Most service businesses juggle 5+ disconnected tools, pay hidden platform fees, and spend more time on admin than on actual client work.
CRM, invoicing, project management, file sharing, scheduling — all disconnected. Data lives in silos.
Platform fees on top of processing fees. At $10k/month in revenue, you lose $200+ to your own tools.
Jumping between apps to find a client's info, check a payment, or send a follow-up. Every day.
"Powered by OtherBrand" on your invoices. Your clients see your vendor's brand, not yours.
That's over $1,200/year back in your pocket — and zero platform fees on every payment.

Your brand, not ours. Clients log into your portal at your domain with your logo and colors. They never know seashellOS exists.

Everything you need to know about seashellOS.
seashellOS charges absolutely nothing on top of your client payments. You only pay your payment processor's standard rate (card processing is typically around 2.9% + 30¢, though it varies by processor). Some platforms take more: Bonsai adds a 1% markup on every payment, and HoneyBook requires payments to run through its own in-house processing — their rate, their terms, no choice of processor. With seashellOS you connect your own Stripe, Square, or Helcim account, and everything beyond the standard processing fee stays with you.
