Intresting question. I'm gonna have to say 27.15. Here's why.
I looked at 20 invoices since seeing this question, and counted and wrote down the number for each. They were
20
19
20
26
22
16
29
16
35
43
25
36
21
24
27
20
26
51
18
+ 49
543
total fields/total number of invoices (20)= 27.15 = avg. # flds in invs for 1-line item purchases
Most of these had 3 addresses, bill-to, ship-to, remittance, and each address has 4+ fields, address street, city, state, zip. So if you add those 12 to the invoice number, product and price, i guess there are a min of 15 fields in the avg invoice.
