Is there a single word (or a short phrase) for "Total amount of all purchases"?
Example. List of purchases a company has made from us:
Total amount of purchases here would be 1430 + 150 + 2050 = 3630. In this context, I can name it simply "Total" since the reader has seen the table and knows what I'm about. But how would these 3630 be named from any context? Say, we're talking about a company and I tell you "That company's valuable to us since its ... is 3630"?
