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
Weekly imports and exception clearing for each channel- Month-end hard dates for settlements, IMS/FBA valuation, and tax roll-forwards
- 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
- Single SKU master; channel aliases resolved to the master SKU
- Choose item-level COGS (perpetual) or periodic COGS (IMS/FBA export) and apply consistently
- Landed cost capitalization with a fixed allocation method (qty/weight/value)
Sales Tax Without Double-Counting
- Facilitator orders (e.g., Amazon) = not your liability; memo disclosure only
- Direct cart/POS = Sales Tax Payable by jurisdiction; reconcile to returns and bank payments
- Jurisdiction register with filing cadence and confirmations
Consolidated Reporting (What Execs & Lenders See)
- P&L by channel + consolidated P&L with fee and COGS bridges
- Inventory valuation vs Inventory Asset reconciliation summary
- Fee, refunds/chargebacks, and reserve dashboards by channel
- Cash waterfall from settlements to bank
Month-End Checklist
- Import and map all settlements (Shopify, Amazon, POS)
- Reconcile each payout to a bank line; UF = 0
- Validate fees against statements; isolate reserves and releases
- Compute/relieve COGS (perpetual) or compute periodic COGS from IMS/FBA
- Sales-tax roll-forward (facilitator vs direct) and filings calendar update
- CPA review → variance note → period-lock guidance
Fix the 7 Multi-Channel Failure Modes
- Duplicate revenue from gateway + platform feeds
- Fees logged twice (platform and gateway)
- Inventory not relieved on returns or restocks at wrong cost
- Reserves hitting expense instead of balance sheet
- Facilitator tax added to Sales Tax Payable
- Periodic COGS posted late, random margin spikes
- No single close calendar, never truly “closed”
Reports You’ll Trust
- Channel P&L bridges (gross to net)
- Consolidated P&L and Balance Sheet with variance notes
- Inventory/COGS tie-outs and trend lines
- Sales-tax jurisdiction roll-forward and filing register
