Running a product-based business on Shopify or other eCommerce platforms means more than just tracking sales—it’s about understanding your margins, managing inventory efficiently, and building a scalable, profitable brand. At First Tax Service, we specialize in eCommerce accounting and Shopify advisory services for founders who want more than just clean books—they want real strategy.

Led by financial advisor Anh Nguyen, we serve online retailers, DTC brands, and content creators with product lines who need more visibility into their financials. Our team helps you set up smart systems, clean up messy data, and stay ahead of tax, inventory, and cash flow complexities—so your numbers actually guide your growth.

Shopify Sellers, We've Got You Covered

If you’re building a brand on Shopify or selling across multiple channels (Amazon, Etsy, Klaviyo, etc.), your business model demands an accounting partner who truly understands the eCommerce ecosystem.

From beauty products to apparel, digital goods to subscription boxes, we’ve helped online sellers clean up their backend, make smarter decisions, and grow sustainably. We also assist in choosing the right tech stack—like A2X, QuickBooks Online, and inventory tools—to keep things running smoothly.

Financial Strategy for E-Commerce Entrepreneurs

We know that eCommerce moves fast—and your numbers need to keep up. With our Shopify accounting services in San Jose, you’ll get financial reports that actually reflect what’s happening in your business. We help you identify your top-performing products, reduce unnecessary spending, and get a clear view of profitability across SKUs, channels, and campaigns.

Whether you're launching your first line or hitting 8-figures, our approach is flexible and built to grow with you. And because we offer full-service support—bookkeeping, tax planning, accounts payable, and fractional CFO—you get more than data. You get a strategic financial partner.
