The catalogue is the easy part.

iLeaf builds commerce products and the operations behind them — multi-vendor marketplaces with seller onboarding, product Q&A and ratings, mobile applications for existing and new customers, and the inventory and field systems retailers depend on. The same field operations practice — the one behind AIMS, built for CALM IPSUM Group LTD — connects what is on the shelf to what the system believes is there.

What this includes

Multi-vendor marketplaces
Seller registration, listing and payout flows, so a catalogue can grow without the operator keying it in.
Mobile commerce
Native applications for iOS and Android where the measure is completed checkouts, not installs.
Product Q&A and ratings
Buyer-to-seller interaction that answers the question standing between a shopper and a purchase.
Inventory & field operations
Store and depot systems reconciling physical stock with the record, from the same practice serving grocery retail.
Recommendation engines
Ranking that reflects margin and stock position, not only what a shopper looked at last.
Conversational commerce
Voice and chat assistants that answer product questions and hand over cleanly when they should not guess.

How we run it

Every phase ships something usable on its own, so you are never holding a half-finished system waiting on the next milestone.

  1. Optimise for the completed order

    Sessions, installs and time-on-page are proxies. The number that pays for the project is completed orders, and that is what gets measured.

  2. Let sellers self-serve

    Marketplace growth stalls when every listing passes through the operator. Onboarding is built so the catalogue can grow without headcount.

  3. Peak is the design case

    Retail traffic is not uniform. The architecture is sized for the sale day, because that is the day the business is judged on.

  4. Never fake stock

    Selling something unavailable costs more than a missed sale. Where inventory is uncertain the interface says so.

Questions we get asked

Do you build marketplaces or only single-vendor stores?

Both, and marketplaces are the harder and more common request. That includes vendor self-registration, listing management and payouts, plus the buyer-side features that make a marketplace work — product questions answered by sellers, and ratings that carry enough signal to be worth reading.

Can you work with our existing platform?

Usually yes. Most retail engagements extend something already trading rather than replacing it, because a replatform during a working year is a risk few retailers should take. We would rather add the marketplace, mobile or recommendation layer alongside what runs today.

How do you handle peak traffic?

By treating the sale day as the design case rather than an exception. Capacity, caching and queueing are sized for peak from the start, and load is tested against it before the season rather than discovered during it.
