DuemendTerms of service
Updated 25 October 2026. Duemend is provided by Samet Ateşen, trading as Atesen Software, Sakarya, Türkiye. Support: support@atesensoftware.com.
Using the service
You must have authority to access and edit the connected organisation. Review the selected invoices, date field and preview before confirming UPDATE n. You remain responsible for accounting accuracy and legal recordkeeping.
Duemend writes only after you type the confirmation, and only to the organisation you chose. Xero can reject a date change (for example in a locked period); its ValidationException message appears on the affected row.
Undo restores stored old dates on successful rows for 30 days. A date changed again since the update is skipped, so a later edit is preserved. Xero cannot clear a date again, so a date that was empty before the update stays in place; the preview says how many invoices this affects.
Access and payment
Load and Preview are free. Your first 10 successful rows per organisation are free, with no trial expiry. Maximum 1,000 rows per job; write calls contain at most 50 invoices. Reads above 10,000 invoices fail clearly without showing a partial list. A pass costs $19 for 7 days; monthly access costs $12/month, excl. VAT/sales tax. Prices exclude VAT and sales tax. Where tax applies, Paddle adds it at checkout and shows the total before you pay. Paddle handles payments and its buyer terms also apply. Monthly access renews until cancelled through Manage subscription. Cancellation preserves access until the paid period ends.
Availability and responsibility
Xero availability, permissions and rate limits can delay or refuse updates. We do not guarantee that every date change will be accepted. Do not resubmit uncertain rows without checking their result in Xero. Keep independent records. Nothing here removes mandatory consumer rights or liability that cannot lawfully be excluded.
Ending access
Use Disconnect to revoke local access and delete saved invoice details, or Sign out to end the session. Refunds are described on the refunds page. Material service or term changes will be communicated through the service or the account contact.
