Retail, E-commerce & SaaS Accounting

That Grows With Your Sales

Selling online is fun—until spreadsheets, sales tax rules, and payout reports start piling up. At PCS, we make e‑commerce accounting simple so you can stay focused on what you do best: building your brand and growing your sales.

We connect your online stores, payment processors, and inventory tools into one clean financial dashboard, giving you real-time clarity on cash flow, profit, and performance across every channel.

From Clicks to Clarity

Whether you sell on Shopify, Amazon, Etsy, or your own site, PCS helps you stay organized, compliant, and profitable.

Our Montréal-based, bilingual team blends cloud accounting, automation, and CFO‑level insight to give you a true picture of your online business—from the first click to money in the bank.

How PCS Helps E‑Commerce Businesses Grow Smarter

1.

Smart Inventory and Cost Control

See what’s in stock, what it costs, and what it earns you—without guesswork. We track inventory, COGS, and product margins in real time so you can price confidently and avoid stockouts, dead stock, and cash-flow crunches.

2.

Multi‑Region Sales Tax Compliance

We handle GST, QST, HST, PST, and international taxes so you stay compliant across provinces, states, and countries. Automated systems flag what you owe and where you owe it, helping you avoid year‑end tax surprises.

3.

Clear Cash Flow Forecasting

Online revenue can spike one week and dip the next. We map out future inflows and outflows so you can plan promos, purchase inventory, and manage payables without stressing over your bank balance.

4.

Reconciliation Across Platforms

Selling on multiple channels? No problem. We reconcile sales from Shopify, Amazon, eBay, Stripe, PayPal, and more, making sure your platform reports, bank deposits, and books all line up.

5.

E‑Commerce‑Ready Financial Reporting

You’ll get investor‑ready financials that break down results by channel, product, and campaign. Quickly see what’s working, what’s not, and where to double down for more profit.

6.

Strategic Pricing and Margin Analysis

We dig into costs, shipping, fees, and discounts to find hidden profit leaks. Then we help you fine‑tune pricing and promotions for healthier margins and sustainable growth.

7.

Refunds, Returns, and Discounts Simplified

Returns and promos are part of selling online—but they shouldn’t wreck your books. We handle refund accounting and promotional adjustments so your numbers stay accurate even when sales surge or returns spike.

8.

Subscription and Deferred Revenue Management

Running a subscription, membership, or box model? We make sure revenue is recognized properly, so your financials show the full story—not just this month’s cash.

9.

Audit Readiness and Tax Optimization

Our systems keep you audit‑ready all year, while our team looks for legitimate deductions and credits to help reduce your overall tax bill.
