ChatGPT vs Gemini

1. Broad, potentially uncapped customer indemnity

The agency could have to defend and pay claims caused by the Provider’s own negligence, while only the Provider benefits from the liability cap.

Replacement: “Customer shall indemnify Provider only against third-party claims to the extent caused by Customer’s unlawful provision of Customer Data, excluding losses attributable to Provider’s negligence, misconduct, or breach. This obligation is capped at twelve months’ subscription fees. Customer controls the defense; settlements imposing obligations on Provider require Provider’s reasonable consent.”

2. Provider liability capped at one month’s fees

This could leave the agency recovering almost nothing after a serious outage, lost client work, or data breach.

Replacement: “Provider’s aggregate liability shall not exceed the fees paid or payable for twelve months of Services. For breaches of confidentiality or data-security obligations, the cap shall be twice that amount. No cap applies to Provider’s fraud, willful misconduct, or liability that cannot lawfully be limited.”

3. Unilateral changes compounded by renewal lock-in

The Provider can change functionality or contractual protections without meaningful consent, while the 90-day deadline risks trapping the agency in another annual term.

Replacement: “Material changes to these terms require Customer’s express written agreement. Provider shall give 60 days’ advance written notice of materially adverse Service changes; Customer may terminate before implementation and receive a prorated refund of prepaid unused fees. Renewal requires Customer’s written agreement; otherwise, this Agreement expires at the end of the current term.”

Here are the three biggest risks for your agency, in order of importance:

1. Unfair Indemnification for Provider’s Negligence

Risk: If the Provider negligently leaks your clients’ sensitive design files, your agency must pay for the Provider’s legal defense and damages. You should never be financially responsible for the Provider’s own carelessness.

Replacement: "Customer shall indemnify Provider against third-party claims arising from Customer Data, except to the extent caused by Provider's breach of this Agreement, negligence, or willful misconduct."

2. Unreasonably Low Liability Cap

Risk: Capping damages at one month of fees leaves your agency practically unprotected if the software fails, loses data, or causes severe business interruption. A standard cap should reflect at least a full year of contract value.

Replacement: "In no event shall either party's aggregate liability exceed the fees paid by Customer in the twelve (12) months preceding the claim."

3. Unilateral Changes Without Direct Notice

Risk: The Provider can strip away critical software features or worsen legal terms simply by updating its website, trapping you in a degraded service. You need direct notice of material changes and a right to exit.

Replacement: "Provider may only modify these terms or materially degrade the Services upon 30 days' prior written notice to Customer via email. If Customer objects, Customer may terminate this Agreement and receive a pro-rata refund of prepaid fees."

Calculated results

¹ Q3 2024 revenue was not provided.

Calculations (financial amounts in millions, except revenue per store):

• Revenue growth: (4.82 ÷ 4.10 - 1) × 100 = 17.6%.
• Gross margin: (Revenue - COGS) ÷ Revenue, giving 58.9% for 2026 and 62.0% for 2025.
• Operating margin: (Revenue - COGS - Operating expenses) ÷ Revenue, giving 11.0% for 2026 and 12.7% for 2025.
• Adjusted Q3 2026 operating margin: [4.82 - 1.98 - (2.31 - 0.21)] ÷ 4.82 × 100 = 15.4%.
• Revenue per store: $4,820,000 ÷ 38 = $126,842.1; $4,100,000 ÷ 33 = $124,242.4.

Board summary

• Revenue increased 17.6% year over year, while the quarter-end store count grew 15.2%, from 33 to 38.
• Gross margin declined 3.0 percentage points to 58.9%, as cost of goods sold grew faster than revenue.
• Reported operating margin fell to 11.0% from 12.7%. Excluding the one-time lease termination charge, Q3 2026 operating margin was 15.4%, or 2.7 percentage points above Q3 2025’s reported margin.
• Revenue per quarter-end store increased 2.1% to $126,842.1. This is a network-level productivity measure, not same-store sales growth, and does not account for store opening dates.

Percentage-point changes are calculated using unrounded margins.

Here are the financial calculations and the summary for the board for Harbor Lane Coffee Co., with all final figures rounded to one decimal place.

Financial Calculations

1. Year-over-Year (YoY) Revenue Growth

• Formula: (($4.82M - $4.10M) / $4.10M) × 100
• YoY Revenue Growth: 17.6%

2. Gross Margin

• Formula: ((Revenue - COGS) / Revenue) × 100
• Q3 2025 Gross Margin: (($4.10M - $1.56M) / $4.10M) = $2.54M / $4.10M = 62.0%
• Q3 2026 Gross Margin: (($4.82M - $1.98M) / $4.82M) = $2.84M / $4.82M = 58.9%

3. Operating Margin (GAAP)

• Formula: ((Gross Profit - Operating Expenses) / Revenue) × 100
• Q3 2025 Operating Margin: (($2.54M - $2.02M) / $4.10M) = $0.52M / $4.10M = 12.7%
• Q3 2026 Operating Margin: (($2.84M - $2.31M) / $4.82M) = $0.53M / $4.82M = 11.0%

4. Adjusted Operating Margin for Q3 2026 (Excluding One-Time Charge)

• Adjusted Operating Expenses: $2.31M - $0.21M = $2.10M
• Adjusted Operating Income: $2.84M - $2.10M = $0.74M
• Q3 2026 Adjusted Operating Margin: ($0.74M / $4.82M) × 100 = 15.4%

5. Revenue per Store

• Formula: Total Revenue / Store Count (in thousands)
• Q3 2025 Revenue per Store: $4,100,000 / 33 stores = $124.2k (or $0.1M)
• Q3 2026 Revenue per Store: $4,820,000 / 38 stores = $126.8k (or $0.1M)

(Note: This represents a 2.1% YoY increase in revenue per store).

