What is Colly.io and who is it for?

Colly.io is a cloud-based multi-tenant SaaS platform for e-commerce fulfillment and multichannel order management. It is ideal for online retailers, multichannel sellers and fulfillment service providers who want to efficiently manage orders from multiple channels in a single interface.

Which sales channels are supported?

Currently supported: Amazon (Seller Central), eBay, Kaufland, netto-online, Shopify and WooCommerce. Each channel can be configured independently with its own credentials, mappings and shipping profiles.

How does inventory management work with multiple locations?

Colly.io supports any number of warehouses with independent inventory management. Stock levels, reservations and goods receipts are managed per warehouse. Goods receipts can be recorded via barcode scan. All movements are logged in a revision-proof audit trail.

Is there a DATEV integration?

Yes. Colly.io exports DATEV-compatible CSV files (journal entries, accounts, tax keys). ZUGFeRD invoices (PDF + XML) are also supported. All documents are archived in a GoBD-compliant and revision-proof manner.

How are returns managed?

Colly.io provides a structured RMA process: Announced → Label created → In transit → Received → Inspected → Restocking or disposal → Completed. Return labels can be generated via DHL and UPS - the entire process is logged with an audit trail.

What happens when my subscription expires?

In case of payment default, the account switches to a restricted read-only mode. You can still log in and view invoices, but cannot perform any actions. After successful payment, full access is automatically restored.

Multi-Channel Fulfillment Platform

All channels. One system. Full control.

Colly.io consolidates orders from Amazon, eBay, Shopify and more into a single interface - with inventory, shipping and accounting directly integrated.

5.0 out of 5 stars

Built for online retail

Four things that make the difference when you sell across several channels.

One place for every channel

Amazon, eBay, Kaufland, netto-online, Shopify and WooCommerce – every order arrives here instead of in six different back ends.

Never sell the same item twice

Stock is reserved across every channel the moment an order arrives - before the next buyer can get to it.

Your accountant gets what they need

DATEV export, GoBD archiving and e-invoicing are built in, not bought in.

Your first channel is live in ten minutes

Enter the API credentials, check the mapping, done. Orders you already have are imported retroactively during setup.

What our customers say

Colly.io helps e-commerce teams of every size simplify their fulfillment process.

“Finally a system that truly brings all channels together. No duplicate bookings, no data chaos - Colly.io does exactly what it promises.”

Laura K.

“The DATEV integration was the deciding factor for us. GoBD-compliant archiving without extra effort - that was unthinkable with our old solution.”
