Verify the exact direct-sale release, then check your real store stack.
The exact 0.8.1 ZIP is available by direct purchase. Verify its identity and isolated PS8/PS9 lifecycle, then classify the checkout surface and payment return paths you must stage-test before production.
One direct-sale release, one reproducible identity.
The delivered ZIP was rebuilt deterministically and its SHA is embedded in both lifecycle results and the browser matrix. Direct fulfillment must resolve to these same bytes.

This lab sends no event, reads no checkout, estimates no lost revenue and does not diagnose a gateway. Scenario numbers are fictional; the coverage boundary and operator workflow mirror the Sentinel embedded in NP Checkout Pro 0.8.1.
What this experience proves
You can inspect the product’s actual decision surface before buying: bounded checkout stages, grouped incidents, confidence, sanitized component hints, safe next checks and a human-controlled state audit.

Follow real shopper and merchant paths, inspect the interface at full size, then open the live demo when one is available.
A focused checkout that works down to 320 px
The order summary stays compact while contact, address, delivery and payment advance in clear stages.
- Mobile-first 16 px form controls
- Trust and payment labels are merchant-controlled
- No horizontal overflow at 320 or 390 px
This tour uses real product captures and documented behavior. It is not a performance benchmark or a promise of storewide uplift.
Check your store before you buy
Answer four release-specific questions. The result identifies what to validate next; it is not an automatic compatibility guarantee.
NP Checkout Pro 0.8.1 brings the shopper experience and checkout evidence into one product. Merchants can start from a PrestaShop-balanced, WooCommerce-inspired or Shopify-inspired presentation pattern, then personalize typography, width, density, order-summary surface, logo, color, trust badges, labels, conversion options and custom fields. These are neutral visual presets, not integrations with or copies of WooCommerce or Shopify.
Checkout Sentinel is built in, not sold as a second plugin. It records minimized local evidence from explicitly instrumented stages, groups repeated symptoms and gives an operator a safe next check. It never approves, declines, blocks or changes a payment, and its own failure cannot stop checkout.
The optional Spanish recargo de equivalencia path is off by default. It supports both individual retailers and companies with a tax ID, but only becomes actionable when a compatible local adapter owns eligibility, cart and order totals, later cart mutations, excluded goods and the separate invoice line. Without that adapter the buyer sees an honest contact fallback; NP Checkout Pro never invents a surcharge.
Full coverage applies only to the module-owned replacement checkout. Native/restyled checkout is partially observed; unknown third-party one-page checkouts, themes and gateways remain partial or unknown until tested. Version 0.8.1 is a translation-only successor to the behavior-verified 0.8.0 release (83 contract groups, 153 Sentinel assertions and a 14/14 rendered PS8/PS9 matrix); its exact ZIP separately passed 28/28 lifecycle checks on each version. The exact package is available here by direct purchase; PrestaShop Addons approval remains a separate Marketplace matter.
What it does
- Module-owned one-page checkout with a compact mobile flow, progressive sections and a distraction-free payment shell.
- PrestaShop-balanced, WooCommerce-inspired and Shopify-inspired presentation presets provide familiar starting points without claiming affiliation.
- Personalize typography, checkout width, spacing density, order-summary surface, logo size, colors, corners, trust badges, payment labels and checkout copy in a live preview.
- Custom fields become editable mobile cards and include stable hints, errors, autocomplete mappings and keyboard focus.
- Built-in Sentinel combines local funnel evidence, coverage state, incident grouping, retention controls and redacted export.
- Optional Spanish retailer-tax declaration for individual traders and companies, guarded by an explicit adapter capability contract and a no-adapter contact fallback.
- Observe-only and fail-open by design: Sentinel cannot alter checkout, gateway, order or payment behavior.
In the wild
Who this is for
Best for merchants who want to own checkout UX
Choose it when you need one-page conversion controls and local operational evidence in the same PrestaShop module.
Useful for intermittent checkout investigations
Sentinel can group repeated symptoms and preserve a sanitized timeline so an operator has a bounded place to start investigating.
Not a universal third-party checkout firewall
If your store depends on an unknown one-page checkout or gateway customization, request a compatibility review before relying on coverage claims.
Why neuroplugin
- One accountable product
- Checkout UX and evidence ship together, so merchants do not have to reconcile two products or two compatibility stories.
- Evidence without automatic blame
- Coverage, confidence and normalized component hints stay distinct from cause attribution and payment decisions.
- Release-bounded proof
- The public page names the exact direct-sale package, checksum and browser/lifecycle matrix, while keeping Marketplace approval and unknown merchant-stack compatibility as separate claims.
By the numbers
Questions answered
- Is Checkout Sentinel a separate plugin?
- No. In 0.8.1 Sentinel is built into NP Checkout Pro and shares the same merchant workspace, lifecycle and release package. The old standalone draft is not a second public product.
- Will it fully observe any third-party checkout?
- No. Full stage coverage is limited to the module-owned replacement checkout. Native/restyle mode is partially observed. Unknown third-party one-page checkout, theme and gateway flows remain partial or unknown until explicitly tested.
- Can Sentinel block or modify a payment?
- No. It is observe-only and fail-open. It does not approve, decline, disable, repair or alter checkout, order or gateway behavior.
- Does checkout evidence leave my PrestaShop server?
- The released design stores minimized evidence locally and has no external telemetry endpoint. It excludes card data, gateway payloads and direct customer profile fields from the event schema.
- Does NP Checkout Pro calculate recargo de equivalencia by itself?
- No. The optional buyer declaration is off by default and only becomes actionable when a compatible local tax-and-invoice adapter declares that it owns eligibility, cart and persisted order totals, later cart mutations, excluded goods and a separate invoice line. It can support a qualifying individual retailer or company with a tax ID; it is not a generic B2B surcharge.
- Is version 0.8.1 already approved on PrestaShop Addons?
- Not yet. Direct purchase on neuroplugin.com is available independently and delivers the exact internally verified 0.8.1 package. The Addons Product Key, official Validator and listing review affect only Marketplace distribution. A merchant’s named theme and gateway paths still need staging tests before a compatibility claim.
