Fulfilment & 3PL

WMS for 3PL: multiple customers, one environment, no chaos.

Tremo is multi-tenant from the ground up. Every fulfilment customer has their own environment inside your WMS: own stock, own carrier rules, own packing slips, own portal. No white-label licence, no separate instances.

What keeps 3PL owners up at night

You have 4 customers, 6 carriers, 2 warehouses and one spreadsheet that has to make sense of it all. Four patterns we see again and again:

Every customer has their own demands a spreadsheet can't hold

Per fulfilment customer: own carrier rules, own packing slip template, own cutoff time, own billing rates, own portal branding. All in the same Tremo.

Customers call for every 'how much is left?'

Customer portal per customer. They see their own stock, orders, return status and advice — without ever seeing your other customers. Calls turn into self-service.

Manual carrier choice per shipment is error-prone

Carrier rules out of the box: by weight, country, customer or cutoff. Defaults inherit per fulfilment customer. One click on 'ship' picks the right carrier automatically.

Invoicing customers is still manual labour

Per-customer tariffs (pick, pack, shipping, storage) are tracked automatically. Audit-log per action so you can bill transparently — even during disputes.

What 3PLs find here

A WMS that doesn't fall apart when the third customer joins. Real multi-tenant — not one tenant with a tab for customers.

Strictly separated per customer
Customer A can never see customer B's data — not in the UI, not through an API. The separation lives in the database itself, not in the UI. Full audit export on request.
Customer portal per customer
Own URL, own branding (logo, colour theme), own users. Customers see orders, stock and advice — nothing else.
Carrier rules per customer
DHL for customer A, PostNL for customer B, MyParcel as fallback. Auto-pick by weight, country, customer or cutoff. Defaults inheritable.
Per-customer packing slip templates
Own logo, own footer, own sender on the slip. No designer needed, everything editable in the UI.
Per-customer carrier credentials
Every customer has their own PostNL or DHL account? No problem. Tremo ships with the right credentials per shipment. More carriers (DPD, GLS) run via MyParcel; direct integrations are added step by step.
Audit-log per action
Who picked what, when it was booked, which return was accepted. Searchable in the UI, exportable for disputes or compliance.

Frequently asked questions

What 3PL operators and fulfilment managers want to know before switching.

How many fulfilment customers can I host?+

Portals per fulfilment customer and the billing engine belong to Enterprise / 3PL (custom quote). Only shipping your own stock? Then you're on Free, Growth or Core.

Does each customer get their own environment or just a tab?+

Every fulfilment customer has their own environment inside your Tremo. To them it feels like their own WMS; to your pack-floor it's an aggregated view of all customers. Customer A can never see customer B's data — that separation lives in the database itself, not just in the UI.

Can I put my own branding on customers' portals?+

On Fulfilment and Enterprise: yes. Your own logo and brand colour in the customer portal. No extra licence fee, no partner call. A custom subdomain is on the roadmap.

How does invoicing customers work?+

Per-customer tariffs (pick-fee, pack-fee, shipping, storage per pallet) are counted automatically. At month-end you export to your accounting tool or our webhook fires off automatic invoice creation.

Can a customer get a fully isolated, dedicated environment?+

On Enterprise / 3PL, that's possible: a dedicated, isolated Tremo environment for that customer. Mostly relevant for data-residency requirements.

Can I automate onboarding of new customers?+

Yes. Our WordPress plugin provides a signup form that lands new customers straight in your Tremo, with logged acceptance of terms. For other websites there's a REST API.

One WMS, all customers.
