Pack-Based Selling Engine
Three pack types · Flexible pricing logic · Dual pieces/packs display · Quantity enforcement
Three Pack Types
Per-product pack type label shown in the storefront and order documents: Pack, Carton, or Pallet. Label is translatable via the CS-Cart language system.
Dual Price Type
Enter the product price either as per-piece or per-pack. The addon auto-converts: if selling in packs with piece-based pricing, the displayed pack price = stored price × items per pack.
Items Per Pack
Define how many individual units are in each pack (e.g. 12 pieces/carton). Supports decimal values (float) for weight-based products. Global default overridable per-product.
Storefront Display Modes
Control which tabs customers see: Pieces only, Packs only, or Both. Choose the default tab. First show: pieces or packs first.
Min / Max Pack Quantities
Set minimum and maximum order quantities in packs (decimal(12,3)). These auto-sync to CS-Cart's native min_qty and max_qty columns: min_qty = min_pack_qty × items_per_pack.
Quantity Step Control
Two modes: product_step (use the native CS-Cart qty_step) or product_amount_in_pack (quantity input increments by the full pack size). Prevents ordering partial packs.
Round Pack Amount
Automatically round the displayed pack quantity in the storefront (Y/N). Global or per-product override. Prevents fractional pack display when customers choose an amount not divisible by pack size.
Cart Display Mode
Three cart display options: number_positions (show counts per cart position), number_units (show unit count), or not_display (hide pack info). Controls what quantity label appears next to cart items.
Measurement Unit Display: When enabled, the storefront quantities are shown in the product's measurement unit (e.g. "24 kg" instead of "2 packs"). Integrates with the optional
ms_fractional_stock companion addon for full fractional quantity support.
B2B Trade Fields
8 dedicated product columns — turn every product page into a full trade specification sheet
Country of Origin
ISO 2-letter country code stored and expanded to the full country name on display (resolved via CS-Cart
country_descriptions). Appears in the B2B info tab on the product page.
MOQ (Minimum Order Qty)
Enforced automatically: setting MOQ higher than current min_qty raises CS-Cart's native min_qty (and ms_min_qty if fractional stock is active) so the cart refuses undersized orders.
Supply Capacity
Free-text field for production output (e.g. "10,000 units/month"). Displayed in the B2B tab so buyers can assess availability before bulk negotiations.
Lead Time
Free-text lead time description (e.g. "2–4 weeks after deposit"). Stored up to 100 characters. Shown prominently on the product page to set buyer expectations.
Incoterms
Select from the standard Incoterms 2020 list: EXW, FOB, CIF, CFR, DDP. Validated against a whitelist on save. Full label stored for display.
HS Code (Harmonized System)
6–10 digit international tariff classification code (HTSUS/HS). Up to 20 characters. Enables customs brokers and trade compliance engines to auto-classify shipments. Exportable via EXIM.
Sample Availability
Yes / No toggle indicating vendor can supply product samples. Displayed as a badge in the B2B info tab. Buyers filter for sample-ready products when evaluating suppliers.
Customization Support
Yes / No flag indicating whether the vendor accepts OEM/ODM customization requests (branding, packaging, sizing). Shown alongside sample availability as buyer decision signals.
Configuration
Three Settings Sections
Every setting has a sensible default and can be overridden at the product level. Admin sets the store-wide baseline; vendors tune individual products.
sale_type — pieces | packs (default: pieces)
price_type — pieces | packs (default: pieces)
amount_pack — items per pack (default: 1)
show_sale_types — pieces | packs | all
first_show_sale_type — pieces | packs
product_amount_changing_type — step | pack
display_in_product_measurement_units — Y/N
round_product_amount_in_storefront — Y/N
display_mode — positions | units | off
check_product_amount_by_units — Y/N

