If you serve clients, seashellOS was built for you.
We started with creative studios. But the platform was always built for anyone who runs a service business — anyone who books clients, sends invoices, signs contracts, and wants to look professional doing it.
And countless more. If you serve clients and want to get paid — you're home.
You're great at what you do. The tools you're using to run the business are working against you.
Chasing payments is a part-time job
You send the invoice. Then you wait. Then you send a follow-up. Then another. Meanwhile, you're doing the actual work — which means the business side always happens at night, on weekends, in stolen minutes between clients.
Client communication is everywhere
Text here. Email there. Instagram DM. Facebook message. A voicemail you haven't returned. You're not providing a poor experience intentionally — you just have no central place to manage it all.
You're paying for five apps to do one job
Scheduling tool. Invoice software. Document signer. File sharing. CRM. They don't talk to each other, they don't look the same, and every one of them charges you monthly to exist. That's before the 2.9% platform fee on every transaction.
You can't afford big-company tools — but you need big-company results
The software built for small businesses is cheap because it's cheap. Generic. Template-driven. No white-label. No AI. No financial intelligence. You look like every other small business — not like the professional operation you actually run.
You opened a bakery to bake. You started a salon to do great work. You became a consultant because you're brilliant at it. The admin shouldn't be eating you alive.
One platform. Your entire business.
seashellOS replaces 5-10 disconnected apps with a single, intelligent platform. Client bookings, contracts, invoices, file delivery, messaging, financial tracking, and an AI assistant who knows your business inside out. All under your brand. All in one login.
platform transaction fees. Every dollar you earn stays yours.
login for your entire business operation. Not 10 apps.
per month to start. Less than two coffees. Real results.
The entire client workflow. One platform. Totally automatic.
Everything you need. Nothing you don't.

White Label Client Portal
Your brand. Your portal. Your clients.

Financial Dashboard
See your money in real time. Actually understand it.

- Real-time bank data via Plaid
- Cash flow and revenue dashboards

Shello AI
Your AI business partner. Finally.
Shello knows your clients, your finances, and your entire history. Ask it to draft a follow-up email, pull last month's revenue, or remind a client about their unpaid invoice. It handles the busywork. You focus on the actual work.
- Drafts client messages in your voice
- Knows your business data — not generic AI
- Handles follow-ups, reminders, and admin
Zero Platform Fees
Zero platform fees. You keep what you earn.
Platform fees seem small until you do the math. A business collecting $5,000/month in client payments loses $150-$170 every single month to platform fees — $1,800-$2,000 a year, just for the privilege of using their software.
seashellOS charges zero. You pay for the platform. You keep what you earn. That's how it should work.
- Zero transaction fees on all tiers — Free through Team
- Your processor handles payments at its standard rates (not ours)
- ACH available to reduce even card processing costs
If you collect $5,000/month
Standard processing fees still apply. seashellOS adds zero on top.
Shello
The assistant every small business deserves. Finally affordable.
Every great business owner has a great person behind the scenes — someone who knows the clients, handles the follow-ups, drafts the emails, and keeps the books organized. You couldn't afford to hire that person. Shello is that person.
Shello lives inside seashellOS. It knows your clients, your active projects, your finances, and your history. Not a generic chatbot you have to explain everything to. Your actual business partner.
- Drafts client messages that sound like you
- Sends payment reminders automatically
- Answers questions about your revenue, clients, and jobs
- Gets smarter the more you use it
