Project Overview
AutónomosPro is a multi-tenant SaaS product built around the recurring administrative work of Spanish autónomos and small businesses. It connects customers, products, quotes, invoices, expenses, payments, tax records, portals, licensing, and regulatory controls in one platform.
Project Context
The situation
A grounded view of the business context behind the project without inventing vanity metrics.
Why this matters
These case studies are intentionally commercial rather than theatrical. The point is to show how clearer digital structure can improve trust, handling, and market position.
01
Spanish freelancers often manage customers, quotations, invoices, expenses, and taxes across several disconnected tools
02
Invoice calculations and regulatory requirements need dependable rules and traceable records rather than manual document editing
03
Different businesses and advisers require separate organisations, user roles, feature access, branding, and secure data boundaries
04
The product needed to support recurring billing, digital acceptance, customer communication, and self-service portals
05
AI and automation needed to reduce repetitive administration while financial and compliance decisions remained controlled
What was built
The practical system, content, and structure decisions that shaped the project.
01
Multi-tenant invoicing and CRM
Organisations manage their own customers, products, services, quotations, invoices, payments, and recurring billing inside isolated accounts.
02
Spanish tax and invoice workflows
IVA, IRPF, expenses, supplier records, tax reporting, invoice integrity, fiscal QR codes, and VeriFactu-oriented controls are built into the platform model.
03
Quotation and customer journeys
Detailed quotations, digital acceptance, conversion to invoices, branded documents, email delivery, and customer portal access form a connected commercial workflow.
04
Adviser, licensing, and subscription layers
The system supports advisers, multiple client organisations, configurable licence tiers, feature access, trials, subscriptions, and platform administration.
05
AI-enabled administration
AI integration and workflow automation assist repetitive administrative work while structured platform records remain the source of truth.

Strategy and implementation
Turning the brief into a useful digital product
The decisions below connect the commercial objective to the structure, content, and user journey of the finished project.
01
Model the full admin cycle
The platform connects the journey from customer and quotation through invoice, payment, expense, tax, and reporting instead of solving only document generation.
02
Compliance in the core
Invoice integrity, tax calculations, fiscal identifiers, QR codes, records, and submission-oriented workflows are treated as system responsibilities.
03
Serve distinct roles
Business owners, staff, advisers, customers, and platform administrators receive interfaces and permissions suited to their responsibilities.
04
Automate repeatable work
Recurring billing, email delivery, PDF creation, reminders, imports, portals, and AI assistance reduce repetitive administration around reliable source data.

AI-assisted capabilities support administrative workflows and automation, while financial records and compliance-sensitive actions remain governed by structured application logic.
