The conversion procedure in Sage allows you to convert QuickBooks data from up to three years previous. However, it does sometimes get tricky to convert QuickBooks file to Sage 50. This is why we have compiled this guide. 

If you need to switch to Sage for detailed job costing, clear audit trails, local data control, unlimited users, and premium features, you are in the right place. In this article, we explain what you need to plan and prepare before you migrate to Sage and walk you through the steps.

Why the Switch – How Does Sage Compare to QuickBooks?

There are plenty of reasons you might want to switch to Sage 50 after your arduous years doing QuickBooks accounting. QuickBooks Desktop still requires you to do most tasks manually. In addition, QuickBooks Desktop versions have been set for discontinuation. The 2024 version is the final and is scheduled for discontinuation on May 31, 2027. This means that after May 31, 2027, users will no longer receive security updates and payroll support. This will significantly limit the software’s capabilities and force the user to switch to either the Online or Enterprise version, or to an alternative software such as Sage.

In contrast, Sage boasts deep inventory management and superior reporting capabilities. It provides businesses with robust auditing and advanced scalability. What makes it even better is the unlimited-user feature in some tiers, making Sage 50 an affordable choice for growing teams. Needless to say, businesses will switch to Sage 50 and abandon QuickBooks. Better technology always wins.

Before You Convert to Sage 50: What You Need to Know

It helps to be aware of certain things before you convert from QuickBooks to Sage. This is because the conversion is a major procedure, and a lot can go wrong, so there is a lot one needs to consider or be careful about.

  • Firstly, you need to know what converts to Sage and what doesn’t. Sage 50 will convert the lists (like employees, items, jobs, customers, vendors, accounts), transactions, and current balances in the QuickBooks file. 
  • However, what might not migrate perfectly includes attachments, audit trails, reconciliation history, custom fields, and complex inventory assemblies.
  • You would need to figure out the most suitable version of Sage 50 to switch to. This will primarily depend on the QuickBooks version you are on and your accounting requirements. Sage allows you to convert QB data that is up to three years old. 
  • Different editions, such as US Sage 50, Canadian Sage 50, UK Sage 50 Accounts, support different import tools and file formats. Thus, you need to know about the version you intend to switch to.
  • Decide on what historical data you need to migrate. For instance, would you like to transfer only opening balances, current fiscal year transactions, or full historical data to support audits and long-term reporting?

Prepare Your QuickBooks Data for Conversion to Sage 50

Sage 50 needs to be able to read your QuickBooks data properly, and thus you need to prepare the latter. For that, here is what you will need to:

Check Your QB Company Name

Check and make sure that company data includes a valid company name. To do so:

  • Navigate to the Company menu in QB, and choose Company Information.
  • You will see the Company Information window.

Moreover, your company name needs to be entered in the Legal Name field. This is because Sage 50 will read what is written in the Legal Name field and choose that as your new Sage 50 company name.

Important: However, if the Legal Name field is blank, Sage 50 will select the company name based on the data in the Company Name field. In case both of the fields are blank, the software will name your company “No Name”. Not to worry, you can change it later after the conversion.

Check the Account Types in QB Company

You need to check and make sure that there is at least one such account for the following types of accounts:

  • Account Receivable
  • Retained Earnings
  • Account Payable

Print & Process Your Checks & Bills

You must authorize all credit card transactions and process and sync all electronic bills. Moreover, process all shipments and reconcile bank accounts for the accounting periods before the conversion.

Additionally, print all checks and forms. You’ll need them.

Create a Backup of Your QuickBooks Data

You need historical company data for various security, regulatory compliance, and strategic purposes. Thus, before you convert QuickBooks files to Sage 50, create a backup of the same and store it in a secure location.

If You Want to Convert Social Security Numbers

In case you need to convert social security numbers, you need to know there is an option that will allow you to do so, and look for it when you reach the stage in the conversion wizard that needs you to have your QB company open.

You will be able to spot an Application with No Certificate window. An option that you need to mark will convert your social security numbers.

Missing Data

If Sage fails to read some data or it doesn’t align with Sage’s structure, it might not convert to Sage. This can result in incomplete records and inaccuracy.
