Is Square Invoices actually free?
Disclosure. We applied to Square’s affiliate programme through Impact. One application was declined and one is still pending. We have earned nothing from Square, there is no affiliate link on this page, and if the pending application is approved a page like this one could pay us. You are entitled to weigh that against what follows — which includes telling you that Square’s $149 plan is worth nothing to an invoicing business, and that the cheapest way to take money through Square is the one it does not put on the invoice.
Yes. $0 a month, no client limit, no invoice limit, and that plan is a real product rather than a trial. The subscription was never the question. What decides your bill is which button your client presses — and the same $5,000 costs anywhere from $0 to $165.30 depending on the answer.
The answer
Yes — the plan is genuinely $0. But the same invoice has four different prices, and Square shows you the expensive one first.
- ✅$0/month, unlimited invoices, unlimited clients. No trial, no expiry. You pay only when a client pays you.
- 🏦Bank transfer costs 1% against 3.3% + 30¢ for a card. On a $5,000 invoice that is $50 instead of $165.30 — and it is available on the free plan.
- 🔑The same card, through a different door, is 0.4% cheaper. Square charges free-plan users 3.3% + 30¢ on an invoice link but 2.9% + 30¢ on “Online API”.
- ❌Do not buy Premium for the rates. At $149/mo its online rate is identical to the $49 plan. That is $1,200 a year for phone support.

The same invoice, four prices
Square publishes its plan prices on one page and its processing rates on another, which is how a $0 plan ends up being the most expensive way to get paid. Here they are together, for the free plan, on one identical $5,000 invoice.
| How your client pays | Rate (free plan) | On a $5,000 invoice |
|---|---|---|
| Cash or cheque | Free | $0.00 |
| Bank transfer (ACH) | 1%, $1 minimum | $50.00 |
| Card, via “Online API” | 2.9% + 30¢ | $145.30 |
| Card, via the invoice link | 3.3% + 30¢ | $165.30 |
| Keyed in / card on file | 3.5% + 15¢ | $175.15 |
| Afterpay | 6% + 30¢ | $300.30 |
Same work, same client, same $5,000 — and a spread of $300.30 between the cheapest paid route and the most expensive one. No plan upgrade changes that spread by anything like as much as the choice of route does.
The cheaper door Square does not put on the invoice
This is the finding worth the whole page. Square’s fee table lists “Online” and “Online API” as separate lines. On the paid plans they are the same — 2.9% + 30¢ either way. On the free plan they are not:
Free plan, same card, same money:
Invoice payment link — 3.3% + 30¢
“Online API” — 2.9% + 30¢
On a $5,000 invoice that is $165.30 against $145.30. You lose $20 for using the button Square puts in front of you. On $1,000, $4. On $100, 40¢.
We are not going to overstate what this means in practice. “Online API” is a developer route — a payment link generated through Square’s API, or a checkout embedded in your own site — and for most people invoicing a client it is not a switch you can flip. But it establishes something worth knowing: the free plan’s 3.3% is not what it costs Square to move your money. It is a price attached to the convenient door.
What we did not verify. We read this from Square’s published fee table and did not build an integration to confirm the rate in practice, nor could we establish exactly which flows Square counts as “Online API” versus “Online”. If the 0.4% matters at your volume, ask Square directly which category your setup falls into before you build anything — that is a question their support can answer in a sentence and we cannot.
Is the $49 plan worth it?
Square Plus costs $49 a month per location — $588 a year. It drops the online card rate from 3.3% to 2.9%, adds custom invoice templates and payment schedules, and caps ACH fees at $10.
Take the rate cut first, because it is the reason people upgrade and it is almost never the right one.
Break-even on the card rate alone. The saving is 0.4% of your online card volume. To recover $588 a year you need
$588 ÷ 0.004 = $147,000 of online card payments a year.
Below that, the subscription costs more than it saves. Most one-person businesses are not close.
Now the ACH cap, which is the real reason and behaves completely differently. On the free plan a bank transfer costs 1% with no ceiling. On Plus it is capped at $10 per invoice.
| Invoice paid by bank | Free plan | Plus (capped) | Saved |
|---|---|---|---|
| $1,000 | $10.00 | $10.00 | $0.00 |
| $2,000 | $20.00 | $10.00 | $10.00 |
| $5,000 | $50.00 | $10.00 | $40.00 |
| $10,000 | $100.00 | $10.00 | $90.00 |
The cap only starts working above $1,000, because below that 1% is already under $10. And here is the part that catches people: one $5,000 bank-paid invoice a month saves $40 — which is less than the $49 you just spent.
