Payment Tool Stack by Volume Tier
Most SMBs either buy tools too early (waste money) or too late (damage is done). This guide tells you exactly what tools to use at each volume tier and when to upgrade.
The answer changes based on your monthly volume and chargeback ratio.

The Question This Answers
"Should I buy [fraud tool X] at my volume?"
Wrong answer: "It depends on your business" Right answer: Specific guidance by volume and CB ratio
At $50K/month with 0.4% CB ratio: No, use processor built-ins. At $500K/month with 0.8% CB ratio: Yes, buy fraud tool immediately.
Tool Stack Progression
Key insight: Add tools as revenue justifies cost, not because they're "best practice."
Under $50K/Month: Processor Built-Ins Only
What to Use
| Tool Category | Recommendation | Cost |
|---|---|---|
| Processor | Stripe or Square | 2.9% + $0.30 |
| Fraud detection | Stripe Radar (free) or Square built-in | $0 |
| Chargeback management | Manual via processor dashboard | $0 |
| Analytics | Processor dashboard | $0 |
| Refunds | Manual via processor | $0 |
Total monthly tool cost: $0-50
What NOT to Buy Yet
❌ Third-party fraud tool ($500-2K/month) - ROI doesn't justify at this volume ❌ Chargeback alerts ($300-1K/month) - Won't hit 75 CB/month threshold anyway ❌ Dedicated analytics ($200-500/month) - Processor reports sufficient ❌ Manual review service ($1-3K/month) - You can review manually
Why
Math check:
- $50K/month, 0.5% CB ratio = 8 chargebacks
- Dispute alert service: $300/month
- Would prevent: ~3 chargebacks (40%)
- Savings: 3 × $85 = $255
- Cost: $300, Saves: $255 = Lose $45/month
Not worth it yet. Use free tools until volume justifies paid tools.
$50K-$250K/Month: Add Dispute Alerts
What to Use
| Tool Category | Recommendation | Cost |
|---|---|---|
| Processor | Stripe or Square | 2.9% + $0.30 |
| Fraud detection | Stripe Radar or Square | $0 |
| Dispute alerts | Verifi (Visa) + Ethoca (Mastercard) | $200-600 |
| Chargeback management | Manual via dashboard | $0 |
| Analytics | Processor dashboard | $0 |
Total monthly tool cost: $200-600
When to Add Dispute Alerts
Add when you hit:
- 75+ chargebacks/month (Visa RDR threshold) OR
- 0.6%+ chargeback ratio (approaching monitoring programs)
At $150K/month, 0.6% CB ratio:
- ~23 chargebacks/month
- Dispute alerts prevent: ~9 (40%)
- Cost: $300-400/month
- Saves: 9 × $85 = $765
- ROI: $400 cost, $765 saved = +$365/month profit
This is when dispute alerts become profitable.
Where to Buy
| Service | Networks | Cost | How to Buy |
|---|---|---|---|
| Verifi (CDRN) | Visa, Discover | $150-400/mo | Through processor or direct |
| Ethoca | Mastercard | $150-400/mo | Through processor or direct |
| Stripe RDR | Visa only | Free (included) | Auto-enabled in Stripe |
If on Stripe: RDR is free. Add Ethoca for Mastercard ($200-300). If on Square: Buy Verifi + Ethoca separately ($400-600).
What Still NOT to Buy
❌ Third-party fraud tool - Stripe Radar or Square still sufficient ❌ Manual review service - You can still review flagged orders yourself ❌ Chargeback guarantee - Too expensive at this volume
$250K-$1M/Month: Add Fraud Tool
What to Use
| Tool Category | Recommendation | Cost |
|---|---|---|
| Processor | Stripe (negotiate rates) | 2.7-2.9% + $0.30 |
| Fraud detection | Sift, Signifyd, or Forter | $800-3,000 |
| Dispute alerts | Verifi + Ethoca | $400-800 |
| Chargeback management | Chargeflow or manual | $0-500 |
| Analytics | Processor + basic BI | $0-200 |
Total monthly tool cost: $1,200-4,500
When to Add Fraud Tool
Add when:
- CB ratio >0.7% despite basic fraud prevention OR
- Processing >$500K/month OR
- High-risk industry (digital goods, supplements)
At $500K/month, 0.8% CB ratio:
- ~40 chargebacks/month
- Fraud tool prevents: ~12 (30%)
- Cost: $2,000/month
- Saves: 12 × $90 = $1,080 + keeps you under 0.9% threshold
- ROI: Prevents VAMP enrollment = priceless
Fraud Tool Options
| Tool | Best For | Cost | Strengths |
|---|---|---|---|
| Sift | General e-commerce | $1K-3K | Good ML, flexible rules |
| Signifyd | Want chargeback guarantee | $1.5K-4K | Guarantee option, good for high-fraud |
| Forter | High-volume | $2K-5K | Excellent accuracy, enterprise-grade |
| Riskified | Apparel, high-ticket | $2K-5K | Approval focus, good for conversion |
Choose based on: Your industry and whether you want chargeback guarantee option.
