Create your first invoiceQuestions people actually ask
Is BusinessKit free?
Yes. Calculators and the invoice and quotation builders are free to use. A free account lets you save work. Paid plans are listed on the pricing page and are not required to try the tools.
Do I need an account to calculate GST or profit?
No. You can calculate immediately. Sign in only if you want to save a result or keep invoices in one place.
Is this a government GST portal?
No. BusinessKit is a private toolkit. It is not affiliated with the GST portal, any ministry, or any bank.
Can I use the invoices with customers?
Yes. The invoice is a real document you can print or save as PDF from your browser. Check the figures before you send it.
Does this replace an accountant?
No. The tools do arithmetic and keep records you create. They do not file returns, give tax advice, or connect to your bank.
