Arcal

ARCAL is Binny's internal payment collection and gold rate calculator app, built for staff to quickly compute jewellery bills using live gold rates.

Key features:
• Live Gold Rate — real-time 999 and 995 purity gold rates, updated continuously, with configurable variance tolerance.
• Multiple Billing Methods — support for Fixed Gold, Unfixed Gold, and Unfixed Money billing methods to match how each client is invoiced.
• Purity Converter — convert weight between different gold purities (e.g. 22K to 24K) using standard fineness ratios.
• Client & Method Tracking — save calculations and billing methods per client for quick reference.
• Secure Login — staff sign in with authorised credentials; sessions can be remembered for up to 7 days.
Access to this app is restricted to authorised Binny's staff only. It is intended for internal business use in payment collection and gold rate calculations, not for public trading or investment purposes.
