What it does

The Ereloonnota Skill automates the creation of professional fee proposals and interim billing statements specifically for architectural services. It transforms complex contract terms—such as fee percentages based on construction costs, hourly rates, and phase-weighted billing—into clear, transparent documents for clients.

Why use this skill

Architectural billing is notoriously prone to disputes due to shifting construction cost bases and phase-based progress. This skill ensures every calculation is transparently broken down, showing exactly how the fee was derived (Base Cost × Fee % × Phase %). It handles tricky scenarios like "more-work" adjustments, pro-rata billing for halted projects, and VAT regime checks, saving developers and architects hours of manual spreadsheet work.

Supported workflows

• Phase-based billing: Automatic calculation based on standard or custom project phases (e.g., Preliminary Design, Permit, Execution).
• Construction cost indexing: Adjusts billing when the budget shifts from estimate to tender.
• Hourly tracking: Integrates additional services outside the fixed fee scope with timesheet placeholders.
• Audit trail: Explicitly lists previously invoiced amounts to prevent double-billing.
