Just click on each point to expand.

Invoices

• Number start – how the invoice number should start.
• Number length – the length in digits AFTER Number Start – e.g. Number Start is not counted into this length. This value is active only for the first number type.
• Number type – select more appropriate number format. INV000001 means auto incremental number after "Number start" value. INV070601 means "Number start" + date + invoice max id.
• Duration format - time format in invoice. Available Options - 'H:M:S', 'H:M', 'M'. When option 'M' is used, the sub-option Decimal places appear, where you can select precision.
• Invoice Group By - when "Destination" is selected, an additional option appears, that allows selecting grouping by "Destination Name" or "Destination Group". "Destination Name" combines all destinations with the same name into one Invoice entry.
• Manual Payment Line - changes the name of line: Prepaid VoIP Services in the invoice. Available in Manual Payment invoices.

Consider the following before changing settings:

• if the Number type is changed from INV070601 to INV000001 AND the Number start is kept the same, the numbering continues from the last INV070601 format number.
• if the Number type is changed from INV070601 to INV000001 AND Number start is kept the same AND the Number length is set to some lower value than it is sufficient to fit the previous INV070601 numbering, then the Number length value will be disregarded and the lowest sufficient value to continue from last Invoice number will be used.
• if the Number type is changed from INV070601 to INV000001 AND Number start is kept the same AND the Number length is set to some higher value than it is sufficient to fit previous INV070601 numbering, then numbering will continue from the last INV070601 format number and new Number length will be applied, by placing additional zeros between Number start and last number (INV070601 > INV0000070602).

XLSX

XLSX file to export an Invoice is made from your own XLSX format template and information from the Invoices main window. An example of the template can be downloaded here.

When you already have a template for example with all data of your company, with drawn tables and so on, you need to define where should be shown the dynamic information of the invoice. To do that you just need to define the cell address in the correct format.

Client Address Cell is different than other ones - once you will define this, all other Address Related Cells will be filled automatically and will not be editable. Also, no empty space will be left if any Address sub-cell is not defined. For example, if Client State is not defined in User's Settings, then this Cell will not be empty in Invoice - all Address Cells below will go up by one Cell. This allows nice Address formatting without leaving spaces if some Address data is not defined in the User's settings.

• Comment - refers to the Comment available on the Invoice Details page. The Invoice needs to be recalculated after adding a comment, so that comment would be applied.

Emails

• Sending globally enabled – if this is checked, you will be able to use Mass Mailing and the system will send emails upon user registration.
• SMTP server – hostname of the server.
• Port – port of SMTP server.
• Login – username to your SMTP server.
• Password – password to your SMTP server.
• Batch size – value for Mass Mailing, or how many emails to send at once.
• From – email address to put into From: field in an email. Acceptable formats are example@email.com or John Smith <example@email.com>.
• Test email sending – save settings and press this to test email sending. Do not forget to save settings first!

P.S. Remember to set the admin's e-mail in the admin's personal settings. Without this test email sending will not work!
