From a costed BOM to
the finished part,
fully planned

A released order explodes its multi-level BOM, MRP turns demand into a production, component and raw-material plan, and work orders run the process route sheet operation by operation. Good quantity moves WIP → finished goods, rejection and rework are captured, and engineering change is controlled through ECN — all on one manufacturing ERP for businesses of every kind, cloud or on-premise.

How it works

From engineering BOM to
finished goods — in five moves

Production and planning sit at the centre of Fast ERP. A released order from Sales & CRM drives the BOM; shortages flow into Purchase; every movement posts through Inventory & Stores.

Build the BOM/BOR
Author a multi-level, structural BOM with its bill of resources — child materials, machines, labour and operations
Explode & plan (MRP)
MRP nets demand against stock into production, component and raw-material plans — make or buy
Release work orders
Schedule against machine loading, reserve and issue material, and release WO/SWO to the floor
Run the route
Operators complete each operation on the process sheet, booking good and reject quantity as WIP
Transfer to FG
Good quantity posts WIP → finished goods; rejection and rework are captured for salvage and analysis
01 — Multi-Level BOM & Bill of Resources

The whole product tree,
down to raw material

A finished product is rarely one level deep. Fast ERP holds the full structural BOM — sub-assemblies nested inside the parent, each carrying its own child materials and a bill of resources (BOR): the machines, labour and operations a level consumes. Explode one finished-goods order and it rolls all the way down to raw material. Build the structure once as a master, or build a BOM against a specific order acceptance so a make-to-order job carries its own tree without touching the standard.

Bill of resources (BOR) — machines, labour and operations per level
BOM-against-OA for make-to-order jobs, separate from the master
BOM costing rolls child material and resource cost up to the finished product

02 — Engineering Change Control (ECN)

Change the design,
without losing control

Drawings change, materials get substituted, a process gets revised. Fast ERP raises an engineering change notice (ECN) against the affected item or BOM, documents what changed and why, routes it for approval, and releases it with a controlled effective point — so production and procurement pick up the new revision, not the old one. A change dashboard tracks what is pending, approved and released, and the controlled-document subsystem keeps the superseded drawing on record for traceability and audit.

03 — Process Routes, Work Orders & WIP → FG

The floor runs the route,
the ERP tracks every piece

A process route sheet is the ordered sequence of operations a part passes through — each on a work center, to a standard time, against a process specification. Work orders (WO / SWO) run to it: operators complete each operation and book good and reject quantity as work-in-progress. When the route finishes, a WIP-to-finished-goods transfer posts good quantity into stock. Line rejection and the rework loop catch what does not pass, so nothing is lost between the shop floor and the stores ledger.

04 — MRP, Machine Loading & the Plan

Turn demand into
a realistic plan

MRP is where planning earns its keep. From the sales plan and released orders, Fast ERP explodes BOMs into a production plan, a component plan and a raw-material plan, nets them against stock on hand and reorder levels, and proposes what to make and what to buy. Shortages flow into the procure-to-pay cycle as purchase requisitions; the production plan schedules work orders. A Gantt machine-loading view — driven by each operation's work center and standard time — shows where capacity is tight, so you level the load and commit dates you can actually hit.

Everything production and planning covers

Multi-Level & Structural BOM

A full product tree with sub-assemblies nested to any depth, a master or built against an order, exploding down to raw material.

Bill of Resources & Costing

Machines, labour and operations per BOM level, with BOM costing and the process-cost report rolling cost up to the finished product.

Engineering Change (ECN)

Controlled change management — ECN raised, approved and released with an effective point, tracked on a change dashboard.

Process & Route Sheets

Ordered operations by work center and standard time, with process specifications and an in-process inspection branch.

Work Orders → WIP → FG

WO/SWO run to the route, good and reject booked as WIP, then transferred to finished goods with rejection and rework captured.

MRP & Machine Loading

Production, component and raw-material plans netted against stock, scheduled on a Gantt machine-loading view.

"The BOM, the plan and the work order used to live in three different places. Now one released order explodes the structure, MRP nets it against stock, and the work order runs the route — and the reject is booked where it happened."

Common questions

Production, planning & BOM FAQs

What is a multi-level (structural) BOM in Fast ERP Software?

A multi-level or structural BOM is a bill of materials that nests sub-assemblies inside the parent — a finished product built from semi-finished items, each with its own child materials and a bill of resources (machines, labour, operations). Fast ERP holds the whole tree, so exploding one finished-goods order rolls all the way down to raw material. It also builds a BOM against a specific order acceptance, so a make-to-order job can carry its own structure without changing the master. BOM costing then rolls material and resource cost back up to a costed product.

How does engineering change control (ECN) work?

When a drawing, material or process changes, Fast ERP raises an engineering change notice (ECN) against the affected item or BOM. The change is documented, routed for approval and released with a controlled effective point, so production and procurement pick up the new revision instead of the old one. A change dashboard tracks what is pending, approved and released, and the controlled-document subsystem keeps the superseded drawing on record — which also feeds Quality & APQP for automotive PPAP and control-plan traceability.

How do work orders move from WIP to finished goods?

A released order explodes its BOM, reserves and issues material, and drives work orders on the shop floor. Operators run each operation on the process route sheet and book good and reject quantity as work-in-progress. When the route completes, a WIP-to-finished-goods transfer posts the good quantity into stock; reject and scrap are captured for the line-rejection and rework loop. Every movement posts through the shared Inventory & Stores ledger, so inventory valuation stays live.

What does MRP produce in Fast ERP Software?

MRP turns demand into action. From the sales plan and released orders it explodes BOMs into a production plan, a component plan and a raw-material plan, nets them against stock on hand and reorder levels, and proposes what to make and what to buy. Shortages flow into the procure-to-pay cycle as purchase requisitions, while the production plan schedules work orders — visible as a Gantt machine-loading view so you can see how each work center is loaded.

Does Fast ERP show BOM costing and machine loading?

Yes. BOM costing rolls the cost of every child material and resource up the structure to a costed finished product, and the process-cost report rolls operation cost up per work order. Machine loading is shown as a Gantt view driven by each operation's work center and standard time, so planners can level the load and commit realistic dates. Reject and cost data can also flow into Dhruv AI for clustering and trend analysis.
