Case Study: How a Customer Portal Cut Status Calls by 75% and Freed 85 Hours/Month
A countertop fabrication shop processing 100 jobs per month implemented SlabWise's customer portal and reduced daily status calls from 12 to 3 within 60 days. The 85+ hours of recovered office time per month translated directly into faster quoting, better follow-up on open leads, and $2,400/month in revenue from jobs that would have been lost to slow response times.
TL;DR
- Shop profile: 14 employees, 100 jobs/month, residential and builder partnerships
- Status calls before: 12 per day (average 8 minutes each)
- Status calls after: 3 per day -- a 75% reduction
- Time recovered: 85+ hours/month of office staff time
- Revenue impact: $2,400/month in additional jobs closed from faster lead response
- Portal adoption: 72% of customers actively using the portal within 60 days
- Implementation focus: Customer portal with automated status notifications
The Shop
Heritage Stone (name changed) is a 14-person fabrication shop in the Southeast that processes about 100 countertop jobs per month. Their customer base is split between direct homeowner sales and builder/contractor partnerships, with builders representing 40% of their volume.
Team Structure
| Role | Headcount |
|---|---|
| Owner | 1 |
| Office Manager | 1 |
| Sales/Estimating | 2 |
| Office Admin | 1 |
| Template Crew | 2 |
| Fabricators | 3 |
| Install Crews | 4 |
| Total | 14 |
The Communication Challenge
With 100 jobs in various stages at any given time, Heritage Stone's office staff spent a significant portion of every day answering the same questions:
- "When is my template appointment?"
- "Has my material been ordered?"
- "When will fabrication start?"
- "What day is my installation scheduled?"
- "Can I see pictures of my slab?"
The office manager, Lisa, described her day: "I'd come in planning to work on quotes and scheduling. By 10 AM, I'd answered 6 calls, and my to-do list hadn't moved."
Measuring the Problem
Before implementing SlabWise, Lisa tracked every incoming call for 30 days. The data confirmed what she already felt.
30-Day Call Log Summary
| Call Type | Daily Average | Avg Duration | Daily Time |
|---|---|---|---|
| Status inquiries (homeowners) | 7 | 8 min | 56 min |
| Status inquiries (contractors) | 3 | 6 min | 18 min |
| Scheduling changes | 1 | 10 min | 10 min |
| New leads/quotes | 3 | 12 min | 36 min |
| Material questions | 1 | 7 min | 7 min |
| Other | 1 | 5 min | 5 min |
| Total | 16 | -- | 132 min (2.2 hrs) |
Status inquiries represented 75% of all incoming calls and consumed about 74 minutes per day. Over a month (22 business days), that's 27 hours dedicated to answering questions that a self-service system could handle.
But the real cost wasn't just the phone time. Lisa and the sales team experienced constant interruptions that fragmented their ability to work on quotes, scheduling, and lead follow-up. The office manager estimated that every status call created an additional 5-10 minutes of lost productivity from context-switching.
Total estimated monthly impact of status calls: 85+ hours of productive time
The Revenue Cost of Slow Response
Heritage Stone tracked their lead-to-quote response time alongside the call data. The results were revealing:
| Lead Response Time | Close Rate |
|---|---|
| Within 1 hour | 42% |
| Within 4 hours | 31% |
| Next business day | 18% |
| 2+ business days | 9% |
Because status calls consumed the first 2-3 hours of every morning, new leads that came in during that window often didn't receive quotes until the afternoon or next day. Lisa estimated that 4-6 leads per month went cold because of slow response times.
At an average job value of $4,800, losing even 3 leads per month to slow response represented $14,400 in missed revenue.
SlabWise Customer Portal Implementation
Heritage Stone implemented SlabWise Standard ($199/month) with the customer portal as the top priority. The full implementation took 18 days, but the portal was active and receiving its first customers by day 10.
Portal Configuration
| Feature | Configuration |
|---|---|
| Branding | Heritage Stone logo, colors, and contact info |
| Status tracking | 8 job stages visible to customers (from "Quote Sent" to "Installation Complete") |
| Automated notifications | Email + SMS at each stage change |
| Scheduling visibility | Template and installation dates shown with time windows |
| Document access | Quotes, contracts, material photos, and approval forms |
| Slab photos | Customers can view photos of their assigned slab before fabrication |
| Messaging | In-portal messaging for non-urgent questions |
Rollout Strategy: Contractors First
Heritage Stone rolled out the portal in two phases:
Phase 1 (Days 10-20): Contractor Partners Builder and contractor accounts were set up first. These partners managed multiple active jobs and generated the most repetitive status calls. Contractor adoption was fast -- within 5 days, 90% of active contractor partners were using the portal.
Phase 2 (Days 20-40): Homeowner Customers Starting with new customers (who received portal invitations as part of the onboarding process), then extending to existing customers with active jobs. Homeowner adoption reached 65% within 30 days.
Automated Notifications: The Biggest Impact
The portal itself was valuable, but the automated notifications drove the most significant call reduction. When a job moved to a new status -- material ordered, slab assigned, fabrication scheduled, fabrication complete, installation scheduled -- the customer received an email and optional SMS notification automatically.
Most status calls were prompted by uncertainty. When customers received proactive updates, the urge to call disappeared.
