There needs to be consistency between all of your developers' timesheets, so you should get them all to adhere to the following:
✅ Figure: Good example - Inform accurately how much time you spent for each client
Record all the work you do for a client, even if it is to be written off
If you are working with another employee, ensure your times are consistent, in both time and category
If you are providing telephone support, count your time in 15 minute blocks
If you work for a client 4 times in a day for 15 minutes each, feel free to enter one timesheet for 1 hour, listing the 4 things you did. The extra information adds no value and only serves to clutter up invoices
