Configuration

Open Add-ons → Manage add-ons → Purchase Orders & Suppliers → Settings. On CS-Cart Ultimate, select a storefront to give it its own number format, delivery address and storefront note.

General

Setting	Default	What it does
Enable purchase orders	On	Switches the add-on on or off. When off, nothing is shown on the storefront.

Numbering

Setting	Default	What it does
Purchase order number format	PO-{YYYY}-{N}	Tokens: {YYYY} year, {YY} short year, {MM} month, {DD} day, {N} running number (required), {VENDOR} vendor or storefront ID.
Digits of the running number	5	{N} is padded with zeros (1–10 digits).
Restart numbering every year	On	The running number starts at 1 on 1 January. Keep {YYYY} or {YY} in the format.

Numbers are given when a purchase order is saved for the first time and are never reused (a cancelled purchase order keeps its number). Each storefront (Ultimate) and each vendor (Multi-Vendor) has its own series; add {VENDOR} to the format if numbers must be unique across the whole marketplace.

Stock and reorder suggestions

Setting	Default	What it does
Default reorder point	5	A product is suggested when its stock plus the quantity on order is at or below this number. Products can have their own value.
Default target stock	20	Suggestions fill the stock up to this level. Products can have their own value.

Storefront

Setting	Default	What it does
Show expected delivery on product pages	Off	Out-of-stock products show “Back in stock expected on …” when an open purchase order with an expected date contains them.
Days added to the expected date	2	Safety margin added to the supplier’s date before customers see it.

Vendors manage purchase orders	On	Vendors manage their own suppliers and purchase orders for their own products in the vendor panel.

License

The License section shows the license status, the licensed domain and Check now. Enter your Kavio Labs license key there, or the CS-Cart Marketplace license number in Add-ons > Manage add-ons.

What switched off means: no new purchase orders can be created or sent and the reorder suggestions and storefront delivery notes are paused; existing purchase orders stay viewable, printable and exportable, and goods can still be received into stock, so your stock levels stay correct.
