How to Start E-Commerce from Scratch: Step-by-Step Guide

The real obstacle to starting e-commerce is not technical — it is sequence. Most people research marketplaces before finding a product, think about ads before registering a business, and skip the “how much profit is left” question before setting a price. In this article we have laid the whole thing out end to end, in an order you cannot skip: from deciding what to sell, to legal setup, marketplace choice, payment and shipping infrastructure, pricing, and finally the profit tracking that makes all of it meaningful. We close every step not as a generic to-do list but through the eyes of a seller who protects their margin — because generating revenue is easy; having money left at the end of the month is a separate job.

Before you start: e-commerce is a margin business, not a sales business

The most expensive misconception among beginners is measuring success by revenue. “I sold 100,000 TL this month” sounds great but means nothing on its own; inside that revenue sit commission, commission VAT, shipping, returns, ads, packaging, and taxes. In e-commerce the winner is not the one who sells the most but the one who knows what is left from each sale. So read this guide with a one-sentence compass:

Short rule: If you do not know a step’s cost, you are not ready for that step. Choose the product, the marketplace, the shipping, and the price not with a “we’ll see later” but by their effect on net profit.

The seven steps below are ordered around that compass. Skipping a step does not make its cost invisible; it just means you see that cost at the end of the month, when you are not ready for it.

Step 1 — What will you sell? Niche and product selection

Everything begins with the product decision, and often it ends there too. A good starter product carries three qualities at once: there is demand (people are searching), competition is manageable(the first page is not jammed with giant brands), and the margin is healthy (profit remains after all deductions). If one of the three is missing, you have bought a problem, not a product.

Why narrowing the niche pays off

For a beginner, a “store that sells everything” is a bad plan. A narrow niche lets you reach your target audience with a smaller ad budget, negotiate better with suppliers, and look like an expert to customers. Instead of “home textiles,” think “nursery textiles”; instead of “phone accessories,” think “cases for a specific model.” As the niche narrows, competition falls and conversion rises.

Product traps to avoid

• Very cheap product: in the 40–60 TL band, shipping and fixed service fees eat most of the profit.
• Fragile/bulky product: high desi means high shipping; with glass or furniture, damage returns kill the margin.
• High-return category: size returns in apparel especially; the commission may come back but shipping usually does not.
• Hyper-competitive product: on a standard item everyone sells, your only weapon is price — and that drags margin to zero.

To understand what gets traction on Trendyol specifically and how its category logic works, selling on Trendyol is a good starting map. When choosing a product, hold not only “will this sell” but also “how many lira of profit is left” — we return to that second question with numbers in Step 6.

Step 2 — Company or tax exemption? Legal setup

With the product decided, the second choice is how you will sell legally. Selling on marketplaces in Turkey requires a tax identity: either an artisan/simple-basis exemption, a sole proprietorship, or a limited company. Which one fits you depends on your revenue expectation, cost structure, and growth plan.

The rough difference between the three paths

• Artisan / tax-exempt seller: under certain conditions suitable for low-volume, handcraft-heavy production; the lightest setup and bookkeeping burden, but with strict conditions and limits.
• Sole proprietorship: set up fast and cheaply, simple bookkeeping; the first choice for most people starting e-commerce. Progressive income tax as profit grows can be a downside.
• Limited company: higher setup and accounting cost, but tax advantages at high profit and limited liability; sensible if you have a growth or outside-investment plan.

The article sole proprietorship or limited company compares these three with numbers and scenarios and clarifies which is more advantageous at which revenue level. Opening a store on a marketplace also has its own costs; for the Trendyol case you can find them in the cost of opening a Trendyol store.

Honesty note: Tax and setup rules vary by personal situation and are updated from time to time. What is here is general information, not accountant advice — before any final decision, consult a certified public accountant and verify current thresholds/rates from an official source (the Revenue Administration, etc.). A wrong structure risks not a small slice of profit but the continuity of the business.

Step 3 — Which marketplace will you sell on?

Should you start with your own website or a ready-made marketplace? For someone starting from scratch, the practical answer is usually marketplace first. The reason is simple: a marketplace brings you ready traffic, payment infrastructure, and customer trust; you focus on the product and operations. Your own site is valuable long term for margin and brand, but building traffic and trust from zero at the start is tiring and expensive.

