Typical turn around time for a design solution is of minimum 5-10 days*; Depending on the accuracy of the brief, volume of work and complexity.
We recommend providing the brief, at least 2 weeks in advance for a well thought and executed output.
Also keep all followups and changes on record and channeled only via Email.
To avoid confusion we would also recommend to adopt ONE SOURCE REVERT System, where only one person sends a Productive revert on any changes, suggestions or approvals after getting confirmation from all other senior members on client side decision making panel. We still would love to get everyone's individual feedback; yet one final Productive revert from One source is the best way to go ahead.
Sending files via Whatsapp reduces the quality of the file drastically, hence is strongly recommended to avoid doing so.
