What makes this warehouse hard?
- Clients from different sectors with different traceability rules (lot, expiry, serial) share one building.
- Every client wants real-time visibility of its stock, orders and performance.
- Revenue depends on measuring and invoicing storage, handling and value-added services correctly.
- When a client is won or lost, master data, integrations and rules must be set up or closed down quickly.
Capabilities to look for in a WMS
| Capability | Why it matters | How to test it in a demo |
|---|---|---|
| Multi-client stock and rule separation | One client's rules do not affect another's; stock never mixes. | Have different picking rules defined for two clients. |
| Activity-based billing | Services such as pallet-days, lines, cartons and labelling are measured automatically. | Produce a sample invoice breakdown from a month of transactions. |
| Client portal and reports | Clients see their own stock and orders, reducing support load. | Log in as a client user and confirm only its own data is visible. |
| Fast client onboarding | Template-based setup and bulk master-data upload for new clients. | Watch how many steps it takes to set up a new client from scratch. |
| Value-added services (kitting, labelling) | VAS work is tracked as tasks and flows into billing. | Run a kitting job end to end. |
Ask the vendor
- Which references manage how many clients in one warehouse? In which sectors?
- Is billing standard or an add-on? How is it transferred to our accounting system?
- If a client wants to connect its own ERP, who owns the integration?
- Does the client portal require additional licences?

Frequently asked questions
What is non-negotiable for a WMS in a 3PL warehouse?
Stock and permission separation per client. One client's user must not see another's stock or pull their reports. On top of that come per-client service tariffs and period-end billing statements; without them a 3PL operation falls back to spreadsheets.
Should the client see their own stock?
Yes, and it has become a contract requirement. Ask whether there is a client portal with sub-users and role permissions; without one, every query lands on your operations team.
Can service billing come out of the WMS?
Storage, movements and value-added services need to be measured as a billing basis. Ask the vendor whether tariffs can be defined per client and whether a period-end statement is available.
