Enterprise resource planning (ERP)
ITLine builds custom ERP for trading and manufacturing SMEs. Orders, proforma invoices, invoicing, stock and a reseller portal on one database. Every phase ends with a live part.
The order arrives by e-mail. Someone copies it into a spreadsheet, then into the invoicing tool, then into the stock sheet.
At fifty orders a day this still works. At a hundred and fifty it takes two people, and the same data is re-keyed six times. That is where the errors come from, not from carelessness.
One system from order to invoice: order intake, proforma invoices, invoicing, stock and a reseller portal, on one database.
The system reads orders that arrive by e-mail and matches them to the product master. What it is unsure of, it puts up for review instead of guessing.
It is built in phases with a fixed scope. Every phase ends with a part that runs live, and each phase's price is known in advance.
The system adds the item number to every line it reads from the email. Where two items could fit, it does not choose for you: it flags the line, and a colleague decides.
Manual entry does not disappear; it turns into checking.
The back office lived in three places: e-mail, a spreadsheet and the invoicing software. Today it is one system, holding order intake, proforma invoices, invoicing, stock and the reseller portal, with a webshop alongside. The team uses it in daily work.
Most orders arrive as free-text e-mail. Extraction is automatic and uncertain line items go for review. Manual entry did not disappear: it turned into review, and that is the difference.
A building-materials wholesaler’s complete business system, live since 14 June 2026. Our own measurement from the project’s delivery record; product-master size as of August 2026. One project’s measurement, not an average.
How often the system errs in production, and what it does about it: What if the system is wrong in production?
In phases: at the end of the first one, order intake or invoicing already runs live. We state the full timeline after the assessment, phase by phase. The measured pace of one delivered system is under Measured above.
The quote follows the assessment, for a fixed scope and priced by phase, so each phase's price is known in advance: What it costs.
No. What works stays: the invoicing software, the webshop and accounting receive data from the new system. If an off-the-shelf product is enough, we say so.
If the company is a few people and the trouble is a scattered calendar, notebook and invoicing tool, you get order without an ERP: Back-office software for small firms. With orders, stock and resellers, ERP is the right route.
The system works on your own database. Where it runs, who processes the data and the GDPR data processing agreement are set in the contract. If some data must not leave the company, say so at the assessment.
The full write-up, with cases and the measured error rate: Enterprise management and trade. How the work runs: How we work.
We do not replace a working system because it is old. If your accounting software is good, it stays: we build next to it. And if it turns out a boxed product will serve you, we say so.
