WhatsApp Link Generator

Creates a direct wa.me link for a WhatsApp Business number. Business owners share this link on Instagram bios, Facebook pages, websites, or flyers so customers can start a conversation with one click. The link can include a pre-filled message. Designed for Nigerian businesses that rely on WhatsApp as their primary sales channel. Country code defaults to +234.

WhatsApp QR Code Generator

Converts a WhatsApp Business number into a scannable QR code image. Nigerian business owners print this on business cards, packaging, flyers, and banners. Customers scan with their phone camera and land directly in a WhatsApp chat. Download as a 280x280px PNG. Colour options: green, black, or white.

QR Code Generator with Logo

Creates static QR codes for any website URL, app store link, email address, phone number, or plain text. Users can upload their logo to the centre of the code and customise foreground and background colours. Uses high error-correction so the code scans reliably with a logo. The QR codes never expire because the link is encoded directly into the image. Download as PNG up to 2048px for print.

Invoice Generator for Nigerian Businesses

Generates professional PDF invoices with business name, client details, itemised line items, optional VAT (defaulting to 7.5% as required by FIRS for registered businesses), and a customisable brand colour. Invoices download via the browser print dialog. Currency defaults to NGN. No account needed.

Paystack Fee Calculator Nigeria

Calculates Paystack transaction fees for any NGN amount using the current fee structure: 1.5% of the transaction, plus NGN 100 for transactions above NGN 2,500, capped at NGN 2,000. Shows both the amount the merchant receives and the amount to charge the customer if passing the fee on. Includes a reference table of common amounts and their Paystack charges.

Nigerian Business Name Generator

Uses AI (Groq LLaMA 3.3) to generate 10 unique business name ideas for any Nigerian business type. Names include English options, names incorporating Yoruba, Igbo, or Hausa words, and a mix of modern startup-style and traditional names. Each name comes with a tagline and an explanation. Free, no sign-up required.

WhatsApp Receipt Generator

Creates formatted payment receipts that business owners can share on WhatsApp. Supports many payment methods including Bank Transfer, card, Cash, POS, and mobile money. Downloads as a clean PNG image and also produces a plain-text version formatted for pasting into WhatsApp. Works with multiple currencies and lets you add your own footer with no watermark.

Profit Margin Calculator

Calculates profit margin, markup percentage, and break-even point for product-based and service businesses. Three modes: Profit Margin (profit, margin %, and markup % from cost and selling price), Markup Calculator (selling price and margin from cost and desired markup), and Break-Even (monthly units needed to cover fixed and variable costs). Works in any currency.

CAC Business Name Check Guide

Provides a step-by-step guide for checking business name availability on the Corporate Affairs Commission (CAC) portal at pre.cac.gov.ng. Includes CAC name rules, approximate registration fees (Business Name: NGN 10,000-15,000, Limited Liability Company: NGN 15,000-30,000), and direct links to the official CAC pre-registration portal.
