Click to enlargeThe business overview a solo operator opens every morning — revenue, pipeline, invoices, tasks and appointments in one view. 1 Before / After ### Leads Come In — You Capture Them Before EternalEngine: leads arrive by email, phone, website form and social DMs, and you track them in a spreadsheet when you remember. After: every lead lands in the ClientForge pipeline with the conversation on the record. You set follow-up reminders, see every open opportunity in one place, and stop losing the ones you forgot to reply to. Contact managementLead captureFollow-up reminders 2 Before / After ### Send Estimates & Win More Work Before: you build estimates in Word, email PDFs and wait; clients print, sign, scan and email them back — maybe. After: you build a branded estimate in minutes with your logo and terms, the client reviews and accepts it online, and its status moves from sent to viewed to accepted as they do. Estimate builderOnline acceptanceStatus tracking 3 Before / After ### Schedule & Coordinate Before: Google Calendar, a paper planner, or memory. Double bookings happen and appointments slip. After: jobs, meetings and deadlines share one calendar, recurring tasks are set once, and on Team a BookSlot booking page lets clients pick a slot themselves. SchedulingShared calendarBooking page 4 Before / After ### Get Paid Faster Before: you invoice from QuickBooks or Word, email it, and wait 30, 60, 90 days between awkward reminders. After: you invoice from the platform that already holds the client and the estimate, the client pays online by card, Apple Pay, Google Pay or bank transfer, and Stripe pays out to your bank on its standard schedule.

Free replaces the spreadsheet-CRM habit at no cost, and Basic at $9.95/mo still undercuts most single-purpose scheduling tools while adding invoicing, a CRM and AI. ## Why Small Businesses Choose EternalEngine ### One Bill, Not Five CRM, estimates, invoicing, scheduling, email and an AI assistant on one subscription instead of a spreadsheet plus three free-tier tools that don't talk to each other. ### Starts at $0 Free is one user, the full CRM, 5 invoices and 5 estimates a month, no card and no time limit. Basic at $9.95/mo removes the document limits when you outgrow it. ### An AI Assistant Included Every plan, including Free, includes Albedo AI assists for drafting emails, summarizing a client's history, or drafting an estimate description — not an add-on you have to unlock. ## How EternalEngine compares for small business See an honest, feature-by-feature comparison against the tools small business teams already know.
