Reminders sent 3 days and 1 day before the asset deadline. Overdue alert fires automatically if they miss it.
Is SponsorCal right for you?
Not a marketplace. You bring your sponsors, set your rates, and keep 95%. Here's who this is built for.
This is for you if
- You're getting sponsor inquiries and need a better system than 'email me'
- You'd rather approve than chase
- You want payment before you deliver
- Your time is more valuable than custom workflows
This is NOT for you if
- You're looking for a marketplace to find sponsors
- You prefer to send your own invoices
- You want net-30 or post-publication payment terms
95%
You keep
5% platform fee
+ Stripe processing fees (2.9% + 30¢)
