Creating Invoices One by One Is Costing You Hours
If you bill more than 10 clients per month, manual invoicing is eating your productive time. Here's the math:
Manual: One at a Time
- - 5 minutes per invoice (data entry, formatting, review)
- - 100 invoices = 8+ hours of work
- - Copy-paste errors on client details
- - Inconsistent formatting between invoices
- - Sending each invoice email individually
~8 hours for 100 invoices
Batch: CSV Upload
- Export data from your system to CSV
- Upload one file, generate all invoices
- Zero data entry errors
- Consistent professional formatting
- Download as ZIP or email all at once
~5 minutes for 100 invoices
How Batch Invoice Generation Works
Four steps from spreadsheet to sent invoices
Prepare Your CSV
Download our template or use your own spreadsheet. Columns: client name, email, description, quantity, rate, due date.
Upload & Validate
Drag and drop your CSV. InvoiceKits validates every row and flags any issues before generating.
Choose Template
Select from 5 professional PDF templates. Your company logo and branding are applied to every invoice.
Download or Send
Download all PDFs as a ZIP file, or email each invoice directly to the client with a personalized message.
Simple CSV Format
If you can use a spreadsheet, you can use batch invoicing. The CSV format is straightforward:
- Required columns: client_name, client_email, item_description, quantity, unit_price
- Optional columns: tax_rate, due_date, currency, notes, invoice_name
- Multiple line items: Add multiple rows with the same client to create multi-line invoices
- Multi-currency: Set a different currency per invoice row

Frequently Asked Questions
How many invoices can I create at once with batch upload?
There is no hard limit on the number of invoices per CSV upload. Professional plan users regularly generate 100-500 invoices in a single batch. The system processes them in seconds.
What CSV format does the batch invoice generator accept?
The CSV file needs columns for client name, client email, item description, quantity, unit price, tax rate (optional), due date, and currency. You can download a pre-formatted template with all the correct column headers.
Can I use different templates for batch invoices?
Yes. When you upload your CSV, you select which of the 5 professional PDF templates to use. All invoices in the batch will use the same template, styled with your company logo and branding.
Do batch invoices support multiple currencies?
Yes. Each row in your CSV can specify a different currency code (USD, EUR, GBP, etc.). The batch generator formats amounts according to the specified currency.
How is batch invoicing different from recurring invoices?
Batch invoicing creates many different invoices at once from a CSV file -- ideal for billing multiple clients for different amounts. Recurring invoices automatically generate the same invoice on a schedule (weekly, monthly, etc.) for ongoing services. InvoiceKits supports both.
Which plan includes batch invoice upload?
Batch CSV upload is available on the Professional plan ($29/month) and Business plan ($79/month). Free and Starter users can create invoices individually or upgrade for batch processing.
