Inventory & Order Software for 3PLs and Fulfilment Providers

WhiteBox gives third-party logistics (3PL) and fulfilment providers a single system to manage inventory and orders across every client — real-time stock, barcode picking and packing, multi-warehouse control, and a unified order queue. Run a tighter, more transparent operation that wins clients and keeps them.

The 3PL’s hardest problem: accuracy at scale

When you fulfil for other brands, their stock is your responsibility — and every miscount, every oversell, every late dispatch lands on you. Multiply that across dozens of clients, hundreds of SKUs and several warehouses, and the margin for error vanishes. WhiteBox is the control layer that keeps it all straight: one accurate, real-time source of truth for every client’s inventory, wherever it sits.

What you get

Multi-client, multi-warehouse inventory — accurate stock by client, location and SKU, in real time.
Barcode pick, pack and ship — fast, verified fulfilment with carrier labels and tracking.
A unified order queue — every client’s orders from every channel, in one place.
Channel integrations on your clients’ behalf — Shopee, Lazada, TikTok Shop, Shopify and Amazon, synced.
Client-ready reporting — service levels and stock reports you can hand straight to the brands you serve.

Turn operations into a selling point

Brands don’t just buy storage and shipping — they buy peace of mind. When you can show a client a live, accurate view of their stock and prove your dispatch times, you’re no longer a commodity 3PL competing on price. Visibility becomes your differentiator, and the reporting WhiteBox generates does the talking for you.

Scale without the chaos

Onboarding a new client shouldn’t mean another spreadsheet and another set of logins. With WhiteBox, each new brand plugs into the same system — their SKUs, their channels, their stock — so you grow your client book without growing your headcount or your error rate. The operation that handles ten clients handles a hundred the same way.
