Any data that appears on any file type other than .csv would have to be converted to .csv first. That is not an easy task to do automatically. My company has PowerPDF Advanced which is a very expensive PDF software that is supposed to be able to convert PDF to Excel or Word using OCR. In my opinion, it does a lousy job. The OCR recognition is so bad that I spend more time "fixing" all of the mistakes in the Excel sheet than it would have taken me to enter the data into a brand new excel sheet in the first place.
And you would have to edit the resulting converted file anyways because there are required headings that you must use in your .csv data file in order to map correctly to the Quickbooks fields. They must be exact or the import will fail.
Is there any reason you can't get the file that your client used to make the PDF from? Normally, PDF's are always created in some other native software first and only converted to PDF for ease of transport to others. What application did your client use to create the PDF? Could they use that application and create an excel file instead? That might be a good place to start.
If that is not an option then I would suggest you just make your own excel sheet for data within a time frame and type the data you see on the PDF into the sheet, save it as a .csv, and then do the import into QBO. When you go to do the import, there are is a good "import guide" and a preview of what your headings need to be to match the fields in QBO. You would have to create separate .csv files for each type of data that you want to import. i.e. Customers, Suppliers, Chart of Accounts, Products & Services, Invoices and Bills.
There is also a good third party app I've had great success with in the past which imports all of your transactions into QB with ease. But the starting point is still an excel spreadsheet. The reason I like this one is because it is a one-time fee and not a monthly subscription. You buy it, you own it. Here's a link to their site:

There's also another one QB recommends right inside the QBO app - https://c15.qbo.intuit.com/app/qboAppCard?shortName=excel%20transactions
This does the same thing as the one above, but the starting point is still an excel spreadsheet. The difference between this one and the one above is that this one requires a monthly subscription fee.
Best of luck to you!
