For a carpets store, the current fixed deposit feature needs to be more dynamic. We need line-item integration that calculates costs based on variable units (like square meters or linear feet), not just fixed amounts. The estimate should include a mandatory field to link to the specific carpet roll/SKU for accurate inventory management. Finally, the system should allow for automated status change (e.g., from 'Accepted' to 'In Production') upon deposit payment, streamlining the production process for custom flooring jobs.