60-Day Results
Call Volume: 75% Reduction
| Metric | Before | After (60-day avg) |
|---|---|---|
| Daily status calls (homeowners) | 7 | 2 |
| Daily status calls (contractors) | 3 | 0.5 |
| Daily scheduling/other calls | 3 | 2.5 |
| Total daily calls | 16 | 5 |
| Daily phone time | 132 min | 45 min |
Status calls specifically dropped from 10 per day to 2.5 per day -- a 75% reduction. The remaining calls came from the 28% of customers who hadn't adopted the portal and from genuinely complex questions that required human conversation.
Time Recovery: 85+ Hours/Month
| Time Category | Before | After | Monthly Savings |
|---|---|---|---|
| Direct phone time | 48 hrs/mo | 16 hrs/mo | 32 hrs |
| Context-switching losses | 40 hrs/mo | 8 hrs/mo | 32 hrs |
| Call-related follow-up tasks | 22 hrs/mo | 8 hrs/mo | 14 hrs |
| Admin status update prep | 8 hrs/mo | 1 hr/mo | 7 hrs |
| Total | 118 hrs/mo | 33 hrs/mo | 85 hrs/mo |
Revenue Impact: Faster Lead Response
With mornings freed from constant status calls, Lisa and the sales team responded to new leads faster.
| Metric | Before | After |
|---|---|---|
| Average lead response time | 4.5 hours | 1.2 hours |
| Leads quoted same day | 65% | 94% |
| Monthly close rate | 28% | 34% |
| Additional jobs closed/month | -- | ~5 |
| Additional monthly revenue | -- | ~$2,400 (net profit per job) |
Customer Satisfaction Improvement
Heritage Stone surveys customers after installation. Portal-related satisfaction data showed clear trends:
| Survey Question | Before Portal | After Portal |
|---|---|---|
| "Were you kept informed about your project?" | 3.6/5.0 | 4.7/5.0 |
| "How easy was it to reach the company?" | 3.2/5.0 | 4.5/5.0 |
| "Would you refer us to others?" | 78% yes | 91% yes |
| Google review average | 4.3 stars | 4.7 stars |
The paradox: customers felt more informed and accessible after Heritage Stone reduced their actual phone availability, because the portal provided 24/7 self-service access.
Contractor-Specific Benefits
Builder partners saw the most dramatic change. A contractor managing 6 active jobs at Heritage Stone previously called 2-3 times per week for status updates across all projects.
With the portal, that same contractor checks all 6 jobs in a single dashboard login that takes under 2 minutes. The contractor's project manager described it as "the single most useful tool any of our subcontractors have given us."
Contractor Portal Features Used Most
- Multi-project dashboard -- all active jobs on one screen
- Installation scheduling -- see confirmed dates and time windows
- Material photos -- verify slab selection before fabrication starts
- Document access -- download quotes, change orders, and completion certificates
- In-portal messaging -- ask questions without waiting on hold
Financial Summary
| Category | Monthly Impact |
|---|---|
| Additional revenue from faster lead response | +$2,400 |
| Office time savings (valued at $25/hr x 85 hrs) | +$2,125 (in recovered productivity) |
| SlabWise Standard subscription | -$199 |
| Net monthly value | ~$4,326 |
This calculation is conservative. It doesn't include the customer satisfaction improvement (which drives referrals), the contractor relationship strengthening (which drives repeat business), or the reduced stress on office staff.
Implementation Tips from Heritage Stone
1. Launch with Contractors, Not Homeowners
Contractors are tech-comfortable, manage multiple projects, and benefit the most from self-service access. Their quick adoption provides an early win and builds internal confidence.
2. Make the Portal the Default, Not an Option
Heritage Stone includes portal access as a standard part of their customer onboarding. Every new customer receives an invitation. This isn't presented as "if you want" but as "here's how you track your project."
3. Keep Automated Notifications Simple
Lisa's advice: "Don't over-notify. We send updates at key milestones -- material ordered, fabrication starting, installation scheduled. If you send an update every day, people ignore them all."
4. Don't Eliminate Phone Access Entirely
The 25-30% of customers who prefer phone calls should still be able to call. The goal is reducing unnecessary calls, not forcing technology on people who aren't comfortable with it.
FAQ
How long does it take to see call reduction after launching the portal?
Heritage Stone saw a 40% call reduction in the first 2 weeks, growing to 75% by day 60. The improvement tracks directly with portal adoption rates.
What if my customers aren't tech-savvy?
Heritage Stone's customer base skews older in their residential market, and they still achieved 65% homeowner adoption. The portal is simple -- login, see your project status, view your dates. No technical skill required.
Does the portal replace all customer communication?
No. Complex questions, change orders, and sensitive conversations still happen over the phone or in person. The portal handles the repetitive status questions that consume the most time.
Can contractors see pricing information for their projects?
You control what contractors see. Heritage Stone shows status, scheduling, and documents but restricts detailed pricing visibility. Permissions are customizable per account type.
How do automated notifications work?
When your team updates a job status in SlabWise (e.g., moves it from "In Fabrication" to "Ready for Install"), the system automatically sends an email and optional SMS to the customer. No manual notification effort required.
What about customers who don't adopt the portal?
They call, and you answer. The portal doesn't eliminate phone support -- it reduces the volume to manageable levels. Heritage Stone still handles 3-5 phone calls per day from non-portal customers.
Can I customize the portal appearance?
Yes. Your logo, brand colors, company name, and contact information appear on the portal. Customers see a branded experience that looks like your website.
Does the portal work on mobile phones?
Yes. The portal is mobile-responsive and works on any smartphone browser. No app download required.
