Your vendor black book is the business. Treat it like one.

Couples do not hire you for your organizational skills, whatever they say in the consult. They hire you for your people. The florist who never misses, the photographer who calms a nervous groom, the caterer whose staff notices an empty water glass from across the room. Your roster is your product.

And yet most planners store this crown-jewel asset as a contacts list and a set of feelings. The feelings are usually right. But they do not scale, they cannot be defended to a couple pushing back on a recommendation, and they walk out the door with your memory.

For every vendor, across every wedding: how many times you have booked them, what they actually cost each time, and how often a shortlisting turned into a booking. Three numbers, kept automatically if your software is any good, and suddenly your instincts have receipts.

The typical-cost number alone changes conversations. When a couple asks "is this florist quote normal?", answering "you are within 8 percent of what my couples typically invest with her" is a different profession than answering "that sounds about right."

The Monday after every wedding, rate every vendor on the job while the details are alive: on time or not, over or under scope, how they handled the thing that went sideways, because something always does. A year later, when you are choosing between two caterers for a similar event, those notes are the whole decision.

Be honest in your own records. The black book only works if a three-star rating in it means something.

A roster is also defined by who gets cut. A vendor who is wonderful at their craft but late twice is a risk you price in or a name you retire. Sentimentality here gets paid for by a future couple on their only wedding day.

When you do recommend, recommend from data with warmth on top. The couple gets your taste, backed by your history. That combination is not something a venue's preferred-vendor PDF can compete with, and it is why your fee is worth it.
