### Invoiced

Invoiced by Flywire is an AI-native accounts receivable and invoice-to-cash automation platform designed to help B2B finance teams automate billing, collections, payment processing, and cash reconciliation. Built for mid-market and enterprise businesses managing high-volume receivables, Invoiced eliminates manual A/R work so finance teams can scale operations without adding proportional headcount. Acquired by Flywire (NASDAQ: FLYW) in 2024, Invoiced combines accounts receivable software, AI-powered automation, integrated payment processing, and deep ERP integrations into a single connected platform. Unlike point solutions or freelance invoicing tools, Invoiced is purpose-built for complex B2B finance operations where invoice volume is high, payment methods are diverse, and reconciliation is time-consuming. Core Capabilities & Features: -Automated Collections Workflows — Customizable dunning sequences, payment reminders, and escalation rules that trigger based on payment status and customer behavior, reducing manual follow-up work -AI-Powered Cash Application — CashMatch AI automates payment matching and reconciliation to invoices, even with incomplete remittance data, minimizing exceptions and month-end reconciliation time -Subscription & Recurring Billing — Supports usage-based, recurring, and hybrid billing models with automated invoice generation, proration, and customer billing portals -Global Payment Processing — Accepts 1,200+ payment methods across 140+ currencies with automatic FX handling, enabling domestic and cross-border collections without adding banking complexity -Deep ERP Integrations — Native connectors to NetSuite, Sage Intacct, Microsoft Dynamics 365, Salesforce, and others ensure real-time data sync and eliminate duplicate data entry Finance teams use Invoiced to accelerate cash collection, reduce days sales outstanding (DSO), and regain visibility into the full receivables lifecycle. The platform eliminates data silos between AR, payments, and ERP systems by automating payment reconciliation and posting. Routine manual tasks—invoice delivery, payment chasing, cash matching, exception handling—are shifted to AI-driven workflows, freeing finance professionals to focus on strategy, forecasting, and relationship management rather than execution. The platform is particularly valuable for organizations scaling transaction volume without scaling headcount, companies operating internationally with multi-currency and multi-payment-method requirements, and finance teams struggling with legacy systems that lack automation and integration. Invoiced serves mid-market and enterprise finance teams across industries including SaaS, healthcare, education, financial services, insurance, professional services, staffing, and nonprofits. Thousands of global customers rely on Invoiced to process billions in receivables annually, and the platform is recognized as a category leader in A/R automation.

Tax services are offered by firms which specialize in filing and preparing taxes. Often these services are provided by [accounting firms](https://www.g2.com/categories/accounting-firms). Tax firms use their in-depth understanding of complex regulations to offer expertise and guide corporations through the tax process. These services can often save businesses time and money, as well as help ensure legal compliance. Corporations will usually work with firms year-round but will have the most contact in the time leading up to important state and federal tax deadlines. Businesses of all sizes and industries work with these providers and generally assign their accounting departments to coordinate with the firm.
