Common Questions
After the Leqi Platform upgrade, what needs to be modified for the reverse invoicing self-use scenario?
After the upgrade, enterprises that purchase scrapped products for their own use must add payment channel and transaction order number fields, and blue invoices must include this information, otherwise invoicing is not possible. At the same time, the Leqi invoicing mode code becomes optional, but the content filled in must be validated based on whether transaction information is passed.
After the Leqi upgrade, what fields need to be changed for all invoicing capabilities?
The field "invoice issuance method code" must be added and is required. When the relationship type is self-use, head office-branch, parent-subsidiary, or other control relationship, fill in "5: self-built platform invoicing"; when there is no equity relationship, fill in "4: third-party platform invoicing." Failure to modify will block invoice upload.
What impact does the Leqi upgrade have on the invoicing capability for commodity barcodes?
For the two interfaces involving baijiu product information download, the request parameter "production enterprise taxpayer identification number" is changed to "taxpayer identification number," and the return parameters are modified accordingly. Enterprises that have subscribed to this capability need to complete the input and output parameter transformation, otherwise they cannot normally download baijiu product information.
What needs to be modified for natural person information collection after the Leqi upgrade?
Newly added non-mandatory fields such as the natural person flag of the seller, the natural person ID type, ID number, and nationality code of the buyer and seller. In specific scenarios, they must be filled in according to rules; failure to adapt will block invoicing.
