More time passed than I thought it would
I found the billing and payment process a bit more time-consuming than I had anticipated. There was a bit of repeating some steps which felt unnecessary, and I sometimes had to wait longer for confirmation emails to arrive. The invoicing system worked, but it could benefit from speeding up some internal processes. On the positive side, the invoice and payment matched the information discussed earlier, so there weren't surprises there. Overall, it got done, but I did feel the time taken was longer than expected which affected my workflow schedule slightly. It wasn’t terrible, just not as smooth as expected.
