Two fields cover the practical side of a booking: Equipment is what you bring, Requisites are what you need from the client or venue.
Requisites
In the Terms step of the proposal builder, select Select next to Requisites. There are thirteen:
Meal/Snacks · Electricity · Water/Softdrinks · Parking · Lighting · Microphone/PA System · Technical Support · Event Schedule · Storage Room · WiFi/Internet · Stage/Platform · Security Assistance · Marketing Collateral
Use My Default fills in the ones you set on your profile.
Choose them per booking
Your defaults are a starting point, not an answer. A four-hour bar set doesn't need a meal. An eight-hour wedding in a field needs power, parking, and probably storage.
Requisites you list are things the client agrees to provide. Listing thirteen every time trains clients to skim them, which defeats the point.
The ones that actually cause problems
Electricity. Obvious indoors, not obvious in a marquee or a garden. If you need a specific supply, say so here and again in the conversation.
Parking. Where you'll be carrying heavy kit a long way otherwise. Worth being specific about needing it close, not just present.
Stage/Platform and Storage Room. Easy for a venue to arrange with notice, impossible on the day.
Event Schedule. Getting the running order in advance is the difference between a smooth night and improvising around speeches you didn't know about.
Equipment
A free-text field in the Basic step describing what you're bringing. Use My Default pulls in the text you saved under Manage Defaults.
Be specific enough that the client can tell whether they need to hire anything else. "Full PA suitable for 150 guests, two speakers on stands, subwoofer, wireless microphone, and basic dance floor lighting" answers the question. "Professional DJ equipment" doesn't.
Mention what you're not bringing if it's commonly assumed — uplighting, a second setup for a ceremony in another room, a microphone for speeches.
Why this saves you money
Every unlisted assumption is a conversation on the day, and on the day you're the one who has to solve it. A client who agreed in writing to provide parking and a power supply is a client who arranged them.
Documents
For anything you want formally agreed rather than stated, use a document. The Equipment & Tech Policy and Parking & Venue Access templates cover exactly this ground. See The 8 Document Templates, and What Each Covers.
