Running a Customer Clinic or Open Day

A customer clinic or open day invites people in to get help, ask questions and see how you work, with no hard sell. Done well, it builds trust faster than any ad, because people leave having experienced your expertise for themselves. This guide shows you how to choose a format, plan the day, staff it safely and follow up so the goodwill turns into bookings.

Key takeaways

A clinic solves a specific problem for visitors; an open day shows them how your business works. Pick one clear purpose.
Use bookable slots for clinics so you can staff them properly and collect the details you need in advance.
Plan the practical side early: a run sheet, a simple risk check, accessibility and what happens if it rains or overruns.
The real value comes after the event, so plan your follow-up before the doors open.

February is a smart time for this. Many businesses are still in a quiet stretch, staff have a little more time, and customers are thinking about spring projects, new routines and fixing things that broke over winter. A clinic or open day gives them a reason to visit now rather than "sometime."

This is different from a general in-store event or a party. The focus is on helping people with something real and letting them see the skill behind your products or services.

Clinic or open day: choosing your format

The two formats overlap, but they work in different ways. Choosing one clear purpose makes every later decision easier.

Customer clinics

A clinic offers short, practical help sessions. Visitors bring a problem and leave with an answer or a fix. Examples include:

A bike shop running a basic brake and gear check.
A phone repair shop offering free diagnostics or "learn your settings" sessions.
A garden center hosting a pruning and soil advice clinic.
An accountant or bookkeeper offering short "bring your questions" slots before a tax deadline, with general guidance only.
A yarn or sewing shop running a "rescue your project" table.
A software company holding a drop-in help session for existing customers.

Open days

An open day lets people look behind the scenes. They meet the team, see the workshop, kitchen or studio, try things and ask questions. It suits makers, studios, training providers, clinics, gyms, schools and any business where people want to know what they are signing up for before they commit.

Mixing the two

Many businesses run an open day with a clinic table in one corner. That works, as long as you staff each part separately so the clinic does not swallow the whole team.

Pro tip

Look at your most common customer questions over the past few months. The question you answer every week is the perfect clinic theme, because you already know people want help with it.

Planning the day step by step

Give yourself about four to six weeks for a first event. That leaves time to promote it and sort the practical details without a scramble.

Set one goal. New customers, more bookings for a service, a list of interested people, or happier existing customers. Write it down.
Pick a date and time. Avoid your busiest trading hours. A weekday evening or a quiet Saturday morning often works. Check local events that might clash or help.
Decide the capacity. How many people can you help or host well at once? Clinics usually work best as slots of 10 to 20 minutes.
Set up bookings. Use a booking tool or a simple form to collect names, contact details and a short description of the problem.
Plan the layout. Mark a welcome point, a waiting area, clinic stations or demo zones, and a quiet corner for longer chats.
Brief your team. Share the run sheet, who does what, and how to handle sales questions without pushing.
Promote it. Tell existing customers first, then post on social media and your Google Business Profile.
Prepare follow-up. Draft the thank-you email and any offer before the day, so it goes out within 48 hours.

A run sheet template

A run sheet keeps everyone calm on the day. The times and roles below are made-up examples for a three-hour Saturday clinic.

Time	What happens	Who	Notes
9:00	Set up stations, signs and sign-in sheet	All staff	Check booking list and print a copy
10:00 to 12:30	Clinic slots, 15 minutes each	Two specialists	Greeter keeps time and manages walk-ins
11:00	Short group demo	Owner	Ten minutes, then questions
12:30 to 13:00	Wrap up, collect feedback cards, tidy	All staff	Note anyone who wants a follow-up call

Bookings, walk-ins and capacity

Bookings help you plan staff, avoid long queues and learn about each visitor's problem in advance. Booking tools such as Calendly, Acuity Scheduling, Square Appointments and SimplyBook.me can handle slots and reminders. A form from Google Forms or Tally works if you just need a list. Check current features, pricing and privacy policies before choosing one.

Leave some room for walk-ins, because neighbors and passers-by will wander in. A simple rule helps: walk-ins get the next free slot or a quick chat at the welcome point, and the greeter offers to book them a proper slot later.

Ask just enough at booking. Name, email or phone, and one line about what they need help with.
Send a reminder. A message the day before reduces no-shows and lets people cancel so you can fill the slot.
Overbook gently, if at all. A small buffer for no-shows is fine, but long waits undo the goodwill you are building.

