Merchant statement audit checklist — Square

Square simplified merchant statements for the small-business era but that simplicity masks legitimate variation operators should audit. Different fee rates for card-present vs card-not-present vs keyed-in; surcharges on manually entered transactions; Square Capital fee offsets; monthly software subscriptions rolled into the statement. The total picture is not always the headline "2.6% + $0.10" rate.

Section 1 — baseline reconciliation

Gross sales

Square dashboard → Reports → Sales Summary. Gross should match POS transaction count × average ticket.

Refunds and exchanges

Refund line items separate from gross. Exchange-type refunds sometimes report differently.

Discounts and comps

Reduction against gross that happens pre-authorization. Tracked separately from fees.

Processing fees

Total fees line. Calculate effective rate vs gross.

Chargebacks

Separate section. Disputed amounts + fees.

Section 2 — Square fee structures

Card-present (CP) in-person

2.6% + $0.10 default. Some verticals and volumes get interchange-plus.

Keyed-in or manually entered

3.5% + $0.15. Includes card number manually entered at POS (no chip/swipe/tap).

Square Online / invoices (CNP)

2.9% + $0.30 default. Similar to Stripe flat rate.

Square Appointments / Square Online Checkout

Same as Square Online base rate.

Card-on-file recurring (CNP)

3.5% + $0.15 for manually entered recurring. Lower for tokenized recurring on card.

Instant Transfer

1.75% additional on instant payouts (vs next-day free).

Section 3 — effective rate

Calculate:

• Total fees / gross = overall effective rate
• Segment: in-person vs online vs keyed — separate effective rates
• Compare to expected blended rate based on your mix

Mid-market Square merchants often run 2.7-3.3% blended effective. Operators with heavy keyed-in mix push toward 4%.

Section 4 — Square Capital interaction

If you have a Square Capital loan, payments happen via a holdback percentage on sales:

• Holdback percentage on each sale (typically 10-15%)
• Applied to gross before settlement
• Tracked separately in statement
• Remaining balance, payoff trajectory

Some operators don't realize how much Square Capital holdback suppresses cash flow until they audit the statement in detail.

Section 5 — Square subscription fees

• Square Online plans (free tier up through Plus and Premium)
• Square for Restaurants (per-location monthly)
• Square Appointments (tiered per staff)
• Square Team Management
• Square Payroll (per employee)
• Square Marketing (tiered by contacts)

These add up. Operator running Square for Restaurants + Team + Payroll + Marketing often pays $400-$1,500/month in software subscriptions on top of processing fees.

Section 6 — reserve and hold audit

Square reserves are less transparent than Stripe:

• Rolling reserve percentage applied to deposits
• Upfront reserve if applicable
• Hold balance (separate from reserve)
• Minimum balance requirement

Request balance detail from Square support if statement is unclear.

Section 7 — dispute activity

• Chargeback ratio (disputes / transactions)
• Representment submissions and outcomes
• Fees: $25 per dispute (higher than Stripe)
• Square Dispute Resolution submissions

Square's dispute submission UI is less robust than Stripe's. Third-party tools (Chargeflow, Justt) can represent more evidence automatically.

Section 8 — multi-location audit

Square multi-location operators get one consolidated merchant account by default. Per-location audit:

• Enable location reporting in dashboard
• Pull location-level gross, fees, disputes
• Calculate per-location effective rate
• Identify outlier locations (higher fees or more disputes)

Section 9 — Square Risk Manager

Sellers above certain thresholds get automated risk monitoring. Review:

• Flagged transactions (held for review)
• Auto-declined transactions
• Risk Manager rule effectiveness

Section 10 — 1099-K readiness

Square issues 1099-K for gross card volume. Check preview in December:

• Gross matches expected
• Per-state breakdown for multi-state operators
• TIN + business name correct

Anomaly triggers

• Effective rate jump >20 bps quarter-over-quarter (fee structure change or mix shift)
• Sudden hold or freeze on deposits
• Chargeback rate trending up
• Software subscription line items you don't recognize
• Square Capital fee line items when you don't have a loan

When to move off Square

• Effective rate above 3.5% on clean vertical
• Volume above $500k/year with no interchange-plus access
• Software subscription stack > $2,000/month
• Multi-location with reporting limitations
• Restricted-vertical operator at risk of closure

See when to move off Square and multiflow vs Square.

What not to do

• Don't skip quarterly audit. Square fee drift happens quietly.
• Don't ignore keyed-in percentage — it's 90 bps more expensive than chip.
• Don't leave Instant Transfer enabled by default — 1.75% adds up.
• Don't layer Square software products without measuring return.

What to do next

Run the audit. Log results in a simple spreadsheet. Track trends. If anything looks off, open a Square support case with specific line items referenced.
