Short answer: Up to 2,000 invoices per Excel file upload.
Each row in your Excel spreadsheet (excluding the header row) becomes one invoice. This makes bulk invoice generation from Excel practical for monthly billing cycles, quarterly reports, and annual reconciliation.
Batch Processing Limits
Our Excel to invoice generator processes:
- Maximum per batch: 2,000 invoices
- Processing time: 5-10 minutes for full batch
- File structure: First row = headers, remaining rows = invoices
- Output format: All invoices delivered as PDF files in a ZIP archive
What If I Have More Than 2,000 Invoices?
For larger datasets, split your Excel file into multiple batches:
- Split your Excel file into chunks of 2,000 rows or less
- Upload and process each batch sequentially
- System remembers your mapping so subsequent uploads are faster
- Combine the ZIP files if you need all invoices together
For example, 10,000 invoices would require 5 separate uploads, taking approximately 25-50 minutes total processing time.
Batch Size Best Practices
- Keep batches under 2,000 rows for optimal processing
- Include all necessary columns in each batch
- Maintain consistent column headers across batches
- System remembers your field mapping between batches
- Process large datasets during off-peak hours
How Long Does Processing Take?
Processing time depends on batch size:
- 1-100 invoices: 30 seconds to 1 minute
- 100-500 invoices: 1-3 minutes
- 500-1,000 invoices: 3-5 minutes
- 1,000-2,000 invoices: 5-10 minutes
This is dramatically faster than manual invoice creation, which could take days or weeks for the same volume.
Excel File Structure
Your Excel file should be structured as:
- Row 1: Column headers (Order ID, Customer Name, Amount, etc.)
- Row 2 onwards: One invoice per row
- All rows: Use consistent data format
The first row is used for column mapping, and every subsequent row generates one invoice.
Typical Use Cases
Common batch sizes by business type:
- Freelancers: 5-50 invoices per month
- Small businesses: 50-500 invoices per month
- SaaS companies: 500-2,000 invoices per month
- Marketplaces: 2,000+ invoices (multiple batches)
Splitting Large Excel Files
If you need to split a large Excel file:
- Keep the header row in each batch
- Copy 2,000 data rows (plus header) to a new sheet
- Save each batch as a separate Excel file
- Upload and process sequentially
Excel's built-in filtering and copy-paste functions make this straightforward.
