Complete guide to Costes Consulting
Getting started
Sign up at costes.consulting to receive 50 free credits with no card required. Describe your project in your own words: the more information you give (floor area, type of work, finishes, location), the more accurate the budget will be. When you submit the request, the AI analyzes the project, looks up current prices and generates a budget structured into professional chapters (demolition, masonry, installations, etc.) using the PREOC 2026 price base with official NTE descriptions. Everything runs in the browser, with sessions and budgets synced to the cloud across your office computer, your on-site laptop and your phone.
Use cases
Quick estimate for a client
You describe the project in free text and, within minutes, get a budget by chapter with up-to-date market prices, useful for a first estimate before the detailed design (proyecto ejecutivo).
Compare line items against official prices
The AI selects line items from the PREOC 2026 database with their prices and NTE descriptions, which serves as an objective reference against contractor quotes.
Work from any device
Because it runs 100% in the browser and syncs to the cloud, you can start a budget in the office and review or adjust it from your phone on site.
Advanced setup
- Credit systemThere is no monthly subscription: you pay for credits that are consumed per budget generated (100 credits = €10), starting with 50 free credits when you sign up.
- Level of detail in the descriptionThe accuracy of the budget depends directly on how much information you include in the project description: type of work, floor area, finishes and location.
Tips
- Use the 50 free credits to test with a real project before buying more credits.
- Include floor area, location and finish quality in the description to reduce the budget's margin of error.
- Use the generated budget as a starting point and cross-check it against at least one real contractor quote.
