What is Closer by Flatzer?

Closer is an AI sales agent that handles inquiries, recommends products, and closes sales on WhatsApp around the clock. It sets up in 5 minutes and requires no technical knowledge.

How does it recover abandoned carts?

Closer detects when a customer leaves items in their cart without completing the purchase and sends an automatic WhatsApp message with a reminder and, optionally, a personalized offer to encourage the sale.

Can it process voice notes?

Yes. Closer transcribes and analyzes your customers' voice notes to understand their inquiry and respond contextually in seconds. No manual intervention needed.

How long until it's live?

Under 5 minutes. Paste your store URL so Closer learns your catalog, connect your WhatsApp Business, and it starts handling inquiries immediately. Fine-tune the tone and rules later, at your own pace.

What types of businesses benefit most?

Online stores, course and coaching sellers, clinics, service agencies, and any business that receives customer inquiries on WhatsApp and wants to convert more sales without hiring more staff.

Why a subscription instead of a one-time payment?

Because Closer isn't a plugin: it's an AI agent running 24 hours a day on its own isolated server for your store, with real infrastructure and AI model costs every month. You pay while it sells for you, and you can cancel anytime — no lock-in. You also start with a 7-day trial: you add your card, pay nothing today, and can cancel before it ends at no cost.
