Put away the exercise book
OsemFlow is a simple app for recording your sales on your phone, tablet or computer. It keeps track of your stock and your customers' debts by itself, so you always know what you sold, what's left and who owes you.
Free plan with no time limit. No card needed.

How it works
Up and running in four steps
-
Create a free account
Sign up with your email or your Google account. It takes about a minute, and no card is needed.
-
Add what you sell
Scan a product's barcode or type its name, then add your price and how many you have. Start with your best sellers and add the rest as you go.
-
Sell as you normally do
Scan or search for the item, then take cash, transfer or both. For customers who pay later, give them an invoice instead.
-
Let it keep count
Every sale comes off your stock and adds to today's sales, with nobody counting or adding up. OsemFlow tells you what's running low and shows who owes you.
All you need is a phone, tablet or computer with internet. A barcode scanner is optional, because your phone's camera works too. You can also install OsemFlow like any other app.

What it does for you
The everyday problems it takes care of
Always know what's in stock
You hear "it's finished" at the time of sale.
Every sale takes the item off your count and every delivery adds to it. You're warned when something is running low.
Know who owes you, and how much
Customers buy on credit, and nobody agrees on the figure.
Give goods on credit with an invoice. OsemFlow keeps each customer's balance, clears their oldest debt first when they pay, and flags anyone who is late.
Trust what happens at your counter
Someone else is selling, and you can't be sure what went out.
Each staff member has their own login. Nobody can change a price at the counter, every sale shows who made it, and each shift ends with a summary of cash, transfers and other payments.
Stop goods expiring on the shelf
You find expired stock during a count, when it's too late.
Add expiry dates when goods arrive. OsemFlow keeps each batch separate, counts sales against the one that expires first, and warns you before anything goes out of date.
See how the business is really doing
Busy every day, but no clear picture of the month.
See today's sales when you open it, plus reports on sales, stock value, purchases, staff and late payers. Print or download any of them.
Give proper receipts and invoices
Customers ask for a receipt and you write one by hand.
Print a receipt for every sale, and download invoices as PDF to share on WhatsApp or by email, with your logo at the top.

Questions people ask first
Do I need a computer?
No. OsemFlow works in the browser on a phone, tablet or computer, and you can install it on your phone like any other app.
Does it work without internet?
No. It needs a connection to record a sale. That's what keeps every phone and till showing the same stock count.
Is it hard to learn?
Staff who sell open straight onto the selling screen: scan or search, take payment, done. If you get stuck, call or email us on weekdays.
Is the free plan really free?
Yes. No time limit and no card. If you need more than it allows, OsemFlow tells you, and you decide whether to upgrade.
Is my business information safe?
Your records are backed up continuously, and we practise restoring them every three months. OsemFlow staff cannot open your sales, products or customer records.
