e-Commerce CPA

Running an e-commerce business today means dealing with Amazon fees, Shopify payouts, multi-state sales tax, 3PL logistics, constant content creation, and competitors changing every day. Most sellers still don’t know their real profitability, COGS, or customer behavior because their systems—Amazon, Shopify, QuickBooks, Odoo, NetSuite, ShipStation—never match.

At MT Bachani CPA, we fix this chaos. We give online sellers accurate books, true margin clarity, tax compliance, and a clean financial system that finally makes sense.

 What Our eCommerce Accounting & e-Commerce CPA Services Deliver

We organize the entire financial side of your eCommerce business — from COGS to sales tax to dashboards — so you finally have one clear, accurate picture of your true profitability.

Amazon FBA warehouse inventory for e-commerce COGS and profitability analysis

True COGS & Product Profitability

Most sellers don’t know their true product cost.

We calculate real COGS including manufacturing, freight, duties, 3PL fees, Amazon/Shopify fees, packaging, and returns — so you can see SKU-level profitability with accuracy.

Digital advertising dashboard showing ROAS and marketing ROI for e-commerce brands

Advertising Cost & Marketing ROI Analysis

Ad spend without clarity kills profit.

We connect your Meta Ads, Google Ads, Amazon PPC, TikTok Ads, and influencer spend to actual sales… giving you real ROAS, MER, CAC, and contribution margin.

ERP system integration for centralized e-commerce financial and operational data

Centralized Financial & Operational Data

Your data is scattered across Amazon, Shopify, QuickBooks, Odoo, NetSuite, ShipStation, and dozens of apps.

We integrate your systems and bring all numbers into one clean source of truth — no more spreadsheets or mismatched reports.
