Let the buyer finish the deal online
The slowest part of many deals is the PDF ping-pong.
With QTCFolio the buyer gets a secure link, picks their options, asks for changes and accepts online. The final quote PDF is created when they accept.
The longer version
Every emailed PDF revision restarts the clock. The seller edits the quote, regenerates the document, sends it, and waits.
A QTCFolio buyer link gives the customer controlled choices. They can change permitted quantities or add options, and pricing recalculates as they go. Which choices they can change, and whether a change needs approval, is set by your configured commercial process.
When the buyer accepts, the final quote PDF is generated from the accepted record, so the document matches what they agreed to.
