Start Earning: How Smart Reordering Unlocks Hidden Profits in Your Hayati Range

Start Earning: How Smart Reordering Unlocks Hidden Profits in Your Hayati Range

Every week you place a wholesale order. Do you base it on data, or your instincts?

Most retailers reorder intuitively. They pick a few empty slots, chase their previous bestsellers, and hope the shelf manages to balance itself. It rarely does. You run out of your stars on Friday and have entire boxes of forgotten flavours on your Monday. Ordering in data transforms intuitive reorders into a powerful competitive edge. It is the cheapest edge to create - all you need is your sales log, and a few simple calculations.

This is most potent on high-demand brands, where Hayati can turbocharge your cashflow by turning your stock into cash within days. Poorly managed, the same range can swallow up hundreds of pounds in slow movers and unsold kits. It all depends on how you read the data. The same brand and the same supplier, but different management approaches.

The Anatomy of Retail Data: What to Look At

There are three main numbers you should be analysing to make sense of your inventory.

1. Sell-Through Rate (STR)

STR measures the percentage of stock sold within a time frame.
STR = Units sold ÷ (Units sold + Units left) × 100
If you started the month with 20 units and sold 15, your STR would be 75%. STR demonstrates your ability to turn stock into cash - the higher the STR, the better.

2. Days of Inventory (DOI)

DOI tells you how long your stock will last.
DOI = Stock on hand ÷ Average daily sales
If you have 10 units and sell two a day, you have five days of cover. Too few or too many days of cover means you are ordering incorrectly.

3. Gross Margin Return on Investment (GMROI)

GMROI is a profitability metric that measures gross profit per £1 of inventory.
GMROI = Gross profit ÷ Average inventory cost
If GMROI is 3, every £1 you invest in inventory produces £3 gross profit. This is a vital number to track.

Hero products vs shelf warmers

Sort your SKU list by STR and GMROI, then divide them into three categories.

  • Heroes: high STR, strong GMROI. Protect your stars and never let them run out.
  • Steady earners: moderate STR, reliable margin. Keep them lean and ensure consistent cover.
  • Shelf warmers: low STR, high DOI. Limit these on your shelves, and bundle or discard them.

    Heroes need constant stock, steady earners need lean but consistent cover, and shelf warmers should be limited, bundled or cleared to free up cash for winners.


Case Study: Maximizing the Hayati Ecosystem

The Hayati range covers four different types of income on vape devices, and each requires a slightly different approach. The numbers below are illustrative, so use your own costs and shelf prices.

Hayati Pro Max Pod System: The Steady Compounder

The device earns the first income, and the replacement pods every subsequent one. The consumer cycle is predictable, and you can plan your pod sales around known replacements. The margin per pod is not sensational, but repeat visitors cost nothing to acquire.

Data rule: Track weekly pod sales and set strict reorder limits. Browse the Pro Max 4K and Pro Max 6K ranges and maintain consistent cover on your top flavours. Predictability means low risk and high GMROI.

Hayati Pro Max Kit: The Velocity Play

The Pro Max kit delivers high early sales, particularly on new flavours. However, velocity is a double-edged sword. Flavor tastes change rapidly, and an over-ordered kit turns into a dead stock in weeks.

Data rule: Track weekly STR by flavor, and reorder winners in smaller, more frequent quantities. Cap any single flavor at approximately two weeks of DOI. New products on the new arrivals page should be tested at one pack of five before large follow-up orders.

Hayati Pro Ultra Pod System: The Premium Earner

This is your higher-ticket device, and it delivers superior gross profit per unit. Imagine a Pro Ultra pod earns £4 gross profit and sells 10 a week - versus a cheaper pod at £2 and 15 sales. This produces more overall profit (£40 versus £30) on less stock and fewer customer visits.

Data rule: Judge it on GMROI, not volume. Pro Ultra customers buy less frequently but spend more per visit. Focus on one or two proven flavours rather than cover the entire range.

Hayati Pro Ultra Kit: The Heavy-User Magnet

The 25,000-puff duo-tank style kit attracts heavy users who want to stretch their budget and enjoy two flavours. These are your highest-value customers, and your data will identify them.

Data rule: Register repeat buyers and their preferred flavor combinations. Place cover on your three bestselling pairings and track DOI ahead of every reorder, as packs of five represent more cash tied up per order. Capture these customers, and you will capture the largest baskets.

The strategy is to use kits to produce quick cash, and pod systems for compounding. A balance will create short-term and long-term income.

The Step-by-Step Data Reorder Formula

Apply this formula before placing a wholesale order.

Step 1: Pull your numbers.

List units sold per SKU for the past four weeks. Calculate average daily sales, STR and DOI for each SKU, and identify your heroes and shelf warmers.

Step 2: Set your reorder points.

Reorder point = (Average daily sales × Lead time in days) + Safety stock
If you sell three units a day, delivery takes two days, and you hold four units of safety stock, your reorder point is 10. When your stock reaches 10 units, it is time to order.

Step 3: Calculate your order quantity.

Order quantity = (Target days of cover × Daily sales) − Stock on hand
Aim for 7 to 10 days of cover on kits and around 14 on pod refills. Always confirm stock is compliant and correctly stamped, and our duty stamp guide will show you how.

Conclusion: Let the Numbers Build Your Wealth

Data, not instincts, fuels wealth creation in retail. That £1 wasted on a shelf warmer could have earned a place on a hero product. Your sales log contains all the insights, and the next step is to use them.

Start today. Audit your inventory log, calculate STR and DOI for your top 10 SKUs, and set your first reorder points. Then place a more intelligent Hayati order. If you are unfamiliar with our trade account, open your trade account and discover bestsellers first.
