When a customer reaches the delivery step, the module evaluates all active policies against the current cart, customer and delivery address. Each carrier reference receives a SHOW or HIDE decision before options are rendered.

Filtering runs through PrestaShop's checkout lifecycle — delivery option list hooks, carrier display hooks and a front-office compatibility layer that keeps themes and one-page checkout modules working. The same policy engine drives every PrestaShop version from 1.7 through 9.

A policy is a named bundle of conditions plus a set of carrier rules. Create as many as you need — express limits, B2B-only methods, country restrictions, high-value order protection.

Inside each policy, every PrestaShop carrier gets its own rule card. Toggle SHOW or HIDE, set evaluation priority and reorder display position. Write optional unavailable messages per language.

Policies run in position order. Enable Stop on first match when the first matching policy should decide everything.

Cart total (tax incl.) in this module means products plus the evaluated carrier's shipping — the number that matters for "order value" rules at the delivery step.

Products total counts product lines only, without shipping. Use it when you want to hide a method based on merchandise value alone — for example free shipping only below €100 of goods regardless of delivery price.

Both fields are available in the visual condition builder with full comparison operators. When a rule targets a specific carrier, Cart total automatically includes that carrier's shipping price in the evaluation.

When multiple rules inside one policy target the same carrier, the merge strategy decides the outcome:

• Deny wins — any matching HIDE rule hides the carrier.
• Allow wins — any matching SHOW rule shows the carrier.
• Priority cascade — the first matching rule by priority decides.
• Weighted score — SHOW adds +1, HIDE subtracts −1; net score determines visibility.
• Unanimous SHOW — all matching rules must be SHOW for the carrier to appear.

Set a default merge strategy globally in Settings, then override per policy when a specific scenario needs different conflict resolution.

Sometimes hiding a shipping method without explanation frustrates customers. Conditional Shipping Method Rules lets you write a per-rule, per-language message that appears when a carrier is blocked.

In Settings, choose between two behaviours: remove hidden carriers from the list entirely, or keep them visible as disabled options with your custom message inline on the delivery step.

Each rule card includes a multilingual input with a language flag selector — write the explanation once per language, the correct version shows automatically at checkout.

The Simulator tab lets you test rules against real carts from your shop. Search and select an active basket, optionally attach a customer, then run the evaluation.

Results show every carrier with its final visibility status, per-carrier shipping-aware totals, matched policies and unavailable messages. No test order required. No customer impact.

Use the simulator after every policy change to confirm your rules behave exactly as intended before customers see them.

The Dashboard tab is your carrier visibility control room. KPI cards summarise evaluations, hidden applications and active policies over a selectable period (30, 90, 180 or 365 days).

Chart.js trend charts break down activity daily, weekly or monthly. A per-carrier table shows which shipping methods are hidden most often — useful when tuning rules or renegotiating carrier contracts.

Recent audit entries appear at the bottom of the dashboard for quick access to the latest decisions without leaving the overview.

Every significant event is recorded: visibility evaluations at checkout, order validation blocks, policy create/update/delete, imports, exports, duplicates, settings changes and simulation runs.

The dedicated Audit log admin tab under Shipping gives you filters by date, event type and carrier reference. Click preview on any row to see the full detail payload.

Export the log to CSV when compliance or internal review requires a complete history of who changed what and when.

Download any policy as a portable JSON file from the policy editor or the policies list. Upload JSON to create a new policy on the same shop or a staging environment.

The duplicate action copies the full policy — conditions, carrier rules, merge strategy and multilingual messages — under a new name. Ideal for creating seasonal variants or testing changes safely.

Built-in condition presets speed up policy creation. Every import, export and duplicate action is logged in the audit trail.

Rules are enforced at display and again when the order is validated. If a customer bypasses the delivery list, the order is blocked before it is created — with a redirect back to checkout and a clear error message.

A structured visibility snapshot is stored on every order so support can see which carriers were hidden, which were allowed and which policies applied — directly in the order detail panel.

The module works with the default PrestaShop checkout out of the box. If your theme or a third-party one-page checkout module (OPC, Supercheckout, etc.) uses non-standard markup, optional custom CSS selectors in Settings let you point the front layer at your carrier radio buttons and row containers.

The same policy engine and visibility API power every integration path — standard checkout, custom themes and heavily modified delivery steps.
