Merchants' Village Consignment POS Software - Now Free and Open Source

What is This Free POS Software?

The Merchants' Village Consignment POS system is a completely free and open source (GPL3) software cash register system that can be used to process sales transactions at any type of retail store or other business.  It was also specifically designed to help consignment businesses sell items for others.  The system prints price labels for inventory items which consignors want to sell, and provides a cash register "point of sale" (POS) screen that can be easily used by consignment shops and mall/market/event operators to scan and sell large volumes of items quickly.

There are some screen shots, and a video which walks through the basic functions.


The system is the result of more than 2 decades of hardware/software system implementation for retail and consignment businesses, by Nick Antonaccio.  Versions of the system have been used, tested, and improved constantly, in several of the highest volume consignment environments in the country.  The current downloadable edition was used to sell millions of consigned items at the Merchants' Village location in Pittston, PA  USA, a 120,000 square foot (3 acre) retail center which serviced hundreds of full time commercial consignment vendors and tens of thousands of customers.  The result is one of the fastest, most reliable, and easiest to use, industrial strength consignment POS systems available anywhere.


A core purpose of the software is to provide sales reports, not only for the store/market owner, but also for individual consignors/vendors who sell products on consignment at the owner's business.  The consignment business operator can sell all consigned items at one centralized cash register checkout area, and sales are tracked by the software.  Vendors (consignors, sellers, booths, etc.) can check their individual sales at any time, using a simple password protected online form that can be accessed anywhere on the Internet.  Detailed reports of all sorts can also be printed directly from the software, such as daily cashier sales reports, individual consignor sales reports, reports to help search for specific sold items, total sales reports for any period, and  periodic "full" reports, in which reports are printed for every consignor/vendor, so that they can all be payed in 1 fast batch routine. 

Check Printing:

The built in check printing system can be used to write checks for vendor sales (or any other purpose), and the business owner can authorize checks remotely, without ever needing to be in the office.  Any employee, accountant, or other approved party can write checks, but can't print until the owner has signed them digitally, using a simple online process.  Any number of checks can be viewed and approved instantly in batches (hundreds or thousands, if needed, for large market or event situations).  This allows owners to manage multiple business locations easily.  Print positions can be adjusted to work with any check size or layout.

No Special Hardware or Supplies Required:

The software requires absolutely no special hardware or printing supplies to operate.  Off-the-self, low powered computers, standard letter printers and 8.5x11 paper, generic Avery type labels, and common CCD scan guns available in any office supply store are all that's needed to handle even the busiest locations.  Merchants' Village regularly ran 6 simultaneous cash registers, processing thousands of items per hour, using inexpensive netbooks with Atom processors, not only for the client machines, but also for the main server computer.  The system is fast and powerful, using even those readily available, small low cost PCs (you can find netbooks like that at Walmart for ~$200).  And just as important, you will never experience vendor lock-in, being forced to buy special proprietary hardware, supplies, or service from a single vendor (such maintenance often ends up becoming a tremendous expense for busy businesses).

Open Source:

Aside from the $0 price tag, the source code for the Merchants' Village software is released openly, so that you are entirely free to inspect and adjust the way it operates, tweak it, and make any changes, improvements, or customizations as needed.  A git repository on Source Forge ensures that the project can continue it's life even if the author ever discontinues involvement, and changes/improvements created by the community can be merged back into the project.  All historical versions will also always continue to be available.  You will not find that sort of future-proof guarantee available from any commercial software development company.  If you choose a commercial POS supplier and they ever go out of business, or make changes to new versions of their software, which you dislike or find unusable, you are simply out of luck, and may need to retool your business all over again using an entirely new computer system.  Such an event can be disastrous for well established businesses which rely on their existing software and trained employees to operate effectively.


The software includes a variety of additional unique features:
  • A built in time clock tracks employees as they clock in and out of shifts.  Optional photos can be taken by the time clock to ensure that only the correct employee is logging shift entries.
  • Sale events with special automatically adjusted scanned pricing and/or printed coupons, based on virtually any item, vendor, or time info can be set up quickly.
  • The software keeps track of rent due and payments made by consignors.
  • Fully automatic and manual backup features, to local and/or online storage mediums, are a built in option.
  • A map feature allows store owners to see where specific consignor/vendor items ("booths") are located on their floor plan.
  • Different levels of password protected admin controls allow only certain users to perform certain actions (accessing the POS, changing vendor info, writing checks, etc.).
  • The system has been tested completely on MS Windows, but also runs on Mac, Linux, and other platforms.
  • Network clients can be added in just a few minutes to provide additional fully functional cash register and label printing stations.
  • Wireless networks can be used in cases where that's deemed a responsible option (technically, the system can handle very heavy loads even over wireless connections, but wireless opens up serious security concerns for any POS system). 
  • Subcontractor consignment sales can be easily tracked using the flexible booth/item/price bar code scheme.
  • Other features to help with organizing group advertisements, and web site maintenance are included.
