There are several ways to make money with printables, including:
Selling them on online marketplaces: Platforms like Etsy, Creative Market, and Society6 allow you to upload and sell your printables directly to consumers. This can be a great way to reach a wide audience and start generating sales quickly.
Setting up your own website: If you want more control over your branding and customer experience, you can set up your own website to sell your printables. This will require more work upfront, but it also offers more opportunities for scaling and monetizing your business over time.
Offering them as a lead magnet: You can use printables as a way to grow your email list by offering them as a free resource to people who sign up for your newsletter. Once you have a large email list, you can sell products or services to them.
Incorporating them into other products or services: You can also use printables to enhance the value of other products or services you're already selling. For example, if you're a coach, you might create a set of worksheets or a planner that you can sell to your clients as a companion to your coaching sessions.
Affiliate Marketing : if you have a audience or a following on social media or website you can make money by promoting the printable created by someone else and getting commissions.
Sponsorships: You can also make money by working with brands to create printables that align with their marketing objectives, which would include a fee or compensation for the creation of the printable.
Keep in mind that success with printables can be highly dependent on factors like the quality of your designs, your target market, and your marketing efforts. Additionally, these are not the only ways and the list is not exhaustive you can always come up with new ways
