+# Money-Rails 3.0.0 Upgrade Prep
+
+**Date:** January 22, 2026  
+**Status:** Planned
+
+---
+
+## Summary
+
+Prepare to upgrade `money-rails` from 2.0.0 to 3.0.0. The primary breaking change in 3.0.0 is dropping Rails < 7.0 support, which this app already satisfies.
+
+---
+
+## Requirements
+
+- Ruby >= 3.1 (repo uses 3.4.7 via `.tool-versions`)
+- Rails >= 7.0 (repo uses ~> 8.1 in `Gemfile`)
+- Bundler 2.6.9 (required by `Gemfile.lock`)
+
+---
+
+## Preflight Checks
+
+```bash
+rg -n "money-rails" Gemfile Gemfile.lock
+rg -n "Monetize\\.extract_cents|extract_cents" app lib spec
+```
+
+Expected:
+- `Gemfile` uses `gem "money-rails", "~> 2.0"` before the upgrade.
+- No usage of `Monetize.extract_cents` (removed in Monetize 2.0).
+
+---
+
+## Upgrade Steps
+
+1. Update `Gemfile`:
+
+   ```ruby
+   gem "money-rails", "~> 3.0"
+   ```
+
+2. Update the lockfile:
+
+   ```bash
+   bundle update money-rails
+   ```
+
+   If bundler is missing:
+
+   ```bash
+   gem install bundler:2.6.9
+   ```
+
+3. Verify the lockfile shows `money-rails (3.0.0)`.
+
+---
+
+## Touchpoints to Verify
+
+- `config/initializers/money.rb` (MoneyRails configuration)
+- `app/models/concerns/*priceable*.rb` (monetize macros)
+- `app/helpers/currency_helper.rb` (Money formatting helpers)
+- Views that call `Money.new(...).format`
+
+---
+
+## Test Plan
+
+Run focused tests first:
+
+```bash
+bundle exec rspec spec/helpers/currency_helper_spec.rb
+bundle exec rspec spec/models/concerns/pwb/property/priceable_spec.rb
+bundle exec rspec spec/services/pwb/exchange_rate_service_spec.rb
+```
+
+Optional: full suite
+
+```bash
+bundle exec rspec
+```
+
+---
+
+## Known Breaking Changes
+
+- money-rails 3.0.0 drops Rails < 7.0 support (already satisfied here).
+
+---
+
+## Rollback
+
+Revert `Gemfile` and `Gemfile.lock` to the previous versions if issues arise.
