I wish to have a complete Local Purchasing Procedure for all type of items. I am doing a new policy for my company . So, is there any good procedure for all items available?
The policy will depend largely on the need and where you are at present.
For smallish and consumables etc you can rank the items according to Fit for the purpose, Quality vs specks , availability , service and price.
This can be equated and ranked to an total economical cost. The resulting cost per unit of time. What is the best buying cheaper parts more frequently or an expensive part less often. Why stop a process to replace a minor cost item. The production loss may exceed the savings for a cheaper part.
This will result in products above and below a line.
A data base like this will never stay static and the info should be updated regularly.
Hope this will be helpful.

In addition to Hendrik's good quality advice, also keep in mind any cost accounting procedures your company has/needs for tracking purposes. Do you use company credit cards, reimbursement with receipts, or some combination of these? Who will be authorized to approve/make local purchases? Will you prefer single/few sources, or whomever has the item on sale cheap this week? Don't forget to specify an MSDS for any product that should have one, in particular anything with hazardous properties.
Many variables to consider; another is registering as a member here - there are far too many 'guests' to keep track of already... Best wishes.
