Our StoryFrom eCommerce sellers to eCommerce accountants
TSA & COO Private Limited was founded by professionals who experienced firsthand the financial chaos of running an eCommerce business without proper accounting support.
We tried hiring general accountants. They didn't understand Amazon's fee structure. They couldn't reconcile Shopify payouts. They had no idea what sales tax nexus meant. So we built the firm we always wished existed — one that speaks your language and solves your actual problems.
Our Philosophy
Every decision we make is guided by one principle: your financial clarity is our business. We don't just file taxes — we help you understand your numbers, reduce your liability, and build a business that's financially bulletproof.
Our 100% Compliance Guarantee
If we make an error that results in a penalty, we pay it. Your financial safety is our responsibility — not yours.
TSA & COO by the Numbers
What Makes Us Different
We're not a generalist accountancy firm that happens to take eCommerce clients. We are eCommerce accountants. Period.
Platform-Native Expertise
Our team is trained on the specific fee structures, payout reports, and tax implications of every major eCommerce platform. We read Amazon settlement reports like other accountants read bank statements.
Cross-Border Specialists
Selling internationally? We manage US sales tax, UK VAT, EU OSS, and Pakistan FBR compliance simultaneously — with one dedicated team who knows the full picture of your business.
Proactive, Not Reactive
We don't wait for you to ask questions. We flag issues, spot opportunities, and reach out with relevant updates before problems become penalties. Your accountant should be working harder than you.
