Billing system needs to store, manage and edit all client information including addresses, payment information (credit card details), plan information, etc. Invoice generation (recurring as well as one-off invoices). Integration with payment processor.
System security is a priority!
Asterisk knowledge is a plus, as CDR calculation of calls may be required.
Previous experience designing billing systems is a plus. Please provide examples.
Project will be awarded to most experienced bidder with previous examples of such work.
Thank you for your bids and good luck!
