​
How Invoicing Works

For every checkout that is sent, Etherly Sync automatically creates three documents in Elorus, in a strictly defined order.

​
The 3 documents

1. Accommodation Invoice

myDATA type: 11.2
VAT: 13%
The primary document for the accommodation service.

2. Payment Receipt

Linked to the invoice.
Confirms payment received.
Issued immediately after the invoice.

3. Climate Resilience Fee

Separate cash receipt.
Calculated per night and category.
Split per season if the booking spans winter/summer.
The creation order cannot be changed: invoice → receipt → fee. If any step fails, the system stops and records the error — subsequent steps are not attempted.

​
myDATA submission

Every document issued in Elorus is automatically submitted to myDATA, provided the option is enabled in settings.
  • myDATA returns a MARK (Unique Registration Number) for each document
  • If myDATA submission fails, the document is still issued in Elorus — manual submission may be required
A myDATA failure does not cancel the Elorus document. myDATA failure management is handled within Elorus, not Etherly Sync.

​
Manual send

1

Select checkouts

In the dashboard, select one or more checkouts in READY status using their checkboxes.
2

Click «Send»

Use the Send button in the toolbar for bulk sending, or the button next to each checkout for individual sends.
3

Watch the results

Status changes to SENT (success), SENT_WITH_ERRORS (partial), or ERROR (failure). Error messages appear inline on failure.

​
Bulk Send

Select multiple checkouts with checkboxes and click Send Selected to process them in batch.
Bulk sends are processed sequentially (one at a time) to avoid Elorus API rate limits. Allow a few seconds per checkout for large batches.

​
SENT_WITH_ERRORS status

This appears when the invoice and payment receipt were successfully issued, but the Climate Resilience Fee document failed. What to do:
  1. Check the error message in the dashboard
  2. Verify the fee category is correctly configured in Properties
  3. Check that the tax rules in Elorus are current

​
Duplicate prevention

Etherly Sync checks before every issuance whether documents already exist for that checkout. If found, the send is cancelled without error — duplicates are never created.

​
Automatic retries

On failures due to rate limits or temporary Elorus API unavailability, the system automatically retries up to 3 times with exponential backoff. Errors 400/401/403/404 are not retried (they are permanent failures).
