Challenges you may face when integrating SaaS with Salesforce
Over the years, we’ve seen a range of challenges when helping companies integrate Salesforce. Some are common, while others are more unexpected, but all can slow down operations if not appropriately addressed. Our CRO Vlad Petrovych listed a few key issues and explained how we’ve tackled them:
Data silos
Many companies come to us with the same problem—customer data is scattered across multiple tools, making it nearly impossible to get a clear, unified view of their users. Sales teams operate in one system, marketing in another, and support in yet another. As a result, businesses suffer from fragmented communication, inefficient workflows, and missed opportunities.
One of our clients, a SaaS provider using Salesforce for sales and Mailchimp for email marketing, faced this exact issue. Their teams were constantly struggling with outdated or incomplete customer data. We integrated the two platforms through an API, ensuring real-time updates. Now, when a lead interacts with a marketing campaign, that data flows directly into Salesforce, allowing the sales team to act on it immediately. With a single source of truth, they improved customer engagement and closed deals faster.
Data quality issues
Messy data is a silent killer of efficiency. Duplicates, outdated records, and inconsistencies can throw off reports and lead to bad business decisions. We’ve seen companies struggle to make sense of their numbers, only to realize that their data integrity foundation was weak.
We used Talend to clean the database before migrating an old CRM to Salesforce for one client. We removed duplicate records, corrected errors, and standardized fields to ensure consistency. By the time we imported the data into Salesforce, it was accurate, organized, and ready to drive meaningful insights. The client immediately saw the difference, as reports became more reliable and decision-making became faster and more data-driven.
Integration complexities
Connecting multiple SaaS tools to Salesforce can be challenging, especially when they use different data formats and exchange protocols. Some companies attempt manual workarounds, which often lead to inefficiencies and errors.
In one project, a client needed Salesforce to work seamlessly with Zendesk and HubSpot. Instead of building custom integrations from scratch, we used MuleSoft, an iPaaS solution that accelerated the process. Hence, the client’s customer support and sales teams can access the same up-to-date customer data, eliminating delays and reducing manual effort.
Legacy systems compatibility
Many companies still rely on legacy systems that were never designed to work with modern applications. They often lack APIs, making direct integration impossible. But replacing them overnight isn’t always an option—it’s expensive and risky.
One client had an old accounting system without an API but needed it to work with Salesforce. Instead of overhauling the entire system, we introduced an ETL process and extracted data from the accounting system, transformed it into a compatible format, and loaded it into Salesforce. With ETL the company could keep their existing system while benefiting from a centralized, up-to-date data source in Salesforce.
Different data update speeds between systems
Not all applications update data at the same speed. Some sync in real time, while others update every 15 or 30 minutes. This mismatch can lead to inconsistent data and confusion among teams relying on the latest information.
A client integrating Salesforce with a warehouse management system faced this exact issue. It updated stock data every 30 minutes, while Salesforce worked in real-time. To bridge the gap, we created an intermediate buffer that held updates until the warehouse system had fully processed them. This solution ensured that Salesforce only received accurate, finalized data, preventing discrepancies and incorrect stock levels.
Conflicts between custom system settings
Salesforce is highly customizable, but so are most SaaS applications. When two systems with different configurations need to work together, conflicts can arise—fields don’t match, workflows clash, or automations interfere with each other.
For one project, we integrated Salesforce with a marketing platform that used standard deal status fields, while Salesforce had custom fields for tracking sales stages. To prevent data mismatches, we conducted an audit of both systems and created a mapping strategy. After that, each platform recognized and correctly processed deal status updates, eliminating errors and lost data.
API quota limitations
Many SaaS platforms limit the number of API calls you can make per day or per minute. This isn’t an issue for small data exchanges, but for companies processing large volumes, hitting the limit can disrupt operations.
One of our clients faced an issue when integrating Salesforce with an analytics platform that capped API requests at 10,000 per day. Sending individual requests would have quickly exceeded the limit, so we optimized the process by batching data and sending updates once per hour instead of in real time to keep them within the API limit while maintaining data accuracy.
Mismatch in business logic between systems
Different systems define and process data differently. What counts as an “active customer” in one platform might not match the criteria in another. These inconsistencies can create reporting errors, misaligned workflows, and confusion between teams.
For one client, Salesforce marked a customer as active when a deal status was “Closed Won.” But in Zendesk, a customer was only considered active after their first support request. To bridge the gap, we created a rule that defined a customer as active if either condition was met to ensure consistency across sales and support teams.
Lack of API versioning from third-party applications
Some SaaS applications update their APIs without backward compatibility, breaking existing integrations often without warning, leaving businesses scrambling to fix data transfer issues.
