Tick
Tick is a reporting solution to set budgets and time for your projects. With Tick, you can enter a timeframe for each task and budget and update it in real-time. This way, you can create time reports and collect data about the hours you have recorded for the week, month, or custom periods.
You can easily combine forms.app and Tick to create a customer profile on your forms. Then you can report how much time you spend on each customer and adjust your budget by using the reporting option.
