Dynamatic app projects an expert should own
Every widget can be switched on in minutes. Choosing, targeting and testing them is the paid part.
A cart built on purpose. Slide cart or sticky cart, announcement and progress bars, a terms checkbox and discount field, chosen from what your current cart already does well.
Offers that fit the margin. Buy more save more, quantity breaks, free gifts and bundles priced against cost, with CRO specialists deciding which to test first.
Paid extras in the cart. Shipping protection, warranties, gift wrap, additional fees and priority processing. Each one needs a policy behind it and a check with whoever handles tax.
Audience rules. Audience segments connected to specific widgets, with custom rules deciding who sees which offer and when.
Custom styling. Custom HTML and CSS for stores where the drag-and-drop editor isn't enough.
Speed checks. A cart loaded with widgets should be measured before and after. Speed optimization experts can confirm nothing slowed the storefront.
Use the free install. Dynamatic lists free expert installation on every plan. Take it for the base setup, then bring in outside help for strategy and testing.
How to brief a cart and upsell expert for Dynamatic
The risk with a 50-widget app is a cart that does everything and converts worse. Hire for judgment.
Ask for a widget shortlist. A strong candidate proposes three or four widgets for your store and explains what each replaces or adds. A list of twenty is a warning.
Ask about paid add-ons. Shipping protection and warranties need claims handling and clear terms. They should raise that before building the widget.
Ask how tests will run. Dynamatic has A/B testing plus click-through, conversion and funnel reports. Expect one change per test and a stated stopping point.
Ask about plan size. Pricing jumps with monthly orders, so they should check your last peak month before recommending a tier.
Ask about checkout. Checkout bumps sit on the top plan and the help center files checkout integration under Shopify Plus. Someone who promises checkout features without asking your Shopify plan hasn't read the docs.
A sensible first job. A cart audit with a shortlist of widgets, then one A/B test of a single offer over an agreed number of orders.
Dynamatic order tiers, checkout features and limits
Priced by total orders. As of October 2026 the listing shows Free up to 50 orders a month, Basic at $79.99 up to 500, Growth at $199.99 up to 1,000 and Scale at $299 up to 2,000. Dynamatic's site adds Advanced at $399.99 for 5,000 and Enterprise+ at $799.99 with no cap. Every plan includes all features, a 14-day trial and a 30-day money-back guarantee.
Overage is undocumented. Neither page says what happens above a plan's order limit. Ask before a promotion.
Checkout extras. Checkout bumps and dynamic content, plus live chat, are listed only on Enterprise+.
Checkout rules. The listing includes shipping and payment method rules, hiding express checkout, donations and custom notes. Confirm which ones your Shopify plan allows.
Cart replacement. The docs don't say how the slide cart coexists with a theme's own drawer. Test on an unpublished theme first.
Admin language. The app is listed in English, though widgets support multi-language and multi-currency storefronts.

Dynamatic app questions: plans, checkout and setup
As of October 2026 it is free up to 50 orders a month, then $79.99 for up to 500, $199.99 for 1,000 and $299 for 2,000 on the listing, with higher tiers on Dynamatic's site up to $799.99 for unlimited orders. All plans carry every feature, a 14-day trial and a money-back guarantee. Expert fees are extra.
Dynamatic prices on total monthly orders, so a busy store with few upsell takers pays the same as one where every cart converts. Run the numbers at your peak month. If upsell revenue won't cover the tier, start with fewer widgets on the free or Basic plan.
Not for the base install, which Dynamatic lists as free on every plan. A developer earns their fee on custom HTML and CSS, on a theme whose own cart drawer resists replacement, or when checkout rules have to be checked against your Shopify plan.
Yes. Audience segments connect to specific widgets, and custom rules decide when each widget shows. Keep segments few at first so each A/B test still gets enough orders to read, and add more only once a split has proved itself.
Orders per month including your peak, average order value, a screenshot of today's cart, the theme name, your Shopify plan, and any cart or upsell apps you would retire. List products you want pushed and any you never discount. That shapes the widget shortlist.
