Watch a busy shop for ten minutes and you’ll see the same small ritual over and over. A customer asks for 5kg of shea butter. The owner pauses, glances at the shelf, walks to the back, checks, comes back. “Let me weigh it.” A sale happens. Maybe it gets written in the book. Maybe it waits for a quieter moment that never comes.
None of this is laziness. It’s the tool. A notebook can’t tell you what’s on the shelf without you walking to look. It can’t do the maths on a repacked bag. And it certainly can’t tell you, at the end of the day, whether you actually made money or just moved a lot of stock around.
Today that tool gets an upgrade. Mayloo — the app that tracks your stock and shows your real profit — is now on Android. The whole thing. In your pocket. On the phone you already carry around the shop all day.
Why Mayloo, and why this matters for your shop
There is no shortage of apps that let you type in a product and a price. That part is easy. The reason most of them get downloaded and quietly abandoned is that they fall apart the moment your shop works the way real Nigerian shops work.
You buy shea butter by the 25kg sack and sell it in 500g bags. You buy essential oil by the litre and decant it into 100ml bottles. You buy in bulk and sell in pieces, and every time you break bulk, a little stays on the scoop and the scale. Ask most apps for your real profit on that 500g bag and they can’t give it to you. They use an average cost, they ignore the spillage, and they hand you a number that looks clean and is wrong.
Mayloo was built for exactly this — starting with the hardest sellers to get right, the cosmetics raw-material traders whose stock maths defeats everyone else. It tracks stock down to the gram and the millilitre. It converts between how you buy and how you sell. And it costs every sale against the actual batch it came from, not a blended average, so the profit you see is the profit you kept.
That’s the whole point. Not prettier charts. Numbers you can trust enough to spend.
Record a sale in about 30 seconds
The counter is where a shop lives or dies, so that’s where the Android app is fastest. Your staff tap the product, choose the unit — 500g, one piece, a full carton — and Mayloo does the maths. No calculator. No sums in your head while a customer waits and the queue grows. Cash or transfer, one item or ten, the sale is saved and your stock drops the moment it’s recorded.
If typing is slow, point the camera at the barcode and Mayloo pulls the product up. Fewer taps, fewer wrong entries, a shorter queue.
The quiet win here isn’t speed for its own sake. It’s that when recording a sale is this easy, it actually gets done — every time, by everyone. And a sale that gets recorded is a sale that can’t go missing from your books.
See what you kept, not just what you sold
Selling NGN200,000 in a week feels good. What you kept after cost, after spillage, after the products you sold below the margin you thought you had — that’s the number that pays your rent.
Mayloo shows you profit per product, per category, and per payment channel, right on your phone. So you find out that the bottle everyone reaches for keeps 8 kobo on the Naira since your supplier’s last price rise, while the quiet product on shelf three keeps 40. That changes what you restock on Monday. If the gap between revenue and profit still trips you up, we broke it down in why revenue is not profit and cash flow versus profit.
Know before you run out, before it expires
The most expensive shelf in your shop is the empty one, because a customer who can’t buy from you buys two stalls down — and that lost sale never shows up anywhere. Mayloo watches your stock levels and tells you before a product runs low: “Shea Butter is below reorder point. 1.8kg left across 2 batches.” You restock what moves and stop tying up cash in what doesn’t.
If you sell anything with a shelf life — oils, butters, actives, food, medicine — the app also tracks batches and expiry dates and warns you while the stock still has value. Expired stock is the loss nobody records until they pull a dead batch from the back. That matters most for pharmacies and cosmetics shops, and we go deeper on it in tracking expiry dates.
Built to keep working when the network doesn’t
Patchy signal is normal here, not an exception, so Mayloo treats it as normal. You can keep recording sales on a slow or dropped connection, and the app catches up and syncs when you’re back online. NEPA taking light or a cell tower going quiet doesn’t stop you from serving the customer in front of you.
Send a real receipt straight to WhatsApp
A clean receipt does two jobs: it makes you look like a serious business, and it leaves a record you can check later. Mayloo turns any sale into a proper receipt or invoice and sends it to the app your customer already opens fifty times a day. No printer, no paper, no scribbling on a scrap. There’s more on this in professional receipts for a Nigerian business.
Run every branch from one screen
If you’ve grown past one shop, the Android app shows you every location’s stock and sales in one place, and lets you lock staff to their own branch so the numbers stay clean. You can see which shop is actually carrying the business and which one is quietly leaking, without driving across town to find out. We cover this in managing multiple shop locations and comparing branch performance.
Your numbers, locked to you
Your profit, your suppliers, your customer balances — that’s private. A PIN and fingerprint lock keep Mayloo closed to everyone but you, and the screen stays hidden even when you flick between apps. The person who picks up your phone sees a lock, not your books.
What all of this actually buys you
Strip away the feature names and here’s what changes on the ground.
You stop losing money you can’t see. Stock that walks out without a receipt, profit you couldn’t calculate, sales with no paper trail — those are three quiet leaks in most small shops, and Mayloo closes all three. The gap between what you thought you had and what you actually have closes with them, and that gap was costing you real Naira every week.
You make decisions on facts instead of feelings. “Good morning, Adaeze. 4 sales recorded yesterday. NGN87,400 in revenue, NGN31,200 profit.” That’s a shop you can steer — reorder what moves, drop what doesn’t, price with your real margins in front of you instead of a hopeful guess.
Your staff move faster and mess up less, because a tool that records a sale in half a minute with no maths is quicker than a notebook and harder to get wrong than a spreadsheet. And when it’s time to face your accountant or FIRS, you hand over a clean record instead of a nylon bag of receipts.
A woman selling shea butter from one shop deserves the same quality of stock and profit maths as a chain with 500 stores. Putting that on a NGN60,000 Android phone, in Naira, is the entire reason Mayloo exists.
Getting set up takes about 15 minutes
- Get Mayloo on your Android phone and create your account.
- Add the products you sell — set how you buy them and how you sell them, and Mayloo handles the conversions.
- Start recording sales. Stock updates and profit costs itself from the very first one.
No manual, no consultant, no accounting degree. And you don’t have to copy years of old records to begin — the app needs what’s on your shelf now, not your entire past. If the move still feels daunting, here’s a calm walkthrough of going from notebook to app without losing anything.
Try it free for 50 products
Mayloo is free for your first 50 products during early access — 50 products to record real sales, watch your true profit, and decide for yourself whether it earns a spot on your phone. No commitment to start. If it doesn’t help you run a tighter, more profitable shop, you’ve lost nothing but the notebook.
