WMS vs ERP for Warehouse Operations
Let’s break down the key differences of ERP vs WMS systems in terms of their core capabilities.
WMS core features
and scope
A WMS provides
advanced features for the following warehouse needs:
Inventory: Conducts replenishment, receipt and
putaway according to pre-defined rules, with the ability to automatically
allocate stock via strategies like FIFO (first in first out).
Fulfilment: Suggests optimal picking routes, generates pick
lists, facilitates barcode scanning and use of picking strategies, and
facilitates quality control.
Location
management: Optimises
space utilisation and warehouse layout, and automatically allocates stock to
optimal storage locations.
Reporting: Real-time dashboards allow you to track
warehouse KPIs, orders, inventory and shipments.
ERP core features
and scope
There’s a small amount
of overlap between WMS and ERP systems, but the latter offers a far broader
range of capabilities. These include:
Accounting: General ledger, tax and cash flow management
Finance: A real-time view of financial performance and
features for managing billing, budgeting, consolidations and financial close
Fulfilment: Visibility of stock levels and features to
manage storage, replenishment, and customer orders
Global business: Management of global operations in
multiple currencies and according to regional tax requirements
HR: Payroll, time tracking, rosters and staff
leave processing
Risk
management: Transaction
controls, business continuity planning and audit management
Sales and
marketing: Management of
leads, sales and customer interactions.
WMS: Strengths and
limitations
The key strength of a
WMS is that it focuses purely on warehouse operations and therefore offers more
advanced capabilities to enhance efficiency. This specialisation allows it to
manage tasks at a level of operational depth that broader systems generally do
not cover.
Where a WMS falls
short, however, is in its scope. Because it’s purely focused on warehouse
operations, it requires integration with other platforms (e.g. an ERP or
accounting software) to get a full picture of the business. This is a natural
trade-off of its specialised design rather than a weakness of any specific
solution.
ERP: Strengths and
limitations
An ERP is especially
valuable to businesses as it provides all the tools they need for key financial
and operational functions. It integrates multiple applications and data in one
platform, providing a single source of truth for the entire business, not just
individual teams.
But because an ERP is
an all-in-one platform, its functionality (most notably its WMS features) is
often limited. Another big downside is that the implementation process is far
more complex and costly.
