Publishing on multiple marketplaces and channels?
Flow by WhatSales

Multichannel mass publishing, simplified.

Flow is a centralised publishing engine for creating, updating and managing product listings across multiple sales channels — quickly and accurately. One product record in, marketplace-ready listings out.

One product.·Many marketplaces.·Total control.
What’s inside Flow

Flexible Product Import Engine

Get products in three ways: import existing listings from another marketplace with AI, upload a CSV, or build from scratch in Product Studio.

Import · CSV · Product Studio

Unified Master Catalogue

One master product record sits behind every channel. Flow reshapes it into whatever each marketplace expects, so your data stays consistent everywhere.

Single source of truth

Channel-Native Content Studio

Titles, bullets, descriptions, images and attributes are built for each marketplace — not copy-pasted from one listing to the next.

Per-channel optimisation

Intelligent Mapping Assistant

Flow maps the category and product type for each channel and loads the right field set. You approve it or change it — nothing publishes behind your back.

Guided mapping

Proactive Listing Validation

Errors are caught before you publish. Validation flags missing fields, warnings and rule breaks up front, so you fix them while the listing is still yours.

Green status

Real-Time Sync & Global Control

Live status across Amazon, eBay, Shopify, Walmart, Etsy, TikTok Shop, Temu and more. See what is live or failed, change it once and push it everywhere.

Step 3 · Choose your route

Amazon and other marketplaces

The setup is shared. The publishing rules are not.

Amazon publishing

UK first

Fulfilment and regions are part of the flow.

  • 1
    Map the Amazon categoryFlow suggests it — you approve or change.
  • 2
    Select the product typeLoads the right field set.
  • 3

  • 4

  • 5

  • 6
    Publish on Amazon UKOther regions follow, auto-translated and reviewed.
Amazon rule

Publish on Amazon UK first. Other Amazon regions follow only after the UK listing is accepted.

Other marketplaces

Publish direct

Every channel keeps its own rules and settings.

  • 1
    Select the marketplaceTemu, eBay, TikTok Shop or another connected channel.
  • 2

  • 3

  • 5

  • 6

Key difference

No FBA or FBM. Each channel uses its own stock and delivery settings, and publishes straight to the selected region.