What Still NOT to Buy
❌ Manual review team - Handle in-house still (unless >1M/month) ❌ Multiple fraud tools - One is enough ❌ Revenue analytics platforms - Processor reports + Stripe Sigma sufficient
Over $1M/Month: Full Stack
What to Use
| Tool Category | Recommendation | Cost |
|---|---|---|
| Processor | Stripe or Adyen (negotiated) | 2.4-2.7% + $0.30 |
| Fraud detection | Sift, Signifyd, or Forter | $3K-8K |
| Dispute alerts | Verifi + Ethoca | $600-1,500 |
| Chargeback guarantee | Signifyd or Forter (optional) | 0.5-1.5% of covered volume |
| Manual review | In-house team or outsourced | $5K-15K |
| Analytics | Stripe Sigma + BI tool | $200-1K |
| Reconciliation | Accounting integration | $0-500 |
Total monthly tool cost: $8,000-$26,000 (0.8-2.6% of volume)
When to Add Each
Manual review team (at $1M-$2M):
- Full-time fraud analyst
- Cost: $60K-80K/year salary
- Reviews flagged orders, tunes rules, manages tools
Chargeback guarantee (at $2M+ or 0.8%+ CB ratio):
- Cost: 0.5-1.5% of covered volume
- Signifyd or Forter cover approved fraud orders
- Worth it if CB ratio pushing 0.8% (close to VAMP)
Analytics platform (at $3M+):
- Looker, Tableau, or custom BI
- Cost: $500-2K/month
- Deep analysis beyond processor reports
Multi-Processor Strategy
At $5M+/month, consider:
- Primary: Stripe for 80% of volume
- Secondary: Braintree or PayPal for PayPal checkout
- Backup: Traditional processor for redundancy
Cost: Additional reconciliation, integration, labor
Benefit: Negotiation leverage, uptime insurance
Tool ROI Calculator
When Does a Tool Pay for Itself?
Formula: Tool saves money if:
(Chargebacks prevented × CB true cost) > Tool monthly cost
Example - Dispute alerts at $250K/month:
Without alerts:
- 30 chargebacks/month
- Cost: 30 × $85 = $2,550
With alerts ($400/month):
- 12 prevented (40% deflection)
- 18 chargebacks occur
- CB cost: 18 × $85 = $1,530
- Tool cost: $400
- Total: $1,930 vs $2,550 = Save $620/month
ROI: Positive. Buy the tool.
Example - Fraud tool at $100K/month:
Without fraud tool:
- 15 chargebacks/month (0.6% ratio, half are fraud)
- Cost: 15 × $85 = $1,275
With fraud tool ($1,500/month):
- 5 fraud prevented (30% of fraud)
- 12 chargebacks occur
- CB cost: 12 × $85 = $1,020
- Tool cost: $1,500
- Total: $2,520 vs $1,275 = LOSE $1,245/month
ROI: Negative. Don't buy yet.
Wait until:
- Volume hits $300K+ OR
- CB ratio hits 0.8%+ OR
- Fraud losses exceed $3K/month

- Reconciliation (full automation)
- Reporting (automated dashboards)
Total time: 20-40 hours/week (full-time person or split across team)
Special Scenarios
High-Risk Business (Supplements, High-Ticket, etc.)
