Imagine a marketplace where you stay in control of your business - and your customer journey.
Customers can discover your products and the business behind them, rather than seeing you as just another product listing. A marketplace that doesn't process or control your transactions and doesn't take commission from your sales. You continue to take payments your way — through your own website, card payments, payment links or bank transfer. No percentage taken from every sale. Just a monthly fee based on the scale of your business.
And for our first 300 Activated Sellers, that monthly fee is FREE for 12 months.
Customers discover your products on MC999 and complete their purchase directly with you, helping you retain control of the customer journey. Sellers using Shopify, BigCommerce or Shopline can connect their online store, allowing customers to click through and complete their purchase on their existing website.
Join MC999 at the beginning and help shape a marketplace designed with independent online businesses in mind.
We're inviting our first group of sellers to build their presence early, share feedback and help us develop MC999 around the needs of real online business. Of course we know what works and what doesn't for our business but every business is different.
And there's an extra benefit to starting early:
No monthly subscription fee for your first year once your seller account and catalogue are activated.
We help bring buyers and independent sellers together, but MC999 doesn't process or control the payment transaction.
If you connect an integrated store, like Shopify,
BigCommerce or Shopline, customers discover your products on MC999 and continue through to payment on your website.
If you list your products directly on MC999, you arrange payment with the customer using your own preferred payment method. Either way, you remain in control of the sale and your customer relationship.
Every sale should reward your hard work—not disappear in fees. With no commission on your sales, you keep more of what you earn and invest it back into growing your business.

Why rely on one marketplace? Build your presence on another platform, showcase your products in more places and create new opportunities for future growth with MC999.
Your business deserves flexibility and control. Build your brand, grow your customer base and sell on your terms with a marketplace designed to support independent businesses.
Your business deserves transparency. We believe in straightforward policies, fair decisions and open communication—giving you confidence to focus on growing your business, not worrying about unexpected changes.

We’re looking for established UK online sellers who want to grow their presence without giving up control of how they run their business.
MC999 could be a great fit if you:
Already sell products online
Have an active online store or established marketplace presence
Have an existing product catalogue
Are looking for additional ways for customers to discover your business
Want to retain control of your sales, payments and customer relationships
Are happy to share feedback as one of our early sellers
Interested, but not ready to set up your seller account yet? Stay in the loop and we'll keep you updated as MC999 develops, including new seller opportunities, features and marketplace news.
