As answered by people managing CellAlert and ShellNewHandler.
CellAlert's answer
Most deadline management tools require you to move data into a new system. CellAlert works with the spreadsheets and databases businesses already use. It automatically turns dates from Excel, LibreOffice and FileMaker into a centralized deadline platform with reminders, team visibility, history tracking and compliance documentation.
CellAlert's answer
CellAlert is designed for organizations that already manage information in spreadsheets. Instead of replacing existing processes, it adds deadline tracking, email reminders, audit trails, calendar integration and team collaboration on top of existing data sources. This makes implementation faster, simpler and significantly less expensive than traditional compliance or contract management systems.
CellAlert's answer
CellAlert is built for small and medium-sized businesses, quality management teams, compliance officers, operations departments, consultants and organizations that track contracts, certifications, audits, inspections, training records or other critical deadlines in spreadsheets or databases.
CellAlert's answer
CellAlert was created after seeing how many organizations still manage important deadlines in Excel files. Critical dates such as contract renewals, certifications, audits and inspections were often hidden across multiple spreadsheets and depended on individuals remembering to check them. CellAlert was built to turn existing business data into a shared, automated reminder system without requiring companies to replace the tools they already use.
