Contracts, warranty & depreciation

Contracts (warranties, support, leases, licences, subscriptions) hold kind, vendor, owner, dates, cost and billing cycle, seats, auto-renew, notes, linked assets and documents. Each day, expired active contracts renew by their billing cycle or expire, and owners get renewal reminders 60, 30 and 7 days ahead. Depreciation runs per type — straight-line or double-declining balance, with per-asset life and salvage overrides — and shows as book value plus schedule on the asset, in the dashboard, reports and exports.
