Purchase order (PO) functionality allows for purchasing materials and products from suppliers, increasing the stock inventory levels. If you want to purchase manufacturing service of products from a contractor and track required ingredients, then create an Outsourced Purchase order instead.

In Katana, you can add all the required items from a supplier to a PO with only a few clicks. If other materials are missing from this same supplier, a notification will appear on the PO card as a reminder The required amount for each material is based on the Missing/Excess quantity displayed on the Stock screen.

If you created multiple Locations with the Buy functionality enabled, you can choose which Location the items will be received.

A PO can be created either through the global "+" sign, from a quick-add button on a Manufacturing order (MO), or on the Stock screen.

On a MO or in the Stock screen, click on the + Buy button at the end of the line for a specific item to create a PO for the required item. This is a quick way to create a PO for materials that are required by a MO, for products purchased for resale, or to re-establish optimal stock levels. In the quick-add window, you can choose to "Add other missing items from the same supplier to the purchase order".

Each PO has a delivery status that can be manually changed. Statuses trigger changes in the inventory and help to monitor and manage purchasing activities.

*Supplier
Name of the supplier for the material or product being purchased. If you add a line item to the PO before selecting a supplier, Katana will automatically fill in the Supplier field based on the default supplier you have set for the added item. This field can be edited manually at any time.

*Purchase order #
Unique identifier for the PO. This is auto-generated but can be edited manually if needed. Example: PO-1, PO-2.

The PO card does not include the address info of your company or the shipping address of a specific Location, but address info is displayed if the PO is printed.

It's easy in Katana to create a single PO for all items required from a selected supplier.

When you add a Supplier to a PO, Katana will check the stock status for all materials and products purchased from this supplier (based on the Default Supplier value defined on the item card).

If there are items with negative Missing/Excess values in "Stock" that are not yet included in the PO, Katana will display a notification at the bottom of the page.

Click Add them... to open a list of all missing items from this supplier and you can choose to add them to the PO individually or add all with a single click.

New items will be added and quantities for existing items will be updated on the PO to reflect the missing quantities in your stock.

You can add comments to a PO such as specific instructions to purchasing personnel, purchasing details, reference numbers, references to the location of relevant files, etc.
