What's new in Sage 50 CA version 2021.1?

Welcome to the end of 2020! Our 2021.1 release is straightforward, no new features have been added.

Mega Note that you must install the 2021.1 update in order to print/e-file with updated T4, T4a, T5018, and RL-1 forms.

  • The Inbox traydownload for the 2021.1 version (update only*) is available on KB 108351.
  • The 2020.3 version download is also available on KB 102293 should you wish to stay on that version.

Resolved issues:

  • Our top resolved issue addresses the issue where in Sage 50 (Premium Accounting and higher) Auto Backup was locking the database, which interfered with using Remote Data Access and converting the company file. This has been fixed.
  • In Pro Accounting and higher, when creating a Trial Balance report with the option Net Changes for Period, bank deposit transactions are no longer missing from the report's For Period columns.
  • In Pro Accounting and higher, after processing an order with an inventory item and then changing the item number for that inventory item, any subsequent adjustment to the order will now properly affect the original item.
  • Related to the integration in Sage 50 Pro Accounting and higher,  if you processed an invoice in Sage Accounting and then turned off the regional tax for that invoice, you would get a generic error when downloading the transaction to Sage 50. The message has been improved to help clarify the steps needed to correct the problem.
