Ecommerce Platform FAQ: Costs, Setup, Taxes and Switching
Straight answers to common questions about ecommerce platforms in the U.S., including costs, free plans, LLCs, sales tax, payments, SEO, support, and when to upgrade or switch.
This guide answers the questions U.S. sellers ask most often when comparing ecommerce platforms. The short version: total cost matters more than the plan price, you can start small and upgrade, sales tax needs attention early, and a short trial with real products is the best way to choose. Details change by provider and state, so confirm important points on official or provider pages. The answers below are general information, not legal, tax or financial advice.
Costs and pricing
How much does it cost to run an online store?
It depends on the platform type, your volume and the apps you add. A simple hosted store has a subscription, payment fees on each sale, a domain and possibly a few paid apps. Open-source stores shift costs to hosting and developer time. Use the monthly cost calculator with your own numbers, and read what affects ecommerce platform cost.
Are there truly free ecommerce platforms?
Some software is free to download, and some services have free tiers, but you usually pay for something: hosting, payment fees, premium features, a domain or developer time. Look for the cost that appears once you take real orders.
Why are payment fees charged even if I do not sell much?
Fees are mostly per transaction, so they only appear when you sell. Monthly fees, however, apply regardless. Check the fee schedule for monthly minimums, statement fees and PCI charges.
Is it cheaper to pay annually?
Often, but you pay upfront and may not be able to get unused time refunded. Try monthly first.
Setup and legal
Do I need an LLC?
Not required to sell, but an LLC or corporation can separate personal and business liability. Talk with an attorney or accountant about your situation and state rules.
Do I need an EIN?
Many sellers get one. It is free from the IRS and keeps your Social Security number off business forms.
Do I need a business license?
Often at the state or local level. Requirements depend on location and product. Check your state business portal and city website.
Can I run the store from home?
Usually yes, but check zoning, home-occupation rules and lease or HOA restrictions, and consider business insurance.
Sales tax and income tax
Do I charge sales tax to every customer?
No. You charge it where you are registered and required to collect. Rules depend on nexus. See sales tax for online sellers.
Does a marketplace collect tax for me?
For sales on that marketplace, usually yes under marketplace facilitator laws, but not for sales on your own site.
Will I get a tax form from my payment provider?
Possibly, such as Form 1099-K when federal reporting thresholds are met. Thresholds have changed in recent years, so check the IRS for current rules. All income is reportable whether or not you receive a form.
Payments and risk
What payment methods should I accept?
Major cards and the digital wallets your customers use, plus any methods typical for your audience. More options can raise conversion but may add fees.
Why was my payout delayed?
New accounts and sudden volume spikes can trigger reviews or reserves. See chargebacks and account holds.
Do I need PCI compliance?
Yes, anyone who accepts cards must meet PCI DSS requirements. Hosted checkout reduces the burden, but you may need to complete a questionnaire.
Choosing and switching
How do I choose between platforms?
List requirements, shortlist two or three, build test stores and compare total cost, features, support and data portability. See choosing the right ecommerce platform.
When should I upgrade my plan?
When the savings in fees or the value of features exceed the added cost, or when limits on staff, inventory or reports slow you down.
When should I switch platforms?
When total cost, missing features or performance consistently hurt the business and the savings or benefits repay the migration cost. Test with the migration payback calculator.
Will switching hurt my SEO?
It can cause fluctuations, but redirects, preserved content and consistent URLs reduce risk. See migrating ecommerce platforms.
Marketing and operations
Do I need to spend on ads?
Not necessarily, but most new stores need a plan to find customers, whether through search, email, social media or marketplaces. Start small and track results.
How do I handle returns?
Publish a clear return policy, process refunds promptly and track reasons for returns to improve products and descriptions.
How do I know if my store is legitimate to customers?
Show real contact details, clear policies, secure checkout and honest product information.
