Copy the example
An HTML order form with product options and quantities
Replace YOUR_ACCESS_KEY with the key for your payment form. Match the option values to your saved pricing rules; the price labels below are illustrative.
<form action="https://splitforms.com/api/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">
<label>Your name <input name="name" required></label>
<label>Email <input name="email" type="email" required></label>
<label>Choose a product
<select name="product" required>
<option value="small-box">Small box — $15.00 each</option>
<option value="large-box">Large box — $25.00 each</option>
</select>
</label>
<label>Quantity <input name="quantity" type="number" min="1" max="9999" step="1" value="1" required></label>
<input name="botcheck" type="checkbox" style="display:none" tabindex="-1">
<button type="submit">Continue to secure checkout</button>
</form>

Configure the server prices before accepting orders
Choose Calculate from order selections in Form settings → Payments. Add product = small-box at 15.00 and product = large-box at 25.00; use quantity as the quantity field on both rows. Set USD, tax to 0% for this example, and collect 100%.
| Form field and option value | Example full price (USD) | Amount collected |
|---|---|---|
product = small-box | $15.00 per item | 100% × quantity |
product = large-box | $25.00 per item | 100% × quantity |
Two large boxes cost $50.00 with these example prices and no tax. A posted total of $0.01 cannot replace the server-calculated amount.
For fetch() submissions, follow the returned payment_url instead of immediately showing a paid confirmation. Read the checkout integration guide.
Prices stay on the server
Submitted totals are ignored. Saved option prices, valid selections and whole quantities determine the payment.
Payments to your account
Charges are created on your connected Stripe account. Manage receipts, refunds, disputes and payouts in Stripe.
Keep the enquiry
Form acceptance and payment completion are separate. The enquiry remains available when a visitor abandons checkout.
Know the limits
A focused order form, with your own fulfillment workflow
This suits a small order form with known options. It does not provide stock tracking, shipping-rate calculations, discount-code management or a full store. Use a commerce platform when you need those capabilities.
- One-time payments through hosted checkout
- Separate payment and mailing-list forms
- Confirm paid status before fulfillment

Common questions
Frequently asked questions.
View all FAQsCan each order have a different payment amount?
Yes. Save a price for each form option and optionally name its quantity field. SplitForms calculates the total on the server from the selected options and quantities, then creates a Stripe Checkout session for that amount.
Can I use this on Netlify, Vercel or a static HTML site?
Yes. A native form posts to SplitForms and redirects to Stripe Checkout. With JavaScript fetch(), read the JSON response and navigate to payment_url. You do not need a Stripe secret key on your website.
Can I use checkboxes for add-ons?
Yes. Add option prices for the add-on field and submit selections as an array or repeated form fields. Distinct selected options are summed once. The first configured field is required; later groups can be optional.
Does SplitForms calculate shipping or track stock?
No. The order calculation uses the option prices, quantities and tax percentage you configure. Shipping rules, inventory and fulfillment remain your responsibility.
Is a paid plan required?
Yes. Form payments are available on paid SplitForms plans. Stripe processing fees are separate. Connect an eligible Stripe account, complete any requested verification and test the checkout before taking customer payments.
