Post-purchase · AI upsell agent

Turn one order into two. A friendly call that sells the add-on.

Your best buyer is the one who just bought. Callsy calls recent customers with a relevant upsell or cross-sell, a subscription offer, or a bundle, and closes it on the call with a one-tap link. Pure incremental revenue on an audience that already trusts you.

Who it's for

  • Brands with natural add-ons, refills, or accessories
  • Stores that could convert one-time buyers to subscriptions
  • High-AOV products where a bundle lifts order value
  • Anyone leaving post-purchase revenue on the table

How it works

  1. 1

    Customer completes a purchase

    A few days after delivery, when the customer is enjoying the product, Callsy calls with a relevant, well-timed offer. Not a hard sell, a helpful suggestion.

  2. 2

    Adam makes the offer

    He references what they bought, suggests the natural next product or a subscription, and answers questions. The recommendation is tuned to their order, not a generic blast.

  3. 3

    Close on the call

    Interested? He sends a one-tap checkout link by SMS or email while they're still on the phone. No friction, no re-entering details.

Why it works

  • The post-purchase window is the highest-trust moment you'll get with a customer.
  • Voice lets the agent read interest and tailor the offer, which a blast email can't.
  • Subscription conversion on the call turns a one-time buyer into recurring revenue.
  • Every offer is on-brand and relevant, so it builds the relationship instead of annoying.

Hi Sofia, it's Adam from Lumio. I'm an AI assistant. How are you getting on with the desk lamp you ordered last week?

Customer

Oh, I love it actually. Brightness is perfect for my home office.

Adam

That's great to hear. A lot of customers pair it with our daylight bulb 2-pack for the early mornings. Want me to send a link with 15% off for being a recent buyer?

Customer

Sure, go on then.

Adam

Sending it by SMS now, one tap to check out. Thanks Sofia, enjoy the lamp.

Frequently asked

Won't customers find an upsell call annoying?

Only if it's badly timed or irrelevant. Callsy calls a few days post-delivery with an offer tuned to what they actually bought, in your brand voice, and discloses it's AI. Done well, a relevant recommendation reads as service, not spam, and customers can opt out instantly.

Can it convert one-time buyers to subscriptions?

Yes, that's one of the strongest plays. For consumables and refillables, Adam offers the subscription on the call and sends the sign-up link by SMS or email, turning a single purchase into recurring revenue.

How does it know what to offer?

The offer is driven by the customer's order and rules you set: complementary products, the next item in a range, a bundle, or a subscription. You control the catalogue logic; the agent personalises the conversation.

How is the discount or link handled?

If you offer an incentive, the agent sends a one-tap checkout or sign-up link by SMS or email during the call, with the discount pre-applied. No codes to remember, no details to re-enter.
