It is necessary that you know exactly what your need is and what you want to procure to meet that need. Do not fall for materials/equipment that you do not need in the near future. Get estimates verbally, through the internet, yellow pages, personal inquiries in the market, and through contacts in other industries. Prepare a robust proposal for management along with the estimates you collected through your efforts. After approval, ask for technical bids from manufacturers, stockists, and dealers. Compare the technical details of the equipment and shortlist the ones that suit your purpose. Now ask for quotations from the manufacturers, stockists, and dealers of competing companies to get the best deal. Always negotiate for a better price and after-sales service. Avoid fly-by-night companies. Deal with financially sound and well-established outfits.
