Blue Onion vs A2X

At a glance

What is A2X?

A2X is a settlement-to-general-ledger connector for ecommerce. It ingests each marketplace or payment-processor settlement (for example, an Amazon Seller payout every ~14 days or each Shopify payout), splits it into revenue, refunds, fees, and taxes, and posts a single summary journal entry to your accounting software so the entry matches the deposit in your bank.

A2X is a strong fit when a business sells on one channel or primarily needs its books to tie out at the payout level.

What is Blue Onion?

Blue Onion is the financial intelligence platform for ecommerce. Before any reporting happens, it reconciles financial data at the transaction level across every sales channel, payment processor, and bank payout, and builds one continuously reconciled source of truth. On top of that foundation, the Close module reconciles every payout automatically and produces daily journal entries, turning month-end close into a one-day review instead of a multi-day project; Fabric exposes clean, reconciled data to APIs, models, and AI agents; and Edge (coming soon) decomposes margin shifts for CFOs and business leaders.

Blue Onion is built for scaling or high-volume, multi-channel retail and ecommerce brands, including those selling on Shopify, Amazon Seller, and TikTok Shop, where summary-level entries hide the detail finance teams need.

The core difference: summary-level vs transaction-level

This is the decision that matters most.

A2X works at the payout/summary level. It tells you that a $48,000 Amazon Seller payout breaks into revenue, fees, and refunds, and books that as one entry. That's clean and fast, but it doesn't preserve which orders, products, or customers drove the numbers. For a single-channel seller, that's usually fine. For a brand selling across Shopify, Amazon Seller, TikTok Shop, and retail, with multiple processors and refunds and chargebacks flowing on different timelines, summary entries can hide discrepancies and make order-level questions hard to answer.

Blue Onion works at the transaction level. Every order is reconciled from the sale through the processor to the bank deposit and into the ERP, so the detail is preserved and queryable. A structural reason this is possible: Blue Onion connects directly to the payment processors and banks, while A2X instead reads the settlement report each channel hands off, so Blue Onion can reconcile the full order-to-cash path rather than just book the payout total. That granularity is what lets finance teams catch discrepancies in time to act on them, answer margin and product-level questions, and hand AI tools data they can actually trust.

When A2X is the right choice

• You sell on one or a small number of channels.
• You mainly need your books to reconcile at the payout level.
• A bookkeeper manages your close and wants clean summary entries.
• Order-level detail, audit trails, and multi-channel reconciliation aren't pain points yet.

When brands choose Blue Onion

• You're reconciling across multiple channels and processors and the volume and/or complexity has created a significant amount of manual work.
• You need order/transaction-level accuracy for audit, tax, and margin analysis.
• Month-end close is slow because data is fragmented across systems.
• You want a clean, reconciled data layer your ERP, BI, and AI tools can run on.
• You're a controller, CFO, or CTO who needs one source of financial truth, not just tidy books.

FAQ

Is Blue Onion an A2X alternative?

Yes, but they solve different depths of the same problem. A2X posts summary journal entries per payout; Blue Onion reconciles at the transaction level across the full stack and builds a continuously reconciled source of truth. Brands typically move toward Blue Onion when summary-level payout entries are not enough and they're looking for the transaction-level detail and multi-channel coverage they need.

Does A2X do transaction-level reconciliation?

A2X is designed around summary-level entries: it aggregates each settlement into a single journal entry rather than tracking individual orders. This keeps books clean but limits order-level insight.

Does Blue Onion work with NetSuite and QuickBooks?

Yes. Blue Onion connects to NetSuite, QuickBooks, and the broader ecommerce and payments stack, and produces ERP-ready entries.

Which is better for multi-channel brands?

For brands selling across several channels with multiple payment processors, transaction-level reconciliation generally scales better than summary entries because it preserves the detail needed to reconcile and analyze across systems. Evaluate both against your channel count, volume, and reporting needs.
