Lean ERP Manufacturing

Manufacturing software for your factory or workshop. From sales order to delivery.

Lean ERP is manufacturing software that brings your orders, bills of materials, planning, materials and shop floor together in one file. You see what needs to be made, what is still missing and where each lot went.

What should manufacturing software solve for you?

A manufacturing company rarely gets stuck on one big problem. It gets stuck on dozens of small questions. Will the material be there when the line starts? Which bill of materials applies to this order, the standard one or an adjusted one? Who is on which workstation today? And when a customer calls about a delivery: which lot of raw material went into it?

Lean ERP answers those questions from a single source. The sales order, the production orders, the purchases they need, the bookings from the shop floor and the lots in stock are all linked. Nobody retypes an order number from one system into another.

One file, from sales order to delivery

This is how an order runs through Lean. Each step builds on what the previous step already recorded.

  1. 1
    Sales orderThe order with the requested delivery date. For made-to-order work, you adjust the bill of materials in the order itself.
  2. 2
    Material requirementsThe calculation sets demand and supply per item side by side and shows where a shortage arises.
  3. 3
    Production orderA proposal from that calculation, which the planner confirms. Or a production job you create from the sales order.
  4. 4
    PlanningThe order gets a line or workstation, a start and an end. What threatens to be late shows up on the planning board.
  5. 5
    Shop floorThe operator starts, pauses, stops and books output. The components are consumed per lot.
  6. 6
    Inspection and lotWhen the order is closed, the quality questions follow. The finished product gets a lot in stock.
  7. 7
    Delivery and invoiceDelivery and invoice start from the same file.

What Lean manages for your production

Production ordersFrom proposal to closed order, with progress per order and per line.
Bills of materials and recipesMulti-level, with semi-finished products, a workstation per component and cost build-up.
Production planningPlanning board per line, Gantt per team or employee, capacity per team and per day.
Material requirementsExpected stock per item, shortages in red and purchase orders straight from the calculation.
Shop floorA screen for the operator on tablet or phone, with a scan field and output booking.
Traceability and qualityLot and shelf life per stock line, origin and destination, checks at receipt and in production.

Series production or made-to-order: both in the same system

Series production and make-to-stock. You work with production orders per line or workstation. The order carries the item's bill of materials, the components scale along when the quantity changes, and the shop floor books what is finished.

Made-to-order and one-offs. The sales order leads. You adjust the bill of materials per order and create a production job with work orders per workstation from that order. Lean proposes the hours per step from the bill of materials. You then plan the work orders per team or per employee.

Many companies do both. With Lean, you do not need a second package alongside the first.

And what information does each step need?

Production often stalls not on material but on information: an approved drawing, a measurement the customer still has to send, a check nobody filled in. IRP links each process step to the information it needs, and shows what is already there and what is still missing.

On the work orders of a job, you see per step which information elements are expected. When a production order is closed, the operator gets the inspection questions that belong to that step. Which information your steps need, we set up together at the start.

How IRP works ›

What does a product cost, and what did it really cost?

On the bill of materials, you can build up the cost price across all levels: raw materials, semi-finished products, loss per line and the work per workstation. So you know what a product costs you before you sell it.

During production, the performance overview shows per order and per line the progress, the measured pace against the standard and an expected end time. For projects, the analysis sets ordered, actual and final cost per category side by side.

What happens when things go differently?

A material shortage. If the components are not at the workplace, the shop floor cannot book output and the operator gets a message. He can record the interruption with the reason "material shortage". In the material requirements, you see which item falls short, and when.

A change to the order. If the quantity changes, the component lines of the production order scale along. For made-to-order work, you adjust the bill of materials in the order, without touching the item's standard bill of materials.

Rejected production. When closing the order, the operator records the number of rejected or rework pieces, with a reason, a comment or a photo. Those answers stay with the order.

Good to know in advance

We would rather show what Lean does today than what it might do one day. Three things work differently from what you might expect.

The planning proposes, you decide. Lean calculates start and end and shows what threatens to be late. It is not a fully self-optimising schedule across all machines.

Bills of materials have no separate versions with a validity date. A deviation for one order is recorded in that order.

Outsourced operations (for example painting or galvanising off-site) have no separate out-and-back flow. How you follow them up, we look at together at the start.

Frequently asked questions about manufacturing software

Does Lean have MRP?

Yes. The material requirements calculation sets demand per item (sales, consumption of components) against supply (stock, purchasing, production). You see the expected stock and the shortages, and create purchase orders from that calculation. Production proposals appear as provisional production orders that the planner confirms.

Does Lean work with multi-level bills of materials?

Yes. A component can itself be an item with a bill of materials. You see the full tree, and per item also in which bills of materials it is used.

Which device does the operator use?

A tablet or a phone. The shop floor screen shows the orders per workstation, with a search field that also works as a scan field for the barcode of an order or work slip.

Can I trace a lot from raw material to finished product?

Yes. Every stock line carries a lot. From one lot, you see where it came from and where it went, with a report of the trace.

Does Lean adapt to the way we produce?

Lean is configured at the start around your items, workstations, order types and checks. Because we develop the software ourselves, anything beyond that is discussed directly with the people who build it.
