Square integration
Square is the card reader that turned into a full payments company. Connect the Square account you already use in your shop or at a market stall, and take the same payments online through a TinyVendor sell link.
About Square
Square is the payments and point-of-sale business built by Block, Inc. — the company Jack Dorsey and Jim McKelvey started in 2009 after McKelvey lost a sale he couldn't take a card for. It was named Square, Inc. until the 2021 rename, and is headquartered in San Francisco.
Headquarters
San Francisco, California, United States.
Founded
2009, by Jack Dorsey and Jim McKelvey.
Parent company
Block, Inc., publicly traded, formerly named Square, Inc.
Known for
In-person card readers and point-of-sale hardware, alongside online payments for small and medium businesses.
Square tends to suit sellers who already sell face to face — at a counter, a market, or a pop-up — and want the same account handling the online side too, rather than juggling two separate payment setups.
How to apply for a Square account
1. Sign up online
Square is built for self-service signup rather than a branch visit or relationship manager. Create an account with your email on Square's signup page.
2. Describe your business
Give your legal business name (or your own name if you're a sole proprietor), your industry, and roughly how much you expect to sell.
3. Verify your identity
Square asks for a Social Security Number or an EIN, along with personal details, to meet its know-your-customer requirements.
4. Link a bank account
Add the bank account where you want Square to send your payouts.
5. Create a developer application
Separately from seller signup, open a Square Developer account and create an application in the Developer Dashboard. That's where you'll find the access token, location ID, and application ID that TinyVendor needs.
6. Start processing
Most straightforward small-business applications are approved quickly. Square may hold an account for manual review if the business type or expected volume needs a closer look. Note that Square operates as an aggregated merchant account rather than issuing you a dedicated one — part of why signup is so fast.
Selling with Square on TinyVendor
If you already use Square, connecting it to TinyVendor takes a few minutes and no code.
1. Get your Square credentials
In the Square Developer Dashboard, open (or create) an application and copy its application ID and access token. In your Square Dashboard, open Locations and copy the location ID you want payments sent to.
2. Add Square as a gateway in TinyVendor
In your TinyVendor dashboard, go to payment settings, choose Square, and paste in the access token, location ID, and application ID. There's nothing to install and no server to configure.
3. Create a sell link
Set a title, description, and price for whatever you're selling, and choose Square as the payment option. You can offer it alongside other gateways on the same link.
4. Share the link
Post it, message it, or drop it in a bio link — all from your phone if that's what you have handy. There's no hosted checkout page for you to build or host yourself.
5. Get paid
When a buyer pays, Square processes the card charge under your existing Square account. Card details never touch TinyVendor's servers or your own — Square handles that, so you carry no PCI compliance scope.
6. See the order
The order appears in your TinyVendor dashboard right away, alongside the matching transaction in your Square dashboard.
Questions
What does TinyVendor charge on top of Square's processing fees?
2% of a sale on the Basic plan, 1% on Pro and 0.5% on Max, with no monthly fee and nothing to pay in a month with no sales. Square charges its own processing rate separately.
What Square credentials does TinyVendor need?
TinyVendor asks for your Square access token, location ID, and application ID, all of which come from your Square account and the Square Developer Dashboard.
Do I need to write any code to sell with Square on TinyVendor?
No. You create a sell link in TinyVendor and paste in your Square credentials — there's no checkout page or integration code to build.
