I have been caught out when sending a lot of invoices to farm focus in the one session i have in the office and I may receive a bounce back email (telling me an invoice needs to be reviewed) but I may not get to the email within that office session, or within the 24 hours before the link to review expires. If the link expires and/or I don't see the email I can easily miss paying a supplier because the invoice has never made it to focus, which has a pretty big impact on our business. I think either the link in the email shouldn't expire after 24 hours, or even better there should be a holding place or an alert in focus that lets me know that invoices have been sent via the scanner but they need reviewing before they are available to code and pay.
