Is there any fintech in B2B space for expense management?

By Fintech in B2B i do not mean fintechs that are used to collect payments or any other thing which is consumer focused but i mean a fintech company that can provide a platform for business where they can manage their expenses , can pay salaries , can pay vendors/suppliers , a record of every expense can be checked by just a click. Total expense made till date. Total spend per unit , for example if you provide any monthly based service like providing a freight on monthly basis so unit cost till date of the month can be easily calculated .
