Vouchers sold via incert are posted into the Protel PMS. This requires both the Protel Voucher Management module and the "Protel Voucher API" interface. When a voucher is sold via incert, it is automatically transferred to the Protel voucher system. This allows for seamless revenue posting without the need to manually access Protel.

If you are interested in this interface, we’d be happy to hear from you at sales@incert.at. Please note that both the "Protel Voucher Management" and the "Protel Voucher API IFC" must be commissioned via Protel or your installer. Additionally, your IT must provide an HTTPS endpoint for the Protel ComServer (see below).

Process

1. The customer purchases a voucher online or a staff member issues it via incert.
2. incert transmits the voucher value and payment method to Protel.
3. Protel opens a walk-in account and posts the voucher and payment using the “INCERT” profile (or an alternative one if defined).
4. The walk-in account must be checked out (ideally daily) to generate an invoice. This invoice is stored in the Protel voucher management system.
5. The voucher and its payment are now recorded within Protel’s voucher management.

Example

Below you can see vouchers sold in incert and transferred to the Protel "protel voucher" system:

Use cases

incert as the central voucher system (recommended)

Posting to Protel is used purely for revenue recording—often in combination with the redemption interface. incert remains the master system, while Protel is used for accounting purposes only. The voucher balance remains managed in incert, which allows integration with other systems (POS, booking engines, etc.).

incert as a pure sales system (not recommended)

Alternatively, incert can act as a sales-only platform, while Protel handles the full management and redemption of vouchers. In this case, Protel becomes the leading system, limiting incert’s functionalities and excluding further integration options. We therefore recommend keeping incert as the master system.

Important notes

• The required interface is only available for on-premise installations. Protel Air is not supported.
• Only the sale of vouchers (or tickets/cards) can be posted. Sales of physical products are not supported, as there is no voucher code to transmit.
• Protel does not support posting of discounts, shipping fees, or order cancellations.
• For portal systems with a multi-property setup: incert can define to which Protel property a transaction should be posted based on the issuing user. For online sales, vouchers from a specific sub-shop can be posted to a corresponding Protel property—provided consistent booking settings (MOPRef, VoucherType, etc.) are in place. In practice, this is not usually needed in hotel groups, as incert typically posts to the central accounting system of the umbrella organization instead of each individual property. On-site sales are recorded by the individual hotels directly in their own PMS.
• Installation requires collaboration with Protel/your installer and your internal IT team. The Protel ComServer runs on your company server and must be made accessible from the internet by providing an HTTPS endpoint. This endpoint will allow incert to connect to the ComServer.
