ERP system
What is an ERP system?
An ERP system is one piece of software in which a company runs its stock, sales, purchasing, finance and production on a single database. Each department works in its own module but reads the same item codes and the same quantities. When the warehouse books a delivery in, sales and accounting see the change without entering it again. An ERP system is a project, not an install.
Example
A parts distributor keeps 4,000 items in one warehouse and sells over the counter, through an online shop and through two field reps. Stock lives in three places: the inventory program, the accounting program and the website. Every morning somebody exports a report and uploads it to the shop, and by the afternoon the sales have already moved past it.
With an ERP system there is one item list. A delivery is booked once, and the same quantity is what the rep, the till and the site show. At 40 orders a day and three minutes of copying per order, about two hours of work a day disappear; at an internal cost of €10 an hour that is close to €400 a month spent on orders instead of retyping. The amounts are illustrative — the gain that counts is the smaller gap between what was promised and what is on the shelf.
Why it matters for a business
An ERP system is a decision about data, not about screens. It gives one place where an item has one code, one unit and one quantity, plus a record of who changed what. Every other system — the site, the till, the CRM, the accounts — then reads and writes through a described interface instead of keeping its own version of the truth.
A rollout runs in stages: describing the processes, moving item lists and balances, training, and a spell of running the old system alongside the new one. The expensive part is rarely the licence; it is the state of the data and the change in what people do each morning. Where the system will record sales in a Bulgarian shop, what the software has to meet under the tax rules is a point to settle with the accountant before any code is written.
Connecting an ERP system to an online shop is the work we do as warehouse sync: quantities and prices go out to the site on a schedule, and orders come back into the system.
What to ask
- Which processes go in first, and which ones wait for a second stage?
- Which system wins when two of them report a different quantity for the same item?
- How does the data get out — is there a described interface, or only reports to download?
- What happens to the history: are old documents moved across, or kept in an archive only?
- Who maintains the connections afterwards, and whose job is it when a supplier changes a format?
