What You Need Before You Open an Online Store

Opening a store is easy. Opening a store that can take money without creating refunds and support debt is a shorter list of unglamorous items. This article is that list. It is not legal advice, tax advice, or a recommendation of any platform.

If you still need the definition of the operating loop, start with What Is E-Commerce?. If you are choosing how you will sell, read E-Commerce Business Models Explained first, then come back.

The offer

Write one paragraph a stranger could use to decide:

• Who it is for (and who it is not for).
• What they receive (SKU, pack size, color, digital vs physical).
• What it is not (common mismatches).
• How long delivery takes in your primary shipping zone.

If you cannot write that paragraph, paid traffic will only buy you conversations you cannot close. Category pages and ads should inherit this language, not invent a second story.

Suppliers and inventory truth

You need a source you have actually used, or a documented first-order plan:

• Lead time from purchase order to goods-in.
• Minimum order quantities and whether you will hold stock or make to order.
• Who owns defective-unit risk.
• A reorder point that matches your sales velocity, not your optimism.

Dropshipping is a fulfillment method, not a skip-the-supplier method. If you have never received a sample, you do not know pack quality, insert cards, or dimensional weight—the things that set shipping cost and return rate.

For a first store, prefer fewer SKUs you can replenish over a scraped catalog you cannot stand behind.

Margin before merchandising

Price last is how stores launch into unprofitable volume. Price the SKU with:

• Landed cost (product + inbound freight + duties + packaging).
• Payment fees.
• Average outbound shipping you will not recover from the customer.
• Expected return/RTO share for that category.
• Marketplace or affiliate fees if those channels are in the plan.

Then set a selling price that still leaves contribution. Use the selling price calculator and check whether fixed costs (apps, pick-and-pack labor, a 3PL minimum) are covered with the break-even calculator. E-Commerce Profit Margin Explained walks through gross vs contribution vs net.

A common launch error is matching a competitor’s public price without matching their cost structure.

Legal basics as a checklist (not advice)

Confirm with a qualified professional in the places you sell. As an operator checklist, most stores need answers to:

Item	Why it blocks launch if missing	Typical owner
Business entity / registration	Who is the merchant of record	Founder + accountant
Tax registration and invoice rules	Checkout and invoices must match local rules	Accountant
Consumer / distance-selling rules	Refund windows, cooling-off, disclosures	Counsel
Product compliance	Safety, labeling, restricted categories	You + supplier docs
Privacy and payment data	You should not store card data yourself	Counsel + gateway
IP on photos and brand	You cannot use manufacturer assets you did not license	You

A theme’s “Privacy policy” generator is a starting draft at best. Publish policies you will actually follow. If you sell across borders, shipping promises and tax treatment change; do not copy a US template onto a different market and hope.

Photography and product facts

Customers buy what they can inspect. Before go-live:

• One consistent hero image per SKU (same background, same crop).
• Detail shots for texture, ports, stitching, or ingredients as relevant.
• A size or scale reference (model height, ruler, in-hand).
• A spec table: materials, dimensions, weight, what’s in the box, warranty length.
• Variant photos if color or size changes appearance.

Manufacturer copy is usually written for retailers, not for your URL. Duplicate descriptions across a hundred stores are a ranking and trust problem. See Product Page SEO.

Policies customers will look for

Put these where checkout and the footer can reach them:

• Shipping: zones, rates or calculator, cut-off times, what happens on failed delivery.
• Returns and refunds: window, condition, who pays return freight, exceptions.
• Payment methods: cards, wallets, COD if you offer it, and when the order is confirmed.
• Contact: a real path (email, form, or documented hours)—not only Instagram DMs.

COD vs prepaid changes cash flow and reverse logistics. If that is in your market, read COD vs Prepaid Orders before you enable it “to convert.”

Support you can actually staff

Assume a percentage of orders will ask “where is my order,” “wrong size,” or “payment deducted but no order.” Before you buy traffic:

• A mailbox or helpdesk that more than one person can see.
• Macros for the five questions you already know you will get.
• Access to tracking and payment status without screenshot archaeology.
• A returns address and a process for inspection.

Unstaffed support is a hidden COGS. It also feeds chargebacks, which cost more than a refund.

Platform is a later purchase

You still need a checkout, but you do not need to resolve Shopify vs WooCommerce before the offer is priced. Pick the stack when you know catalog size, who will edit products, and whether you need a specific payment or shipping integration.
