It is possible to set approval limits for users. This gives you the option to limit or extend permissions as you envisage. You can find this option in the user settings.
Limits relate to invoice amounts. If you do not have enough limit, you will not be able to check or approve the invoice.
Setting these limits can be done in two ways:
1. By administration
If you set the limits per user by administration then you can set a different approval limit for each administration. For example, user A can approve up to 5,000 euros for Administration 001 and up to 300 euros for Administration 002.
2. Based on invoice type and administration
If you set the limits based on invoice type and administration, you can also set a limit per administration specifically for cost or goods invoices.
