Salon Stock Control: A Simple System That Saves Money

Few things knock a salon day off course like reaching for a tube of colour, a bottle of gel top coat or a pot of wax and finding it empty. Good salon stock control stops that from happening, and it does more besides: it frees up cash that would otherwise sit on a shelf, cuts waste from out-of-date products, and makes ordering a quick weekly job rather than a panic. This guide walks you through a simple system that works for a one-chair studio or a busy salon with a team, without needing expensive software.

Why salon stock control matters more than you think

Stock is money in a different form. Every box of developer, every case of retail shampoo and every spare packet of lash glue is cash you have already spent. When there is too much of it, your bank balance suffers. When there is too little, you lose bookings, rush to the wholesaler at full price, or quietly swap in a product you would rather not use.

Getting the balance right brings several benefits at once:

• You stop running out of the products your most popular services depend on.
• You spend less on emergency trips and last-minute deliveries.
• Less product goes past its use-by date or dries out at the back of a cupboard.
• Your cash flow improves because less money is tied up in stock.
• You can see what is actually used, which helps when you price services.
• Your team wastes less time hunting for things.

It also protects the client experience. A client who booked a particular colour or treatment and is told "we've run out" is far more likely to drift off to someone else.

Know what you have: back-bar, retail and consumables

Before you set any levels, sort your stock into groups. Most salons have three.

Back-bar products

These are the professional products used during services: colour, developer, lightener, toners, gel and acrylic systems, wax, lash and brow tints, massage oils, skincare used in facials. They are usually your biggest stock cost and the ones that hurt most when they run out.

Retail products

These are the items clients take home: shampoo, styling products, cuticle oil, aftercare, gift sets. They earn money directly, but they also tie up cash and shelf space. Slow-selling retail is one of the most common hidden costs in a salon.

Consumables and sundries

Foils, gloves, towels, cotton pads, spatulas, nail files, couch roll, disinfectant, cleaning products. They are cheap one by one but add up quickly, and running out of gloves or couch roll can stop a service as surely as running out of colour.

Once everything is grouped, do a full count. Write down every product, how many you have, what each one costs you and where it is kept. It is tedious the first time, but it gives you a baseline. A shared spreadsheet or even a printed sheet on a clipboard is enough to start.

Set a minimum level for every key product

The heart of salon stock control is the minimum level: the amount of a product you need to have on hand to keep working until your next delivery arrives. When stock drops to that level, you reorder.

To work it out for each product, you need two things.

1. How long a delivery takes. If your wholesaler delivers within two days, that is your lead time. If you only order once a week, your real lead time is up to a week plus delivery.
2. How quickly you use it. Look back over a few normal weeks. How many tubes of your best-selling brown shade went? How many pots of wax? Divide by the number of working days to get an average daily use.

Multiply the two together and you have your basic minimum. If you use roughly one tube of a shade a day and deliveries take three days, you need at least three tubes on the shelf when you reorder.

Add a safety buffer

Then add a little extra for the unexpected: a supplier running late, a run of colour corrections, a busy week before a bank holiday. How big that buffer should be depends on how critical the product is. A shade you use on half your clients deserves a generous buffer. A seasonal nail colour does not.

Not every product needs the same attention

Rank your products by how important they are and how fast they move:

• Essentials that you use every day and cannot work without. Check these weekly and keep a buffer.
• Regular items that move steadily. Check these every week or two.
• Slow movers and occasional items. Keep only what you need for the next few bookings, or order them when a client books the service.

Write the minimum level on a label on the shelf or on the stock sheet, so anyone in the team can see at a glance when something needs reordering.

Plan your buying instead of reacting

Once you know your minimums, ordering becomes a routine rather than an emergency. A few habits make a big difference.

Pick one ordering day

Choose a quiet time each week, such as Monday morning, to check stock and place orders. Go down your list, compare what is on the shelf with the minimum, and order whatever has dropped below it. Doing this on the same day each week means nothing slips through.

Set a stock budget

Decide roughly how much you are willing to spend on stock each month, based on your bookings and your past spending. A budget stops you from over-ordering because a rep offered a deal, and it makes it obvious when your product costs are creeping up.

Look ahead to busy seasons

Your diary tells you what is coming. Prom season means more updos, lashes and nails. Wedding season brings trials and bridal parties. The weeks before Christmas and New Year are usually the busiest of all, and Mothering Sunday and Black Friday can bring a rush of gift vouchers and retail sales. Look back at what you used in the same weeks last year and order non-perishable items early, while keeping fresher items on smaller, more frequent orders. Our salon marketing calendar for the UK can help you map out the year.

