Treatment room turnover

The time and steps required to clean, restock and reset a treatment room between clients so the next appointment starts on schedule. It directly limits how many treatments a spa can sell per day.

Related: Treatment utilization rate, Standard operating procedure (SOP)
Treatment utilization rate

The percentage of available treatment hours that are actually booked and delivered. Calculated by dividing completed treatment hours by total bookable hours, it shows how well the schedule converts capacity into revenue.

Related: Treatment room turnover, Gross operating profit (GOP)
Standard operating procedure (SOP)

A written, step-by-step instruction for how a routine task must be performed, such as room setup or till closing. It standardizes quality and safety and makes training and auditing consistent across staff.

Related: Onboarding, Competency matrix
Par level

The minimum quantity of a product or supply that should be in stock before reordering. Par levels prevent both running out during busy periods and tying up cash in excess inventory.

Related: Standard operating procedure (SOP)
Gross operating profit (GOP)

A spa's revenue minus its departmental and overhead operating expenses, before interest, tax, depreciation and rent. Owners use it to judge whether the operation is profitable at the level managers control.

Related: Treatment utilization rate
Client intake form

A questionnaire completed before a first treatment that records health conditions, medications, allergies, pregnancy and injuries. The therapist uses it to identify contraindications and adapt the service safely.

Related: Contraindication, Client preference record
Service recovery

The planned response when a guest experiences a failure such as a late start, wrong room or discomfort. Effective recovery acknowledges the problem quickly, fixes it and records the cause to prevent repetition.

Related: Net Promoter Score (NPS), Client touchpoint
Client touchpoint

Any point at which a guest interacts with the spa, including booking calls, reception, the treatment itself, payment and follow-up messages. Each touchpoint shapes the overall impression and should be designed deliberately.

Related: Service recovery, Client preference record
Net Promoter Score (NPS)

A loyalty measure based on asking guests how likely they are to recommend the spa on a 0 to 10 scale. Scores of 9 to 10 are promoters, 7 to 8 passives and 0 to 6 detractors; the score is promoters minus detractors.

Related: Service recovery, Customer relationship management (CRM)
Client preference record

A confidential note in the booking system storing a guest's preferred therapist, pressure, products, allergies and past reactions. It lets returning guests receive consistent, personalized care without repeating information.

Related: Client intake form, Customer relationship management (CRM)
Contraindication

A condition, medication or circumstance that makes a treatment unsafe or requires it to be modified, delayed or refused. Examples include fever, open wounds, recent surgery and pregnancy for certain modalities.

Related: Client intake form, Patch test
Effleurage

A massage stroke using smooth, gliding movements of the palms and fingers, usually in the direction of blood flow. It is used to apply oil, warm tissue and begin or close a massage sequence.

Related: Petrissage, Draping
Petrissage

A group of massage manipulations that lift, knead, squeeze and roll soft tissue. Petrissage works deeper than gliding strokes and is used to release tension in muscle bellies, always within the client's comfort.

Related: Effleurage, Pressure scale
Draping

The use of towels or sheets to cover a client so that only the area being treated is exposed. Correct draping protects privacy and warmth and is a basic professional and legal requirement.

Related: Effleurage, Contraindication
Pressure scale

A simple agreed rating, often 1 to 10, that lets the therapist check how firm a massage feels to the client. It keeps pressure within comfort and avoids injury from too-light or too-heavy work.

Related: Petrissage, Client preference record
Essential oil

A concentrated, volatile aromatic extract obtained from plant material such as flowers, leaves or peel. Essential oils are never applied undiluted to skin; they are blended into a carrier oil at a safe percentage.

Related: Carrier oil, Patch test
Carrier oil

A plant-derived base oil, such as grapeseed or sweet almond, used to dilute essential oils and lubricate the skin during massage. It determines texture, absorption and how much essential oil is delivered.

Related: Essential oil, Patch test
Patch test

A small amount of product applied to a discreet area of skin, usually 24 to 48 hours before a full treatment, to check for an allergic reaction. A positive result means the product must not be used.

Related: Essential oil, Contraindication
Period after opening (PAO)

The period after opening during which a cosmetic product remains safe to use, shown by an open-jar symbol with a number of months. It differs from the unopened shelf life printed on the pack.

