OnlineInvoiceMaker vs Square Invoices: Free Invoice Maker Comparison
Square Invoices is part of the Square ecosystem, offering invoicing tightly integrated with Square’s payment processing and POS hardware. It is popular with US-based businesses that already use Square for in-person payments and want a unified platform for card transactions. However, Square charges 2.6% plus $0.10 per card transaction on every invoice payment, the Plus plan costs $20 per month for advanced features, and its template options are limited compared to dedicated invoicing tools. OnlineInvoiceMaker takes a different approach: completely free invoicing with no transaction fees, no account required, nine professional templates, built-in GST support with CGST, SGST, and IGST fields, and thermal printer compatibility for retail and point-of-sale environments. This comparison helps you decide which tool fits your business needs based on cost, features, and flexibility.

Why Choose OnlineInvoiceMaker Over Square Invoices
Zero Transaction Fees
Square charges 2.6% plus $0.10 on every card payment processed through an invoice. On a $1,000 invoice, that is $26.10 in fees. OnlineInvoiceMaker is completely free with zero transaction fees, zero processing charges, and no hidden costs regardless of invoice volume.
Professional Template Library
Choose from nine distinct invoice templates including Classic, Modern, Corporate, Creative, Executive, Gradient, Minimal, Professional, and Tax Invoice. Each template offers full customization of layout, colors, and branding. Square limits advanced templates to its paid Plus plan.
Built-in GST Compliance
OnlineInvoiceMaker includes native GST support with dedicated CGST, SGST, and IGST fields plus HSN/SAC codes. Square Invoices does not support Indian GST requirements, making it unsuitable for businesses in India and other countries with similar tax structures.
Standard Thermal Printing
OnlineInvoiceMaker supports standard 58mm and 80mm thermal receipt printers used worldwide. Square locks you into their proprietary hardware ecosystem. If you already own thermal printers or want hardware flexibility, OnlineInvoiceMaker works with your existing setup.
No Vendor Lock-in
Square Invoices works best within the Square ecosystem. If you switch payment processors, you lose invoicing features. OnlineInvoiceMaker is independent of any payment platform, giving you freedom to use any payment method or processor you prefer.
Instant Access
Start creating invoices the moment you visit the website. No Square account creation, no business verification, no payment setup. Square requires full account registration and business profile completion before you can send your first invoice.
Where Square Invoices Wins
Square Invoices excels when you are already embedded in the Square ecosystem. Its tight integration with Square POS hardware, Square Terminal, and Square Register means you can manage in-person and online payments from a single dashboard. Clients can pay invoices directly via credit card, Apple Pay, Google Pay, or ACH bank transfer without leaving the invoice. The Plus plan at $20 per month adds milestone-based invoicing for contractors and project-based businesses, automatic payment reminders, and custom invoice fields. For US-based businesses that want a unified payment and invoicing platform with built-in card processing, Square delivers a tightly integrated experience that standalone invoice generators cannot replicate.
The Verdict
Choose OnlineInvoiceMaker if you want a truly free invoice maker with no transaction fees, professional templates, GST support, and thermal printing on standard hardware. Choose Square Invoices if you are a US-based business already using Square POS and need integrated card payment processing on every invoice. For businesses outside the Square ecosystem, freelancers who want instant access without sign-up, or anyone needing GST compliance and extensive template customization, OnlineInvoiceMaker is the better choice and saves you 2.6% plus $0.10 on every transaction.
