Core Invoice Functionality
Build the heart of your invoice generator by creating the database models, user interface, and server logic needed to create and manage invoices. Develop client management capabilities and establish the complete workflow from invoice creation to client relationship management.
Invoice Models, Forms & Creating Your First Invoice
Design and implement the Prisma database models for invoices, line items, and related data structures. Build the invoice listing page to display all user invoices and create a comprehensive invoice creation form with dynamic line items, tax calculations, and client selection. Develop server actions to handle invoice creation, validation, and database operations, culminating in successfully creating your first fully functional invoice within the application.
Invoice Details, Client Management & Production Deployment
Complete the invoice workflow by building a detailed invoice view page with edit capabilities and professional formatting. Implement a client management system including a client listing page and detailed client profiles with contact information and invoice history. Integrate client data throughout the invoice creation process, then deploy all new features to production, ensuring your invoice generator is fully operational with complete CRUD functionality for both invoices and clients.
