Meta Business Agent bills prompt and reply together at US$2.00 per million tokens, and a message typically eats 20,000-25,000 tokens — 4 to 5 US cents per interaction, delivery included. See the math, the break-even point against a flat CRM plan, and what to measure before deciding.
Billing a customer on WhatsApp means sending the charge through chat and receiving the money outside it — no card payment inside the conversation anymore. See the real instruments (Pix key, PSP link, Payments API), what COBV is, what changed in October 2026, and what consumer law forbids.
October 1, 2026 started charging per message for service messages and in-window utility templates — the two cases that were free until September 30. Marketing didn't change. See why support conversations, not campaigns, are where the invoice grows, and how to measure the exposure.
The abandoned cart is the cheapest sale to recover, because the intent is already bought. See what causes abandonment, how to calculate what it's costing you, and how to build a recovery flow with the two safeguards that prevent charging someone who already paid.
The cost of the official WhatsApp API is the sum of Meta's per-message fee plus the platform's monthly fee. See the formula, the rates by category, cost tables by volume, and what changed on October 1, 2026.
Access to Meta's Cloud API costs nothing; what's paid is template messages delivered. See what's free, what has been charged per message since October 1, 2026, and why the 72-hour Click-to-WhatsApp window stays free either way.
An unofficial WhatsApp API occupies a linked-device slot with no contract and no warning before it breaks. See how it works internally, what it costs today, what changed on October 1, 2026, and where the real ban risk lives compared to the official API.
Social selling means building relationships with potential customers through relevant content and 1:1 conversations, instead of cold-pitching. See how the Instagram-to-WhatsApp bridge works, the 5-step strategy, and the mistakes that turn it into spam.
The company's landline that's been on the sign, the business card, and Google for ten years can (and often should) also be your official WhatsApp. See the step-by-step for call verification on WhatsApp Business, the mistakes that stall the process, and how the landline becomes a channel with multi-agent support.
