UFT (Ultra Fast Track) measures how much of a brand’s selection is available for the fastest delivery options — same-day or next-day handling — based on where the inventory is actually held.

What is UFT?

UFT (Ultra Fast Track) measures how much of a brand’s selection is available for the fastest delivery options — same-day or next-day handling — based on where the inventory is actually held.

It answers a placement question as much as an availability one. Stock of the same product can be buyable in one location and ineligible for fast delivery in another, so the metric reflects how well inventory is distributed across the network relative to where the demand is.

What drives the number

Three factors. Where the inventory sits, since fast delivery requires stock positioned close to the customer. How reliably it is replenished, because a location that keeps running dry cannot sustain fast eligibility. And network balance — how well the distribution across facilities matches the pattern of demand.

The commercial consequence is direct: fast-track eligible products win the sharpest delivery promises, and delivery promise is one of the strongest conversion levers on a listing. A product that is available but slow converts worse than the same product available quickly.

Improving it in practice

Three moves. Review the metric product by product rather than in aggregate, so that specific selection gaps are visible. Adjust inbound distribution towards the locations serving the strongest demand, which is a planning decision rather than a marketing one. And keep replenishment reliable at those locations, since fast eligibility lapses quietly when stock runs out and takes time to rebuild.

Where the metric is low across a whole catalogue, the cause is usually a distribution pattern that was set once and never revisited. Demand moves geographically; inventory plans often do not.

In practice

A brand reviews ultra-fast availability by product, finds two of its best sellers concentrated in a single location, and shifts inbound allocations towards the regions generating most of the demand. Fast-delivery share rises, delivery promises tighten, and conversion follows on both lines.

How Harpy Media helps

Inventory placement is part of our operations work: fast-delivery availability reviewed product by product, inbound allocation aligned to demand, and delivery promises protected as a conversion lever.

UFT FAQ

What is UFT?

Ultra Fast Track — the share of a brand’s selection available for the fastest delivery options such as same-day or next-day handling, determined by where the inventory is held.

What affects it?

Inventory location across the network, replenishment reliability at those locations, and how well the distribution of stock matches where demand actually is.

Why does it matter?

Because fast delivery promises convert. A product that is available slowly competes poorly against the same product available quickly, even at the same price.
