C62 or H87?
Both are used for quantities. C62 is a plain count with no unit, H87 a single piece. Both are allowed. Unless the recipient specifies one, using either consistently is enough.
A common mistake
Text such as "pcs", "Stk" or "h" instead of a code triggers rule BR-CL-23, and the invoice is invalid.
