The “Smart Anchor” strategy optimizes tip collection through evidence-based behavioral nudges while maintaining a customer experience that feels reasonable and non-aggressive.
Core principle: Use dollar amounts for small orders (where they outperform percentages) and calibrated percentage anchors for larger orders (where the compromise effect and high-anchor framing shift selection upward).
Navigation: Square Dashboard > Devices > Point of Sale > Checkout > Tips (Menu structure may vary slightly by Square version.)
| Setting | Value |
|---|---|
| Tip Mode | Smart Tips |
| Dollar Amount Threshold | $10 (Square default) |
| Dollar Options | $1 / $2 / $3 (Square Smart Tips default for under $10) |
| Percentage Options | 18% / 20% / 25% (custom - set via percentage mode first, then re-enable Smart Tips) |
| Custom Tip Amount | Enabled |
| No Tip | Visible (default Square placement) |
Setup note: Square’s Smart Tips uses fixed $1/$2/$3 for under-$10 transactions (not customizable). To set custom percentages for over-$10 transactions: first select “Set Percentage Amounts,” enter 18/20/25, save, then go back and enable Smart Tips. This preserves your custom percentages while using the Smart Tips dollar-amount behavior for small orders.
Dollar amounts outperform percentages for transactions under $10-$15. On a $7 order:
| Format | Low | Mid | High |
|---|---|---|---|
| Percentages (15/20/25%) | $1.05 | $1.40 | $1.75 |
| Dollar amounts ($1/$2/$3) | $1.00 | $2.00 | $3.00 |
The dollar format produces a higher middle anchor ($2.00 vs $1.40). With ~45% of tippers selecting the middle option (the “compromise effect”), this raises the average tip per tipper by ~$0.40.
Raising the threshold from the old system’s $8 to $10 captures an additional ~15-20% of tickets in the higher-performing dollar format.

The old percentage tier (12/15/18%) was below current national norms. The new configuration uses two proven principles:
Floor anchoring: Few customers tip below the lowest displayed option. Moving the floor from 12% to 18% raises the minimum tip for ~25% of tippers who default to the lowest button. On a $12 order: $2.16 vs $1.44 (+$0.72 per tipper).
Compromise effect and high-anchor framing: The 25% option exists primarily to make 20% feel like the moderate, reasonable choice. When presented with ascending options, consumers disproportionately select the middle option to avoid appearing either cheap or extravagant (Simonson, 1989). The high anchor also shifts the perceived norm upward (Tversky & Kahneman, 1974), increasing middle-option selection by 3-4 percentage points based on industry data from Toast (2022-2023).
Why not 20/25/30%: 30% risks triggering tip fatigue backlash. 77% of consumers already say tipping culture is “ridiculous” (Popmenu, 2025). 25% stays within the range customers consider acceptable.

Custom tips on small orders average $0.50-$1.00 (below presets). ~5-10% of customers use it. Removing it pushes 3-5% of would-be tippers to “No Tip” entirely.
Net revenue impact: Approximately zero. But it signals respect for customer autonomy, which protects reputation and online reviews.

Hiding or adding friction to “No Tip” increases tips 5-15% short-term but 60% of consumers say aggressive tip screens negatively affect their perception of the business (Bankrate, 2023). The social pressure of the screen itself is sufficient - simply having tip suggestions increases tipping by 23.8% vs no prompt.

| Option | Selection Rate | Tip Amount | Weighted Contribution |
|---|---|---|---|
| $1 | 22% of tippers | $1.00 | $0.22 |
| $2 | 45% of tippers | $2.00 | $0.90 |
| $3 | 20% of tippers | $3.00 | $0.60 |
| Custom | 8% of tippers | ~$0.75 | $0.06 |
| Round-up/other | 5% of tippers | ~$0.50 | $0.03 |
| No Tip | 35% of all tickets | $0.00 | - |
| Avg tip/tipper | $1.81 | ||
| Avg tip/ticket (incl. non-tippers, 65% participation) | ~$1.18 |
Math: 55 tickets x 65% = 35.75 tippers. 35.75 x $1.81 = $64.71. $64.71 / 55 = $1.18/ticket.
| Option | Selection Rate | Tip Amount | Weighted Contribution |
|---|---|---|---|
| 18% | 25% of tippers | $2.52 | $0.63 |
| 20% | 45% of tippers | $2.80 | $1.26 |
| 25% | 20% of tippers | $3.50 | $0.70 |
| Custom | 7% of tippers | ~$1.50 | $0.11 |
| Round-up/other | 3% of tippers | ~$1.00 | $0.03 |
| No Tip | 30% of all tickets | $0.00 | - |
| Avg tip/tipper | $2.73 | ||
| Avg tip/ticket (incl. non-tippers, 70% participation) | ~$1.91 |
Math: 18 tickets x 70% = 12.6 tippers. 12.6 x $2.73 = $34.40. $34.40 / 18 = $1.91/ticket.
| Metric | Current | Projected | Change |
|---|---|---|---|
| Daily tips from under-$10 (55 tickets) | - | ~$64.71 | - |
| Daily tips from over-$10 (18 tickets) | - | ~$34.40 | - |
| Total daily tips (73 tickets) | $75.00 | ~$99.11 | +$24.11 |
| Avg tip/ticket | $1.03 | ~$1.36 | +$0.33 (+32%) |
| Weekly tips | ~$525 | ~$694 | +$169 |
| Annual tips (350 operating days) | ~$26,250 | ~$34,689 | +$8,439/year |
Note: Projections based on Saturday volume (73 tickets). Actual results will vary by day - weekdays likely have lower volume. Annual estimate assumes similar averages across operating days; adjust for actual weekly patterns. These are estimates based on industry averages and published research; actual results will depend on your specific customer base.
Track these metrics weekly for the first month after switching to Square:
| Signal | Action |
|---|---|
| Participation drops below 55% | Lower percentage tier to 15/18/22% |
| $1 selected by >35% of tippers | Test raising to $1/$2/$4 |
| Average tip exceeds $1.40 after 4 weeks | Current config is working, hold steady |
| Average tip exceeds $1.60 after 4 weeks with no complaints | Consider testing $2/$3/$4 dollar tier |
| 3+ independent complaints about tipping within 2 weeks | Reduce percentage ceiling to 22% |
If possible, configure Square with the old system’s settings ($1/$2/$3 under $8; 12%/15%/18% over $8) for the first 1-2 weeks before switching to the Smart Anchor configuration. This establishes a same-system baseline and isolates the impact of the configuration change from the POS migration itself.
