Revaly is built to solve one of the most costly and overlooked problems in subscription commerce: legitimate payments failing for preventable reasons. Its end-to-end Payment Performance Management platform leverages machine learning, issuer intelligence, and ecosystem data to elevate approval rates starting from the very first transaction attempt. The system automatically detects issues such as mistyped card numbers, routing mismatches, and metadata errors before a customer ever checks out. When payments do fail, Revaly uses a sophisticated retry engine that studies customer behavior, card network patterns, and historical success windows to recover revenue without damaging relationships. Businesses across industries report dramatic improvements—from 34% to over 50% increases in recovered payments—demonstrating the compound value of consistent, optimized approvals. Revaly’s integration ecosystem makes adoption frictionless, connecting seamlessly with CRMs, billing systems, payment gateways, and processors already in use. The platform not only protects revenue but stabilizes growth by reducing churn that comes from unintentional payment failures. Leadership teams gain visibility into payment performance metrics that go far beyond authorization rates, revealing hidden revenue opportunities and operational inefficiencies. As a result, companies can build smarter billing strategies and deliver a more reliable experience for customers.

Running a local means keeping track of members, employers, contracts, dues, grievances, and elections, often across spreadsheets and an aging database nobody wants to touch. eMembership replaces that patchwork with one system designed only for labor unions. Here's what changes for your staff. Dues posting handles classification-based rates and remittance from many employers. Grievance deadlines come from your contract, and reminders reach the assigned rep before a step is missed. Organizers track field activity in the same place staff log member calls. Meetings and Events, surveys, and DOL-compliant elections run inside the platform instead of a separate tool. Here's what changes for members. They download a native app for iOS or Android, or log in on the web, to pay dues, update contact details, and see where their issues stand. Fewer calls come into the hall. Getting started is predictable. A fixed-scope, fixed-price Discovery Project defines the work up front. Your records move into a parallel environment, your team checks them, and you go live only after sign-off. Support comes from a US-based team with defined response targets, and two updates a year are included. Cost stays predictable as you grow, because you pay for modules, not members or staff seats. That's why 55+ unions across the US and Canada, most of them locals, use eMembership. Labor union software, built for the way locals actually run.
