GUMU™ Sage 100 CRM

Connecting Sage 100 with Sage CRM provides customer-facing staff with the option to view accounting data and create orders through the Sage CRM interface.  This is a fully bi-directional solution where users can have access to Sage 100 data wherever and whenever they log into Sage CRM. 

The information we are providing on this page refers to the GUMU™ which is the Greytrix version of the Sage 100 to CRM integration.

  • Sage CRM users do not require a license for Sage 100
  • Sage 100 does not need to be the latest version
  • Of all the GUMU™ integrations out there (Sage 100 to SFDC, Sage 100 to MS-CRM, etc.), the integration between Sage 100 and Sage CRM is the best/deepest.

YTD / LYTD Sales Summary

This is my favorite screen as it allows CRM users to readily see unit sales this year versus last year by both units and sales value. 

Users can also filter the data by units.

Creating Orders

Users can view orders, but more importantly they can create orders in Sage CRM. In configuring the integration, inventory and pricing managed in Sage 100 synchronizes with Sage CRM’s inventory.  This allows us to leverage use Sage CRM’s Quotes and Order modules, so that users (anywhere) can generated Quotes and Orders that, on approval, can be promoted into Sage 100’s Sales Order Module.   

Users can create a Quote or Order from the context on an Opportunity, or directly from the Company Summary screen

Sage 100 CRM Create Order

Items can be added to the Quote/Order either one-at-a-time or quickly using the Quick Line Entry feature.


The Quick Line Entry screen does not currently support inventory items from Sage 100 with the type Charge, Comment or Lot/Serial. Currently, if a user wants to add one of those items, they must enter those types of products via the New Line Item button feature/screen.

If a user has the correct rights, they can promote a Sage CRM Order to the Sage 100 Sales Order module.  When this happens, the Sage 100 Order Reference writes back to Sage CRM.

*NOTE – these Sage CRM Orders can also be promoted directly do a Sage 100 invoice if required.

Linking a Sage 100 RMA to a Sage CRM Case

Sage CRM is great for managing customer service issues and all of the communications related to the issue.  In Sage CRM we refer to these as ‘Cases’ and you can link a Sage 100 RMA to a case.

This video shows you how to link the RMA and there is a more detailed video which starts with this inbound email on this page.

Vendor Integration

In the set up of your system, we can import any existing vendor companies from Sage 100.  

New vendor companies created in Sage CRM can be promoted into Sage 100 (if the user has the correct permisions)

Here is an example of a Vendor Summary screen in Sage CRM.  

Sage 100 CRM Vendor Companies

Inventory Lookup

Just like how we Find Companies or People, this integration allows user to look up Inventory from the Sage CRM Finder menus

Sage 100 CRM Find Inventory

From the inventory finder screen, you can drill into an item and see Order History as well as a list of customers who have purchased the item.

Item Sales History Detail


The integration component provides an administration section within Sage CRM.  It is from here that we configure the integration and import customers, vendors, inventory (products) and map Sage CRM users to Sage 100 Sales Rep codes.


On top of all the general security principals within Sage CRM, the Sage 100 module has it’s own security screen used to define the rights you want individual users to have.

Common Modifications

This integration can be modified to meet the unique requirements of your organizations.  More often than not, companies elect to make changes to the integration, some minor and some more significant.  Below you will find a short list of common modifications.

Including key Sage 100 statistics to the Outlook interface
Adding User Defined Field from Sage 100

Yes, absolutely we can modify your integration to include an user defined fields you may have created in Sage 100.

1 to Many: Mapping a Single CRM Company to Multiple Customer Records

By default, integrations between CRM and 100 allow for only a single relationship.  Example: 1 CRM company pointed to 1 Customer record.  However, some organizations have multiple accounting databases with the same companies appearing in more than one database.  For these situations, we use an extension to the integration that allows for a single company record in CRM to be connected to multiple accounting databases (Customers or Vendors).  We refer to this requirement as 1 to Many. 

