Why Eternity

Buying technology shouldn't be a leap of faith

  • A firm-price quote within 24 hours. Scope defined and agreed before signing; the project doesn't change halfway through.
  • Everything stays in your name. Your domain, your store accounts and your source code. No hostages.
  • You pay against results you can see: a working demo before the middle payment and approved publication before the final one.
  • One accountable company. Eternity LLC, with a contract and a 60-day bug-fix warranty after launch.
  • Direct support from the team that built your website or app, in Spanish and English, with response times defined in each plan.
  • 100% remote. Demos and progress you can check on your phone, wherever you are.
Ongoing support

After launch, you're not on your own

Publishing is only half the road. Your website or app stays on a support plan so it keeps working and growing with you.

  • Maintenance kept current: updates, security and backups included in your plan.
  • Guidance in Spanish and English, by email and WhatsApp, from the team that built your project.
  • A 60-day bug-fix warranty after launch, in writing in your contract.
  • Training for you and your team, so you can use everything without depending on anyone.
  • Improvements and new features as your business grows, quoted before we build them, always with your approval.
  • Your AI agent can be added whenever you need it; for apps, the option is presented in your quote.

Common questions

Frequently asked questions

How long does my project take?

Websites take 1 to 3 weeks and apps 4 to 16, depending on the level. Your quote states the timeline before you sign.

Does everything stay in my name?

Yes: your domain, your store accounts and, at final payment, the complete source code of your app. Under the rental option, the app lives under Eternity's accounts while the service lasts, with a purchase option from month 12.

How do I pay?

In milestones, against deliverables you can see: for apps, 50% at signing, 25% with the working demo and 25% against approved publication. For websites, 50% upfront and 50% against the published site. Subscription products are paid monthly.

What do I need to get started?

Your logo, your texts and your photos. If you're missing any content, we'll sort it out together in the quote.

What if a store rejects my app?

If the rejection is over something fixable within the agreed scope, we fix it and resubmit at no cost until it's approved.

Can my app have artificial intelligence?

Every app we build has the option to integrate artificial intelligence; the details are presented in your quote.

Do you work with businesses outside the United States?
