Optional Step 6: To bring our customers and suppliers closer together, we’re launching a regional Supplier Directory of Verified Suppliers who provide a range of B2B services. You’ll be invited to list on our directory if we need your services*.

The entire process typically takes 2-3 weeks, after which you'll hold the CALM Supplier Verification certification, that immediately elevates your business.

*Note : as we roll out the Supplier Directory to each region, we will invite suppliers who we think are best suited to our customers. We look for a mix of different businesses, so selection could be based on niche services, business size, sector experience and a number of other factors. Please don’t be disappointed if we don’t currently have space for your business in the directory.
