Your invoice consists of five sections:
- Section 1: Previous Advance Estimate
- Section 2: Actual Cost for Services Provided
- Section 3: Summary of Unreturned Dosimeters
- Section 4: New Advance Estimate
- Section 5: Summary of Services
Previous Advance Estimate
This section represents your estimated cost of service as projected in your prior invoice.
Actual Cost for Services Provided
This section provides a breakdown of the actual costs incurred during the prior period. Line items are grouped and subtotaled for every series/subaccount in your account as labeled in the “Series” column. If the series is blank, the associated charges occur at the account level.
The total cost can be found at the end of the section beside the line “Actual Cost For Services Provided.”
Summary of Unreturned Dosimeters
If you select Bill-in-Advance invoicing, you may occasionally see discrepancies between estimated and actual charges. This is often the result of late or unreturned dosimeters.
Returning a dosimeter more than 90 days after the end-date of the assigned monitoring period, or not returning a dosimeter at all, will result in a late/unreturned dosimeter fee. The fee is the result of additional service expenses incurred when dosimeters are returned late or lost.
To avoid these charges, LANDAUER must receive your dosimeters no later than 90 days after the end date of your assigned monitoring period for accounts within the US, Mexico, and Canada. If you are an international client, you have 120 days from the end-date of your service period to return dosimeters.
Note: If you’ve cancelled your service, please return your dosimeters within 45 days of the end-date of your service period or unreturned dosimeter fees will apply.
New Advance Estimate
This section shows how the cost of service for the next billing period is estimated. The total cost can be found at the end of the section beside the line “Total New Advance Estimate.”
Summary of Services
This section combines information from the first four sections and presents the net amount due, which is calculated by adding the balance from the previous invoice to the new advance estimate.
