Keep the upsell after the first yes

The buyer already said yes. The next screen then asks for the card again, and a lot of that extra revenue never lands.

One-click upsell checkout software charges that second offer to the card saved at the first sale. Choose based on where your funnel already runs: a hosted cart, a WooCommerce plugin, or a high-volume CRM checkout.

My take

I would start with ThriveCart Standard when the pages are hosted and the upsell has to be included from the first paid plan. I would skip SamCart Core for this job, because the bumps and upsells sit on Pro. For a store already running WooCommerce, I would pick CartFlows. I would judge Checkout Champ against Funnelish by the gateway count: several merchant accounts and rebills fit Checkout Champ, and one subscription that already includes the bump fits Funnelish.

Compare SamCart and ThriveCart

A flat payment card, a smaller card lifted on a thin arc above it, and a small checkbox square beside the first card. — The checkbox is the bump. The shape above the payment card stands for the extra offer, charged after the first yes.

Order bump software is the checkbox before payment

An order bump is a checkbox on the checkout, before the charge. The buyer adds it to the same order. The post-purchase offer runs after that charge, using a payment token saved at checkout.

A WooCommerce thread on post-purchase upsells draws the line in plain terms. A true post-purchase one-click upsell charges that saved token. Without the token, the buyer sees another form. A bump can sell with no second step at all. That second charge cannot run until the first sale has stored the card.

On ThriveCart, Standard allows one bump. A second bump needs Pro+. CartFlows says order bumps convert 10% to 30% of checkout buyers. That range is CartFlows' own marketing.

Checkout page software for a hosted funnel

SamCart and ThriveCart fit a digital product whose pages and cart are hosted, so there is no WordPress site to maintain.

SamCart homepage hero with the headline about stopping lost revenue at checkout, beside a SamCart AI chat window suggesting an order bump and two post-purchase upsells for a digital product. — SamCart's homepage leads with the checkout and a suggested bump.

SamCart's pricing page puts bumps and upsells on Pro, listed as everything on Core plus those two. Core leaves both off. The real entry for the post-purchase offer is Pro.

A buyer comparing upgrade flows called SamCart's order-upgrade path expensive. That is one person's report, and it lines up with the plan gap: the upsell features are the jump from Core to Pro. The longer write-up is the SamCart review.

SamCart

Pro (16 Oct 2026): $199/mo, bumps and upsells
Core (16 Oct 2026): $79/mo, neither bumps nor upsells
Trial: 7 days, card at signup

For a hosted digital checkout, when bumps and the post-purchase offer both have to be on.

SamCart pricing

ThriveCart's homepage sells the creator checkout, with a revenue dashboard beside the headline.

ThriveCart's homepage includes upsells and downsells on Standard, the plan marketed to new sellers, plus one bump. The same page advertises no platform fee on a sale for Standard and Pro+.

One long-term user reported that the post-purchase upsell had stopped working for more than two months. That is a single report, not a confirmed outage. Weigh it before you treat the upsell as guaranteed. ThriveCart's review lists the plans that allow more than one bump. Side by side, Standard already includes the upsell. SamCart waits until Pro. The SamCart vs ThriveCart comparison puts the two carts on one page.

ThriveCart

Standard (16 Oct 2026): $37/mo annual, or $47/mo monthly
Pro+ (16 Oct 2026): $67/mo annual, or $87/mo monthly
Trial: 30 days, card on file
Bumps: One on Standard, several on Pro+

For a hosted creator checkout, when Standard already includes the upsell.

Best checkout for funnels on WooCommerce

CartFlows home page headed Everything Your WooCommerce Store Needs to Sell More, in one suite, showing its four-plugin WooCommerce suite. — CartFlows presents itself as a suite that stays inside WooCommerce.

CartFlows is the plugin path. Bumps, unlimited upsell and downsell steps, and the checkout takeover run inside WordPress on a store already running WooCommerce. Paid Starter is billed once a year, and the renewal costs more. Dynamic upsells and funnel A/B tests sit on Pro. Our CartFlows review covers what Pro adds, and what a second plugin does to the same checkout.

On WooCommerce, Stripe or PayPal has to charge the saved card. Otherwise the next step is another form. Leaving Woo for a hosted cart is a different project. The ElasticFunnels vs CartFlows comparison covers that switch.

