# Salon booking day worksheet

Companion guide: https://www.overskill.com/learn/plan-a-salon-booking-day

Use this as an editable planning record. The filled example is fictional. Expected
starts are a calculation, not proof that a booking app has passed testing.

## 1. Set the scope

Business/location:
Date:
Business timezone:
Staff working hours:
Start grid (for example, every 15 minutes):
Must cleanup finish before a break or closing?
Can a staff member handle only one service at a time?
Shared rooms/equipment, processing time or assistant handoffs to model separately:

## 2. List services and eligibility

| Service | Customer minutes | Cleanup minutes | Occupied minutes | Eligible people |
| --- | --- | --- | --- | --- |
| Example cut | 30 | 15 | 45 | Ada, Mo |
| Example restyle | 60 | 15 | 75 | Ada |
| Example beard tidy | 15 | 0 | 15 | Mo |
| Your service | | | | |

Replace every example. Zero cleanup is an example input, not a recommendation.

## 3. Record unavailable periods

Filled sample: both people work 9:00 AM–1:00 PM; all times use the same business
timezone; starts are every 15 minutes; occupied time must fit within a free window.

| Person | From | Until free again | Reason |
| --- | --- | --- | --- |
| Ada | 9:00 AM | 9:45 AM | Existing cut, including cleanup |
| Ada | 11:00 AM | 11:30 AM | Break |
| Mo | 9:30 AM | 10:15 AM | Existing cut, including cleanup |
| Mo | Noon | 12:30 PM | Break |
| Your person | | | |

Your free windows after subtracting these periods:

## 4. Calculate expected starts

For each eligible person and service, keep a grid start only when the whole
occupied period fits in a free window. Equality at the boundary is allowed:
finishing at 11:00 fits before an 11:00 break; starting at 11:30 fits after it.

Filled original answer (times before noon are AM, times from noon are PM):

| Service | Person | Valid starts |
| --- | --- | --- |
| Cut | Ada | 9:45, 10:00, 10:15, 11:30, 11:45, noon, 12:15 |
| Cut | Mo | 10:15, 10:30, 10:45, 11:00, 11:15 |
| Restyle | Ada | 9:45, 11:30, 11:45 |
| Restyle | Mo | None: not eligible |
| Beard tidy | Ada | None: not eligible |
| Beard tidy | Mo | 9:00, 9:15, 10:15, 10:30, 10:45, 11:00, 11:15, 11:30, 11:45, 12:30, 12:45 |

These are alternative starts, not total sellable appointments. Recalculate after
any booking or schedule change. Any-staff availability is the union of eligible
people's starts; confirmation must assign and reserve one named person.

| Your service | Person | Expected starts | App's displayed starts | Differences |
| --- | --- | --- | --- | --- |
| | | | Unverified | |

## 5. Explain rejected starts

Filled example: Ada's 10:30 cut ends for the customer at 11:00 but occupies her
until 11:15. Her 11:00 break means that start is invalid.

| Requested service/person/start | Fits or fails? | Reason |
| --- | --- | --- |
| | | |

## 6. Change one input

Variation A: from the original sample, cancel Mo's 9:30 appointment and release
its block immediately. His cut starts become 9:00, 9:15, 9:30, 9:45, 10:00,
10:15, 10:30, 10:45, 11:00 and 11:15. No afternoon cut fits. He remains
ineligible for restyles.

Variation B: restore the original sample, then add 15 minutes of cleanup to the
beard tidy. Its 30-minute occupied period fits for Mo at 9:00, 10:15, 10:30,
10:45, 11:00, 11:15, 11:30 and 12:30. The old 9:15 and 12:45 starts fail,
as does 11:45 because cleanup runs into the noon break.
