Who we are

LaGuiaEmprendedor is an editorial and software project built by Omenius, a development studio based in Ecuador. Our team combines first-hand experience in Ecuadorian accounting, IESS payroll, SaaS startup finance, and web development. We publish free calculators because for years we ended up rebuilding the same spreadsheets again and again for small clients who could not afford accounting software. We decided to open the math and the source rather than license it privately.

What we solve

Every calculator we publish solves a real problem we lived ourselves or a client asked us about. We do not add tools to inflate the catalog: each slug comes from a conversation with a founder who could not find the answer online. So we prioritize:

  • Ecuador payroll and tax (employer IESS, 13th and 14th salary, 15% profit-sharing, SRI proforma invoice).
  • SaaS and startup metrics (burn rate, runway, MRR, churn, CAC/LTV, scorecard valuation, break-even, ROI, freelance rate).
  • Solo founder finance (PayPal / Stripe / MercadoPago fees, currency conversion, French and German amortization, compound interest, personal dashboard).
  • Productivity utilities (bulk QR generator, word counter, password generator, slug generator, UTM builder, SRI XML viewer).

How each calculator is built

Each piece of logic lives in a pure TypeScript module with automated Vitest unit tests. That means:

  1. Every formula is documented in source.
  2. Every edge case (zero division, decimals, banker rounding) has a test that runs before each deploy.
  3. Legal constants (Ecuador SBU, IESS rates, VAT per country, PayPal fees per region) are versioned per year and reviewed annually as authorities publish updates.
  4. Every reference-only calculator carries a visible disclaimer: "Reference calculation. Verify with the relevant authority."

Why it is free

The free tier will always remain free. Our planned business model adds:

  • A Pro tier with server-side tools (image compression, OCR, PDF merge, contract templates) that cannot run in the browser.
  • Non-intrusive advertising (Google AdSense) that funds maintenance.

We do not sell data. We have never sold data. Analytics is cookieless and aggregate (Plausible). Calculators run 100% in your browser; our servers do not see the values you enter.

Editorial

Explanatory text, FAQs and examples are written by the same team that codes the math. When a legal change affects a constant (for example when Ecuador raises the SBU in January), we update the constant in code first and the copy second. The last-updated date lives on every calculator.
