Scheduling

Schedule service calls and track work

Create appointments for service calls and capture job details on-site. Set job site addresses, attach photos, add notes, and track from scheduled to completed. Simple scheduling keeps customer appointments and job history visible without complex systems—just essentials for job management.

Estimates

Send estimates that look sharp and land jobs

Build and send clean, detailed estimates from your phone in just a few taps. Add parts, labor, and service notes so clients know exactly what to expect.

Price Book

Save time with consistent pricing

Store your commonly used services, materials, and rates. Build electrical estimates faster by selecting saved items instead of retyping prices. Price Book ensures accurate, consistent quotes across all jobs—no searching old invoices for pricing.

Invoices

Send clean, professional invoices in seconds

Turn an estimate into an invoice with a single tap. Add your logo, payment terms, and job notes and keep everything sorted by client or job.

CRM

Keep customer records organized

Store customer information in client profiles instead of scattered notes. Every customers record includes contact details, complete job history with photos and status updates, job information, and communication logs in one place. Simple customer management for your business.

Mobile Access

Work offline, just like you do on-site

Tofu works even without signals. Create invoices from rooftops, crawl spaces, or in the truck. Everything saves and syncs once you're back online.
