Most ski, snowboard and bike rentals start with a notebook at the counter and a price list taped to the wall, and later move to a spreadsheet on the shop computer: one row per booking, or one row per pair of skis or bike with the days colored in. For years it works. Then comes the week between Christmas and New Year, or the first hot weekend of the bike season, with three people at the counter and a queue out the door, and the notebook becomes the busiest and least reliable thing in the shop.
For some shops that is still the right setup. This article covers what a rental shop has to keep track of, when a notebook or Excel handles that well enough, where it breaks, and how to switch without losing a season. Skis, snowboards and bikes run into the same problems, so the examples below mix them.
What a ski or bike rental has to keep track of
Whatever you run it on, a rental shop has to answer these questions every day.
- What do we own? Every model in every size, and how many pairs of skis, boards or bikes of each are in service.
- What is booked for which dates? Who reserved what, from when to when, and whether it's paid.
- Who has what right now? Which customer left with which skis or bike, when it's due back, and what deposit they left.
- What does it cost? The price for an hour, a day or a week, and the surcharge in high season.
- What needs attention? Which skis need a grind, which bike needs new brake pads, which boot is missing a buckle.
A notebook answers each of these as long as one person writes everything down and remembers the rest. The trouble starts when the answers have to be combined. Whether a 170 cm pair of skis or a size M e-bike is free from Monday to Friday depends on the first three at once: what you own, what's booked, and what hasn't come back.
When a notebook or Excel is enough
A notebook or a spreadsheet does the job when most of these are true:
- Most rentals are walk-ins for the day, and the gear comes back the same evening. The rack shows what's available: if it's on the rack, it's free.
- Bookings ahead are few, and they come by phone to one person.
- There is one counter, and everyone writes in the same place.
- You don't take online bookings with payment and don't plan to.
- The fleet is small enough to check a size by walking to the rack.
A shop like that loses little by running on paper. Software would still speed up the counter, but the gain is small, and a subscription to replace a notebook that works is hard to justify. If this describes your shop, keep the notebook and come back to this article in the season you start taking bookings ahead.
Signs your rental shop has outgrown Excel
You take bookings for dates ahead, in specific sizes
This is where a spreadsheet goes wrong first, and nobody notices when it does. Take a model you have two of in one size, say two pairs of skis in 170 cm; two size M e-bikes behave exactly the same way. Anna books Monday to Tuesday and goes on pair 1. Ben books Wednesday to Thursday, and whoever takes his call writes him on pair 2.
170 cm | Mon | Tue | Wed | Thu | Fri |
|---|---|---|---|---|---|
Pair 1 | Anna | Anna | |||
Pair 2 | Ben | Ben |
A third customer asks for Monday to Friday. No row is free all week, so the answer on the phone is no. The correct answer is yes: Anna and Ben never need skis on the same day, so both fit on pair 1, and pair 2 is free all week. Counting bookings instead of reading rows gets it wrong too, since two bookings overlap those dates and a count says both pairs are taken.
The question that gives the right answer is how many are out on the busiest day of the requested dates. Here that's one, so one of the two is free. With two you can work it out in your head. With fourteen pairs in 170 cm and forty bookings over the holidays, or a fleet of e-bikes on a long weekend, nobody does, and the shop turns away rentals it could have served.
More than one person or channel takes bookings
The phone at the counter, the owner's mobile, an email inbox, a message on Instagram, a customer standing at the counter: each is a place where a booking is made, and a notebook sits in one place. When the owner takes a booking away from the shop and writes it in an hour later, the gear looks free in the notebook for that hour. A shared Google Sheet helps because everyone sees the same file, but nothing in it stops two people writing the same bike for the same days. A double booking is usually two correct bookings, made in two places before anyone compared them.
The paperwork happens in the morning queue
In the morning rush, each customer at the counter is a name to find, a phone number to write down, the skis or bike to note, a price to calculate and a deposit to record. Every line written by hand is written while the queue waits. A four-day ski rental on a price list with a 3-day and a 7-day price, or a three-hour bike rental on a list with two-hour and half-day prices, is arithmetic done at the counter, and two people won't always get the same total.
In rental software, a booking made ahead is already on the screen with its price calculated, and handing out skis or a bike is a scan of its tag or a click.
