Guide to choosing and implementing an ERP in your company
Implementing an ERP is a decision that affects every area of the company. This guide explains when it makes sense to take the step, what to compare when choosing, what implementation looks like and how to tell whether it is working.
When should you move from Excel to an ERP?
Excel works while the company is small and few people touch the same data. The signs that it is no longer enough are well known: stock does not match between the system, the warehouse and sales; invoices, collections and payments are tracked in separate spreadsheets; and production costs are only known at month-end close.
An ERP brings those areas together in a single information base. When a sale is recorded, it shows up in inventory and invoicing; when a purchase is received, stock is updated. The result is less time reconciling spreadsheets and more real-time information for decision-making.
What should you compare when choosing a business ERP?
Rather than the number of features, compare how well it covers your critical processes. Check whether it handles several warehouses and transfers, issues electronic invoices according to your country's rules, controls purchasing from the request for quotation to goods receipt, and records manufacturing costs during production.
How it grows also matters: a modular ERP lets you start with what is urgent and add modules later. Ask what happens when a process has its own rules; in our case, we solve it with custom software. And decide where it will be hosted: as a web-based system, it can run on a cloud architecture without your own servers.
What does implementation look like, and what data should you prepare?
It starts with an assessment: we learn how each area works, what documents it issues and where the problems are today. With that, we define which modules go live first and how they are configured.
Then come migration and go-live. It pays to prepare the master data in advance: product catalog, customers, suppliers, warehouses and opening balances. Reviewing them before loading avoids carrying duplicates and errors into the new system. Training is done by area, because each user needs to master their part of the process, and after go-live we provide support to answer questions and make any adjustments needed.
What mistakes should you avoid, and how do you measure results?
The most common mistake is trying to implement everything at once. Another is keeping parallel spreadsheets “just in case”: as long as they exist, the team does not trust the system and data gets duplicated. It also helps to appoint someone in each area to validate the information.
To measure results, compare before and after on concrete indicators: differences between system stock and physical counts, time needed to close the month, outstanding invoices, and production costs known on time. If those indicators improve and decisions are made with data from the system, the ERP is doing its job.
