Where the budget actually goes

A catalogue with straightforward products and one warehouse is a short project on any modern platform. The same catalogue with configurable products, multiple stock locations, a legacy stock system and country-specific tax rules is a different project entirely, and the storefront is perhaps a fifth of it.

Ask candidates to price the integrations separately from the shop. If a supplier cannot split the number, they have not thought about it, and the number will move.

Operations outlive the launch

The people who will live with this build are in the warehouse and in customer service, and they are rarely in the room. Find out how an order that goes wrong is corrected, how a refund is issued, and how somebody edits a product at eight in the morning. A build that is elegant and unusable by the people who run it is a failure that takes six months to admit.

The strongest suppliers ask to speak to those people during discovery. Treat that as a good sign rather than as scope creep.

Rates you will hear

Hourly bands commonly quoted in the city. Integration work is usually the largest single line in a serious build and the one most often underestimated at proposal stage.

Signals worth checking

Integrations scoped separately: Each system named, each direction of data flow named, each failure case named.
A migration plan for the catalogue: Including the products nobody wants to talk about: discontinued, variant-heavy, badly photographed.
Someone has run a peak: Ask what broke during a sale and what they changed afterwards.
Back-office thinking: Evidence that they have designed for the person issuing a refund, not only the person buying.
A rollback that has been rehearsed: Deploying on a Friday is a policy question. Being able to undo it is an engineering one.

Ask before you sign
