Invoice essentials

Create a clear invoice without unnecessary complexity.

What an invoice is

An invoice records what was supplied, who is billing whom, the amounts due, and when payment is expected. Local requirements can vary.

What to include

Add supplier and client details, a unique invoice number, dates, item descriptions, quantities, prices, taxes, discounts, totals, and payment instructions where relevant.

Issue date and due date

The issue date records when the invoice was created. The due date communicates when payment is expected; payment terms can explain the agreed timing.

Subtotal, tax, and total

Subtotal is the item value before discounts and tax. Discounts reduce the taxable item value here; tax is then added to produce the total.

Private by design

Editing, calculations, logo handling, preview rendering, printing, and PDF creation happen in your browser. CoreBase does not receive or remotely store invoice data.

Questions

Practical invoice questions

Is this invoice legally valid everywhere?

Invoice requirements differ by country, industry, tax status, and transaction. Check the rules that apply to your business.

Where is my invoice data stored?

It is kept only in the current browser page while you work. CoreBase does not upload or remotely save it.

How is tax calculated?

Tax is calculated per item after that item’s percentage discount. Confirm that this treatment matches your local accounting requirements.

Can I add a logo?

Yes. The selected image is read locally and appears in the preview and generated PDF; it is not uploaded to CoreBase.

Methodology

Calculation and privacy details

Each line subtotal equals quantity multiplied by unit price. The line discount is deducted, then the line tax rate is applied. Totals aggregate all lines. PDF rendering runs locally from the same invoice state shown in the preview.
