You can update any supplier's contact info, lead time, delivery schedule, and pricing rules at any time. Changes take effect immediately and feed into the Order Planner the next time it recalculates.

Both Admins and Members can edit suppliers.

How many days from when you place an order to when it arrives. This is the most important field for the Order Planner — it's how Stash works backwards from your stockout date to figure out when to reorder.

Use the average. If a supplier varies between 3 and 7 days, set it to 5 and use the safety buffer to cover the worst case. See How Stash calculates when to reorder.

Extra days added to lead time as a cushion in case the supplier is late. Default: 1 day. Increase this for unreliable suppliers, decrease (or set to 0) for very reliable ones.

Example: lead time 5 days + safety buffer 2 days = Order Planner treats it as 7 days when calculating order dates.

Which days of the week this supplier actually delivers. If they only ship Monday–Friday and you'd otherwise be ordering on a Saturday, the Order Planner shifts the suggested order date to align.

Leave empty if they deliver any day.

The minimum dollar amount per order. If the Order Planner suggests an order below this amount, you'll see a warning so you can either add more items or wait. Useful for suppliers who charge fees or refuse orders below a threshold.

Used when sending purchase orders. (Sending POs by email isn't yet automated — you'll copy the PO details and email manually for now.) See Sending a purchase order to a supplier.

If you change a supplier's lead time today, existing draft and ordered POs aren't recalculated. The new lead time only affects future Order Planner suggestions.

When you create a PO, Stash takes a snapshot of the supplier's name, contact, and address at that moment. So if you later change the supplier's email, old POs still show the email that was active when you sent them — useful for audit and for resending.

Each item's cost price isn't tied to a specific supplier — it's stored on the item itself. If you buy the same item from two different suppliers at different prices, you can either update the cost when you swap suppliers, or use a workaround: create the item twice (one per supplier).
