Offline-first is not a feature here, it is the architecture
A finance app that shows a spinner when the signal drops is a finance app people delete. The pattern that works is a local database as the single source of truth, writes that land locally and sync afterwards, and a UI that reads only from the local store and never from the network. That is a decision made on day one — a cloud-first app cannot be made offline-first by adding a cache.
Where the money numbers usually go wrong
Storing amounts as floating point is the recurring bug in this category: 0.1 plus 0.2 is not 0.3, and a rounding error compounds across a month of transactions until a balance disagrees with the sum of its rows. Store minor units as integers. Check which one a template does before you trust it with someone's budget.
