How to Manage Stock Levels for Your Retail Shop (And Never Oversell)

1. 01

   Step 1: Start with a complete physical count

   

   Before you can track stock, you need to know what you have. Set aside two hours and count everything in your shop, storage room, and back stock. Use a clipboard or spreadsheet with three columns: item name, current count, and notes. Don't estimate—physically touch and count each item. If you sell clothing, count by size and color. For packaged goods, check expiration dates and note anything damaged or unsellable. This baseline is critical. If your starting count is wrong, every update after that will be off. Do this on a slow day or after hours so you're not interrupted.

   Step 2: Set up your inventory in your selling system

   

   Once you know what you have, enter it into whatever system you use to sell. If you're on Lumo, open your shop, tap each product, and set the stock quantity. If you sell in person too, use a notebook or simple spreadsheet that you update after every sale. The key is one source of truth—a single place where your current stock lives. For each item, note not just the quantity but also any variants (size, color, flavor). If you make 12 bars of lavender soap and 8 bars of peppermint, track them separately. Generic counts lead to overselling. Update this list every single day, ideally at the end of your business day, so you start each morning knowing exactly what's available.

   Step 3: Update stock immediately after every sale

   

   The moment an item sells—online or in person—subtract it from your stock count. If you're using an app like Lumo, the platform does this automatically when an order comes in. If you sell at farmers' markets or in a physical shop, keep a tally sheet at your register or on your phone and update your main inventory at the end of each day. The longer you wait, the more likely you'll forget a sale or sell the same item twice. Set a daily alarm for 8 p.m. as a reminder to reconcile your counts. If you have help, train anyone who handles sales to update stock or at least record what sold so you can update it later.

   Step 4: Set low-stock alerts so you don't run dry

   

   Decide on a minimum threshold for each product—the point where you need to reorder or make more. For a bakery, that might be five loaves; for a clothing boutique, two items per size. Write these thresholds down. Check your stock against them once a week. Some selling platforms let you set automatic alerts, but even a simple spreadsheet with conditional formatting (cells turn red when you hit the threshold) works. Running out isn't always bad, but not knowing you're about to run out is. Build in lead time: if it takes your supplier four days to restock, set your alert for five or six items left, not zero.

   Step 5: Turn off listings when you're out of stock

   

   The instant you sell the last unit of something, make it unavailable for purchase. On Lumo, you can set stock to zero or pause the listing. If you sell on multiple platforms, update all of them. Don't leave a listing up hoping you'll restock tomorrow—customers order now, not tomorrow. If an item is temporarily out but coming back soon, add a note to the description ('Back in stock April 10') and turn off ordering. If it's gone for good, delete the listing or mark it as sold out permanently. This takes 30 seconds and prevents the headache of refunding orders and apologizing to frustrated buyers.

   Step 6: Do a weekly physical recount to catch mistakes

   

   Even with careful tracking, errors creep in—someone forgets to log a sale, a jar breaks, a customer returns an item. Once a week, pick five to ten of your best-selling items and recount them physically. Compare the actual count to what your system says. If they don't match, investigate. Did you forget to log a sale? Did someone shoplift? Was there a return you didn't add back? Adjust your system to match reality, not the other way around. For smaller shops, a full monthly recount of everything is smart. Mark it on your calendar like any other business task. These recounts are your safety net—they keep small mistakes from snowballing into big ones.

   Step 7: Communicate clearly when stock is limited

   

   If you only have three left of a popular item, say so in the listing: 'Only 3 available' or 'Limited stock.' Customers appreciate transparency, and it can even create urgency that boosts sales. If someone orders multiple units and you're low, message them before confirming: 'I have two in stock right now; I can get the third by Friday—does that work?' Most people would rather wait a day or adjust their order than have it canceled. On Lumo, use the in-app messaging to confirm details before you mark an order as confirmed. Honest communication turns a potential complaint into a loyal customer who knows you're paying attention.
