I am currently using NAPS2.  it can be found at www.naps2.com

it is compatible with WIA and TWAIN scanners.

it will save to PDF, TIFF, JPEG, PNG and other file types.

I use the PROFILE settings to enable auto save to a folder with a default file name that includes year, month, day and scan number.  I save it to a folder in the QBDocs\attach\ and a specific sub folder. I sort the folder by date descending.

The profile can be associated with an Fn key on the keyboard and be set up clear the iamges from NAPS2 after saving.

I am a contractor and use this heavily in CHECK ENTRY and BILL ENTRY.

After scanning (or while it is scanning) the document I click on the ATTACH FILE button in my QB app (like WRITE CHECKS) and then COMPUTER as the source.  This appears to always to default to the last folder used (in my case I use a folder named MISC RECEIPTS).  I the select the top item in the folder (the one i just scanned) and complete the attachment process.

This is not horribly different from the now deleted feature we lost.  It really uses a similar auto file naming process but does lack the searchable fields (which I have never used in actual practice)

With a little pre-planning you can set this up by user in the folder structure (are you using data files on each user computer or a central data structure?) and define multiple NAPS2 scan profiles for different QB tasks (I use write checks, bill entry, add instructions and installation documents to customer jobs to name a few).

I used to be in Manufacturing and System Software Sales and started doing this 25 years ago.

Hopefully this helps.
