 MT Bachani CPA for Amazon, Shopify & Online Brands

E-commerce is not a traditional business.

It has layers of complexity — operational, tax, sales tax, accounting, inventory, and analytics — that most CPAs have never dealt with.

After more than 15 years inside e-commerce, from product research to selling on Amazon and Shopify, working with 3PLs, using Odoo, QuickBooks, and analytics tools like Power BI and Looker Studio, we see the same problem every day:

Regular CPAs do not understand how e-commerce actually works — and their clients pay the price.  

We Don’t Just Do Taxes — We Build Your Entire E-Commerce Financial Engine  


For e-commerce, tax prep is 10% of what you need. We do the other 90%, including:

  • Accounting cleanup
  • Monthly close
  • Odoo implementation
  • QuickBooks cleanup
  • Landed cost calculation
  • Multi-warehouse inventory
  • SKU profitability
  • Sales tax automation
  • Avalara integration
  • Power BI dashboards
  • Cash flow forecasting
  • KPI tracking
  • Entity & tax planning
  • Audit-ready books

Our goal is simple:

Clean data. Accurate books. Real margins. Smart decisions.

 We Understand E-Commerce Accounting the Right Way — Cash vs Accrual

Most CPAs insist on cash basis because it’s simple ;  But e-commerce requires accrual accounting to show the real picture:

But e-commerce requires accrual accounting to show the real picture:

Inventory paid months before sales ​
COGS must match sales, not cash outflow ​
Amazon holds payouts ​
Shopify/Stripe holds reserves ​
Ad spend benefits future sales ​
Subscriptions are constant overhead ​

Cash basis will ALWAYS distort your margins.  

We clean and convert messy Shopify/Amazon books into proper accrual, giving you accurate:

  • revenue
  • COGS
  • gross margin
  • profitability by SKU
  • actual net income

This is something most CPAs cannot do. 

We Simplify Multi-State Sales Tax Nexus with Avalara-Backed Expertise  

(We Are an Avalara Partner)

Most traditional CPAs still think:

“No physical presence = no sales tax.”

This is completely wrong.

E-commerce triggers economic nexus, and thresholds vary by state.

We handle:

  • Nexus analysis
  • Multi-state registrations
  • Avalara setup
  • Automated filings
  • Marketplace facilitator rules (Amazon vs Shopify)
  • Penalty prevention

Most CPAs don’t even check your nexus exposure — which can be a disaster.

  We Understand Amazon FBA, FBM, Fees, Reimbursements & Inventory Flows  

E-commerce operations include dozens of moving parts:

Amazon CPA :

  • Credit card fees
  • Amazon FBA & FBM fees
  • Amazon storage, removal & reimbursement cycles
  • Shopify fees
  • App subscriptions
  • Meta/Google/TikTok ad spend
  • Return costs & chargebacks
  • Packaging, shipping & fulfillment
  • Affiliate commissions
  • Influencer payouts
  • 3PL storage + pick/pack rates

If your accountant doesn’t understand these, they cannot produce accurate books.

We understand ALL of them because we’ve worked in e-commerce operations, not just tax.

We Understand Amazon Operations — FBA, FBM, Fees, Inventory & Reimbursement

Amazon is a world of its own, and most CPAs have never logged into:

  • Seller Central
  • FBA inventory reports
  • Reimbursement reports
  • Reserved inventory
  • Expected receipts
  • Stranded inventory
  • Settlement reports
  • Multi-channel fulfillment

Most CPAs don’t know:

  • Amazon sends replacement items to customers WITHOUT recording a sale
  • Amazon loses inventory and reimburses you differently
  • Amazon fees change per category, size, weight, and storage period
  • “Shipped revenue” and “settlement revenue” are different
  • Profitability must be tracked at SKU level

We understand Amazon inside-out — financially and operationally.

We Integrate 3PL, Shipping, and Warehouse Operations Directly Into Your Accounting

If your CPA doesn’t understand fulfillment, they cannot support your business.

We work daily with 3PLs and understand:

  • Receiving logs
  • Cycle counts
  • Shrinkage
  • Discrepancies
  • Pick & pack rates
  • Storage tiers
  • Returns and destruction fees
  • Multi-warehouse stock (U.S., Mexico, China, India)

This is essential for accurate COGS and inventory valuation.

We Build E-Commerce Tax Plans That Fit Your Inventory, Timing & Cash Flow

Tax planning for e-commerce requires DIFFERENT strategies:

  • When to buy inventory for tax savings
  • Whether to load stock in December or January
  • How to treat affiliate payouts
  • Proper deduction of subscription tools
  • When to convert to accrual
  • When to create an S-Corp
  • When to separate entities (brand / fulfillment / holding)
  • How to optimize nexus exposure
  • International seller considerations
  • How to structure influencer contracts
  • e-commerce tax planning

We tailor tax planning specifically for online sellers.

We Understand Every E-Commerce Platform and How Each One Impacts Your Financials  

Every Marketplace has unique challenges:

  • Shopify — refunds, abandoned carts, app fees
  • Amazon FBA — reimbursements, lost stock, category fees
  • Amazon FBM — shipping cost structure
  • Walmart — performance metrics & penalties
  • Etsy/eBay — listing fees, seller fees
  • BigCommerce/TikTok Shop — new analytics structures

Most CPAs treat all platforms the same.

We don’t — because they’re not.
