Next Day Shipping Eligibility for Magento 2

Comprehensive stock-aware shipping restrictions in one module.

Two independent rules, one admin section, one license:

1. Next-day eligibility (auto-managed) — removes configured next-day shipping methods from checkout when any cart item is out of stock or otherwise ineligible. Eligibility is auto-maintained by a stock observer; nothing for the merchant to flip per product.
2. Backorder express restriction (opt-in, v1.1.0+) — removes any express methods you list when the cart contains backorder items (out of stock with backorders enabled, or partially short). Useful for merchants who explicitly flag pre-order / made-to-order products and don't want them sold with express delivery.

Both rules raise a single dismissible checkout banner with merchant-customisable wording. Both respect the Drop-Ship Eligible exemption.

Stock-aware. Drop-ship aware. Hyvä compatible. Works with Magento Open Source and Adobe Commerce.

What's new

The version-by-version history lives in CHANGELOG.md. Highlights of the most recent releases:

• v1.4.0 — New per-product Force Standard Shipping Only flag. Tick it on the product edit page (under eTechFlow Shipping) to hard-disable next-day shipping for that product regardless of stock state. For bulky / hazmat / fragile / made-to-order items. Ships with a CLI verification command: bin/magento etechflow:nde:verify --sku=<sku> runs an end-to-end check that the observer + evaluator pipeline is wired correctly.
• v1.3.0 — Module status banner at the top of admin config (shows whether the module is actually active), PDP badge visibility toggle, drop-ship grid filter, inline tooltips on every field.
• v1.2.0 — Shipping method fields are now multi-select dropdowns auto-populated from your active shipping methods — merchants no longer need to know technical codes.
• v1.1.0 — Absorbed the deprecated ETechFlow_BackorderShippingRestrictor module's features as an opt-in "Backorder Express Restriction" toggle. The bundle is now 2 modules (NDE + BackorderEtaDisplay).

What it solves

Merchants who advertise next-day delivery hit the same problem from two directions:

Requirements

Installation

Option A — Composer (recommended)

composer require etechflow/module-next-day-eligibility:^1.1
bin/magento module:enable ETechFlow_NextDayEligibility
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush

Option B — Manual (from zip)

1. Unzip etechflow-module-next-day-eligibility-1.1.0.zip into:

   <magento-root>/app/code/ETechFlow/NextDayEligibility/
   

   The directory MUST be named ETechFlow (capital E, capital T, capital F) — case-sensitive on Linux servers.

2. Enable and set up:

   bin/magento module:enable ETechFlow_NextDayEligibility
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   

3. Verify:

   bin/magento module:status | grep NextDayEligibility
   

After install — quick setup

Open the admin and go to Stores → Configuration → eTechFlow → Next Day Eligibility.

Step 1 — License

License → License Key: paste the key from your purchase email and save.

Don't have a key yet? Dev/staging hosts are free. Any URL matching localhost, *.test, *.local, staging.*, dev.*, *.magento.cloud, ngrok tunnels, or RFC 1918 IPs runs at full features without a key. For non-standard dev domains, set License → Production Environment = No instead.

Step 2 — Enable the module

General Settings → Enable Module = Yes → save.

Step 3 — Pick your next-day shipping methods

General Settings → Next Day Shipping Methods is a multi-select dropdown. The list is auto-populated from your store's currently active shipping methods (the same list shown under Stores → Configuration → Sales → Shipping Methods). Tick the methods you want removed for ineligible carts — typically just your paid next-day or express options. Hold Ctrl/Cmd to select multiple. Save.

⚠️ Important — keep at least one fallback method unticked. Don't tick every option. The intended pattern is to tick only your paid express / next-day methods so a standard or free option always stays available for ineligible carts. If you accidentally select everything, a safety net returns the original rates and logs a warning to var/log/system.log to prevent a stuck checkout — but that's a guardrail, not a config strategy. See docs/USER_GUIDE.md "Configuration trap" for the typical UK setups.

That's the core feature done. Browse to a product detail page — you'll see the green "Next Day Eligible" / grey "Standard Delivery Only" badge under the price.

Step 4 — (optional) Enable Backorder Express Restriction

If you also want to block express shipping on backorder items:

Backorder Express Restriction:

• Set Restrict Express Methods on Backorder = Yes
• Express Methods to Restrict on Backorder — same multi-select pattern as the next-day field above, but stored independently. Tick whichever methods should disappear when a backorder item is in the cart. Can overlap with or differ from your next-day selection.
• Leave Skip Drop-Ship Products = Yes (default) so drop-ship products bypass this rule.

Step 5 — (optional) Customise the checkout banner

Checkout Notice:

• Show Notice at Checkout = Yes (default)
• Notice Style — warning (amber), info (blue), or error (red)
• Notice Title — bold heading, e.g. "Next day delivery unavailable"
• Notice Message — body copy, e.g. "One or more items in your cart is not eligible for next day delivery."

All four fields can be overridden per store view for multi-brand setups.

Step 6 — (optional) Hide or simplify the product-page badge

General Settings → Show Badge on Product Page:

• Both (default) — green "Next Day Eligible" + grey "Standard Delivery Only" badges
• Eligible only — show the green badge, hide the grey one (recommended if you don't want to draw negative attention to ineligible products)
• Never — no PDP badge at all; the shipping restriction at checkout still works

Per-product overrides (v1.4.0+)

Two checkboxes on the product edit page (under the eTechFlow Shipping attribute group) let you override the auto-calculation per product:

Precedence inside the eligibility evaluator:

1. Force Standard Shipping Only = Yes → always ineligible (merchant override wins)
2. Drop-Ship Eligible = Yes → always eligible
3. Otherwise: stock check (qty > 0 AND in stock → eligible)

Both flags work as Magento mass-action targets — see "Tips" below.

Tips for managing the catalogue

Bulk-flag drop-ship products. In Catalog → Products, filter the grid (now filterable by Drop-Ship Eligible — new in v1.3.0), tick the products, and use Actions → Update Attributes → Drop-Ship Eligible = Yes. Magento applies it to every selected product in one click.

Bulk-flag force-standard-only products. Same workflow with the new attribute: filter by Force Standard Shipping Only = No, narrow further (e.g. by category = "Furniture" or by weight), tick all, Actions → Update Attributes → Force Standard Shipping Only = Yes. Useful for one-pass classification of your bulky-item or hazmat catalog.

Bulk imports. If you're using a CSV import or custom script to load thousands of products, set $product->setData('_etechflow_skip_eligibility', true) before each save to bypass the per-product observer. Then batch-evaluate after the import completes via \ETechFlow\NextDayEligibility\Model\EligibilityEvaluator::evaluateById(...). See docs/USER_GUIDE.md "Bulk imports — the escape hatch" for the full pattern.

Module status banner. At the top of the NDE admin config section is a coloured banner showing whether the module is active, idle, or has a licence problem. Read it first if anything seems off — most "I configured it but nothing happens" cases are answered by that banner.
