Is there a limit to how many song/service sheets we can copy under our license?

There is no limit to the number of copies you can make under your Church Copyright License® provided they are solely intended for congregational use. The only exception is for CD or DVD recordings of a service made for limited distribution (e.g. for the housebound). The number of CD/DVD copies must not exceed 15% of your license size category. For example, for Category A (25-99) you may make a maximum of 15 copies per service.
