M4 Customer Invoice is dedicated to the final User of M4, who has to pay for made Calls. Admin can see and manage them in ACCOUNTING –> Customer Invoices, User can reach the list of his Invoices and check them from the main menu. Despite your settings, all values in Invoices are rounded into two digits after the comma.

Invoices are generated automatically according to the User's Billing Period (weekly, bi-weekly, or monthly).

Invoices List

Invoices can be viewed, created (WIP), or exported to either XLSX or PDF file in ACCOUNTING –> Customer Invoices. In the main window, you can see a list of all the Invoices.

All Prices are displayed in particular Invoice Currency. That means that in each line of the Invoice Price and Price with TAX will be shown in the currency which is written in the Currency column. The Currency column tells which currency the Invoice was generated with. Also, the exchange rate at the invoice generation moment is saved in the database so it may differ from the up-to-date exchange rate.
Total Price and Price with TAX are calculated into viewing Currency, which you can choose in the upper corner of the page. In the Total price calculation, there are used saved exchange Rate of each Invoice.


The default system Currency is the USD
Invoice A is generated on price = 100 in currency EUR with an exchange rate of 0.5
Invoice B is generated on price = 100 in currency DZD with an exchange rate of 0.25
Invoice C is generated on price = 100 in currency ALL with an exchange rate of 0.75

But now exchange rates are different: EUR - 0.75, DZD - 0.5, and ALL - 1.0.

If you want to see the Total price(sum of these 3 Invoices) in EUR. For Invoice B and C will be set exchange rate of today, but for invoice, 'A' exchange rate will be from the day when invoice was generated (0.5).

Same calculations with other currencies
If you want to see the Total price in DZD. For the Invoice 'A' and 'C' will be set exchange rate of today, but for invoice 'B' exchange rate will be from that day when the invoice was generated (0.25).
If you want to see the Total price in ALL. For the Invoice 'A' and 'B' will be set exchange rate of today, but for invoice 'C' exchange rate will be from that day when the invoice was generated (0.75).

The total price will be 733.3333 USD, or 500 EUR, or 266.6667 DZD, or 700 ALL

XLSX Invoices

XLSX file to export an Invoice is made from your own XLSX format template and information from the Invoices main window.

Global XLSX template

Create an XLSX file. The template you can prepare as you wish, you can fill it with information about the company, draw tables with column names, describe information taken from the Invoice main window, and so on. Template have to be uploaded in MAINTENANCE -> Settings, INVOICES setting Default XSLX Template

  • Check New XLSX template apply for old Invoices if you want to change the XLSX template for Invoices which is already generated.
  • Example of XLSX Invoice can be downloaded here.

Configuration for Dynamic information

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. How and what information is displayed can be set same MAINTENANCE -> Settings page. Just need to define the cell address in the correct format.

For example "A2", "B15", "AA9"


NOTE: If you do not want to use a particular dynamic value just leave empty input for it.

XLSX template For Users

By default system, global (default) template is used for all users. It is possible to enable specific templates for different users. This can be done by clicking on Excel Icon in the User's edit window.

XLSX invoice files without Currency names

In some cases when you want to add additional mathematical formulas in the XLSX file, you will need invoice prices without Currency names. In this case, you should use the setting Do not show currencies in XLSX Invoices in MAINTENANCE -> Settings.

Converting to PDF format

It is possible to convert the XLSX invoice to PDF format using the following methods:

  • By clicking on DOWNLOAD PDF on the Invoice Details page.
  • If Send XLSX Invoices converted to PDF option is enabled, sending invoices over email will convert XLSX files to PDF.
  • If the downloaded PDF invoice is wrong, it means that the XLSX template file probably is corrupted. Solution: Upload the XLSX template to Google Docs, open it in Google Sheets and download it as XLSX. After that upload this file into M4.

Invoice items are not grouped by Destination Group/Rate

Sometimes when the invoice is generated and options Group by Destination Groups and Show Rates is enabled, it can look that some destination groups are not combined. And it is not clear why they are not grouped as in the example below:

However, when the decimal number is increased to 10 at Maintenance - Settings - Visual, we can see that rate for one group is different. This is the answer to why two lines were not grouped:
