The financial intelligence platform that reconciles every order, payout, fee and refund - from checkout all the way to the bank - so finance teams close their books daily with accuracy.
Every finance team at a growing consumer brand keeps a spreadsheet they are quietly afraid of. It is the one that ties orders to payments to the money that actually lands in the bank - and it breaks a little more each month. Blue Onion was built to delete that spreadsheet.
Founded in 2020 and headquartered at 800 3rd Avenue in New York, Blue Onion Labs Inc. builds an automated financial subledger for retail and e-commerce companies. Its proprietary data engine ingests transactions from order systems, payment processors, marketplaces and bank accounts, then reconciles every order, payout, fee, refund and deposit into a single financial foundation the company describes as one source of truth.
The problem it attacks is unglamorous and expensive. When a brand sells across Shopify, Amazon, TikTok Shop and its own site, a single bank deposit can bundle together dozens of orders, refunds, marketplace fees and reserves. Untangling that by hand is the reason a month-end close routinely stretches five to ten days. Blue Onion decomposes those bundled payouts automatically and books the entries, compressing the close to one to two days.
Where generic accounting automation stops at estimates, Blue Onion reconciles at the transaction level and encodes the finance logic e-commerce actually runs on: ASC 606 revenue recognition, gift-card issuance and breakage, chargebacks, partial refunds, cash-in-transit, channel mix, processor fees and foreign exchange. The company positions the result not just as bookkeeping relief, but as the clean, structured data layer that finance AI will need to be trustworthy.
That framing is the pitch behind its April 2025 raise - a $10 million Series A led by Viola FinTech that brought total funding to $17.6 million. It is a bet that the next generation of automated finance is only as good as the reconciled data underneath it.
