Hi Samuel

No. Version 9.3A of Invoices is the first module to allow for calculated fields on a spec:

(from the Release notes)
Added calculated numeric fields on invoices using formulas in the Specification Designer to do math (add, subtract, multiply, divide) on specification codes and constants. Added new Formulas, Numeric section to Specification Designer with new codes: X001..X005 Calculated Amount 1..5

But no module has if/then/else functionality.

Someone will certainly chime in and say that this can be done using PrintBoss.
