Overview

Tremo brings stock control, fulfilment workflows and billing together for warehouses, webshops and 3PLs. Multi-client operations and a client portal support providers serving several customers, while integrations and an open API connect warehouse work with sales and shipping systems. The product is built by a Dutch software team at Afiant Commerce BV.

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-picking round. Batch picking can consolidate work across orders; scan-based picking supports item confirmation during fulfilment. Tremo tracks available stock and reservations and syncs stock to connected sales channels, helping keep channel inventory aligned with warehouse records.

Warehouse operations and shipping

Multiple warehouses, location management and purchase orders support operations beyond a single stockroom. Tracking batches, expiry dates and serial numbers is useful when products need more detailed identification. Carrier rules can route shipments by client, country, weight, cutoff and tags; packing supports carrier labels and tracking.

Named sales connections include Bol, Shopify, WooCommerce, Lightspeed and CCV Shop; shipping connections include PostNL, DHL Parcel and MyParcel. The open API, accessed with an API key, covers orders, stock, shipments and products. That gives teams another route to connect systems, though it does not establish which custom integrations are included in each plan.

3PL billing and data

For fulfilment providers, Tremo can tally customer activity into monthly draft invoices and pass carrier costs through after matching shipment lines. That can bring operational activity and shipping charges into the billing workflow, rather than leaving both to manual reconciliation. The maker says customer data is separated at database level, actions can be searched in an audit log, and data can be exported or moved at any time.

Pricing

Tremo has a free plan and paid plans from € 329 per month. There is no free trial; the demo page says access starts without a credit card or commitment. The free listing says hosting is in the EU and data is stored separately per customer.

Plan	Price and allowance	Best fit
Free	€ 0; 100 completed pick lists/month, then € 0.26 per additional pick list. No human support.	A small operation validating a workflow or handling low monthly volume.
Growth	€ 329 per month; 3,000 pick lists included, then € 0.24 per extra pick list, with the extra-list rate dropping by volume to € 0.095.	A growing warehouse that needs paid access and expects regular picking volume.
Fulfilment	€ 715 per month; 3,000 pick lists included, then € 0.22 per extra pick list, with the extra-list rate dropping by volume to € 0.095.	A fulfilment operation weighing the higher base fee against its lower initial extra-list rate.
Enterprise / 3PL	Custom pricing; annual contract, custom integrations and setup for large fulfilment companies.	Large providers needing tailored integrations and setup.

The Free plan’s 100-list cap is a real operating constraint: beyond it, each additional completed pick list costs € 0.26, and there is no human support at this level. Growth and Fulfilment each include 3,000 pick lists, but Fulfilment costs more while lowering the initial overage rate by € 0.02 per list. The extra-list rate on both paid plans drops by volume to € 0.095; teams should weigh that usage pricing against the fixed monthly charge. No seat limits are stated for these plans.

Platforms

Tremo supports API, iOS, macOS, web and Windows. The iOS app is for warehouse use. Its Mac and Windows desktop app runs in the system tray and pairs a workstation for printing, which is useful when printing is part of the packing station workflow.

Who it's for

Tremo is most compelling for warehouses and 3PLs that want picking, inventory, shipping and fulfilment billing tied together, particularly where multiple warehouses or client accounts are involved. Webshops and B2B operations can also benefit from stock syncing and the named shop connections. It is less suitable for a team that needs human help on the free tier or cannot predict pick-list volume well enough to budget for per-list charges.

Pros and cons

Broad fulfilment coverage: picking, inventory, shipping and monthly draft billing sit within one system, reducing the need to split those workflows across separate tools.
Useful warehouse detail: multiple warehouses, locations, purchase orders and batch, expiry-date and serial-number tracking suit more involved stock operations.
Free entry point with a firm ceiling: 100 completed pick lists per month is enough for a small operation to start, but additional lists cost € 0.26 and human support is excluded.
Paid plans still meter volume: Growth and Fulfilment include 3,000 pick lists, then charge per extra list, so high-volume teams must account for usage as well as the monthly fee.

Verdict

Choose Tremo if your warehouse or 3PL needs connected inventory, picking, shipment handling and customer fulfilment billing, with multi-client workflows and a free way to begin. Its main trade-off is metered pick-list volume: the free tier stops at 100 lists before charges begin and has no human support, while paid plans still bill overages. Teams with unpredictable or heavier volume should compare that ongoing cost with a custom-priced enterprise contract or another paid option.
