当我想更新发票中的余额时,下面的代码正常运行而没有任何错误,但余额不会改变,为什么？

var queryService = new QueryService<Intuit.Ipp.Data.Invoice>(context);
    IList<Intuit.Ipp.Data.Invoice> list = queryService.Where(p => true).ToList();
    foreach (var invoice in list)
    {                  
        if (invoice.Id == order.Accounting.QBOID)
        {       
            if (invoice.Balance != order.Accounting.SurveyAmount)
            {
                Invoice invo = new Invoice();
                invo.Id = invoice.Id;
                invo = commonService.FindById(invo);
                invo.Balance = order.Accounting.SurveyAmount.HasValue ? order.Accounting.SurveyAmount.Value : 0; 
                invo.sparse = true;
                commonService.Update(invo);
            }
        }
