QuickBooks Online Sync

Kill the bookkeeper export.

Most FBA brands still pay someone $400–$1,200 a month to re-key Amazon settlement reports into QuickBooks — BuyCast does it automatically, with more detail, in seconds.

One-click connect via Intuit’s official OAuth flow · No API keys to manage

PO receipt \u2192 vendor bill, automatically

Every time you receive inventory in BuyCast, a Vendor Bill posts to QuickBooks Online with the correct vendor, line items, per-unit cost, freight, and discounts already baked into landed cost. No CSV. No copy-paste. Your books stay current the moment product hits the shelf.

Amazon settlement \u2192 balanced journal entry

Each two-week Amazon deposit maps to separate lines for sales, shipping, refunds, promos, referral fees, FBA fees, reimbursements, advertising, and tax withheld \u2014 plus a clearing line that matches the bank deposit for one-click reconciliation.

Per-tenant Chart of Accounts mapping

Map each BuyCast category to the QuickBooks account where it should post. BuyCast remembers the mapping and applies it to every future push. Change your mind later? Update the mapping; the next sync picks it up.

Built for operators who actually care about their books

Idempotent pushes. Full audit trail. Zero duplicates.

Every push is logged in a Sync Log with full audit trail. Retries are idempotent — if a network hiccup causes a retry, BuyCast will never double-post a transaction. If a push fails, you can inspect the error and retry it from the log with one click. Connection uses Intuit’s official OAuth flow — no API keys to manage, no tokens to rotate.

We validated the full pipeline against a live Intuit sandbox on May 12, 2026: a real PO-receive posted a Vendor Bill, and a real $88K Amazon settlement with 29,000+ individual line items posted a balanced Journal Entry. QuickBooks accepted both on the first attempt.

Xero sync ships next on the same connector layer.