Common mistake

Turning the clinic into a sales pitch. If every answer ends with "so you should buy this," visitors feel tricked and will not come back. Help first. Mention a product or service only when it genuinely solves the problem, and make it easy to say "no thanks."

Safety, access and the practical details

Inviting the public into a workshop, kitchen or studio means thinking about safety a little differently than on a normal trading day. Visitors may wander into areas customers do not usually see, and children may come along.

Walk the route. Look for trip hazards, sharp tools, hot surfaces, chemicals and machinery. Rope off or close anything visitors should not touch.
Update your risk assessment. In the UK, employers with 5 or more employees must have a written risk assessment and health and safety policy under the Health and Safety at Work Act, so add the event to it. In the US, OSHA's general duty clause expects employers to keep the workplace free of recognized hazards. Smaller businesses benefit from the same thinking even where a written record is not required.
Check your insurance. Ask your insurer whether your public liability or general liability cover includes events and demonstrations on your premises.
Think about access. Step-free entry, seating, clear signs and a quiet space make the day welcoming for more people. Say on the booking page what access is available.
Plan for winter weather. Have a mat by the door, a place for wet coats and a backup plan if snow or ice makes travel hard.
Food and drink. If you offer snacks, keep it simple and label allergens. Serving food more widely may bring extra rules, so check with your local authority.

This is general information, not legal or insurance advice. Check local rules and speak to your insurer or a qualified adviser if you are unsure.

Photos and permissions

Events make great content, but get permission before you photograph visitors or reuse their posts and photos. A small sign at the entrance plus a verbal check works well, and never post images of children without a parent's clear agreement.

Promoting your clinic or open day

Start with the people who already like you. Existing customers are the most likely to come and the most likely to bring a friend.

Email your list. Lead with the problem you will help solve, the date and the booking link. Remember US CAN-SPAM rules require an unsubscribe option and a postal address, and UK and EU consent rules apply to marketing emails.
Post an event on your Google Business Profile. It lets you publish events and updates where local searchers will see them.
Use social media. Show the space and the people who will be helping. Tools such as Buffer, Later or Meta Business Suite can schedule posts in advance.
Put a sign in your window two to three weeks before the date.
Ask partners. A neighboring business, a club or a community group may share it with their members.

Hypothetical example

Imagine Priya, who runs a small bike shop. In early February she holds a "spring ready" clinic on a Saturday morning with 15-minute slots for basic safety checks. She emails past customers, posts the event on her Google Business Profile and puts a poster in the window. Visitors book their problem in advance, so her mechanic knows to expect sticky gears and worn brake pads. Each visitor leaves with a printed checklist of what was looked at and what might need work later. Over the next few weeks, a good number of them book a full service, and several bring their family's bikes too.

Following up after the event

The day itself is only half the job. Follow-up is where clinics and open days pay off.

Send thanks within 48 hours. Thank people for coming, recap one useful tip and include a simple next step, such as a booking link.
Keep promises. If you said you would send a quote, a guide or a call, log it and do it.
Ask for feedback. Two or three questions are enough: what helped, what was missing and whether they would come again.
Count results. Note bookings, sales, new subscribers and repeat questions. Compare them with the goal you set.
Decide on the next one. If it worked, put the next date in the calendar while the details are fresh.

Frequently asked questions

Should a customer clinic be free?

Most are free, because the aim is to build trust and show your expertise. Some businesses charge a small fee that is credited against a later purchase, which can reduce no-shows. Choose whichever fits your goal and say clearly on the booking page what is included.

How long should an open day last?

Two to four hours is usually enough. Shorter events feel busier and are easier to staff. If you want to reach people with different schedules, try two short sessions on different days rather than one long one.

What if hardly anyone books?

Do not cancel too early. Many people decide in the last few days. Send a reminder to your list, post again and ask staff to mention it to customers. If numbers stay low, run it anyway as a smaller, more personal session and learn from it.

How often should I run one?

Many small businesses find that a few times a year works well, tied to seasons or common problems. Regular events build a following, but too many can feel routine. Let your results guide the rhythm.

The bottom line

A customer clinic or open day works because it leads with help. Choose one clear purpose, use bookable slots, plan the safety and practical details, and keep the sales talk gentle. Then follow up quickly so the trust you built on the day turns into bookings, sales and loyal customers.

Look at the question your customers ask most often, and pencil in a date for a clinic that answers it. Your first one does not need to be big. It just needs to be genuinely useful.
