The first Step is to create Business Module inside models.py

class Business(models.Model):
        name = models.CharField(max_length=200, db_index=True)
        slug = models.SlugField(max_length=200, db_index=True, unique=True)

        class Meta:
            ordering = ('name',)
            verbose_name = 'business'
            verbose_name_plural = 'business'

        def __str__(self):
            return self.name

Then use python manage.py migrate to migrate module inside your database.

Now open admin.py file and register this Module,

from .models import Business

# Register your models here.
class BusinessAdmin(admin.ModelAdmin):
    list_display = ['name', 'slug']
    prepopulated_fields = {'slug': ('name',)}
admin.site.register(Business,BusinessAdmin)

Now check your Django admin panel. It will show you New Business Module there with Add, remove feature using Form.

I hope this will helpful for you.
