You may see the message 'The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.' when processing large orders.

This is an issue between our system and Accentis that is solved by increasing the message size. Firstly try to update the maxReceivedMessageSize, maxBufferSize, and maxBufferPoolSize in the application configuration file.

  <system.serviceModel>

        <bindings>

            <basicHttpBinding>

                <binding name="BasicHttpContextBinding_AccentisConnect" allowCookies="true"  

                                        maxReceivedMessageSize="99999999"

                                        maxBufferSize="99999999"

                                        maxBufferPoolSize="99999999"/>

                <binding name="BasicHttpContextBinding_IAccentisDynamicSvc" allowCookies="true"

                                        maxReceivedMessageSize="99999999"

                                        maxBufferSize="99999999"

                                        maxBufferPoolSize="99999999"/>

            </basicHttpBinding>

            <customBinding>

                <binding name="CustomBinding_IHelpPage">

                    <textMessageEncoding messageVersion="Soap12" />

                </binding>

            </customBinding>

        </bindings>

        <client>

            <endpoint address="http://accentisip/AccentisConnect/General" binding="basicHttpBinding" bindingConfiguration="BasicHttpContextBinding_AccentisConnect" contract="AccentisWS.AccentisConnect" name="BasicHttpContextBinding_AccentisConnect" />

            <endpoint address="http://accentisip/AccentisConnect/Dynamic" binding="basicHttpBinding" bindingConfiguration="BasicHttpContextBinding_IAccentisDynamicSvc" contract="AccentisWS.IAccentisDynamicSvc" name="BasicHttpContextBinding_IAccentisDynamicSvc" />

            <endpoint binding="customBinding" bindingConfiguration="CustomBinding_IHelpPage" contract="AccentisWS.IHelpPage" name="CustomBinding_IHelpPage" />

        </client>

    </system.serviceModel>

If this still does not work, then contact Accentis and request the default message size to be increased