A marketing platform our client used suddenly changed its API structure, causing data sync failures in Salesforce. To prevent such disruptions, we set up automated API checks using Postman and subscribed to update notifications from the SaaS provider. Now, they receive alerts about upcoming changes and can adjust their integration before problems arise.
9 steps to integrate SaaS platforms with Salesforce
A great integration is not only about syncing data. In practice, this should make your product feel like a natural extension of Salesforce. It’s about giving your users the right context at the right time in the system they already work in. We’ve seen firsthand how the difference between a basic integration and a well-designed one can impact efficiency, adoption, and even revenue.
Here’s how we approach it — step by step, based on what actually works in the real world.
Step #1: Defining clear objectives
Before you start, define why you need the integration and what problems it should solve. Is your goal to improve data accuracy, automate workflows, or provide a better user experience?
For example, suppose your sales team is spending hours manually entering order data from an ERP system into Salesforce. In that case, your goal should be to automate data transfers so that order, delivery, and purchase history updates happen in real-time. Clear objectives ensure you’re building an integration that actually improves your operations.
Step #2: Choosing the right integration approach
There are multiple ways to connect Salesforce with your SaaS platform. The right method depends on data volume, complexity, and future scalability.
- Point-to-point integration is the best for simple, direct connections between two systems;
- API-based integration is ideal when real-time, automated data exchange is needed;
- Middleware (iPaaS) works well for integrating multiple systems with minimal coding.
“Let’s say you need to connect Salesforce with a marketing automation platform to manage leads. The key is ensuring real-time data sync and seamless integration with other systems when needed. In this case, an API is the best choice. So, the right method depends on your specific needs.”
To make the choice easier, we’ve put together a comparison table outlining the pros and cons of each approach:
Step #3: Searching for a reliable integration partner
Salesforce integrations can be complex, and building an in-house team for this project isn’t always practical. A specialized Salesforce partner brings experience, best practices, and ongoing support to the table reducing risks and accelerating the process.
A good Salesforce integration partner should have:
- Deep technical expertise in Salesforce architecture and APIs: not just one-time developers, but platform specialists.
- Experience working with SaaS products and similar industries, so they understand your product model, data structure, and customer journey.
- Workflow-first thinking. They not just sync fields, but design end-to-end flows that improve UX and team efficiency.
- A track record of successful delivery: proven projects, measurable outcomes, and ongoing support beyond launch.
Instead of trial and error, a trusted partner ensures your integration is efficient, scalable, and future-proof.
Step #4: Mapping and transforming data
Before integrating your SaaS platform with Salesforce, you need to map and transform data to ensure consistency and accuracy. This step involves identifying where your data is stored, how it’s structured, and how it needs to be formatted for Salesforce.
- Determine which systems hold the data you need to migrate: legacy CRMs, email marketing tools, customer databases, or financial software. For example, if you’re migrating customer data, you need to pull records from your existing CRM, marketing platform, and support system to ensure a complete view of customer interactions.
- Review how data fields are structured. Your old CRM might have fields like "First Name," "Last Name," "Email," and "Phone Number," while Salesforce organizes customer information under objects like "Contact" or "Lead." Understanding these differences is crucial for preventing data mismatches.
- Develop a mapping document outlining how each field in the source system corresponds to Salesforce fields. Some data may require transformations. For instance, if your current system stores a full address in a single field (e.g., "123 Main St, Springfield"), Salesforce may require it to be split into Street Address, City, and State fields.
- Use solutions to automate this process. ETL tools like Talend or Informatica help extract, clean, and load data efficiently. You can set up an ETL job to pull customer data from your old CRM, apply transformation rules, and load it into Salesforce while maintaining data integrity.
- Run a test migration with a small sample to verify that fields are correctly mapped and transformations are applied properly before migrating all data. Review the results to catch errors, discrepancies, or missing information. Once the test migration is successful, proceed with the full data transfer according to your mapping plan.
Step #5: Developing a comprehensive testing plan
A successful Salesforce integration requires thorough testing before full deployment. Without it, data errors, workflow disruptions, and system conflicts can arise, leading to costly setbacks.
Start with small-scale testing by syncing a limited dataset between your SaaS platform and Salesforce. This helps identify potential issues with data synchronization, formatting, and automation rules.
Once the data flows correctly, move on to user testing. Employees from sales, marketing, and support teams should test how the integration affects their workflows. For example, sales reps can check whether lead assignments work correctly, while customer support can verify that customer interactions are properly logged in Salesforce.
Only after passing these tests should you fully launch the integration. A phased rollout works best, starting with one department or region before expanding company-wide. This approach minimizes disruptions and allows teams to adjust processes gradually.
