Launching an online store has never been easier. Standing up a storefront on Shopify or Squarespace takes an afternoon. Keeping one alive past the first busy season is the hard part, and it usually comes down to two things the setup tutorials skip: getting the legal and tax foundation right, and funding your inventory without strangling your cash flow. This guide covers both, from a Minnesota lender's seat.
What do you actually need to launch an online store in Minnesota?
Four pieces form the foundation, and none of them are the website.
First, choose and register a legal entity. Most Minnesota online sellers form a limited liability company through the Secretary of State, which separates personal and business assets and takes a single filing. Second, get a federal employer identification number from the IRS. It is free, takes minutes, and you need it to open a business account and hire anyone. Third, register with the Minnesota Department of Revenue for a sales tax account before you make your first taxable sale into the state. Fourth, open a business checking account and keep every dollar of the store's money separate from your personal finances. Clean books start on day one or they never start at all. A business checking account is the account of record your bookkeeping, your tax filing, and eventually your lender all rely on.
Skip any of these and you create a problem that costs more to fix later than it would have cost to do right at launch.
How do you handle Minnesota sales tax on online sales?
Sales tax is where new online sellers get surprised. Minnesota's state sales tax is 6.875%, and in the seven-county Twin Cities metro, local taxes add roughly another 1%, so a Minneapolis buyer may pay a combined rate near 8%. You collect that tax at checkout and remit it to the state on a schedule the Department of Revenue assigns you.
Selling beyond Minnesota adds a second layer. Since the 2018 Wayfair decision, states can require out-of-state sellers to collect their sales tax once the seller crosses an economic nexus threshold. In Minnesota, a remote seller triggers nexus at either $100,000 in gross retail sales or 200 separate transactions delivered into the state over a 12-month period, whichever comes first. Other states set their own thresholds. Most growing stores handle this with automated tax software that plugs into the storefront rather than tracking it by hand. The point is to set it up before you cross a threshold, not after, because the back taxes and penalties land on you.
What does it really cost to run an online store?
The website is cheap. The inventory is not. E-commerce is capital intensive in a way that does not show up in your top-line revenue: you pay for product, packaging, and fulfillment weeks or months before the cash from those sales lands in your account. Add a seasonal spike, and the gap between when you spend and when you collect can swallow a healthy-looking business.
That timing gap is the single most common reason a growing online store runs out of money while its sales are rising. Understanding it early is what separates the stores that scale from the ones that stall.

How do Minnesota businesses finance inventory and growth?
When you need capital, the structure matters as much as the amount. There are four financing tools most online sellers grow into, and each fits a different need. A working capital line of credit smooths the gap between buying inventory and collecting revenue, which is the seasonal cycle problem above. Inventory financing funds predictable, disciplined purchasing. A term loan pays for the durable investments, warehousing, fulfillment automation, or a technology upgrade, that raise your capacity. An SBA loan supports the larger moves, like an acquisition or a partner buyout. Our post on e-commerce financing breaks down when each one fits.
Here is why the structure matters, in numbers. Say your store needs $60,000 to buy inventory ahead of the fourth-quarter rush, and you will sell through it by January. A working capital line lets you draw the $60,000, pay it back as the sales come in, and pay interest only on what you use. Compare that to a fast online cash advance that takes a fixed slice of every day's sales until it is repaid. The advance is easy to get and brutal to carry: it pulls cash out on your slowest days as hard as your best ones, and the effective annualized cost often runs several times what a bank line would. The convenience is real. So is the price. Choosing the right loan structure is the difference between financing that funds growth and financing that eats it.
None of these figures are an offer, and every business is underwritten on its own cash flow, margins, and track record. If you want to know what a lender looks for, we have laid that out too.
When should you move from a side hustle to a real banking relationship?
The signal is not a revenue number. It is when the store stops being a project and starts being a business you depend on. That is when the separate account, the clean books, the right payment processing, and a lender who knows your operation stop being optional.
A community bank earns its keep here. When your payment processing and cash flow tools sit with a bank that also underwrites your growth line, the person approving your credit already understands your business. That is a different relationship than a national platform where you are a risk score. Security Bank & Trust works with online sellers across the Twin Cities and Greater Minnesota, and the banker who opens your account is the one who helps you grow it. That approach is part of why we are consistently ranked among Minnesota's top business banks.
Frequently Asked Questions
Do I need to register my online store as a business in Minnesota?
In most cases, yes. Most Minnesota online sellers form an LLC through the Secretary of State to separate personal and business assets, get a federal employer identification number, and register for a sales tax account with the Minnesota Department of Revenue before their first taxable sale.
Do I have to charge sales tax on online sales in Minnesota?
Yes, for taxable sales delivered to Minnesota buyers. The state sales tax is 6.875%, and the seven-county metro adds roughly 1% more. If you sell into other states, you may also owe their sales tax once you cross their economic nexus thresholds, which in Minnesota is $100,000 in sales or 200 transactions in a 12-month period.
How much money do I need to start an online store?
The storefront itself can cost very little. The real capital goes to inventory, packaging, and fulfillment, which you pay for before the sales revenue arrives. Plan for that timing gap, because it is the most common reason a growing online store runs short on cash.
What is the best way to finance inventory for an online business?
A working capital line of credit is the common fit, because it lets you draw funds to buy inventory and repay as sales come in, paying interest only on what you use. Inventory financing, term loans, and SBA loans each fit different needs as the business grows.
Should I use a bank or an online lender for my e-commerce business?
It depends on the cost and the structure, not just the speed. Fast online cash advances that sweep a share of daily sales are easy to get but often cost several times more than a bank line and pull cash on your slowest days. A bank relationship usually costs less and comes with a lender who understands your business.
Start with the foundation, not the storefront
The stores that last are not the ones with the slickest website. They are the ones built on a clean legal and tax foundation and financed with structure that fits the business instead of draining it. If you are launching an online store in Minnesota or scaling one past its first busy season, our business lending team can help you set up the banking and financing to grow on.
