Tesorio
Tesorio describes "AI agents that handle the full order-to-cash lifecycle" for enterprise and B2B SaaS finance teams: a Collections Agent that reads inbound email and drafts replies, automated dunning, cash application, AR forecasting, a Supplier Portals Agent for Coupa and Ariba, and a payment portal. See Tesorio alternatives.
Best fit: a finance team that wants AI agents across receivables without payables, close or treasury.
Accounting systems: NetSuite, Sage Intacct, QuickBooks and Workday, with other ERPs through Tesorio Connect.
Esker
Esker sells to "the Office of the CFO" and notes it suits organizations that have grown through acquisitions. Its receivables suite covers invoice delivery with e-invoicing compliance in more than 60 countries, collections, cash application, credit, deductions and online payments.
Best fit: a multi-entity or multi-country finance team, especially one running several ERPs.
Accounting systems: says over 70 ERPs; none named on its home page.
Billtrust
Billtrust serves B2B suppliers in industries such as distribution and manufacturing, with invoice delivery to email, AP portals, e-invoicing networks and print, a buyer payment portal, payments, cash application, collections and credit. See Billtrust alternatives.
Best fit: a supplier whose biggest job is getting invoices into buyers' systems and getting paid.
Accounting systems: says multiple ERPs; none named on the pages we read.
Upflow
Upflow is an AR platform for B2B finance teams, naming the CFO, controller and AR manager. It covers AR insights and forecasting, collections outreach, payments with a customer portal, cash application, and AI agents for collections and cash application.
Best fit: a mid-market B2B team, often in SaaS or services, that wants a receivables platform.
Accounting systems: NetSuite, Sage Intacct, QuickBooks Online, Xero, Pennylane and Rillet.
Gaviti
Gaviti describes an invoice-to-cash platform built around "Automated, personalized workflows that chase payments for you," plus cash application, credit checks, a payments portal and dispute routing.
Best fit: a finance team that wants collections workflows first.
Accounting systems: says it "Works with any ERP or business system"; none named.
The AR Agent
The AR Agent is much narrower and built for smaller businesses. The AI agent chases overdue invoices by email from the due dates in QuickBooks or Xero, reads and answers replies, tracks promises to pay, and brings disputes and judgement calls to a person.
It does not do cash application, deductions, credit, payments or e-invoicing, and does not connect to SAP, Oracle, Dynamics or NetSuite.
Best fit: a small or mid-sized B2B business on QuickBooks or Xero, without a collections team, that wants the chasing done.
Accounting systems: QuickBooks and Xero, with Gmail or Outlook.
