“We already have an ERP. Why do we need Salesforce?” We hear this question constantly from manufacturers. The short answer: they solve different problems. Trying to use one for both jobs always ends badly.
What ERP Does Well
Enterprise Resource Planning (ERP) systems are the operational backbone of manufacturing. They manage:
- Inventory management – tracking raw materials, WIP, and finished goods
- Production planning – scheduling work orders and managing shop floor operations
- Purchasing – procurement, vendor management, and receiving
- Financial accounting – general ledger, accounts payable/receivable
- Order fulfillment – shipping, invoicing, and delivery
ERP is about what you make and how you make it. It's transactional, operational, and internally focused.
What CRM Does Well
Customer Relationship Management (CRM) systems focus on everything before and after the transaction:
- Lead management – tracking prospects and moving them through the funnel
- Opportunity tracking – managing deals, forecasting revenue
- Customer service – case management, support ticketing, customer satisfaction
- Marketing automation – campaigns, email marketing, lead nurturing
- Account management – understanding customer history, preferences, and potential
CRM is about who you sell to and how you sell to them. It's relationship-focused and externally oriented.
Why Using ERP as CRM Fails
Many manufacturers try to stretch their ERP to handle sales and customer management. Here's what happens:
- Sales reps hate the interface and stop using it
- Pipeline visibility disappears into spreadsheets
- Customer history is limited to transactions, not relationships
- Marketing has no way to track campaign effectiveness
- Service teams can't see the full customer picture
Why Using CRM as ERP Fails
Similarly, trying to run manufacturing operations in Salesforce alone doesn't work:
- No native inventory management or warehouse operations
- Can't handle complex BOMs or production scheduling
- Missing procurement and purchasing workflows
- No shop floor execution capabilities
- Financial accounting requires a separate system anyway
The Best of Both Worlds
The solution isn't choosing between ERP and CRM—it's integrating them. When Salesforce and your ERP work together, you get:
- Sales can check real-time inventory and delivery dates
- Orders flow automatically from quote to production
- Customer service sees order status without logging into ERP
- Complete customer visibility across all interactions
- Each system does what it does best
This is exactly why Rootstock exists—it's an ERP built natively on Salesforce, eliminating integration complexity while giving you best-in-class capabilities for both CRM and manufacturing operations.