CartFlows

Starter (16 Oct 2026): From $99/year. Renewal costs more
Steps: Unlimited upsells and downsells in WordPress
Pro: Dynamic upsells and funnel A/B tests

For a store already on WooCommerce, when the checkout should remain a WooCommerce plugin.

Checkout for paid-traffic volume and rebills

Checkout Champ is the CRM checkout for a direct-response brand with substantial sales volume, several gateways and rebills. Growth is a monthly base plus a percent of gross sales processed through the platform. You book a conversation to start. That pricing page does not show a self-serve trial.

Its upsell page describes each extra product as one click after the initial sale. Buy now, pay later is the gap to price in. The same pricing page says upsell and subscription support for those services varies by the provider. More of the gateway contract sits in the Checkout Champ write-up.

Checkout Champ

Growth (16 Oct 2026): $300/mo + 1% of gross sales

Funnelish's homepage opens with a free-trial button in the header.

Funnelish is an ecommerce funnel builder that includes bumps and post-purchase offers in the subscription, with no separate app fee. The homepage says those offers, and the content builder, are included natively, and that Funnelish Pay supports bumps, quantity checkouts, upsells and downsells. It also says the platform takes no commission on a sale. Basic is the entry tier on the pricing cards, with a visitor cap and a funnel cap. The trial signup does not require a card. The visitor cap and the trial length are in the Funnelish write-up.

Funnelish

Basic (16 Oct 2026): $49/mo, 20,000 visitors, 20 funnels

Sales commission: None

For an ecommerce funnel, when the bump and the upsell are both in the subscription.

When the checkout ships with the whole funnel

Some buyers want the pages, the tests and the checkout on one bill, instead of a cart bolted onto a separate builder.

ElasticFunnels home page headline reading The sales funnel builder for paid traffic, with buttons to start a free trial and book a demo. — ElasticFunnels' homepage leads with the funnel builder and a free-trial button.

ElasticFunnels is a funnel platform for teams on paid traffic. The pages, same-URL split tests, the checkout and the order sit on one record. Its features page includes bumps and post-purchase offers on every plan, with the same split tests used on pages. A percentage fee applies only when the sale runs through its hosted checkout. A sale that goes out through an external checkout is not charged that fee.

Independent reviews are still thin. It has been around since 2023, so SamCart and ClickFunnels have more outside coverage. Until volume has run through the checkout, those feature lines are mostly the vendor's account. The pages, the tests and the order record are still the product on that features page. Against a checkout-only cart such as SamCart, this is the wider platform. The ElasticFunnels review goes further.

ElasticFunnels

Starter (11 Oct 2026): $97/mo
Trial: 14 days, no card
Checkout fee: 0.5% on its hosted checkouts only

Pages, split tests and checkout on one bill. Outside reviews are still thin.

ClickFunnels is a hosted funnel builder for course creators, coaches and info-product sellers. Smart Checkout lets a buyer add a one-time offer during checkout, with one click after the main item. That offer happens inside the checkout step. Matching the sale back to the ad still needs a separate tracker. The ClickFunnels page explains that handoff.

The checkout still has to sit beside a tracker and a VSL player. The stack picker walks through that trio.

Smart Checkout: One-time offer during checkout, one click after the main item
Attribution: Uses a separate tracker

For funnels selling a course, coaching or an info product, when the extra offer is added during checkout.

Compare the two hosted carts

If the funnel is hosted and you need to see which starter subscription includes the upsell, compare SamCart and ThriveCart.

Pro is the SamCart plan that adds the offer. Standard is the ThriveCart plan that already includes it. The rest of this page is for a store on WooCommerce, a high-volume CRM checkout, or a funnel that ships the pages with the cart.

Questions before you pick a checkout

Can Stripe Checkout alone add an order bump?

Stripe Checkout is the card page Stripe hosts. The carts on this page add a checkbox before payment and a saved-card offer after it. Those two steps are the reason to use a funnel cart.

What is the cheapest way to try an upsell?

ThriveCart opens with the trial printed on its lines above, and that trial takes a card. CartFlows is a plugin on a WooCommerce store you already run. This page does not estimate what either test saves.
