When choosing a WooCommerce checkout plugin, weigh six things: verified HPOS compatibility (not merely a header flag), attribution that survives custom thank-you URLs, proper GDPR consent at checkout, no lock-in when you deactivate, classic-hooks compatibility with your theme, and a price that does not climb as you add features. One well-scoped plugin usually beats a stack of single-purpose ones, because fewer plugins means fewer conflicts and one update path — provided it does not trap your data when you leave.

## Start with the traps, not the features
Feature lists all look similar. The differences that bite show up later: a plugin that breaks your ad tracking, one that quietly drops order data when you enable HPOS, or one whose price triples once you need the feature you actually bought it for. Choose against the traps first.
## The six questions that matter
### 1. Is HPOS compatibility verified, or only declared?
WooCommerce is moving orders into High-Performance Order Storage. A plugin can carry the HPOS-compatible flag in its header while its code still reads orders the old way. Ask whether compatibility is enforced in the build, not only asserted. [Why this matters →](/why/hpos-code-verified)
### 2. Does attribution survive a custom thank-you URL?
If you use a custom thank-you page — and most stores do — check that the plugin re-fires the purchase event there. Otherwise your sales complete but your ad platforms never see them, and you optimise against bad data.
### 3. Is GDPR consent handled properly at checkout?
A cookie banner is not checkout consent. If you sell to the EU, EEA or UK, look for an unbundled marketing opt-in separate from accepting the terms, recorded with the policy version that applied.
### 4. What happens when you deactivate?
Some plugins leave your store altered or your data stranded when you turn them off. A clean exit — vanilla WooCommerce returns, settings preserved — tells you the plugin respects that it is a guest in your store.
### 5. Does it fight your theme?
Plugins built on classic WooCommerce hooks tend to play well with classic themes; some block-first approaches do not. Match the plugin to how your store is actually built.
### 6. Does the price scale with you or against you?
Map the price to the features you need now and in a year. Watch for the feature you are buying it for sitting behind the top tier.
## One plugin or several?
A stack of single-purpose plugins — one for the side cart, one for the shipping bar, one for trust badges — multiplies conflicts and update work. One plugin covering cart and checkout reduces both, as long as it does not lock you in. That is the case Asteris Cart makes: 22 modules in one plugin, with a clean deactivation path.

## FAQ
**What should I look for in a WooCommerce checkout plugin?**
Verified HPOS, attribution that survives custom URLs, proper GDPR consent, no lock-in, theme compatibility, and a price that does not balloon.
**Is one plugin or several smaller plugins better?**
Usually one well-scoped plugin — fewer conflicts, one update path — provided it does not lock you in.
**Does HPOS compatibility matter?**
Yes. Verified compatibility matters more than a header flag.
