Before there is a business

Starting Out

A first client, a side project, a hobby that started paying — you do not need a company to run it properly. Start free, invoice like a business, and grow into one when you are ready.

You Have a First Client. That Is Enough.

Most business software assumes you already have a business. EternalEngine assumes you are about to.

The Side Project That Started Paying

A friend asked you to build their site, fix their deck, shoot their event, tune their bike. Then a friend of theirs asked. Put those people in one contact list now, so the third and fourth do not get lost in a chat thread.

Your First Real Estimate

Quoting a number in a text message is how you end up underpaid. Write it as an estimate with line items and terms, send it, and let them accept it online. It takes ten minutes and it changes how the job goes.

A Link People Can Book

Put a booking link in your bio, your signature, your reply. People pick a time that works, you get a confirmation, and nobody has to negotiate a calendar over messages.

Get Paid Like a Business

An invoice with your name on it, paid online by card or bank transfer, with a record you can find next April. When you register the company, the history comes with you.

Built to Be Grown Into

Free Until It Is Real

The Free plan needs no card and does not expire. Basic is $9.95/mo when you want the full one-person toolkit, and the price never goes up on you. Nothing to cancel if the idea does not take.

No Migration Day, Ever

The contacts you add today are the CRM your team uses in three years. Upgrading a plan turns on apps; it never moves your data. And you can export it any time.

Someone to Ask

"How do I word this quote?" "What did I charge last time?" The AI assistant knows your records and answers from them. Every plan includes a monthly token cap.

Start before you feel ready.

Free plan, no card, no expiry. Basic from $9.95/mo when it is time.

Upgrade, downgrade or export whenever you like.
