SM-Mobile is an app to allow field service workers to keep track of all scheduled job appointments they have for the day (or week, or any other time period). The app gets data from the company server, and displays it on the mobile device. Then, the technician, or supervisor can easily see all of his/her jobs for the period. A finger-tap will reveal all details for the job. The field technician can also get a signature from the customer, take photos at the jobs site, receive payments, including credit card payments, from the customer and record the details in the app. SM-Mobile is designed to work in conjunction with Scheduling Manager, the multi-function scheduling, accounting and CRM software program designed for service businesses, from Thoughtful Systems. In SM-Mobile, the technician can also see maps for all jobs for the day, or for a single job. Technician can also record notes about each job, record payment details and indicate start and end time for each job. That Mobile data is then synchronized back to the company server, where it is incorporated into Scheduling Manager. SM-Mobile can be used by workers and management in a wide variety of field service businesses, including residential cleaning businesses, HVAC and electrical repair businesses, home health care businesses, liquid waste management, pest control, fire extinguisher management and other service businesses.

B4C — Before the Call is the readiness platform built for fire and EMS departments. It keeps the records that prove your department is ready — station hours, certifications, turnout gear, and apparatus — organized, verified, and ready the moment an inspector, board member, or grant office asks. B4C is an administrative platform, not a dispatch or response tool. It handles everything that happens before the call: the training, the credentials, the equipment, and the hours that keep your people and your apparatus ready to roll. VERIFIED STATION HOURS Log duty and standby hours with location verification, so the time that feeds your ISO rating, LOSAP awards, stipends, and grant reporting is accurate and defensible. With the optional geofencing add-on, station hours log automatically — members are checked in when they arrive at the station and out when they leave, no manual punches. CERTIFICATIONS THAT NEVER LAPSE QUIETLY Track every member's certifications and expiration dates, attach proof, and get ahead of what's expiring before it becomes a compliance gap. TURNOUT GEAR AND EQUIPMENT Assign gear to members, record serial numbers and condition, and track each item to its NFPA service life so nothing rides past its retirement date. APPARATUS CHECKS, MAINTENANCE, AND CAPITAL PLANNING Record rig checks, log maintenance and costs, and keep a full service history. Set a replacement year for apparatus and equipment and B4C projects the future cost and the savings plan to be ready for it. TRAINING AND ATTENDANCE Verified training sign-in closes the honor-system loophole, and attendance flows straight into your compliance numbers. FUNDRAISING, DONATIONS, AND SPONSORS Plan and run fundraisers end to end in Fundraiser HQ — turn a plan into action items and calendar dates, draft appeal and sponsor letters, and track sponsors and proceeds. Record gifts, manage funds toward goals, and see what your department has raised this year. STATION ASSISTANT Ask questions about your department's own uploaded SOPs and policies and get grounded answers, plus general fire and EMS guidance. REPORTS AND A WEEKLY READINESS DIGEST Board-ready reports whenever you need them, and an automatic weekly email digest that surfaces expiring certs, gear due for retirement, and overdue maintenance before anything slips. Everything lives in one shared system: quick actions and reminders on the phone, deep administrative work on the web — one record of truth for your whole department. B4C is a product of Big Bull Technologies. B4C is a records and readiness platform and is not used for emergency dispatch or response. Do not rely on it in an emergency.
