Free tools for running a Nigerian business
Invoices, receipts, VAT, withholding tax and margins. No account, nothing sent to us, and every one of them works on a phone.
“I need to send someone a bill”
Fill it in, watch it build, download a proper PDF. Naira and VAT at 7.5%, no account needed.
Invoice generator“They have paid — what do I give them?”
A receipt that proves it, including the balance still owing if they only paid part.
Receipt generator“What should my invoice even have on it?”
Worked examples for tailors, caterers, photographers, traders and mechanics — with the lines each trade forgets to charge for.
Invoice templates by trade“How much VAT is in this price?”
Both directions at 7.5% — the VAT inside a price, or the VAT added on top. They are not the same number.
VAT calculator“They are deducting something from my invoice”
What WHT comes off, what lands in your account, and why the deduction is not money you have lost.
Withholding tax calculator“Am I actually making money on this?”
Margin, markup, and the price to charge for the margin you want. Most traders mix the first two up.
Profit margin calculator
About these free tools
- Are these tools really free?
- Yes. No account, no card, no limit on how many invoices or receipts you make. They run in your browser, and nothing you type is sent to us.
- Do I need a WadMaster account to use them?
- No. Every tool here works without signing up. An account is for the part these tools cannot do — keeping a record of what you sent, who has paid, and what is still outstanding.
- Is my customer data safe?
- Nothing you type into these tools leaves your device. The invoice and receipt generators save a draft in your own browser so you do not lose your work, and that draft never reaches our servers.
- Can I use them on my phone?
- Yes, all of them. They are built for a phone on mobile data first, because that is how most Nigerian small businesses work.
- What is the difference between the tools and WadMaster itself?
- A tool answers one question once. The product remembers — every invoice you have sent, what has been paid against it, what your stock cost you and what you actually made. The tools are genuinely useful on their own; the product is for when doing it once a week stops being enough.
A tool answers one question. A record answers the year.
WadMaster keeps every invoice you send, what has been paid against it, and what your stock actually cost you — so the numbers are there when you need them.
