E-Commerce Sellers
Amazon takes a cut. Returns come back. Storage fees pile up. The deposit hitting your bank is a mystery. We solve it so you know what you actually made.
The Industry
The money showing up in your bank account is not your revenue. When Amazon deposits funds, they have already subtracted referral fees, FBA fees, storage charges, returns, and sometimes held reserves. Your Shopify deposits arrive after payment processing fees are taken. Each platform calculates things differently and sends different reports on different schedules. Looking at your bank account tells you almost nothing about how the business is actually performing.
Then there is inventory. You paid for those products months ago, but the cash outflow does not show up as an expense until you sell them. Your bank account looks healthy while inventory ties up tens of thousands of dollars. Or it looks tight because you just placed a big order for Q4, even though you are about to have your best sales month ever. Cash and profit are disconnected in ways that confuse most e-commerce sellers.
Who This Covers
Who This Covers
Shopify store owners, Amazon FBA and FBM sellers, Etsy merchants, dropshippers, subscription box operators, and multi-channel sellers working across several platforms at once.
The Friction
The Friction
Each platform has its own fee structure, its own payout schedule, and its own reporting format. Getting a clear picture of your business means pulling data from five different dashboards and reconciling it against bank deposits that do not match any of them.
What We Handle
We reconcile marketplace payouts back to actual sales. The gross revenue, the fees, the refunds, the adjustments. All of it broken out properly in your books. You see what you actually sold, what each platform took, and what landed in your account. This matters because decisions about pricing, products, and channels need to be based on real margins, not bank deposit totals.
Sales tax compliance is the other major piece. Economic nexus rules mean you might owe tax in states where you have never set foot but have exceeded sales thresholds. We track where you have nexus, handle the registrations, and file the returns. This is one of the areas where Leticia’s multi-state experience becomes particularly valuable. She managed compliance across dozens of states at a national pet pharmacy before starting Vast Accounting.
Platform Reconciliation
Platform Reconciliation
We connect to your Shopify, Amazon Seller Central, Etsy, and other platform data. Transaction-level detail flows into your books with fees properly categorized. No more guessing what Amazon actually charged you last month.
Sales Tax Compliance
Sales Tax Compliance
Nexus monitoring, state registrations, return filing, and remittance. Whether you have obligations in three states or thirty, the compliance work is handled so you can focus on selling.
What Goes Wrong
Most e-commerce sellers book their bank deposits as revenue. This understates your actual sales and hides the true cost of selling through marketplaces. A business doing $500,000 in actual sales might only see $420,000 hit the bank after fees. If you are tracking the deposits, your books show $420,000 in revenue and none of those fees show up anywhere. Your margins look higher than they are because you are not seeing the full picture.
Sales tax gets ignored until a notice arrives. States have become aggressive about pursuing e-commerce sellers who have exceeded nexus thresholds. The liability is not just for this year. It can include back years with penalties and interest. Some sellers discover they owe five figures in taxes they never collected. By then, you cannot go back and collect from customers. It comes out of your pocket.
Margin Confusion
Margin Confusion
You think a product makes 40% margin based on the purchase price and selling price. But after FBA fees, storage, returns, and advertising, the actual margin might be 18%. Without proper cost allocation, you do not know which products are winners and which are quietly losing money.
Nexus Exposure
Nexus Exposure
Every state has different thresholds. Some trigger at $100,000 in sales, others at 200 transactions. What you owed last year is not necessarily what you owe this year as your sales patterns change and you expand into new markets.
What Changes
You know your real numbers. Actual revenue, actual fees, actual margins by product and channel. When you are deciding whether to expand into a new category or pull back from a platform, the data is there to support the decision. Pricing gets smarter because you understand what you actually net after all the deductions.
The compliance burden lifts. Sales tax is tracked and filed on schedule. You are not wondering which states might send notices next month. Your books are ready for tax season, for bank financing, or for potential investors if that is the direction you are headed. Growth happens from a position of clarity instead of chaos.
