The ECP is a PHP-based system designed for optical clinics and medical practices to manage pricing, payments, and financial transactions. A core feature is the pricing calculator, which determines costs for frames, lenses, coatings, and tints based on retail price, benefit coverage, and tax rates. Major updates include refining tax calculations, integrating unique identifiers (IIDs) for accurate data tracking, and ensuring compliance with VSP plan requirements. Additionally, the system now automates invoice calculations and dynamically manages custom add-ons to prevent pricing inconsistencies.
