Why EternalEngine

## Built to replace the stack, not add to it

Three workflows that usually take three or four separate tools — and what they look like when everything lives in one system.

01

Tool consolidation

### Replace four subscriptions with one login

CRM, invoicing, project tracking, and scheduling usually means four tools, four bills, and data copied between all of them. Here they are one system — a deal flows to a project, a project to an invoice, without re-entering anything.

[See the apps→](https://eternalengineos.io/features)

02

Estimate to invoice

### One click from accepted estimate to sent invoice

Build the estimate in BidForge, get it accepted, and TitanLedger turns it into an invoice with the line items already in place. No copying between systems, no numbers drifting out of sync.

[See financial operations→](https://eternalengineos.io/features/financial-operations)

03

AI-ranked pipeline

### Chase the deals most likely to close

AI lead scoring ranks your pipeline by conversion signals instead of gut feel, so a small team spends its limited hours where they count. Scores update as activity happens.

[See lead scoring→](https://eternalengineos.io/features/crm/lead-scoring)

Free never expires and there is no card to start. Paid plans cancel in two clicks, and your data exports any time.[See a guided walkthrough →](https://eternalengineos.io/demo)

Answers

## Frequently asked questions

Everything you need to know about EternalEngine. Can't find what you're looking for? [Contact our team](https://eternalengineos.io/contact).

### What is EternalEngine?

EternalEngine is the operating system for service businesses. It combines CRM, scheduling, estimates, projects, invoicing, file storage, community forums, transactional email, and payments into one unified platform. Instead of stitching together a CRM, a project tool, an invoicing app, an email service, and a payment processor, you run everything from one dashboard with shared data and a single bill.

### Who is EternalEngine for?

Service businesses, agencies, contractors, consultancies, and any team that manages clients, projects, and invoices. Solo operators start on Free or Basic; small teams of three fit Team; growing teams of five fit Pro; established agencies with up to 15 seats and white-label needs land on Business.

### How does pricing work?

five self-serve plans, plus Enterprise (custom): Free ($0, 5 invoices and 5 estimates a month), Basic at $9.95/mo (1 user), Team at $49/mo (3 users), Pro at $99/mo (5 users, our most popular), and Business at $199/mo (15 users + white-label + SSO) — every paid plan starts with a 30-day free trial. Annual billing saves 20% on every plan. Pro adds eight apps to Team; Business adds operational features (white-label, SSO, forecasting, priority same-day email support) on top of Pro — not new apps. Prices shown do not include applicable tax.

### What does the built-in AI assistant do?

Every plan includes the AI assistant. It drafts emails, summarizes deals, scores leads, generates documents from templates, and answers natural-language questions about your data ("show me deals over $10K closing this quarter"). Each plan ships with a monthly token cap; if you need more, AI Credit Top-Ups stack on top — one-time purchase, no subscription, applied instantly.

### Can I try EternalEngine before committing?

Yes — request a demo from the homepage and our team will walk you through your specific use case. Once you sign up, you can change plans or cancel any time from account settings. There are no long-term contracts and no setup fees on any plan.

### Can I migrate from another CRM?

Yes. EternalEngine supports CSV import for contacts, deals, and companies. You can bring your existing data in minutes. For larger migrations or custom data shapes, our team can assist — request a demo or use the contact form.

### Can I cancel my subscription?

Yes — cancel, downgrade, or upgrade any time from your account settings. No long-term contracts, no cancellation fees. If you cancel, you keep access through the end of your current billing cycle and your data and configuration are preserved if you ever come back.

### Is my data secure?

Security is foundational, not an add-on. EternalEngine enforces database-level tenant isolation via Postgres row-level security, TLS 1.3 in transit, encrypted backups and secrets, role-based access control, and full audit trails for every action. Card data is handled by Stripe and never stored on our servers. We engineer against OWASP ASVS and NIST SP 800-218. Business adds SSO / SAML for enterprise identity. Your data is yours — we never sell or share it.

## Run your business from one place.

Five plans, seventeen launch apps, one dashboard. Set up in under 5 minutes — change tiers any time.
