Nope! That is entirely up to you.
During profile setup you have the option to publicly list prices for services, or turn on the 'Do not show price' option.
This information can be changed or updated at any time by visiting your 'Profile' and scrolling to the 'My Services' section.
Here you can add or remove services from your profile, adjust pricing, and edit pricing visibility.
You are able to adjust the price all the way up until closing out the job, so having a base price listed and communicating directly with the customer after receiving equipment details is a great way to get booked ASAP.