When Plus actually pays for itself:
1 × $5,000 by bank per month → saves $40 — stay on Free
4 × $2,000 by bank per month → saves $40 — stay on Free
2 × $5,000 by bank per month → saves $80 — Plus wins
1 × $10,000 by bank per month → saves $90 — Plus wins
The one plan nobody invoicing should buy
Square Premium is $149 a month per location. Against Plus at $49 it improves the in-person rate from 2.5% to 2.4% and adds 24/7 phone support.
Its online rate is 2.9% + 30¢. So is Plus’s.
For a business that gets paid through invoices, Premium buys a 0.0% rate improvement for $1,200 a year. ($149 − $49) × 12 = $1,200. The 0.1% in-person cut only reaches you if you take cards in person, and at 0.1% you would need $1,200,000 of in-person volume a year for it to pay for itself.
If you want 24/7 phone support and can justify $1,200 a year for it, that is a legitimate purchase and we are not going to argue with it. Just buy it knowing that is what you are buying, because the plan is presented as “lowest processing fees” and for online invoicing that claim is not true relative to the plan below it.
Which one are you?
Which one are you?
🏦 My clients could pay by bank transfer if I asked
Ask, and stay on the free plan. 1% against 3.3% + 30¢ is $115.30 back on every $5,000 invoice. This single change is worth more than any plan on this page, and it costs nothing.
🧾 I bill small amounts — under $100 a time
The 30¢ is your real problem, not the 3.3%. A $50 invoice paid by card costs 3.90%. Bank transfer at $50 costs 2% because of the $1 minimum — still better, but the honest fix is fewer, larger invoices. No plan on this page helps you.
💰 I invoice two or more large amounts a month by bank
Plus at $49 pays for itself on the $10 ACH cap alone — two $5,000 transfers save $80 a month. Buy it for the cap, not for the card rate; the card rate needs $147,000 a year to break even.
📞 I was about to buy Premium at $149
Don’t, unless you want the phone support. Its online rate is identical to the $49 plan. $1,200 a year, 0.0% better online.
📋 I want bookkeeping in the same place as invoicing
Square Invoices is a payment product with reporting, not a bookkeeping product. If accounts matter more than the payment rate, compare Wave, which is free and includes real bookkeeping, and Zoho Invoice. Head-to-head: Square Invoices vs Wave. Different jobs, both free.
What we could not verify
“Per location”. Both paid plans are priced per location. For a one-person business that is one location, so $49 and $149 are the figures used here — but if you run two, the plan cost doubles and none of the break-even numbers above hold.
Which flows count as “Online API”. The 2.9% free-plan rate is published; the boundary between it and the 3.3% invoice-link rate is not something we could establish from the fee page. Ask Square before relying on it.
Country. All figures are the United States ones, read from Square’s US pages. Square publishes different rates by country and the ACH route does not exist in most of them. Read your own country’s fee page before using any number here.
Questions people actually ask
Is there a catch to the $0 plan?
Not in the way there usually is. There is no client cap, no invoice cap, no trial clock, and no branding on your invoice that you have to pay to remove. The catch is that the free plan carries the highest online card rate of the three — 3.3% against 2.9% — so Square is funded by your payment volume rather than your subscription. Which is a fair trade if your invoices are small, and an expensive one if they are large and paid by card.
Can I just tell clients to pay by bank transfer?
Yes, and on the free plan it is the single most valuable thing on this page. Square supports ACH on the invoice itself at 1%. The friction is that a bank transfer takes a few days and some clients simply prefer the card. That trade — days of waiting against 2.3 percentage points — is worth doing the arithmetic on rather than defaulting.
Does Square hold my money?
Next-day transfers are listed as included on every plan. We have not tested this and payment processors do sometimes hold funds on new or unusual accounts, which is a risk with every processor rather than a Square-specific one. If cash flow timing is critical to you, ask about it before you migrate rather than after.
How does this compare with Square Appointments?
They are separate products with separate free plans, and the appointment product has its own rate structure. We costed it separately in Is Square Appointments actually free?.
The thing that actually decides it
Not the plan. The plan is free, genuinely, and for most one-person businesses it should stay free.
What decides your bill is a question you have probably never asked a client: how would you like to pay? On a $5,000 invoice the answer is worth $165.30 if it is a card, $50 if it is a bank transfer, and nothing at all if it is a cheque. Square will happily process all three and only advertises the price of one.
Send your next invoice with bank transfer set as the default and the card link still available. You will find out inside a month what your clients actually prefer, and the answer will be worth more than any upgrade on this page.
