1. Liability cap (highest): A one-month fee cap is likely far below losses from service failure, data breach, or IP claims. Replace: “Provider’s aggregate liability shall not exceed the greater of fees paid in the 12 months preceding the claim or $[X], and the cap shall not apply to Provider’s gross negligence, willful misconduct, data breach, or IP infringement.”

1. Broad customer indemnity: Customer must indemnify Provider even for claims caused by Provider’s negligence, shifting Provider’s own fault to Customer. Replace: “Customer shall indemnify Provider only for third-party claims arising from Customer Data to the extent caused by Customer’s breach or negligence, excluding claims caused by Provider’s negligence, willful misconduct, or breach.”

1. Unilateral modification: Provider can change the Services or terms anytime by website notice, with continued use as acceptance, so Customer can be bound to unknown material changes. Replace: “Provider may modify the Services or terms only with 30 days’ prior written notice; material adverse changes require Customer’s written consent, and Customer may terminate without penalty before they take effect.”

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.”

Calculated metrics

Notes: Q3 2026 adjusted operating income excludes the $0.21M one-time lease termination charge: $4.82M − $1.98M − ($2.31M − $0.21M) = $0.74M. Revenue per store = quarterly revenue ÷ quarter-end stores.

Board summary bullets

• Revenue grew 17.6% YoY to $4.82M, with store count up to 38 from 33; revenue per quarter-end store rose 2.1% to $126.8K.
• Gross margin compressed 3.0 pp to 58.9% from 62.0%, as COGS grew 26.9% versus revenue growth of 17.6%.
• Reported operating margin was 11.0%, down 1.7 pp from 12.7%; the $0.21M lease termination charge reduced Q3 2026 operating margin by about 4.4 pp.
• Excluding the one-time charge, Q3 2026 operating margin was 15.4% on $0.74M adjusted operating income, up 2.7 pp versus Q3 2025 reported operating margin, indicating stronger underlying profitability despite gross-margin pressure.

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.

Subject: Let’s find a workable path on the 18% increase

Hi Jordan,

I appreciate the partnership we’ve built with BrightSmile across our 12 locations, and I want to keep it strong. I also need to be direct: we can’t absorb the full 18% increase starting next month.

Two alternatives I’d like to discuss:

1. Phase in the increase over six months, with 6% now and the remainder reviewed in Q3.
2. Hold current pricing on our top three product categories in exchange for a 12-month volume commitment.

Can we schedule a call this week? I’m available Tuesday or Thursday afternoon. I’m confident we can find a solution that works for both sides.

Warmly,

Maya Chen

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

The bug is that the function divides by len(orders), which includes refunded orders, instead of dividing by the number of non-refunded orders. It also needs to handle the case where there are no non-refunded orders.

def average_order_value(orders):
    """Return the average order total, ignoring refunded orders."""
    total = 0
    count = 0
    for order in orders:
        if order["status"] != "refunded":
            total += order["total"]
            count += 1
    return total / count if count else 0

Test cases:

orders1 = [
    {"status": "paid", "total": 100},
    {"status": "refunded", "total": 999},
    {"status": "paid", "total": 50},
]
assert average_order_value(orders1) == 75

orders2 = [
    {"status": "refunded", "total": 100},
    {"status": "paid", "total": 20},
]
assert average_order_value(orders2) == 20

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

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

This uses SUMIFS to sum revenue in C2:C5000 only where:

• B2:B5000 equals "West", and
• A2:A5000 is on or after July 1, 2026, and
• A2:A5000 is on or before September 30, 2026.

It assumes column A contains real Excel dates, not text.

=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.
