Become a Verified Supplier & join our Edinburgh and Glasgow supplier directory.
We are taking the work we do in “procurement” and building a directory of fantastic suppliers who cover a huge range of B2B overhead services.
Access qualified buyers, not just leads.
Stop wasting resources on unpredictable lead generation.
Our CALM Supplier Directory is only open to our Verified Suppliers and is an opportunity to build enhanced relationships with potential customers.
Our Verified Supplier Directory provides our CALM Supply Chain members with easy access to 140+ overhead services, ensuring they look to you first.
We’re rolling out our BRAND NEW regional directory across the UK from September 2025.
The CALM Supplier Mark
The CALM Supplier mark provides independent accreditation for SMEs.
Created specifically for businesses like yours – innovative, ambitious companies who support other UK businesses.
Designed for UK SMEs who want to make a statement about their honesty, commitment to supporting their customer and open and honest communications.
Mark yourself out from the crowd!
Our fees depend on your business size:
Micro for 1 employee
Small business for 2-10 employees
Medium business for 11-50 employees
Large business for 50+ employees
Not only will you gain access to all the fantastic benefits of our CALM Verified Supplier Certification but you’ll also gain a place on our Preferred Supplier list.
Our aim is to provide an independent verification of your business which you can use in your marketing but also create a powerful list of Preferred Suppliers so we can refer you to customers as they need you.
You can find the questions you will need to answer during the application here (sorry about the tiny font, who know’s what’s happening with the settings at the moment) and we follow this up with a company credit check, review of your standard terms of business & insurances.
We’re looking for suppliers who are open, transparent and supportive of their customers. Check out our Supplier Code of Conduct.
