Blue Onion raises $10 million in Series A funding to expand its AI-driven financial subledger platform for ecommerce and retail finance teams. The system automates daily bookings and validates data at the source, eliminating manual reconciliation and reducing ERP costs. With over $30 billion in transactions processed and 99% accuracy, the platform supports real-time financial operations at scale.
$10M and Counting: Why Investors Bet Big on Blue Onion
Blue Onion announced a $10 million Series A funding round led by Viola FinTech, bringing its total funding to $17.6 million. Existing investors Vinyl, Entree Capital, Green Visor, and Y Combinator also participated. The funding supports the company’s effort to advance financial operations automation for ecommerce and retail teams.
This investment reflects growing demand for more reliable and efficient finance tools in commerce environments. Blue Onion’s focus on automating the order-to-cash cycle with a high degree of accuracy plays a central role in its funding momentum. The capital will be directed toward enhancing product capabilities, expanding system integrations, strengthening go-to-market efforts, and growing technical accounting support.
Inside the Engine: How Blue Onion’s AI Subledger Actually Works
Blue Onion’s core product is a subledger designed to automate daily bookings and financial reconciliation. It integrates directly with order systems, payment processors, and bank accounts to provide a seamless data flow from transaction to ledger entry.
Unlike traditional systems that validate data after it enters the ERP, Blue Onion performs validation at the source. This prevents manual errors, eliminates the need for expensive and often faulty third-party data connectors, and removes reliance on time-consuming reconciliation processes.
The platform has reconciled over $30 billion in transactions and achieves an average accuracy rate of 99%. Its subledger adapts and scales with growing transaction volumes, using AI to continuously learn and improve.
Why Month-End Close Is Officially Outdated
Month-end and year-end closings have long been seen as unavoidable for finance teams, often resulting in estimated numbers, inconsistent reporting, and delayed insights. Blue Onion shifts this paradigm by enabling a daily close process.
By automating every step from ingestion to reconciliation, the platform allows accounting teams to close their books daily with consistent, audit-ready accuracy. This transforms the role of finance operations from reactive to proactive.
Several case studies show measurable improvements:
- Public Rec moved reconciliation in-house, achieving 99.5% accuracy.
- Clean Simple Eats reduced its month-end close from over 60 hours to under 5.
- Supergoop! automated reconciliation for more than 200,000 monthly orders, eliminating manual data entry.

What This Means for Retail and Ecommerce Finance Teams
Blue Onion supports finance teams in managing large volumes of transactional data across multiple systems without additional engineering. Its methodology helps organizations replace error-prone spreadsheets and complex connector tools with a unified, automated workflow.
Key impacts include:
- Reducing dependency on manual reconciliation processes
- Increasing audit-readiness with complete transaction visibility
- Minimizing ERP connector costs and transaction fees
- Supporting growth without adding operational headcount
The subledger ensures validated financial data before it enters ERP systems, improving data accuracy and reducing downstream cleanup work. This is especially critical during audits, board reporting, and fundraising preparation.
Where Blue Onion Takes Financial Automation From Here
The Series A funding enables Blue Onion to deepen its product development across several fronts. Planned initiatives include broader integration with accounting platforms, improved in-app customization, and enhanced AI-based workflows.
The company is expanding its technical accounting team to provide customers with expert guidance throughout implementation and scaling. These additions aim to help customers fully utilize the platform’s capabilities and improve financial transparency.
Blue Onion’s roadmap focuses on workflow efficiency and sustained accuracy across a wider range of commerce environments. The emphasis remains on reducing manual effort while maintaining data integrity at scale.
The Platform That Finance Teams Actually Want to Use
Finance professionals using Blue Onion report faster closing times, improved visibility, and reduced friction in the order-to-cash lifecycle. The ability to trace each transaction from order to bank payout strengthens confidence in the data and removes uncertainty during reporting periods.
By removing the need to choose between speed and accuracy, Blue Onion enables teams to act on reliable financial data without operational delays. Trusted by over 200 ecommerce and retail brands, the platform positions itself as a consistent data source built for high-volume, high-complexity environments.
