The list
Filters: name, contact, email, phone, status and created dates. Columns: name, contact, email, payment terms, status. Row actions: View, Edit and Deactivate / Activate (no confirmation). You need inventory.suppliers and a plan that includes purchase orders.
Fields
Name (required), contact, email (needed to send a purchase order), phone, currency, payment terms, tax ID, address and note. On Farsi sites a phone must be an Iranian mobile (starts with 09, 11 digits). There is no duplicate check. Clearing an optional field and saving does not clear it on the server, so fields cannot be blanked.
No delete
Suppliers are deactivated, not deleted. An inactive supplier disappears from the purchase-order picker; existing orders keep the name and email copied at creation. Deactivating is not blocked by open orders or by items that name the supplier as default, and reorder drafts and sending do not check that the supplier is active.
The supplier page
Total Spend (the totals of received POs only, adding amounts across currencies), POs Received, Total POs (all statuses) and a table of the supplier's orders.
Default supplier and reorder
An item's Default Supplier decides which supplier a reorder draft is made for. An item without one still appears on the Reorder page and in low-stock alerts, but its row cannot be ticked, so no draft is produced.
