 % whmcs-calc-deferred-revenue [options]


Deferring revenue is the process of recognizing revenue as you earn it, in contrast to as you receive the cash. This is the principle of accrual accounting, as opposed to cash-based accounting.

For example, suppose on Nov 1, 2019 you receive an amount of $12 for 12 months of hosting (up until Oct 31, 2020). In cash-based accounting, you immediately recognize the $12 as revenue on Nov 1, 2019. In accrual accounting, you recognize $1 revenue for each month you are performing the hosting obligation, for 12 times, from Nov 2019 to Oct 2020.

As another example, suppose you have three invoices:

 invoice num    type                  amount    note
 -----------    ------                ------    ----
 1001           domain registration     10.5, from 2019-11-11 to 2020-11-10
 1002           hosting                  9.0, from 2019-11-11 to 2020-02-10 (3 months)
 1003           hosting                 12.0, from 2019-11-01 to 2020-04-30 (6 months)

The first invoice is not deferred, since we have earned (or performed the obligation of domain registration) immediately. The second and third invoices are deferred. This is how the deferment will go:

 invoice \ period   2019-11   2019-12   2020-01   2020-02   2020-03   2020-04
 ----------------   -------   -------   -------   -------   -------   -------
 1001                  10.5
 1002                   3.0       3.0       3.0
 1003                   2.0       2.0       2.0       2.0       2.0       2.0
 TOTAL                 15.5       5.0       5.0       2.0       2.0       2.0

This utility collects invoice items from paid invoices, filters eligible ones, then defers the revenue to separate months for items that should be deferred (determined using some heuristic and additionally configurable options), and finally sums the amounts to calculate total monthly deferred revenues.

This utility can also be instructed (via setting the full option to true) to output the full CSV report (each items with their categorizations and deferred revenues).

Recognizes English and Indonesian description text.

Categorization heuristics:

  • Fund deposits are not recognized as revenues.

  • Hosting revenues are deferred, but when the description indicates starting and ending dates and the dates are not too old.

  • Domain and addon revenues are not deferred, they are recognized immediately.

  • Other items will be assumed as immediate revenues.

Extra rules (applied first) can be specified via the extra_rules option.

To use this utility, install the Perl CPAN distribution App::WHMCSUtils. Then, create a configuration file ~/whmcs-calc-deferred-revenue.conf containing something like:


db_host defaults to localhost. db_user and db_pass can be omitted if you have /etc/my.cnf or ~/.my.cnf. This utility can search for username/password from those files.

You can also add other configuration like extra_rules, e.g.:

 extra_rules=[{"type": "^$", "description": "^(?^i)sewa\\b.*ruang", "category": "rent"}]

You can then run the utility for the desired, e.g.:

 % whmcs-calc-deferred-revenue --date-start 2013-01-01 --date-end 2017-10-31 \
     --date-old-limit 2013-01-01 --full --output-file ~/output.csv

Wait for a while and check the output at ~/output.csv.


* marks required options.

Main options


Set what date will be considered too old to recognize item as revenue.

Default is 2008-01-01.


Default value:


Default value:


Configuration options

--config-path=s, -c

Set path to configuration file.

--config-profile=s, -P

Set configuration profile to use.

--no-config, -C

Do not use any configuration file.

Environment options


Do not read environment for default options.

Filtering options


End at this date (based on invoice payment date).


Start from this date (based on invoice payment date).

Logging options


Shortcut for --log-level=debug.


Set log level.


Shortcut for --log-level=error.


Shortcut for --log-level=trace.


Shortcut for --log-level=info.

Output options


Choose output format, e.g. json, text.

Default value:


Set output format to json.


When outputing as JSON, strip result envelope.

Default value:


By default, when outputing as JSON, the full enveloped result is returned, e.g.:


The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:


Rule options


See --extra-rules.


Example (in JSON):

            "type": "^$",
            "description": "^SEWA",
            "category": "rent"

Other options

--help, -h, -?

Display help message and exit.

--version, -v

Display program's version and exit.


This script has shell tab completion capability with support for several shells.


To activate bash completion for this script, put:

 complete -C whmcs-calc-deferred-revenue whmcs-calc-deferred-revenue

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.


To activate tcsh completion for this script, put:

 complete whmcs-calc-deferred-revenue 'p/*/`whmcs-calc-deferred-revenue`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.


This script can read configuration files. Configuration files are in the format of IOD, which is basically INI with some extra features.

By default, these names are searched for configuration filenames (can be changed using --config-path): ~/.config/whmcs-calc-deferred-revenue.conf, ~/whmcs-calc-deferred-revenue.conf, or /etc/whmcs-calc-deferred-revenue.conf.

All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME] or [SOMESECTION profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

You can also put configuration for multiple programs inside a single file, and use filter program=NAME in section names, e.g. [program=NAME ...] or [SOMESECTION program=NAME]. The section will then only be used when the reading program matches.

Finally, you can filter a section by environment variable using the filter env=CONDITION in section names. For example if you only want a section to be read if a certain environment variable is true: [env=SOMEVAR ...] or [SOMESECTION env=SOMEVAR ...]. If you only want a section to be read when the value of an environment variable has value equals something: [env=HOSTNAME=blink ...] or [SOMESECTION env=HOSTNAME=blink ...]. If you only want a section to be read when the value of an environment variable does not equal something: [env=HOSTNAME!=blink ...] or [SOMESECTION env=HOSTNAME!=blink ...]. If you only want a section to be read when an environment variable contains something: [env=HOSTNAME*=server ...] or [SOMESECTION env=HOSTNAME*=server ...]. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.

List of available configuration parameters:

 date_end (see --date-end)
 date_old_limit (see --date-old-limit)
 date_start (see --date-start)
 db_host (see --db-host)
 db_name (see --db-name)
 db_pass (see --db-pass)
 db_port (see --db-port)
