Stacks vs. Loopfour

Stacks is a type of finance automation solution designed to streamline the month-end close process for finance teams. Unlike traditional systems that rely on rigid rules and manual inputs, Stacks leverages advanced agentic AI to create adaptive workflows that learn and optimize over time. This innovative approach significantly reduces the burden of month-end close activities, allowing finance professionals to focus on delivering insights rather than maintaining cumbersome processes.

Loopfour automates your most painful finance workflows as deterministic, auditable code, not black-box AI, on top of the tools you already use. Every workflow runs as real code, identical on run #1 and run #1,000,000, with a full audit trail on every action. We connect the systems you already own (Workday, NetSuite, Salesforce, Stripe, QuickBooks, and more) and automate the work between them: contract-to-cash, cash application, AR and dunning, credit memos, revenue recognition, AP, and more. You name the workflow your team dreads. We build it, run it, and maintain it.
