PaymentPutty replaces custom checkout development with a simple four-step wizard. Pick a starter template (or start from scratch), tell it where to appear, what should trigger it, and what it should do — your rule goes live at checkout the moment you save.
Every rule in PaymentPutty — no matter how simple or complex — flows through the same four-step wizard. Watch one come together in real time, then we'll walk through each step with screenshots from the actual app.
Here's what the wizard actually looks like inside the BigCommerce control panel. We've followed a real rule — a Minnesota road-improvement fee on shipping orders over $100 — all the way through.
Click Create Rule and PaymentPutty offers a few proven starting points: Shipping Insurance, State-Based Shipping Fee, and Donation. Each one pre-fills the wizard with sensible defaults so you can be live in under a minute. If none of them fit, choose Custom rule and you'll start from a blank wizard.
Give the rule a name your team will recognize on the orders list and inside the admin — something like "Minnesota Road Improvement Fee" — then pick which step of checkout it belongs to. PaymentPutty supports every native BigCommerce step plus the sidebar order-summary panel.
A rule can run on every order, or only when checkout state matches conditions you set. Mix and match attributes like shipping state, cart total, product category, customer group, or anything else PaymentPutty exposes — joined with AND or OR.
Pick an action type and PaymentPutty handles the rest. Available actions cover the most common checkout customization needs — messaging, custom HTML, forced acknowledgements, file uploads, form fields, and (with the Fee Engine add-on) generic fees, product-custom-field fees, and weight-based fees.
The final step changes shape based on the action you picked. For a fee, you'll set the calculation method (fixed amount or percentage), whether it's forced or optional, and where it should be inserted in the checkout layout. The name you enter here also shows up as the line item on the order itself.
Once you've seen the wizard, the only real question is what to build. Here are six rules you can recreate in a few minutes — feel free to mix the building blocks however your business needs.
Require shoppers to confirm they're 21+ before they can complete checkout on alcohol or tobacco SKUs.
Show a yellow banner reminding customers that perishable orders ship Mon–Wed only — and warn them about weekend orders.
B2B customers often need to attach an internal purchase order. Add a required form field that writes the PO to the order record.
Collect a state license photo at checkout, attached directly to the order so fulfillment can verify before shipping regulated goods.
Apply a flat $0.50 fee to Minnesota orders above $100 to cover state-mandated road infrastructure costs (the exact rule shown in our walkthrough).
Give shoppers the option to round up to the nearest dollar (or add a flat $1) for your charitable partner — opt-in, always visible.
The wizard looks the same on both tiers — what changes is which action types you can pick at Step 3. Most messaging and form-collection use cases work on Basic; anything involving file uploads, custom HTML, or JavaScript needs Pro.
Pick Basic when your rule needs to say something or ask something — messages, banners, acknowledgements, and structured form fields. No coding required, no engineering ticket.
Pick Pro when your rule needs to do something deeper — accept a file, inject custom markup or JS, or run advanced trigger logic the Basic tier doesn't expose.
These are quick examples — one rule per vertical — to show how the wizard adapts to very different businesses. For a deeper dive into any industry, visit paymentputty.com.
Trigger a flat freight surcharge whenever a vehicle bumper, tonneau cover, or other oversized SKU lands in the cart — no more guessing at checkout.
A forced acknowledgement on any cart containing wine, beer, or spirits — text and styling tuned to your brand voice.
Offer an optional in-home delivery fee for items over a weight threshold — customers opt in, and the line item shows up on the order.
Show a clear "we can't ship this product to your state" banner the moment a customer enters a restricted shipping ZIP.
A Pro-tier file upload that collects the buyer's medical license PDF and attaches it directly to the order for compliance review.
Use a Pro-tier file upload to gather customer artwork at checkout so production can start the moment the order clears payment.
