Working with clients

Hello Dear Community !
I have an important questing about a dazzling situation I have while working with a client. The circumstances are like this :
If I am on a lite account plan, my personal one, I start a project - an e-commerce store for my client, I have build the entire landing page, but now, I want to move to an about and contact page, anyway or how, I need to add more pages than the free plan (site plan) offers, but I have not yet transferred the project to my client for them to pay hosting, how do I manage to continue building ? This is however without the option to set up client billing - as it is not supported in my country. Do I tell my client to open a webflow account, set up hosting on an empty project and then share passwords with them ?
