Sell it once, or a thousand times — same price
Your bill isn’t about how much you sell. It’s about how many differentproducts and customers you did business with — each one counted once for the month, however many times it came up. Everything that didn’t sell is free, and a month with no orders costs ₹0.
Four numbers, and that’s the lot
No feature is behind a paywall and no number is hidden in a contract. This is it.
A product counts once for the month if it was part of any order — whether it sold once or a thousand times.
An add-on that was sold alongside a product this month, counted once.
A bundle that sold this month, counted once however many went out.
A customer who ordered this month, counted once no matter how many orders they placed.
All prices in INR, exclusive of 18% GST. So ₹10 of usage shows as ₹11.80 on your invoice.
Selling more of a thing doesn’t cost you more
It’s the thought that stops people trying usage pricing: “if I sell more, I’ll be charged more.” You won’t. Here’s exactly how the counting works.
Your chai sells 800 times across the month — busiest thing on the menu.
It’s counted once. The 800 sales change nothing about what you pay.
A regular comes back and orders from you 15 separate times this month.
One active customer, counted once — loyalty doesn’t cost you extra.
60 different products sold, to 140 different customers, across all your orders.
That’s your subtotal for the month, plus 18% GST. Only the variety is counted.
So your bill grows when you sell a wider range of things to more different people — not when a busy day moves the same items again and again. Volume is free. Variety is what’s counted.
Put your own numbers in
Roughly what you sell in a busy month. The bill updates as you type.
These are rough monthly estimates — change any of them to match your own shop.
In a month, you sold…
Different items, not units. A product that sold 500 times is one product here.
Your usage this month
Plus 18% GST, added on your invoice.
Sold nothing this month? Then you owe nothing. That’s not a promotion — it’s just how the bill is built.
Most software charges you whether you sell or not
That’s the part that stings in a quiet month. It shouldn’t.
Desktop licences
Pay per device, per year
A fixed yearly licence for each computer — paid in advance, the same in your best month and your worst, and tied to one machine at the shop.
Subscription plans
Pay for a tier, not your usage
A monthly plan chosen in advance, with the features you actually need often locked behind the next tier up. Outgrow it and your price jumps.
BlackX
Pay once per active item
Every feature from day one. Each product and customer that was part of an order is counted once for the month — however many times it sold. A slow month costs almost nothing, and a month with no orders costs ₹0.
The bits people usually only find in the fine print
So you don’t find them later.
A payment method activates you
No money changes hands upfront, but you add a card, bank account or UPI mandate before you can sell — that’s what switches the account on.
The ₹1 that comes back
Setting up that mandate takes a ₹1 verification charge. It’s refunded to you automatically — it’s there to prove the method works, not to bill you.
Miss a bill? Your data’s still yours
You get 15 days. After that the account pauses until you clear it — but nothing is deleted, you can still read all of it, and it comes right back when you pay.
Pricing questions
If I sell more, do I pay more?
Not for selling the same things more often, no. Each product, add-on, bundle or customer is counted once for the month if it was part of any order — so a product that sold 500 times costs the same ₹10 as one that sold once, and a customer who ordered ten times still counts as one ₹1 customer. Your bill only grows when you sell a wider variety of things to more different people. Volume is free; variety is what's counted.
When am I billed?
At the end of each calendar month, once the month is complete. You're never charged in advance, and you only ever pay for the month that's just finished.
What does a slow month cost?
Only what sold. If a product or a customer wasn't part of any order that month, it isn't charged — and a month with no orders at all costs ₹0. There's no minimum bill and no floor.
Do I have to pay anything to start?
No setup fee and no advance payment. The only debit is a ₹1 charge used to verify your payment method, and it's refunded back to you automatically. You do need a payment method on file before you can start selling, though — that's what activates the account.
How do I pay my BlackX bill?
You add a payment method once — a recurring mandate through Razorpay, using a card, a bank account, or UPI — and your monthly invoice is charged against it. Every invoice, with the full usage summary behind it, sits in your dashboard for you to read and download as a PDF.
Are taxes included?
No — every price on this page is before GST. BlackX charges 18% GST on top, so ₹10 of usage appears as ₹11.80 on your invoice. If you're GST registered, your invoice carries our GSTIN and the full tax breakup, so you can claim it back.
Do credits reduce my bill?
Yes. Any credits on your account come off your monthly invoice before GST is worked out, so the tax is calculated on what's left rather than the full amount. One credit is worth ₹1.
What happens if I don't pay a bill?
You get 15 days. After that the account is restricted — you can't take new orders and your storefront goes offline until the invoice is cleared. Your data is never touched: everything stays where it is, you can still read all of it, and it all comes straight back the moment you settle up.
