What SponsorDesk actually does.

Drag deals from inbound to negotiating to live to paid. Every brand's status is one glance away — no more hunting through email threads to remember where a conversation left off.

Not sure what to charge? The free rate calculator benchmarks a sponsored post against platform, audience size, and niche. One deal priced even $20 higher because you had a real number to quote covers more than a year of the $9/mo founder plan. The math isn't close.

A daily job checks every unpaid invoice and sends a reminder at exactly 3, 7, and 14 days overdue — no one has to remember to chase anything. This is the single biggest source of recovered revenue on a solo pipeline: brands don't usually refuse to pay, they just go quiet, and quiet is what reminders fix.

Set net payment days, a late fee (flat or percent), and a grace period per deal — before an invoice even exists. Write your own terms note or generate one from the numbers you set.

Once terms are set, they're not just internal bookkeeping: the brand sees them on every reminder email, so "that wasn't the deal" stops being a valid objection when a payment's late.

After 14 days overdue, a formal demand letter becomes available — one click sends it, referencing the original invoice, days overdue, and any late fee. It's a different email than a reminder on purpose: firmer tone, for when a nudge hasn't worked.
