Combining signed PDFs

Hi,

We have just started using Acrobat's fill and sign functionality in our organisation.

The process for creating orders means a purchase order form is completed and usually requires two or three signatures. When that's done, a formal purchase order can be raised. This then needs to be saved in the same file as the original purchase order form, but this can't be done because the file is finalised due to being signed. So the user currently takes a screen shot of the signed purchase order form and adds that to the same file as the formal purchase order. However, within the same file, an invoice and delivery note (if applicable), also signed, have to be added; the finance software allows only one file to be uploaded containing all of the above to be linked to one purchase order number). As each have to be signed, this means the user has to get PDFs sent out for signing and then has to screen shot them to add them all to the same PDF document for saving in the finance software.

An alternative we've considered is the use of a PDF Portfolio, but it seems these can't be viewed within a web browser, as as they're heavily dependent upon viewing these files from SharePoint, it makes things more complicated for them.

Does anyone have any solutions to how the above process can work better? Will purchasing licenses for the full Fill and Sign do what we need it to do?

Many thanks in advance for any words of wisdom!
