Instead of another generic article on digitalization, today we go into concrete stories. We will show three typical profiles of Slovak companies we work with and walk through, step by step, how digitalization with Modulario changed their day-to-day work. The stories are illustrative, drawn from a composite of real implementations where we deliberately combined data from multiple projects to protect sensitive client information. The numbers, however, are real and averaged from the portfolio of our case studies.
If you find yourself in one of the profiles, the same mechanism is likely to work for you too.
Story 1, An electronics e-shop (18 employees)
Starting point
A medium-sized e-shop offering consumer electronics. Annual revenue of 3.8 million EUR, 18 employees (6 in warehouse operations, 4 sales, 3 customer care, 2 accountants, 3 IT/management). The company has existed for 9 years, growing from a garage startup to a stable regional player.
Problems before digitalization:
- Orders from 4 channels (own e-shop, Heureka, eBay, B2B portal) manually retyped into the warehouse system
- Invoicing manual, the salesperson spent 2.5 hours a day creating invoices
- Stock levels updated once a day at night, 20-30 mismatches between sales channels per week
- Complaints tracked in Excel, records lost after 6-8 months
- Payroll administration manual, attendance in a paper book
Business goals:
- Shorten the time from order to shipment from 48 hours to 12 hours
- Eliminate selling out-of-stock goods
- Get a single view of the customer across channels
Selected solution
Implementation of Modulario modules: E-shop connector (for connecting WooCommerce + Heureka + eBay), Warehouse, CRM, Invoicing, Complaints, Attendance. The project took 3 months including data migration.
Concrete results after 9 months
- Time from order to shipment: from 48 hours to 9 hours (improvement of 81%)
- Manual order retyping: 0 minutes per day (previously 4 hours a day = 960 hours saved per year)
- Salesperson’s time on invoicing: 25 minutes per day (previously 2.5 hours = 546 hours saved per year)
- Duplicate sales out of stock: dropped from 22 cases per month to 1-2 cases
- Customer NPS: from 42 to 68 (one of the most visible changes)
- Accountant’s time on monthly close: from 7 days to 2.5 days
Financial impact in the first year:
- Wage and time savings: about 38,000 EUR
- Additional revenue thanks to faster shipping and better NPS: about 180,000 EUR
- Reduced loss from errors: about 14,000 EUR
- Total positive impact: 232,000 EUR
- Investment (license + implementation + training): 29,000 EUR
- ROI: 700% in the first year
Tip: For e-shops, sales channel integration is the single largest source of savings. Before choosing a solution, map all channels (including B2B email orders) and make sure the vendor has ready-made connectors, custom development costs 5-10x more.
Story 2, A manufacturing company (43 employees)
Starting point
A family-owned manufacturer of plastic components for automotive. 43 employees (28 in production, 4 technology, 3 quality, 4 administration, 4 management). Annual revenue of 5.6 million EUR, 95% exports to Germany, Austria, and Czechia.
Problems before digitalization:
- Production orders on paper, getting lost on the shop floor
- Production planning in Excel, with every change in a job they had to redo the whole plan (2-3 times a week)
- Tracking operations at every production step, manually, slowly, inaccurately
- Quality recorded on paper, defect analysis was a quarterly process instead of operational
- Customers calling twice a week with “Where is my order?”, the salesperson had to physically walk to production and find out
- Attendance and payroll separated from performance, no feedback on productivity
Business goals:
- Speed up the response to a customer change request from 72 hours to 8 hours
- Reduce the rate of defective parts from 3.2% to 1%
- Provide the customer with real-time order status
Selected solution
Modulario modules: Production (MRP II), Raw material + finished goods warehouse, CRM, Invoicing, Attendance, Quality. Additionally, QR codes were deployed at every workstation for operation reporting, with a tablet in every production cell. Implementation took 5 months.
Concrete results after 12 months
- Response to change request: from 72 hours to 6 hours (improvement of 92%)
- Defective parts rate: from 3.2% to 1.1% (improvement of 66%)
- Planner time on rescheduling after a change: from 4 hours to 25 minutes
- OEE (Overall Equipment Effectiveness): from 58% to 74%
- Real-time order status: available in the customer portal, the number of phone inquiries dropped by 78%
- Time from order receipt to confirmed deadline: from 2 days to 20 minutes (automatic planning)
Financial impact in the first year:
- Reduced losses from defective parts: about 68,000 EUR
- Increased capacity thanks to better OEE: about 320,000 EUR (even with a conservative count of just 40% of capacity)
- Administrative savings (planning, customer communication): about 42,000 EUR
- Total positive impact: 430,000 EUR
- Investment: 78,000 EUR (including production hardware)
- ROI: 451% in the first year
Tip: Manufacturing companies often underestimate the value of “real-time visibility” for the customer. In a B2B contract with German automotive, where the customer has a portal showing the status of their orders, the probability of repeat contracts grows significantly and the supplier’s negotiating power increases.
