Square for a One-Person Shop — Unboxing to First Sale
Last verified: August 2026
What Square really costs, which reader to buy (maybe none — your phone already takes tap payments), what they ask for at signup, when the money lands in your bank, and how refunds, disputes, and the 1099-K work. Written by a one-person shop that runs on Square every working day.
"Just get Square" is good advice that skips forty questions
If you run a one-person business — a repair shop, a market booth, a cleaning route, a bakery table — somebody has already told you to "just get Square." It's usually right. But that advice skips everything that happens next: what a $100 card sale actually puts in your bank account, whether you need to buy hardware at all, why they ask for your Social Security number, and what to do the first time a customer's bank yanks a payment back.
I can answer those from experience instead of a brochure: I run my own business on Square. The handheld reader rides in my truck, phone orders get keyed in, and the money shows up the next business day. This guide is everything I'd tell you across the kitchen table, in order, from signup to first sale — including the honest chapter on when Square is NOT the right fit.
What Square costs on the free plan (checked mid-2026)
- In person — tap, dip, or swipe: 2.6% + 15¢. On a $100 sale you keep $97.25.
- Online or invoice paid by card: 3.3% + 30¢ (Square raised this from 2.9% in January 2026).
- Keyed in by hand / card on file: 3.5% + 15¢ — the expensive one; use it for phone orders, not for customers standing in front of you.
- Invoice paid by ACH bank transfer: 1% ($1 minimum) — the quiet bargain for big invoices.
- Monthly fee: $0 on the free plan. Paid tiers ($49 and $149/month) exist, but most solo shops never need them.
- Rates change occasionally — always confirm at squareup.com before you count on an exact number.
You might not need to buy anything
A reasonably recent iPhone or Android phone can take contactless cards by itself through the free Square app — Square calls it Tap to Pay. The customer taps their card, phone, or watch on the back of your phone, at the same in-person rate as a real reader. Add invoices, payment links, and the virtual terminal (all built in), and many service businesses can run their first month on zero hardware. If you do buy one thing, make it the $59 Square Reader (2nd generation) — the palm-size tap-and-chip reader that's the one-person-shop workhorse. Square Stand ($149), Terminal ($299), and Register (around $800) exist for counters that need them.
What signup actually asks for
- Your legal name, date of birth, and home address — standard identity checks required by federal banking rules.
- Your Social Security number (or ITIN). This surprises people, but every legitimate processor must ask. Sole proprietors don't need an EIN or any business paperwork to start.
- Your bank account (routing and account numbers) — verified before your first transfer can arrive.
- Sometimes a photo of your driver's license. Normal, not a red flag.
- Have an EIN? Add it in tax settings so your 1099-K reports to the business instead of your personal SSN.
When the money lands
Square batches each day's sales and sends them to your bank automatically — the standard schedule is next business day, free. Instant transfers exist for a fee (1.95% as of mid-2026), which is a lot to pay for impatience: moving $500 a day early costs about $9.75. Let the free schedule do its thing, and check the Dashboard's Transfers page any time a deposit seems missing — it answers the question in ten seconds.
Refunds, disputes, and the 1099-K — the three scary things, defanged
- Refunds: thirty seconds in the app, up to one year after the sale. One catch — Square keeps the original processing fee (industry standard since 2023).
- Disputes (chargebacks): rare for honest shops. Respond in the Dashboard with your receipt and records by the deadline. Square charges no extra dispute fee — many processors bill $15–$25 per dispute.
- The 1099-K: the federal threshold reverted to more than $20,000 AND more than 200 transactions under the 2025 tax law (the $600 rule was repealed). Some states set lower thresholds. Either way, all income is taxable — the form just reports what Square processed, gross, before fees and refunds.
When Square is NOT the right fit
Honest list, because you deserve the whole picture: if you process serious volume (Square offers custom pricing over $250,000/year — and that's also where interchange-plus processors start beating flat-rate pricing by real money), if your business is in a category Square's terms prohibit, or if your pattern is one or two enormous transactions a month that trip automated fraud holds. None of those describe the typical one-person shop — which is why I keep recommending Square and keep using it myself.

Why I wrote this
Most guides about Square are written by websites that earn a commission. This one is written by a guy whose own business runs on it — the handheld reader in my truck has taken years of real payments in Portage County driveways and kitchens. I don't work for Square and they don't pay me; I just know the setup cold because I live in it, and a one-person shop deserves advice from another one-person shop. — Bill
