Multi-Channel Ecommerce Bookkeeping: Shopify, Amazon & POS Under One Close Calendar

Run Shopify, Amazon, and POS under one close calendar. Channel payout mapping, consolidated reports, and CPA-reviewed month-end in QuickBooks or Xero.

Multi-channel growth breaks books when each platform speaks its own language. Our multi-channel ecommerce bookkeeping workflow runs Shopify, Amazon, and POS (plus gateways like Stripe/PayPal) under one close calendar with channel-level accuracy and a consolidated financial view. We standardize SKU mapping, convert each settlement into a consistent gross → fees → refunds/chargebacks → reserves = net deposit bridge, and reconcile every payout to bank statements. Inventory and COGS timing are aligned across channels (perpetual or periodic), and marketplace-facilitator tax is kept out of your liability while direct cart tax rolls to Sales Tax Payable by jurisdiction. Each month we reconcile all bank/credit/loan accounts, clear Undeposited Funds, tie AR/AP to the GL, and deliver a CPA-reviewed reporting pack (P&L by channel and consolidated, Balance Sheet, cash highlights) with a period-lock recommendation. The result: margins you can trust per channel, a single source of truth for lenders, and zero spreadsheet Frankenstein.

One Close Calendar That Doesn’t Slip

  • tickWeekly imports and exception clearing for each channel
  • tickMonth-end hard dates for settlements, IMS/FBA valuation, and tax roll-forwards
  • tick CPA review and period-lock on a fixed timeline (no back-posting)

Channel Bridges That Always Reconcile

Shopify

Payout mapping: gross – platform/gateway fees – refunds/chargebacks ± reserves = net deposit → bank line

Amazon

Settlement mapping: gross – referral/FBA – refunds/claims ± reserves = net deposit → bank line

POS / In-Store

 Z-reports/DSS mapping: gross sales – discounts – returns – tender fees = net deposit → bank; cash over/short tracked separately

Inventory & COGS Across Channels

  • tickSingle SKU master; channel aliases resolved to the master SKU
  • tick Choose item-level COGS (perpetual) or periodic COGS (IMS/FBA export) and apply consistently
  • tick Landed cost capitalization with a fixed allocation method (qty/weight/value)

Sales Tax Without Double-Counting

  • tick Facilitator orders (e.g., Amazon) = not your liability; memo disclosure only
  • tick Direct cart/POS = Sales Tax Payable by jurisdiction; reconcile to returns and bank payments
  • tickJurisdiction register with filing cadence and confirmations

Consolidated Reporting (What Execs & Lenders See)

  • tick P&L by channel + consolidated P&L with fee and COGS bridges
  • tickInventory valuation vs Inventory Asset reconciliation summary
  • tickFee, refunds/chargebacks, and reserve dashboards by channel
  • tickCash waterfall from settlements to bank

Month-End Checklist

  • tick Import and map all settlements (Shopify, Amazon, POS)
  • tickReconcile each payout to a bank line; UF = 0
  • tickValidate fees against statements; isolate reserves and releases
  • tickCompute/relieve COGS (perpetual) or compute periodic COGS from IMS/FBA
  • tickSales-tax roll-forward (facilitator vs direct) and filings calendar update
  • tickCPA review → variance note → period-lock guidance

Fix the 7 Multi-Channel Failure Modes

  • tick Duplicate revenue from gateway + platform feeds
  • tickFees logged twice (platform and gateway)
  • tickInventory not relieved on returns or restocks at wrong cost
  • tickReserves hitting expense instead of balance sheet
  • tickFacilitator tax added to Sales Tax Payable
  • tickPeriodic COGS posted late, random margin spikes
  • tickNo single close calendar, never truly “closed”

Reports You’ll Trust

  • tick Channel P&L bridges (gross to net)
  • tick Consolidated P&L and Balance Sheet with variance notes
  • tick Inventory/COGS tie-outs and trend lines
  • tick Sales-tax jurisdiction roll-forward and filing register
