The order arrives by email. Someone types it into the system. Then someone types it again somewhere else.

We are not going to tell you what this is costing you. You have the call log, the calendar and the inbox; the number is yours.
Pick one order from last week. How many times was it typed in before it shipped?
How many hours a week does your office spend copying from an email into the system?
When a typo gets through, who finds it, and how far down the line?
Which spreadsheet does your team keep because the system does not show what they need?
If the person who does the data entry is out sick, what stops?
Most of this is not a new system. It is the systems you already pay for, passing the information along instead of a person doing it.
Purchase orders that arrive by email are read, checked against the customer and the part list, and entered for your team to approve, instead of keyed in by hand.
A new customer, a new job or a changed date is entered once and passed to the CRM, the ERP, the spreadsheet and the calendar that need it.
Order acknowledgements and status updates go to the customer from the record itself, so nobody writes the same email by hand fifty times a week.
Thirty minutes, no charge. We look at how the work runs today and tell you which workflow to automate first. If there is not one, we say so.
