Plan the first market and the next one
A product can share its core workflow across markets while needing different billing, language, time-zone and support settings. Discovery should identify the first customer market, the currencies you intend to charge in and the merchant accounts available to your business. Hosting and data-handling requirements also belong in that discussion.
What to prepare for your project
Bring your launch market, expected customer locations and payment requirements to scoping. We can distinguish the features needed for launch from those that can follow in a later release.
