It is important to know that the changes are only needed at certain situation. If you not satisfy with above link answer and try to know the changed files. Then here are the change files that I mailed to the questioner. I have change the source code for the questioner's requirement. But I believe it is possible by plugin also. Here are the steps for nopcommerce3.9.
1. Go to the Nop.Web==>Controllers ==>CheckoutController.cs and replace
protected virtual JsonResult OpcLoadStepAfterShippingMethod(List<ShoppingCartItem> cart)
method by the bellow one
protected virtual JsonResult OpcLoadStepAfterShippingMethod(List<ShoppingCartItem> cart)
{
//Check whether payment workflow is required
//we ignore reward points during cart total calculation
bool isPaymentWorkflowRequired = _orderProcessingService.IsPaymentWorkflowRequired(cart, false);
//Intentionally make the isPaymentWorkflowRequired false. Default behavior change here
isPaymentWorkflowRequired = false;
if (isPaymentWorkflowRequired)
{
//filter by country
int filterByCountryId = 0;
if (_addressSettings.CountryEnabled &&
_workContext.CurrentCustomer.BillingAddress != null &&
_workContext.CurrentCustomer.BillingAddress.Country != null)
{
filterByCountryId = _workContext.CurrentCustomer.BillingAddress.Country.Id;
}
//payment is required
var paymentMethodModel = _checkoutModelFactory.PreparePaymentMethodModel(cart, filterByCountryId);
if (_paymentSettings.BypassPaymentMethodSelectionIfOnlyOne &&
paymentMethodModel.PaymentMethods.Count == 1 && !paymentMethodModel.DisplayRewardPoints)
{
//if we have only one payment method and reward points are disabled or the current customer doesn't have any reward points
//so customer doesn't have to choose a payment method
var selectedPaymentMethodSystemName = paymentMethodModel.PaymentMethods[0].PaymentMethodSystemName;
_genericAttributeService.SaveAttribute(_workContext.CurrentCustomer,
SystemCustomerAttributeNames.SelectedPaymentMethod,
selectedPaymentMethodSystemName, _storeContext.CurrentStore.Id);
var paymentMethodInst = _paymentService.LoadPaymentMethodBySystemName(selectedPaymentMethodSystemName);
if (paymentMethodInst == null ||
!paymentMethodInst.IsPaymentMethodActive(_paymentSettings) ||
!_pluginFinder.AuthenticateStore(paymentMethodInst.PluginDescriptor, _storeContext.CurrentStore.Id) ||
!_pluginFinder.AuthorizedForUser(paymentMethodInst.PluginDescriptor, _workContext.CurrentCustomer))
throw new Exception("Selected payment method can't be parsed");
return OpcLoadStepAfterPaymentMethod(paymentMethodInst, cart);
}
//customer have to choose a payment method
return Json(new
{
update_section = new UpdateSectionJsonModel
{
name = "payment-method",
html = this.RenderPartialViewToString("OpcPaymentMethods", paymentMethodModel)
},
goto_section = "payment_method"
});
}
//payment is not required
_genericAttributeService.SaveAttribute<string>(_workContext.CurrentCustomer,
SystemCustomerAttributeNames.SelectedPaymentMethod, null, _storeContext.CurrentStore.Id);
var confirmOrderModel = _checkoutModelFactory.PrepareConfirmOrderModel(cart);
return Json(new
{

});
}
2. Go to the Libraries==>Nop.Services==>Orders==>OrderProcessingService.cs and replace
public virtual PlaceOrderResult PlaceOrder(ProcessPaymentRequest processPaymentRequest) method by the bellow code

if (!skipPaymentWorkflow)
{

if (paymentMethod == null)
throw new NopException("Payment method couldn't be loaded");

3. Please go to the Nop.Web==>Views==>Checkout and replace OnePageCheckout.cshtml view's code by the bellow one

if (!Model.ShippingRequired)

}
if (Model.DisableBillingAddressCheckoutStep)
{
shippingAddressStepNumber--;
shippingMethodStepNumber--;
paymentMethodStepNumber--;
paymentInfoStepNumber--;
confirmOrderStepNumber--;
}
}
by
@{
//step numbers
int billingAddressStepNumber = 1;
int shippingAddressStepNumber = 2;

//int paymentMethodStepNumber = 4;
//int paymentInfoStepNumber = 5;
int confirmOrderStepNumber = 4;
if (!Model.ShippingRequired)

The order look like the bellow image at admin side
