Why

At 10–50 inquiries/month split across three channels and 4–10 agents, the math is brutal: any single lead has a ~10% chance of landing with the wrong agent or no agent. WhatsApp leads in particular are invisible to the team unless they're logged somewhere central. Singapore real estate cycles are short and high-ticket — a lead that waits 6 hours has usually already WhatsApped two other agents.

What you actually need

1. Pipedrive (S$19/user/mo, Essential tier) — one shared pipeline: New → Contacted → Viewing Booked → Offer → Closed. Every agent sees every lead, owner field is mandatory.
2. Respond.io (from ~S$110/mo for the team) — connects your WhatsApp Business number to Pipedrive so agent chats auto-log against the lead record. This is the piece that stops WhatsApp from being a black box.
3. A habit — the 9am lead huddle (10 min) — team lead opens Pipedrive filtered to "New, unassigned" and "Next action overdue", assigns or reassigns on the spot. Daily, non-negotiable.

Do this today

Sign up for Pipedrive at pipedrive.com (14-day free trial, pick Singapore region), create one pipeline named "Buyer Leads" with the five stages above, and invite your 4–10 agents by email from Settings → Manage Users. Then connect your web form via Pipedrive's "Web Forms" feature (Leads → LeadBooster → Web Forms) so every submission lands as a record with no agent touching it. By tomorrow morning every web form inquiry is in one place with an owner.

What to ignore

Skip Salesforce Real Estate Cloud and HubSpot Sales Hub Professional — both are priced for teams 3x your size and will take six weeks to configure. Ignore Follow Up Boss and LionDesk too; they're US-market tools with no real WhatsApp integration, which is half your lead flow. Anyone pitching you PropertyGuru's agent CRM add-on at this stage is selling lock-in, not workflow.

What doing nothing costs you

A conservative 15% slippage on 30 inquiries/month = ~4-5 lost leads. At a S$8,000-12,000 average commission per Singapore residential transaction and even a 20% close rate, that's roughly S$80,000-120,000/year of commission your team is leaving on the table through bad handoffs.

Where this leaves you

You've got Pipedrive, Respond.io, and a daily huddle. The plan defines the lead-routing rules for WhatsApp vs referral vs web form, schedules the rollout across your 4–10 agents with named owners per channel, and flags the week-two moment when one senior agent quietly stops logging WhatsApp chats and the whole system starts to rot from the top.

When to revisit this

When two agents start arguing about who "owned" the same referral lead — that's the signal your routing rules need teeth, not that the tool is broken.
