Is Plumbing Automation Worth It? Count the Completed Work.

Short answer: compare a measured baseline with a limited pilot. Count additional completed jobs you can attribute to the new workflow, add any genuinely freed staff time, then subtract software, setup, review and operating costs. A missed call is an opportunity, not booked revenue.

Use your call logs, job records and invoices

Before changing the phone or quoting workflow, record:

• Incoming calls by time of day; answered, missed and returned calls.
• How many enquiries became qualified jobs, approved quotes, bookings and completed invoices.
• Time spent on call notes, quote preparation, scheduling and corrections.
• Average contribution after direct job costs, and whether the team has capacity for extra work.

Job software, phone logs and invoices may hold different versions of the same enquiry. Deduplicate them before drawing conclusions.

Work from contribution after job costs

Incremental contribution = additional completed jobs attributable to the pilot × average contribution per completed job. Use contribution after direct materials and labour costs, not the full invoice value. Then subtract the pilot's software, setup, call handling, review and support costs.

Time capacity = measured time freed from routine admin − time spent reviewing, correcting and maintaining the system. Do not add the value of those same hours again as revenue if they were already used to complete the incremental jobs.

Test one task and inspect the awkward cases

Choose one task, such as capturing missed-call details or preparing quote drafts. Agree who checks it, who handles urgent or unclear cases and which period you will compare. Inspect records for incorrect urgency, missing details, unchecked prices and customer confusion. Discuss the results with the people doing the work.

If additional enquiries arrive but the team cannot fulfil them, improve scheduling or capacity before counting them as growth. If quote drafting is faster but creates more corrections, include that review effort in the cost.

Ask for the practical details and full running cost

• What systems and permissions are needed? How are failures and out-of-hours alerts handled?
• Who checks quotes, technical statements and customer messages before they go out?
• What are the actual setup, usage, support and exit costs for my workflow?
• Which records will show whether the pilot helped customers and staff?