Executive Summary for the Board

• Strong Top-Line Expansion: Total revenue grew by 17.6% YoY to $4.8M, driven by the successful net addition of 5 new locations (bringing the total to 38 stores) and a 2.1% increase in average revenue per store (rising from $124.2k to $126.8k).
• Gross Margin Compression: Gross margin declined by 310 basis points YoY from 62.0% to 58.9%, indicating rising product and input costs (COGS) that were not fully offset by menu price increases.
• One-Time Charge Impacted GAAP Profitability: Reported operating margin dipped to 11.0% compared to 12.7% in Q3 2025; however, this drop was primarily driven by a one-time $0.2M lease termination charge.
• Improved Operational Efficiency: Excluding the one-time lease charge, adjusted operating margin expanded to 15.4% (up 270 basis points YoY), demonstrating strong corporate cost control and operating leverage that more than offset the tighter gross margins.

Subject: Finding a workable path on next month’s pricing

Hi Jordan,

We value our relationship with BrightSmile and want to continue working together across our 12 dental locations. However, the announced 18% increase starting next month is beyond what our operating budget can absorb.

Could we explore one of these alternatives?

• Cap the increase at 6% for the next 12 months in exchange for a one-year purchasing commitment.
• Phase in the increase: 6% next month, 6% after six months, and the remaining 6% after 12 months, with no additional increases during that period.

We’re committed to finding a solution that works for both teams, but we can’t accept the full increase next month.

Are you available for a call this week to discuss?

Best,

Maya Chen

Subject: BrightSmile partnership / Upcoming price adjustment

Hi Jordan,

I hope you’re having a great week.

We truly value our partnership with BrightSmile and the reliable service you provide across our 12 clinics. However, I was surprised by the notice of an 18% price increase starting next month. While we understand costs are rising, an increase of that scale isn’t sustainable for our budget, and we cannot accept it.

We want to keep BrightSmile as our primary vendor. To make this work, I’d like to propose two alternatives:

1. Cap the increase at 6% in exchange for signing a two-year volume commitment across all 12 locations.
2. Phase the increase in gradually—starting with 5% next month and revisiting the rest in Q3—while shifting our high-volume consumables to bulk quarterly shipments to cut your fulfillment costs.

Do you have 15 minutes this Thursday to discuss this?

Best regards,

Maya Chen

The function excludes refunded orders from the total but still counts them in the divisor, making the average too low. Divide by the number of non-refunded orders instead, returning 0 when none remain (including an empty input).

def average_order_value(orders):
    """Return the average non-refunded order total, or 0 if none."""
    total = 0
    count = 0
    for order in orders:
        if order["status"] != "refunded":
            total += order["total"]
            count += 1
    return total / count if count else 0

assert average_order_value([
    {"status": "paid", "total": 20},
    {"status": "paid", "total": 40},
    {"status": "refunded", "total": 90},
]) == 30

assert average_order_value([
    {"status": "refunded", "total": 50},
]) == 0

Explanation of the Bug

The function divides the sum by the total number of orders (len(orders)), which includes the refunded orders it was supposed to ignore. Additionally, if the list is empty or contains only refunded orders, it will crash with a ZeroDivisionError.

Corrected Version

def average_order_value(orders):
    """Return the average order total, ignoring refunded orders."""
    valid_totals = [
        order["total"] for order in orders if order["status"] != "refunded"
    ]
    return sum(valid_totals) / len(valid_totals) if valid_totals else 0.0

Test Cases

# Test 1: Standard mix of completed and refunded orders
orders_1 = [
    {"status": "completed", "total": 100},
    {"status": "refunded", "total": 50},
    {"status": "completed", "total": 200},
]
assert average_order_value(orders_1) == 150.0  # (100 + 200) / 2

# Test 2: Edge case where all orders are refunded (prevents ZeroDivisionError)
orders_2 = [{"status": "refunded", "total": 50}]
assert average_order_value(orders_2) == 0.0

=SUMIFS(C2:C5000,B2:B5000,"West",A2:A5000,">="&DATE(2026,7,1),A2:A5000,"<"&DATE(2026,10,1))

SUMIFS totals revenue in column C where the region is West and the order date is on or after July 1, 2026, but before October 1, 2026. The exclusive October 1 cutoff includes all of September 30, even if dates contain times.

Here is the formula you can use:

=SUMIFS(C2:C5000, B2:B5000, "West", A2:A5000, ">=7/1/2026", A2:A5000, "<=9/30/2026")

How it works:

The SUMIFS function adds up numbers in a column, but only for rows that meet multiple specific criteria.

• C2:C5000: This is the sum range (the Revenue column you want to add up).
• B2:B5000, "West": The first condition checks the Region column and only includes rows that say "West".
• A2:A5000, ">=7/1/2026": The second condition checks the Date column for dates on or after (>=) July 1, 2026.
• A2:A5000, "<=9/30/2026": The third condition checks the Date column again to ensure the date is also on or before (<=) September 30, 2026, closing the Q3 window.

(Note: If your local Excel uses DD/MM/YYYY formatting, you can replace the date strings with ">="&DATE(2026,7,1) and "<="&DATE(2026,9,30) to avoid regional formatting errors).
