A large format may seem more economical, but the customer wants to understand the real savings: price per unit, duration of use, shelf life, frequency of purchase, and risk of waste. The best choice is not always the largest format.
The chatbot must compare formats clearly, explain the price relative to usage, and help the customer choose according to their actual need, not just based on the displayed discount.
This guide shows how to answer customer questions about savings by format with pedagogical clarity and transparency.
Summary
Why can savings by format be misunderstood?
The customer sees a higher total price and a promise of savings. They must understand whether the benefit comes from the price per kilo, per liter, per unit, per dose, or the frequency of replacement.
The chatbot must therefore translate the format into concrete use. Savings only make sense if the customer actually consumes the volume before expiration or loss of quality.
The best format is the one that reduces the actual cost without creating waste or unnecessary constraint.

What information should be compared?
The bot can compare total price, unit price, quantity, estimated duration, frequency of use, shelf life, packaging, delivery, storage, and any potential subscription discounts.
It must also check whether the formats are strictly comparable. A formula, concentration, or included accessory can change the comparison.
How do you explain pay-per-use pricing?
The chatbot can calculate or present the price per dose, per application, per wash, per month, or per unit depending on the product. This approach is more useful than a simple percentage discount.
If the calculation depends on personal use, it must be presented as an estimate and not as a guarantee.
How to avoid making the wrong choices?
A large format may be less suitable if the product expires quickly, takes up too much space, is intended for a test, depends on an uncertain taste, or requires low frequency. The chatbot must know how to recommend a smaller format when it is more reasonable.
This honesty strengthens trust in future recommendations.
How do I manage subscriptions and top-ups?
Savings can also come from a subscription, a refill, a bundle, or a pack. The bot must compare the conditions: commitment, frequency, pausing, returns, stock, fees, and post-promotion price.
It must avoid presenting a subscription as always cheaper if the frequency does not match the customer's need.
Which flow to follow?
The flow must compare savings and actual usage.
Identify the product, available sizes, price, quantity, usage, and client frequency.
Compare total price, unit price, estimated duration, shelf life, and delivery.
Explain the savings in cost per use rather than as an isolated percentage.
Recommend the appropriate size based on budget, storage, testing, or actual consumption.
Escalate contradictory prices, B2B calculations, complex subscriptions, and ambiguous promotions.
Which messages should be used?
To compare: "The large size is more expensive to buy, but the price per use may be lower."
For caution: "If you are discovering the product, a smaller size may be more suitable before switching to the large size."
For subscription: "I check the price after promotion and the frequency before comparing the actual savings."
When to transfer?
The transfer is necessary if the price per unit seems contradictory, if a promotion changes the calculation, if the customer requests a professional volume, or if a comparison involves non-equivalent formats.
The bot must transmit the product, formats, price, promotion, quantity, usage, expected calculation, and point of doubt.
Which KPIs should be monitored?
Track questions on large formats, conversions to economical formats, returns due to unsuitable volumes, triggered subscriptions, price comparisons, and complaints about displayed savings.
This data shows whether the savings are understood and credible.
Which mistakes should be avoided?
Avoid systematically pushing the largest size, hiding preservation constraints, comparing different formulas, or promising savings without a clear calculation.
The chatbot must help choose the most logical format for actual use.
How can Qstomy help?
Qstomy can connect the chatbot to social media campaigns, the catalog, volume pricing rules, economy formats, carriers, bulky products, professional addresses, and support procedures to answer clearly, and then transfer sensitive cases with an actionable summary.
The chatbot helps the customer move forward without inventing a product link, wholesale discount, real savings, special delivery, or corporate reception that has yet to be confirmed by a reliable source.

Key takeaways
Key takeaways
Savings by format must be explained with unit price, duration, usage, preservation, storage and subscription conditions.
What the customer must understand
The customer must know if the large format is truly advantageous for their needs.
The right limit of the chatbot
The chatbot can compare formats, but it must transfer contradictory prices, ambiguous promotions, B2B and complex calculations.
