Free billing software for linux

A lot of unsolicited email goes unreported because tracing the origins of a possibly forged mail and finding the right people to report to, is complicated and time-consuming. Ricochet, a smart net agent, automates this process.

Ricochet project traces the names and addresses of the systems where the spam originated from along with the servers that provide domain name resolution services to these systems (in most cases their ISPs). Then it collects/generates a list of email addresses of tech/billing/admin/abuse contacts of these system and mails them a complaint and a copy of the spam.

pmacct is a small set of passive network monitoring tools to measure, account and aggregate IPv4 and IPv6 traffic; aggregation revolves around the key concept of primitives (VLAN id, source and destination MAC addresses, hosts, networks, AS numbers, ports, IP protocol and ToS/DSCP field are supported) which may be arbitrarily combined to build custom aggregation methods; support for historical data breakdown, triggers and packet tagging, filtering and sampling.

Aggregates can be stored into memory tables, SQL databases (MySQL or PostgreSQL) or simply printed to stdout. Data is collected from the network either using libpcap (and optionally promiscuous mode) or reading NetFlow v1/v5/v7/v8/v9 and sFlow v2/v4/v5 datagrams, both unicast and multicast.

IP accounting is the key in ISP/IXP network operations like billing, graphing network resources usage, live or historical traffic analysis, handling of network thresholds, provisioning and SLA monitoring. SNMP counters sometime are not this useful because of their coarse granularity.

Finer granularities become valuable if data are historical and match logical entities of interest such as Autonomous System Numbers, departmental or customer network chunks, specific traffic flows, etc. Further, actual large-scale networks are able to produce, in very short times, high amounts of data that become quickly difficult to be processed in a meaningful way

In this context, traffic aggregation and advanced filtering and sampling capabilities are requirements that cannot be missed anymore.

Either using memory or SQL tables as backend storage, pmacct can easily feed data to tools like MRTG, RRDtool, Cacti and Gnuplot among the others. A little scripting abilities are required to glue pmacct with external tools and a number of sample scripts and some tutorials are already available.

Ultrize TimeSheet is a Web based time card to keep track of all time spent on multiple clients and projects.
Ultrize TimeSheet project can keep track of multiple clients with multiple rate quotes with multiple projects easily, intuitively, and simply.
I realized a while ago, that I was having a hard time keeping all my clients organized; multiple clients with multiple rate quotes with multiple projects all in order on a sheet of paper, billing and accouning was starting to become a nightmare. So I did what any proper Interneteer would do .. I created a simple easy to use web based solution for my paper mess.
The initial version was comprised of about 4 hours worth of work, and was by no means feature rich -- I made it to be easy to use, and easy to understand. Now it is full of excellent features that will help anybody who is looking for a great way to keep track of time and billing for multiple clients. I think you will find it is very useful at giving you a valid concept of how much money you are making with each client you service, and how much time you are spending on your projects.
Main features:
- GPL Licensing
- Unlimited number of Clients
- Unlimited number of Jobs
- Unlimited number of Tasks
- Unlimited number of Notes per Job
- Classes extendible via object oriented programming
- Written with Smarty Templates and PHP 4.3+ with MySQL

Beanie is a flexible, distributed accounting system for medium-sized companies.
It includes back-end batch processing as well as a GTK GUI and provides automated purchases, sales, and nominal ledgers as well as automated invoicing (via email).
Beanie project also supports payroll and VAT.
Installation:
STEP ONE:
You must create a user on the system called beanie. This unprivileged user will own all the accounting files and executables. The home directory of this user will be the main location for all accounting files so choose wisely. Examples are /v/beanie or
/var/accounts.
This is an example of the password entry:
beanie:*:101:20:The Accounting System:/v/beanie:/bin/csh
Make sure you set the BEANIEROOT environment variable in the file beanie.mk to the home directory of the beanie user.
STEP TWO:
You must create a MySQL database called beanie. You then need to create a user also called beanie with a 8 to 10 character password which has full access to this database. Check that you can access the new database using the following command:
% mysql -h -u beanie -p beanie
You will be prompted for a password. Enter the password you set on the account and youre now ready to create a config.h file.
STEP THREE:
Copy the file config.h.sample to config.h and edit it. You will find information on how to configure this file in the comment blocks of the file. Note that the MAIN_DBHOST and DBPWD_CHARxx values need to match what you entered above.
STEP FOUR:
Edit the file beanie.mk and make sure that the defaults are OK.
Once you have completed these steps, compile the source by running the following commands:
% make clean all
% make install
You may need to run the second make as root in order to have permissions to create directories and some binary files (such as xeparse which needs to be installed in /usr/libexec).
STEP FIVE:
You need to create a cron(8) entry for the beanie user. There is a sample cron entry in the file crontab.sample. Edit this file and change $BEANIEROOT to be the home directory of the beanie user. Then, either logged in as beanie or as root, run the following command:
% crontab -u beanie < crontab.sample
This makes sure the overnight processing is performed every evening at 11PM. Each day, the databases will be backed up and the daily operations (such as invoicing, etc) will be performed. Each Sunday, the end of week tasks will be performed and on the last day of the month, the monthly, quarterly and annual tasks will be performed.
You can examine these scripts to see what they do:
overnight/acct.prolog
overnight/acct.daily
overnight/acct.weekly
overnight/acct.monthly
overnight/acct.epilog
Edit the tmac source files for your specific information. The key one here is lhead.tmac because this is the source for your company letterhead. Its written in troff.
