How to add Square to your website
Square is a payments platform combining card readers with online checkout links, used by businesses already taking card payments in person with a Square reader. Here's how to put it on your own website, which embed option to pick, and what goes wrong.
Quick answer
Get the code from your Square Dashboard under Online, in the Payment Links or Checkout Links area. For most people the right choice is the payment link — a hosted checkout page for a fixed item and price. Paste it into a code or embed block on your site — not a plain text field — then place it beside your main call to action and test the whole flow on a phone before relying on it.
Square: which option to use
| Option | What it does |
|---|---|
| Payment link | A hosted checkout page for a fixed item and price. |
| Buy button embed | Square generates embeddable button code for your site. |
| Donation or custom amount link | Lets the customer choose the amount — useful for deposits and tips. |
Step-by-step
- 1
Find the code or link in your account
Square keeps this in your Square Dashboard under Online, in the Payment Links or Checkout Links area. Copy what you need before touching your website — most of the time people lose is spent hunting for the snippet, not installing it.
- 2
Pick the right option for the job
The table above is the decision. Payment link: A hosted checkout page for a fixed item and price. Buy button embed: Square generates embeddable button code for your site. Choosing before you paste saves rebuilding the section later.

Paste it into a code or embed block
This needs an HTML, code or embed block — not a plain text field, where the code will simply appear as text on your page. On Adviita, ask the AI editor to add an embed section and drop the code in. On WordPress use a Custom HTML block, on Squarespace a Code block (Business plan or above), and on Wix an Embed HTML element.

Put it where the decision happens
Getting paid should take the customer as few taps as possible — every extra step is money left on the table. A widget three scrolls down does a fraction of the work of the same widget beside your main call to action. Decide what the page is for, then place it at the point the visitor is deciding.

Check it on an actual phone
Most visitors to a small business website arrive on a phone, and embeds are where mobile layouts break. Open your live site on your own phone and confirm it loads, fits the screen without sideways scrolling, and does not push your contact button out of view. Third-party embeds are also the most common cause of a slow page, so if it noticeably delays loading, consider a plain link instead.

Test it end to end before you rely on it
Run through the whole flow yourself as a customer would — make a small real payment — and confirm what should happen actually happens. Broken embeds fail silently, and the first person to notice is usually a customer who has already given up.
Tips & best practices
- ▸Square's online rate differs from its in-person rate. If most of your volume is online, compare it against Stripe before committing.
- ▸Payment links can have inventory attached; if you sell a limited-stock item, set the quantity or you will oversell.
- ▸Square accounts are region-specific and features differ by country — check the payment link feature exists in yours before planning around it.
- ▸Re-test the embed after any change to your site, your plan, or the connected account — third-party widgets break quietly and nothing tells you.
Common questions
How do I create a Square payment link?
+−
In your Square Dashboard, open the Online section and find payment or checkout links. Create a link for the item, service or amount you want to charge, then copy the URL. Put it behind a 'Pay now' or 'Book and pay' button on your website, or send it directly to customers.
Can I take payments on my website without a full online store?
+−
Yes, and for most service businesses it is the better approach. A payment link or two — a deposit, a consultation fee, a fixed-price service — takes minutes to set up and avoids running a whole store platform you do not need.
Do I need a developer to add Square to my site?
+−
No. Every option here is copy and paste into a code or embed block, which every mainstream website builder provides. The only genuine blocker is a builder or plan that does not allow custom code at all — Squarespace, for instance, requires a Business plan or above for code blocks.
Will adding Square slow down my website?
+−
Any third-party embed has some cost, because it loads code from another company's servers. One is usually unnoticeable; four or five on the same page is where small business sites become visibly slow. If page speed matters to you, prefer a plain link over a script wherever the option exists, and keep embeds to the pages that genuinely need them.
