Free Apple-To-Apples Cost Comparison

Before joining CPG, we’ll deliver a no-cost, no-obligation, “Apples to Apples” comparison of products you purchase and potential savings. Every health center and nonprofit is different, so your report will be tailored to your organization’s experience and current costs. Subsequently, you can decide if you’re ready to commit to a GPO focused on saving in every possible way.

First, we take a representative sample of your organization’s most recent invoices. Then, in consultation with our vendors, we conduct a two-part analysis and determine where cost savings are attainable. Gathering invoices can be a hassle, but we’ve found that they’re integral to providing an accurate cost-comparison and savings report. As a result, you will have a custom detailed report showing where you can save money the most.

We welcome and are always happy to accept invoices for analysis!
