Billing Tiers and Multipliers make it easy to customize your staff’s billing rates by client. The Billing Tiers are designed for firms where the large majority of client billing rates fall into one of three levels (Standard, Tier 1, or Tier 2). Staff may have different rates for each tier and work code, but you cannot add additional tiers beyond the three described above. However, there are no restrictions on the number of Billing Multipliers you can assign. Multipliers are client-specific and staff billing rates vary for the assigned client by multiplying their standard rate by a chosen percentage.
