APRIL 2026 — CONSUMER BILL AUDIT EDITION — DIGITAL SIGNET
Case studies: what a real audit saves (consumer, SMB, mid-market).
By Oliver, Digital Signet — Last verified April 2026
10 min readThe following three case studies are anonymised but specific. Dollar amounts, app counts, and savings percentages reflect real audit outcomes. They are presented here to illustrate the methodology and set realistic expectations. The mechanism is identical across all three scales: a systematic line-item audit, followed by targeted rationalisation and negotiation, followed by a quarterly review to prevent creep from returning.
Case Study 1 of 3
Household audit: family of four
$847/mo
Starting monthly spend
$523/mo
After audit
$3,888/yr
Annual saving
Starting position
A family of four in a major US metro. Monthly bill burden: Verizon 4-line plan ($212/mo after all surcharges), Xfinity internet + TV ($187/mo after fees), Netflix Premium + Disney/Hulu/Max bundle + Apple TV+ + Peacock ($107/mo), Microsoft 365 Family + iCloud 2TB + Adobe Lightroom ($52/mo), Peloton All-Access + Planet Fitness + Headspace + MyFitnessPal ($97/mo), phone insurance x2 ($34/mo), extended home warranty ($60/mo), AAA ($12/mo), credit card annual fees ($25/mo). Total: $847/month.
Audit findings and actions
| Item | Action | Saving/mo |
|---|---|---|
| Verizon 4-line plan | Retention call with T-Mobile quote. Received $45/mo loyalty credit for 12 months. | $45/mo |
| Xfinity TV package | Cancelled TV, kept internet only. Moved to YouTube TV ($72.99) for live channels. | $38/mo |
| Netflix Premium | Downgraded to Standard ad-free ($17.99). Don't need 4K on all screens. | $7/mo |
| Apple TV+ + Peacock | Cancelled both. Rotate Peacock for specific shows; Apple TV+ was barely opened. | $18/mo |
| Peloton All-Access | Downgraded to Peloton App ($12.99/mo). Bike retained; all-access tier was overkill. | $31/mo |
| Planet Fitness (second adult) | Cancelled. Second adult uses Peloton app exclusively. | $25/mo |
| Headspace | Cancelled. Free Insight Timer covers the same content. | $13/mo |
| Phone insurance (2 phones) | Cancelled on both devices (3+ years old, low replacement value). | $34/mo |
| Extended home warranty | Cancelled after reviewing 3-year claim history. Zero claims; repair costs over 3 years: $0. | $60/mo |
| AAA | Kept. Verizon roadside is free but AAA Trip Planning justifies retention. | $0/mo |
Total monthly saving: $324/mo. Annualised: $3,888. Time invested: 6 hours (audit and calls). Recurring effort: 2-hour annual review.
Case Study 2 of 3
SMB SaaS audit: 45-person services firm
$412k
Annual SaaS spend
$288k
After audit
$124k (30%)
Annual saving
A 45-person professional services firm (consulting, post-Series A). SaaS portfolio of 87 applications discovered during the audit (45 through central IT, 42 through shadow IT via team interviews and AP records). Annual SaaS spend of $412k represented $9,156 per employee per year, above the Zylo benchmark of ~$5,000-$7,000 for this company size.
29 applications cancelled
22 with under 10% seat utilisation, 7 with zero active users in 90 days. Saved $84k/yr.
12 applications downgraded
Moved from enterprise to standard or team tier based on actual seat needs. Saved $22k/yr.
4 contracts renegotiated
Two project management tools, one analytics platform, one CRM. Used competitive quotes and RFP threat. Saved $18k/yr.
Total saving: $124k/yr (30% reduction). Shelfware rate: 47% by application count (consistent with Zylo's 53% benchmark). Time: 60 days of intermittent effort. Implemented Torii for ongoing SaaS governance.
Case Study 3 of 3
Mid-market cloud audit: $180k/mo AWS bill
$180k/mo
Monthly cloud spend (before)
$124k/mo
After 90-day audit
$672k/yr (31%)
Annualised saving
A mid-market SaaS company (500 employees, 3 AWS accounts). Cloud bill had grown from $80k/month two years prior without a corresponding FinOps review cycle. Reserved Instance and Savings Plan coverage had lapsed 14 months earlier; the entire stable compute workload was running at on-demand pricing.
1-year Compute Savings Plans at 75% coverage
Purchased $85k/mo in Compute Savings Plans at 75% of stable compute baseline. Average discount: 38% over on-demand. Monthly saving: $32k.
EC2 instance right-sizing via Compute Optimizer
22 instance types identified as over-provisioned; 15 resized. Average utilisation before: 12%. After: 48%. Monthly saving: $14k.
S3 Intelligent-Tiering and lifecycle policies
3.2PB of S3 Standard storage; 60% classified as infrequent access after Intelligent-Tiering analysis. Transition to IA saved $4k/month.
Orphaned resource cleanup
47 unattached EBS volumes, 312 stale snapshots, 8 unused Elastic IPs. One-time cleanup and ongoing governance. Monthly saving: $6k.
Total saving: $56k/mo = $672k/yr (31% reduction). Consistent with the FinOps Foundation's 27% average plus aggressive right-sizing effort. Implemented Vantage for ongoing FinOps monitoring. Weekly 30-min FinOps review established.
The common pattern
All three cases share the same structure: discovery (what are we paying for?), utilisation audit (are we using it?), rationalisation (cancel, downgrade, or negotiate), and ongoing review (quarterly check to prevent re-accumulation). The dollar scales differ by two orders of magnitude. The mechanism is identical. The household and the mid-market company are the same problem at different sizes.
The single most important variable in all three cases was not the dollar amount or the number of applications. It was whether a named person owned the renewal calendar. In all three cases, the review cadence established at the end of the 90-day project has been maintained 12 months later, and the savings have persisted.

How much can a household realistically save from a bill audit?+
The household case study documents a family of four who reduced monthly bill burden from $847 to $523 per month, saving $324/month or $3,888 per year. The largest savings were from negotiating Verizon ($45/mo), cancelling unused streaming and software ($89/mo combined), and removing unused gym and wellness subscriptions ($70/mo).
What does a 30% SaaS reduction look like in practice?+
The SMB case study documents a 45-person firm with $412k annual SaaS spend. After 60 days, 29 apps cancelled, 12 downgraded, 4 renegotiated. Total saving: $124k/year (30%). The firm's shelfware rate was 47% of applications by count, consistent with the Zylo 2026 benchmark of 53%.
Is a 31% cloud cost reduction realistic in 90 days?+
Yes, particularly for accounts that have lapsed Reserved Instance or Savings Plan coverage. The cloud case study reduced a $180k/month AWS bill to $124k/month (31% reduction) primarily through purchasing Savings Plans for stable compute (saving $32k/mo), EC2 right-sizing ($14k/mo), S3 lifecycle policies ($4k/mo), and orphaned resource cleanup ($6k/mo).
Do the savings persist after the first audit?+
Yes, if a quarterly review cadence is implemented. Without ongoing review, creep returns. All three case studies implemented quarterly reviews, and savings have been maintained 12 months later with incremental 8-12% reductions in year two.
