Computer-implemented method for preparing offer and/or order data of an object to be individualized

A non-transitory computer-readable medium having instructions executable on a computer, which, when executed on a computer, cause the computer to carry out the following steps:

• providing a purchasing system having a user interface, an inventory management system, and a data interface between the purchasing system and the inventory management system in a computer system;
• providing individualization data for individualizing the object in a storage unit of the computer system;
• receiving a first user input comprising object selection data of the object to be individualized via the user interface;
• receiving a further user input comprising at least one selected selection position for individualization data on the object to be individualized;
• transmitting data via the data interface after at least one of the above-mentioned steps between the purchasing system and the inventory management system, wherein the data comprise at least the object selection data, the at least one selected selection position, a data set of object data of the object to be individualized, wherein the object data define object components and at least two selection positions for the individualization data on an object, object configuration data, which are based on the at least one selected selection position, the object data, and the individualization data, and/or price data based on the object configuration data;
• generating offer and/or order data for the object to be individualized from the price data and the object configuration data by means of the inventory management system;
• wherein the method comprises the following steps before the reception of the first user input:
• displaying a digital representation of objects to be individualized via the user interface;
• and
• selecting one of the objects to be individualized by a user to generate the object selection data;
• wherein the digital representation comprises at least two representation levels, wherein one of the at least two representation levels comprises a first partial representation of the object and a further of the at least two representation levels comprises at least one further partial representation of the object, wherein an overlay of the partial representations displays an overall representation of the object and individual partial representations of the object are exchangeable or manipulable without changing the other partial representations, wherein partial representations can be stacked, wherein a first symbol at a first position of a first partial representation stacked below a second symbol at a second position of a second partial representation is visible on the object through a transparent image region of the second symbol at the second position of the second partial representation, and wherein the overall representation of the object is visible with the first and second symbols.
