Description:

Lemon is an open source point of sale for linux and other unix systems. It is targeted for the small and medium sized business, and has been conceived for ease of use.

It is a qt4/KDE4 application, so you must have installed kde4

It is considered a general point of sale, not focused to a specific sector. It can be used at a general store, a fast-food restaurant or a book store.

LemonPOS is translated to the following languages:

Spanish
Catalan
German
French -partially-
Chinesse -partially-
Portuguese BR -partially-


These are some features:
Tested with a parallel port ticket printer and a Star Micronics SP-100 thermal printer
Tested with a barcode scanner
It is probably that works with touch screens
It supports product photos
It has a grid view
It supports Group of products
It supports Special Orders (custom products)
and many other things...

and delivery date when adding another custom product.
- BUGFIX : Adding fix_roles.sql script to fix the roles on database. Run this on 0.9.2 or older databases.
- BUGFIX : Crash when using the Products Table View by default.
- BUGFIX : Squeeze Freezes when adding a new user, under certain conditions. May influence kernel version.
This bug is related to /dev/random. Now hash function uses /dev/urandom,
and the mouse need to be moved during the 'add user' action.
- BUGFIX : Unable to delete offers. This bug was present on older versions but with the Products table.
This is Related to QSqlTableModel class. To fix it, an own delete method was coded.
- BUGFIX : Offers Editor's validate method (date,amount,product) fixed.
- BUGFIX : Undefined values for balanceId and totalTax in the transaction table, only for purchases.
- BUGFIX : When editing a group in squeeze, the available products to add to the group, shows the
group products and raw products in the source products list.
- BUGFIX : Some transactions (tickets) were hidden in the "Reprint ticket" function.
- BUGFIX : On Special Order Editor, when selecting items from left list and adding to the right list
and having some in the right list, the price is not calculated as it should be.
- IMPROVEMENT : Product Editor now allows ZERO tax for products that need to be this way (tax free products).
- IMPROVEMENT : Increased refresh time for the model views (all tables on Squeeze), they refresh every
2 minutes instead of 5 seconds.
- IMPROVEMENT : Special Orders delivery date now is printed in the format: 'Mon 21 May, 4:30 PM'.
- IMPROVEMENT : Special Orders are now allowed to be marked as delivering on the same day.
- IMPROVEMENT : Now special Orders notes are up to 800 characters long.
- IMPROVEMENT : Some important fields (group elements, items in transactions...) are expanded to 1000 chars,
and other to 255 from lower values.
- IMPROVEMENT : Removed empty transactions from the Resume Sale selector. This empty transaction (only one)
is the one created at lemon start, it will be deleted on lemon exit.
- IMPROVEMENT : A lower limit for payment set to 1.00 in the Special Order Editor.
- IMPROVEMENT : The taxes and price for groups are calculated when needed by lemon. To report the correct tax and price.
- IMPROVEMENT : A splitter between the products grid and the purchase list in lemon. To allow resize them.
- IMPROVEMENT : Ticket Redesign to improve readability.
- UPDATE : Some translations where updated (de,es,fr).


NOTES:

- NOTE 1 : Special Orders can have two types of discounts simultaneously:
1.- On each component of the order (raw product)
2.- Occasional discount OR Client discount. Occasional discount only for the current
transaction ( prepayment, completing the order ) if you need on BOTH is needed to
add the occasional discount on each stage (prepayment, completing the order)

- NOTE 2 : Groups can have two types of discounts simultaneously:
1.- On the group product (the container).
2.- Occasional discount OR Client discount.
Group price and tax is calculated based on its components, at the needed moment.
The group has a Price-drop that is a discount % applied on each of its components. This is
used to calculate the group price and tax. For this reason, the group price, cost and taxes
are not editable on squeeze.

- NOTE 3 : If you are updating your database from 0.8.x version (or earlier) to a 0.9.X version then you
will need to run the "fix_roles.sql" script in the lemonpos/database_resources/ folder.
The symptom for running the fix_roles.sql script is that the "admin" user will be rejected as
an administrator, but you still login lemon with these user to sell things, but not for apply
occasional discounts or remove items or configure lemon ( unless LowSecurity mode is activated).

 the name

Score 50%

In the USA, "Lemon" is a term for an automobile that doesn't work. POS (standing for Piece of S***) is often applied to cars, like in the movie Men in Black where agent Jay complains about the Ford POS he has to ride in.

Together the app name evoked in my mind at first the image of a hunk of junk car.

Obviously people interested in Point of Sale software will know what else POS can stand for though ;)

In the feature list you say "It must work with a barcode scanner". Is this a future feature or is it already implemented? If so, what barcode sanner are supported by Lemon POS?

It depends on the operating system and the hardware (barcode reader) drivers.

Some readers are simple keyboards (they connect as a keyboard extension, with a connector called "wedge" or so.). This way, the application (lemonpos) does not knowns that, and thinks it was the keyboard that sends the keys (NUMBERS + ENTER key).

Other readers comes with an USB connector, or serial connector (DB9).

Some devices (readers) can work with the default USB/serial linux driver, and needs extra work at the application (lemonpos) or creating a new simple driver that gets values from the port (usb/serial).

It is possible that even the USB readers can act as a USB keyboard (if linux recognizes the reader as a USB keyboard).

In theory, if the readers acts as a keyboard, it must work with lemon.

As I dont have a barcode reader, I cant test if it really works.

Thanks for your detailed response. It's interesting that some barcode scanners even act as keyboards - not a bad idea! I would prefer such devices.

I wanted to use your application together with a barcode scanner to manage my fridge :)
But currently most devices are a bit to expensive for me, so I will wait some more months before buying such a device. Then I will tell you my experiences.

Hi...

Is mysql running?
Have you created the database with the script included?

The users (and other data) are stored into a mysql database, so mysql is required.

Lemonpos stores data into mysql database, including user's passwords.

Is mysql installed and running?
Have you created the database with the included script?

Maybe thats the problem.

If you read the database creation script the default username is in a list at the bottom.
Look for this line:

INSERT INTO lemondb.users (id, username, password, salt, name, role) VALUES (1, 'admin', 'C07B1E799DC80B95060391DDF92B3C7EF6EECDCB', 'h60VK', 'Administrator', 0);

So, try using 'admin' as the username and 'linux' as the password (ignoring the speech marks obviuosly). Hope this helps.

That means the mysql user for lemonpos does not exists or the password is incorrect, or the user access is not configured as it should be.

Did you run the database-creation-script ??
Is mysql running??

Do you like or dislike Ubuntu Unity?
 Yes, unity is alien technology!
 It is less confusing than Gnome 3 default, shell.
 Granny thinks it is much more usable than Gnome 2
 Canonical is embarrasing itself with this split project
 Gnome 3 default shell is much better
 I dislike Unity, Gnome 3 default shell is alien technology!
 None of the above, I like the 2Gb for free and Apple alike behavior. Will post a comment instead
