Promotional products can be surprisingly effective in the world of private investigation. Discreetly branded items like pens, USB drives, or notepads can enhance credibility and professionalism during client meetings. These tools not only promote your investigative services but also serve practical roles in fieldwork. Just as every detail matters in an investigation, well-chosen promotional items reinforce your brand, build trust, and subtly keep your services top of mind for future referrals.