Story 3, A services company, IT consulting (23 employees)
Starting point
A mid-sized IT consulting firm specializing in DevOps implementations and cloud migrations. 23 employees (18 consultants, 2 sales, 2 administration, 1 finance). Annual revenue of 2.1 million EUR, 70% of revenue from time & materials contracts.
Problems before digitalization:
- Timesheets in Excel, every consultant with their own methodology
- Invoicing manual, on average 12 days after month-end
- Project profitability calculated once a quarter, too late to intervene
- Sales pipeline in Pipedrive, but with no link to consultant capacity, frequently selling a project they had no one to deliver
- Vacations and overtime in another Excel, HR checking manually
- Reporting to clients, manual, 3-4 hours per month per client
Business goals:
- Shorten the cash-to-cash cycle from 47 days to 30 days
- Increase consultant billable rate from 68% to 78% of time (the rest is internal)
- Automate client reporting
Selected solution
Modulario modules: CRM (connected to Pipedrive), Project management, Timesheet, Invoicing, Attendance, Vacations, BI Dashboard. Implementation took 2.5 months (less complex than the manufacturer).
Concrete results after 10 months
- Cash-to-cash cycle: from 47 days to 31 days (improvement of 34%)
- Consultant billable ratio: from 68% to 76% (target almost reached)
- Time to invoice: from 12 days to 3 days after month-end
- Client reporting: automated, available in the client portal in real time
- Project profitability: daily visibility for every project, interventions on slips in time
- Capacity overload: reduced by 60% thanks to visibility of consultant availability in sales
Financial impact in the first year:
- Increased billing (8% additional billable hours): about 180,000 EUR
- Administrative savings (invoicing, reporting): about 28,000 EUR
- Better cash flow (17 days shorter cycle): freed up about 95,000 EUR of working capital
- Total positive impact: 303,000 EUR
- Investment: 22,000 EUR
- ROI: 1,277% in the first year
What these stories have in common
At first glance these are three very different companies, an e-shop, a manufacturer, services. But they share elements that determined success.
Element 1, Clearly defined business goals
None of the companies bought an ERP “because it would be good.” Each had 2-3 concrete goals with a numerical metric. After a year it was easy to evaluate whether they were achieved.
Element 2, Phased implementation
Nobody deployed all modules at once. They started with 2-4 key modules that addressed primary goals. Additional modules came only after the first ones stabilized.
Element 3, Integration with existing tools
No company threw out everything old. The e-shop stayed in WooCommerce but linked to Modulario. The IT firm did not lose Pipedrive but tied it to internal project management. Pragmatism over the purist “everything in one.”
Element 4, Investment in people
All three companies allocated 15-20% of the budget to change management, communication, training, sandbox, post-go-live support. They knew well that a system without people does not work.
Element 5, Choose a vendor with industry experience
The e-shop chose an implementer who had already done 15 similar integrations. The manufacturer chose a partner with a manufacturing background. The IT firm, a partner that is itself an IT firm. Empathy and know-how have immense value.
Tip: If you are planning an ERP project, compare your plan against these five elements. Missing one? Add it before signing the contract. Missing three? Start over from the goals phase, without them the project has no chance.
Which modules most often deliver immediate value
Across all three stories (and dozens more in our portfolio), four modules repeatedly emerge as delivering quick returns:
- Invoicing with automatic creation, on average saves 5-15 hours per week
- Warehouse with real-time availability, eliminates duplicate sales and stock variances
- CRM connected to sales channels, single view of the customer, end of lost leads
- Attendance linked to payroll, saves 2-4 hours a week on the HR side
These four modules cover 60-80% of the quick value for a typical SMB. The rest (production, project management, BI, quality) adds value, but takes longer to implement and is less visible in the first year.
Average across the portfolio, what to expect
When we average 40+ projects in our portfolio, we get the following realistic expectations:
- Time savings on administration: 30-50% (average 38%)
- Reduction in process errors: 40-70% (average 55%)
- Cash-to-cash cycle reduction: 15-35% (average 24%)
- Increase in user satisfaction (measured by NPS): +10 to +30 points
- ROI in the first year: 150-1,500% (average 470%)
- Time to ROI: 4-18 months (average 9 months)
The numbers are sharper at smaller companies (2-20 people), where every automation has a larger relative impact. At larger companies (100+) the percentage gains are lower, but the absolute numbers are orders of magnitude higher.
Conclusion, digitalization is not a luxury, it is hygiene
Three stories, three different industries, three different sizes. One common conclusion: digitalization with a modular ERP brings a Slovak SMB 30-50% savings in administrative time, significant reduction in error rates, and ROI over 100% in the first year. These are numbers that five years ago meant a competitive advantage. In 2026 they are basic business hygiene, a company without them gradually loses position to competitors.
