Contalia

Accounting and invoicing software designed to comply with the Spanish Tax Agency's VeriFactu regulation.

Online demo in preparationI want something like this

The problem

The VeriFactu regulation requires SMEs and freelancers to issue invoices with a specific format and traceability. Existing solutions are expensive or overly complex.

The approach

Built on .NET 10 and Blazor with a domain layer focused on regulatory compliance: invoice chaining, immutable records and compliant export. Persistence in PostgreSQL.

Highlights

Compliance-oriented data model (chaining and traceability)
.NET 10 + Blazor stack for a single web codebase
Focused on SMEs/freelancers: simple outside, rigorous inside
