Solid# vs Square

Square Processes Payments.
Solid# Runs the Business.

Square started as a card reader. They added software — but it's bolted on, not native. Solid# is AI-first infrastructure where payments are one capability of many.

Square

Square is a payment processing company that expanded into POS, scheduling, online store, and payroll. Jack of all trades, master of payments. Each "Square" product is a separate app with separate billing — Square Appointments, Square Online, Square Marketing, Square Payroll.

Solid#

Solid# is one unified AI platform. Payments, POS, scheduling, CRM, marketing, website, voice AI — all connected, all powered by 116 agents. When Sarah books an appointment, it's already in the CRM, the customer gets a confirmation via SMS, and the invoice is auto-generated. No app switching.

Why People Switch
From Square

App Sprawl

Square Appointments. Square Online. Square Marketing. Square Payroll. Square Invoices. Five separate apps that barely talk to each other. Solid# is one platform.

No AI at All

Square doesn't answer calls. Doesn't follow up with leads. Doesn't run marketing campaigns. Doesn't optimize pricing. You're still doing everything manually.

Transaction Fee Trap

Square's "free" POS charges 2.6% + $0.10 per transaction. On $300K in annual sales, that's $7,800+ in fees. Solid# connects to your processor — bring competitive rates.