What to look at when choosing a marketplace

1. Category fit: which channel has strong demand for your product?
2. Commission and deduction structure: the same product leaves a different net profit on different marketplaces.
3. Payout period: how many days until the money reaches your account directly affects cash flow.
4. Competition intensity: how saturated is the first page for your product?
5. Operational load: shipping integration, return process, store-rating rules.

Though they all look alike, the commission and VAT model varies from channel to channel — for example, Trendyol calculates commission from the VAT-inclusive price and does not add VAT on top, while most marketplaces stack a separate 20% VAT on commission. To see which channel leaves more money for the same product, which marketplace is more profitable offers a step-by-step comparison. You are not forced to stay on one channel either; once a product settles in, the logic of expanding to multiple channels is in the multi-marketplace sales strategy. But first build a store that profits on one channel; scale is a multiplier of a profitable model, not a fix for a broken one.

Step 4 — Payment infrastructure and virtual POS

How you collect money depends on the channel. If you sell on a marketplace you do not need to set up a virtual POS; the marketplace collects the payment and you receive a payout on a set schedule. What matters here is not the POS but the payment calendar: money arrives not on the day you sell but on payout day, and the amount that arrives is not gross sales but the net after all deductions.

If you sell on your own website, you need a payment setup (a virtual POS or payment provider). The items you must compare here:

• Transaction commission: the percentage taken from each collection; higher on installments.
• Value date / payout period: how many days until the money reaches your account.
• Installment cost: do you or the customer bear the installment?
• Setup/fixed fee: is there a monthly or yearly fixed item?

Every POS commission on your own site comes straight out of your margin, just like a marketplace commission. So when setting the price, factor in from the start “what is left if the customer pays in 3 installments.” Whichever path you choose at the start, the rule is the same: collection is a cost item, and if you do not bake it into the price, profit comes out lower than you thought.

Step 5 — Shipping and logistics

Shipping is the item new sellers most underestimate. On a low-priced product especially, shipping is often a bigger cost than commission. There are two basic models:

• Marketplace contracted shipping: the shipment fee is deducted from your payout by desi, carrier, and any free-shipping campaign. It is easy to set up, and your bargaining power grows with volume.
• Your own shipping contract: once you reach a certain volume, a carrier you negotiate with directly can be cheaper; you receive the invoice straight from the carrier and this item does not appear on the payout.

Three profit-protecting reflexes in shipping

1. Measure desi upfront: the product’s real desi is the first number you need when pricing.
2. Calculate the free-shipping threshold: when you say “free shipping over 150 TL,” know who pays that fee.
3. Don’t forget return shipping: the return leg and repackaging of a returned item are costs too.

On the storage side you can manage from home or a small stockroom at first; as volume grows, the marketplace’s warehouse/fast-delivery programs come into play. But keep it simple at the start: few products, measured stock, known shipping cost. Locking money in stock is the cash trap beginners fall into most.

Step 6 — Pricing and profit margin

Now we reach the step at the heart of the guide. Every decision so far (product, channel, shipping, collection) meets in one place: the sale price. The right price is not your competitor’s price; it is the price at which you put your target margin on top of all your costs. Most beginners set the price as “competitor said 199, let me say 189” and, without realizing it, sell at a loss.

What makes up net profit on a sale?

After these items are subtracted from the sale price, what remains is net profit:

• Product cost (purchase + any customs/freight)
• Marketplace/POS commission (plus 20% VAT on top on most channels)
• Shipping fee
• Packaging and any service/transaction fee
• Ad share (per sale)
• 1% income tax withholding and the return share

A concrete example

Say you sell a product for 300 TL and your purchase cost is 150 TL. Let commission be 15%, shipping 35 TL, packaging 5 TL. Roughly: 300 − 150 (cost) − 45 (commission) − 35 (shipping) − 5 (packaging) = 65 TL gross; once the ad share, withholding, and return share come off, what remains shrinks further. Thinking “I sold for 300, bought for 150, so 150 profit” is exactly the revenue illusion this article warned about from the start.

