Is there a way to change a vendor/customer to a contractor without having to delete vendor/customer and creating as a contractor?

There's no way you can change the vendor or customer to a contractor, mascon-contracto. Not to worry, I can share a workaround.

We can start with your vendor's profile. From there, select the Edit button at the top right corner to open the window where you can input their information. Scroll down to the Additional Info section and tick the Track payments for 1099 under the Taxes.

Once done, you can see your vendor under the Contractors tab. Payments made to them will be automatically reported to 1099 as they meet the annual $600 cash threshold, excluding payments made via credit card, debit card, or third-party system, such as PayPal.

Conversely, you'll need to create another profile for your contractor if you've initially set them up as a customer. However, using the same name is unapplicable as QuickBooks requires unique ones for customers, vendors, or employees. Therefore, consider adding a special character or any distinction.

Along with this is recreating all the transactions. Please make sure to use the correct expense account when mapping.

Additionally, here are a few resources to learn more about preparing 1099s:
