Aiwyn Payments is a billing, collections, and payments platform built specifically for accounting firms. It automates invoice delivery, payment reminders, aging-based follow-ups, and reconciliation, while giving clients a centralized portal to pay by ACH or credit card in one click. Firms use Aiwyn Payments to compress the billing cycle, reduce write-offs, and shorten days sales outstanding (DSO), turning AR from a back-office cost center into a predictable growth driver.
Aiwyn Payments is purpose-built for CPA and accounting firms, not e-commerce. It combines payments with firm-specific billing logic — WIP adjustments, smart statements, retainer and trust account handling, aging-based collections sequences, and engagement-letter-triggered autopay. Generic processors handle the transaction; Aiwyn Payments handles the entire bill-to-cash workflow that firms actually run, including how the firm communicates with clients about money.
Firms using Aiwyn have reduced DSO from a typical 60–90 days to as low as two weeks. The improvement comes from three compounding changes: invoices go out faster (automated, milestone- or schedule-based), clients pay more easily (one-click ACH and card payments in a unified portal), and follow-ups happen automatically based on aging rather than relying on a partner or admin to chase. Results vary by firm size and starting baseline, but most firms see meaningful DSO compression within the first two billing cycles.
Clients can pay by ACH or credit card from a single secure portal. They can pay a single invoice, multiple invoices at once, or set up autopay tied to engagement letters so the payment method is captured at signature. Saved payment methods let returning clients pay in one click without re-entering data, which is one of the biggest drivers of faster collection.
Yes. Aiwyn Payments sends invoices automatically based on fixed schedules or work milestones, then runs aging-based reminder sequences with tailored messaging at each stage. Firms can customize the cadence, tone, and escalation logic, so a 15-day-past-due reminder reads differently from a 60-day notice. This removes the manual chase work that typically falls on partners or billing admins and keeps collections consistent across the firm.
Aiwyn is SOC 2 compliant, and Aiwyn Payments uses bank-grade encryption for ACH and card data. Client payment information is tokenized and never stored on firm systems, which reduces PCI scope for the firm and protects sensitive financial data. Audit trails for invoices, payments, and refunds are built in for internal review and external compliance.
Aiwyn Payments integrates with the major practice management and general ledger systems firms already use, and is part of Aiwyn’s broader platform that connects payments, practice management, client experience, and tax. Firms can run Aiwyn Payments as a standalone AR layer on top of existing PM software, or consolidate to the full Aiwyn platform over time. The integrations ecosystem is designed so firms keep their current data sources of truth while still getting unified billing, payments, and reporting.
