Common questions
What is ROAS for WhatsApp ads?
Return on ad spend — the revenue from WhatsApp sales divided by what you spent on the ads. Above 1x means you recovered your spend; above 3x is a healthy margin for most Kenyan shops.
How do I know which WhatsApp chat came from an ad?
Only Click-to-WhatsApp chats are attributed to ads in Meta. Organic chats from your link or bio are not counted as ad conversions, so track them separately.
Does Timi change my Meta costs?
No. Meta bills its per-conversation fees separately. Timi helps you see which ad chats became M-Pesa sales so you spend on what actually converts.
Should I keep scaling if ROAS is below 1x?
Not yet. Fix the funnel first — faster first reply and clean qualification usually lift return without more spend. This is where a WhatsApp platform helps.
