Selling on Amazon and Shopify at the same time solves a real problem: Amazon’s reach plus a storefront you actually control. It also creates one, almost immediately. Two order streams, two sets of fees, and two separate bookkeeping trails to reconcile at month-end.
In Vedron they share the same orders, stock and ledger.
Where double bookkeeping comes from
It is rarely the selling that is hard. It is what happens after. Amazon settles in batched payouts every two weeks, net of referral fees, FBA fees and refunds. Shopify (through Shopify Payments or a separate gateway) settles per-transaction or in its own payout cycle. If each channel’s orders and payouts land in a separate spreadsheet or a separate accounting import, two trails emerge that have to be reconciled by hand.
Stock is the other half. If Amazon and Shopify each think they have the full quantity of a SKU, a bike frame that is actually down to one unit can get oversold on both channels in the same afternoon.
What needs to sync, and how often
Three things need to move automatically. Orders — a sale shows up in one place, once, regardless of channel. Stock — both channels see the same quantity, adjusted the moment either one sells a unit. Payouts — a settlement is reconciled against the orders it covers, not treated as one unexplained lump sum.
Order sync should be near-real-time: Amazon’s SP-API and Shopify’s Admin API on a short interval, not an overnight job. Overselling risk is highest in the hours between syncs.
What runs today in Vedron
Vedron’s Amazon integration (SP-API) and Shopify integration write into the same order and stock tables as every other connected channel. A sale on either platform adjusts one shared stock number immediately, so the other channel reflects it right away. A dropship-aware pool covers SKUs you do not stock yourself.
Amazon payouts are reconciled against the orders they cover. Fees are posted per category — referral, FBA, advertising, refund — against the right period, so the gap between gross sales and the amount that landed in your bank is explained line by line.
Common questions
Do I need separate SKUs for Amazon and Shopify? No. One SKU, one stock number, mapped to each channel’s own listing ID.
What happens to FBA-held inventory? FBA stock is tracked as its own pool but still counted against the same product record, so your Shopify listing reflects the combined availability.
Does this replace my accountant? No. It removes the manual matching so what reaches your accountant is already reconciled.
