If you need spares for your business then you might tend to just rely on the one supplier. If you have a good relationship with them, trust them and get a good price and great value for money, then it is not surprising that you are sticking with them. However, many businesses are not that happy with their suppliers but still stick with them because they do not know of any alternative. It is well worth breaking this habit and taking a bit of time to do the necessary research so that you can find out whether there are companies that will be better suited for you.
For example, imagine that you need a conveyor spares supplier. You can look online and see what companies come up. However, you will have no way of knowing whether you should trust these companies or not. It might be that you are so desperate to try someone new that you will go for the top one on the list, say SL plastics and just hope that they will suit you. However, this is risky. If you are having a really bad experience, it is unlikely that a company you choose will be even worse, but you might not pick one that is the best for you.
Take a bit more time and look into them in a bit more detail. Firstly, explore their website so that you can find out what they are like. There might be details about the company and their history as well as the types of products they have and their prices. It can be worth contacting them as well to get any questions answered as this will help you to find out how quick they are to deal with queries and how good their answers are as well as how polite and friendly their customer service staff seem to be. You should also see whether you can find any reviews of them. Finding out what other customers think can be really useful. You may find reviews online; you might know other business owners that you can ask and see whether they would recommend them.
It is worth taking the time to do this research as you will be able to find out more about the company. You will be able to see whether they are the sort of company that you would like to deal with and whether you think that they will be able to suit your needs.
