3PL Software UK: Fulfilment & Warehouse Software for Third-Party Logistics

3PL fulfilment software runs the warehouse operations of a third-party logistics provider: receiving, storing, picking, packing and despatching stock on behalf of client brands. It connects clients' sales channels, the warehouse floor and carriers in one system, keeps stock and orders separate by client, and tracks every order in real time from goods-in to delivery.

Yes. Keel is built by Planko Ltd, a company registered in the UK and headquartered in Altrincham, and is registered with the Information Commissioner's Office (ZB524558). Systems are modelled on your own warehouse and clients, with carrier integrations, built-in permissions and audit trails, and you can choose where your data is hosted, including the UK.

Keel supports API integrations with major eCommerce platforms including Shopify and Amazon, as well as third-party carriers and fulfilment tools. Stock levels, orders, and returns are synchronised in real time, eliminating manual reconciliation and ensuring your sales channels always reflect accurate inventory data.

Most customers go live in a matter of weeks rather than months. Keel's Build for Me service and Managed Migration offering mean the team models your process, configures the platform, migrates your data, and hands over full ownership to your team—with ongoing support throughout the transition to minimise any disruption to daily fulfilment.

Yes. Keel's warehouse management system supports multiple warehouse locations, with real-time inventory visibility down to the bin level across all sites. You can manage stock transfers between locations, set location-specific picking workflows, and maintain a full audit trail for every movement across your entire fulfilment network.

Unlike rigid off-the-shelf systems, Keel is built around your exact process — your warehouse layout, your terminology, your clients' rules and your exception handling. It's a code-first platform with version-controlled development, so your team can iterate on workflows without waiting months for a vendor update. You own the system completely, with no vendor lock-in.

Yes. Keel automatically generates internal tools for operations, customer service, and finance teams directly from your data schema. These include clean dashboards, real-time order and inventory views, SLA tracking, and custom reports—so every team member has the right data at the right time without needing technical support.

Keel is one fixed yearly subscription, billed in GBP with VAT added. It costs a lot less than a traditional ERP, and you won't need to double your budget for consultants to implement it. Because each system is modelled on your operation, the price is agreed after a conversation about your scope — contact the team at hello@keel.so for prices.

3PL software is a warehouse management system built for many stock owners rather than one. On top of goods-in, put-away, picking and despatch, it separates stock, orders and rules by client and captures the activity data needed to bill each client. A standard WMS assumes a single owner, which is why many UK 3PLs end up patching client billing with spreadsheets.

Yes. Because Keel systems are built on your own data model, stock, orders, returns and warehouse activity can be held by client, with client-specific picking and exception rules. Keel generates internal tools for operations and finance teams, giving client-by-client views and the storage, pick and despatch data you need to invoice each client accurately.

Through integrations built for your stack. Keel's fulfilment building blocks include carrier selection and carrier integrations, label printing, tracking sync and end-of-day closeouts, so your chosen UK couriers can be connected. Billing and invoice data can pass to accounting systems such as Xero or Sage through API integrations, built as part of your system rather than bought as off-the-shelf connectors.

Yes. Keel supports multi-region data residency: each environment has its own isolated infrastructure and database that can be hosted in a location you choose, including the UK. That matters for 3PLs holding clients' customer data, alongside Keel's ICO registration (ZB524558), deny-by-default access control and full audit log.

No. Keel is software only. Keel builds the operations software that UK 3PLs and in-house fulfilment teams use to run their warehouses, orders and carriers; it does not provide warehouse space, storage or fulfilment services. If you are looking for a 3PL to store and ship your products, Keel is not the right fit.

Yes. Keel is the trading name of Planko Ltd, a company registered in the United Kingdom at 3rd Floor, 1 Ashley Road, Altrincham, Cheshire WA14 2DT, with a team in London. Keel is registered with the Information Commissioner's Office under reference ZB524558, and payments are in GBP with VAT added.
