If you’re using Unleashed Software for inventory management, you’ve probably found its strengths: real-time stock tracking, barcode scanning and multi-warehouse support. You’ve probably found its limits too. Unleashed is built as an inventory management system (IMS), not a warehouse management system (WMS). Its Warehouse Management app adds bin locations and mobile scanning for picking, packing and receiving, but it doesn’t offer wave picking, pick route optimisation or automated 3PL billing.
This article walks through the best Unleashed Software alternatives for UK warehousing and 3PL operations, including Clarus WMS, which is built for the operational complexity Unleashed wasn’t designed for.

What is Unleashed Software and why look for an alternative?
Unleashed is a cloud-based inventory management system for small to mid-sized businesses, and it’s now part of The Access Group. It tracks stock levels, manages purchase orders, handles stock across multiple warehouses and integrates with sales channels like Shopify and Amazon. For basic inventory visibility (knowing what you have, where it is and when to reorder), Unleashed works well.
But Unleashed is fundamentally an inventory management system, not a système de gestion d'entrepôt. The difference matters in practice:
- Inventory management systems (IMS): Track what you have and the total quantity in each location. Unleashed tells you “we have 500 units of product X in Warehouse A” and syncs with sales channels so you don’t oversell.
- Warehouse management systems (WMS): Direct how goods move through the warehouse: receiving, putaway, replenishment, picking, packing and despatch. A WMS tells you “the next 50 units of product X are in bin C-15-4, and today’s pick route visits that bin in this order.”
For businesses managing their own stock, such as ecommerce shops, small distributors and basic wholesale, Unleashed’s inventory management is often enough. For 3PLs, multi-client warehouses and complex picking, the gaps start to hurt. Here’s where you’ll struggle on Unleashed:
- No 3PL client billing: Unleashed is built for businesses selling their own stock, not for invoicing clients for storage, handling or labour. A 3PL running on it ends up counting picks, storage and value-added services by hand at month-end.
- No wave picking or route optimisation: Unleashed’s warehouse app supports picking with scanning, but it doesn’t batch orders into waves or plan pick routes. In a warehouse with hundreds of SKUs across many locations, that means more walking and more time per order.
- No 3PL client portal: Unleashed has a B2B ecommerce portal for your own trade customers to place orders, but there’s nothing for 3PL clients to check their own stock, order status and charges. Those questions come to your team by phone and email instead.
- Limited carrier and TMS connections: Unleashed connects to the major sales channels and to shipping tools like Starshipit, but it isn’t built around carrier selection, pallet networks or transport management, which 3PLs rely on.
Clarus WMS: built for 3PL and multi-client operations
Clarus is an agentic AI-driven, cloud-based WMS for UK 3PLs, multi-client warehouses and distribution operations. The idea is simple: replace spreadsheets and manual processes with a system that grows with your business, without enterprise complexity.
What makes Clarus different
Séparation des titres entre plusieurs clients : Clarus keeps each client’s inventory, workflows and reporting separate within a single warehouse. Client A’s stock is barcode-tracked separately from client B’s, and every client view is tenant-isolated, so nobody sees anybody else’s data. This is foundational for 3PL operations, and it’s something Unleashed isn’t built to do.
Moteur de facturation automatisé : Clarus 3PL billing records billable work at source and prices it automatically: putaway, picks, packs, storage days, cycle counts and value-added services, plus ad-hoc sundry charges. Live revenue builds up for every job, so completed tasks turn into invoice lines without anyone counting them up. Finance still reviews invoices before they’re exported to your accounting software. Garde-meubles de St John's Hall, a UK 3PL, cut its invoicing time from four hours per run to under 20 minutes after switching to Clarus, a 90% reduction.
Sélection intelligente des vagues : Clarus batches orders into waves and optimises walking paths, cutting travel time by 50% compared with working from manual pick lists. Vérification de la numérisation en temps réel checks every item against the order before the packer can carry on. If the barcode doesn’t match, the system stops and flags it, which is how Clarus enforces 99.9% accuracy.
Portail en libre-service pour les clients : Through the Clarus client portal, clients see their own live stock, orders, charges and KPIs, and get alerts when orders are released, picked or despatched. The portal carries your branding, and you control what each client user can see. That means fewer “where’s my stock?” calls landing on your team.
Automations and triggers: Set rules that fire automatically when something happens in the warehouse. For example, continuous replenishment keeps pick faces topped up without someone having to spot the gap first.
Cloud-based and well connected: Clarus runs in the cloud, so there are no servers on site to maintain. It connects to over 200 systems through its intégrations, including Shopify et Amazon Shipping, carriers such as DHL, UPS, La Poste Royale, DPD, Evri et TNT, pallet networks including Palletways et Pall-Ex, ERPs and accounting packages, and TMS platforms like Qargo.
Dans quels cas Clarus n'est-il pas la solution adaptée ?
If you’re a very small business managing your own stock in a simple warehouse with low order volumes, Unleashed or a basic inventory system may be all you need, and it’ll likely cost less. Clarus is also cloud-only, so if you need on-premise infrastructure for security or compliance reasons, it won’t be the right fit.
Clarus pricing and implementation
Clarus pricing is tiered. Core covers single-site warehouses with the full picking suite, unlimited couriers and standard reporting. Scale adds multi-warehouse control, advanced picking, 3PL client portals and AI insights, and is aimed at 3PLs and multi-site distributors. Enterprise adds global site sync, a staging environment and 24/7 dedicated support. Orders, shipments, SKUs, locations and carriers are unlimited on every tier.
Implementation is a one-off fee covering configuration, SKU cleaning and custom courier logic. A Clarus specialist confirms the exact figures for your setup, and the Clarus onboarding page explains how go-live works.

