The challenge
An interior design firm had a referral arrangement with a Mumbai developer for post-possession leads but the handoff was broken — the developer sent a contact list every quarter, the firm cold-called, conversion was 6%. By the time most buyers were called, they had already booked another designer or finished the work themselves.
How we deployed
- Triggered a WhatsApp message to the buyer 7 days before possession — co-branded developer + design firm.
- Offered a free in-home consultation with one-click calendar booking.
- Followed non-bookers at day +14, +30 and +60 with relevant before-after content.
- Synced consultation outcomes back to the developer CRM for joint attribution.
- Reminded confirmed consultations T-24h and T-2h on WhatsApp to crush no-shows.
What changed
- Cross-sell conversion lifted from 6% cold-call baseline to 38% on the new workflow.
- 1,400 buyer handovers engaged across 9 months.
- Average signed project value of Rs 6.8 lakh — premium kitchen and full-home packages.
- No-show rate on consultations fell 51% with WhatsApp reminders.
- Developer-side renewed the partnership for two more towers on the back of buyer satisfaction.
"Buyers used to forget us by the time they had their keys. Now we are in their WhatsApp before the developer hands over, and they actually expect our call."
