Feeds & Marketplace Syndication

Every channel wants your catalogue in a slightly different shape. Feed work is where margin quietly leaks, and where a week of engineering buys a permanent lift.

Feeds & Marketplace Syndication

The problem

Disapprovals and mismatches are costing you more than your bid strategy is

A feed that is 8% disapproved is 8% of your catalogue invisible on that channel, and it rarely shows up in a dashboard anybody reads. Title structure, GTINs, attribute mapping and stock sync all fail silently.

We treat the feed as a product surface in its own right: rules, monitoring and channel-specific optimisation rather than a nightly export nobody owns.

What you actually get

Every engagement ships these. No line items you cannot point at.

Channel-specific feed rules

Title, attribute and category mapping optimised per channel instead of one export reused everywhere.

Disapproval monitoring

Automated alerting on disapprovals, stock mismatches and price drift, with an owner and an SLA.

Margin-aware segmentation

Feed labels that let bidding separate hero lines, thin-margin lines and clearance instead of averaging them.

Sync reliability

Stock and price sync frequency raised to match how fast your inventory actually moves.

How we run it, week by week

Week 1

Feed diagnostic

Every channel audited for disapprovals, mapping errors and title structure against category norms.

Week 2

Rule build

Channel rules, labels and segmentation built and validated on a sample before full push.

Week 3

Monitoring

Alerting and a weekly health report wired up, with thresholds agreed with your team.

Ongoing

Managed feeds

We hold the rules, respond to channel spec changes, and report monthly on coverage and margin mix.

Stack we work in

Platform-agnostic. We work in whatever you already own and tell you honestly when it is the constraint.

Questions buyers ask us

Typically a few hours for access and one data export. The rules live in the feed layer, not in your storefront code.
