AUTO555 vs Merlin AI: Which Is Better in 2026?

AUTO555 is a browser-based CRM and ERP for vehicle-rental businesses. It brings the fleet, bookings, customers, rental documents and financial records into one workspace. The interface is in Russian. It is designed for teams that currently distribute rental information across spreadsheets, messages and paper documents and want to follow the same booking through several stages of work.

The fleet section keeps vehicle information together. The booking calendar helps staff see vehicle availability and review reservations. Customer records connect a renter with the relevant rental history. Document tools support rental contracts and receipts, while operational records include deposits, vehicle inspections, photographs, maintenance and fines. These sections help a rental company check the information behind a booking rather than relying on a separate conversation to explain it.

A public, read-only demo is available at https://app.auto555.ru/demo. The demo contains fictional vehicles, customers and bookings. It is useful for inspecting the layout and navigation before creating a working account. The screenshots attached to this listing show the real product and its fictional demo records. They are not customer case studies or evidence of financial results.

The Standard plan is permanently free for one user and up to five vehicles. It includes core booking, client, document and reporting tools. Premium costs 2,990 RUB for a one-month subscription and supports up to three users and twenty vehicles. Corporate costs 10,990 RUB for one month, with up to fifty users and an unlimited number of vehicles. Longer billing periods have separate discounts shown on the official site.

A public website for the rental business is included with paid plans. On the free plan, the public storefront is listed as a separate one-time purchase of 39,990 RUB. This matters when comparing the cost of the internal CRM with the cost of a customer-facing booking site.

AUTO555 provides REST API and webhook capabilities for integrations. Specific connectors, including 1C, electronic document exchange, traffic-fine services and external booking marketplaces, should be checked individually: connectors marked as being developed are not presented here as finished integrations.

AUTO555 is developed by Levitsky Concept. Product questions can be sent to auto555@levitsky-c.ru.

What problem it solves

Rental teams need to reconcile vehicle availability, reservations, client records, documents and deposits when these are kept in separate spreadsheets and conversations. AUTO555 groups these records around the rental workflow.

MerlinAI is an AI-powered ERP built exclusively for the construction industry. It unifies estimating, procurement, project management, materials, shop floor operations, and financials into one agentic platform. Three product lines serve the full ecosystem: Merlin EOS runs production operations for contractors, Merlin PI coordinates supply chains for developers, and Merlin Merchant connects suppliers to live construction projects.
Merlin AI brings project management, estimating, materials tracking, job costing, finance, scheduling, and CRM together into a single platform, so construction teams aren't stitching together separate tools for each function. Its AI-powered execution intelligence surfaces margin erosion, schedule slippage, and cost risks early, connecting real-time job costing directly to scheduling and materials data so budget and timeline never drift apart unnoticed. Built specifically for construction workflows rather than adapted from generic project management software, it serves general contractors, real estate developers, trade contractors, and modular/manufactured builders in one unified system.

Who is the software for?
General contractors, real estate developers, trade contractors, and modular/manufactured builders construction businesses that need to manage estimating, job costing, scheduling, and finance without juggling disconnected spreadsheets or point solutions.

What does it do for them?
Merlin AI gives construction teams one system to plan, cost, schedule, and execute projects replacing manual tracking and fragmented software with AI-driven visibility into margins, timelines, and materials, so teams catch problems early instead of after a project's already over budget or behind schedule.

What problem it solves
Construction companies run 8–17 disconnected tools separate software for estimating, procurement, scheduling, materials, finance, and CRM none of which talk to each other in real time. Teams spend more time moving data between systems than running projects, and problems only surface after they've already caused delays or cost overruns. MerlinAI replaces that fragmented stack with one AI-powered platform that coordinates everything in real time. The pain is felt by contractors, property developers, and building material suppliers.

Alternatives & competitors
MerlinAI is an alternative to Procore, Buildertrend, and Autodesk Construction Cloud but unlike those tools, which report on work after it happens, MerlinAI's agentic AI orchestrates projects in real time. It also replaces legacy construction ERPs like Sage 300 and Viewpoint Vista, which are expensive, slow to implement, and built on decades-old technology. MerlinAI is the only option built AI-native and exclusively for construction.