Related: Emulsion, Cross-contamination
Emulsion

A mixture of two liquids that do not normally combine, such as oil and water, held together by an emulsifier. Creams and lotions are emulsions, and their stability affects texture, shelf life and performance.

Related: Period after opening (PAO)
Cross-contamination

The transfer of microorganisms or product residue from one person, surface or container to another. In spas it is prevented by hand hygiene, clean linen, single-use items and never dipping into shared pots.

Related: Disinfection, Single-use item
Disinfection

A process that reduces the number of harmful microorganisms on a surface or tool, but does not necessarily destroy bacterial spores. It is the standard level of care for benches, bowls, brushes and shared equipment.

Related: Sterilization, Cross-contamination
Sterilization

A process that destroys all microorganisms, including spores, on an item. In spas it is reserved for reusable tools that penetrate or contact broken skin, such as metal extraction tools.

Related: Disinfection, Single-use item
Safety data sheet (SDS)

A standardized document supplied with a chemical product that lists its hazards, safe handling, first aid and spill response. Staff must be able to locate the SDS for every chemical used in the spa.

Related: Cross-contamination
Single-use item

A product or tool designed to be used once and then discarded, such as a disposable spatula, gloves or nail file. Using single-use items removes the need to disinfect and lowers cross-contamination risk.

Related: Cross-contamination, Disinfection
Upselling

Suggesting a higher-value version of the service the guest has already chosen, such as a longer duration or a premium product line. It should follow an identified need, not pressure.

Related: Cross-selling, Average transaction value (ATV)
Cross-selling

Recommending a complementary product or service that adds value to the current purchase, such as a home-care oil after a massage. It increases revenue per guest and supports treatment results.

Related: Upselling, Retail attachment rate
Retail attachment rate

Retail sales divided by treatment revenue, usually expressed as a percentage. It shows how often therapists turn treatment advice into take-home product sales and is a common spa performance target.

Related: Cross-selling, Average transaction value (ATV)
Average transaction value (ATV)

The average amount a guest spends per transaction, calculated by dividing total sales by the number of transactions. Spas track it alongside attachment rate to see whether selling and pricing are working.

Related: Upselling, Retail attachment rate
Treatment series

A prepaid or discounted set of several sessions of the same or similar treatment, sold to support a course of results. It improves client retention but must be recorded as unearned revenue until delivered.

Related: Customer lifetime value (CLV), Cross-selling
Target market

The specific group of guests a spa chooses to serve and market to, defined by needs, location, spending and lifestyle. A clear target market guides pricing, service design, staffing and promotion.

Related: Positioning
Customer lifetime value (CLV)

The total profit a guest is expected to generate over the whole relationship with the spa. It justifies spending on retention, loyalty programs and service quality rather than only on acquiring new clients.

Related: Customer relationship management (CRM), Treatment series
Customer relationship management (CRM)

A system that stores guest contact details, preferences, bookings, purchases and communication history. A well-used CRM supports personalized service, targeted marketing and follow-up after visits.

Related: Client preference record, Customer lifetime value (CLV)
Positioning

The distinct place a spa holds in the mind of its target guest relative to competitors, built from price, setting, expertise and atmosphere. Consistent positioning makes marketing messages and service standards easier to align.

Related: Target market
Competency matrix

A chart listing each role's required skills and the assessed level of every staff member against them. It identifies training gaps and supports safe scheduling of treatments to qualified therapists.

Related: Onboarding, Performance appraisal
Onboarding

The structured first weeks of a new employee's experience, covering orientation, policies, practical training and buddy shifts. Good onboarding reduces early turnover and ensures service and safety standards are met from day one.

Related: Standard operating procedure (SOP), Competency matrix
Staff turnover rate

The percentage of employees who leave over a period, usually calculated annually. High turnover raises recruitment and training costs and signals problems with pay, scheduling, management or career progression.

Related: Onboarding, Performance appraisal
Performance appraisal

A scheduled review in which a manager and employee discuss results, behaviors, development needs and goals. In spas it typically combines treatment quality, retail results, attendance and client feedback.
