One Place for Every Client's Details: Record Keeping for Salons, Trades and Practices

A client record kept in one place lets anyone at the business greet a returning customer as if they remembered them, and it keeps the business ready for the IRS, for privacy rules and for staff turnover.

At a glance

  • A client record is one entry per customer, kept in one system, that holds contact details, service history, preferences and the paperwork the business is required to keep, so the business remembers what a single employee might forget.
  • Research in the Journal of Consumer Research found that people treat being remembered as a compliment and become more willing to buy from the person who remembered them, which makes the record a customer experience tool, not only a filing system.
  • The IRS generally asks businesses to keep records for three years, employment tax records for at least four years and some records for six or seven, so the record system also needs a retention rule.
  • One template per trade, filled in at the end of every visit, is usually enough to start.

Part 1 | The business needs a memory that does not walk out the door

A regular at a barbershop expects the barber to remember the guard number, a homeowner expects the HVAC company to know the age of the furnace, and a patient expects the front desk to know which insurance they changed to last spring. In many small businesses those details live in one person's head, a paper card, a text thread and a booking app at the same time, and when that person is out sick or leaves, the customer is suddenly a stranger.

The owner's inner voice often says We know our customers; we don't need a system for that. It is true for the owner, though not for the newest employee on a Saturday, and research in the Journal of Consumer Research found that having one's name remembered works as a compliment that makes people more willing to buy, which means every forgotten detail costs a small amount of goodwill. In PwC's 2018 survey of more than 15,000 consumers in 12 countries, knowledgeable employees and friendly service ranked among the most valued parts of a customer experience, and a good record is how an employee who has never met the customer becomes knowledgeable in 30 seconds.

Part 2 | What to record, in each trade's own terms

A useful record answers three questions before the customer arrives: who this is, what we did last time and what they care about. Everything else is either required paperwork or clutter.

The habit matters more than the software. A record filled in at the end of each visit, by the person who did the work, takes about a minute and stays accurate; a record updated at the end of the month from memory does not. Contact consent deserves its own field, because reminders depend on it: a Cochrane review of seven studies with 5,841 patients found 78.6% attendance with text reminders against 67.8% with none, and reminders can only go to customers whose numbers and permissions are on file.

Part 3 | How long to keep it, and how to keep it safe

Every record system needs a retention rule and a privacy rule, and both are set partly by law. For tax purposes, the IRS's guidance on how long to keep records gives these general periods.

SituationKeep records for
Most situations3 years
Employment tax recordsAt least 4 years after the tax is due or paid, whichever is later
Income underreported by more than 25% of gross income6 years
Claim for a loss from worthless securities or a bad debt deduction7 years
No return filed, or a fraudulent returnIndefinitely

Privacy rules depend on the trade. Dental and medical practices are covered by HIPAA and state medical record laws; tax preparers and bookkeepers have their own federal safeguarding duties; and every business holding customer data can use the Federal Trade Commission's guide for businesses, Protecting Personal Information, which organizes the work into five steps: take stock of what you hold, scale down to what you need, lock it, pitch what you no longer need and plan ahead for a breach.

The end-of-visit record checklist (copy and adapt)

  1. Confirm the phone number, email and reminder permission are current.
  2. Write today's service, who did it and the price.
  3. Add one technical note (formula, model number, procedure detail or filing status).
  4. Add one personal preference you learned today.
  5. Enter the next step with a date: rebook, maintenance, recall or deadline.
  6. File any required paperwork (estimate, consent form, engagement letter) to the same record.

How you compare

  • One place: count the places a single customer's details live today, such as the booking app, phone contacts, paper cards and texts; the target is one.
  • Completeness: pull ten recent customers at random and check how many have a next step with a date; if fewer than eight do, the end-of-visit habit is the place to start.
  • Reminders: compare your attendance rate with the 67.8% and 78.6% figures from the Cochrane review to see whether missing contact details are costing appointments.

Questions to ask this week

Where does a customer's history live right now? List every place, including people's memories.

Could a new employee greet a regular as if they knew them? Test it with one record on Saturday.

Which records are we required to keep, and for how long? Ask your accountant and, for practices, your compliance advisor to confirm the rules for your state and trade.

What do we hold that we no longer need? Old card numbers, outdated forms and former customers' documents past their retention period are candidates for secure disposal.

The next step is to choose one template from Exhibit 1, fill it in at the end of every visit for two weeks and then check ten records for completeness.

About this research: This article draws on research in the Journal of Consumer Research, PwC's 2018 consumer survey, a Cochrane systematic review of appointment reminders and official guidance from the IRS and the Federal Trade Commission. Retention periods are general IRS guidance; state law, professional rules and HIPAA can require longer periods for some businesses.
