The Real Problem

Your Sales Look Great.
But What’s Your Real Profit?

Revenue is easy to see. Actual profit hides behind landed inventory cost, Amazon and Shopify fees, returns, storage, and ad spend that never lands cleanly in your books. Most sellers are flying on a number that isn’t real — and generic bookkeepers make it worse.

  • Inventory bought but never costed against the right sales
  • Marketplace payouts booked as revenue — fees invisible
  • Ad spend nowhere near your true product margin
  • Sales-tax nexus quietly building across states
  • No idea which SKU actually makes money

How Korven Started

Born Inside Amazon.
Built on Finance.

Korven didn’t start as an accounting firm. It started inside Amazon accounts. Ahmed managed $5M+ in ad spend and $15M+ in inventory for brands at scale. He kept watching the same movie: sellers doubling revenue with no idea what they actually kept. Meanwhile his brother Azhar had spent 17 years fixing exactly that problem in US finance. So they stopped working separately. One firm. Operations and books under the same roof. Specialists in E-commerce and Real Estate. When we do your accounting, it isn’t theory. We’ve run your side of the business.

  • Amazon PPC management. Campaign architecture and bids tied to real margins. $5M+ managed by a senior specialist, not a junior with a dashboard.
  • Amazon supply chain management. Inventory planning and restock automation that killed stockouts across $15M+ of inventory. 99% in-stock.
  • Inventory finance. Reorder economics, cash-flow planning, and the real numbers behind every purchase order.
  • One firm, both sides. The operations and the books. Two brothers who built it together.

FAQ

E-commerce Accounting,
Answered.

Do you do bookkeeping for Amazon and Shopify sellers?+
Yes. Our ecommerce bookkeeping and ecommerce accounting services cover the full financial picture for online sellers — inventory and COGS, marketplace fees, sales-tax nexus, ad spend, and clean monthly books that show real per-product profit.
Why use an e-commerce specialist instead of a general bookkeeper?+
E-commerce finances break generic bookkeeping: landed inventory cost, marketplace payouts net of fees, multi-state sales tax, and ad spend all distort the P&L. We track them the way sellers actually operate, having managed $15M+ in inventory and $5M+ in ad spend ourselves.
Can you help with supply chain and inventory finance?+
Yes — proudly. Amazon supply chain management is where Korven started: inventory planning, restock automation, and cash-flow planning for reorders, proven across $15M+ of managed inventory at a 99% in-stock rate.
Do you manage Amazon PPC too?+
Yes. Amazon PPC management is part of our DNA — $5M+ in ad spend managed with campaign architecture and bids tied to real margins. And because we also run your books, your ACOS finally shows up where it belongs: in a real P&L.
