The problem

Why it exists.

Small sellers constantly need the same tiny tools, a chat link, a QR code, an invoice, a fee estimate, and end up paying for bloated apps or doing it by hand. WhatBiz Tools gives each one away free, instantly, and doubles as a friendly on-ramp into the wider WhatBiz platform.

WhatBiz Tools is a small suite of free web utilities for small businesses: generate a click-to-chat WhatsApp (wa.me) link with a pre-filled message, turn it into a scannable QR code for flyers and packaging, build and download a clean invoice, and work out exactly what Paystack's fee will be on any amount. Everything runs in the browser with no sign-up.

What's inside

Every surface, shipped.

01

WhatsApp link generator

Create a wa.me click-to-chat link for any number with a pre-filled message, so a tap opens WhatsApp straight into the conversation.

02

QR code generator

Turn the chat link (or any URL) into a clean, downloadable QR code for flyers, packaging, receipts and shop signage.

03

Invoice generator

Fill in items and totals and download a tidy, professional invoice, no spreadsheet gymnastics.

04

Paystack fee calculator

Enter an amount and see the exact Paystack fee and what settles, including the 1.5% + NGN 100 rule, waivers and the cap.

Hard decisions

The calls that mattered.

01

No login, ever

problem · Even a tiny sign-up wall kills usage for one-off utilities.

call · Every tool runs client-side with zero account and zero data stored, so it loads instantly and just works, which is also what makes it a friendly first taste of WhatBiz.

02

One small tool per job

problem · Bundling everything into one screen makes each tool worse.

call · Each utility is its own focused page, fast to load and easy to share a direct link to.
