EstimateFlow is a cloud-based service for installation and maintenance companies working with low-voltage systems. Designed for teams in video surveillance, access control, fire alarms, intercoms, and related fields, it brings estimates, projects, engineers, documents, equipment, payments, and service history together in one workspace. Users can build estimates from a catalog of more than 2,000 items, create branded PDF documents, and turn approved estimates into project records.

The platform supports scheduling engineer visits, recording work and photos from a phone, tracking installed equipment, managing documents and finances, and planning routine maintenance. QR-based project passports provide quick access to site information and service history. EstimateFlow runs in a browser on computers, tablets, and phones, and complements rather than replaces accounting or inventory systems; integrations, including with Business.

Ru, are available as connected. A free plan includes up to two new estimates per month and two active projects, while the Pro plan removes these limits and adds full project, team, and maintenance workflows
