About us

One trusted source of
financial truth.

Blue Onion is the financial intelligence platform for e-commerce. We reconcile every order, payment, fee, refund, and bank deposit into one transaction-level record that finance teams can actually rely on.

Why we exist

The money never matches the orders that created it.

When a brand sells on Shopify, Amazon Seller, TikTok Shop, and in retail, and settles through several payment processors, the cash arrives days later in net amounts that look nothing like the sales behind them. Fees, refunds, chargebacks, reserves, and currency conversion all get bundled into a single deposit.

Most finance teams close that gap by hand, in spreadsheets, every single month. And that is not a staffing problem. It is a data problem.

If nobody can trace a deposit back to the orders behind it, then everything downstream rests on something nobody has verified. The close. The margin analysis. The board deck. The audit. The forecast. All of it inherits whatever was missed.

We started Blue Onion in 2020 to fix that at the source: reconcile the data first, at the transaction level, and let every other number in the business be built on top of something that ties out.

Three modules, one reconciled foundation.

Close

For controllers and accountants

Reconciles every payout automatically and produces ERP-ready journal entries, so month-end close becomes a review instead of a rebuild.

Fabric

For CTOs and data teams

Exposes clean, reconciled financial data through APIs and event streams, so warehouses, BI tools, and AI agents run on numbers that already tie out.

Edge

For CFOs and business leaders

Explains what moved and why, decomposing margin shifts by channel mix, returns, fees, currency, and product.
