You Wear Every Hat.
You Need a Second Brain.
Stop using Excel for inventory and Gmail for invoices. GrexOS is the operating system for self-employed professionals who need to stay organized without hiring an accountant.
The Solopreneur Struggle
Spreadsheet Hell
Your inventory lives in Excel. Your expenses live in another sheet. Nothing talks to each other. Tax season is a nightmare.
The "App Tax"
You're paying for QuickBooks ($30), a scheduling app ($25), and a CRM ($40). That's $95/month just to keep your head above water.
Looking Amateur
Sending invoices as Word docs makes you look unprofessional. Clients hesitate to pay because your systems feel janky.
The GrexOS Way
Automate Your Sales Cycle
Quotes lets you create professional estimates in 2 minutes. When the client says "yes," click one button to convert it into an invoice. Invoices then sends automated payment reminders so you don't have to chase people.
- Generate branded PDFs that look professional
- Track quote status (sent, viewed, accepted)
- Convert quotes to invoices with one click
- Get paid 2x faster with automated reminders
Protect Your Profits
Excel can't tell you when stock is low or calculate your margins automatically. Inventory tracks buy/sell prices, monitors profit margins, and alerts you before you run out of your best-selling items.
- Track cost price vs. selling price per item
- Get alerts when stock hits reorder point
- See your total asset value at a glance
- Link products to vendors for easy reordering
The Digital Filing Cabinet
Stop digging through email threads to find that contract you signed last year. Customer CRM stores every client document, interaction log, and project note in one secure, searchable vault.
- Upload contracts, IDs, certifications per client
- Log every phone call and meeting with timestamps
- Tag clients by project type or status
- Keep extended notes for client history
