ACT CRM Sage 50 Integration Guide [2026 Updated]

If you use ACT! CRM for managing customer relationships and Sage 50 for your accounting, you know the frustration of having critical data stuck in two separate systems. Manually entering new customer information from ACT! into Sage 50 is slow, invites errors, and creates a disconnect between your sales and finance teams. This guide provides an updated, step-by-step walkthrough for integrating these two powerful tools, helping you create a unified workflow that saves time and keeps your data consistent across the board.

Why Connect ACT! CRM and Sage 50?

Connecting your customer relationship management (CRM) software with your accounting system bridges the gap between sales activities and financial realities. When a sales team member can see a client’s payment history directly within ACT!, they can have more informed conversations. When your finance team automatically receives accurate invoice data from a closed deal, billing becomes faster and more reliable. The goal is to create a single source of truth for all customer and financial information.

Here are the primary benefits you can expect:

• Eliminate Manual Data Entry: Stop wasting time copy-pasting customer details, sales orders, and invoice information. An integration automates the transfer, freeing up your team for more valuable work.
• Reduce Human Error: Manual entry inevitably leads to mistakes like typos in names, incorrect addresses, or wrong invoice amounts. Automation ensures the data in Sage 50 perfectly matches the data from ACT!.
• Improve Cash Flow: By automatically generating a sales invoice in Sage 50 the moment a deal is marked "won" in ACT!, you can bill clients faster and shorten your payment cycles.
• Provide 360-Degree Customer Views: Give your sales team visibility into a customer's payment status, credit limits, and purchase history. This context is invaluable for upselling, collections, and relationship management.
• Streamline Workflows: Create a smooth handoff from your sales process to your financial process. The connection acts as a digital bridge between departments, making sure everyone is working from the same real-time information.

Understanding Your Integration Options (Since There's No Native Connector)

As of 2026, ACT! CRM and Sage 50 do not offer a direct, built-in integration. This means you can't simply flip a switch inside either application to make them communicate. Instead, you'll need to use an intermediary tool or a custom solution to build the connection. Your options generally fall into two categories.

1. Third-Party Integration Platforms

This is the most popular and accessible method for most businesses. Platforms often called "iPaaS" (Integration Platform as a Service) act as a middleware bridge that connects thousands of different applications without requiring you to write any code. You create automated workflows by setting up a "trigger" in one app that causes an "action" in another.

Popular choices for this task include:

• Zapier: Known for its user-friendly interface and vast library of app connectors. It's an excellent choice for straightforward workflows and is what we'll use for our step-by-step example.
• Make (formerly Integromat): Offers more visual and complex automation scenarios, making it suitable for users who need to build multi-step workflows with conditional logic.
• Workato: An enterprise-grade platform designed for more robust, high-volume, and company-wide automation processes.

2. Custom API Integration

An API (Application Programming Interface) is a set of rules that allows different software applications to communicate with each other. Both ACT! and Sage 50 have APIs that developers can use to build a completely custom, direct integration tailored to your company’s exact needs. This route offers maximum flexibility but also requires technical expertise, development resources, and ongoing maintenance. It's best suited for businesses with unique workflow requirements that off-the-shelf integration platforms cannot meet.

Step-by-Step Guide: Integrating ACT! CRM and Sage 50 with Zapier

For most businesses, using Zapier is the fastest and most efficient way to connect ACT! and Sage 50. In this example, we’ll build a common workflow: when a new contact is created in ACT!, a corresponding customer record is automatically created in Sage 50. The same principles apply to other workflows, like creating invoices from "won" deals.

Step 1: Get Your Accounts Ready (Prerequisites)

Before you begin, make sure you have everything you need:

• An active ACT! CRM account with administrator permissions that allow you to manage integrations.
• An active Sage 50 account (cloud-connected version) with administrator access. API access must be enabled.
• A Zapier account. While you can start with a free plan to build the workflow, automating multi-step syncs often requires a paid plan.

