BBB A+ Rating
Cornerstone Services, Inc. holds an A+ rating with the Better Business Bureau — the highest rating the BBB issues. We have maintained continuous BBB accreditation since 1998 with no unresolved complaints. The A+ rating reflects our commitment to transparent pricing, responsive service, and ethical business practices across every direct mail and printing project we handle.
BBB accreditation is not automatic — businesses must meet the BBB's Standards for Trust, which include commitment to making a good faith effort to resolve consumer complaints, honesty in advertising, and transparency in business dealings. Our 27-year track record with the BBB speaks directly to how we operate.
