Having assisted many congregations in their stewardship efforts, I have seen a variety a ways to provide member financial statements.  The timing of the statements has varied, ranging from a monthly statement to just one statement at the end of the year.  I have also seen varied content and style, ranging from statements that look like utility bills, to statements that promote mission and ministry.

Of all the approaches I have seen, my preferred approach is a monthly mailing with two parts.  The first part contains a brief message from the pastor, staff member, or some other ministry leader expressing thanks, and sharing a story about how people's lives are being touched by the ministries of the church.  These stories remind members why their financial stewardship is important to God's ministry.  

The second part of the mailing is a financial update indicating the member's annual pledge and their giving year-to-date.    If the congregation is in the midst of a capital campaign, the member's campaign pledge and campaign giving to-date is included.  A "Thank You" should be part of this section.

A tear-off section can be provided whereby members can write in the amount of their next contribution.  They place the tear-off and bank check, inside an enclosed envelope and mail it to the church or drop it into the collection basket. 

The key is to take every opportunity to promote ways financial stewardship results in positive results for God's ministry and to take every opportunity to say "Thank You!"
