Understanding Billing Constants
The billing constants represent your company's decisions about how source transactions and related billings are processed. The constants control how the system processes:
Billable costs.
Customer information.
Dates.
Invoices.
Journal entries.
Default markup percentage.
Multicurrency transactions.
Draft and final invoice numbering.
Revenue recognition on non-T and M (non-time and material) transactions (Contract Billing only).
Burdening transactions.
After you set up the constants, you should not change them. The system stores the constants in the Billing System Constants table (F48091).
