With Advanced Supply Type options, you can now easily generate IRNs for all your invoices including while billing to SEZ and Export clients. 


Supply Type

A Supply Type in an e-invoice denotes the categories of the two parties involved in the transaction. The following supply types are included in the GST: 


  1. B2B: Business to Business
  2. B2C: Business to Consumer
  3. SEZ: Selling to either a Registered SEZ Unit or a SEZ Developer 
    1. SEZ, with Payment
    2. SEZ, without Payment
  4. Export: Billing to an overseas client
    1. Export, with Payment
    2. Export without Payment
  5. Deemed Export: Supply of goods (not services) that are delivered in India, but eventually meant for exports.


With Refrens, you can now generate e-invoices for both SEZ and Exports. For the Without Payment options, the tax amount will be deduced to be 0, irrespective of the applied tax rate.


Selecting the Supply Rate

Once you add/edit or select an existing client from the invoice - we will automatically update the taxpayer type for your client. Based on these, you can select whether the supply type for the e-invoice should be regular B2B, SEZ or Export. 


Let's say you are billing an overseas client. You have a Letter or Undertaking and want to generate an e-invoice under Export without Payment. 



Once you have selected an Overseas Client (non-IN), your GST configurations will automatically be updated to support Export invoices. 


  1. Click on Add Tax/Configure GST
  2. Select IGST as a GST Tax type
  3. Export without Payment as your Supply Type. 


Note: Under Export/SEZ Without Payment options, the tax amount will automatically be set to 0 irrespective of the Tax rate mentioned.


 Note: If your client is a registered SEZ Unit/Developer, your GST configurations will automatically be updated to SEZ supply types. All the other steps remain the same as above. 


For export invoices, ensure that you mention the correct conversion rates for which you want to create the e-invoice on. You can set the Conversion rates in your invoice itself: 



While generating IRN, we will use the exchange rate mentioned here to generate an e-invoice.
