Welcome to the i-Source website. This site is for the sole use of TopSource and Topco employees and the suppliers with whom we do business. Our systems have recently changed - if your company was previously registered with i-source, you need take no action as your information has been transferred.

TopSource seeks to do business with high quality suppliers who provide excellent products and services for our customers. To register as a potential new supplier with TopSource, click here. There is no charge to register. You will be asked to provide detailed information about your company and products or services. It is important to accurately describe the type of business that you conduct to be considered for future sourcing events. Upon registering, you will not hear from us unless you are invited to a sourcing event such as a request for information (RFI), a request for proposal (RFP) or an online negotiation (reverse auction).
