How do I work out how many cards to keep in stock?

Good quantity planning starts with data, not a guess. Track how many cards you actually hand out in a typical month, then order against that real rate instead of a round number that feels safe.

• Order for 6 to 9 months of your measured hand-out rate.
• Set a reorder trigger when you are down to about 50 cards.
• Cap any single order at roughly 12 months of supply so designs and details stay current.

This keeps per-card costs low through bulk pricing while protecting you from printing a huge run and then changing your phone number, title, or branding halfway through the stack.
