I have noticed that in my Orders grid in the admin, all the(hundreds) of orders have sequential order ids, all but one. I have 100000103 and then 100000105.
The 100000104 is missing. I have checked this post(magento order id increment jumps) on StackOverflow, but the answer there suggests the following:
If you want to find your 'missing' increment_ids, take a look in sales_flat_quote under the field reserved_order_id. You should see them attached to unconverted quote objects (carts). But I do not have the missing ID in the specified table for the reserved_order_id column. It is also missing from there, the IDs go 103 and then 105..
I have also checked the abandoned carts reports grid, it is empty. Should I be concerned that there was some error? The shop owner says he is worried that some order is missing or something..
