The short answer
To deduct a business meal, recording who was there is not optional. The substantiation rules ask for the amount, date, place, business purpose, and the business relationship of the people at the meal. The attendee record, together with the purpose, is what tells the IRS this was a business meal rather than dinner with friends.
Who counts as an attendee
An attendee is anyone whose presence ties to the business reason for the meal: a client or prospect, a vendor or partner, or an employee at a working meal. You note their name and their business relationship to you, for example client, supplier, or team member. It is the relationship plus the purpose that carries the deduction, not just the fact that a meal happened.
Big groups vs small groups
For a small meal, list the individual names. For a large group, you do not need every name; a reasonable description of the group is accepted, such as the attendees of a department lunch or a client event. The point is that a reviewer can see who benefited from the meal and why, at the level of detail the situation calls for.
Recording it without the hassle
The hard part is not the rule, it is remembering to write it down. Do it at the time, on the receipt or in your expense app, while you still know who was there. Keep the itemized receipt too; see are business meals tax deductible for the 50% limit and IRS receipt requirements for the substantiation basics.
The faster way: let Mylo keep the proof automatically
This is where Mylo quietly does the heavy lifting. It works in the background to capture every receipt from your inbox and the stores you shop at, matches each one to the card charge that paid for it, and files it as a categorized expense, so when you claim a business meal with attendees the proof is already there. No new card and no manual entry: Mylo works on top of the Visa, Mastercard, or Amex you already use, and syncs clean, categorized expenses to QuickBooks. Free for individuals on iOS, Android, and the web; teams are $9/user/mo (30-day free trial).

Frequently asked questions
Who counts as a business meal attendee?
Anyone whose presence relates to the business reason for the meal: a client, prospect, vendor, partner, or employee. You record their name (or a group description) and their business relationship to you.
Do I have to list every name for a big group?
No. For a large group, a reasonable description of the class of attendees is acceptable, for example a team lunch for the sales department. For a small meal, list the individual names.
Why does the IRS care who attended?
Attendees and the business relationship are part of the substantiation rules for meals. They are what distinguish a deductible business meal from a personal one, so the record supports the deduction if it is ever questioned.
How does Mylo handle attendees?
Mylo can attach who was present and the business purpose to the meal receipt, so the context stays with the expense instead of living in your memory.
