This is why you should use a true B2B service, and not just use a public price comparisons site:
1 – B2B services are permanently updated, at least once a day and up to every hour. On the contrary, many comparators are updated only few times per week. Many tines, the price they display is not the very current one.
2 – Web crawlers are fully independent. They go directly to the source and scrape the information published on the website. On the contrary, comparison sites usually receive data provided (and often filtered) by the vendor. Disturbing facts are often hidden.
3 – Direct scraping by the B2B service allows on site price comparison. You can know the price of one article on other vendors’ websites, while surfing in a reference vendor website (for example your own website). Price comparison sites can never do that.
4 – B2B services can display interesting consolidated analyses. Public price comparison sites can’t.
5 – Your B2B provider can integrate your internal data and provide you with files you can integrate in your IT system, to feed your internal reporting tools or your automatic pricing system.
