Running a business in 2025 is increasingly moving online — and documentation is no exception. One of the most common questions among entrepreneurs and freelancers is how to quickly and correctly issue an invoice without involving accountants, dealing with paperwork, or registering on complex platforms.
While managing finances and sending invoices is becoming simpler, it’s just as important to have a reliable online presence to support your business. You can get the best hosting experience with our affordable VPS plans in Dubai
In this article, we’ll explain what an online invoice is, how to properly create one, how it differs from other documents, and — most importantly — how to send a free invoice in just 2 minutes using Site.pro, even if you’re not an accountant.
What Is an Online Invoice, Its Purpose, Differences, and Benefits
An invoice is a document in which the seller (or service provider) lists goods or services that need to be paid for by the buyer.
It is not a mandatory legal document but is widely used in business practice — especially as a preliminary basis for payment.
An online invoice is the same document, but created and sent via the internet. Its advantages include:
- No need to install software
- Accessible from any device
- Quick and easy to send to clients
- Convenient cloud or email storage
- Minimizes errors thanks to templates
| Document Type | Description | Required? |
| Invoice | A request for payment for goods or services | Yes, commonly used |
| Invoice-Contract | An invoice that also serves as a contract | Sometimes used |
| Tax Invoice | A formal accounting document for VAT reporting | Only under standard tax systems |

- For the client — so they know exactly how and what to pay
Rules for Filling Out an Invoice
An invoice should contain:
- Seller details (VAT number, bank account, address, etc.)
- Buyer details (if available)
- Invoice number and date
- List of goods/services, quantity, price, total amount
- Total sum, including VAT (or marked “VAT-exempt”)
- Payment method (bank transfer, etc.)
If you are self-employed or on a simplified tax system without VAT, a standard invoice is sufficient.
