The below one is a general guide, while herein this website we have provided specific tips for all different types of materials. But in all cases, the following tips shall always be useful.
A) Personnel Requirements:
Need or Desire:
One has to clearly understand whether anything which he or she wants to buy is his or her genuine need or it is a mere desire. Desires have no end, and infinite desires will keep you working whole throughout your life for fulfilling desires.
E.g.: To feed children with nutritious food is his need but when the child wants to eat chocolate, it is his desire.
Why you need that particular material:
Once you convinced yourself that a particular material is your need, you must know and find out the object of buying that material i.e. why? You must understand its uses and under which circumstance you are going to use it and how does it meet your need or how it would be useful to you.
Remember the famous saying “when you buy “useless materials”, a day will come in your life, when you will be compelled to sell useful materials”.
What actually you want to buy?
Having found out need and object of buying alone is not sufficient. You must also clearly know what do you want to buy.
It happens when you buy out of your desire. You may say, you want to buy a house or want to buy a vehicle or an artificial wood. But you must understand what type of home you want to buy, where and so on. Similarly when you to buy a vehicle, decide whether you want a 2 wheeler or a 4 wheeler and of which type etc. Similarly in case of artificial wood, whether you want to buy a ply, laminate, veneer or MDF etc.
Quality and specification you are looking for w.r.t. your need, and ascertain whether you really need all these features:
Based on your need you should define the specifications and quality of materials that you want to buy. Suppose you want to buy cement then you must know whether you want to buy OPC or PPC. Similarly if you want to buy reinforcement steel decide you want buy mild steel or Tor steel and again its grade like Fe415 or Fe500 or Fe500D.
When you identify the product make sure it is a right product for you i.e. it should not possesses too many more properties or features than you even need. Similarly it should also satisfy the basic minimum needs. Hence there should be a balance between properties and cost.
Warranty/ Guarantee and study of product literature:
While buying anything, you should also study the product literature and technical specification, which may be either described on the packaging or may be available on the website of the manufacturers. Many times what the sales persons represent to you and what is actual written by manufacturer in the literature and what is understood by you are totally different. Ultimately what is written on the product literature will be final and prevail. So try to understand all the properties, chemical composition, cautions of use, advise for use etc., written by the manufacturer. Also study the terms and conditions of warranty, guarantee etc.
You must fix the budget for each and every individual item. When you are buying so many items at a time budget is to be viewed in totality as compared to your overall total budget. Please keep in mind that there are always better materials available in the world and it is your budget which will be a ceiling for your selection. In fact have a habit of not even looking at things which are beyond your budget, unless you can control yourself.
Quantity you want to buy:
You should also estimate the right quantity that you want to buy. Knowledge of quantity required will put you in a right position while bargaining. E.g. Quantity of sand or cement you want to buy.
Where is it available, from where to buy?
You must search for the right seller and their location. You should also find out whether it is directly available from the manufacturers or manufacturer’s sales depot, distributors, whole sellers or retailers etc. The price at which you buy, will definitely depend from whom do you buy.
Cost of transport/Taxes:
While buying a material always add to your budget, the cost of transportation, taxes and duties including cost of loading and unloading at site which are mostly unforgotten.
C) Quality & Brand:

Need of Spares:
Whether it needs spare etc. periodically/regularly over a period of time and if so, its cost
Repairs that may be needed every year:
If you are buying a big budget product, please make sure what is the cost of operations and also cost of normal maintenance. You should also estimate the cost of periodical repairs and maintenance that may be needed.
Annual maintenance Contract:
a) Whether the seller or manufacture provides AMC (Annual Maintenance contract) and if so, what is its price? Check if you don’t buy the AMC, will it be still workable?
b) Sometimes the cost of AMC to be paid annually is much higher as compared to the cost of one time purchase. Further if you don’t buy AMC, you lose all the rights from product updations as well as benefits available under the guarantee or warranty.
c) Cost of replacement of major parts, after some years as in case of membrane of RO Water treatment plants.
E) Life of Material:
