Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

What is Stax?
Stax is an all-in-one payment technology platform built for businesses that have outgrown flat-rate processors. With subscription-based pricing and 0% markup on direct-cost interchange, Stax saves businesses up to 40% on payment processing fees — no hidden costs, no percentage markups.
The platform includes Stax Pay for in-person, online, and mobile payment acceptance; Stax Bill for automated recurring billing and invoicing; CardX for compliant credit card surcharging; and Stax Connect, an embedded payments solution that enables SaaS companies and ISVs to integrate full-stack payment processing directly into their software.
As an end-to-end processor, Stax handles the entire transaction lifecycle in-house — from authorization to settlement — giving businesses and software platforms more control, better economics, and dedicated support. Over 30,000 businesses trust Stax to process more than $30 billion in payments.
