Quick Answer

A proforma invoice is a preliminary bill of sale sent to a buyer before goods or services are delivered. It lists estimated prices, quantities, and terms, and is commonly used for advance payments, import/export customs clearance, or buyer confirmation before the final tax invoice is raised.

Common Challenges Businesses Face

Without the right tool, creating and tracking proforma invoices becomes a manual, error-prone process.

Inconsistent, Unbranded Formats

Sending proforma invoices as plain Word or Excel files looks unprofessional and often misses required fields like HSN codes or tax breakup.

No Tracking of Pending Conversions

Without a system, businesses lose track of which proforma invoices are awaiting approval, expired, or already converted into a sale.

Manual Re-Entry Causes Errors

Recreating the same invoice from scratch after customer approval leads to typos, mismatched totals, and delayed billing.
