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

- Anyone leaving post-purchase revenue on the table
How it works
- 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
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
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.

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.
