Overview

Tremo is warehouse and fulfilment software for webshops, B2B businesses, warehouses and third-party logistics providers. It suits teams that need inventory, picking and shipping workflows in one system, particularly when they serve multiple clients. The free plan offers a low-commitment way to start, but its pick-list cap and paid overage make costs worth watching as volume grows.

Key features

Picking and inventory

Teams can scan items to pick, use a camera to read barcodes, or combine open pick lists into a batch round. Batch picking can consolidate warehouse work; scanning helps confirm items during picking. Tremo tracks available stock and reservations and syncs stock to connected sales channels, linking warehouse activity with channel inventory.

Warehouse and shipping workflows

Multiple warehouses, location management and purchase orders support operations beyond a single stockroom. Tracking batches, expiry dates and serial numbers adds useful inventory detail for teams that need it. Carrier rules route shipments by client, country, weight, cutoff and tags, while the packing flow supports labels and tracking.

Sales connections include Bol, Shopify, WooCommerce, Lightspeed and CCV Shop; shipping connections include PostNL, DHL Parcel and MyParcel. The open API covers orders, stock, shipments and products and uses an API key. That gives teams an integration route beyond the named connections, though the API scope described is limited to those areas.

3PL operations and controls

Multi-client operations and a client portal make Tremo relevant to fulfilment providers. It can tally customer activity into monthly draft invoices and pass carrier costs through after matching shipment lines, addressing two recurring parts of 3PL billing. The maker says customer data is separated at database level, actions are searchable in an audit log, and data can be exported or moved at any time.

Pricing

Tremo has a free plan and no free trial. Free costs € 0, covering 100 completed pick lists per month; each additional pick list costs € 0.26. Access starts without a credit card or commitment, but there is no human support at this level. It is a practical starting point for low-volume operations, not an unlimited free tier.

Growth costs €329.00 per month and includes 3,000 pick lists, with extra pick lists charged at € 0.24 each; the rate can fall by volume to € 0.095. It fits teams that have outgrown Free and need a larger included allowance. Fulfilment costs €715.00 per month, also includes 3,000 pick lists, and charges € 0.22 per extra pick list, with the rate dropping by volume to € 0.095. Its higher base price is aimed at fulfilment workflows rather than simply a larger included quota.

Enterprise / 3PL has custom pricing under an annual contract, for large fulfilment companies needing custom integrations and setup. Free hosting is in the EU, with data stored separately per customer. The contact page says users can write directly to the people building Tremo and hear back within one business day.

Platforms

Tremo supports API, iOS, macOS, web and Windows. Its iOS app is for warehouse use; its Mac and Windows desktop app runs in the system tray and pairs a workstation for printing.

Who it's for

Tremo is a good fit for warehouse teams and webshops that need connected stock, picking and shipping workflows, and for 3PLs that need multi-client operations and billing support. Teams with very low pick volumes can begin on Free; those with sustained volume should weigh per-pick-list charges against the paid plans. It is less suited to buyers who require a free trial or human support on the free tier.

Pros and cons

Pros: Scan-based and batch picking, inventory sync, and shipping rules bring core fulfilment steps together.
Pros: Client activity tallying and carrier-cost pass-through support 3PL billing workflows.
Pros: An open API, named channel and carrier connections, and exportable data offer integration and data-mobility options.
Cons: Free is limited to 100 completed pick lists monthly, then € 0.26 per extra list, and has no human support.
Cons: There is no free trial, and Growth and Fulfilment both include 3,000 pick lists despite their different monthly prices.

Alternatives

Consider Third-Party Logistics Software to compare options across the category. Choose Brilliant WMS if a smaller-scale warehouse operation needs basic functions and prefers month-to-month SaaS or an on-premise option. Infoplus 3PL WMS is another paid WMS option, with Android, iOS, web and API support. Storely may suit teams looking for a paid platform with a free trial and priced add-ons for warehouses and clients. Azuvio WMS is worth considering for a lower stated starting price, with scanner hardware purchased separately. CoreIMS offers a 15-day free trial in a secure test environment with sample data. Shipedge describes a startup plan for low-to-mid volume, with channel automation and multiwarehouse support. ShipHero WMS may suit brands seeking a standard WMS plan with returns, automation rules and setup and training. Logiware is an alternative with seat-based pricing and no per-transaction charges.

Verdict

Choose Tremo if your warehouse or 3PL needs inventory, picking, shipping and client billing workflows alongside an open API. Its free tier lowers the barrier to trying a small operation, but the 100-list cap and paid overages matter quickly as volume rises. Look elsewhere if you need a free trial or want to avoid per-pick-list pricing.
