Invoice no. not in order

Why invoice no. are not in order??

I need in order to make me easy doing my job.

Hope you can help me.

The order is in date order. I am not sure why you have an invoice on the 16 for invoice 62, but on the 17 you have invoice number 49 and so on. Increment your invoice numbers sequentially and they will show in invoice number order and date order!
