How an agency tracks each client's ad leads on WhatsApp

Each client has one number, and each number is an instance in your account, isolated from the others. Instead of opening a phone per client, the agency sees the status of all numbers in a single dashboard and tracks who is connected and who dropped. The cost is R$15 per active number per month, prepaid, with no per-message fee. For organizing dozens of numbers, see how an agency organizes dozens of numbers.

The Tracking module logs the lead that arrived through a click-to-WhatsApp ad and keeps, on its record, the source and the conversation timeline. Setting up the Meta Pixel and token is up to the account owner, and reach depends on how the ad was created, so validate with a small campaign before promising the client anything.

With the lead record, the client's team stops asking "how did you find us?" and the agency starts seeing, per client, which campaigns bring conversations that move forward and which bring the merely curious.

Meta optimizes better when it knows who bought, not just who replied. When the sale closes, it can be marked in the dashboard, by the client in the portal, or by API when payment is confirmed in their system. The call below logs the sale of an ad lead; repeating it for the same sale does not duplicate the event.

Use the real event and value, on the real closing date. An inflated value or a fake event worsens campaign optimization instead of improving it.

The end client rarely wants a complex dashboard. The client portal opens by link or by number and password, on the phone, and shows leads, sales and the chart for the period. The client also confirms sales and reconnects the QR code if the number drops, without a ZapZap account. The agency chooses which sections each portal shows, and the name, logo and color are the client's own.

The Performance tab, which exists on the instance and in the portal, shows response time, where the sale stalls, when people arrive and which conversations need a reply or recovery. For the agency it is the strongest argument for the support conversation: the ad delivered the lead, and response time shows where it went cold.

With leads, sales and response time per client, the monthly meeting shifts from "is the campaign good?" to "of the conversations that came in, how many became sales, where did they stall and what changes in support or in the creative".
