E-Commerce & Retail

Know your real margin — after platform fees, returns, and COGS.

E-commerce looks profitable until you do the math. Revenue comes in from Shopify, Amazon, Etsy, or your own store — but by the time you subtract platform fees, payment processing, returns, shipping, and the cost of the goods you actually sold, what's left? A lot of online sellers are growing their revenue and shrinking their margins without even realizing it. PrecisionPenny untangles multi-channel e-commerce finances so you always know where you actually stand.

Your Real Profit Margin — After Everything

Gross revenue is a vanity number in e-commerce. What matters is net profit after cost of goods sold, platform fees, shipping costs, returns and refunds, payment processing fees, and ad spend. Most sellers don't have a clear picture of this because their bookkeeping doesn't break it down properly. We set up your books to track every layer — so you know exactly which products are profitable and which ones are costing you money to sell.

–      COGS tracking — cost of goods sold matched against every sale

–      Platform fee reconciliation — Shopify, Amazon, Etsy, and others

–      Shipping cost allocation per order or category

–      Returns and refund recording so your revenue numbers are accurate

–      Ad spend tracked as a true cost of sale

Multi-Channel Reconciliation — One Clean Set of Books

Selling on three platforms means three different payout schedules, three different fee structures, and three different reporting formats that all need to be reconciled into one accurate set of books. This is where most e-commerce bookkeeping falls apart. We connect all your sales channels to QuickBooks, reconcile every payout, and give you a single source of financial truth — regardless of how many platforms you sell on.

Inventory Management & COGS

Inventory is an asset until it's sold — at which point it becomes a cost. Tracking this properly is one of the most important and most commonly mishandled aspects of e-commerce bookkeeping. Mismanaged inventory accounting inflates your profit, distorts your tax liability, and makes it impossible to know your true business value. We set up proper inventory tracking so your financials reflect reality.

Sales Tax Across Multiple States

If you're shipping to customers in multiple states, you may have sales tax obligations you're not aware of — or not collecting correctly. Economic nexus rules mean you can trigger a filing requirement simply by selling enough volume into a state, regardless of where you're based. We track your sales by state and flag when you're approaching nexus thresholds so you're never caught off guard.

Know Which Products Are Actually Worth Selling

When your books are set up correctly, the data tells you things you can't see otherwise — which SKUs have the highest margins, which product lines are dragging down your average, and where you should be focusing your ad budget. PrecisionPenny turns your financial data into a decision-making tool, not just a compliance requirement.
