Why manufacturers still use Excel for this
Customer complaints are the highest-signal quality data any manufacturer gets — and the most underused. A customer who complains is telling you exactly what they care about, where you are failing, and (usually) what would satisfy them. Most shops respond, resolve, and forget. The pattern across complaints is the gold.
This template forces structure on complaint capture: severity (does it affect safety, ship date, or just convenience?), category (defect, delivery, billing, service), root-cause linkage, resolution date, and customer satisfaction follow-up. Each field exists because dropping it costs information.
After 90 days of disciplined logging, the Pareto by category and root cause is unmissable. Most shops discover that 60–70% of complaints concentrate in 3–4 patterns — fix those and complaint volume drops dramatically. The template makes that analysis trivial.
What's inside the template
Complaint event log
Date received, customer, complaint number, category, severity, description, owner, target resolution date, status.
Severity classification
Critical (safety/recall), High (ship-affecting), Medium (quality variance), Low (convenience). Each has an SLA for response.
Root-cause linkage
Every complaint requiring CA gets linked to the corrective action log. The link column tracks whether RCA was actually done.
Resolution tracker
Resolution date, what was done, customer-confirmed acceptance. Open complaints aging beyond SLA are flagged red.
Customer satisfaction follow-up
Post-resolution check: did the customer report the resolution worked? Most shops skip this step and miss the most important data point.
Pareto and trend
Complaint count by category and root cause, with 12-month rolling trend. The picture that drives improvement priorities.
How to use this template
A practical walkthrough, from the sample data to a plan built on your own numbers.
- 1
Capture every complaint, not just formal ones
A customer who calls and says "this part was off" is a complaint event, even without a formal complaint form. The template captures informal complaints separately so you do not under-count.
- 2
Acknowledge within SLA
Critical: same day. High: 1 business day. Medium: 3 days. Low: 5 days. The SLA column tracks acknowledgment date vs SLA. Late acknowledgments compound the original complaint.
- 3
Force a root cause for repeat complaints
If the same customer complains about the same issue twice, no root cause analysis = system failure. The template flags repeat complaints automatically.
- 4
Follow up after resolution
A complaint is closed only when the customer confirms the resolution worked. "We sent them a replacement" is not a closed complaint — "the customer received the replacement and accepted it" is.
When you outgrow this template
Excel is the right answer for early-stage planning, until it isn't. These are the warning signs that you need a real production scheduling tool.
If three or more of these apply, you have outgrown spreadsheet planning. EDGEBIC, the current generation of RMDB, is User Solutions' finite capacity scheduling and production planning software. It imports the same orders, routings, work centers and stock from Excel, CSV or your ERP, schedules them against real machine, labor and material limits, and shows the result on a drag-and-drop Gantt chart. It is a one-time license: EDGEBIC APS is $25,000, and EDGEBIC Complete, which adds MRP, inventory and purchasing, is $35,000.

Frequently asked questions
What counts as a "complaint" for tracking purposes?+
Any expression of dissatisfaction by a customer about the product, service, or relationship. Informal complaints (a phone call) count as much as formal ones (an email or returned material). The template captures both — formal complaints are higher signal but informal ones surface earlier.
How do I separate complaints from returns?+
Returns are a transaction; complaints are a quality event. A return that includes a complaint about quality is both — log the return in your ERP and the complaint in the tracker. A return for "wrong size ordered" without quality issue is not a complaint.
Should every complaint trigger a corrective action?+
No. One-off complaints with no recurrence pattern usually do not need a formal CA. Repeat complaints (same root cause, multiple customers) absolutely do. The Pareto chart makes the distinction visible.
How long should I keep complaint records?+
Industry-specific. ISO 9001 minimum is typically 3 years. Medical devices require lifetime of device + 2 years. FDA-regulated industries require GMP retention. Check your specific compliance requirements.
Start with the spreadsheet. Move to EDGEBIC when it breaks.
The template handles the math for a small plan. EDGEBIC is what manufacturers move to when orders, routings and capacity change faster than a spreadsheet can follow: published one-time pricing, and implementation measured in days.
