You do not sell online, but the customer has to see the range, the specifications and download a data sheet.
All of them come from the catalogue being a file rather than part of the site.
They type a model code and a power rating into Google. Your catalogue is a PDF whose contents the search engine does not index. They end up at a competitor.
In LessCMS: every product is a separate page with the specifications in the content — the search engine reads them just like text.
The PDF has to be fixed, regenerated and swapped on the site. For a month the sales team keeps sending the old version.
In LessCMS: you change the value in a field. The product page and the downloadable file point at one source.
You send an email with an attachment, because there is no way to download the document from the site.
In LessCMS: the data sheet sits on the product, and the enquiry form is on the same page.
Products are split by series and by application. Filtering works on the same fields that describe the product.
How many fields is up to you. Technical catalogues often run to a dozen or more, and that is not a problem.
Take a data sheet and copy the headings off it. That is a ready-made set of fields.
The rest is the same form repeated — and it can be split between several people.
Data sheets and manuals are uploaded once; after that you only swap versions.
