Lean ERP connects your business operations with the information and the people involved. So less has to pass through you.

Does this sound familiar?

Work nobody sees. Time everybody loses.

“Didn't I already enter that?”

Record it once. Keep working together.

Information gets one fixed place in the file. Your team works on the next steps with the same data, without entering it again.

“I still need to let that colleague know.”

Changes reach the people who need them.

Configured notifications keep the people involved up to date. You have less to remember and pass on yourself.

“The customer is calling again: where are we?”

Customers and partners see their part too.

Through their portal, customers and partners follow what is relevant to them, with access based on their role.

ERP + IRP for your industry

Every industry has its own questions. Lean answers them in one file.

How we make that possible

A complete ERP. Your process as the starting point.

We translate the way you work into steps, required information and responsibilities in the software. So less depends on memory and on what someone passes on personally.

  1. Quote
  2. Confirm
  3. Prepare
  4. Execute
  5. Invoice
The business software

Lean ERP manages your work.

From quote and order to purchasing, stock, production, planning and invoicing, in one solution.

The information layer in Lean ERP

IRP connects every step with what it needs.

For each process step you define which information is needed, who provides it and which steps depend on each other. The people involved see what is relevant to them.

We call this approach Information Requirements Planning: IRP.

We want to reduce the time lost to searching, duplicate work and passing things on. That is why we build and support it ourselves.

Questions when choosing an ERP

What you want to know before you switch.

Is Lean a good fit for us?

Lean supports production, property development, windows and doors, catering and food, among others. We always start from your own process, and in a demo we look together at whether it fits.

See the industries →

How does the switch work?

We discuss your processes and set up Lean with your documents and data. Your people learn to work with their own files, and our own people guide the start-up.

How we get started →

What do we keep?

Your accounting stays in your accounting package: Lean passes the invoices on to it. There are integrations with Exact, Yuki, Octopus, WooCommerce and Shopify, among others, and an open API for other packages.
