FastrrCheckout
Built for Indian Shopify stores

Checkout in one screen, not five steps.

Every extra page between the Buy Now tap and a paid order is a place to lose the sale. Fastrr Checkout collapses the whole thing into a single mobile-first screen — phone, address, payment — and writes the order straight into your Shopify admin.

The drop-off happens between the tap and the payment

A shopper who reached your product page already wants the product. What loses them is everything that comes next.

Too many screens

Cart, contact, shipping, payment — four page loads on a phone with two bars of signal, each one a chance to give up.

Accounts nobody wants

A sign-up form in front of a ₹600 order asks the shopper to commit before they have bought anything.

Address typed out in full

House number, street, area, landmark, city, state, PIN — on a phone keyboard, one field at a time.

How it works

Four steps, one screen, no page reloads

The shopper never leaves the checkout until the payment sheet opens. Everything below happens in place.

  1. Phone number

    Optionally verified by a WhatsApp OTP. Returning shoppers are recognised and their saved address is filled in.

  2. PIN code

    City and state fill themselves from the PIN, and address autocomplete finishes the rest from two or three words.

  3. Payment method

    UPI, cards, net banking, wallets or Cash on Delivery — whichever you have switched on.

  4. Order placed

    The order is written to your Shopify admin with stock adjusted, and the shopper sees the confirmation.

What you get

Everything the checkout needs, already built

Every Indian payment method

UPI, cards, net banking and wallets through Razorpay, Cashfree or PayU — plus Cash on Delivery with your own rules.

WhatsApp OTP login

Verify a shopper on the number they already use, without an SMS gateway or a password.

Address autocomplete

Two or three words and the address is picked from a list. The provider key stays server-side and never reaches the browser.

COD, controlled

Charge a COD fee, set a minimum or maximum order value, or require an OTP before a COD order is accepted.

Abandoned cart recovery

Every checkout that opened and never paid, with the phone number and a one-tap WhatsApp link to follow up.

Revenue analytics

Revenue over time, conversion, the split by payment method and gateway, and why failed payments failed.

Orders stay in Shopify

Orders are created in your Shopify admin with inventory adjusted, so your existing fulfilment carries on untouched.

Refunds from one place

Issue a full or partial refund against the original payment, with the history kept beside the order.

Yours to brand

Set the logo, the colours and the corner radius, and the checkout looks like the rest of your store.

Money and data

Your gateway. Your money. Your customers.

Fastrr Checkout never sits between you and your settlements. Payments run through your own gateway account, so the money reaches your bank on your gateway's schedule — not ours.

Card details are entered in the gateway's own sheet and never touch our servers.

Prices and totals are resolved server-side from Shopify, so nothing in the browser can change what is charged.

Every gateway callback is verified by signature before an order is marked paid.

Each store's orders, customers and credentials are isolated from every other store.

Shopify's privacy webhooks are handled: data requests, customer redaction and shop erasure.

TLS everywhere

The checkout, the admin and every callback are served over HTTPS only.

Signature-verified

Shopify webhooks by HMAC, gateway webhooks by the gateway's own hash.

Tenant-isolated

A store's data is resolved from its own session, never from the URL.

Audited timeline

Every payment, refund and status change is recorded against the order.

Common questions

Does this replace my Shopify checkout completely?
It sits alongside it. Fastrr Checkout adds a Buy Now button to your product pages that opens the one-page checkout; the standard Shopify cart and checkout stay exactly where they are, so nothing breaks for a shopper who prefers them.
Do my orders still appear in the Shopify admin?
Yes. Every paid order is created in your Shopify admin with the inventory adjusted, so fulfilment, shipping apps and your accounting carry on exactly as before. Nothing about your existing workflow has to change.
How long does setup take?
Installing from Shopify and connecting a payment gateway takes a few minutes. The Buy Now button is added to your theme automatically during install, so there is no code to paste and no developer to book.
Will it match my store's design?
You set the logo, the primary colour and the corner radius in the app settings, and the checkout picks them up on the next page load. The layout itself stays fixed — it is the part that is tuned for conversion.
Who holds the money?
You do. Payments run through your own Razorpay, Cashfree or PayU account, so settlements reach your bank on your gateway's normal schedule. We never take custody of your funds and we are not in the settlement path.
