Square App Marketplace check
Each channel tested against Square's own integrations before we quote, from delivery apps to accounting.
The Problem
When Every Order Channel Runs on Its Own Tablet
A Square integration usually gets ordered during a busy week. Delivery tablets pile up, the website oversells, and the accountant asks again where the fees went.
01 · Tablets
Staff retype delivery orders from three different tablets.
DoorDash, Uber Eats, and Grubhub orders arrive in Square's kitchen display.
02 · Menus
Delivery apps still sell items you removed on Monday.
Menus, prices, and availability sync to each delivery app from Square.
03 · Stock
The website sells items the store already sold out.
Inventory syncs between Square and your website whenever stock changes.
04 · Books
Your accountant can't see the fees inside Square deposits.
Square sales post to QuickBooks Online or Xero with fees separated.
Your counter has a tablet for DoorDash, another for Uber Eats, and staff retype every order into Square. The menu changes on Monday, but the delivery apps still sell Friday's special. Your website sells items that ran out in the store hours ago. Square deposits arrive in one lump, and your accountant asks for the fee breakdown again. Customer emails sit in Square and don't reach your newsletter. Every channel works on its own, and none of them talk to each other.
We start by checking what Square already connects through its App Marketplace, because many delivery and accounting links are built in. We switch those on and map your menu, modifiers, and taxes properly. Where a channel needs more, we build on the Square API, with catalog IDs stored on both sides and webhooks that keep stock and orders current. Orders land in Square, not on a stack of tablets.
Square's own apps first
Built-in DoorDash, Uber Eats, Grubhub, and accounting integrations are checked before any custom code.
One screen for every order
Delivery and website orders land in Square, so staff work from one queue in the kitchen.
Stock that stays honest
Catalog IDs on both sides keep website stock in step with in-store sales.
Our Square Integration Services Process
From Setup Review to One Order Queue in Five Steps
You see which channels Square already covers, approve the menu and order map, and watch test orders reach the kitchen before anything goes live.
We check which Square plan and features you run, then test what Square's own App Marketplace integrations already cover for your channels. You get a written answer per channel: switch on the built-in integration, or build on the Square API.
What's Included
What a Square API Integration Covers
Each project mixes built-in Square apps with custom code where it's needed. These six parts cover everything from the first channel to a multi-location build.

DeveloperLook vs Built-in App vs Freelancer
Square's built-in apps are free or cheap and switch on fast, and a freelancer can fix one plugin. Here's where each holds up as channels and locations grow.

|---|---|---|---|
| Setup review | Every channel checked first | Install and hope | Varies by person |
| Menu mapping | Modifiers and taxes mapped | Default mapping only | Often partial |
| Delivery apps | All apps into Square | One app per install | Depends on their skills |
| Website stock | Synced with a set owner | Plugin default direction | Manual updates |
| Accounting | Fees, tax, and payouts mapped | Summary posting on some apps | Rarely included |
| Speed to start | 1 to 7 weeks | Same day for common apps | Days to weeks |
| Ownership | Your Square account and code | Your Square account | Sometimes their accounts |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites and business software for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Restaurants and Shops Trust Us With Square
Your till takes the money, so mistakes cost real sales. These habits keep orders flowing, menus accurate, and every change easy to roll back on a busy night.
Square apps before code
We check Square's App Marketplace and your plan before pricing custom work. If a built-in integration already covers your channel, we'll tell you before we quote.
Modifiers mapped properly
Sizes, add-ons, and combos are mapped item by item, not flattened into one line. Your kitchen sees the same order the customer built.
Switchovers on quiet shifts
We switch channels over during your slowest service, one at a time. A problem shows up on a few orders, not in the middle of a Friday rush.
Rate limits respected
Our code backs off when Square returns a rate-limit error and uses batch endpoints for big catalogs. Your sync slows down instead of dropping orders.
Duplicate events ignored
Square can send the same webhook more than once, so we record each event ID before acting. A repeated event doesn't create a second order or stock change.
Credentials stay yours
Square access tokens, app credentials, and code belong to your business. Changing developers later doesn't mean reconnecting every location from scratch.
Overview
Who sets up Square integration for restaurants and shops?

