Implementing a CRM, ERP, or custom internal tool in Croatia costs from €3,000 for off-the-shelf SaaS with basic setup to €150,000+ for a fully custom enterprise platform. A typical project for a small or mid-sized company - a combo of CRM, invoicing, and process automation - runs €15,000 to €60,000. The main drivers: choice between off-the-shelf (Pipedrive, Pantheon, HubSpot) and custom solutions, number of users, depth of integrations, and how much is mapped before development starts.
This article breaks down the real costs of digitalizing business processes, when off-the-shelf pays off vs custom, and how to calculate a realistic ROI.
Quick price reference by company stage
| Company stage | Approach | Cost (€) | Monthly (€) |
|---|---|---|---|
| Micro (1-10 employees) | Off-the-shelf SaaS (Pipedrive, Minimax) | 1,000 - 3,000 setup | 50 - 250 |
| Small (10-30 employees) | SaaS + custom integrations | 5,000 - 20,000 | 200 - 800 |
| Mid-sized (30-100 employees) | Custom CRM/ERP or advanced SaaS with integrations | 15,000 - 60,000 | 400 - 2,000 |
| Large (100+ employees) | Custom enterprise system or Pantheon/SAP with heavy customization | 60,000+ | 1,500+ |
CRM vs ERP - the distinction people often blur
CRM (Customer Relationship Management) tracks clients and the sales process. Who’s who, what they bought before, where they are in the funnel, when to send a follow-up. Typical tools: Pipedrive, HubSpot, Salesforce, Mautic. Users: sales, marketing, support.
ERP (Enterprise Resource Planning) tracks internal resources - inventory, orders, invoicing, payroll, accounting. Typical tools in Croatia: Pantheon, Minimax, Sage, Microsoft Dynamics, SAP. Users: accounting, operations, procurement, warehouse.
Many companies need both, because they’re different processes. Small tools cover one, larger ones (Pantheon, Microsoft) cover both.
Off-the-shelf vs custom - the decision from our other article
The rule from our earlier post:
- Off-the-shelf is the right pick if it covers 80%+ of your needs and the monthly subscription grows reasonably
- Custom is the right pick if it covers less than 70%, or your process is part of your competitive edge
For CRM/ERP specifically, an extra question: how standard are your processes? If you sell typical retail products, Pantheon or Minimax works great. If you have something specific (B2B with contracted prices, complex production process, integration with your own webshop), custom becomes rational already at 20-30 users.
What actually drives the cost
The seven biggest factors:
- Number of users. Most SaaS tools charge per user (€15-€150/month per person). For 50 users, that’s €750-€7,500/month.
- Number of integrations. Accounting, webshop, email marketing, SMS, shippers, ERP - every integration is 1-2 weeks of development.
- Existing data migration. You have 5 years of history in Excel, an old system, or somewhere else. Migration is typically 15-25% of total scope.
- User roles and permissions. If everyone has the same access, simple. If you have a complex hierarchy with different permissions (sales sees prices, support doesn’t, the owner sees everything), more complex.
- Local specifics. VAT, fiscalization, eRačun, R-1/R-2 forms - if you buy an off-the-shelf system from abroad, all of this is additional customization.
- Mobile version. Does field sales need to work from a phone? Tablet in the warehouse? Mobile apps or mobile web significantly add scope.
- Team training. The biggest hidden cost. A training plan for 30 employees can take 2-4 weeks and cost €2,000-€8,000 externally + internal time.
A typical implementation plan
What “implementing a CRM/ERP” actually means for a small/mid-sized company:
Month 1: Discovery
- Conversations with key users (sales, accounting, operations)
- Mapping current processes
- Defining what the new system must do
- Decision: off-the-shelf or custom
Month 2-3: Setup or development
- Configuring the chosen tool (if SaaS)
- Building customizations and integrations
- Preparing migration scripts
Month 3-4: Migration and testing
- Trial migration of data
- User training for the first key people
- Edge case testing
Month 4-5: Launch and stabilization
- Gradually moving work to the new system
- Training the rest of the team
- Fixing urgent bugs
- Measuring real results
Total: 4-6 months from idea to stable use. Cutting this short is the main reason digitalization projects fail.
Real ROI - what to expect
Typical results after a successful CRM/ERP implementation for a small/mid-sized company:
- Sales: 15-40% higher quote-to-order conversion (because nothing is forgotten)
- Operations: 5-15 hours per week saved per admin worker
- Finance: 30-50% shorter cash flow cycle
- Decision-making: Monthly reports that used to take a day or two now show up in real time
- Clients: Better follow-up, higher NPS, fewer clients lost to “we forgot about you”
Return on investment: typically 12-24 months, depending on company size and how chaotic things were before. Companies that worked “from their heads” pay back faster than those that already had some system, because the cost of chaos was bigger.
5 most common mistakes
-
Buying a tool before processes are mapped. Typical case: “Let’s roll out Salesforce.” Then 3 months in, you realize your process doesn’t match Salesforce’s way of working. Now you have an expensive tool that doesn’t solve the problem.
-
Trying to do everything at once. “While we’re at it, let’s get a CRM, and an ERP, and a webshop, and a mobile app.” Ends with 5 half-done implementations instead of 1 complete one.
-
Ignoring training. The best system doesn’t help if no one knows how to use it. A training plan is a mandatory part of the project.
-
No data migration plan. Old data “just transfers” - except it never does. Migration is its own project line item.
-
No plan for after launch. Who fixes bugs? Who builds new features? Without a contract with a development partner for the Operate phase, the system goes stale fast.
Frequently asked questions
Can we use Excel for everything until we buy a CRM? Yes, but it costs you. Real math: 5-10 hours/week of sales time spent on manual data management in Excel + errors + forgotten follow-ups. A small CRM (€500/month for 10 users) pays back in 1-3 months.
What if our team doesn’t want to use the new system? Resistance is expected. Three things help: (a) involving users in Discovery, (b) a concrete training plan, not just “send them a link to a video,” (c) leadership support - it must be clear the new system is mandatory, not optional.
Can we use EU funds for CRM/ERP? Yes, through NPOO and other programs. See our article on EU funds for details. Custom solutions qualify better than buying SaaS.
How do we know when it’s time to upgrade? The typical trigger: your current system is blocking growth (limited user count, doesn’t support a new process), or you’re paying more for customizing an off-the-shelf tool than you’d pay for custom.
