Comeback Prevention for SA Contractors — Save R298,000/Year

The Real Cost of a Comeback

The Panel Status Risk

Beyond the direct cost, comebacks affect your panel standing. A persistent comeback rate above 15% triggers the same review process as SLA non-compliance — informal warning, formal warning, probation, removal. The panel doesn't separate "SLA issues" from "quality issues" in their assessment — both threaten your status.

The 5 Root Causes of Comebacks

1. Rushed Work Under SLA Pressure (35% of comebacks)

The technician has 45 minutes left on a 60-minute SLA. He arrives at the property, assesses quickly, does what he thinks is the problem, and leaves. In 3 days, the customer calls back — same problem, incomplete repair.

The fix isn't to slow down — it's to arrive earlier so there's no pressure. This comes back to SLA strategy: target 30 minutes, not 60. When a team arrives with 30 minutes to spare, they have time to properly diagnose before starting work.

2. Wrong Diagnosis (25% of comebacks)

The geyser element was replaced. The real problem was the thermostat. The customer has cold water again in 2 weeks.

The fix: systematic diagnosis checklists. Before any repair, the technician runs through the full diagnostic — not just the most obvious symptom. PMC's job card includes mandatory checklist items for common job types that must be completed before photos and job close.

3. Cheap or Wrong Materials (20% of comebacks)

A generic Chinese pressure relief valve that fails in 6 months. An incorrect specification element. A rubber washer instead of a ceramic disc in a high-pressure application.

The fix: approved materials list per job type. Pre-stock vans with quality materials that are proven to last. The cost difference between a quality part and a cheap part is typically R50–200. The cost of a comeback is R3,550. The maths is obvious.

4. Incomplete Work (15% of comebacks)

The visible problem was fixed. The underlying cause wasn't addressed. A geyser pressure valve was replaced but the cause of the over-pressure (faulty pressure-reducing valve on the inlet) wasn't identified.

The fix: mandatory photo documentation of the complete repair, including related systems. Photos of what was replaced and photos of the wider context — this forces technicians to look at the full picture, not just the immediate fault.

5. No Testing Before Leaving (5% of comebacks)

Work done. Packed up. Left. The customer turns on the tap and there's still no hot water — the element was installed but the isolator wasn't switched back on.

The fix: mandatory testing checklist before job close. In PMC, the job card cannot be marked complete without confirming specific tests were performed — geyser heated (check), power restored (check), pressure normal (check), customer shown operation (check).

The Prevention System

1. Mandatory Photo Evidence (Before and After)

Photos serve two purposes: accountability (the technician must actually look at what they're photographing) and protection (evidence for disputes). In PMC, a minimum number of photos is required before a job can be closed. No photos = can't close the job. No override.

The side effect of mandatory photos: technicians who know they have to photograph the repair tend to do better work. It's not about catching failures — it's about creating the moment of accountability before leaving the site.

2. Digital Checklists Per Job Type

A geyser replacement has a different checklist than an electrical DB board repair. Each job type in PMC has a configured checklist — required fields that must be completed before close. Diagnosis steps. Materials used. Tests performed. Customer confirmation received.

This isn't bureaucracy — it's the difference between a technician who finishes a job because it's done, and one who finishes because the system confirmed it's done.

3. Customer Sign-Off Before Technician Leaves

The customer signs (digitally, in the PMC app) that the work is complete and they're satisfied. This does two things: it creates a record that prevents "I was never satisfied" disputes, and it forces the technician to demonstrate the repair to the customer before leaving — which catches "I forgot to switch the isolator back on" issues on the spot.

4. Materials Tracking

Every material used is logged in the job card — brand, specification, quantity. This creates an audit trail for warranty work and allows analysis of which materials generate the most comebacks. Within 3 months you'll know which brands and specs to remove from your approved list.

5. Comeback Tracking and Root Cause Analysis

Every comeback is logged in PMC with a cause category. Monthly report: which job types have the highest comeback rate, which teams, which materials. This turns comeback prevention from reactive (responding to problems) to proactive (fixing the patterns before they accumulate).

The ROI: From 10% to 3% Comeback Rate

AI Reports — Catching Issues Before the Job Closes

PMC's AI add-on (R199/month on Panel Pro) includes compliance verification before job close — the AI checks that all required fields are complete, photos meet minimum requirements, the COC is attached if required, and the customer has signed off. It flags gaps before the technician leaves the site, not after the insurer reviews the claim.

It also generates the professional job report from the field data — formatted for insurer submission, with grammar and professionalism checked. Reports that look professional create fewer disputes and process faster through the insurer's system.
