Gateway only charges 10¢ per transaction plus a 10¢ daily batch fee, but does not include a merchant account. Gateway + eCheck lists 0.75% eCheck processing and separate credit-card fees. Compare the fee model that fits your payment mix, not just the monthly price.
03Features and depth
These products overlap on online payments, but they do different jobs. Authorize.Net is a payment processor for online, phone, mobile, and in-person sales. Its listed features include card, eCheck, and digital-wallet payments; a virtual terminal for phone orders; virtual point of sale; QR-code and tap-to-pay options; fraud detection; and website checkout buttons. Its plans also include recurring billing and digital invoicing.
Invoice Ninja is invoicing and small-business operations software. It offers branded invoices with 11 templates, recurring invoices, expense and vendor tracking, time tracking, projects, Kanban boards, and a client portal. Clients can pay invoices through supported gateways including Stripe, PayPal, Square, and GoCardless. Paid plans add options such as unlimited clients, API access, and user permissions. The published gateway list does not name Authorize.Net as an Invoice Ninja payment option, so confirm compatibility before treating the two as a combined setup. Choose based on whether payment acceptance or invoicing and business admin is the main need.
04Ease of use and learning curve
The available reviews give Invoice Ninja an ease-of-use score of 8 and Authorize.Net a 6; those scores are a useful signal, not a guarantee for every business. Invoice Ninja’s free plan lets a solo business start with up to five clients, while Authorize.Net’s listed plans all carry a $25 monthly fee.
The scope matters too. Invoice Ninja brings invoicing, expenses, time, and project tools together, so there are more workflows to consider. Authorize.Net focuses on payment acceptance across several channels, with different plan fees depending on whether you need a merchant account or eCheck processing. The published information does not detail setup steps for either product, so we would not assume one has a shorter onboarding process.
