Key takeaways
- A call becomes billable when it passes a minimum duration (often 60, 90, or 120 seconds depending on the vertical) or shows clear buying intent before that mark.
- Repeat callers within a set window are not billed twice, because the same customer should only be paid for once.
- Calls that ring during your posted hours are your responsibility to answer. Missed calls are the most common source of avoidable spend.
- Disputes are decided on the recording and call data, and most programs give you a limited window to file, so review your call log weekly at minimum.
- Recordings exist to settle disputes fairly and to help you coach your team, not to trap you.
What does billable mean in pay-per-call?
In pay-per-call you do not pay for clicks, impressions, or the phone ringing. You pay for a delivered call that meets the program's written definition of a real opportunity, agreed before calls start. Every rule below exists to answer one question: was this a genuine prospect for your service, in your area, that you had a fair chance to win?
Both sides need the rules to be clear. Without them, every invoice becomes an argument.
How does minimum duration (buffer time) work?
The most common rule is a minimum call duration, sometimes called buffer time. A call shorter than the threshold is not billed. Typical thresholds are 60, 90, or 120 seconds, and the right number depends on the vertical.
- Emergency home services such as plumbing, locksmith, or towing often use shorter buffers, because a real customer states the problem and location quickly
- Legal, insurance, and financial verticals often use longer buffers, because a real intake conversation takes time to reach a meaningful point
- Very short calls (wrong numbers, hang-ups, pocket dials) fall below any buffer and are not billed
- The buffer typically starts when the call connects to your line, so hold time or a long phone tree on your side counts against you
The buffer is not a promise that every call over the threshold is a great lead. It is a filter that removes the obviously worthless calls automatically, so that disputes can focus on the calls that need a human look.
Can intent make a short call billable?
Yes, in many programs. If a caller clearly asks for a quote, a price, or an appointment, and you turn them away or the call ends before the buffer, the call may still be billable because the intent was there. The provider delivered a customer who wanted to buy.
The reverse also applies. A call that runs past the buffer but turns out to be a vendor pitch, a job seeker, or a request for a service you do not offer can be disputed and credited, because duration without intent is not a lead.
The practical lesson: train whoever answers your phone to keep a real prospect on the line, gather the details, and book. Hanging up quickly on a live prospect can cost you the job and the call fee at the same time.
Why are duplicate callers not billed?
If the same phone number calls you again within the duplicate window, 14 days in this program, the second call is not billed. You paid for that customer once. Follow-up calls, callbacks, and a customer confirming an appointment are part of the same opportunity.
Check how your program defines the window and whether it is measured by phone number, since a customer who calls from a second phone may register as a new caller. If you see the same household twice, flag it. The recording will usually make the connection obvious.
What happens to calls you miss during posted hours?
You set the hours during which you can receive calls, and calls are only routed to you inside those hours. If a call rings during your posted hours and nobody answers, most programs treat it as delivered, because the advertising was purchased and the customer was on the line. Rules vary on voicemail and ring time, so read your program's guidelines on missed calls specifically.
Missed calls are the most avoidable source of wasted pay-per-call spend. If you cannot answer reliably from 7am to 9pm, do not post 7am to 9pm. Post the hours you can staff, use a rollover number or an answering service that can book for overflow, and watch your answer rate in the portal every week.
How do you dispute a call, and how fast do you need to act?
A dispute is a request to have a specific call reviewed and credited. In a portal-based program, you open the call in your call log, listen to the recording, select a reason, and submit. Common valid reasons include wrong service, out of service area, duplicate, spam or solicitation, and no intent.
Programs set a dispute window, often a few days from the call, and calls outside the window are considered accepted. The window exists so that both sides are working from fresh data. The habit that protects you is simple: review your call log at least weekly, and daily when you are new to the program.
Two things make disputes go smoothly. First, be specific. 'Caller asked for commercial roofing, we do residential only' is easy to verify. Second, do not dispute good calls you failed to close. A prospect who got a quote and chose someone else was a real call, and disputing it costs you credibility.
What are the recordings for?
Recordings are the evidence layer. They let the provider verify a dispute without taking either side's word for it, and they let you check what your team actually said. Most owners who listen to a week of their own recordings find at least one thing to fix: a slow greeting, a missed chance to book, a price quoted too early.
Recordings also protect you against an unfair denial: if the recording shows a vendor pitch, the credit should follow. Where recordings are used, callers are notified in line with applicable law, which we cover in our guide to TCPA and consent.
How do you get the most value out of the rules?
The rules define a fair trade. The buyers who do best treat them as an operating checklist.
- Read the billable call guidelines for your vertical before your first call, and ask about anything unclear
- Post hours you can actually staff, and track answer rate weekly
- Train your team to keep real prospects talking, gather details, and book on the call
- Review the call log and file disputes within the window, with specific reasons
- Listen to recordings monthly for coaching, not only for disputes
Frequently asked questions
What is buffer time in pay-per-call?
Buffer time is the minimum call duration before a call is billable, commonly 60, 90, or 120 seconds depending on the vertical. Calls shorter than the buffer are not billed unless clear intent was shown.
If a call is longer than the buffer, do I always pay?
Not necessarily. A long call with no intent, such as a solicitation or a request for a service you do not offer, can be disputed and credited.
Are repeat callers billed again?
No. Calls from the same number within the program's duplicate window, 14 days in this program, are not billed a second time.
How long do I have to dispute a call?
It depends on the program, but windows are usually measured in days, not weeks. Review your call log at least weekly so nothing expires.
