Excel Invoice Template for Bulgaria: Free Guide

Creating invoices in Excel is one of the most common business practices in Bulgaria. Whether you're a freelancer, small business owner, or accounting manager, having the right invoice template saves time and ensures compliance with Bulgarian tax regulations.

But there's a critical distinction many business owners miss: there's a difference between creating invoices (which you issue to your customers) and processing invoices (extracting data from supplier invoices for accounting purposes). This guide covers both, but we'll focus especially on why you might want to rethink how you handle incoming supplier invoices.

Required Fields in Bulgarian Invoices

According to Bulgarian tax law and VAT requirements, every invoice must include these essential elements:

• Business name and registered address
• EIK (Единен идентификационен код—Unified Identification Code)
• VAT number (if registered for VAT)
• Phone and email contact information
• Bank account details (optional but recommended)

• Customer name and address
• Customer EIK or personal ID number
• Customer VAT number (if applicable)

• Invoice number (sequential)
• Invoice date (DD.MM.YYYY format in Bulgaria)
• Delivery date (if different from invoice date)
• Payment due date
• Payment method

• Description of goods or services
• Quantity and unit of measurement
• Unit price (price per unit)
• Line total (before VAT)
• VAT rate applied (typically 20% in Bulgaria, with some exceptions at 9%)
• Line total with VAT

• Total amount before VAT (taxable base)
• VAT amount
• Total amount due (including VAT)
• Currency (typically BGN for Bulgarian invoices)

• Reason for any VAT exemptions (if applicable)
• Reference to supporting documents
• Notes or payment instructions
• Signature or stamp (for original documents, may not be applicable for digital invoices)

Creating an Excel Invoice Template: Step-by-Step

Here's how to build a functional invoice template in Excel:

1. Set Up the Header

Start with a professional header containing:

• Your company logo (optional)
• Your company name in large text
• The word "INVOICE" (or "ФАКТУРА" in Bulgarian)
• A clear, easy-to-read layout

2. Company Information Section

Create a table or text box with:

• Your business name
• Address
• EIK: [Your EIK]
• VAT number: [Your VAT]
• Phone: [Your phone]
• Email: [Your email]
• Bank: [Your bank]
• IBAN: [Your IBAN]

3. Customer Information Section

Similar layout to the company section, but leaving spaces for customer details to be filled in:

• Customer name: _________
• Address: _________
• EIK/ID: _________
• VAT number: _________

4. Invoice Details Section

A row or two showing:

• Invoice Number: _________
• Invoice Date: _________
• Due Date: _________
• Payment Method: _________

5. Line Items Table

Create a table with columns:

6. Summary Section

A clearly separated area showing:

• Subtotal (before VAT): [formula sum]
• VAT 20% (or applicable rate): [formula calculation]
• TOTAL DUE: [formula sum]

7. Payment Instructions

Include:

• Bank transfer details (bank name, IBAN)
• Payment deadline
• Late payment terms (if applicable)
• Contact for payment inquiries

Common Mistakes When Creating Invoice Templates

The Problem with Invoice Templates

Now here's an important point: while having a solid template for issuing invoices is essential, many businesses are creating the same templates over and over to receive invoices. This is where most of the wasted effort lies.

If you receive 100 invoices per month from suppliers, you don't need 100 templates. You need a way to extract data from incoming invoices and organize it for accounting. This is fundamentally different from creating invoices from scratch.

From Invoice Templates to Data Extraction

Instead of manually recreating invoices or retyping data from supplier invoices into a template, consider a more efficient approach:

The second approach eliminates the need to maintain templates while significantly reducing errors and processing time.

When Templates Make Sense

Creating your own invoice template is still necessary if you:

• Issue many invoices to customers
• Need a branded template matching your company identity
• Want full control over invoice design
• Operate a professional services business where invoice appearance matters

Download or build a template using the structure outlined above, and customize it with your branding.

When Extraction Makes More Sense

Using an extraction tool like NeuralParse makes more sense if you:

• Receive numerous invoices from various suppliers
• Deal with inconsistent invoice formats
• Struggle with data entry errors
• Need to process invoices quickly for payment or accounting
• Want to automate data flow to accounting software

For these scenarios, NeuralParse's data extraction capabilities handle the hard work automatically.

Practical Tip: Hybrid Approach

Many successful businesses use both:

This combination gives you the best of both worlds—professional outbound invoices and efficient inbound invoice processing.
