Trengo is European, multi-channel-strong, expensive. InboxChange is India-first, multi-tenant, half the price. Here's the honest read.
Pick Trengo if: you're in Western Europe, your AOV is in EUR/USD, your multi-channel mix includes Facebook Messenger and Instagram heavily. Pick InboxChange if: you're in India / SEA / GCC, your primary channel is WhatsApp + Email, you run an agency, or your tooling budget is under $500/month.

WHY CUSTOMERS LEAVE
The same set of complaints we hear repeatedly when teams come to us from Trengo.
Expensive — €119/mo per agent starter; quickly hits €500+/mo
WhatsApp Cloud API support is decent but not best-in-class
Razorpay integration absent; Stripe-only (problematic for India D2C)
No native agency/multi-tenant mode
DECISION HELPER
An honest checklist. There are situations where Trengo is the right pick.
REAL CUSTOMER OUTCOME
A Bangalore-based ethnic-wear D2C brand replaced their three-spreadsheet, two-agent WhatsApp workflow with InboxChange's multi-tenant inbox + Shopify automations — and saw their abandoned-checkout recovery rate go from 4% to 19%, while support team headcount stayed flat through a 3× sales jump.
SWITCHING IS PAINLESS
Trengo → InboxChange migration: contacts and conversation history exportable via Trengo's API. Templates need to be re-submitted to Meta under InboxChange's BSP. Plan 1-2 weeks for full migration.
