Tradebyte receives Shopify products, the stock set aside for each channel and the orders that come back, so one catalogue serves several marketplaces without a second product list to maintain.
Selling through Tradebyte means every channel wants the same product described its own way and, more awkwardly, wants stock it can rely on. A brand running Shopify usually solves that by giving each marketplace a share of the catalogue in a spreadsheet, then adjusting it whenever something sells faster than expected. The channels see figures that are hours old, orders arrive against stock already gone, and seller metrics suffer for reasons nobody can trace. The Shopify to Tradebyte integration keeps one catalogue and one live position, with each channel's allocation held deliberately.

Shopify products reach every Tradebyte channel from the same source, so a description corrected once is corrected everywhere instead of on whichever marketplace somebody remembers.
How much stock each Tradebyte channel may sell is set as a rule against the Shopify position, so a marketplace is never offered units another channel has already committed.
Orders raised on a Tradebyte channel arrive in Shopify as orders rather than as a report, so fulfilment works one list and nobody rekeys a marketplace sale by hand.
A new Tradebyte channel takes the Shopify mapping already in place, so trading somewhere new is a configuration change rather than another product feed to build.
A range is published from Shopify to a Tradebyte channel with the attributes that channel asks for, so a listing goes live complete rather than waiting on somebody to fill in the gaps the marketplace rejected it for.
Alumio applies the allocation rule you set to the Shopify stock position before it reaches Tradebyte, so a channel sells against the share it was given and a single fast seller cannot empty the rest of the business.
An order placed on a Tradebyte channel arrives in Shopify carrying the channel it came from, so it is picked and dispatched on the same run as the web orders and the marketplace is told about it the moment it ships.
Alumio sits between sales channels and fulfillment systems as a governed integration backbone. Orders are routed, transformed, and validated, while status updates return to every channel.
Authenticate your systems using Alumio's pre-built connectors. Choose from 200+ connector packages in the marketplace, plus unlimited custom integrations.
Define how data fields map between systems in a visual interface. Adjust formats, enrich records, and apply business logic, no custom code required.
Configure flows to run in real time on events, on a schedule, or both. Reduce manual data entry and let Alumio handle movement and transformation between systems.
Once your first integration is live, adding your ERP, PIM, WMS, or CRM connects to the same hub. Existing flows keep running. No rebuilding from scratch.
Returns are what most brands connect second, and they are the part of marketplace trading nobody plans for. A channel judges you on how quickly a return is settled, Shopify records the refund, and Tradebyte carries the channel's own expectations, so the handling service in between is the piece missing. Alumio holds that connection alongside this one, so a return is processed once rather than in three places.
It does, and the allocation is applied before anything reaches the channel. Alumio reads the Shopify position, applies the rule that decides how much each Tradebyte channel may sell, and publishes that figure rather than the whole quantity. Products and attributes travel on the cycle you choose, and orders come back as they are placed, so the two directions are timed for what each one actually needs.
No, this is configured rather than coded. The spreadsheet it replaces is the one where somebody keeps each marketplace's share of the catalogue and adjusts it by hand on a Friday. Which Shopify attributes feed which Tradebyte channel, and how much stock each one gets, are entries in the interface. Where a channel asks for something the catalogue does not hold in that shape, the Code Transformer derives it at that step.
As much as you can afford to lose to a cancellation, which is rarely the whole position. Sharing one Shopify figure across every Tradebyte channel maximises what is on offer and produces the cancellations that damage a seller rating, because two channels eventually sell the same last unit. Splitting it protects the rating and leaves stock unsold. Most brands split the fast movers, share the rest, and review it by season.
The marketplace counts a cancellation against you rather than against the integration, which is why a channel order arriving after its allocation has gone elsewhere is the expensive failure here. Alumio monitors each transfer live, records the Tradebyte channel and the quantity it carried, and raises an alert with the reason the moment Shopify cannot accept one. Retries run where configured, so nothing is quietly dropped.
