The easiest way to collect vendor fees online is to use a platform that connects directly to Stripe so payments go straight to your account without manual invoicing or follow-up.
Events Near Me has Stripe-powered payments built in. When a vendor applies to your market, you can collect booth fees or application fees right through the platform. The free plan charges a 3% processing fee per transaction. If your market does enough volume, the Growth plan drops that to 1% for $30 a month, which usually pays for itself.