display_in_product_measurement_units — Y/N
round_product_amount_in_storefront — Y/N
display_mode — positions | units | off
check_product_amount_by_units — Y/N
Controls which storefront views show the pack postfix/label:
show_postfix_on_vendor_products — vendor listings
categories_view — category pages
products_on_sale — sale blocks
products_newest — new arrivals block
products_bestsellers — bestsellers block
companies_products — company page
product_features_view — features panel
wishlist_view — wishlists
products_search — search results
block_products — product blocks
show_postfix_on_vendor_products — vendor listings
categories_view — category pages
products_on_sale — sale blocks
products_newest — new arrivals block
products_bestsellers — bestsellers block
companies_products — company page
product_features_view — features panel
wishlist_view — wishlists
products_search — search results
block_products — product blocks
A third settings_info tab renders a custom Smarty template (
info.tpl) directly inside the addon settings page. Use it to display documentation, usage tips, or an interactive configuration guide — all in context where admins are configuring the addon.

Checkout
Cart, Checkout & Order Integration
Packaging data flows from the product page into the cart, order details, shipping calculation, and printed order documents.
Cart Pieces Tracking
When selling in packs, the exact pieces count is tracked in an auxiliary session variable (
ms_packaging_pieces_amount) alongside the pack count. This powers subtotal recalculation, stock validation, and order documents simultaneously.
Subtotal Recalculation
During
calculate_cart, the addon recalculates subtotals using price_by_piece × pieces_amount for precise billing. RFQ products (wk_rfquotation) are skipped entirely — their negotiated price is never overridden.
Stock Check by Units
Optional setting: validate stock in pieces rather than packs. Calculates how many complete packs fit within available stock and adjusts the allowed quantity accordingly, preventing overselling.
Order Details Row
Packaging data is serialized into
order_details.extra: sale_type, ms_amount_pack, show_sale_types, price_type, pieces_amount, price_by_piece, and ms_packaging_show_amount. All visible in admin order views and order history.
Order Document Variables
MsPackagingVariables injects packaging settings into CS-Cart's order document template engine. Invoices and packing slips can display pack sizes, price type, and unit amounts alongside the standard order data.
Inventory Delta
After purchase,
update_product_amount_pre hook adjusts the inventory delta to match actual pieces consumed. When display mode = all and pieces amount is known from session, it uses that exact count for stock reduction.
EXIM — Bulk Import / Export
All packaging and B2B fields are available in CS-Cart's standard product CSV export/import

Import uses both
process_get and convert_put callbacks registered in products.post.php EXIM schema. B2B fields pass through the same validation pipeline as the admin UI (incoterm whitelist check, MOQ → min_qty sync, country code truncation).
Bulk Operations & Addon Integrations
Apply packaging changes across multiple products at once, and maintain compatibility with RFQ and Fractional Stock addons.
Global Product Update
Extends CS-Cart's mass-update product tool. Admin can select sale_type (pieces/packs) and apply it to hundreds of products in one form submission via a single
UPDATE ... WHERE product_id IN (?n) query.
wk_rfquotation Guard
A dedicated
fn_ms_packaging_is_rfq_product() check protects three hooks: add_to_cart price, cart_product_data, and normalize_amount. RFQ-approved quotes (stored_price=Y, rfq_quantity_locked, or extra.wk_rfq) are never touched.
ms_fractional_stock Bridge
When the companion
ms_fractional_stock addon is active (but does not conflict — conflict is registered), the product info function switches to the fractional path: allow_fractional_amount, ms_unit_measure, ms_step_qty, ms_min_qty, and ms_max_qty are all resolved via the fractional addon's own helper functions.
Static Request Cache
fn_ms_packaging_get_product_base_data() caches all packaging columns per product in a static PHP array for the duration of the request. Eliminates the N+1 query problem. Cache is invalidated by fn_ms_packaging_clear_product_cache() after any UPDATE.
Product Tabs (Backend)
Two dedicated product edit tabs injected via Smarty hooks:
ms_fractions_stock_and_packaging_tab.tpl (pack configuration) and ms_b2b_fields_tab.tpl (B2B info fields). Both tabs appear for admin and vendor product editing.
Order Items Row Override
Admin order detail page: the order product row is overridden (
items_list_row.override.tpl) to display the pack-quantity summary (pieces vs packs), price per piece, and the sale type label instead of the raw CS-Cart amount field.
