Re: POS with local storage on disconnected networks

Then again, ODOO POS offline features, works fine for small, remote, low transaction Shops.

You cant rely hundreds of offline order sales to the web storage in the browser, wich has a 5MB size by design, because it is not persistent, if your browser crashes, or you cannot syn in time... YOU LOST all that information. Then what are going to do?? Invent all the information??

As pointed by Mr. Blanco, wherever you are, your records must match with the document you provided the customer... or you will go to Jail for TAX evasion and dishonest tax reporting.

So for serious business, you will not consider Odoo Pos Offline.

Good Luck!!

Mr. Caudal:


Thank you, sir! 

Mr. Blanco:

"This is mostly not acceptable by tax entity. "

I suppose it depends on which tax entity you're referring to. I know for a fact that it's legal in the United States, and I'm not a tax attorney, but it seems to meet the VAT req's for the UK.

"The voucher issued to the customer, call it invoice, receipt, etc should match exactly with your sale records."

Don't take this the wrong way, but in many cases it actually shouldn't. Again, exposing sequential primary keys/fkeys is generally a terrible idea. I've included good sources and so see below:


In fact, if one of you jokers want to poney up to the table and lay down some money, I can demonstrate it with a .ASP web application: Every customer, including their address. 100% legal... 100% open source... It's that serious... 

Still, there are the security risks associated with "fuzzing" —which is less than legal....

If you want a real world example, you can Google "weev" and read about how he compromised 100,000 AT&T customers:
(Courts overturned the conviction , btw)

"(Number, date (time sometimes) type of document)."
 That would come from the "proforma invoice".

I think Cody proposal matches the requirements as far as I can understand: 2 independent sequence numbers (one for the ticket and one for the invoice).
* Ticket displays the random number
* Invoice display random+standard no gap invoice number

You have full traceability in both direction

"I do not know if you are following the thread in same way I am doing it."

Let me try again:

"How will you respect the No Gap Sequence of Invoices Being Off Line?"


I wont. I'll generate a "proforma invoice" in the "field", which would list a random number (I would have to give more thought to the seed); hand it to the customer, shake their hand, and go about my business.  

Then, wherever/whenever the connection is restored, I have Odoo "push thousands of invoices thorught syncronization processes", storing the random number alongside the "No Gap Sequence".

Now, you're talking about a supermarket, but the concept is identical.

"- What about Customers?"
   I use the random number.


"- What about accounting?"
   They use the "No Gap Sequence", because that's what the tax man wants.

this helps !
a great deal of supermarket clients in biological stores say no when asked if they want a ticket.
as a matter of fact, we're looking for a module that enables a button in the POS screen asking if customer wants a printed ticket (with the EPSON printer *not* printing by default, but only when the button is pressed).
do you know of such a module for v8.0?
thx, Ron

Well, normally the company must print the invoice in the moment that occurs the transaction (probably most of business have to do this anywhere, europe, usa, latin america, etc), so, by design ODOO POS, cannot generate the Invoice Offline, therefore, the offline feature is mostly useless, you have to be all the time online to sell goods.

Do not Confuse "invoice" with "ticket" in EEUU the ticket is given (and it can be doe properly off-line) and the invoice is asynchornous (frequently sent by email afterwards).
