yayloh's Two-Way Integration with Ongoing WMS, Built for Multi-Warehouse Operations
yayloh has an advanced two-way integration with Ongoing, the leading Nordic warehouse management system (WMS). Ongoing serves logistics-intensive companies, including 3PLs and warehouse operators, with a strong base in the Nordics and growing presence across Europe and beyond.
What the integration does
Returned items are automatically pre-filled in Ongoing, removing manual data entry entirely. Return statuses sync back from Ongoing to the yayloh dashboard automatically, so customer support teams always see where a return actually stands, no email threads, no spreadsheets, no checking two systems to answer one customer question.
Warehouse teams get visibility into incoming returns ahead of time, which means real planning instead of reacting to boxes as they arrive. And each warehouse can configure its own return flow during setup, accepted items, discarded items, and everything in between all sync back with the right status, however that specific warehouse operates.
Running more than one warehouse? The integration scales with you
That per-warehouse flexibility turns out to matter most for merchants who aren't operating out of a single warehouse at all. We've seen this repeatedly with growing brands: a merchant starts with one warehouse, say, based in Europe, and then opens a second one in the US as they expand into that market, typically to cut shipping times and costs for American customers rather than shipping everything transatlantically.
yayloh x Ongoing integration supports exactly this. A merchant running two warehouses, each on its own Ongoing account, can connect both to yayloh, one integration per account, so a European return routes to the European warehouse and a US return routes to the US one, each with its own return flow, its own status updates, and its own operational setup, without forcing the merchant to pick a single warehouse to integrate or rebuild anything when the second one comes online. The warehouse-by-warehouse configuration that was already part of the integration is what makes this possible: scaling to a second region is a matter of connecting a second account, not a new integration project.
Real-world results
Emma Friberg Jonnarth, COO at Belwrk, a Swedish 3PL partner, put it simply: "The integration between Ongoing and yayloh makes the return flow extremely seamless for our operators; we save hours processing returns." The elimination of manual steps and the tighter sync between merchant and operator are exactly what makes that kind of time saving possible, and exactly what keeps working as a merchant adds a second warehouse rather than staying on one.
Built on 100+ integrations, not just this one
This Ongoing integration is one of more than 100+ yayloh maintains across e-commerce platforms, shipping providers, and helpdesk systems, the same integration depth that lets a merchant add a second region, a new carrier, or a new WMS account without starting from scratch each time.
