Adding products and services to 17hats one at a time works fine for a handful of items, but if you're building out a full catalog or updating dozens of entries, there's a faster way. This tutorial walks through bulk importing products and services with a CSV file: downloading the template in Account Settings, filling it out in your spreadsheet app of choice, and uploading it back into 17hats. We'll cover why your accounting categories need to already exist before you import, what those checkbox headers ending in yn mean, and how to preview and select items before the upload finalizes. We'll also touch on duplicate entries and why you'll want to think twice before deleting anything once it's in your account.