From the Linked Companies tab, we can establish the connection between the single Sage CRM company and multiple Sage 100 records, as well as define the default relationship. 

Sage 100 CRM 1 to Many

When we move through the integrated screens, the user has the option to filter records by Linked Companies

Sage 100 CRM 1 to Many
Using Serialized Inventory at the Order Level

If your organization needs to assign a serial number to an item at the Quote level (as opposed to the invoice level), we can now accommodate this requirement. Even on the Quick Line Entry screens.

If your company uses Serialized Inventory and applies the serial number at the Quote level, you may require an add-on component to make this work.  Please contact me for details – Dan 

Comparing the 2 versions of the Sage CRM to Sage 100 integration

Please note, that there exist 2 very different options for setting up the integration, the first option is published by Sage and the second option (aka GUMU™) is published by a development partner called Greytrix.

Here at My CRM Manager, we strongly endorse the version of the integration published by Greytrix.  It is far more robust, faster, more flexible, and easier to support.  The information we are providing on this page refers to the Greytrix version of the Sage 100 to CRM integration. 

This 2-minute video starts with the Sage (free) version of the integration and then covers the Greytrix version (above) at a very high level.

In the Sage version of the integration, you are essentially just launching Sage 100 screens from CRM.  This has significant limitations for many companies that do not want users in Sage 100.  Other significant limitations of the Sage version include:

  • The Sage version requires Sage 100 to be installed on the user’s workstation
  • The Sage version only works inside the LAN
  • The Sage version only works with a single Sage 100 database
  • The Sage version only works with very specific versions of Sage 100
  • The Sage version has a very limited feature set

About the Publisher - Greytrix

The Sage 100 to Sage CRM integration is published by Greytrix. Greytrix has been a Sage CRM development partner for over 20 years and has an excellent reputation within the global Sage Community. 

Aside from this integration with Sage 100, Greytrix also publishes the default integration between Sage CRM and Sage 500, Sage X3, and Sage Intacct.  Beyond Sage CRM, Greytrix also publishes the leading integration between Sage 100 and

Greytrix Logo Dark


What is the cost for this integration? The integration is sold as an annual subscription rate of $192/user/year.

What does GUMU mean? GUMU stands for ‘Greytrix Universal Migration Utility’.  This name is associated with the framework used in all of their integrations between CRM and accounting. 

How is Sage 100 licensing impacted?  CRM users do not need direct login access to Sage 100. However, the integration does require a single dedicated Sage 100 user license for CRM to talk to Sage 100.  This Sage 100 license is used while writing from Sage CRM to 100 (insert/update) and also while adding line items.  For example, at the time of any promote process (promote customer, or promote order), the integration logs into Sage 100 using the available license –> writes to Sage 100 –> logs off of Sage 100. So that means if it takes 2-3 seconds to promote a customer from Sage CRM to Sage 100, then the license is consumed for those 2-3 seconds and a license will need to be available.  In larger installs of Sage CRM with a high volume of integration activity, our recommendation is to have 2-3 Sage 100 licensing available.

What versions of Sage 100 are supported?  The integration does support older versions of Sage 100.  Clients do not need to be current with Sage 100.

How is this integration supported?  Greytrix will work in tandem with your local Sage partner (if not My CRM Manager) to assist in setting the system up.  Level 2 support by Greytrix is included in the subscription rate.

What are the system requirements? Here is a link to download our Pre-installation checklist for the GUMU™ Sage 100 CRM integration. Additionally, here are the system requirements for Sage CRM and the general pre-installation checklist for Sage CRM.

How can we evaluate this system in detail? Demonstrations of this solution are available on request and for a more thorough evaluation, we offer a fixed fee Pilot Package.

Can our instance of Sage CRM be hosted in the Cloud?  Yes, this integration can be set up anywhere an connect to your on-premise Sage 100 instance. The conditions that must be met for this to be feasible include:

  • IIS should be installed on the Sage 100 server.
  • Sdata should be installed on the Sage 100 server.
  • Sdata URL should be accessible through the internet and should also be accessible from the Sage CRM server.
