BigTime alternatives for architecture and engineering firms
BigTime is professional services software that ties time, expenses, invoicing, quoting, and resource management to project financials, and syncs with QuickBooks, Xero, or Sage Intacct. It serves consultancies and multi-office engineering firms alike. Firms that want proposals, people, and the knowledge in past work in the same place as delivery sometimes look at a broader workspace like Hubity.
