If you don't have a business registration yet
Most marketplace seller signups require some form of business registration or tax ID. If you have not registered a business yet, getting that in place first will make the rest of the signup process much smoother. Requirements vary by country, so check your local rules.
Compare against other channels
It is worth checking the signup process for a couple of different marketplaces side by side, so you can compare which one is likely to fit your product before committing your time to one platform.
Frequently Asked Questions
Can an individual, not a registered business, sign up as a seller?
Some marketplaces do allow an individual seller path, but once sales volume grows, formal business registration is usually required. Many sellers register a business from the start for this reason.
How long does the review take?
It depends on the documents submitted and how busy the review queue is; missing or mismatched documents typically add delay. Check the seller portal or your notifications for the current status.
