Thank you for posting, @aia.
You can choose any scanners as long as it's a TWAIN-compliant.
After that, you'll have to set up and use QuickBooks Scan Manager so you'll be able to scan your documents and add them to your transactions, accounts, customer names, vendor names, employee names, other names, and inventory items.
These files will be saved in the same folder as your company file.
First, create your scan profile from the Company menu. Then, set up and test your scanner using the profile that you've created. Once all is successful, you can now scan and add documents.
To know more about this, check the following article: QuickBooks Scan Manager: Scan and attach documents to transactions.
Also, here are the answers to frequently asked questions (FAQ's) and recommended troubleshooting steps for common issues related to QuickBooks Document Center: QuickBooks Document Center: FAQs and common issues.
Let me know if you still have questions in setting up your scanner. I'm always glad to help in any way I can. Have a great rest of the day!
