Selling on a marketplace or your own site does not create a new company type. The form, legal name, account and activity close before you sell.
Forming a company for e-commerce is not uploading a logo to a marketplace. Selling online does not create a new company type either. You form a sole proprietorship, a limited company or a joint-stock company. The marketplace account, your own site, or both, sit on top of that. The platform’s name does not choose the form. Your profit, whether you have a partner, and who is left with the debt do.
This is not the line-by-line list of formation papers. Those lists are in the guides to opening a sole proprietorship and setting up a limited company in Ankara. The question here is narrower: which decision has to be made before you sell, and which one, if you leave it until after the first orders, scatters the records.
Is e-commerce its own company type?
No. There is no company type called “e-commerce company” at the trade registry. A shop and a marketplace seller use one of the same three forms. The difference is where the goods go and which account the money reaches. The customer is at the end of a shipment, not at a counter. Collection usually lands first in the platform’s or the payment company’s account, and reaches you days later.
Money that lands in a personal account does not stop being income. It only tangles the bank record. The first sentence is not “which platform”. It is “whose account will the money reach”.
When does selling become a company matter?
Selling one spare household item through an ad, and sending parcels every week, are not the same thing. Regular, continuing sales are a commercial activity. This guide does not lock that line to a single turnover figure. Thresholds and exceptions change from year to year. The plainer question is whether you mean to keep doing this, or whether you are disposing of something once.
If you mean to continue, the tax plate is discussed before the sales. Orders taken first, with a company “later”, never receive a document. A platform panel is not an invoice.
Sole proprietorship or limited company?
E-commerce does not push this choice toward a limited company on its own. One person, with sales that are still small and uneven, often runs more simply as a sole proprietorship. A limited company comes into the conversation when there is a partner, when you want to grow a brand, or when you care about separating debt from personal assets. “It should look serious” is not, by itself, a reason. Seriousness is in the records.
Which form pays less tax does not close in one sentence either. A sole proprietorship can fit a low profit. A limited company can fit a growing one. The crossing point depends on income and expenses. That comparison is in sole proprietorship or limited company. This page does not repeat it. It only adds the three questions e-commerce puts on the table: whose name is on the returns address, whose legal name is in the platform contract, and which bank account receives the payout.
A marketplace usually asks for a tax plate and a legal name. Sole proprietorship or limited company is your decision, not the platform’s logo. The name on the application and the name on the plate have to match.
Decisions to close before you sell
The order below is the office’s suggestion from formation meetings. It is not an official formation regulation. If you skip a line, sales can still start. They start, and the first month’s documents arrive in a mess.
| Decision | What it is for | Where to look |
|---|---|---|
| What you sell | The activity description stays in the same sentence as the goods | The tax office list, not a code copied from a forum |
| Who is selling | One person, partners, or a brand owner only | The form comparison |
| Where the money lands | A business account, not a personal one | The bank, immediately after opening |
| Where returns go | Home, a warehouse, or an agreed returns address | The platform contract and the lease |
| Which document channel | E-archive and e-invoice are not the same obligation | E-ledger and e-invoice |
Leaving the returns address and the bank account for “later” ends with the first campaign paying into a personal account.

How should the activity be described?
The activity is not the single word “online sales”. What you sell is written down. Selling clothes while the activity says consulting makes a later invoice look unrelated. Write what you actually sell. The activity can be widened later. Narrow and accurate beats wide and random.
Do not copy an activity code from a forum. The code is chosen, on that date, from the tax office list for the goods you sell. A wrong code does not cancel the formation. It surfaces later, on a check or a return invoice. Choosing it while the papers are prepared is shorter than correcting it afterwards.
The brand on the storefront and the name on the tax plate do not have to match. The seller name in the contract and the name on the plate do. You can add the brand later. Correcting a letter on the plate later holds up the payment account.
What comes after formation?
A tax plate does not tidy sales on its own. The order below is the pile the office sees. It is not an official statistic. A longer bar means a more tangled first month if that step is skipped.
Steps that take the most care before you sell
The chart is the office’s suggested priority, not a count of hours. Who must use e-invoice is separated in the e-document guide. An order that leaves before that choice becomes a manual invoice queue.
Your own site and a marketplace do not require two companies. The same plate can carry two ways of getting paid, and both statements land in the same books. The monthly split is in e-commerce accounting. At formation, both channels are tied to the same legal name.
In the formation week, close the plate, the account and the legal name. Which screen a later VAT return uses is a separate question, covered in the VAT return guide.
Three mix-ups we keep seeing
The first is treating a personal listing and a trade as the same thing. One spare item is not a company. Goods supplied and shipped every week are not “just an ad”. The second is believing a limited company tidies the records by itself. The legal form does not match a commission invoice. The third is postponing the accountant for months. The first month’s documents pile up, and a pile is a more expensive correction.
Carrying the papers through is the work of company formation. The record after sales begin is accounting. Talking about both in the same meeting is fine. Treating them as the same job is not. A courier opening is not this guide either. The courier’s own steps are in how a courier sole proprietorship is opened.
Frequently asked questions
Do I have to open a limited company to sell on a marketplace?
No. A platform usually asks for a tax plate and a legal name. Whether the plate is a sole proprietorship or a limited company is your structure’s decision. If you have no partner, no brand plan and no need to separate debt from personal assets, a sole proprietorship can be enough.
Can I start selling and form the company later?
Not if you mean to sell regularly. Those orders never get a document. A panel export does not replace an invoice. An occasional personal sale and a parcel that leaves every week are not the same thing.
Do my own site and a marketplace need two companies?
No. The same legal name can carry two ways of getting paid. What is separate is the statement, not the company. Both statements land in the same books.
Is writing only “e-commerce” as the activity enough?
No. What you sell is written down. A code copied from a forum may not match the goods. The activity is chosen from the list while the papers are prepared.
Can I start with my personal bank account?
Income that lands in a personal account does not stop being income. The record gets tangled. Opening a business account right after formation is a cheaper job than the first campaign.
Is e-invoice mandatory as soon as the company is formed?
Not for everyone. Thresholds and sectors change. Who is obliged is separated in the e-document guide. This article does not lock a turnover figure.
Final word
Forming a company for e-commerce is choosing the right form and closing the legal name, the account and the activity description before you sell. The marketplace’s seller panel does not stand in for those three. The platform does not choose the form either.
At Ankara Muhasebeci we run this sequence from the Kızılay office, and remotely when a seller prefers that. The papers are discussed under company formation. The first month’s records are discussed as accounting. Not calling both “done” in the same breath keeps the first season calm.
