Logic Invoice Community

config.php file has to be created at the root directory where logic invoice is installed (the directory where you should see the admin, application, system folder etc)

You can also give write permission to the directory, and re-run the installation.

not at the moment, it isn't a functionality built in.

I believe you will need to work backwards, where you will set all the item price 18% less, so the tax is calculated correctly at the final stage.

Admin >> Accounting >> Taxes. You can add multiple tax rates to a single tax class.

Invoice and opencart IDs wouldn't be in sync, but if you wish to, you can adjust the auto increment count in the logic invoice database.

It is meant to be that way as invoice number may not be equivalent to an order number. If you wish to keep both IDs in sync, you will need to adjust the database column to change the auto increment count.

You need to create your own language file translation.

if your language file changes the language direction accordingly.

Hello,

Great to have you on board.

1. Clients can login from the front end and view past invoices and current invoices
2. Yes, PayPal is supported

You will need to engage other companies to work on a support ticket system etc if you wish to extend Logic Invoice further.

You can make use of the journal entries
