Square Invoices shows up on every "free invoicing tool" list, and for good reason. It costs nothing to start, the app is clean, and if you already run a Square reader at a booth or a chair, your invoices live in the same place as your card sales.
But there is a difference between a tool that can send an invoice and a tool built for client work. Square is the first. Once invoicing clients is the main way you get paid, three things start to cost you: the card fee, the payment hold risk, and everything Square does not do.
Square Invoices is free until someone pays you
The invoicing software is genuinely free. You do not pay a monthly fee to create and send invoices on the standard plan. What you pay is the processing fee every time a client actually pays.
On the free plan, Square charges 3.3% plus 30 cents per card transaction on an invoice, which Square's own pricing page confirms. ACH bank transfers run 1% with a $1 minimum. There is a paid tier, Square Invoices Plus, that drops the card rate to 2.9% plus 30 cents, so the "free" plan is actually the more expensive one per transaction.
Run the math on a real invoice. A $3,000 project paid by card on the free plan costs you about $99 in fees. Across $40,000 of card-paid client work in a year, that is roughly $1,300 gone to processing. We broke the same fee trap down for PayPal here: Why Freelancers Are Ditching PayPal Invoicing.
Free software, paid transactions. That is the model, and it is fine, as long as you know that is what you signed up for.
The payment hold problem
This is the part that does not show up in the pricing table.
Square, like any processor that moves the money through its own system before paying you out, can hold or freeze a payout. Reports of held balances and sudden account deactivations tend to cluster around larger-than-usual invoices or businesses Square flags as higher risk. For a freelancer, "larger than usual" might just be the biggest project you have ever landed, which is exactly the payment you cannot afford to have stuck.
We wrote about the same structural risk with Wave, whose payment holds are its single most common complaint: Wave is not actually free anymore. The mechanism is the same. When a platform is the merchant of record, it controls the timeline, and you have limited recourse when something trips its risk system.
Nvoyce works differently. The payment link on a Nvoyce invoice runs through your own Stripe account. The money lands in your Stripe balance and pays out on Stripe's standard 2-business-day schedule. Nvoyce is never in the chain holding your funds. There is no intermediary to freeze a payout, because there is no intermediary.
What Square Invoices does not do
Square was built around the point of sale. Its center of gravity is the card reader, the register, and in-person retail. Invoicing was added on top. That history shows up in what is missing for client work:
- No proposals. There is no proposal document a client can formally accept, and no acceptance that turns into an invoice. You handle the "here is the scope and price, do you agree" step somewhere else.
- No follow-up in your voice. Square sends payment reminders, but they are generic. There is nothing that ranks your overdue invoices by money at risk and drafts a follow-up that reads like you wrote it.
- No AI drafting. You build every invoice by hand, line by line.
For a coffee cart or a salon chair, none of that matters. For someone whose income is proposals, projects, and getting paid on time, all of it does.
Where Square still makes sense
Be honest about the fit. If most of your money comes in through in-person card taps and invoices are the occasional exception, Square is the right call. Keeping card sales and invoices in one dashboard has real value, and the free plan is hard to argue with at that volume.
The trouble starts when the ratio flips. Once client invoices are the main event, you are running your business on a tool designed for a register, paying the higher free-plan card rate, and doing the proposal and follow-up work by hand.
The Nvoyce comparison
Nvoyce Solo is $19.99 per month, unlimited documents. You describe the work, and the AI drafts a complete, itemized invoice or proposal in under a minute. A Stripe payment link is attached automatically. When a client accepts a proposal, the invoice generates from it, with scope and price locked. When an invoice goes past due, Payme surfaces it and drafts the reminder in your voice.
The comparison to make is not "free versus $19.99." It is "free plan at 3.3% with no proposals and hold risk" versus "$19.99 flat, payouts direct to your Stripe, proposals and follow-up built in." For anyone billing a few thousand a month in client work, the flat fee is usually the cheaper and calmer option. For the full side by side across tools, see the comparison page.
Nvoyce does not run a point of sale. It does not take in-person card taps or manage a retail register. If that is your main need, keep Square. If your main need is sending professional proposals and invoices and getting paid without chasing, that is the whole job Nvoyce is built for.

FAQ
Is Square Invoices really free?
Creating and sending invoices is free on Square's standard plan, with no monthly fee. You pay a processing fee only when a client pays: 3.3% plus 30 cents per card transaction on the free plan, or 1% for ACH bank transfers. The optional Square Invoices Plus plan lowers the card rate but adds a monthly cost.
How much does Square charge to get paid on an invoice?
On the free plan, 3.3% plus 30 cents for card payments. On a $3,000 invoice paid by card, that is roughly $99. ACH bank transfers are cheaper at 1% with a $1 minimum, if your client is willing to pay that way.
Why does Square hold or freeze payments?
Square moves client payments through its own system before paying you out, so it can hold a payout when its risk system flags a transaction, often on unusually large invoices or higher-risk business types. Tools that use Stripe-native payment links, including Nvoyce, route money through your own Stripe account, so there is no third party holding the funds.
Does Square Invoices have proposals?
No. Square Invoices does not include a proposal document that a client accepts and that converts into an invoice. If your workflow involves sending scope and pricing for approval before billing, you handle that step outside Square. Nvoyce builds the proposal-to-invoice flow into one product.
What is the difference between Square Invoices and Square Point of Sale?
Square Point of Sale handles in-person card payments through a reader or terminal. Square Invoices sends bills clients pay online. They share one account and dashboard. Square's strength is the in-person side, and invoicing was added on top of a point-of-sale product.
Is Square or Nvoyce better for freelancers?
It depends on where your money comes from. If most of it is in-person card sales, Square. If most of it is client projects billed by invoice or proposal, Nvoyce is purpose-built for that, with AI drafting, Stripe-native payouts, and automated follow-up. Nvoyce Solo is $19.99 per month with a 7-day free trial and no credit card required.
If your income is client work, your tool should be built for client work. Try Nvoyce free for 7 days at nvoyce.ai. No credit card required, unlimited documents, payouts straight to your own Stripe.
