I'm eager to assist you with your POS web application tasks. With proficiency in working with .xls format Excel files, experience in web application development, and a strong understanding of POS systems, I'm confident in meeting your specific requirements.
I'll ensure the seamless upload of the Excel file, insertion of the date column in sales, and enable the functionality to send invoices to email, adhering to your layout preferences.
If you could provide more details or access to the existing system, I can get started promptly. Looking forward to collaborating with you to complete this project efficiently.
Best regards,
Komal
