Scale Your Store.
Automate the Rest.
From Shopify to Amazon FBA. We untangle multi-currency transactions, cross-border sales tax, and complex inventory accounting so you can focus on driving traffic and growing revenue.

Sync Shopify, Amazon & Stripe seamlessly.
The Complexity of E-Commerce Accounting
High transaction volumes across multiple platforms and borders break traditional bookkeeping. You need a modern, automated tech stack.
Cross-Border Tax & Nexus
Selling into the US? Economic nexus laws mean you might owe state sales tax even without a physical presence. We monitor thresholds and handle multi-jurisdiction compliance.
Inventory & COGS
Cash spent on inventory isn't an immediate deduction—it sits on your balance sheet until the item sells. We implement proper Cost of Goods Sold (COGS) tracking to give you accurate margins.
Platform Reconciliation
Amazon and Shopify payouts are net of fees, refunds, and taxes. If you just log the bank deposit, your revenue is understated. We use middleware like A2X to reconcile every penny.

Automating Your Accounting Stack
Manual data entry is impossible when you process thousands of orders a month. We build a fully integrated, automated cloud accounting ecosystem for your brand.
The A2X Advantage
We utilize middleware tools like A2X to connect Shopify and Amazon directly to Xero or QuickBooks Online. Instead of importing thousands of individual transactions, A2X posts summarized journal entries that perfectly match your bank deposits. This ensures your gross sales, merchant fees, sales tax collected, and refunds are categorized flawlessly.
Multi-Currency Mastery
Buying from China in USD, holding inventory in Canada, and selling globally requires precise foreign exchange tracking. We set up automated multi-currency feeds so you always know your true profitability.
Unit Economics & ROAS Calculator
Analyze your true net margin per order and calculate your break-even Return on Ad Spend (ROAS).
You need a Return on Ad Spend of 1.85 to break even on your marketing dollars.