Watch for slow retail

Check retail sales every month. If a product has barely moved in a couple of months, stop reordering it. Move it to a more visible spot, recommend it where it genuinely suits a client, or bundle it with a service. If it still does not sell, clear it and do not buy it again.

Work well with your suppliers

A good relationship with your wholesaler or brand rep is worth a lot. You are a regular customer, and that gives you room to ask for things.

• Ask about payment terms. Some suppliers will let established accounts pay at the end of the month, which helps cash flow.
• Ask about smaller, more frequent deliveries. For products that expire or that you have little room for, this beats one big order.
• Be wary of bulk deals. A discount for buying a large quantity only saves money if you will use it all before it expires and you have the cash and space to hold it.
• Compare suppliers now and then. You do not need to switch often, but checking prices once or twice a year keeps everyone honest.
• Have a back-up. Know where you could get your essentials quickly if your usual supplier lets you down.

Keep a simple note of each supplier's contact details, delivery days, minimum order and any agreed terms, so anyone covering for you can place an order.

Cut waste and keep products in good condition

Waste is stock control's quiet enemy. A few routines keep it down.

First in, first out

When a delivery arrives, put the new stock at the back and move the older stock to the front. That way the oldest products are used first. It sounds obvious, but in a busy salon new boxes often get stacked on top and the old ones sit there until they expire.

Check dates and opening times

Many beauty products carry a "period after opening" symbol, the small open jar with a number of months on it. Write the date you opened a product on the label so you know when it should be replaced. Check back-bar shelves once a month for anything close to its date.

Measure, don't guess

Over-mixing colour, pumping too much product or using a fresh bowl of wax for every small area all add up. Agree standard amounts for common services, use scales for colour where it makes sense, and show new team members how much to use.

Store products properly

Keep products away from heat, direct sunlight and damp. Store chemicals safely and in line with your COSHH assessment, with safety data sheets to hand. Keep the stock room tidy and labelled, so things are easy to find and nothing is forgotten in a corner.

Get your team involved

Stock control falls apart if only one person cares about it. Give someone clear responsibility for receiving deliveries, checking them against the order and putting them away in the right place. Ask everyone to tell that person, or write on a shared list, when they open the last of something or notice a product running low.

Explain why it matters. When the team understands that waste and empty shelves cost the business money, and that running out spoils a client's appointment, most people are happy to help. Recognise good habits, and ask for ideas: the people using the products every day often know best where waste happens.

Review and adjust regularly

Your minimum levels are not set in stone. Services change, new products come in, and your client base grows or shifts. Every few months, look at:

• Which products ran out, and whether their minimum needs raising.
• Which products are piling up, and whether their minimum should come down.
• How your total stock spend compares with your takings.
• Which retail lines are earning their shelf space.

Comparing product costs with what you charge is especially useful. If a service now uses more or pricier product than when you set its price, it may be time to review it. Our guide to reducing salon costs and our list of salon KPIs go into this in more detail.

Keep your stock records tidy for another reason too: your accountant will usually want a stock figure at the end of your financial year, and a regular count makes that easy.

Putting it all together

Good salon stock control is not complicated. Count what you have, set a minimum for each key product, order on the same day every week, use the oldest stock first, and review your levels every few months. Within a few weeks you will spend less time worrying about empty shelves and more time with clients.

Stock planning is easier when you know how busy you will be. If you use Repeatfy to see which clients are regulars and which are slipping away, you get a clearer sense of who is likely to book in the coming weeks, which makes ordering less of a guess. And if you want to sell more of the retail you already stock, our guide to increasing average spend in a salon has practical ideas.

Frequently asked questions

How often should a salon do a stock take?

A quick check of your essential products once a week, on your ordering day, is enough for most salons. A full count of everything, including retail and sundries, once a month or once a quarter keeps your records accurate and shows up slow-moving lines.

Do I need stock control software for my salon?

Not to start with. A clear spreadsheet or printed stock sheet with minimum levels works well for small salons. Software becomes more useful as your range grows or you add more staff, but the habits matter more than the tool.

How do I stop running out of colour?

Work out how quickly you use each shade and how long deliveries take, then set a minimum level with a small buffer for your most popular shades. Check those shades every week and reorder as soon as they drop to the minimum.

What should I do with retail stock that isn't selling?

Stop reordering it first. Then move it somewhere more visible, recommend it only where it suits the client, or bundle it with a service. If it still does not sell within a sensible time, clear it at a reduced price and use the space for something that does.
