What the Export Amount selector does
The Export Amount has two options: Net and Total. This setting tells Datamolino which amount to treat as the anchor for the document - the value that stays fixed while the other amounts are calculated around it.
The Export Amount setting is located above the checksum in document detail:
👉 Does Datamolino pick this for me?
Yes. Datamolino tries to automatically select the correct value (Net or Total) based on what it read from the document. In most cases the auto-pick is right and you do not need to touch it. In rare cases you may need to switch it manually so that recalculation works the way you expect.
Which amount stays constant when you edit
This is the part that catches people out. The Export Amount you choose becomes the anchor. When you edit the document or change the tax code, the anchor value stays exactly where you put it, and the other amounts (Net, Tax, Total) recalculate around it.
If Total is selected, Total stays constant. Net and Tax recalculate to match.
If Net is selected, Net stays constant. Tax and Total recalculate to match.
This matters most when you are correcting amounts. If the wrong anchor is selected, your edits will recalculate the wrong values - and the number you wanted to keep fixed will shift.
👉 Can you walk me through an example?
Say a document has a true Total of 120 and Datamolino captured the total incorrectly as 118. You switch the Export Amount to Total, manually edit the Total to 120, then select the correct tax code. Net and Tax now recalculate from that fixed 120 - so the figures match the real invoice.
If the Net is the value you trust (for example, you have a Net of 100 and a tax rate you want to apply), set Export Amount to Net, type 100 into the Net field, and pick the tax code. Tax and Total are calculated from the 100, and 100 stays put.
How Net vs. Total affects Xero exports
For folders connected to Xero, the Export Amount setting also decides how line amounts are sent:
Net exports amounts as tax exclusive.
Total exports amounts as tax inclusive.
👉 Will the invoice look different in Xero depending on which I pick?
No. Once the invoice is approved in Xero, it is displayed as tax-exclusive either way - Xero recalculates and re-displays the amounts for you. The Export Amount setting controls how Datamolino sends the values; Xero handles the final display.
👉 So why does the toggle matter for Xero users?
Because it still controls which amount stays constant in Datamolino while you are reviewing and editing the document. If you trust the Total on the supplier invoice, set the anchor to Total before exporting so the figures Xero receives match the paper invoice exactly.
