Link in bio tool for a charity that needs a donate button and a volunteer form

Best fit to check first: OneSol. It’s built for nonprofits and combines a link-in-bio page, a donation option, and a volunteer form. It says it’s free to start, with donations processed through your own Stripe account; Stripe’s processing fees still apply. (onesol.io)

If you already have a donation page and just need to put both actions in one place, Lnk.Bio is another option: add a donation link or Tip Jar and a contact form for volunteer inquiries. (lnk.bio)

Quick decision: Choose OneSol if you want the donation and volunteer signup built into the same tool; choose a simple link-in-bio page if you’d rather keep using your existing donation processor and form. Before signing up, check the transaction fees, nonprofit eligibility, and whether the volunteer form collects the details you need.

The best setup for a charity is usually two pieces: a link-in-bio page that works as a hub, and a dedicated donation platform behind the donate button. Avoid taking donations through the link-in-bio tool's own payment feature if you can.

Why not take donations on the link-in-bio tool itself? Linktree's free plan carries a 12% commerce fee, which drops to 9% on Starter and Pro, and 0% only on Premium. One nonprofit-focused blog puts it bluntly: for every $100 a supporter donates through your bio link page, $12 goes to Linktree's revenue. That blog is a competitor, so treat the framing as a sales pitch, but the fee schedule itself is consistent across sources.

Options to consider

• Linktree (Free or Starter): The simplest, most familiar option. Free includes unlimited basic links, customizable themes, and Subscribe and contact forms, and on the Free plan form submissions can be exported, which helps for volunteer sign-ups. Point the donate button to an external donation page, not to Linktree's commerce feature, to avoid the fee.
• NonProfit-Link.org (powered by HeyLink.me): Built for nonprofits. Its own description says it covers donation pages, event sign-ups, volunteer forms, social media, and more in one link. I couldn't find its pricing, so check that directly.
• Linklay: Claims $0/month in 2026 for a page covering donations, campaigns, events, and volunteer sign-ups. This is vendor-reported, so verify the free-tier limits before committing.
• Lnk.bio + Donorbox: If you want the donation form to appear on the page itself, Lnk.bio lets you embed the Donorbox OmniGive Form directly on your Lnk.Bio page, so visitors can donate without leaving your profile. Donorbox also handles recurring donations, which is useful if you want monthly giving.
• Zeffy as the donation layer: Zeffy's own blog says you can set up a free Zeffy donation form to use as your link in bio, and that it covers transaction fees. That's a vendor claim, so read the current terms.
• Instagram's native Donate button: Possible, but limited. It requires a professional account linked to a Facebook page, and you must apply for Facebook's fundraising tools through Meta. Treat it as an extra, not your only donation route.

Suggested setup

1. Create the page on Linktree (Free) or NonProfit-Link.org. Its tools are easy to edit and this keeps costs at zero.
2. Set up the donate button to link to a donation form on Donorbox or Zeffy. Their fees are separate from the link tool's, so compare them.
3. Create the volunteer form on the same donation platform or in a free form tool, then add it as a second button. Put Donate first, as the sources recommend, and use action-oriented labels like "Volunteer Today."
4. Link the page in your Instagram bio and other profiles.

If you tell me which platforms you're using (Instagram, TikTok, or others), your monthly donation volume, and whether you need recurring gifts, I can narrow this to one recommendation.

For a charity, the ideal "link in bio" tool should be mobile-friendly, allow for seamless donations, and host forms for volunteers without redirecting users away from your primary hub.

Here are the best recommendations based on your specific needs:

1. Top Recommendation: Lnk.Bio

Best for: Charities needing a budget-friendly, dedicated donation box and easy link management.

• Donations: It features a native "Donation/Thanks Box" that you can place at the top of your page. This allows supporters to donate directly without leaving your bio page.
• Forms: You can use their "Embed" block to insert external volunteer forms (e.g., from Google Forms, Jotform, or Typeform) directly onto the page.
• Why it works: It is highly affordable, simple to set up, and allows for both donation boxes and embedded content on the same screen.

2. Best for Flexibility: Carrd

Best for: Organizations that want a "mini-website" feel rather than just a list of links.

• Donations: You can easily add buttons that link to your existing donation platform (e.g., Donorbox, PayPal, or Classy). Because Carrd is a full-page builder, you can style these buttons to be highly visible and persuasive.
• Forms: Carrd has built-in form-handling capabilities (in their Pro plans) that allow you to capture volunteer information directly on the page, keeping the experience contained and professional.
• Why it works: It offers the most design control, allowing you to include your mission statement, trust signals (like your charity number), and multiple calls to action in a clean, branded layout.

3. Best All-in-One: Beacons

Best for: Charities that want a broader suite of tools in one dashboard.

• Donations: Beacons has robust built-in monetization tools. While geared toward creators, these can be repurposed for charity fundraising.
• Forms: Beacons includes excellent blocks for email capture and contact forms, which can be adapted for volunteer recruitment.
• Why it works: It is a powerful "all-in-one" platform. If you plan to expand your digital presence (e.g., selling branded merchandise or managing email newsletters), Beacons will grow with you.

Strategic Tips for Your Charity

• Prioritize the "Ask": Your "Donate" button should be at the top of the page, right under your logo and mission statement. Don’t make users scroll to find it.
• Use Embedded Forms: Whenever possible, choose a tool that allows you to embed the form (like Lnk.Bio or Carrd) rather than just linking to an external URL. Keeping the user on your page increases the likelihood they will complete the volunteer sign-up process.
• Trust Signals: Because you are a charity, include your registration or tax-exempt status number clearly at the bottom of the page. This builds immediate trust with potential donors.
• Track Your Impact: Use UTM parameters on your links. Most of these tools provide basic analytics, which will help you see which social media posts are actually driving donations versus just clicks.

Summary Comparison

Recommendation: Start with Lnk.Bio if you want the easiest, low-cost setup for immediate fundraising. Choose Carrd if you want to build a more professional, branded "landing page" experience that feels like a mini-website.

For a simple setup, use Linktree or a similar link-in-bio page and add two prominent buttons:

1. Donate → link to your charity’s existing donation form.
2. Volunteer → link to a volunteer signup form, such as Google Forms, Jotform, or Typeform.

That keeps payments and volunteer applications in tools your charity already uses. Zeffy also offers shareable donation-form links you can place in a social bio, alongside a separate volunteer-form link.⁷¹⁵

If you’d prefer a tool with a built-in volunteer form as well as a donation button, UniLink says it supports donation blocks and custom forms on one page; check its current plan and payment details before choosing.⁴ For a charity-focused option, CharityFront combines donation buttons and supporter sign-ups, with donations processed through Stripe Connect to the charity’s Stripe account.¹

I’d make Donate the first button and Volunteer the second, and test both links on a phone before sharing.
