The finance AI problem
The real AI risk in finance isn’t slowness. It’s exposure.
Your board wants AI in finance, and your auditors want it to hold up. But finance does not run on “probably.” An LLM that invents a number, silently cuts a corner, or cannot show its work is not an efficiency gain. It is a liability you have to sign your name to at close.
There is a fourth option: automation you can defend, with a full evidence trail under every action.
DIY agents and scripts
Something a sharp operator vibe-codes can work, until it drifts, breaks, or leaves with the person who built it. Then nobody can show how a number was produced.
Doing nothing
Your control environment stays exactly as thin as it is today, while your team keeps burning days on report pulls, reconciliations, and copy-paste between systems.
What Loopfour is
Deterministic workflow automation for finance.
Loopfour automates AR, close, and revenue recognition as deterministic, auditable code, not black-box AI, on top of the tools you already use.
Real code, not runtime guesses
Every workflow runs a fixed, versioned set of steps. Any change to a live workflow creates a new version, and every version is retained.
Scoped AI where it belongs
AI can read a contract or classify a document, but confidence thresholds and human fallback keep it from deciding what your finance system does.
Full execution evidence
Every action, approval, exception, and system write is logged so finance leaders and auditors can inspect the run instead of trusting a black box.
What you can automate
The finance workflows teams hand us first.
Each one runs as deterministic code on the systems you already use, with approvals where you want them and an audit trail underneath all of it.
Accounts Receivable & Collections
Automated invoicing, dunning, and cash application across the order-to-cash cycle. Every reminder sent and every payment matched is logged against the invoice.
Accounts receivable automationAccounts Payable & Invoice Processing
Capture the invoice, run the match against the PO and receipt, route approvals to the person who owns the spend, and keep the evidence attached to the payment.
See AP workflowsRevenue Recognition & Contract-to-Cash
ASC 606 schedules derived from the contract, deferred revenue tracked as it releases, and the same journal entries booked the same way every period.
Revenue recognition automationPayment Reconciliation & Cash Application
Deterministic matching across your bank, ERP, and payment rails. Exceptions route to a person with the context attached instead of landing in a spreadsheet.
Account reconciliation automationMonth-End Close
Reconciliations, journal entries, and close checklists that run on schedule, with the audit evidence captured as the work happens rather than reassembled afterward.
Month-end close automationWhy deterministic matters
Auditors test controls, not tools. Loopfour gives them a versioned workflow, an approval record and a log of every run.
We use AI where it belongs, such as interpreting a document, but never to decide what your finance system does.
For public companies, AS 2201, an audit of internal control over financial reporting (opens in a new tab) sets out how an audit of internal control over financial reporting is performed.

Public-company controls
A public company on Workday runs Loopfour with SOC 1 evidence captured on every workflow run. Loopfour completed a SOC 2 Type II examination covering February 1, 2025 to January 31, 2026, performed by Percilchofe CPA LLC. The examination covered the Security, Availability and Confidentiality trust services criteria for the Loopfour and JustPaid products. Loopfour completed a SOC 1 Type I examination of the Loopfour platform as of June 15, 2026, performed by Assurion Services LLC. The examination covered the design of controls relevant to customers' internal control over financial reporting.

Billing process compressed
A $75M ad company moved a billing process that touched 25 people over six days into an 18-minute workflow where only exceptions reach a human.
Before: calendar time from first report pull to last invoice posted in one monthly billing cycle, as reported by the customer's finance lead, with 25 people involved. After: median run time of the Loopfour workflow from trigger to final post in one billing cycle about 30 days after go-live, exceptions excluded. Six days is elapsed calendar time, not labor hours. Exception handling is additional.

Workflow Engine
You stay in control
Your controls stay yours. We carry the maintenance.
Loopfour sits between the systems you already trust and turns repeatable finance work into governed workflows that you and your auditors can inspect.
Permissions, approvals, impact analysis, and a full audit trail: see how governance works.
A SOC 2 report is the result of an examination performed under AICPA attestation standards (opens in a new tab), and the AICPA publishes an overview of the SOC suite (opens in a new tab).
No rip-and-replace
Keep the ERP, CRM, payment processor, document tools, and approval process your team already uses.
No key-person risk
Workflows live in a managed platform with version history, not in one analyst’s local script or private prompt chain.
No maintenance burden
When an upstream tool changes or repeated exceptions show a rule needs to change, Loopfour handles the update with your approval.
Gated by design
No workflow goes live without the approvals your controls require, and exceptions wait for the right owner before anything posts.
Bring the finance workflow you have to defend at audit. We will map the automation path.
In 45 minutes, walk through billing, cash application, reconciliation, or whichever process carries the most close and audit risk. You leave with a scoped plan for how Loopfour would run it on your stack with deterministic controls and audit-ready evidence.
