Chalmsy is business management software that automates proposals, invoicing, bookkeeping, and client management for service-based businesses. Powered by fronteir AI, it learns from business documents to replicate voice, pricing, and style without technical setup. The platform centralizes client interactions, proposals, invoices, and financial records in one dashboard. It drafts branded proposals with tiered pricing, tracks inquiries through a booking pipeline, and auto-generates invoices from proposals for consistency. Users can photograph receipts for AI extraction of details, feeding live profit and loss statements. Integration with Google Calendar and Gmail streamlines scheduling and communication. Role-based access controls enable team collaboration while restricting financial data visibility. Custom branding applies to the interface and client documents, and period locking secures closed accounting periods.