You find out about late gear when the next customer arrives
A bike due back on Sunday that isn't back on Sunday is a problem for whoever booked it from Monday. With a notebook, nobody sees that until Monday morning, when the customer is at the counter and the bike isn't in the rack. A spreadsheet can show it if someone updates the row at every return, and in peak week nobody does. Rental software that tracks returns lists what is overdue on its own and keeps counting a late bike as out, so it isn't promised to the next customer.
Damage works the same way. A note that a binding came back loose or a brake is rubbing only helps if whoever hands that gear out next sees it.
You can't see the shop unless you're in it
The notebook is on the counter and the spreadsheet is on the shop computer. From home in the evening, or out on the slope or the trail, the owner can't see tomorrow's pickups or check whether Saturday's takings add up. A program installed on one computer has the same limit, however modern it looks. A spreadsheet in the cloud fixes the access and nothing else on this list.
A notebook also rules out online booking. A customer booking online needs availability checked at that moment, and a notebook can't be asked. If you want online bookings, the inventory has to be in software first. Whether you then need a website of your own is covered in does a ski rental shop need its own website.
Notebook, Excel or rental software: side by side
Notebook | Excel or Sheets | Rental software | |
|---|---|---|---|
Is a size free for a date range | Checked by eye | Checked by eye, row by row | Calculated when the booking is made |
Two people booking at once | One notebook, one pen | Same file, nothing stops a clash | Every booking checks the same stock |
Online booking with payment | No | No | In most, sometimes as an add-on |
What each customer has | Written by hand | Typed by hand | Scanned or picked at hand-out |
Late returns | Noticed when someone looks | Visible if every return is entered | Listed automatically |
Price for a four-day rental | Price list and a calculator | A formula, if someone wrote one | Calculated from the price list |
Away from the shop | No | Yes, if the sheet is in the cloud | Yes, if it runs in a browser |
Cost | A notebook | Free, or part of an office suite | A monthly subscription |
A notebook costs nothing and a spreadsheet next to nothing. Rental software is a monthly subscription, and prices vary widely. It pays for availability over a date range, one stock shared by every channel, and paperwork done before the customer reaches the counter. What the main products cost and include is in our rental software comparison for 2026/27.
How to switch from Excel to rental software before the season
- Pick the month. A month or two before your busy season: October or November for skis and snowboards, March or April for bikes. The gear is in the racks and the counter is quiet, so a mistake costs an afternoon instead of a queue. The week before the season opens is the worst time to learn a new system.
- Count what you own. One line per model and size, with the number of pairs, boards and bikes in service. It doubles as the stock check you'd do before the season anyway.
- Tag everything you rent out. A serial number or a barcode sticker on every pair of skis, board and bike, so the system records what went to which customer. That's what makes a late return or a damaged binding traceable to one item.
- Write the price list as durations. An hour, half a day, a day, three days, a week, whichever you rent by, plus what each extra hour or day costs, with the high-season surcharge as a separate rule. Most rental software expects prices in that shape.
- Enter the bookings you already hold. Everything taken for the season so far goes in before the first new booking, or availability is wrong from day one.
- Put the notebook away. Run one weekend with both if you need to, then stop writing in it. Two systems in parallel bring back the double bookings the switch was meant to end.
Before you pick a product, ask the vendor whether it can import your spreadsheet and how long entering a fleet of your size usually takes.
How Rentouri does it
Rentouri answers the question from the Anna and Ben example for you. Bookings taken in the shop, by phone and on rentouri.com come off one stock count, kept separately for each model and size, and late gear blocks new bookings until it's checked back in. The exact pair of skis or bike is assigned at hand-out, when you scan its tag. It runs in the browser, so you see tomorrow's pickups and today's returns on your phone.
Customers book and pay on their own. They pick the model and size on rentouri.com, sign the rental agreement and pay by card, and you paste the link to that page into your Google listing. A call you miss at the peak no longer means a lost booking.
The morning queue moves faster. The customer arrives with the QR code from their confirmation email. Scanning it opens the booking with the price already calculated, and scanning the tag records which pair went out. If someone reaches for the wrong size, the system asks before swapping it.
We handle the switch. We add your gear, sizes and prices for you from your spreadsheet, notebook or printed price list, as part of the subscription. We also set up your opening hours, deposit and rental agreement.
No contract, cancel anytime. The 5–7% commission applies only to bookings from rentouri.com; bookings in the shop and by phone carry none.
