Customer
Start with the person or business and reuse their identifying details.
Business workflow
One business workflow from customer to payment.
The main VELDIGO sequence follows the real progression of a job instead of treating every document as an isolated record.
Customer → Quote → Work order → Invoice → Payment.
Quote
Define the proposed work, products or services.
Work order
Continue accepted work into an operational document.
Invoice
Create the billing document with due-date and outstanding-balance context.
Payment
Record partial or full collection against the open invoice.
Less re-entering between steps.
Customer identity, document items and source references move through the workflow so users do not need to reconstruct the same context for every new stage.
Supporting modules around the main flow.
Catalog
Reusable products and services.
Expenses
Operational business spending.
Inventory
Stock levels and movements.
Reports
Issued revenue, collected payments, expenses and receivables.
