ERP or CRM: What Does Your Business Need First?
By CodexierPublished 5 min read
Growing companies often reach the point where spreadsheets and email no longer hold the business together, and the question becomes which system to buy first. Vendors blur the answer: CRMs add invoicing, ERPs add customer modules. The clearest way to separate them is by process. A CRM covers everything before and around the sale; an ERP, in Swedish often called an affärssystem, covers everything after it. This guide explains both, where they overlap, and a simple way to decide which one your business needs now.
What a CRM covers
A CRM is the system of record for relationships and sales: who your contacts and companies are, which conversations are happening, what stage each deal is in, and what needs to happen next. It is used daily by sales, customer success and often marketing. HubSpot, Pipedrive, Salesforce and Lime are common choices in Sweden.
- Contacts, companies and their history of calls, emails and meetings.
- Deals and pipeline stages, with forecasts.
- Tasks and reminders for follow-up.
- Quotes and, in some systems, e-signing.
- Marketing lists, forms and email, depending on the product.
What an ERP covers
An ERP runs the operational and financial side: what was sold, what must be delivered, what it cost, and what must be invoiced and booked. For a small Swedish company the accounting system is often the ERP core, extended with order, stock, project or time modules. Larger companies move to systems such as Business Central, Visma's larger products or industry-specific platforms.
- Orders, delivery and stock, including purchasing from suppliers.
- Invoicing, accounts receivable and payable, and VAT reporting.
- Bookkeeping, month-end and annual accounts.
- Projects, time reporting and cost follow-up in service businesses.
- Article and price registers.
Where they overlap
| Area | CRM | ERP | Usual master |
|---|---|---|---|
| Customer name and contact person | Yes | Yes | CRM for contacts, ERP for billing details |
| Organisation number and invoice address | Often | Yes | ERP |
| Quotes | Yes | Often | CRM until signed |
| Orders | Sometimes | Yes | ERP |
| Products and prices | A copy | Yes | ERP |
| Invoices and payment status | A view | Yes | ERP, shown in CRM |
Decide one master system per field. Two systems that both think they own the customer's address will disagree within weeks.
Which pain is bigger for you
Look at where time and money leak today. If sales people keep their pipeline in their heads, leads go unanswered and nobody knows what will close this quarter, the problem is before the sale and a CRM comes first. If deals close fine but orders get lost, stock is wrong, invoices go out late or month-end takes a week, the problem is after the sale and the ERP side comes first. Our overview of CRM systems for Swedish small businesses helps if the answer is CRM.
CRM first
Consultancies, agencies, B2B services and anyone with a sales cycle longer than a few days and more than one person selling.
ERP first
Webshops, wholesalers, manufacturers and trades with orders, stock or many invoices, where operational errors cost more than lost leads.
Neither yet
A company with a handful of customers and one person selling may be best served by a well-structured accounting system and a shared inbox.
Connecting them later
- Choose systems with open APIs, so an integration is possible without changing vendor.
- Use the same customer identifier, such as the organisation number, in both.
- Agree which system owns each field before you start entering data.
- Start with one flow: a won deal creates a customer and order in the ERP, and invoice status flows back to the CRM.
- Document the integration so the next supplier or employee can maintain it.
Our comparison of Fortnox and Visma integrations covers the Swedish accounting side. When you do not need an audit: if you already know which system to buy and your processes are simple, pick it and start. An audit helps when you have both systems half in use, data in several places and no clear owner. Our CRM setup audit maps your process and gives a recommendation; see pricing or book a call.
Frequently asked questions
Can one system do both CRM and ERP?
Some can, and for a small company an all-in-one can be simpler. The trade-off is that the CRM part of an ERP is often weaker for sales teams, and the ERP part of a CRM rarely handles Swedish accounting well. Most small companies end up with two systems and an integration.
Is Fortnox an ERP?
Fortnox is primarily an accounting system with modules for invoicing, orders, stock and time that together form a small-company ERP. For many small Swedish businesses it covers the ERP side without anything else.
What does it cost to connect a CRM and an ERP?
It depends on the systems and how many flows you need. Ready-made connectors can cover simple cases; custom integrations make sense when you need control over fields, errors and history. Start with one flow and expand.
Should sales people have access to the ERP?
Usually not directly. Show what they need, such as invoice status and order history, inside the CRM through an integration. That keeps the ERP clean and sales in one tool.
Not sure which system to fix first?
