E-Commerce Accounting Services for US Brands
Multi-channel accounting is not general accounting. Marketplace settlements, SKU-level COGS, channel-scoped P&L, and post-Wayfair nexus tracking all break the standard playbook. Acgile runs the entire finance function for US e-commerce brands across Shopify, Amazon, Walmart, and WooCommerce, integrated natively into QuickBooks Online or NetSuite.
Delivered by dedicated teams at 40-60% below the cost of hiring in-house in the US, with a 3-5 day month-end close and no rotating freelancer pool.

Where multi-channel accounting breaks
Six pain points that generic bookkeepers miss
A general accountant can post transactions and close a month. E-commerce accounting is different because the operational data is fragmented across marketplaces, gateways, warehouses, and ERPs — each with its own reconciliation logic. Here is where books go wrong.
Marketplace settlement reconciliation is a black box
Amazon deposits net of referral fees, FBA fees, refunds, storage, ads, and coupon redemptions — often across two-week payout windows. Shopify Payouts do the same across gateway fees, chargebacks, and gift-card liabilities. Without a settlement bridge, the deposit in your bank account has no direct tie to the invoices that produced it, and revenue is chronically understated or misclassified.
COGS drift when one SKU sells across four channels
A single SKU can move through Shopify, Amazon FBA, Walmart WFS, and a 3PL — each with different fee structures, transfer timing, and settlement lags. Without SKU-level standard costs and channel-scoped fee mapping, gross margin becomes a blended fiction that hides which channel is actually profitable.
Multi-channel P&L opacity
The income statement shows a single revenue line and a single COGS line. But operations run four or more channels with different unit economics, ad spend allocation, and return rates. Executives fly blind on where to scale spend, where to cut SKUs, and which channel is quietly subsidizing another.
Sales tax nexus in 40+ states you didn't sign up for
Post-Wayfair, economic nexus triggers vary by state — $100K/200 transactions being the common floor, but many are lower or transaction-count only. Marketplaces file for you in most states, but nexus obligations for your direct storefront (Shopify, BigCommerce) do not disappear. Failing to track this creates back-tax exposure that surfaces during due diligence.
Inventory accounting the platform can't do
Neither Shopify nor QuickBooks Online handle real inventory accounting well — reserves, obsolescence, freight-in capitalization, standard-cost variances, and cutoff at period-end are all manual. Without a rigorous month-end inventory close, your balance sheet drifts and your gross margin swings a couple of percentage points every reporting cycle.
3PL billing leakage that AP will never catch
Standard AP reconciles 3PL invoices at the aggregate level. Systemic micro-leaks — DIM weight creep, phantom split-shipments, outdated zone tables, storage-snapshot billing — hide inside multi-page fulfillment payloads. Independent audits typically recover 2-5% of shipping spend. See our programmatic 3PL billing audit for the full teardown.
The scope
What we run for e-commerce finance teams
End-to-end scope of an Acgile e-commerce engagement. Take what you need — most brands start with bookkeeping and month-end close, then add inventory, marketplace reconciliation, KPI reporting, and EDI as they scale.
Full-cycle multi-channel bookkeeping
Daily transaction posting, categorization, and reconciliation across every marketplace, gateway, bank, and credit card. All bookkeeping happens inside your ERP (QBO or NetSuite) — no shadow spreadsheets.
3-5 day month-end close
Accruals, prepaid amortization, inventory cutoff, and full account reconciliation on a fixed cycle. Financials are review-ready by the fifth business day of the following month.
Accounts receivable & accounts payable
Invoicing, aging management, collections outreach, and bill-pay across your vendor stack. Bringing multi-currency and multi-entity discipline where needed.
Marketplace sync & settlement reconciliation
A2X, Amazon SP-API, Shopify Payouts, and direct settlement bridges. Every deposit maps back to the underlying orders, refunds, and fees so revenue and margin are actually accurate.
Inventory accounting & COGS
SKU-level costing (standard, weighted average, or FIFO), obsolescence reserves, freight-in capitalization, and rigorous cutoff so gross margin holds up under audit.
Executive KPI reporting
Unit economics, channel P&L, CAC and LTV, contribution margin, and cash-flow forecasting delivered on a monthly cadence — dashboards or PDF, whichever your board consumes.
EDI maintenance & retail chargeback defense
ASN/PO mapping, retailer compliance for Home Depot, Walmart, Target, and others, and dispute resolution when chargebacks fire. Keeps deduction leakage out of your P&L.

How our pricing works
Fixed-fee monthly retainer, not hourly
Engagements are scoped as a fixed monthly retainer covering a defined team, a defined close cycle, and a defined reporting cadence. You know the number before you sign, and it does not fluctuate with transaction volume within your normal operating band. Typical retainers land 40-60% below the fully loaded cost of a comparable in-house US accounting team (base salary, employer taxes, benefits, software, PTO, and management overhead).
No hourly billing surprises, no revenue-share on your top-line, no contingency fees for standard accounting work. Scope changes get re-scoped in writing before work starts.
