A simple quality assurance process answers both questions. Here is how to build one.
1. Record Every Call Automatically
You can’t review what you haven’t captured. Asking agents to record calls by hand fails, because they forget or skip the difficult ones. The reliable approach is automatic capture. Qualitify, a WhatsApp call recording and quality assurance software built for this purpose, records calls from a desktop app and organises them by agent, date and direction so managers can find any conversation quickly.
Be open about it. Tell your agents that calls are recorded, and ask customers for consent where the law requires it, since rules differ by country.
2. Review a Fair Sample
No team can review every call. The goal is to review enough calls, chosen fairly, to get an honest picture. Avoid reviewing only the easiest calls to find, such as the longest or the most recent. That leaves some agents almost never reviewed and skews your results.
A sampling policy that spreads reviews across the whole team gives each agent comparable coverage. It also lets you explain why any given call was selected.
3. Score Against Your Own Criteria
A good scorecard reflects what matters to your business. Most teams start with a handful of criteria:
-
Communication: clear opening, polite tone, active listening
-
Accuracy: correct prices, products and policies
-
Resolution: the customer’s issue is solved or moved forward
-
Professionalism: courtesy and patience
-
Closing: a confirmed next step
Weight the criteria by importance, and define serious mistakes that fail a call outright, such as quoting the wrong price. Timestamped notes make feedback concrete: “At 04:38 you could have offered the replacement sooner” teaches far more than “handle complaints better.”
4. Measure Performance, Not Just Activity
Call volume shows how busy someone was, not how well they did. Report talk time and call counts beside review coverage and average score. Two rules keep the numbers honest:
-
Show how many reviews sit behind each average. A score from five reviews is not as solid as one from forty.
-
Never count an unreviewed call as a zero. It is a gap in coverage, not a failure.
Daily call goals for each agent add another layer, letting everyone track progress through the day.
5. Turn Scores into Coaching
A score alone changes nothing. Improvement comes from a plan that names the skill to work on, the supervisor who owns it, and a date to follow up. When that date arrives, compare reviews from before and after the plan. If an agent’s closing score rises from 7.4 to 8.6 across several reviews, you have evidence the coaching worked. If it doesn’t move, change your approach.
6. Protect Privacy and Trust
Agents engage with QA when they trust how recordings are handled. Good practice includes deleting audio automatically after a fixed period, keeping scores and notes after the audio is gone, keeping each company’s recordings strictly separate, and never using recordings to train AI models.
Getting Started
You don’t need a big team or budget. Start with a few criteria, review a handful of calls per agent each week, and build the habit before scaling up. To see how recording, review, reporting and coaching fit together in Qualitify, see it in action with the live demo.
Final Thoughts
WhatsApp calls hold some of your most important customer conversations. By recording them automatically, reviewing a fair sample, scoring against clear criteria and attaching coaching plans to the results, you turn invisible conversations into measurable improvement. Teams that follow a consistent WhatsApp call quality assurance process spend less time guessing and more time developing agents who deliver better service.
