I'm writing a companion document to a spreadsheet my company provides to clients. The spreadsheet consists of columns that correlate to the database, and, therefore, cannot be changed, added to, or otherwise updated.
I want to explain—in a non-techie way—that the programming itself is, well, plug-and-play. We install it and the data/functionality is what it is.
Is there a single word or simple phrase that accomplishes this? I'm worried the phrase "plug-and-play" might be a little too specific/rare for quite a bit of our clientele.
Here's the opening sentence, if it helps at all:
The products module is a «something» e-commerce solution.
There seems to be a bit of confusion. Here's a little more context: We provide a product upload via a pre-set spreadsheet. The spreadsheet itself does not update.
