Sideline

The professional standard.

Sideline is the premium sibling of Rostr, built for coaching businesses where this is the day job. A branded storefront, a team of coaches, a pipeline of leads, and books your accountant will accept on the first pass — for a flat 1.9% per booking. That’s the whole fee schedule. You just read it.

What it does

A storefront, not a side hustle

  • A branded storefront. Your name, your colors, your pages — with a real page editor, not a template with your logo taped to it.
  • A team dashboard. Multiple coaches, one business: shared calendars, per-coach availability, and one place to see the whole operation.
  • A leads pipeline. Every inquiry tracked from first message to first booking, so follow-up is a workflow instead of a guilty memory.
  • Packages and memberships. Session packs, recurring memberships, and team programs — priced once, sold on the storefront, reconciled automatically.
  • Payouts and statements. Reports an accountant will accept without a phone call. We consider that the highest bar in fintech.

Why it exists

When coaching stops being the side gig

A full-time coaching business has payroll-shaped problems: several coaches, hundreds of families, memberships that renew, and a bank account that has to survive an accountant’s attention. The marketplace platforms answer this with 10–20% fees and a storefront that belongs to them, not you. Generic booking tools answer it by not knowing what a season is.

Sideline runs on CoachCore, the same engine underneath Rostr, so the ledger discipline is identical — every session, credit, and refund in one running record. What changes is the posture: your brand out front, a team behind it, and one flat 1.9% per booking. No listing fees, no “pro” tier, no surprise line items. If our pricing page ever needs a scroll bar, we’ve failed.

Rostr or Sideline?

Same engine, two postures

Both run on CoachCore. The difference is which hat you’re wearing.

  • Rostr — the free ledger. For the coach with a day job: a booking page, prepaid packs, and a clean money record at a 0% platform fee.
  • Sideline — the storefront. For the coach whose day job this is: a branded business with a team, a pipeline, and statements — at a flat 1.9%.
