What Are Invoice-to-Cash Applications?

Gartner defines the invoice-to-cash (I2C) applications market as cloud-based applications that enable corporate controllers to automatically manage collections and apply customer payments to invoices. I2C applications typically gather, disseminate, track and analyze data from and to internal and external sources. They make I2C processes more efficient and effective, including managing and monitoring deductions, disputes and credit risk. They also typically can ensure invoices are delivered to customers and that customers have options to pay them. I2C applications enable I2C transaction processing across multiple ERP systems.
Organizations use I2C applications to collect and apply customer payments to open invoices, perform credit and collections activities, manage deductions and disputes, and deliver and present invoices to customers for payment. I2C applications are cloud-based tools that provide organizations with a standard way of processing across ERPs, while creating flexibility for buyers in how they receive or access invoices as well as pay and dispute them.
I2C applications allow an organization to connect and exchange data with multiple ERP systems and other operational tools, such as customer relationship management tools, as well as with partners such as credit and collections agencies, logistics providers, banks and payment service providers. They use data to determine credit risk, automate collections and cash applications activities as well as help manage the resolution of deductions and disputes. Such activities result in faster collection of cash, improved visibility to cash flow, an improved customer experience and reduced process cost.

What Is Gartner Peer Insights “Voice of the Customer”?

“Voice of the Customer” is a document that synthesizes Gartner Peer Insights reviews into insights for buyers of technology and services. This aggregated peer perspective, along with the individual detailed reviews, is complementary to Gartner expert research and can play a key role in your buying process. Peers are verified reviewers of a technology product or service, who not only rate the offering, but also provide valuable feedback to consider before making a purchase decision.
Along with the historical peer-based perspective represented in this document, Gartner has a related expert-led Magic Quadrant for the invoice-to-cash applications market. For related research in this market, please visit the Magic Quadrant for Invoice-to-Cash Applications.
Figure 1 shows all “Voice of the Customer” eligible vendors in the market categorized into four quadrants based on scores assigned for User Interest and Adoption (x-axis), and Overall Experience (y-axis). The midpoint of each axis, labeled “market average,” represents the average score as calculated exclusively from vendors included in the document.
Vendors’ User Interest and Adoption (x-axis) scores incorporate three factors: review volume, user willingness to recommend, and review market coverage across industry, company size and region. Vendors’ Overall Experience (y-axis) is a composite score that incorporates average user ratings for “Overall Experience,” “Capabilities” and “Support/Delivery.” See the Methodology section for more detail.

All vendors are classified under specific quadrants based on their “overall experience,” and “user interest and adoption.” The Customers’ Choice quadrant in the upper right represents the highest overall experience, and maximum user interest and adoption. Strong Performer is in the upper left. Aspiring is in the lower left. Established is in the lower right. Eligible vendors as of October 2025 — Customers’ Choice vendors: HighRadius; Strong Performer vendors: Esker, Sidetrade; Aspiring vendors: Billtrust, Microsoft; and Established vendors: Quadient.
Vendors placed in the upper-right “Customers’ Choice” quadrant of the “Voice of the Customer” have scores that meet or exceed the market average for both axes (User Interest and Adoption, and Overall Experience).
Vendors placed in the lower-right “Established” quadrant have scores that meet or exceed the market average for User Interest and Adoption, but are below the market average for Overall Experience.
Vendors placed in the upper-left “Strong Performer” quadrant have scores that meet or exceed the market average for Overall Experience, but are below the market average for User Interest and Adoption.
Vendors placed in the lower-left “Aspiring” quadrant have scores below the market average for both User Interest and Adoption, and Overall Experience.

Methodology

A full description of the methodology can be found on the Gartner Peer Insights Voice of the Customer Methodology page.
Voice of the Customer includes vendors with products aligned to the market that have 20 or more eligible published reviews (and 15 or more ratings for “Capabilities” and “Support/Delivery”) during the 18-month consideration period ending 31 October 2025. Reviews from vendor partners or companies with less than $50 million in revenue are excluded.
In the invoice-to-cash applications market, Gartner Peer Insights published 386 reviews and ratings during the consideration period. For details, see Gartner Peer Insights Voice of the Customer Methodology.
The data used in this report is drawn from reviews on Peer Insights, a free peer review and ratings platform that regularly publishes new reviews. The “Voice of the Customer” methodology uses a snapshot of reviews data from a defined timeframe and does not automatically update as new reviews are published. The external Peer Insights site will always have the most updated peer view of the vendors and products in this report.
The numerical ratings scores in each vendor summary graphic (shown as “Rating by Category”) are best interpreted as sample statistics with a reasonable margin for error and not as exact values.
