Problem

Aiwyn solves the operational and cash-flow problems of modern accounting and CPA firms whose work is spread across legacy systems and disconnected point solutions. Manual invoice delivery, payment follow-up, collections, posting, and reconciliation consume partner and billing-team time, delay cash, increase days sales outstanding (DSO), and contribute to write-downs and revenue leakage. The central use case is bill-to-cash: getting invoices out faster, making it easier for clients to pay, and automating the follow-up and reconciliation work that firms otherwise handle manually.

Product / Service

Aiwyn is a software platform built specifically for accounting firms, combining four connected products: Aiwyn Payments for invoicing, digital payments, collections, and reconciliation; Aiwyn Practice for time, billing, projects, reporting, and resource management; Aiwyn Experience for portals, e-signatures, and document exchange; and Aiwyn Tax for AI-enabled tax preparation, review, filing, and workflow. Its payments product can operate as a standalone accounts-receivable layer over existing practice-management systems or as part of the broader platform, allowing firms to consolidate gradually.

The system automates scheduled or milestone-based invoicing, aging-based reminders, one-click ACH and card payments, payment matching, and reporting. The intended benefit is faster cash collection and lower DSO, while reducing administrative work, system switching, write-downs, and the time staff spend chasing payments instead of serving clients or performing higher-value work.

Market

Aiwyn competes in vertical accounting-firm technology, spanning practice management, accounts-receivable and payments automation, client experience, and tax technology. In practice management and firm workflow, relevant alternatives include Canopy, TaxDome, IRIS, Thomson Reuters Practice CS, and Ignition; generic processors such as Stripe or QuickBooks Payments address transactions, but Aiwyn positions itself around the broader accounting-firm bill-to-cash workflow. Its differentiation is the attempt to unify functions that are often bought separately, rather than remain only a payments product or only a practice-management system.

Aiwyn is a commercial, funded company rather than a pre-revenue startup. Its materials report more than 800 leading firms using or trusting the platform and, in May 2025, 175 of the top 500 accounting firms using Aiwyn as a point solution. The company announced a $113 million funding round led by KKR and Bessemer Venture Partners in December 2024. The evidence identifies substantial customer and financing traction but does not provide an official revenue or profitability figure.
