In this article, we are going to get a customer income from Quickbooks online and show(print) it in text formatted string and download it in a text file.

If you have not seen How To Get Reports From Quickbooks Online Using C# then I recommend you to see that first. in that article, I described how to get Reports from Quickbooks.

  • First, we have to create a method that takes 2 arguments.
  1. CustomerID– Quickbooks online Customer ID (For receiving a particular customer’s report by its ID).
  2. CustomerName– Quickbooks online Customer Name.
  • as we discussed in How To Get Reports From Quickbooks Online Using C# from Quickbooks, we will get a customer income report from Quickbooks and pass it to another function that returns the report in the formatted text string.
  • We have to give ReportName “CustomerIncome” and CustomerID of which customer report we need.
  • The code is as below.
  • GetCustomerIncomeReport method
public ActionResult GetCustomerIncomeReport(String CustomerID, String CustomerName)
{
  CustomerIncomeReport CustIncomeReport = new CustomerIncomeReport();
  try
  {
    OAuth2RequestValidator oauthValidator = new OAuth2RequestValidator(Access_token);
    // Create a ServiceContext with Auth tokens and realmId
    ServiceContext serviceContext = new ServiceContext(RealmId, IntuitServicesType.QBO, oauthValidator);
    serviceContext.IppConfiguration.MinorVersion.Qbo = "23";
    serviceContext.IppConfiguration.BaseUrl.Qbo = QboBaseUrl;


    //JSON required for QBO Reports API
    serviceContext.IppConfiguration.Message.Response.SerializationFormat = Intuit.Ipp.Core.Configuration.SerializationFormat.Json;

    //Instantiate ReportService
    ReportService reportsService = new ReportService(serviceContext);

    //Set properties for Report
    //reportsService.start_date = startDate;
    //reportsService.end_date = endDate;
    String reportName = "CustomerIncome";
    reportsService.customer = CustomerID;


    //Execute Report API call
    Report report = reportsService.ExecuteReport(reportName);

    string ReportStr = string.Empty;

    //Format the report data and print to the console
    ReportStr = PrintReportToString(report);

    CustIncomeReport.CustomerID = CustomerID;
    CustIncomeReport.CustomerName = CustomerName;
    CustIncomeReport.ReportText = ReportStr;

  }
  catch (IdsException ex)
  {

  }
  catch (Exception ex)
  {

  }
    return View(CustIncomeReport);
}

CustomerIncomeReport Model (CustomerIncomeReport.cs)

public class CustomerIncomeReport
{
   public string CustomerID { get; set; }
   public string CustomerName { get; set; }
   public string ReportText { get; set; }
}
  • GetCustomerIncomeReport View (GetCustomerIncomeReport.cshtml)

    /**/

    ViewBag.Title = "GetCustomerIncomeReport";

Now we have to set the GetCustomerIncomeReport page link on the customer list page.so the user can see any customer’s income report.

Let’s set Link in Customer List view page,

  • Customer View
@model List<Intuit.Ipp.Data.Customer>

@{
    ViewBag.Title = "GetCustomer";
}

<h2>Quickbooks online Customer List</h2>

<div>
    <table class="table table-bordered">
        <tr>
            <th>QBO ID</th>
            <th>Display Name</th>
            <th>Given Name</th>
            <th>Family Name</th>
            <th>Email</th>
            <th>Primary Phone</th>
            <th style="text-align:center;">Income Report</th>
        </tr>

        @foreach (var Cust in Model)
        {
            <tr>
                <td>@Cust.Id</td>
                <td>@Cust.DisplayName</td>
                <td>@Cust.GivenName</td>
                <td>@Cust.FamilyName</td>
                @if (Cust.PrimaryEmailAddr != null && !string.IsNullOrEmpty(Cust.PrimaryEmailAddr.Address))
                {
                    <td>@Cust.PrimaryEmailAddr.Address</td>
                }
                else
                {
                    <td></td>
                }

                @if (Cust.PrimaryPhone != null && !string.IsNullOrEmpty(Cust.PrimaryPhone.FreeFormNumber))
                {
                    <td>@Cust.PrimaryPhone.FreeFormNumber</td>
                }
                else
                {
                    <td></td>
                }

                <td style="text-align:center;"><a href="@Url.Action("GetCustomerIncomeReport", "Home", new { CustomerID = Cust.Id,CustomerName= Cust.DisplayName})" target="_blank"><img src="~/Content/Images/BalanceSummaryIcon.png" height="25" width="25" /></a></td>
            </tr>
        }

    </table>
</div>

so this way we can get the customer income report from Quickbooks online.
