Varibill does not limit the amount of times a Source Collector can post billing records to your account or the amount of times a Data Import can be performed. The usage may differ between posts for the same record. Varibill keeps all records imported and does not replace previous records. It then can occur that one record has multiple values for the same day. You can either delete the records with values for which you do not want to bill, or Varibill will automatically use the first record during billing processing.
