Stock a smart cooler for the people at that one location: start with cold drinks and shelf-stable snacks, add fresh or frozen items only where there is steady demand, set a par level for each product from its sales, rotate oldest-first, and replace the slowest sellers on a schedule.
This is a working reference. It covers what to stock by location type, how to plan shelves and facings, how to control fresh food spoilage, frozen notes, how to set starting quantities, and how to test and replace products.

Before you stock anything
- Add every product to the cooler’s product library first. The AI recognizes items by matching them to products you set up in the app with a name and price. On HAHA, merchants create these product templates before selling.
- Follow your brand’s stocking guide. HAHA keeps its software manual, including stocking and restocking, in the app’s Support channel.
- Check the rules for food. Fresh food often needs a permit or a licensed supplier or commissary. Ask your local health department before you stock it.
- Know your capacity. Vendera lists the Core LC-510 at 400+ products, the Atlas LC-1160 at 672+ and the Arctic LD-315 freezer at 240+. HAHA publishes per-model bottle counts on its site.
What to stock by location type
| Location | Core items | Add once demand is clear | Watch out for |
|---|---|---|---|
| Office | Water, sparkling water, soda, cold coffee, yogurt, snacks | Sandwiches, salads, wraps for lunch | Low weekend sales; a nearby cafeteria |
| Gym | Water, electrolyte and sports drinks, protein shakes, protein bars | Frozen protein treats, high-protein snacks | Peak hours around classes; members who bring their own drinks |
| Warehouse / factory | Water, energy drinks, sports drinks, hearty snacks, jerky | Larger meals, breakfast items for early shifts | Shift changes drive bursts; plan stock for all shifts |
| Hospital / clinic | Water, juice, coffee drinks, yogurt, lighter snacks | Fresh meals for night staff | Facility rules on healthier options; 24-hour demand |
| School / campus | Water, sports drinks, snacks, protein bars | Grab-and-go meals, frozen treats | K-12 schools may follow USDA Smart Snacks nutrition standards during the school day; check with the district |
| Apartments | Drinks, snacks, quick-meal basics | Frozen meals, ice cream | Evening and weekend demand |
| Hotel | Water, soda, snacks, treats | Grab-and-go meals, frozen items | Guests change daily; keep familiar brands |

Categories, shelves and facings
A facing is one front-row spot for a product. More facings make a product easier to see and slower to sell out.
- Give your expected top sellers two or more facings so the shelf never looks empty.
- Keep each product in the same spot every visit. Customers learn where things are, and your restock stays fast.
- Group by category: drinks together, snacks together, fresh food together.
- Put the items you most want to sell where customers look first when the door opens.
- Do not block the view of other products. The cameras need to see what is taken.
Suggested starting split for a typical office cooler (a planning assumption, not sales data):
| Category | Share of facings | Adjust when |
|---|---|---|
| Cold drinks | 50% | Drinks sell out before the next visit |
| Snacks and bars | 25% | Snacks sit while drinks move |
| Dairy and protein (yogurt, shakes) | 15% | Dates expire before items sell |
| Fresh food | 10% | Steady sales for 2–3 weeks before you add more |
Fresh food: shelf life and spoilage control
Fresh food can raise the average sale, but it is where most waste comes from. Shelf life depends on the item and the supplier, so use the date code on the package, not a general rule.
- Order to the date. Buy only what you expect to sell before the date at your visit schedule.
- Start small. A few items, a few units each, until you see what moves.
- Pull before it expires. Remove anything at or past its date on every visit.
- Log every item you throw away. Waste you do not track is waste you keep repeating.
- Watch the temperature. HAHA notes that actual temperature cycles around the target, normally within about 8°F. Know your model’s range and set outage alerts in the app.
- Use a licensed source. Buy from a supplier or commissary that meets your local health rules.
Frozen products
Frozen items need a freezer model. Do not put them in a standard cooler.
- Vendera Arctic LD-315: freezer, down to −13°F, 240+ products (vendera.ai).
- HAHA Freezer 550: HAHA’s dual-mode model, listed at 19.4 cu ft on Smart Cooler Supply. You choose its mode: −7.6°F to 14°F as a freezer or 32–50°F as a refrigerator.
Good frozen candidates are ice cream bars, frozen protein treats and frozen meals where people can heat them. Carry frozen stock in insulated bins and load it first. If a freezer loses power, follow your supplier’s and health department’s guidance before you sell anything that may have thawed.

Starting quantities and par levels
A par level is the number of units you fill each product back up to on every visit. Set it from sales velocity, not from someone else’s sales numbers.
Week one: no history yet
Fill shelf-stable drinks and snacks to their facings. Keep fresh items to a few units each. Your cooler’s app will start reporting what sells.
After two to three weeks: set real pars
Par = average units sold per day × days between visits + safety stock.
Illustrative example — replace with your own numbers. Assumptions: one bottled water sells 4 a day, you restock every 3 days, and you keep 1 day of safety stock.
| Step | Units |
|---|---|
| Daily sales × days between visits (4 × 3) | 12 |
| Safety stock (1 day × 4) | 4 |
| Par level | 16 |
For fresh food, use little or no safety stock, because leftovers expire. If a par will not fit the space you gave it, add facings or visit more often. Vendera’s software builds pick lists from live inventory, which makes this faster on restock day.
Rotation: first in, first out
- Move older units to the front before you load new ones behind them.
- Check dates on every visit, not just on fresh food.
- Store backup stock in date order so the oldest leaves your storage first too.
Testing and replacing slow movers
Your opening mix is a guess. Use the sales report to improve it on a schedule.
- Review every two to four weeks. Rank products by units sold per week.
- Flag the bottom few. Look at margin too; a slow item with a strong margin may stay.
- Replace one or two at a time. Changing everything at once hides what worked.
- Give each test the same window. Compare new items over the same number of weeks.
- Keep a simple test log: product, date added, units per week, result.
Price affects what moves, so set prices with the smart cooler pricing strategy guide. To see whether the location pays after product cost, fees, spoilage and your time, use the free ROI Calculator. These are planning figures, not earnings promises; see our earnings disclaimer.
Using the Product Mix and Planogram apps
The free Product Mix app asks 15 quick questions about your location, customers, traffic and goals and gives you a preview of a recommended mix. It covers offices, gyms, schools, hospitals, apartments, warehouses and more. Treat it as a starting plan you adjust for local demand, supplier availability and spoilage.
Members get the full plan, including starter products, a shelf-by-shelf layout, pricing and restocking guidance. The member Planogram app then maps where each product goes on each shelf. After that, plan your service runs with the free RouteReady route planner. Membership is $49 a month or $349 a year and includes every app and course; see membership.

Frequently asked questions
What sells best in a smart cooler?
It depends on the location. Start with cold drinks and shelf-stable snacks that fit the audience, then let your own sales report show what to add or cut.
How many of each item should I stock?
Set a par level: average units sold per day times days between visits, plus a small safety stock. Use little or no safety stock for fresh food.
Can I sell fresh food in a smart cooler?
Yes, where there is steady demand and your local rules allow it. Use a licensed supplier, order to the date code, rotate oldest-first and log waste.
Do I need a freezer model for ice cream?
Yes. Use a freezer such as the Vendera Arctic LD-315 or the HAHA Freezer 550. A standard cooler is not built to hold frozen product.
How often should I change the product mix?
Review sales every two to four weeks and replace one or two slow movers at a time, so you can tell which change made the difference.
