Bookipi Invoice - Feature request

Would be nice if we have an option to change the invoice templates or atleast the primary colors which can match the particular brand or company.

Let the customer pay half the invoice at the beginning of the job and then finish payment at the end, so the ability to make part payments with each invoice

Ability to have more than one user on a main Bookipi account. Have admin access options for staff.

The ability to upload an existing database of customers would be a huge timesaver instead of having to re-enter all the data.

Sometimes it can be awkward to remind certain clients that they haven't yet paid you. An option to automatically (or with one click) send a reminder to clients with overdue invoices would be great to help with that.

Currently pictures are small, not resizable, and low resolution. I would like photos to be larger, possibly even adjustable in size; or attachable as separate files. Being able to attach other files to the invoice, such as PDFs, Docs, Sheets, etc wo

The paid invoice can automatically be converted into a payment receipt by only converting the header into 'invoice paid' or 'payment receipt'. this is in reference to the pdf extract

It is rather tedious and time consuming to add items one by one or to create them when making a new invoice or estimate and saving to the library. It would be extremely helpful to make it possible to import a .csv file with the entire list at once.

All data may store to google drive, so that it can be easily locate from anywhere from any drive in exel format

Some products we sell are sold by weight, others by slice, others by box. All products should have a "units" field so these can show on the invoice for customers.
