E-commerce Sellers in Florida Deserve Financial Systems Built for Online Business
NexusWorks LLC provides bookkeeping, sales tax compliance, and fractional CFO support for e-commerce brands operating out of Florida. We help online sellers gain financial clarity, lower tax exposure, and make sharper inventory decisions through a single integrated team rather than juggling separate vendors.
A single strong month can push Florida sellers over the nexus line before they notice
Amazon and Shopify payouts almost never match what was actually sold
Incorrect COGS calculations make margins look healthier than they really are
We also support e-commerce sellers in California, Texas, New York, Washington, and Tennessee.
Recurring Financial Problems Florida Sellers Run Into
Generalist accountants rarely keep pace with how e-commerce actually operates. The same handful of issues show up constantly:
Amazon redistributes FBA inventory across warehouses without notice, so sellers lose track of exactly which states carry a nexus obligation.
Platform settlements from Amazon and Shopify rarely match bank deposits, turning monthly reconciliation into a recurring project.
Landed cost, prep fees, and FBA charges get left out of COGS from the start, quietly inflating reported margin.
Florida requires direct sellers to register and remit separately from whatever Amazon already collects on marketplace orders, a distinction many sellers never realize exists.
Bookkeeping and tax planning operate in separate silos, so deductions get missed and quarterly estimates rely on outdated numbers.
Selling across multiple channels without one consolidated view leaves leadership guessing at actual monthly profitability.
None of this gets solved by a bookkeeper alone, or a tax preparer working in isolation. It takes one system watching everything together.
Why
Florida's Nexus Rules
Surprise Growing Sellers
A Threshold That Looks Simple But Isn't
Florida's economic nexus threshold is $100,000 in sales during the prior calendar year, with no transaction count involved at all. That simplicity hides a real trap: one unusually strong month, or a single large wholesale order, can push a seller over the line well before they expect it. Once a seller exceeds $100,000 in a given year, the obligation to register and collect begins automatically on January 1 of the following year, whether or not registration has actually happened yet.
FBA Storage Creates Physical Nexus Immediately
Storing inventory in a Florida fulfillment center creates physical nexus the moment it arrives, regardless of where the business is legally based. Amazon handles tax collection on marketplace orders, but direct sales through a Shopify store or website remain fully the seller's responsibility. Florida excludes marketplace sales from the seller's own $100,000 calculation, so direct-channel revenue needs to be tracked on its own rather than combined across everything.
Combined Rates Reach 8% Once County Surtaxes Apply
Florida's base rate is 6%, with counties layering on a discretionary surtax of 0.5% to 1.5%, pushing some areas as high as 8%. Because Florida sources tax based on delivery address, the applicable surtax shifts by county for sellers shipping st
The Department of Revenue Targets Sellers With Uneven Sales History
Florida's economic nexus rule has applied since July 2021, and enforcement has intensified against out-of-state sellers who cross the $100,000 mark without registering through Form DR-1. Because the rule uses a prior-year lookback with no transaction test, sellers with one high-revenue year followed by a quieter one are common audit targets, even after their current sales have dropped.
This isn't a tax explainer. These are specific risks your financial team should already be managing on your behalf.
How NexusWorks Supports Florida E-commerce Sellers
Full Reconciliation Across Every Channel
Every month, we match revenue, fees, refunds, and chargebacks from Amazon, Shopify, Etsy, and any other platform against your actual bank deposits. Reserve holds and mid-cycle payouts make this messy on their own we untangle it into financials that reflect real earnings, not platform noise.
Sales Tax Registration Tracked Against a Moving Threshold
We handle registration through Form DR-1 with the Florida Department of Revenue, calculate the correct county surtax for every delivery address, and file on schedule. Because Florida measures the $100,000 threshold against your prior calendar year’s direct sales specifically, we track that number continuously so the following year’s obligation never catches you by surprise.
COGS and Inventory Accounting Matched to Your Model
Whatever your fulfillment setup FBA, third-party logistics, in-house we structure inventory accounting around it. Freight, duties, and prep costs all factor into landed cost, so margins reflect what products genuinely cost to deliver.
Fractional CFO Support as Revenue Grows
Once a brand hits consistent revenue, the decisions get harder inventory buys, supplier terms, ad spend efficiency, cash timing. We handle the modeling: forecasting, inventory financing analysis, channel-level P&L, and reporting built for investors or lenders.

Frequently Asked Questions
Amazon's collection only applies to Amazon orders themselves. Sales through your own Shopify store or website are your responsibility, and Florida excludes marketplace sales from your own $100,000 threshold calculation, so direct sales need separate tracking. A CPA also manages income tax, COGS accuracy, and profitability reporting that Amazon's system never touches.
Immediately. The moment inventory is stored in a Florida fulfillment center, physical nexus exists regardless of sales volume. This applies independently of the $100,000 economic threshold entirely.
Bookkeeping is daily transaction recording, platform reconciliation, and expense categorization. Accounting builds on that into financial statements, tax strategy, and profitability insight. E-commerce sellers need both working together, since platform fees and inventory costs require treatment general bookkeeping typically misses.
Yes, fully. We connect directly to your platforms and bank accounts through QuickBooks, Xero, and secure portals, deliver monthly reporting, and manage every Florida and multi-state filing without requiring an in-person relationship.
We build landed cost starting with purchase price, then add freight, import duties, and prep fees, matching that total against monthly units sold for an accurate gross margin. Storage fees, disposal charges, and shrinkage are factored in too, so your P&L reflects what selling through Amazon actually costs.
