E-commerce

Choosing the right quantity is not always easy. The customer hesitates between a single unit, a pack, a family size, a refill, a subscription, or a professional quantity. They want to avoid running out, but also avoid waste or spending too much.
The chatbot must understand the usage, frequency, number of people, desired duration, storage constraints, and budget. It can then explain the most suitable quantity and the available alternatives.
This guide shows how to use an AI chatbot to help with quantity selection, without systematically pushing for the largest cart.
Summary
Why does quantity influence the customer experience?
Too small a quantity creates a quick shortage and repeated delivery costs. Too large a quantity can be expensive, take up space, expire, or not match the customer's actual consumption rate.
The chatbot must find a balance between convenience, budget, and usage. This assistance is particularly useful for consumables, family products, refills, and recurring purchases.
The right quantity is the one that matches the customer's consumption rate, not the one that increases the basket value in the short term.

What information should be requested?
The bot can ask for the frequency of use, the number of people, the desired duration, storage space, budget, date of need, purchasing habits, and the preference between a one-time purchase and a subscription.
It must remain lightweight. A few pieces of information are often enough to suggest a reasonable quantity.
How to compare unit, pack, and family size?
The chatbot can explain the price per unit, the estimated duration, the delivery fees, the potential savings, and the storage constraints. It must also indicate if the product has an expiration date or a storage condition.
The family size is not always the best choice. For a first try, a small quantity might be more prudent.
How do I offer a subscription?
The subscription is useful if the need is regular and predictable. The bot must explain the frequency, the possibility of pausing, modifying, canceling, discounts, and reminders before shipping.
It must not present the subscription as mandatory if a one-time purchase is sufficient. The customer must retain control.
How to manage professional quantities?
If the customer requests a large quantity, the chatbot must check stock, lead times, potential discounts, delivery, billing, and the possibility of a quote.
It must transfer volume requests rather than promising an unconfirmed price or availability.
Which flow to follow?
The flow must recommend an appropriate quantity, not just a larger one.
Identify the product, usage, frequency, number of people, and desired duration.
Compare unit, pack, family size, refill, or subscription according to the need.
Explain price per use, storage, shelf life, delivery, and flexibility.
Recommend a quantity with a simple justification.
Forward professional volumes, quotes, critical stock, and special requests.
Which messages should be used?
To advise: "If you use it every week, this set will cover about [duration] depending on your pace."
For caution: "For a first try, the smaller size may be more suitable."
For subscription: "If your need is regular, a subscription can prevent forgetting while remaining modifiable according to the rules in place."
When to transfer?
The transfer is necessary if the client requests a high quantity, a professional discount, a quote, a special delivery, guaranteed availability, or specific invoicing.
The bot must transmit the product, quantity, usage, deadline, country, visible stock, budget, professional need, and exact request.
Which KPIs should be monitored?
Follow recommendations regarding quantity, chosen formats, activated subscriptions, returns due to excess, rapid stockouts, quote requests, and dropouts related to bulk price.
These data show whether the proposed formats truly correspond to customer use.
Which mistakes should be avoided?
Avoid pushing the largest batch by default, ignoring conservation, hiding subscription terms, or promising a stock volume without verification.
The chatbot must help the customer buy the right quantity, not just a higher quantity.
How can Qstomy help?
Qstomy can connect the chatbot to orders, catalog, QR codes, quality statuses, customer preferences, quotes, and support rules to answer clearly, then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without inventing a redirect, a quality status, a quantity, a price, or a commercial condition that still needs to be confirmed by a reliable source.
