A Pay button for donations and tips

Why the widget

Variable-amount payments on your page

Hosted Checkout fits a cart with a fixed price. Payment Links fit a billed invoice. The widget fits everywhere the customer chooses how much to pay — donations, tips, contributions, support.

Two lines of HTML

One script tag in your page head, one HTML block where you want the button. No build tools, no library to update.

Customer picks the amount

The widget opens the checkout on top of your page, the donor or supporter types in any amount, the contribution lands on your balance.

Payment without a page change

The checkout opens on top of your page. Your URL stays in the address bar, your brand stays around the modal.

Theme from the dashboard

Accent colour, surface colour, text colour, corner radius — set them in the project's branding panel. The widget picks them up at load.

Where to use

Pages where the customer decides how much

Use the widget where the customer chooses the payment amount: donations, tips, contributions, and pay-what-you-want offers.

Donation pages

Creators, non-profits, charities, religious organisations. Visitor clicks Donate, picks an amount, the contribution lands on your Paymos balance.

Tip jars and support buttons

Streamers, writers, podcasters, open-source devs. Add a Support button to your bio, blog, or about page.

Pay-what-you-want pricing

Indie creators, ebook authors, course makers who let supporters set the price. Customer picks, the payment lands the same way.

Crowdfunding and patron pages

Fundraising campaigns, patron tiers, recurring supporter contributions. Each backer picks their level, you receive it in stablecoin.

How it works

Configure the widget and publish its snippet

Choose the amount mode and brand settings in the dashboard, then place the generated snippet on the page.

  1. 1

    Open the widget builder

    Go to Projects, Widget in your Paymos dashboard. Every option lives in one panel.

  2. 2

    Customise right there

    Pick the amount mode (fixed, customer-pick, suggested), set the default amount, brand colours, corner radius. Live preview updates as you type.

  3. 3

    Paste the snippet on your page

    Add the generated script and HTML block to the page source. The button loads with the current project configuration.

Two lines of code

Add the script tag once, then place the widget block wherever you want the Pay button. The widget creates the invoice on click — no backend setup needed.

Same Paymos backend

The widget creates a real Paymos invoice. The contribution lands on your balance the same way every other Paymos payment does.

Test mode included

Switch to test mode with a single key change. Pay buttons render exactly the same, no real money moves.
