ERP (Microsoft Dynamics 365 Business Central) and CRM (Microsoft Dynamics 365 Sales) – do you really need both?
If you already have an ERP system – like Dynamics 365 Business Central – you might be wondering whether you also need a CRM. It’s a fair question. Every investment should make sense, and since both systems seem to revolve around customer data, it’s easy to think that one might be enough.
But while ERP and CRM have things in common, their roles are entirely different. ERP, like Business Central, includes some sales-related functions – like quotes – but this is hard data: product lists, pricing, terms. CRM, on the other hand, is a different world. It’s all about relationships, prospects, sales opportunities, and the conversations in between. Trying to manage the entire sales process through ERP alone? That gets tricky fast.
Picture a typical day at the office: Invoices are sent, inventory levels match up, and orders are flowing. But then…
- Sales is trying to pick up an old thread but has to dig through their inbox to find the context – the client brief, the RFP, or notes from earlier conversations. ERP has the quote, but none of the backstory that led to it.
- Marketing launches a campaign in the dark, relying on ERP’s hard data – company name, tax ID, client status. But it lacks soft info: who showed interest in what, who joined the last webinar, who clicked which email.
- A salesperson is trying to remember what they promised a client – whether they sent the catalog, discussed terms, which option the client was leaning toward, or if they got manager approval for extra discounts.
ERP does its job – it manages processes and numbers. But it won’t tell you who spoke with the client, what was said, what the client has already seen, or what they’re interested in. That’s where CRM steps in.
ERP - the quiet hero of operations
Dynamics 365 Business Central is like the company engine – your accountant and logistics coordinator in one. It handles everything happening internally:
- Finance
- Production
- Inventory
- Supply Chain
Finance and ops teams rely on ERP to keep everything aligned – from order to delivery.
Below, you can see an order screen in Business Central, showing which products are available and which are reserved. This makes it easier to manage inventory and avoid errors.
The dispatch board in Business Central gives you a quick view of open service orders, who’s handling them, and their current status. This is a classic ERP use case: keeping operations running smoothly behind the scenes.
You can also see key sales data in Business Central: funnel stages, open opportunities, customer interactions. ERP helps track this in the context of fulfillment and service – but it doesn’t give the full picture of the relationship, conversation history, or future sales forecasts. For that, you need CRM.
CRM – so you don’t miss a sales opportunity
Dynamics 365 Sales (CRM) focuses entirely on the customer:
- Tracks communication history
- Helps acquire new customers and re-engage dormant ones
- Manages relationships and sales processes
- Supports forecasting and pipeline management
Sales and customer service teams are the primary users of CRM. It supports the full sales journey – from first contact to deal closure.
Imagine a client calls asking about a quote from six months ago. Without a CRM, finding it is a time sink. With CRM, it’s right there.
Below is a sample screen from Dynamics 365 Sales. You can see the full history of interaction with the customer – from website visits to emails and calls. Everything is in one place.
Sales Accelerator in Dynamics 365 (see image below) walks salespeople step by step through the process. It shows what needs to be done now – send a reminder, follow up, prepare a quote – and what’s coming next. This is especially helpful for teams managing longer cycles or many leads at once.
In the short video below, you can see how Copilot in Dynamics 365 helps quickly draft a customer message – no tab-hopping or copying from Excel.
Copilot also helps sales reps analyze conversations, suggest next steps, and forecast outcomes. This gives the team not only a snapshot of what’s happening now, but also what’s likely to happen next.
How do ERP and CRM work together?
- CRM handles relationships. ERP handles fulfillment. Together, they manage the full process and help you deliver on what you promised.
- They share the same data – no duplication, no mess.
- With CRM, you can quickly generate quotes using ERP data pulled straight into the system.
In the screen below, you see the same order reflected in both systems: on the left, ERP (Business Central); on the right, CRM. They use the same data, but each presents it in a way that suits the user – finance vs. Sales.
Below is a CRM screen showing a full view of customer activity – meetings, emails, calls, notes – all in one place, in chronological order. Thanks to this, sales always knows the context and doesn’t have to search through inboxes or spreadsheets. This view makes it easier to plan next steps and respond quickly.
In the product reservation example, ERP shows inventory status, and CRM gives sales real-time access to that info.
Who needs what?
CRM is ideal for sales and customer service teams:
- Strengthen customer relationships
- Track and manage the sales process
- Understand customer behavior and needs faster
ERP is a better fit for operations and finance teams:
- Manage finances and inventory
- Gain control over data
- Ensure processes run smoothly
Two systems, one customer view
Integrating CRM and ERP isn’t just about clean data. It saves time and leads to better customer service. Some studies show that companies integrating both systems reduce their customer response time by up to 35%.
Each system does something different, but together they offer the full picture: ERP shows what’s happening inside the business (e.g. when a product ships), while CRM shows what’s happening in the customer relationship (e.g. “Hey, can we revisit my request from three months ago?”).
With both systems connected, teams don’t work in the dark – they have the data, history, agreements, and customer needs all in one place. They respond faster, plan better, and use tools like Copilot to even analyze tone and suggest replies.
That’s when ERP and CRM show their true value: working together. The client feels heard, sales knows the deal status, and production knows what to deliver and when.
If you’re thinking it might be time to level up your setup, see what a connected CRM and ERP can change. You might be surprised how quickly you see results.
