Agree on what each stage means.
Keep inquiries, qualified opportunities, estimates, booked work and collected revenue distinct. A form submission is not a booked job. An accepted estimate is not necessarily collected revenue.
Choose definitions the people answering calls and preparing estimates can apply consistently. An inquiry might be qualified only after the requested service, territory and project fit are confirmed. Record the reason when it is not a fit.
Capture enough context to act.
A useful inquiry record includes when it arrived, how to respond, the requested work, service location, known source and responsible person. Only collect information needed for the job. Avoid storing sensitive customer information in loosely shared spreadsheets.
Source attribution is often incomplete. A customer may see an ad, read reviews and later call directly. Preserve the known evidence rather than forcing every inquiry into an artificially precise source.
Give each inquiry an owner and a next step.
Assign responsibility for responding and updating the status. A record without an owner can make a report look complete while the customer waits. Record the next action and any agreed follow-up date.
Keep missed calls, duplicates, spam and out-of-area inquiries separate from useful opportunities. This helps distinguish a demand problem from a response problem.
Reconcile marketing activity with business records.
Review a manageable set of inquiries against estimates and job records. Record wins, losses and unknown outcomes honestly. Where customers or projects appear more than once, resolve duplicates before counting them.
Use actual collected revenue when discussing collected revenue. If you use estimated contract value, label it that way. Do not count one customer multiple times simply because several tools recorded the interaction.
Use the review to change a decision.
Look for patterns in service type, location, inquiry quality and response. If a campaign attracts work you do not want, change the targeting or offer. If suitable inquiries stall before an estimate, investigate that handoff.
Start with a system the team will maintain. ACS helps define the stages, connect useful records and choose tools that reduce repeated work. You get a practical review process that supports decisions without adding unnecessary administration.
