In a job shop the estimator is usually also the programmer, the setup person or the owner. RFQs wait for a gap in the day, and quotes go out with nobody assigned to chase them.

RFQs arrive by email with drawings attached, sometimes to the wrong inbox. Someone has to notice them, tell the customer they arrived, get them to whoever quotes, and then remember to follow up. The quoting is skilled work. Everything around it is the part that gets dropped.
The skilled part stays with your estimator. Everything around it, the logging, the acknowledgement and the chasing, stops depending on somebody remembering.
We are not going to quote you a statistic about your industry. Open your inbox and answer these.
How many RFQs came in last month, and how many got an answer the same day?
Where is the list of every quote you have out right now?
How many quotes did you send last quarter that nobody followed up on?
When a customer asks about a quote from three weeks ago, how long does it take to find it?
One package, built around how your shop quotes today.
Every RFQ is logged automatically, and the customer gets an acknowledgement within minutes saying it arrived and when to expect a quote.
Every open quote on one list, so nothing sits forgotten in an inbox.
Unanswered quotes are followed up automatically at 3, 7 and 14 days, in your words, until the customer answers or says stop.
Once a quote becomes an order, status updates can go to the customer from your ERP or your spreadsheet.
Best fit: a job shop or machine shop that quotes every week and has no one whose whole job is chasing quotes.
We find the one workflow worth automating first. If there is not one, we say so.
