Changing the payment device and its effect on invoice numbers (desktop)

Changing the billing device affects the invoice numbers that are issued after the change. That is why it is important to distinguish between editing an existing payment device and opening a new payment device.

This article is about the affiliate Zoyya web app on PC.

When to use this option?

Use this instruction when you need to decide:

1. whether the existing payment device is being modified,
2. if a new payment device is opened,
3. if another payment device is set as default,
4. how the change affects account numbers.

The existing device is edited for minor settings, for example device name, default operator, deposit, automatic printing, printer, payment types or replacement of the fiscal certificate.

A new billing device is opened when the business premises, label of the billing device, company, computer or other device from which invoices are issued, the actual billing location changes, or when a new sequence of invoice numbers needs to be started.

Operation steps

Check if you need to edit an existing device or open a new one

1. If you are only changing the name, default operator, deposit, automatic printing, printer, payment types or certificate, edit the existing device.
2. If you are changing business premises, business premises label, billing device label, company or billing location, create a new device according to the article Creating a new billing device (computer).
3. If the new device is to become the device for issuing future bills, set it as the default according to the article Setting the default billing device (computer).

Editing of the existing payment device

1. On your computer, open Zoyya.
2. In the left menu, open Receipts.
3. Open the Cash register.
4. Open Cash register settings.
5. Open Payment devices.
6. Click a device in the table or click Edit on the default device.
7. Edit the data that changes.
8. If you are changing the fiscal certificate, click Replace fiscal certificate, select the new .p12 file, enter the password and click Unlock certificate.
9. Click Save.
10. After saving, check that the device has no warnings.

Set new device as default

Setting a new device as the default is described in the article Setting the default payment device (computer).

After the change

1. Open the cash register on the new default device.
2. If receipts are printed, check the article Setting up a printer for receipts (computer).
3. Check the article Types of payments on a payment device (computer).
4. Check the first issued invoice on the new device in the article Overview of issued invoices (computer).

The account number in Zoyya consists of a serial number, a business premises number and a payment device number. An example of a structure is:

1/PP1/1

The serial number is kept by payment device and year. This means that each payment device has its own sequence of numbers.

What is being edited on an existing device

The following are edited on the existing device:

1. Device name,
2. Default Operator,
3. Deposit,
4. Name of branch,
5. Branch address,
6. Automatic receipt printing,
7. fiscal certificate,
8. printer settings,
9. payment types and discounts by payment type.

When editing an existing device, the field Company is not used to switch the device to another company. When the device should belong to another company, a new billing device is created for that company.

When a new payment device is opened

A new payment device is opened when changing:

1. place of payment,
2. computer or other work device,
3. business premises,
4. business premises sign,
5. payment device mark,
6. the company for which invoices are issued.

The old billing device should not be used for the new situation because the new device starts from number 1 for that year, while the old device keeps its previous sequence.

What happens to previously issued invoices

Already issued invoices are not changed. Their numbers, fiscal data, business premises, billing device, JIR, ZKI and status remain recorded as they were at the time of issue.

In-App Alerts

When changing the default device, the application displays a warning:

Are you sure you want to change the payment device?

The warning states that account numbers are affected by the change. When the selected device has already been used, the application displays an additional note that the device has already been used.
