The 1,000-Reply Meter

The safest mental model separates four ideas. Permission decides whether a free-form reply is allowed. Classification decides whether a message is Service, Marketing, Utility or Authentication. Delivery is the billing event. Allowance decides how many Service messages are covered before the rate applies.

This is why “the 24-hour window is free” is no longer a safe budget assumption. The window remains essential, but it is a permission mechanism—not an unlimited zero-price zone.

When a customer sends a message at 10:00 AM, a rolling 24-hour customer-service window opens. If the same customer messages again at 4:00 PM, the window resets from that newer message. While it is open, an agent, chatbot or AI assistant may send free-form replies. Once it closes, a business generally needs an approved template to restart business-initiated communication, together with the required customer permission and policy compliance.

A Service message is a non-template business reply sent while the customer-service window is open. It could be an agent answering “Where is my order?”, a bot sharing branch timings, an AI assistant answering a product question or a support team requesting another photo.

Text, images, documents, audio, video and interactive replies can each be delivered messages. If a bot breaks one helpful answer into five bubbles, the system may create five metered replies. The same useful answer written clearly in one bubble can create one. Billing is tied to delivery, not the blue read tick.

A sales offer does not become a Service message merely because the sender calls it customer care. Meta's category rules consider message purpose and content. Keep the format decision and the cost decision separate.

WAB2C displays partner-BSP rates in PKR and Meta-direct list rates separately. The BSP figure is a local partner-route price, not an official conversion of Meta's USD list rate. Direct billing can also involve exchange-rate movement, card or banking costs and applicable taxes.

Service pricing applies after the first 1,000 eligible Service messages per registered business number per calendar month. Always confirm the live WAB2C pricing page and current Meta documentation before approving a high-volume budget.

Ask one question first: did the customer message within the last 24 hours? If yes, a free-form Service reply is permitted. Count the delivered reply against that number's monthly allowance and charge only the amount above 1,000. If no, an approved template is normally required, where policy and opt-in allow it.

The WAB2C subscription covers the software and operating layer—Team Inbox, agents, contacts, automation flows, AI assistance, analytics, API access and integrations according to the selected plan. Message-provider charges sit beside that subscription, not inside it.

Six-month billing is displayed as pay for five months; annual billing as pay for ten. Plan limits can change, so use the live pricing page as the final source.

The goal is not to make every conversation unnaturally short. It is to remove waste while preserving a useful human experience. A concise answer that resolves the customer's question is better than a maze of confirmations, repeated greetings and one-line bot bubbles.
