Questions
Can't find your answer? Ask us on WhatsApp.
Can an AI agent really handle my customers?
It handles the routine questions and orders that take most of a seller's day, and passes anything unusual to a person on your team or ours. You can read every conversation.
Do the agents speak Bangla?
Yes. The chat agent replies in Bangla, English or Hindi, matching the customer. The voice agent makes and answers calls in Bangla.
I have a full-time job. Can you run my whole shop?
Yes. The done-for-you shop covers everything after sourcing: content, page and store, ads, orders, delivery and reports. You approve the plan and the ad budget, and we run the rest.