Good fit
Restaurants juggling delivery tablets
Your counter has a tablet for each delivery app. You want the Square DoorDash integration and Square Uber Eats integration sending orders to one kitchen screen.
Shops selling online and in store
Your shop sells in person on Square and online through WooCommerce or WordPress, and stock counts drift apart by the weekend.
Owners whose accountant uses QuickBooks or Xero
Your accountant wants Square sales in QuickBooks Online or Xero, and you need a Square QuickBooks integration that posts fees, tax, and payouts correctly.
Cafes building a customer email list
Your cafe collects customer emails at the till, and you want a Square Mailchimp integration or Square Klaviyo integration that turns purchases into campaigns.
Software teams building for Square sellers
Your app serves many Square sellers, and you need the Square POS API wired through OAuth, catalog sync, and webhooks without touching sellers' other data.
Not a fit
Shopify store, Square till
Your online store runs on Shopify and Square is the in-store till. Our Shopify Square, Clover and Lightspeed Sync page covers that pairing.
Toast, Clover, or Lightspeed till
Your restaurant runs Toast, Clover, or Lightspeed rather than Square. Our POS Integration Services page covers those systems.
Salon booking on Vagaro
Your salon books appointments and takes payments in Vagaro. Our Vagaro Website Integration Services page covers that setup instead of Square.
Budget under $800
Your budget is under $800 and you need one delivery app with a simple menu. Square's own App Marketplace setup covers that, and we'll tell you before we quote.

Frequently Asked Questions
Straight answers on Square costs, website setups, delivery apps, and how Square connects to QuickBooks, Xero, and WooCommerce.
Saimul IslamFounder & CEO, DeveloperLookStill have questions?
Send a message or book a call with the team.
Square integration services with DeveloperLook start at $800 for one location connecting its website or one delivery app. That covers menu mapping and test orders. Custom syncs on the Square API with books or marketing start at $2,300, and multi-location or multi-seller builds start at $4,900. Square and delivery app fees are separate, and our fixed quote follows a free Square setup review.
Yes. Square offers several routes. Square Online is a hosted site, and buy buttons or Payment Links drop into an existing site. Square for WooCommerce suits WordPress stores, and the Web Payments SDK fits a custom checkout. The right one depends on whether you need a full store, a few products, or payments inside your own app.
For a custom site, you add Square's Web Payments SDK to the checkout page, which turns the card into a single-use token. Your server sends that token to the Payments API to take the payment, so card numbers stay off your server. For a few products, a buy button or Payment Link pasted into the page is simpler.
Yes. Square lists a direct DoorDash integration in its App Marketplace for Square for Restaurants and Square POS restaurant modes, in the US, Canada, and Australia. It sends DoorDash orders into Square and syncs menus, hours, prices, and availability. You need a DoorDash account and a Square menu first, and we map modifiers so the kitchen reads each order correctly.
Yes. Square's Uber Eats integration syncs menus, prices, photos, and item availability, and routes orders to your POS and kitchen display. It works with Square for Restaurants or Square plans with restaurant features, in markets including the US, UK, Canada, Australia, and Ireland. We set it up per location and test a live order before your next busy service.
Yes. Square's Xero integration, built by its partner Amaka, posts a daily sales summary or one invoice per order, along with tips, taxes, refunds, and fees. It also helps match deposits during bank reconciliation. We map it to your Xero accounts, then check a week of sales against Square's own reports before your accountant relies on it.
Yes. Square for WooCommerce is a free extension that takes Square payments and syncs products, inventory, and customers. You choose whether WooCommerce or Square is the source of truth for product data, while stock from in-store sales still flows to the website. We set the direction, clean up SKUs on both sides, and test with real orders.
Yes, even without WooCommerce. You can paste Square buy buttons or Payment Links into any WordPress page, and Square hosts the checkout. Square doesn't document a separate WordPress plugin outside WooCommerce. When a payment needs to create a booking, a member account, or a form entry in WordPress, we build that link on the Square API.
No, Vagaro doesn't document a Square integration, because it runs its own payment processing through Vagaro Merchant Services. Salons usually pick one system for booking and payments. If Vagaro is your system, our Vagaro Website Integration Services page covers connecting it to your site, and we'll compare both setups honestly before you switch.
You connect Square Connector by QuickBooks, Intuit's free connector for QuickBooks Online subscribers. It imports Square sales, fees, sales tax, adjustments, and payouts within a few hours. Some setups need location classes or item rules the connector can't handle. For that kind of Square QuickBooks integration, we build the sync on both APIs and test it against a month of sales.
