A printed slip is in the bin by evening. The same invoice sent to WhatsApp is still there at warranty time, at return time, and at the end of the year when somebody asks what they paid. This connects your billing software to your shop’s own WhatsApp Business number and sends it automatically, the moment the sale is billed.
This is a small problem that costs real money, and it costs it quietly.
A customer comes back four months later with a fault and no paperwork. Somebody spends twenty minutes in the day book. A wholesale buyer says he already paid; nobody can produce the bill without going to the office. A shop with a thousand customers has a thousand of these a year and never counts them, because each one is only twenty minutes.
The fix is not a better printer. It is putting the invoice somewhere the customer will still have it — and there is exactly one place in Pakistan where that is true of nearly everybody.
We will say the unhelpful thing first. If you write ten invoices a week, this is not worth wiring up and you should keep printing. This earns its keep in shops writing dozens a day, where the same twenty-minute search happens often enough that you have stopped noticing it.
You sign in with your own WhatsApp Business account and authorise our software to send on your behalf. It stays your account, registered to your business and your number. Nothing is transferred to us and you can revoke it whenever you like, which stops us sending immediately.
WhatsApp requires every automatic message to use a format it has approved in advance. We write those, submit them for approval on your account and deal with anything that comes back — so you never open WhatsApp’s own management tools.
When your staff save a sale in RetailWiz, BizMan or your own system, the invoice goes out to that customer’s WhatsApp with the PDF attached — no extra screen, no copying numbers into a phone. Sent, delivered, read, or failed and why is recorded against the invoice number, so a query takes seconds to answer instead of a trip to the filing cabinet.
The bill the customer just paid, sent to their WhatsApp as a PDF the moment it is saved. It carries your shop name, the invoice number, the date and the amount.
The quiet benefit is not the sending. It is that four months later the customer can find it themselves, and your counter staff never get asked.
For anyone selling on credit — wholesale, trade counters, anything with a ledger. A short, polite message a few days before a payment falls due, and another if it passes.
Most late payment is not refusal, it is forgetting. A reminder that arrives where the person actually reads things collects a surprising amount of it without anybody having an awkward phone call.
Order confirmed, ready for collection, out for delivery, delivered. The messages that otherwise arrive as five phone calls asking where something is.
The test we apply before building any of these: would you be glad to receive it yourself? If not, we do not send it, however easy it would be to.
WhatsApp charges for each automatic message. That is Meta’s charge, not ours — it is billed to your own account with them, at their published rate, and we never see the money. For a shop sending a few thousand invoices a month it is a small number, and you can check it yourself on Meta’s own pricing page before you commit to anything.
What you pay us is for the software and the setup: connecting your account, writing and maintaining the message formats, wiring it into your billing system, and keeping it running. We quote that as a flat monthly figure so it does not move with your busy months.
We do not mark up your messages, and we would be suspicious of anyone who offers to. Your account, your rate, your bill from Meta — you can always see exactly what the platform is charging you and compare it to the published price.
No. They need WhatsApp, which they already have. The message arrives in their normal chat list from your business, and they can reply to it like any other message.
Usually not. In most cases your existing shop number can be connected while your staff carry on replying to customers in the WhatsApp Business app on the phone, exactly as they do now. There are a few conditions — the app has to be reasonably up to date, and the switchover has to be completed in one sitting — and we check all of that with you before touching anything. Where it is not possible, a second number works fine.
You do, without qualification. You sign in with your own account and grant our software permission to send on your behalf. We never own it, never take the number, and cannot move it anywhere. Withdraw the permission in your own WhatsApp settings and we stop having any access at all, the same minute.
It lands with you, in the WhatsApp Business app your staff already answer. We are not a middleman sitting in your conversations — a reply to an invoice is just a customer messaging your shop.
Not if you send what we have described. WhatsApp draws a hard line between a message somebody expects — their own invoice, their own delivery, their own payment date — and marketing they did not ask for. The first is welcome and cheap; the second gets reported and gets numbers restricted. We build the first, we tell you honestly where the line is, and we will not help you cross it.
Often yes. If your existing system can call a web address when a sale is saved, or can be made to, it can be connected. If it genuinely cannot, that is worth knowing early and we will say so rather than sell you a project that ends in a workaround.
Connecting the account and getting the message formats approved is usually a matter of days. Wiring it into your billing system depends on which system it is — days for our own products, longer for somebody else’s.
That one number decides whether this is worth doing for you. If it is too few, we will tell you and you will have lost fifteen minutes.
