Dear Khun Molly
All the purchases must meet the specs (including quantity and requirements) specified by our consultants.
In fact, it should be the consultants who will provide us with the specifications.
We then source for suppliers based on the specifications provided (in writing) by the consultants.
After we have received the quotations, we then send them to the consultants for comments and evaluation.
After we have received the consultants comments and evaluations, Management should then make a recommendation to me for approval.
Once approve, we can then issue PO.
The main contractor will provide us with a written request for deliver. Pathom's delivery requests (date, quantity, etc) are to be endorsed by the consultants.
Management need to comply with and enforce the above.
Hope the above is clear enough to guide Management
