Overview
Fluid Checkout is a checkout optimisation plugin for WooCommerce built by Diego Versiani and sold by Fluid Checkout OÜ. Rather than a funnel builder, it focuses on making the standard checkout easier to complete, with a cleaner layout and fewer distractions. The free Lite edition is on WordPress.org and a PRO licence adds design templates and extra pages.
How it works
After activation Fluid Checkout reorganises the existing WooCommerce checkout into a multi-step or single-step layout. It asks for shipping before billing, hides optional fields behind “add” links, validates fields instantly, lets customers log in without leaving checkout and saves entered data in the session. Widget areas let you add trust badges. It works with your theme and payment gateways rather than replacing them.
Free vs paid
Lite covers the optimised checkout itself. PRO adds four design templates (Classic, Boxed, Split and Minimalist), express checkout buttons above the steps, optimised cart, order-pay and order-received pages, cart editing at checkout, account matching, local pickup, gift messages and international phone fields. The PRO+ bundle adds the Google Address Autocomplete, Address Book and EU-VAT Assistant add-ons. Prices are in euros and include one year of updates; PRO features keep working if you do not renew.
Strengths
- Lite is a genuinely useful free checkout improvement.
- Focused, lightweight approach that keeps native WooCommerce behaviour.
- Declares both HPOS and Cart/Checkout blocks compatibility.
Limitations
Fluid Checkout has no order bumps, upsells, cart abandonment emails or analytics of its own; it relies on compatible third-party plugins for those and for custom fields (for example ThemeHigh’s Checkout Field Editor). It does not let you design the checkout in a page builder, and it swaps the block Checkout for its own layout.
Fluid Checkout is best for stores that want a cleaner, faster-to-complete checkout without the weight of a funnel builder, and are happy to add other plugins for upsells or recovery.
Best for: Stores that want a cleaner, easier checkout with minimal overhead and are not looking for funnels or upsells.
Fluid Checkout does one job well: it makes the WooCommerce checkout clearer and quicker to finish, and the free Lite version is enough for many stores. If you need bumps, upsells or recovery emails you will have to combine it with other plugins.

How many sites use Fluid Checkout?
Free installs from WordPress.org, the vendor's own claim, and our estimate of paid installs.

Estimated Pro / paid installs
~3K
Our estimate, see method below.
How we estimated this: The vendor figure (20K+) is within WordPress.org's rounding of the free installs, so it says nothing about paid sites. About 25K free installs x 12% (the usual share of free sites that also run the paid version when some key features are paid, and store owners upgrade more often) gives 3K. Likely range: 1.5K to 6K. This counts sites running the paid version, including sites whose licence has lapsed. Estimates are rough and based on public figures as of 14 Oct 2026.