Who it’s best for: 3PLs running complex, multi-sector operations, and businesses that need their WMS to work closely with an ERP.
Unleashed Software: strengths and limitations
What Unleashed does well
- Visibilité en temps réel sur les stocks : Unleashed is good at showing what you have, where it is and how much is available across multiple warehouses.
- Intégration du commerce électronique : Connections to sales channels such as Shopify and Amazon mean orders flow into Unleashed without manual entry.
- Multi-location support: You can manage stock across multiple warehouse locations in one system.
- Barcode scanning: The Warehouse Management app scans barcodes and QR codes at SKU level for picking, receiving, putaway and stock checks, with serial number tracking for traceability.
- Cloud-based: No servers to manage, and an accessible starting point for small businesses.
- B2B ecommerce portal: Unleashed includes a B2B ordering portal so your trade customers can place orders and check stock availability.
Where Unleashed falls short
- No full warehouse management: Unleashed is an inventory system first. It doesn’t batch orders into waves, optimise pick routes or plan replenishment the way a dedicated WMS does.
- No 3PL client billing: If you run a 3PL, Unleashed can’t invoice clients for storage, labour or services. Billing stays manual, and manual reconciliation leads to errors.
- No 3PL client portal: Clients can’t log in to see their own live stock levels or order status, so your team becomes the bottleneck for stock queries.
- Picking isn’t optimised: Pick lists aren’t routed, so pickers backtrack, and labour costs climb as volumes grow.
- Limited carrier and TMS connections: Shipping connections run through tools like Starshipit rather than the wide carrier and pallet network coverage of a dedicated WMS, and there’s no TMS integration.
- Mixed reviews on scanning and reporting: On Capterra, some users report gaps in barcode scanning and stock reporting.
WMS vs IMS: why the distinction matters
Understanding the difference between inventory management systems and warehouse management systems is important when choosing software.
Inventory management system (IMS), which is what Unleashed is: Tracks what you own, how much you have and where it’s located. It answers questions like “Do we have enough units to fulfil this order?” and “Which warehouse should this order ship from?” It’s built for visibility and stock control, not for directing the physical movement of goods.
Warehouse management system (WMS), which is what a 3PL needs: Directs the physical flow of goods through the warehouse: receiving, putaway, replenishment, picking, packing and despatch. A WMS answers questions like “What’s the fastest route for today’s picks?”, “Which pallet should this shipment go on?” and “Has the barcode been verified?” It’s built for operational efficiency and labour cost control.
In practice, many businesses run both: an ERP or inventory system (like SAP or Sage 200) holds stock and financial data, and a WMS (like Clarus) runs the warehouse floor. Unleashed covers the inventory side well, but it isn’t built to run a multi-client warehouse floor.
How Unleashed integrates with Clarus
If you want to keep Unleashed as your core inventory system but need a proper WMS on the warehouse floor, Clarus integrates directly with Unleashed. It’s a native connection, with no third-party middleware or coding required.
Running the two together, you keep Unleashed’s purchasing and financial tools and add Clarus’s picking routines, barcode verification and 3PL billing on the warehouse floor.
How the workflow operates:
- Order pass-through: Sales orders pass between Unleashed and Clarus with customer, address and line-level quantities, so your warehouse and finance teams work from the same data.
- Warehouse control: Your team allocates stock by exact quantity in Clarus, then runs wave picks, packs and prints shipping labels in Clarus, and the committed quantities pass back to Unleashed.
- Despatch sync: Once an order is despatched, Clarus posts the tracking and carrier details back to Unleashed, and stock levels update after picks and despatch.

How to choose the right Unleashed alternative
Ask yourself these questions:
- Are you a 3PL managing multiple clients? If yes, you need multi-client billing and client segregation. Look at Clarus, Mintsoft, Extensiv or Canary7. Unleashed can’t do this. Our guide to the Meilleur système de gestion d'entrepôt (WMS) pour les prestataires logistiques tiers (3PL) goes deeper.
- Do you need picking optimisation and labour cost control? If yes, you need a true WMS with wave picking and route planning, such as Clarus. Unleashed doesn’t optimise picking.
- Is ecommerce your main channel, with mostly parcel orders? Mintsoft is built around ecommerce fulfilment and Shopify and Amazon integration.
- Do you run a complex operation that needs tight ERP integration? Canary7 and Snapfulfil are both worth a look.
- Do you want a cloud WMS with a 3PL-focused feature set at a mid-market price? If yes, talk to Clarus.
