You're running five jobs at once. You're also doing the books, chasing payments, playing file cabinet, and trying to remember what you told that client three weeks ago.

The late nights

Invoicing at midnight because the actual work takes all day. You know what "net 30" really means — it means 45 days of follow-up emails and awkward phone calls.

The scattered files

Contracts in email. Estimates in a notes app. Photos in a Dropbox folder the client can't find. Receipts in a shoebox. You've been meaning to fix this. That was six months ago.

Tax season dread

Every April is an archaeology project. Mileage you forgot to log. Expenses you can't remember. Income from three platforms that needs to be reconciled. It costs you hours — or it costs you money at the CPA.

None of this is why you went independent. You went independent to do the work — not to run a bureaucracy around it.

What if the whole back office just handled itself?

Booking confirmed. Contract signed. Invoice sent. Payment collected. Files delivered. Taxes tracked. seashellOS runs the business side so you can stay on the job site — or the keyboard, or the camera, or wherever you actually earn money.

Booking

Delivery

One platform. One login. The whole workflow.

Six tools you used to juggle. One that handles all of them.

Bookings & Contracts

Inquiry to signed contract in minutes.

A client finds you. They request a date. You send a quote. They sign the contract and pay the deposit — all before you look up from your last job. The whole sequence is automatic.

  • Google Calendar two-way sync
  • Smart contract builder with e-signatures
  • Auto-reminders so nothing falls through

Invoicing & Payments

Get paid faster. Keep every dollar.

Professional invoices with built-in payment links — schedule them to send on a set date or bill on a recurring cycle. ACH support, automatic payment reminders, and zero platform fees — what you earn, you keep.

  • Scheduled & recurring invoice automation
  • ACH + card payments
  • Zero platform transaction fees

Client Portal

Look like a studio. Work like a one-person shop.

Your clients get a portal with your logo, your colors, your domain. They can view invoices, sign documents, and access delivered files — all under your brand. They never see seashellOS.

  • Fully white-labeled — your brand everywhere
  • Client-facing file delivery and downloads
  • Custom domain support

Tasks Board

Every job. Every deadline. Nothing forgotten.

A clean board that shows everything in flight — jobs, tasks, follow-ups, and due dates. Not a bloated project manager with a learning curve. Just what you need to stay on top of six jobs at once.

  • All active jobs at a glance
  • Task lists and deadlines per project
  • Client notes and history attached

Mileage & Tax Tracking

Stop leaving money on the table at tax time.

Automatic mileage logging. Expense categorization. Quarterly tax estimates so you're never caught off guard. What used to cost you an evening and a CPA bill now costs you nothing.

  • Automatic mileage tracking on iOS
  • Deductible expense categorization
  • Quarterly estimated tax calculations

Shello — AI Admin

The assistant you couldn't afford to hire.

Shello knows your clients, your jobs, and your finances. Ask it to draft a follow-up email, estimate a project timeline, or pull last month's revenue — and it answers in seconds. Not a chatbot. A real business partner.

  • Drafts client messages in your voice
  • Answers questions about your own business
  • Gets smarter the more you use it

Six jobs in flight and you know exactly where every single one stands.

Your Work Board is a single view into everything active — not a Kanban system that takes an hour to set up, and not a spreadsheet you'll stop updating by Thursday. Just a clean, live view of your work.

  • Deadlines highlighted before they become problems
  • Every client note, file, and message attached to the job
  • iOS app — check in on any job from anywhere

April is just another month now.

Your phone logs mileage automatically. Expenses are categorized as you go. Quarterly estimates are calculated in real time so you know exactly what to set aside — no surprises, no scrambling, no archaeology project in March.

Your accountant gets organized numbers. You get your evenings back.

  • GPS mileage tracking on iOS — runs in the background
  • Snap a receipt, it's categorized instantly
  • Quarterly tax estimate updates as income comes in

Your AI business partner. Finally.

Every solo operator needs someone in their corner who knows the clients, remembers the numbers, and can draft that email at 9pm on a Tuesday. You couldn't afford to hire that person. Now you don't have to.

Shello lives inside seashellOS. It knows your clients, your active jobs, your finances, and your history. Not a generic chatbot — your business partner.

How much did I make in January?
January revenue was $7,840 across 9 jobs. Your highest-value job was the kitchen remodel for Roberts Renovation ($2,400). You have $960 still outstanding from Summit Electric — want me to send a reminder?
Yes, send the reminder. And draft a follow-up email for Maplewood Studios about their project.
Done — reminder sent to Summit Electric. Here's a draft for Maplewood Studios: "Hi [Name], just checking in on the Maplewood project. Happy to jump on a quick call this week if you have questions. Let me know what works."
