One system for the whole agency, or the missing pieces added to the tools you already use. What we can build for you:





Six modules from Propvexa, live today — the same building blocks we shape around your agency.

WhatsApp, Instagram and Messenger in one place, with the lead’s budget, labels and viewings beside every conversation.

Buyers by stage, budget and source, a clock on every lead still waiting for a first reply, and routing rules for the team.

A visual builder for the AI assistant: it asks for budget and area, sends matching listings, offers viewing times and hands over to an agent.

Viewings, meetings and calls in one calendar. Double bookings for the same agent or unit are refused unless a reason is recorded.

Sale reports go to review first. Only approved agency sales count as confirmed deals, with commission splits.

The agency edits its own pages and sections, and the site can list the same properties the CRM manages.
Leads arrive from portals and social DMs, listings go out to the portals, and viewings land in your team’s inboxes and calendars — without anyone copying data between tabs.
Portal and messaging connections use your own business accounts and each provider’s approval process. We set them up with you.
Agencies, developers and landlords run very different businesses. We start from how yours works and build only what it needs.

CRM, shared inbox, portal feeds, viewings, approvals and commission for agent teams.

Unit inventory by project, broker access, and sales tracked from first enquiry to reservation.

Tenants, leases and renewals, maintenance requests, work orders and owner documents.
Four steps, with a working version in your hands early — so your team shapes the software, not the other way round.
We sit with your agents and managers and map listings, leads, viewings, approvals and commission as they really happen today.
You see clickable designs of the boards, calendars and forms your team will use, and sign them off before we build.
We build in short cycles you can test, and wire in your portals, WhatsApp, email and calendars along the way.
We import your existing contacts and listings, train the team and go live — then plan the next phase with you.
Inbox, leads, listings with portal feeds, viewings, deal approvals and an agency website builder — live today at propvexa.com.
Straight answers to what agencies, developers and landlords ask us first.
Every project starts from your process, not a template. Having built Propvexa, we already know the hard parts — portal feeds, viewing clashes, approval flows and commission splits — so more of your budget goes on what makes your business different.
