Manager is the best accounting software I am aware to. But if its sales invoice can support POS invoicing, it will be best for me. How much it will be cost to me if I want Manager to be convert into POS based invoicing.
There is no customization available. Further, you shouldn’t be using sales invoices for point of sale transactions. Sales invoices are for credit sales to defined customers. See the Guide:
https://forum.manager.io/t/cash-sales-selling-without-sales-invoices/7321
Many retail users make a single summary entry at the end of each day rather than try to enter each transaction. Manager is not designed as a POS system.
To clarify the above - you shouldn’t be using sales invoices for point of sale “CASH” transactions.
You can have sale invoice - point of sale transactions where you have defined customers who attend the business and takes the goods with them for later payment.
This mostly occurs with trades (builders, electricians, plumbers etc.) who “drive thru” to buy goods from the supplier on a credit account.
If your business has a cash register, print out a end of day summary and use that as your input source
is it possible to have a printout of each entry i made in cash sale?
Yes, as long as each one is a separate Receive money transaction. Click View and then PDF or Print, depending on how you want to print it.
