Validations

Validations in e-Invoicing System
  1. E-Invoice request JSON data has to be validated as per the e-Invoice JSON Schema given in the notification.
  2. Version of the Schema is mandatory and should be latest as per the notified in latest notification.
  3. IRN should not be passed as part of the request; it is generated by the e-Invoice system and sent as response.
  4. The following fields should have one of the values given in the master codes.
    • Supply Type of Transaction
    • Document Type
  5. The category of transaction of ‘Business to Consumer (B2C)’ invoices will not be considered and hence the API interface should not request for IRN for these transactions.
  6. Document number should not be starting with 0, / and -. Also, alphabets in document number should not have alphabets in lower cases. If so, then request is rejected.
  7. Supplier should ensure that the unique invoice number is being generated for the financial year for each invoice, in his ERP/manual system. The financial year is derived from the the date of invoice. The financial year starts from 1st April and ends on 31st March.
  8. Duplicate IRN requests are not considered. That is, if the IRN is already generated on particular type of document and document number of the supplier for the financial year, then one more IRN cannot be generated on the same combination.
  9. e-invoice(IRN) cannot be re-generated for the cancelled e-invoice(IRN) also.
  10. Request for the IRN/e-Invoice can be made only by the supplier of the goods or services.
  11. In case of e-commerce transactions, the e-Commerce Operator can request for the IRN/e-invoice on behalf of the supplier. In this case, the e-Commerce Operator should have been registered on the GST portal as e-Commerce Operator and pass eCom_GSTIN accordingly.
  12. In case the supplier is SEZ unit or SEZ developer, then he cannot generate e-Invoice.
  13. The Document Date can be yesterday or today’s date.
  14. ‘Reverse Charges’ can be set as ‘Y’ in case of B2B invoices only and tax is being paid in reverse manner as per rule. Even in case of Reverse Charged invoices, the seller has to generate the IRN.
  15. Recipient GSTIN should be registered and active. In case of transaction of direct export, recipient GSTIN has to be URP and state code has to be 96, POS should be 96
  16. In case, Buyer is SEZ unit or SEZ developer, the Bill to State code should be 96 and also POS should be 96.
  17. First two digits of the supplier / recipient GSTIN should match with the state code passed in the seller / buyer details accordingly.
  18. PIN Codes are validated against the States, they belong to.
  19. If ‘Shipping party’ is provided, then the transaction is considered as ‘Bill To-Ship To’.
  20. If ‘Dispatching party’ is provided, then the transaction is considered as ‘Bill From – Dispatch From’.
  21. If Shipping and Dispatching parties are provided, then the transaction is considered as ‘Combination of Both’ (Bill From – Dispatch From and Bill To- Ship To).
  22. In case of export transactions for goods, the ‘Ship-To’ address should be of the place/port from where the goods are being exported.
  23. In case IGST on intrastate supply, tax rates and tax values related to IGST should be passed, and seller state code and buyer state code should be same.
  24. In case of Goods, the state code of the Seller GSTIN and state code of the Buyer GSTIN will decide whether the supply type is Interstate or Intrastate. That is, if the State code of Seller and buyer is same, then it is intra-state, otherwise it is inter-state.
  25. In case of Services the state code of the Seller GSTIN and state code of POS will decide whether the supply type is Interstate or Intrastate. That is, if the State code of Seller and state code of POS is same, then it is intra-state, otherwise it is inter-state.
  26. In case of Exports, the supply is always Interstate whether Goods or Services.
  27. JSON payload size cannot exceed 2MB.
Validations on Items:
  1. Serial number of the item is verified for duplicate values.
  2. Each item needs to have valid HSN code with at least 4 digits. That is, items of goods type should be 4 or 6 or 8 digits and items of service type should be 4 or 5 or 6 digits. HSN Code should be valid as per the GST master.
  3. If Is_Service is selected, then the HSN codes must belong to services.
  4. Each item should have valid Unit Quantity Code (UQC) as per the master codes, in case of goods.
  5. Quantity and Unit Quantity Code are mandatory for Goods and optional for Services.
  6. Tax rates are being validated. Only the allowed tax rates will be accepted.
  7. In case of intra-state transaction, the sum of SGST and CGST tax rates should be entered as GST Rate.

  9. In case of export transaction, IGST tax rate and value has to be passed.
  10. In case the buyer is SEZ unit or SEZ developer, then IGST tax rate and value has to be passed irrespective of state of the buyer.
  11. Maximum number of items in each invoice should not exceed more than 1000 items and a minimum of 1 item should be available
Calculation of Values:
  1. The following summation validations are to be done for items
    • Gross Amount of Item = Quantity X Selling Unit Price Taxable Value of Item = Gross Amount of Item – Discount
    • SGST Value of Item = Taxable Value of Item X GST Rate / 2, if intra-state CGST Value of Item = Taxable Value of Item X GST Rate / 2, if intra-state
    • IGST Value of Item = Taxable Value of Item X GST Rate, if inter-state Cess Value of Item = Taxable Value of Item X Cess Rate
    • State Cess Value of Item = Taxable Value of Item X State Cess Rate Total Value of Item = Taxable Value of Item + SGST Value of Item + CGST Value of Item + IGST Value of Item + Cess Value of Item + State Cess Value of Item + Non-Advol Cess Value of Item + State Cess Non-advol value of Item + Other charges.
  2. The following summation validations are to be done on Invoice total
    • Total Taxable Value = Taxable Value of all Items
    • Total SGST Value = SGST Value of all Items
    • Total CGST Value = CGST Value of all Items
    • Total IGST Value = IGST Value of all Items
    • Total Cess Value = Cess Value of all Items + Non-Advol Cess Value of all Items
    • Total State Cess Value = State Cess Value of all Items + State Cess Nonadvol Value of all Items
    • Total Invoice Value = Total Taxable Value + Total SGST Value + Total CGST Value + Total IGST Value + Total Cess Value + Total State Cess Value + Total Non-Advol Cess Value + Total Other charges – Invoice Discount + Invoice Other charges + Round-off amount
  3. Calculated value / amount in above points can be between actual calculated value / amount and calculated value / amount rounded up to next rupee
  4. The round-off value can be up to Rs. 9.99
Validations on e-waybill:
  1. E-waybill can be generated only if E-way Bill related details are passed where distance is mandatory.
  2. E-way Bill is not generated for document types of Debit Note and Credit Note and Services.
  3. E Way Bill can be generated provided at least HSN of one item belongs to goods.
  4. If only Transporter Id is provided, then only Part-A is generated.
  5. If mode of transportation in ‘Road’, then the Vehicle number and vehicle type should be passed.
  6. If mode of transportation is Ship, Air, Rail, then the transport document number and date should be passed.
  7. The Vehicle no. should match with specified format and exist in Vahan database.
  8. E-Waybill will not be generated if the supplier or recipient GSTIN is blocked due to non-filing of Returns.
  9. Pincode of Recipient GSTIN is mandatory if Ship-To details are not entered
  10. PIN-PIN distance is validated.
  11. In case of export of goods, shipping address should have been passed during generation of IRN
  12. In case incomplete information has been passed for generation of E Way Bill, then IRN will be generated and returned but not E Way Bill number. However subsequently, based on IRN, with Part B details of E Way Bill, E Way Bill can be generated.
  13. E-waybill cannot be generated for only Services.
