It's not just the way to name a price for the project but to write down in detail what the client has to pay.
Place each performed service and amount of time worked. For example, if specialists create an app, write down every step and state the number of worked hours: marketing analysis — 10 hours, UX/UI design — 20 hours, HTML — 5 hours, etc. Let the client know why the price is like that.With a consistent pattern, the managers are able to create the same invoice but for different clients. That's how one can optimize it, understand what to add or what to delete, and get data that will help it grow in the future.
Keep all invoices in one secure place and check statuses when needed. Wobbly is a great tool as it allows one to manage time tracking and invoicing in one-time tracking and billing software.