Add fraud tool earlier:
- $100K/month if CB ratio >0.8%
- $250K/month regardless of ratio
- Consider chargeback guarantee at $500K+
Why: High CB ratio pushes you into VAMP. Prevention is critical.
Subscription/SaaS
Different tool priorities:
| Volume | Add First | Add Second |
|---|---|---|
| Under $100K | Stripe Billing | Dispute alerts |
| $100K-$500K | Dispute alerts | Dunning optimization |
| >$500K | Fraud tool | Chargeback automation |
Why different: Subscriptions have lower fraud but different dispute patterns (recurring billing disputes).
Card-Present Retail
Minimal tools needed:
| Volume | Tool Stack |
|---|---|
| Under $250K | Square POS + built-ins only |
| $250K-$1M | Square + dispute alerts |
| >$1M | Consider full POS (Clover) + alerts |
Why minimal: Card-present fraud is 10x lower than CNP. Tool ROI is weaker.
Common Tool Mistakes
Mistake 1: Buying Fraud Tool Too Early
Symptom: $100K/month business paying $1,500/month for Sift
Cost: $1,500/month tool, prevents $400/month in chargebacks
Fix: Downgrade to Stripe Radar until $500K/month
Mistake 2: No Dispute Alerts at $500K
Symptom: $500K/month, 40 chargebacks/month, no alerts
Cost: 16 preventable CBs × $90 = $1,440/month lost
Fix: Add Verifi + Ethoca immediately ($400-600)
Mistake 3: Using Multiple Fraud Tools
Symptom: Sift + Signifyd both running
Cost: $4K-6K/month, redundant
Fix: Choose one, cancel the other
Mistake 4: Chargeback Guarantee Too Early
Symptom: $300K/month business paying 1.5% for guarantee
Cost: $4,500/month for guarantee that covers $500/month in chargebacks
Fix: Cancel guarantee, use standard fraud tool
Mistake 5: No Tools at $1M/Month
Symptom: $1M/month, 80 chargebacks, manual fraud review
Cost: 80 × $90 = $7,200 + 40 hours labor = $9,200/month
Fix: Add fraud tool ($3K) + alerts ($600) = Save $5,600/month
Test to Run
Tool stack audit (if already processing):
Week 1: List current tools
- What tools are you paying for?
- Monthly cost for each: $______
- Total tool spend: $______/month
Week 2: Calculate ROI for each 4. For each tool, estimate chargebacks prevented 5. Calculate savings: CBs prevented × true CB cost 6. Compare to tool cost
Week 3: Decision 7. Tools with negative ROI: Cancel 8. Missing tools with positive ROI: Buy 9. Right-size your tool stack for your volume
Success criteria: Every tool you pay for has positive ROI. No missing tools that would have positive ROI.
Scale Callouts
Starting out (under $10K/month):
- Zero paid tools
- Processor built-ins only
- Manual everything
Growing ($50K-$250K):
- Add dispute alerts at $100K or 0.6% CB
- Still manual fraud review
- Budget $300-600/month
Scaled ($500K-$2M):
- Fraud tool required
- Dispute alerts required
- Consider hiring help
- Budget $2K-5K/month
Enterprise ($5M+):
- Full stack
- Dedicated team
- Custom integrations
- Budget $15K-50K/month
Where This Breaks
-
ROI calculation assumes tool works: If fraud tool false positive rate is high, you decline legitimate orders. Factor lost sales into ROI.
-
Contract lock-in: Some tools require annual contracts. Calculate full-year cost, not just monthly.
-
Integration costs not included: Adding a tool requires dev time (10-40 hours). Factor this into payback period.
-
Tool effectiveness varies: 40% chargeback deflection is average. Your actual deflection may be 20-60%. Monitor actual performance.
-
Volume spikes: If you go from $100K to $500K in one month, you'll need tools immediately. Can't wait for ROI analysis.
Next Steps
Choosing your first tool?
- Calculate your current CB ratio and count
- Use decision matrix above
- Start with dispute alerts if at $100K+ or 0.6%+ ratio
Optimizing current stack?
- Run ROI audit for each tool
- Cancel tools with negative ROI
- Add tools you're missing with positive ROI
Growing rapidly?
- Plan tool additions 3 months ahead
- Budget for next tier before you need it
- Don't wait until crisis to add tools
