Two-week sprints with a demo at the end of each, code review on every change, and a staging environment your team can use.
Working software every sprint
- 05
Testing
Portal feeds are tested against each portal’s requirements, data migrations are rehearsed on a copy of your records, and landlord and tenant screens are checked for accessibility.
Feed test results and a migration rehearsal

Launch
We go live branch by branch or portfolio by portfolio, migrate records with a reconciliation report, and keep the old system readable until you are happy to switch it off.

Optimisation & support
After launch we fix, measure and improve — a support retainer, a roadmap of next features, or a clean handover to your own team.

FAQs
Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
Can you send our listings to Rightmove, Zoopla and OnTheMarket?
Yes. Most agencies already send listings through their CRM, and we can build on that. PropTech products that need their own feed can have one built to each portal’s specification — portals run their own onboarding and testing for feed providers, which we plan into the timeline.
Will you replace our CRM or work with it?
Usually we work with it. If your CRM or property management system has an API, we add what it lacks — a landlord portal, a repairs flow, a compliance tracker — and sync data both ways. Replacing core agency software is a bigger decision, and we would only suggest it after discovery.
How do you handle changes to tenancy law?
We make tenancy types, notice templates, reminders and required fields configurable rather than hard-coded, so a change in the rules is a configuration update rather than a rebuild. England, Scotland and Wales each have their own tenancy law, handled as separate configurations. Your compliance lead or solicitor decides the rules; we build them in.
Can your software run right-to-rent and AML checks?
It can prompt and record them. We integrate with identity verification providers and the Home Office share code process used for right-to-rent checks in England, store each result with its date, and schedule follow-up checks for time-limited permission. The check and the decision stay with you.
Is AI-written listing copy safe to publish?
Only after an agent has checked it. AI drafts save time on wording, but they can get facts wrong, and agents are responsible for accurate listings and material information. We build the workflow so a named person approves each description before it reaches a portal.
Can you build a PropTech MVP?
Yes. A paid discovery sprint, from £2,000, agrees the smallest product that proves your idea; we then build it as a fixed-price project. A typical MVP takes around six to ten weeks, depending on scope and on integrations such as portal feeds, payments or identity checks.
Can you migrate data from our old property management system?
Yes. We map the old data to the new structure, clean duplicates and rehearse the migration on a copy first, with a reconciliation report covering properties, tenancies, balances and documents. Some older systems only export part of their data, so we check exports during discovery.
How much does property software cost?
It depends on scope and integrations. Discovery starts from £2,000; after that, each release is quoted as a fixed price with milestone billing. For ongoing work, a dedicated developer starts from £2,900 a month, or you can book hours from £20 an hour.
