The problem
How many hours a week vanish into manual work?
Re-typing invoices, manual stock reconciliation, spreadsheets nobody keeps up to date, calculation errors, documents scattered across departments. The bigger you grow — the more people do the same work over and over.
× You enter the same data into three programs
× Inventory and accounting don't match
× You process e-invoices by hand, one by one
× Nobody knows the real cost per vehicle or department
One system
Every department. One source of truth.
Instead of ten separate tools — one database everyone shares. Data is entered once and flows automatically through the whole business.
Procurement
Purchase orders, goods receipts (GRN), 3-way matching of order, receipt and invoice. Requests and approvals through a workflow.
Inventory
Real-time stock, requisitions, inter-warehouse transfers, stocktaking. Always accurate — without double entry.
Fixed assets
Register, depreciation, assignment per person, write-offs. Every asset knows who holds it and what it cost.
Fleet & machinery
Vehicles, fuel, service, registrations, work orders — and the exact material cost per vehicle and machine.
HR & payroll
Employee records, contracts, leave, payroll with statutory forms. Salaries visible only to authorized users.
Cash desk & accounting
Cash operations, compensations, assignments, cessions, costings, postings and statutory ledgers — connected to everything else.
And much more
Complaints, price adjustments, travel orders, warranty certificates, reports and analytics. The system adapts to your business.

★ Built to your measure
You don't adapt to the software.
You don't adapt to the software.
We build the software around you.
This isn't a rigid, off-the-shelf program you have to squeeze your business into. CERP System is our software, which we develop and tailor exactly to your company — your processes, documents, rules and way of working. You describe how you work; we turn it into a system.
- Workflows, approvals and reports exactly the way you need them
- Your forms, code lists and specific rules — built into the system
- New features and modules on request, as your company grows
- We build the software — so there's no "that's not possible"
Automation
Software does the work people used to do.
The goal isn't "another program". The goal is for the same amount of work to be done by fewer people, faster and without errors. CERP automates what repeats — so your team focuses on what matters.
- Enter once. Data is entered in one place and flows automatically into inventory, accounting and reports.
- E-invoices without re-typing. Incoming invoices from SEF are pulled in and auto-matched to the order.
- Workflows and approvals. Requisitions, purchases and confirmations route automatically to the right person.
- Real-time control. Cost per department, vehicle and unit — instantly, without assembling spreadsheets.

FAQ
Answers before you ask.
Does CERP System support e-invoicing (SEF)?
Yes. The system is fully integrated with the Serbian e-invoicing system (SEF). You send and receive e-invoices, track statuses and automatically reconcile incoming invoices — with no manual re-typing.
How long does implementation take?
Typically a few days to a few weeks, depending on company size and number of modules. We migrate your existing data (items, prices, fixed assets, partners) and train your team.
Can we use only some modules?
Of course. Start with what you need most (e.g. e-invoicing and procurement) and add modules later. The system is modular and grows with your company.
Can you tailor the software to our specific process?
Yes — that's the whole point. We develop CERP System and build it to measure: to your workflows, forms, code lists and rules. If you need something specific, we build it in — instead of forcing you to change how you work.
Where is data stored and is it secure?
Access is over a secure connection, with precise roles and permissions — sensitive data (e.g. salaries) is visible only to authorized users. We're happy to discuss data-storage details on a call.
How much does it cost?
Pricing depends on the number of modules and users, so we prepare a personalized quote — call +381 61 567 7777 or send a request and you'll get a clear calculation.
