Plumbing Repeat Customer Rate: Use a Clear Definition
Define a repeat customer before calculating the rate. This guide measures customers served in a period who had a completed job before that period began, divided by all distinct customers served during the period. It is not the same as repeat visits, retention, or loyalty.
In this guide
Choose the customer identity you will count
Decide whether a customer means a billing account, a property owner, a household, or another defined entity. Use stable identifiers instead of names alone so a spelling change does not create an apparent new customer.
A property manager with several properties can be one billing account but many service locations. Counting accounts and counting properties answer different questions. State the choice in the report.
Resolve known duplicates or flag uncertainty before drawing conclusions from the rate.
Define the period and prior-work rule
For this calculation, include distinct customers with completed work during the selected period. Count a customer as returning only when that same customer identity had completed work before the period start.
A customer receiving two visits during their first job does not automatically become a returning customer under this definition. Nor does a planned second visit necessarily represent new repeat business.
You may choose another definition, but label it differently and apply it consistently.
Use the returning-customer calculator
Enter the number of qualifying returning customers and the total distinct customers served in the period. Returning customers must be a subset of the total.
In a fictional month with 60 distinct served customers, 18 had completed work before the month began. The returning-customer share is 18 ÷ 60 = 30%.
This does not mean 70% of past customers left the business. Retention requires a different population and observation method; this measure describes the current period's customer mix.
Keep special cases visible
| Situation | Classification question |
|---|---|
| Duplicate customer profiles | Are both records the same defined customer? |
| Property changes ownership | Which customer identity was served? |
| One manager, several properties | Are accounts or service locations the unit? |
| Follow-up on an unfinished job | Is this one job rather than new business? |
| Callback or warranty concern | Should it be separately classified? |
| Incomplete historical migration | Is prior work unavailable rather than absent? |
A missing historical record does not prove a customer is new. Flag incomplete history when it limits the calculation.
Interpret changes with context
A strong new-customer campaign may lower the returning share while adding valuable business. A period with fewer new inquiries may raise the share without improving customer relationships.
Review service mix, seasonality in your own records, and the completeness of the historical dataset. Do not adopt an unsupported percentage target from another business with a different definition.
Turn the review into a useful action
Returning-customer review
Period and customer identity: [definitions]
Total distinct served customers: [count]
Customers with qualifying prior work: [count]
Historical coverage limitation: [notes]
Returning share: [calculation]
Follow-up or data-quality action: [owner/task]
Use the findings to improve service-history accuracy and appropriate customer follow-up, not to send indiscriminate messages. GoPlumber's customer and job records can be assessed as inputs, but verify the exact fields and report availability rather than assuming a native retention dashboard.
