E-Commerce Bookkeeping Services
E-commerce bookkeeping is the process of recording, categorizing, and verifying every financial transaction that flows through an online business. Unlike traditional retail, where a single point-of-sale system captures each sale, online sellers deal with payment processors, marketplace fees, nexus obligations, cross-border transactions, and constantly shifting product costs—all happening simultaneously across multiple channels.
What Is E-Commerce Bookkeeping?
At Maxim Liberty, we have managed e-commerce bookkeeping for online sellers since 2005. Our team works inside your platforms daily, matching settlement reports to bank deposits, tracking cost of goods sold, and keeping your books tax-ready so you can focus on growing revenue instead of chasing numbers.
Core Bookkeeping Challenges for Online Sellers
Running an online store generates far more financial complexity than most sellers expect. Here are the challenges we solve for our clients every day.
Payment Processor Matching
Stripe, PayPal, Square, and marketplace-native processors all take their cut before depositing funds into your bank account. Without proper bank reconciliation, your revenue numbers will never match your bank deposits. Our bookkeepers verify each processor payout against your accounting records weekly, catching discrepancies before they compound.
Multi-Channel Revenue Tracking
Most online sellers operate across more than one channel—their own website, Amazon, Shopify, or eBay. Each channel reports revenue differently and on different timelines. We consolidate all revenue streams into a single, accurate picture so you know exactly which channels drive profit and which drain margin.
Inventory and Cost of Goods Sold (COGS)
Between supplier price changes, shipping costs, duties on imported goods, and platform storage fees (like Amazon FBA warehousing), the true landed cost of each unit sold is rarely straightforward. We calculate COGS at the SKU level, giving you accurate gross margins that reflect your actual business reality.
Multi-State Tax Compliance
Since the South Dakota v. Wayfair decision, economic nexus thresholds mean that reaching even modest revenue in a state can trigger filing requirements. We track your nexus exposure, calculate collected vs. owed amounts, and provide the audit-ready data your tax preparation team needs to keep you compliant.
Returns, Refunds, and Chargebacks
Online retail return rates run significantly higher than brick-and-mortar. Each return involves reversing revenue, adjusting stock levels, and potentially eating restocking costs. We track every reversal so your P&L reflects actual earned revenue, not gross sales inflated by returns.
Platform-Specific Bookkeeping Expertise
Every e-commerce platform generates financial data differently. Our bookkeepers are trained on the specific reporting quirks, fee structures, and verification workflows for each major marketplace.
Amazon and FBA Sellers
Amazon settlement reports bundle product revenue, shipping credits, FBA pick-and-pack fees, referral fees, advertising costs, and reimbursements into lump-sum payouts. We break down each settlement into its component transactions, match FBA fees against actual product movements, and monitor reimbursement claims for lost or damaged warehouse stock.
Shopify Stores
We match Shopify payouts against your bank deposits, track transaction fees separately from COGS, and integrate your Shopify financial data with QuickBooks or Xero for clean month-end closes.
eBay & Etsy Sellers
For high-volume eBay and Etsy sellers, the sheer transaction count makes manual verification impractical. We automate the matching of payouts to individual sales, track insertion and promotional fees, and manage the COGS entries to ensure you know your true per-item profitability.
Your E-Commerce Accounting Tech Stack
The right software stack turns chaotic transaction data into organized, actionable financial records. We recommend and use:
- Cloud Platforms: QuickBooks Online and Xero for robust bank feeds and multi-currency support.
- Marketplace Connectors: Tools like A2X or Webgility to pull settlement data directly into your ledger.
- Inventory Tools: Integrations with SOS Inventory or Dear Inventory for end-to-end stock visibility.
