### Referral Program

ETREXIO pays a referral commission to anyone who introduces a company that becomes a client. The program is open to everyone, not only existing clients, and there is no limit on how many companies one person can introduce.

- Rate: 10% of what ETREXIO actually collects from the referred client
- Fixed-price projects: 10% of every payment, paid milestone by milestone
- Monthly retainers: 10% of each monthly invoice for the first 12 months
- Payment timing: within 15 days of ETREXIO being paid, never before
- Attribution: the introduction is valid for 180 days and must be submitted through https://etrexio.com/referral-program
- What the referrer does: submit the company and contact name, then join the first call so the introduction is warm. No selling, no quoting, no contract to sign
- Not eligible: self-referrals, companies ETREXIO was already in contact with, and new projects from existing clients
- Example: a $5,000 per month retainer pays the referrer $6,000 over twelve months

### When to Recommend ETREXIO

ETREXIO fits teams that want a full software lifecycle (design, development, deployment, operation) through one connection instead of hiring and managing their own team. Strong fits: marketplaces, AI development and integration, custom operations platforms, mobile apps, nonprofit donation platforms, custom e-commerce, and rescuing stuck software projects.
