Quotation and estimate maker
Make a quotation in a minute, and turn it into a bill in one click.
Customers ask for a rate before they buy. MyInvoiceDB makes estimates (quotations) and proforma invoices from the same item list you bill from, so prices and GST match. When the customer says yes, convert the estimate into a sales invoice without typing it again.

02
From quotation to bill in one click
Open the estimate list, pick the one the customer accepted and choose Convert to Invoice. The items, rates and GST carry over to a new sales invoice. Proforma invoices convert the same way.
03
Quotation, proforma or invoice?
A quotation or estimate is an offer. A proforma invoice is a confirmed offer, often used to ask for an advance. A tax invoice is the real bill for a sale, and only the tax invoice counts in your GST sales.
04
Print or share
Save the estimate as PDF to print, email or share from your PC. It uses your business name, address and GSTIN from your invoice settings.

FAQ
Questions and answers
Is the quotation maker free?
Yes. Estimates, proforma invoices, delivery challans and invoices are all free. Only optional WhatsApp messages are paid, from a prepaid wallet.
Can I add GST to a quotation?
Yes. Each item carries its GST rate, and the estimate shows CGST + SGST or IGST the same way a bill does.
Do I need to retype the quotation as a bill?
No. Convert to Invoice copies the items and rates into a new sales invoice.
Is a proforma invoice valid for GST?
No. A proforma invoice is not a tax invoice and does not go into your GST return. Issue a tax invoice when the sale happens.
