The inventory must be in electronic format. If you do not have an electronic version of the inventory, Maremagnum offers the free classification software MareMagnumPro, designed specifically for the book business and perfectly compatible with our system. If you already have a list of books or the bookshop prefers to use its own classification system, we can set up a customized conversion to manage the format already in use. Maremagnum, in fact, supports different formats, such as Homebase, Filemaker, Booktrakker, Livre-Rare-Book, Excel...

In order for the inventory to be successfully uploaded online, it is still essential that it meets some of the basic minimum requirements for our system: 
- the data must be delimited by tabs and must be saved as a text file (.txt). Once you have decided which format to use, it is necessary that this format remains the same for all future update files.
- if you use a book identification code, this code must be a unique numeric or alphanumeric code for each item and not to be reassigned when a book is sold. Re-assign a code can cause errors in the receipt of orders placed by customers. If there is any doubt that a book code may already have been used previously, it is recommended to start a new numbering, for example by preceding a letter to the numbers.
- Once you have decided how many fields to use, this number must always remain the same for all books. For example, if you decide to use 11 fields, then all book lists must contain 11 fields, even if some books contain empty fields without information.

Bookshops set their own shipping costs: these costs vary depending on the location of the bookshop and the shipping method used.

On Maremagnum it is required that bookshops ship using secure and traceable shipping methods (such as, for example, registered mail, courier).

All bookshops may use their own shipping costs or the shipping costs proposed by Maremagnum.

The rating of bookshops is done monthly based on the percentage of unavailable orders in relation to the total orders received in the previous month: thus, for example in December each bookshop will have a rating based on the month of November.

Below is the percentage of failed orders and the rating .
