Buying and running software in the United States
US enquiries divide fairly cleanly into two shapes. Founders want a narrow first version they can put in front of users and change weekly. Established service businesses — clinics, repair shops, property managers — want to replace a tool they already pay for, and arrive with a list of what the incumbent gets wrong. The second group cares more about migration of existing records than about the feature list.
Payments are card-first. Stripe is the default, and the interesting work is rarely the checkout itself: it is subscription state, proration, failed-payment recovery and the webhook handling that keeps an account's access in step with its billing status. ACH via Plaid comes up where invoice sizes make card fees material.
Tax is sales tax by state rather than a single national rate, and economic nexus means the rules follow where customers are, not where the business sits. Rates are pulled from a tax service rather than hard-coded, because they change without notice.
Two compliance items surface often enough to plan for. Sending SMS requires A2P 10DLC brand and campaign registration before traffic flows, which has lead time. Anything touching patient data raises HIPAA questions that decide the hosting and logging design, so they are settled during scoping rather than after.
Hosting is usually AWS or a managed platform the business already uses.

Replacing an incumbent tool makes data migration the first milestone, not the last. Exports from the existing system are profiled early, because they reveal the records that do not fit the assumed model — the half-finished jobs, the customers with two addresses, the historical entries nobody wants to lose. Scope, source code and handover terms for the agreed modules are set in the written agreement.
