What is the difference between margin and markup?
Markup is measured against what you paid; margin is measured against what you sold for. Buy at ₦1,000 and sell at ₦1,500 and that is a 50% markup but a 33.3% margin — the same trade, two very different numbers, and quoting the wrong one is how a business thinks it is making more than it is. The free calculator at wadmaster.com/profit-margin-calculator converts between them. Inside WadMaster, recording a product's cost price means margin is worked out for you on every sale.

Yes. The invoice generator, receipt generator, VAT calculator, withholding tax calculator and profit margin calculator are all free with no account, no card, and no limit on how many documents you make. There is no trial that expires and nothing to cancel.
Do I need an account to use the free tools?
No. Every tool at wadmaster.com/tools works without signing up. An account is only for the part the tools cannot do: keeping a record of what you sent, seeing who has paid, and chasing what is still outstanding.
Is the free invoice or receipt PDF watermarked, and can I send it to a real customer?
There is no watermark and no WadMaster branding forced onto the document. The PDF carries your business name and details, so it is meant to be sent to a real customer exactly as it downloads.
