in one piece.

A plain-English answer

What is Standard ERP?

One system for the work that keeps a business moving: accounts, orders, stock, invoicing and customers. Built by HansaWorld, used around the world, and flexible enough that we can shape it around how you already work.

What’s slowing you down?

Most of the businesses we work with didn’t come to us asking for an ERP. They came with a problem. Pick the one that sounds most like your week.

Real screens, built on Standard ERP

A few of the tools we’ve built on top of Standard ERP. Each one started with someone saying “I just want to see it all in one place.”

Customer dashboardSales, margin, invoices, quotes and activity for one customer, on one screen. Item dashboardStock, orders, purchase orders and price lists for any item at a glance. Bank statement matchingBank lines paired with payments automatically. Confirm the match and move on. File viewerAttached invoices and documents read right inside the record. No downloading.

Customer dashboard in Standard ERP: a customer list on the left, and for the selected customer a sales and gross profit chart by month with this year against last year, plus sales analysis figures.

Item dashboard in Standard ERP: an item list on the left, and for the selected item its details, stock in hand, on order and on purchase order, recipe items and price lists.

Bank statement matching in Standard ERP: imported bank lines on the left, and for the selected line two suggested payment matches with confidence scores and buttons to create a payment or transaction.

File viewer in Standard ERP: a list of attachments on the left and a purchase invoice PDF displayed inside the record on the right.

To confirm: these four screens are ITSI-built tools (their window titles say “Sample”) and can be described as our work
