Keep your budget in mind when choosing your online store builder. If you are building your first store, you may look at the cheaper options to save money, but does it have all of the key features you need? Will the platform you choose allow you to scale and monetize from your business as it grows in the future? If you choose to expand your business into different platforms, which takes time and money, then you need an online store builder that can accommodate this.
Remember, choosing an online store builder is an investment in your business, so take your time to find the one for you!
