Almost always yes. But the reason most people give for it is wrong, and it leads them to the wrong conclusion three months later.
The usual reason is “to test whether it works.” That test cannot be run, because the comparison is unfair by construction. A marketplace listing sits inside an existing stream of buyers. A new store sits in silence. Comparing them tells you which one has traffic today, which you already knew.
So a store you open early will make very few sales, and that is the expected result rather than the answer to anything. If you treat it as a verdict, you close the store and conclude the marketplace is the only option, having learned nothing.
Open one anyway. Just measure something else.
What It Is Actually For
Three things, and none of them are revenue.
Learning the operational work while you still have income
This is the strongest argument and the least discussed. Running your own store means owning the parts the marketplace was quietly doing: payment processing and its failures, tax handling, shipping labels and rates, refunds, chargebacks, the email that has to go out when something is out of stock, and the customer who wants to know where their order is.
None of that is hard. All of it takes longer to get right than anyone expects, and every hour of it is an hour you are not making or selling.
Learning it under no pressure, with a handful of orders, while the marketplace still pays your bills, is a very different experience from learning it in the month after you switched off your only income.
Starting the assets that take longest
Some things cannot be rushed at the end, and they are precisely the ones that decide whether a store works.
An email list. It compounds and it is yours. Every month you do not have one is a month of buyers you cannot reach again.
Indexed content. Search engines take time to find, crawl and trust a new site, and there is no version of that process you can compress into the two weeks before you leave.
A domain with some history behind it.
Whatever you learn about which products sell on their own merits, rather than because a marketplace search put them in front of someone.
Starting these early costs almost nothing. Starting them late is the reason a lot of exits look like a cliff.
Finding out whose customers they actually are
This is the uncomfortable one, and it is the single most valuable thing the parallel period tells you.
Some of your buyers came for you. Some came for the marketplace and you happened to be the result. Those are two different businesses and only one of them survives a move.
A store running alongside gives you a real answer, because you can see who follows a link, who joins a list, who buys again somewhere that is not the marketplace. That number is the one that predicts your exit, and it is why is it too early to leave turns on repeat buyers rather than on revenue.
The Cost, Stated Honestly
Running both is not free, and the cost is not the store subscription.
It is your attention, and it does not split evenly. The marketplace side pays now, so it gets the urgent work. The store side pays later, so it gets whatever is left, which in a busy month is nothing.
The predictable failure is a store that exists, has three products on it, has not been touched in two months, and quietly convinces you that your own site does not work. It was never given a chance to.
If you cannot commit some regular time to it, opening it early is worse than not opening it, because the dead store becomes evidence for the wrong conclusion.
Set the Right Success Criteria Before You Start
Decide these in advance, because deciding after the fact is how a working experiment gets read as a failure.
Good measures for a parallel store:
- Can you fulfill an order end to end without looking anything up?
- Do you have an email list, and is it growing at all?
- Has anything been indexed and found through search?
- Have any repeat marketplace customers bought from you directly?
- Do you know your real per-order cost outside the marketplace, including payment fees and shipping?
Bad measure: monthly revenue compared to the marketplace. It will be worse for a long time. That is not information.
Check the Marketplace’s Rules First
Before you do anything, read your marketplace’s current policy on directing buyers off-platform. Marketplaces generally restrict soliciting sales elsewhere, and the specifics differ by platform and change over time.
This is worth being precise about rather than guessing at, because the penalties land on the account that is currently paying you. Selling on both platforms is normally fine. Using one to advertise the other frequently is not. Where exactly that line sits is a question for the platform’s own current terms, not for any article.
The practical consequence: build your list and your audience through channels you own or that are neutral, rather than through marketplace messages and package inserts, until you have checked what is permitted.
When Not to Open One Yet
When you have no time at all. A neglected store is worse than none.
When the product itself is not settled. If you are still working out what you sell, a second storefront multiplies that uncertainty rather than resolving it.
When the marketplace business is in trouble. Fixing what pays now comes before building what might pay later, and a parallel store is a poor rescue plan for a shop that is currently failing.
A Reasonable Shape for the Parallel Period
Open small. A handful of your best products, not the whole catalog. The catalog can move later, and maintaining two full listings is a real burden.
Give it a fixed slot. A few hours a week, on the calendar. Not “when there is time.”
Run it long enough to mean something. Several months, not several weeks. Search visibility and list growth do not report back on a short timescale.
Then read the numbers you chose at the start, not the revenue comparison. Whether the move makes sense at all, and what it changes structurally, is the subject of should I move from a marketplace to my own store.
The Short Version
- Yes, open one. No, you cannot test it against the marketplace. The comparison is rigged and low sales prove nothing.
- Its real jobs are operational practice, slow-building assets, and finding out which customers are yours.
- The cost is attention, and the marketplace will win that contest unless you protect the time.
- Choose your measures before you start, and do not let revenue be one of them.
- Check the platform’s rules on off-platform selling first. The penalty lands on the income you still need.
