The cost to start an online store splits into four buckets: platform and tools, product and inventory, getting found, and the costs nobody warns you about. The first bucket is small and predictable. The second is where almost all the money goes, and it varies enormously by model. The third is ongoing and unavoidable. The fourth is what causes people to run out of money earlier than they planned.
This article lists the actual line items so you can build a real budget instead of a hopeful one. It does not give you a single headline figure, because the honest answer depends entirely on which model you pick — and a made-up number would only mislead you.
Bucket 1: Platform and Tools (Low and Predictable)
These are the costs of having a store at all. They are the ones people research most and worry about most, and they are usually the smallest part of the total.
- Domain name — annual, cheap, renews.
- Store platform subscription — monthly, or a marketplace seller account fee, depending on where you sell.
- Hosting, if you run a self-hosted store rather than a hosted platform.
- Theme or template, one-off, or free depending on platform.
- Essential apps or plugins — shipping rates, reviews, email capture, tax calculation. Each is small; five of them are not.
- Business email — monthly per mailbox.
- Business registration — one-off, varies by jurisdiction.
- Accounting software — monthly, and worth having from day one.
- Payment processing setup — usually free to set up, charged per transaction.
The practical advice here: start with the minimum and add tools when a specific problem appears. Subscription creep is real, and a stack of apps you selected before you had customers is a stack chosen for problems you do not have.
Bucket 2: Product and Inventory (Where the Money Actually Goes)
This bucket is almost entirely determined by your business model, so budget it by model.
| Cost line | Dropshipping | Print on Demand | Private Label / Wholesale |
|---|---|---|---|
| Samples | Small — a few units | Small — a few blanks | Meaningful — three suppliers, multiple rounds |
| Initial inventory | None | None | The largest single line in your budget |
| Freight and duty | Supplier-handled | Partner-handled | Yours, and often underestimated |
| Packaging and inserts | None | Partner-handled | Yours, per unit plus setup |
| Product photography | Supplier images, usually weak | Mockups | Yours — product, lifestyle, detail |
| Warehousing or fulfilment fees | None | Per-order | Per-unit storage plus pick and pack |
| Compliance testing or documentation | Supplier-dependent | Low | Category-dependent, can be substantial |
Two lines deserve a warning.
Freight and duty. The quoted unit price from a manufacturer is not your cost. Freight, customs duty, port and handling charges, inbound shipping to your fulfilment location, and per-unit packaging all land on the same unit. Work out your landed cost per unit before you treat any margin as real.
Photography. If you are selling your own branded product, supplier photos will not do. Either budget for a photographer or budget the time and basic equipment to do it yourself. This is not optional spending; thin imagery is one of the most reliable ways to lose sales.
Bucket 3: Getting Found (Ongoing, Not One-Off)
A store with no traffic makes no sales, so this is a cost line from the first week, not something you add later.
- Paid advertising, if your margin supports it. Treat your first spend as research, because it is: you are paying to learn which audience and which creative works.
- Content production — your own time, or a writer’s.
- Email platform — usually free at low subscriber counts, then monthly.
- Sample product for reviewers or affiliates, if that is part of your plan.
- Marketplace advertising, if you sell on a marketplace where sponsored placement is how new listings get seen.
The honest way to budget this is per month, not as a launch cost. Pick a monthly number you can sustain for several months, because a single month of spend rarely tells you anything conclusive.
Bucket 4: The Hidden Cost to Start an Online Store
These are the ones that break budgets, because they are invisible until they arrive.
Payment processing and marketplace fees. Per-transaction percentages plus fixed fees. On low-priced items the fixed portion matters more than the percentage.
Returns and refunds. You usually refund the full price including the shipping you paid, and the returned unit may not be resaleable. Apparel and anything with fit or sizing runs higher.
Chargebacks. Each one costs the order value plus a fee.
Sales tax, VAT or GST. Registration thresholds, filing obligations and the software to calculate it correctly. Research the rules for where you sell before you sell, not at year end.
Storage fees that rise with slow stock. Inventory that does not move costs money to keep sitting still, and some fulfilment programmes charge more the longer it stays.
Replacing defective units. Build an allowance into your per-unit maths rather than treating every defect as a surprise.
Your own time. Not a cash cost, but the real one. A store takes consistent hours. Costing your time at zero is how people conclude a thin-margin product is viable.
How to Budget the Cost to Start an Online Store
- Pick your model first. Dropshipping, print on demand, private label and wholesale have fundamentally different cost shapes. Budgeting before choosing produces a meaningless number.
- List every line above that applies to you and put your own researched figure beside it. Get real quotes — platform pricing, freight estimates, fee schedules — rather than estimates from memory.
- Separate one-off from monthly. You need two totals: what it costs to open, and what it costs to run each month with no sales.
- Calculate your landed cost per unit, including freight, duty, packaging and an allowance for defects and returns.
- Add your fees per sale — payment processing, marketplace referral, fulfilment — and work out your actual net margin per unit.
- Multiply your monthly running cost by the number of months you can fund it. That is your runway, and it is the number that determines whether this is a business or a deadline.
Where to Spend and Where to Save
Worth spending on: samples and a second round of samples, product photography, and accounting from day one. Each of these prevents an expensive mistake rather than creating a nice-to-have.
Worth delaying: a custom-designed store, a large app stack, branded packaging inserts, and any tool solving a problem you have not yet encountered. These are all upgrades that make more sense once something is selling.
Worth doing yourself at the start: copywriting, customer service and basic photography. You learn things from each of them that you will never get from a report.
One Number You Should Write Down Today
Before you spend anything, write down the amount of money you can put into this and genuinely be prepared to lose. Keep that figure separate from your savings and your living costs. Then build a plan that fits inside it. That single discipline prevents the most common and most damaging mistake in starting a store, which is finding out you are out of money in the middle of learning what works.
