Square Invoices: invoicing software platform

The short answer

Buy Square Invoices if you can persuade clients to pay by bank transfer, because ACH via invoice is 1% with a $1 minimum and the paid tiers cap that fee at $10. On a five-figure invoice that cap is worth more than the $49 plan costs. It is also the obvious answer if you already take card payments in person through Square, since invoicing sits inside the same plan rather than being a second subscription.

Skip it if you invoice internationally: Square states plainly that it does not support multi-currency acceptance today, and a card issued outside the United States adds a further 1.5%. Skip it too if your clients pay by card and will not move, because 2.9% + 30 cents on every paid invoice is a revenue share rather than a software fee, and a flat-rate competitor will beat it. And skip it if you are buying invoicing alone, because the plan fee is charged per location on a rate card built around point of sale.

Where Square Invoices fits

Square Invoices pricing

Square publishes both a software rate card and a processing rate card, and for an invoicing buyer the second one is the bill. Read on 16 October 2026, the three plans are Free at $0/mo. per location, Plus at $49/mo. per location and Premium at $149/mo. per location. An invoice paid by card is 3.3% + 30 cents on Free, falling to 2.9% + 30 cents on Plus and Premium. An ACH bank transfer via invoice is 1% with a $1 minimum on every plan, and only the paid tiers carry the $10 fee cap.

What Square publishes

Square Free

Invoice card payments at 3.3% + 30 cents, ACH via invoice at 1% with a $1 minimum and no fee cap.

Invoice card payments at 2.9% + 30 cents, in-person at 2.5% + 15 cents, and ACH via invoice at 1% with a $1 minimum and a $10 fee cap. A free trial is offered but its length did not render in the pull.

In-person card payments at 2.4% + 15 cents, invoice card payments still at 2.9% + 30 cents, a 0% gift card load fee against 2.5% on the lower tiers, and bitcoin conversions at 0.5% against 1.0%.

Custom pricing above $250,000 processed per year

Quote-based (By arrangement with the Square team)Custom pricing and processing fees, hardware discounts, onboarding and implementation support, technical specialists and account management. No figure is published.

Two things to know about these figures. First, Square's rate card covers the whole platform, not invoicing alone, so the device and kiosk add-ons below belong to the point-of-sale side of the same plans. Second, the plan prices are confirmed twice on the same page, in the additional fees table and in the page's own structured data, which is more corroboration than most vendors in this category offer.

The subscription is the small number. Four things move the real one.

1. How your clients pay. An invoice settled by card costs 3.3% + 30 cents on Free or 2.9% + 30 cents on a paid tier. The same invoice settled by bank transfer costs 1% with a $1 minimum. Steering clients to ACH is the single largest lever on this bill, and it is a lever you control through how you present the invoice rather than through which plan you buy.
2. Your invoice sizes, because of the cap. ACH via invoice is 1% with a $1 minimum on every plan, but only Plus and Premium add the $10 fee cap. On invoices of a few thousand dollars and up, that cap changes the economics completely: the uncapped 1% on Free scales with the invoice while the capped version does not. Model it against your three largest invoices from last quarter.
3. How many locations Square counts. Plus is $49/mo. per location and Premium is $149/mo. per location, and Square says the fee applies to each location you run. This is the figure most often got wrong in a budget, because the plan card reads like a single monthly fee and the fee table does not.
4. Whether you cross the custom-pricing line. Square invites businesses processing over $250,000 per year to discuss custom pricing and processing fees. If you are anywhere near that annual volume, have that conversation before you commit to a published tier, because both the plan and the rate are on the table at that point and neither is published.

What costs extra

• Additional locations on the paid tiers: the $49/mo. or $149/mo. fee applies per location.
• Cards presented from outside the United States: an additional 1.5% on top of the applicable rate.
• Manual entry or a card on file: 3.5% + 15 cents on every plan, which is the rate a keyed-in invoice payment attracts.
• Afterpay installments: 6% + 30 cents.
• Payroll: full-service payroll starting at $35 per month plus $6 per person paid.
• Hardware: options starting at $59. Square KDS is $30/mo. per device, or $20/mo. per device on the higher tier. Square Kiosk is $99/mo. per device, with Kiosk Lite on iOS at $50/mo. or $30/mo. depending on plan.
• Gift card load fees: 2.5% on Free and Plus, 0% on Premium. Bitcoin conversions are 1.0% on Free and Plus and 0.5% on Premium, with in-person bitcoin payments at 0% until 2027.

Implementation and commercial terms

Square is more forthcoming on commercial terms than most of this category. These rows are what the page confirms, read on 16 October 2026.

Published price

Yes, for all three plans, plus a full processing rate table

Billing basis

Monthly, charged per location on the paid tiers

Implementation fee

None published. Onboarding and implementation support is offered above $250,000 processed per year with no price attached

Contract

The page states there are no hidden fees and no locked-in contracts, and that you can cancel or switch anytime

Free tier

Square Free at $0/mo. per location, with Square saying you only pay when you take a payment

Paid-tier trial

A free trial is offered but its length renders as an unfilled template placeholder, so no number of days is recorded

Multi-currency

Not supported. Square states it does not support multi-currency acceptance today

Budget this as a percentage, not a subscription. Take last quarter's invoices, split them by how they were paid, and apply 2.9% + 30 cents to the card ones and 1% with a $10 cap to the bank ones. For most service businesses that figure is several multiples of the $49 plan fee, which means the honest question is not whether to pay for Plus but how much of your collections you can move to ACH. If the answer is most of them, the $10 cap alone justifies the paid tier. If the answer is none of them, a flat-rate invoicing tool deserves a look before you commit.

What Square Invoices gives up

How Square Invoices compares

In invoicing the software is often free and the payment rail is the product, so the comparison that matters is what a paid invoice costs. Three of the four below publish a rate; one could not be read at all. Every figure comes from that vendor's own pricing page, checked on 16 October 2026.

What to test in a Square Invoices trial

The Free plan at $0/mo. per location is the way in, and it is open-ended rather than time limited, so you can test with real invoices and real clients before paying anything. A free trial is offered on the paid tier but its length did not render in the pull, so do not plan around one. Five things are worth proving.

1. Send one real invoice to a client who will pay by bank transfer and one to a client who will pay by card, then read the fee on each. That single pair tells you the whole economic story: 1% with a $1 minimum against 3.3% + 30 cents on Free. Everything else in this evaluation is detail on top of that comparison.
2. Ask Square how many locations your business counts as, in writing, before you upgrade. Plus is $49/mo. per location and Premium is $149/mo. per location. If the answer is more than one, the paid tier costs a multiple of what the plan card implies, and that changes whether the lower card rate is worth buying at all.
3. Test milestone payments and recurring invoices on a job that actually has phases. Square lets you schedule multiple payments on a single invoice against specific milestones, and set recurring invoices on a daily, weekly, monthly or yearly schedule. For a contractor or an agency on retainer this is the feature that either removes a spreadsheet or does not.
4. Run a contract through the e-signature flow with a clause you wrote yourself. The invoicing product includes editable, reusable contract templates and custom contract fields for capturing client information. If your engagements need a signed scope before work starts, confirm the signing experience on a phone, since that is where most clients will open it.
5. Price the $10 ACH cap against your three largest invoices from last quarter. The cap exists only on Plus and Premium, and on large bank-paid invoices it is the single clearest reason to leave the free tier. If your invoices are small and numerous instead, the cap is worth nothing to you and Free is the correct plan.