Locate your API credentials or be prepared to log in to both your ACT! and Sage 50 accounts directly through Zapier’s authentication prompts.

Step 2: Create a "Zap" and Set the Trigger in ACT!

Login to your Zapier dashboard and click the "Create Zap" button.

1. Choose the Trigger App: In the search box, type "ACT!" and select it.
2. Select the Trigger Event: Zapier will ask you to choose what event in ACT! should start the automation. Common options include "New Contact," "New Opportunity," or "Opportunity Stage Changed." For this guide, select "New Contact." Click "Continue."
3. Connect Your ACT! Account: Zapier will prompt you to sign in to your ACT! account. Follow the on-screen instructions to authorize the connection. Once linked, click "Continue."
4. Test the Trigger: Zapier will attempt to pull in sample data from your ACT! account (e.g., your most recently added contact). This confirms the connection is working and gives you data to use for mapping in the next steps. Choose a sample and click "Continue."

Step 3: Define the Action in Sage 50

Now that the trigger is set, you need to tell Zapier what to do in Sage 50.

1. Choose the Action App: In the second step of your Zap, search for "Sage 50" and select it.
2. Select the Action Event: You'll see a list of actions Zapier can perform in Sage 50. Common choices include "Create Sales Invoice," "Create Customer," or "Update Customer." Since our trigger is a new contact in ACT!, the logical action is "Create Customer." Select it and click "Continue."
3. Connect Your Sage 50 Account: Similar to before, follow the prompts to sign in and authorize Zapier to access your Sage 50 account.

Step 4: Map Your Data Fields

This is the most important step. You are telling Zapier how to match information from ACT! with the correct fields in Sage 50. The "Create Customer" action in Sage 50 will show a list of fields (Name, Email, Phone, Address, etc.).

1. Click inside the "Name" field for Sage 50. A dropdown will appear, showing you the data pulled from the ACT! "New Contact" trigger in the previous step.
2. Select the appropriate field from ACT!. For example, you’d select the "Name" field from ACT! to map to the "Name" field in Sage 50.
3. Repeat this for all relevant fields: map ACT! Email to Sage 50 Email, ACT! Phone to Sage 50 Phone Number, and map the address fields accordingly.
4. Be meticulous. An incorrect mapping here will result in jumbled data. Once finished, click "Continue."

Step 5: Test, Activate, and Monitor Your Zap

Before turning your integration on, run a final test.

1. Zapier will show you a summary of the data it's about to send to Sage 50 based on your mapping.
2. Click "Test step." Zapier will send the test contact's information to your Sage 50 account.
3. Log in to your Sage 50 account and confirm that the new customer was created correctly. If it looks good, you're ready to proceed.
4. Finally, click "Publish Zap" to turn your automation on. Now, every time a new contact is added in ACT!, a customer record will be created in Sage 50 within minutes.

It's good practice to monitor your Zap history in Zapier for the first few days to ensure everything is running smoothly.

Advanced Workflows and Common Pitfalls

Once you are comfortable with the basics, you can create more powerful workflows. For instance, you could set up a Zap where a "Deal Won" in ACT! automatically creates a detailed "Sales Invoice" in Sage 50, mapping over the customer, products, quantities, and prices. This alone can save hours of administrative work each week.

Watch out for these common issues:

• Data Mismatches: If a field is required in Sage 50 but not in ACT!, the Zap will fail. Make sure your data collection in ACT! includes all the information you need for Sage 50 records.
• Custom Fields: Syncing custom fields can be tricky. You may need to use their specific API names in the mapping, which can sometimes require digging into the settings of each app.
• Authentication Errors: If you change a password in ACT! or Sage 50, your Zap will stop working. You’ll need to reconnect the application within your Zapier account.

Final Thoughts

Connecting ACT! CRM and Sage 50 is an investment in efficiency. By using a platform like Zapier, you can build a bridge between your sales and accounting teams, ensuring data flows automatically, accurately, and in real time. This D-I-Y approach gives you control over your workflow without needing a developer.
