Kaching Cart vs AMP is a choice about promotion behavior as much as subscription cost. Kaching CartDrawer Cart Upsell deserves attention when a gift should enter the cart automatically after a defined condition, especially at lower order volumes where its regular fee can also be lower. AMP offers reward and upsell workflows of its own, with a documented pricing ceiling for new installs. There is one complication: AMP's billing guide now describes a different schedule from its App Store listing. Comparing these apps properly means separating new subscriptions from legacy plans, then checking how the intended gift reaches the shopper.

Comparison matrix

The AMP prices in this comparison refer specifically to its official new-install billing guide, not a promise that every existing store pays those amounts.

Shared features are only the starting point

Both apps offer an in-cart selling experience with upsells and reward messaging. A progress bar or a “free gift” label does not tell you how eligibility is calculated, whether the shopper must accept an item, or how the discount is applied. Those details determine whether a campaign can run as intended. Kaching App Store listing, AMP App Store listing.

Neither app's feature list establishes the profit from a promotion. The merchant still needs to consider the gift's landed cost, shipping impact, and the purchases that qualify.

Difference 1: automatically including a gift or offering it

Kaching's auto-add documentation describes rules that insert gift products when conditions qualify. The gift is removed if the cart stops qualifying, and the documented auto-added gift cannot be manually removed while the rule applies. This is a specific workflow, not a description of every possible Kaching promotion. Kaching auto-add rules.

Consider a skincare store promising a travel pouch with two qualifying full-size products. An automatically inserted pouch can make the promise visible without requiring another click. The relevant trial is whether the correct variants and quantities trigger the rule, and whether removing one qualifying item also removes the gift.

That behavior has a trade-off: a shopper who does not want the pouch should not be assumed to have a simple remove option under this rule. Decide whether mandatory inclusion fits the promotion before treating automation as an advantage.

AMP's documented Buy X Get Y example follows another path: a widget offers a qualifying gift for the customer to add. It also requires the corresponding Shopify discount configuration. That can suit a campaign where the shopper should actively accept the extra item. It does not establish that all AMP gifts require manual acceptance or that AMP lacks other gift workflows. AMP Buy X Get Y guide.

For the pouch campaign, Kaching supplies a documented implementation of automatic inclusion. For a sample offer that customers may prefer to decline, the AMP example provides a relevant alternative. The choice depends on the intended interaction, not on which app displays the phrase “free gift.”

Make the reward message and checkout benefit agree

A promotion can look correct in a drawer while still requiring careful configuration of the underlying offer. AMP's tiered-rewards guide distinguishes the displayed reward tiers from the Shopify discount or shipping setup needed to fulfill them. AMP tiered-rewards guide.

For example, a merchant might display a shipping milestone followed by a gift milestone. Before launching, the team needs to inspect the checkout total at each threshold, rather than approving the design because the progress indicator fills correctly. A shopper crossing a visual milestone should receive the benefit the message promises.

Kaching's documented gift conditions make it possible to describe the intended qualifying cart precisely. That is useful for a campaign limited to a collection or tagged products, but it does not justify skipping a checkout check. Test the discounted cart, not only the displayed pre-discount subtotal, and establish how the configured rule responds to it.

This distinction gives Kaching a credible place on the shortlist even where AMP's subscription is cheaper: a merchant may value a documented rule that matches the promotion. It is not a reason to pay a premium for automation the campaign will never use.

Difference 2: pricing for new AMP installs and legacy plans

AMP's App Store listing and its newer billing guide are not aligned. The listing presents Free, Growth, and Pro options; the guide gives order-based Starter, Growth, and Scale plans for new installs, while preserving older terms for existing users. Use the app's subscription confirmation to resolve the price actually offered to your store. AMP billing guide.

The following regular monthly USD examples use that new-install guide alongside Kaching's published pricing. They exclude taxes and discounts and assume each stated order count qualifies for the corresponding band.

At 300 orders, Kaching costs $5 less before the introductory offer. At 750, the listed fees tie. At 1,500, AMP's documented schedule is $20 lower. A recommendation that one app is always cheaper would miss both the thresholds and the subscription-version issue.

For an existing AMP merchant, use the actual subscription already in place as the baseline. Do not assume installing again, changing plans, or comparing with a new store reproduces the same terms. Also avoid describing the App Store's older Pro tier as a universal current requirement for gifts: the new-install guide describes all features across its paid plans.

The SSK20 offer reduces Kaching's first three months. It does not remove future order-tier changes, so forecast the regular bill at your expected volume after the offer ends.

Two merchant situations that lead to different choices

A product-specific gift campaign at roughly 300 monthly orders: Kaching combines a lower documented regular bill with an auto-add workflow worth evaluating for the campaign. Write the eligibility rule first, then confirm that the intended gift and its removal behavior match the promise made to customers.

A store expecting roughly 1,500 orders with a straightforward reward program: AMP's new-install ceiling has a clear cost advantage if that schedule is offered to the store. If its promotion controls cover the requirement, lower ongoing spend is a valid reason to choose it. Kaching warrants the extra expense only where its actual workflow solves a relevant need.

Moving a gift campaign between apps

Treat the promotion as a set of rules to recreate. Record the qualifying products, excluded items, gift variant, discount, customer-facing message, and behavior when the cart falls below the threshold. No direct configuration-transfer path is established by the sources used here.

Run a small test sequence: qualify the cart, remove an item, add an unrelated product, apply an allowed discount, and continue to checkout. Check gift stock handling for the configuration you intend to use. These are proposed validation steps, not claims that either app has passed them.

Arrange the change so only the intended drawer is active. Before removing the old app, preserve configuration details and review its billing status; uninstalling does not necessarily erase charges already incurred. Shopify's uninstall guidance.

Final verdict

A merchant planning automatic, condition-based gifts has a concrete reason to evaluate Kaching Cart now. At the lower-volume examples above, that workflow comes with a smaller regular subscription than AMP's documented new-install fee. Confirm the gift behavior that matters to your campaign, then use the introductory offer to reduce the initial cost.

For higher-volume stores whose reward needs are covered by AMP, its published new-install ceiling deserves weight. Existing AMP users should make the same decision against their own retained plan, not a generic price comparison.
