What Happens After You Order? Parts order
Step 1 Email confirmation
After checking out or requesting a quote, you will receive an email confirming that we have received your order. Your quote will be accepted or your web order will be placed.

Step 2 Dedicated customer service rep
One of our customer service reps will be in touch to verify your part(s) and confirm your shipping details.

There's also a principle running through everything amikon does that doesn't show up on a spec sheet: if a customer can't find their part anywhere else, the team will track it down. No dead ends. That's a promise, not a marketing line.

If your line is down or you're trying to source a part that everyone else has given up on, the story continues. So does the search.
