Preparing your Sage file for a clean conversion

A short checklist that makes a Sage to QuickBooks conversion or a Quantum downgrade faster and trouble-free.


A little prep on your side makes a conversion or downgrade go smoothly and avoids a back-and-forth. Run through this before you send your file.

The checklist

  1. Make a fresh backup. Work from a backup, never the live file – see how to back up your Sage 50 file. US files produce a .PTB; Canadian files produce a .CAB.
  2. Confirm the backup restores. Open or restore it on your side first. A backup that won’t restore is the number-one cause of delays.
  3. Note your version and edition. e.g. “Sage 50 US Quantum 2023” or “Sage 50 Canadian Premium 2024.” The exact build helps us plan.
  4. Have admin credentials ready. We need the admin/sysadmin user and password for the file so our technician can open it.
  5. US Quantum downgrades: turn off SmartPosting. It runs in the background and can leave a file mid-post; disable it before backing up.
  6. Decide how much history you need. All of it, or the last few fiscal years? This shapes the scope of a conversion.
  7. List any add-ons or customizations. Custom reports, third-party integrations, or unusual workflows are worth mentioning up front.

What you don’t need to do

Ready

Once your backup is in hand, start a free evaluation and we’ll send a secure upload link. We reconcile the key reports against your originals before delivery, so the file you get back ties out to the one you sent.
