How each number is marked
Official
Printed on an ETA SDK page retrieved for this edition.EGKits setting
Chosen in EGKits V10. It is not an authority quota.Estimate
Calculated from the stated latency and concurrency.Not confirmed
The retrieved official pages do not state this number.
Official
500 receipts and 1.5 MB
Official maximum for one e-receipt submission, from the ETA receipt FAQ.
Not confirmed
No published hourly submit quota
The governance table limits read APIs. It does not list Submit Documents or Submit Receipts.
Distinction
Signing is not submission
Invoice CAdES-BES uses the local token. Receipt batches are a separate path, and a signature rate is not an ETA acceptance rate.
What the guides cover
E-Receipts
POS architecture, the receipt lifecycle, batch submission of up to the documented 500 receipts and 1.5 MB, automatic submission, and how to estimate hourly throughput when no official per-hour quota is published.
E-Invoicing
The invoice lifecycle, CAdES-BES signing with EGKits.EtaSigningAgent, bulk submission, separate automatic-signing and automatic-submission switches, and the difference between token signing capacity and ETA submission capacity.
