When sending an invoice the system may reject it with an error message. Most errors come from a few simple mistakes: a forbidden space in a field, an incomplete economic code or an expired goods ID. Each error is listed below with its cause and fix. If you use AkamTax, AkTax.app or ERPTax, make these corrections in the software itself.
Date and number errors
- Invoice date and time not valid (code 0202)
- Cause: the invoice date is outside the system's allowed window. Fix: move the date into the allowed window and send invoices without delay.
- Reference invoice tax number does not match
- Cause: the invoice number is a duplicate or the reference tax number does not match the original. Fix: the number of return, correction and cancellation invoices must differ from the original. If the invoice is registered but your software shows an error, contact support.
- Invoice serial does not match the template
- Cause: the invoice number must be 10 digits, numbers only. Fix: pad it to 10 digits with zeros (e.g. 0000000001) and avoid dashes, brackets and letters.
Economic code and party errors
- Buyer's economic code too long
- Cause: a wrong economic code or an undefined buyer type. Fix: enter the economic code and national ID and set the customer type (natural or legal). A legal entity's national ID is its economic code.
- Buyer's economic code too short
- Cause: natural persons with a tax file have a 14-digit economic code. Fix: enter the 14-digit code; to look it up use the tax authority's inquiry service.
- Economic code does not match the template (legal entities)
- Fix: for a legal entity write the national ID as the economic code.
- Seller's economic code does not match the system
- Fix: correct the economic code and national ID in the company details.
- Buyer person type not valid (code 0110)
- Fix: set the buyer type in the customer record.
- Buyer postcode over 10 digits
- Fix: correct the postcode.
Goods, template and amount errors
- Goods/service ID does not match the system (code 0333)
- Cause: the ID is expired, wrong or missing from the goods and service ID system. Fix: find the right ID, or use a general ID, or get a specific ID (goods from the national trade window, services from the national numbering centre). Full guide: goods and service ID.
- VAT rate does not match
- Cause: the ID's exempt/taxable status in the system differs from the software. Fix: make the item's tax status match its ID.
- Invoice template or subject not valid (codes 0107 and 0108)
- Fix: pick the correct template and subject when editing the invoice. Each type and template is explained in invoice types.
- Total before discount is zero
- Fix: add at least one item line with an amount above zero.
- Cash and credit cannot be empty
- Fix: fill in the cash and credit settlement amount.
- Seller's contract registration ID not valid
- Cause: the contracting agreement is not registered in the tax folder or the ID is wrong. Fix: register the contract in the tax folder, enter the ID issued and make sure the other party has approved it.
Signature and tax memory ID errors
- “The operation could not be completed because of an error”
- Cause: one possible reason is that the unique tax memory ID has been deactivated. Fix: get a new ID in the tax folder and set the software up again.
- “Request not registered” or “signature not correct”
- Common causes: a deactivated ID, public and private keys that do not match, or an illegal character (quote, space, dash) in seller, item or customer names. Fix: review the fields and run the software's seller-inquiry option. If the problem is the system clock, go to fixing the system-time error.
The “Pending” status
- If your software needs updating, update it and query the invoice.
- If the system is still processing, do not resend; wait for the final status. It ends as either “success” (nothing more to do) or “failed” (correct the error and resend).
If it is not fixed
Note the message and error code and contact Akam Data support. The overall path is also in the invoice issuing process.