Instead of doing this math by hand for every product and price, enter your purchase cost, sale price, commission, and shipping into the profit margin calculator and see net profit and margin instantly. The tool’s real power is that it runs in reverse: when you say “I want a 20% margin,” it back-calculates what price you need to sell at, so you set the price by your target margin, not by your competitor. To see how the VAT side loads onto the price as a whole, the e-commerce VAT guide is complementary.

Short rule: The competitor does not set the price — cost + target margin does. The only time you should go below your competitor is when your cost structure is genuinely better than theirs; otherwise, being cheaper is giving profit away.

Step 7 — Profit tracking and deduction control

You set the price right; the job is not done. Because even if the math looks nice on paper, the amounts actually deducted on your marketplace payout can differ from what you expected: a wrong commission rate, shipping deducted twice, a fee for a campaign you did not join, an extra service item. Profit is revealed not where you planned it but on the payout breakdown. So the seventh step is not a setup but a continuity: tracking the real deduction of every order.

A practical profit-tracking discipline for a beginner:

1. Expected profit: set the target net profit for each product in advance with the profit margin calculator.
2. Realized profit: read the actual deductions from the payout breakdown and compare with expected.
3. Variance analysis: examine the gap by product and line item; which deduction is breaking the plan?
4. Action: query the deduction that looks wrong with evidence, and dispute it if needed.

In the first months you can run this by hand with a spreadsheet; as product and order counts grow, manual tracking becomes impossible — and that is exactly the point where money starts leaking quietly. To go deeper on why and how to track profit systematically, calculating real profit on Trendyol is a good follow-up read.

The 5 most expensive beginner mistakes

• Mistaking revenue for profit: high sales plus loose math means losing money while growing.
• Pricing against the competitor: going below a rival without knowing your cost structure zeroes the margin.
• Forgetting shipping and commission VAT: on cheap products especially, these two eat most of the profit.
• Tying too much money to stock: cash locked in unsold product chokes the business early.
• Never checking deductions: a seller who does not read the payout breakdown never sees the over-deduction.

Frequently asked questions

How much capital do you need to start e-commerce?

There is no single number; it varies by product cost, initial stock quantity, channel, and ad budget. Starting on a marketplace with small stock and a limited product range requires far less capital than trying to pull traffic from zero on your own site. The healthy approach is to start with few products + measured stock + known cost, then grow the product that profits.

Can you do e-commerce without setting up a company?

Under certain conditions it may be possible within an artisan/tax-exemption scope, but the conditions and limits are strict and it does not fit everyone. This is entirely a personal tax decision — do not decide on general information; consult a certified public accountant and verify the current rule from an official source such as the Revenue Administration.

Marketplace first or my own site?

For someone starting from scratch, marketplace first is usually smarter; ready traffic, payment, and trust come to you. Your own site is valuable for brand and margin but is the next step. The two are not alternatives but sequential stages.

What should my profit margin be?

It varies by category and business model; the “right” margin is the one that keeps your business standing after all deductions and leaves room for growth. To see it in numbers, enter your own cost and price into the profit margin calculator and let it back-calculate the price you need for your target margin.

Conclusion: starting is the easy part, protecting profit is the hard part

Technically, starting e-commerce has never been easier than today; you can open a store in a few days and take your first order. The hard part is passing through commissions, shipping, ads, and returns month after month and actually keeping money from every sale. The seven steps of this guide are the sequence that gets you there; the last step, profit tracking, is the mirror that shows whether the others worked. Verimleexists precisely for that last step: once you track your sales, it reads the real deductions of every order from the payout breakdown, derives net profit per product, and alerts you when a deduction is larger than expected; for an item it judges unfair, it prepares a dispute draft — it does not automatically bring the money back, but it puts in front of you what was over-deducted and why, with evidence. You choose the product and build the channel; let the system track the deductions.

Currency note: The steps for starting e-commerce, tax and company obligations, and marketplace conditions change over time; this article is not a strict instruction but a general guiding reference. Verify tax and company matters with your own certified public accountant, and marketplace rules from the relevant channel’s official seller source. When you want to move with numbers, enter your own cost and price into the profit margin calculator and check your net profit against current conditions. This guide was reviewed on July 18, 2026.