Step #6: Ensuring data security
Data security is critical when integrating your SaaS platform with Salesforce. Without proper protection, sensitive customer and business data could be exposed to unauthorized access or breaches.
To protect data during transfer and storage, use encryption methods that prevent unauthorized access. Salesforce offers Shield Platform Encryption, which encrypts data at rest, while TLS encryption secures data in transit. Additionally, access controls should be configured so that only authorized users can view or modify confidential information.
Security also extends to user authentication. Implement two-factor authentication (2FA) for all Salesforce users and enforce strong password policies to minimize the risk of account breaches. For secure data exchange between systems, API communications should use OAuth 2.0 or JWT authentication to prevent unauthorized connections.
By securing your integration at every level, you reduce the risk of data leaks and ensure compliance with security standards like GDPR, HIPAA, and SOC 2.
Step #7: Providing user training and support
Even the most well-built integration is only as effective as the people using it. A successful rollout depends on proper user training so that employees can leverage Salesforce efficiently.
Start by developing user guides that outline key functions and workflows. Conduct training sessions where employees can practice real scenarios, such as managing leads, tracking customer interactions, and generating reports.
To provide ongoing support, set up a knowledge base with answers to frequently asked questions. Organize webinars and Q&A sessions to address common challenges. Additionally, provide access to a dedicated support service so users can quickly resolve issues as they arise.
A well-trained team ensures that the integration delivers its intended value, improving adoption rates and overall efficiency.
Step #8: Monitoring and optimizing performance
Once your Salesforce integration is live, constant monitoring is necessary to ensure smooth performance and efficiency. Issues such as slow data synchronization, API errors, or workflow bottlenecks can negatively impact operations.
Key performance indicators to track include:
- Data synchronization speed across integrated systems;
- Frequency of failed API calls, missing records, or incorrect data mapping;
- Amount of processing power that is required for integration tasks.
To track performance, use monitoring tools such as:
- Salesforce Health Check to evaluate security settings and integration health;
- New Relic or Datadog to monitor API response times and system performance;
- Postman to test API connections and identify failures;
- MuleSoft Anypoint Monitoring to get insights into data flow efficiency for iPaaS integrations.
If performance issues arise, adjustments can be made by optimizing API calls, modifying batch processing, or refining data transformation rules to improve speed and accuracy.
Step #9: Planning for scalability
Your business will grow, and your Salesforce integration should be built to grow with it. A short-term solution may work today, but if it is not designed for scalability, it will require costly modifications later.
To future-proof your integration, choose scalable tools and technologies. Instead of relying on point-to-point connections that become hard to manage, consider using middleware solutions like MuleSoft or Workato that allow for flexible expansion.
Additionally, design your data architecture so it can handle increasing volumes:
- Optimize API calls to manage high-traffic loads efficiently;
- Use asynchronous processing where real-time updates aren’t necessary;
- Configure Salesforce data storage policies to manage large datasets effectively.

FAQs
How do I build a custom Salesforce integration?
Building a custom Salesforce integration starts with defining the objectives and identifying the data that needs to be shared between systems. The next step is choosing an integration method—this could be a point-to-point connection, API-based integration, or middleware (iPaaS) solution like MuleSoft or Workato. If using APIs, Salesforce provides REST and SOAP APIs for retrieving and updating data. Developers typically use Apex, Java, or Python to write integration logic, handling authentication via OAuth 2.0. Before deployment, rigorous testing in a Salesforce Sandbox ensures smooth data exchange and security compliance.
How do I use the Salesforce Metadata API for integrations?
The Salesforce Metadata API is primarily used for managing customizations and automating deployment processes. It allows developers to retrieve, deploy, update, or delete metadata components such as custom objects, fields, workflows, and layouts. To use it, developers first authenticate via OAuth or a connected app, then send requests in XML format via SOAP API. Tools like Salesforce DX (SFDX) and Workbench simplify Salesforce SaaS management. A common use case is deploying changes across multiple Salesforce environments without manual reconfiguration, ensuring consistency and reducing errors.
How do I handle large data volumes during Salesforce integrations?
Integrating large data sets with Salesforce requires careful planning to avoid API limits, performance slowdowns, and data integrity issues. Using Bulk API 2.0 instead of REST API allows batch processing of large records efficiently. Data deduplication and validation rules should be applied before migration to maintain accuracy. ETL tools like Talend and Informatica help extract, clean, and load large datasets while maintaining structure. Additionally, asynchronous processing and indexed queries with selective filters prevent system overloads, ensuring smooth and scalable data handling.
