Digital tools are most useful when they address a clear need and fit the user's connectivity, skills, budget and working routine.
Begin with the task rather than the app: do you need to track inventory, record sales, coordinate workers or communicate with buyers? Compare the cost, offline access, data export options, support and privacy implications. Test a simple workflow before moving important records. A paper register or spreadsheet can be appropriate in some situations; digital adoption is not automatically an improvement unless it makes the work more reliable or decisions more informed.
