Visit us at The Foundry and speak with a member of our team to discuss the options available to you. If a space is available you can move in straight away! If there is not a space available right away, you can opt to be placed on our vendor waiting list or look at an alternative option such as one of our bespoke display cases.
No problem! We encourage prospective vendors to move in and start selling as soon as possible. Pro rated booth rent for the remaining period until the first of the following month will be due at contract signing.
Yes. We have a standard form contract which outlines the terms of your rental agreement.
We charge a commission of 10% on all sales.
No! Here at The Foundry we believe that you should discover the best selling environment for you. We have a six month initial term. Following this, we require just a thirty day written notice if you wish to change or terminate your rental agreement.

For the convenience of all our vendors, we automatically process your rent payment from your previous month sales. If you do not have sufficient sales to cover the rent due we will notify you that payment is required. We recommend that all vendors take advantage of our vendor sales tracking system, QuailHQ for $5.00 per month.
We work in partnership with QuailHQ to provide online access to sales data 24 hours a day, 7 days a week. QuailHQ is available online and as an app for ios and android.
We recommend that all vendors take advantage of our vendor sales tracking system, QuailHQ for $5.00 per month.
Yes! We operate Social Media accounts on various platforms.
