Sound familiar?
"Paying $49–$399 for a card reader you use twice a month."
Hardware costs add up fast — and most readers sit in a drawer between markets.
"I'm paying for 6 different apps that don't talk to each other."
POS here, accounting there, email marketing somewhere else. Every tool is a silo.
"I spend Sunday nights doing bookkeeping instead of being with my family."
Manual data entry, receipt hunting, and reconciliation steal hours you don't have.
"My accountant asks for receipts I threw away three months ago."
Without document capture, tax time means scrambling through shoeboxes and email.
"I need to send an invoice but I'm at a job site, not at my desk."
Your business doesn't stop when you leave the office. Your tools shouldn't either.
"Managing 3 employees shouldn't require this many spreadsheets."
Small teams deserve real HR — scheduling, time tracking, and payroll without enterprise pricing.
Not retail? Muin runs service businesses too.

One platform for the SMB stack
Most small businesses cobble together separate tools for sales, accounting, marketing, invoicing, and employee management. Data lives in silos. You re-enter the same information everywhere. Muin builds POS, invoicing, CRM, forms, and HR; integrates with Gusto for payroll and QuickBooks/Xero for accounting — all wired into one set of customer and product records.
Before Muin
- Square or Clover for POS ($49–$849 hardware + monthly fees)
- QuickBooks for accounting ($30–$200/mo)
- Mailchimp for email marketing ($13–$350/mo)
- Google Forms for customer intake (free but disconnected)
- Excel for inventory tracking
- DocuSign for contracts ($15–$65/mo)
- Gusto for payroll ($40–$150/mo)
- WhatsApp Business for customer chat (manual, no tracking)
8 disconnected tools. $150–$800+/mo. No single source of truth.

Maya (illustrative scenario), Farmers Market Vendor
"You started this business to make something beautiful, not to fight with spreadsheets."
Saturday morning at the market: customers tap their phones to pay — no card reader to charge or forget at home. Between sales, Maya snaps a photo of a supply receipt and AI files it automatically. Her email list gets a "new flavors this week" blast she wrote on the drive over. At the end of the day, she asks Muin: "How did today compare to last Saturday?" The answer comes in seconds. Sunday, she checks cash flow from the couch. Monday, her accountant logs in and everything is already categorized. Tax season is already handled.
