Purchase Order Implementation

Business Workflow

The Procurement workflow moves kanban cards through the ordering and receiving lifecycle:

1. Cards for an item are listed from the Items view.
2. A card is added to the procurement queue by sending it the ACCEPTED signal, which transitions it to the REQUESTED state.
3. The user reviews the procurement queue: a list of all cards in REQUESTED state, grouped by Vendor and Order Method.
4. The user selects cards and orders them:
   • For online orders: the item URL for the vendor opens.
   • For other methods (e-mail, phone, etc.): a side panel displays message text for the user to send manually.
5. The Order action sends a start_processing signal, transitioning the card to IN_PROCESS.
6. The Receiving view shows all IN_PROCESS cards. Receiving a card sends the receive signal, transitioning it to FULFILLED.

Kanban Card State Mapping
