Cash Invoice Form

POS finishes the sale without posting fiscal information

When a POS terminal registered for fiscalization starts, it checks whether it has access to its fiscal device — either the e-Tax Control Unit (Type A) or Infrasec (Type C). If the check fails, the POS cannot complete sales.

If the POS cannot reach the fiscal device for any reason, LS Central opens the Cash Invoice Form if it is available.

Note: For TCS-specific behavior (Infrasec TCS protocol), see Selling in the POS (TCS).

Normal Sale

When a cashier presses a tender key on the POS to complete a transaction:

  1. Transaction posting: LS Central posts the transaction as usual.
  2. Fiscal signing: The transaction details — amounts, VAT breakdown, slip number, and Client Registration ID — are sent to the control unit (via Hardware Station for Type A and Type C Hardware Station mode, or directly for Type C cloud mode).
  3. Response handling: The control unit returns a signature (kontrollkod) and its serial number. These are stored in the Fiscal Entry and printed on the receipt footer.
  4. On failure: The Out of Order flag is set on the Fiscal Interface Setup. The Cash Invoice Form opens so the cashier can collect customer details and complete the sale.

Note: Zero-amount transactions are not sent to the control unit; a success result is recorded automatically.

Cash Invoice Form

The LS Central solution for the Swedish fiscalization supports the possibility for the POS to continue to sell in cases when there is a connection problem to the physical memory, either Type A or Type C.

This is when the POS cannot connect with the e-Tax Control Unit or Infrasec to deliver needed information to tax authorities.

  1. The Cash Invoice Form opens automatically when the POS fails to register fiscal information.
  2. To finalize the sales in the POS, the cashier must fill in the following:
    • Customer Name.
    • Customer Address, one field for the whole address.
    • Customer Phone Number.
  3. When the Cash Invoice Form is used, the POS law is not applicable, instead it is the "Bokföringslagen" (accounting law).
  4. Note that the store ensures the correct customer data is keyed in.

Note: The POS manages to finalize a sale, that is, to post the sale to the transaction register without managing to post its fiscal information.

POS finishes the sale without posting fiscal information

It can happen that the POS manages to finalize a sale, that is, to post the sale to the transaction register without managing to post its fiscal information.

In such a case, the POS Terminal is in state Out of Order for the fiscal information and does not start a new sale.

What you can do in such a case:

  • Open the Transaction Register page.
  • The last sale that caused the error is, by default, the active one.
  • Make sure the last sale is active.
  • Select the button Print Copy.
  • The system automatically opens the Cash Invoice Form and lets the user fill in the information as usual.
  • Enter information into the Cash Invoice Form and click OK.
  • The POS should now be ready for the next sale.
