Office Lunch Headcount and Service Window Planning (Bengaluru)
AI Overview
For a free catered office lunch, plan for 90% of on-site headcount; for optional or paid meals, 60–70%. One serving line clears about 100 guests every 25–30 minutes, so a 45-minute window for 400 guests needs at least four parallel lines.
Key takeaways
- Free lunch: 90% of on-site staff. Paid or optional: 60–70%.
- Conference attendance drops 10–15% after the morning session — plan lunch on the post-tea count.
- One serving line = ~100 guests per 25–30 minutes.
- Always brief dietary needs as counts, not as 'a few Jain guests'.
- Confirm the final figure 48 hours out; corporate counts move later than wedding counts.
Corporate catering is a logistics job with food attached. The menu matters, but the two things that decide whether the event is judged a success are whether everyone ate and whether they were back in the hall on time. Both are arithmetic.
Forecasting attendance
| Event type | Apply to | Factor |
|---|---|---|
| Free lunch, staff on site | On-site headcount | 90% |
| Free lunch, hybrid office | Badged-in count for that weekday | 85% |
| Paid or optional meal | Registered count | 60–70% |
| Conference lunch | Post-morning-session count | 85–90% |
| Annual day with families | RSVP heads | 95% + 10% walk-ins |
| Evening networking with snacks | Registered count | 70–75% |
Sizing the service window
A corporate lunch window is fixed by the agenda, not by the kitchen. Work backwards from it.
Step 1
Fix the window
The real window is the agenda break minus ten minutes for walking and washing hands.
Step 2
Divide guests by 100
Each single-sided line clears about 100 guests in 25–30 minutes.
Step 3
Divide again by window blocks
A 45-minute window is 1.5 blocks of 30 minutes, so each line handles ~150 guests.
Step 4
Round up and add one
Never run at exactly capacity — one slow item stalls the whole line.
| Guests | Window | Serving lines needed |
|---|---|---|
| 150 | 45 min | 2 single-sided |
| 400 | 45 min | 4 single-sided or 2 double-sided |
| 800 | 60 min | 6 single-sided plus 2 counters |
| 1,500 | 90 min | 10 lines, staggered by floor or department |
Menus that survive two hours in a chafing dish
- Choose gravies over dry items — dry palya dries out within forty minutes under heat.
- Avoid dosa and poori on a buffet line; they hold badly. Put them on a live counter or leave them out.
- Rice, biryani, dal and paneer gravies hold best across a long window.
- Keep raita and salads on ice, refreshed every 30 minutes.
- One item too spicy for a mixed office is a wasted item. Keep chilli moderate and offer chilli separately.

Frequently asked questions
- How do you calculate headcount for corporate catering?
- Apply an attendance factor to the nominal count: 90% for a free on-site lunch, 85–90% for a conference lunch based on the post-morning-session count, and 60–70% for optional or paid meals.
- How many serving lines are needed for 400 people in 45 minutes?
- At least four single-sided lines, or two double-sided lines. Each line clears roughly 100 guests every 25–30 minutes.
- What food works best for office catering?
- Gravies, rice dishes, biryani, dal and paneer preparations hold well across a two-hour service. Dry vegetable dishes, dosa and poori deteriorate quickly on a buffet line.
