We build commerce systems, and we run one.
We run online ordering, a self-serve kiosk, POS-integrated payments and SMS loyalty on a Chicago restaurant platform we built. It takes real orders and real money every day, and your build is held to the same standard. Scope and price are fixed up front. You own everything at handoff.
Orders and payments
An e-commerce or point-of-sale system is held to a hard standard. Every order has to be correct and every payment accounted for. When something fails, the system has to say so honestly. A checkout that double-charges or a kiosk that freezes at the rush costs money and trust at the same time. So does a promotion a channel won’t honor. We engineer for that standard because our own platform lives under it.
The restaurant platform we built and run handles online ordering, a self-serve kiosk, POS-integrated payments, first-party delivery dispatch and SMS loyalty, every day in Chicago. When a payment fails mid-order on our system, the customer is refunded automatically and told the truth. Idempotent payments and ledgers that reconcile are part of that failure path, and it is the core of what we sell.
We build custom commerce where it pays for itself and integrate proven platforms where it doesn’t. Square and Toast cover POS. Headless Shopify works where a storefront fits. Custom ordering makes sense when your margins depend on owning the channel. The full services breakdown covers the engagement models.
What’s included
Online ordering & storefronts
Custom ordering platforms and headless Shopify builds, with fast, honest checkouts that convert on a phone.
POS integration
Square and Toast integration done properly: catalog sync, order routing, kitchen visibility, and reconciled payments. New POS platforms integrated on request.
Self-serve kiosks
Customer-facing kiosk software on commodity hardware. The UI is tested for the rush, and the kiosk can ride out a network drop and be recovered remotely.
Loyalty & SMS marketing
SMS engagement with points and promotions, done the compliant way. Our own loyalty platform runs live at street level.
Payments & refund integrity
Idempotent payment flows with automatic refunds on failure. The ledgers reconcile to the cent.
Delivery & fulfillment
First-party delivery dispatch with honest fee display. The kitchen sees every order, which is the part most builds forget.
How we work
- Money paths get extra checks. Anything that touches payment is tested in a sandbox and against failure, then verified against the processor before it goes live. No discount or fee goes live unverified.
- Never advertise what a channel won’t honor. Every promotion and fee is wired to what the POS and payment rails actually enforce, and pricing follows the same rule. It’s a lesson we apply from running promotions in production.
- Operations are part of the spec. We design kitchen screens and staff workflows up front, along with the edge cases at rush hour. Software that ignores the counter fails at the counter.
- The digital handoff. Code, processor accounts, catalogs, and integrations transfer to you. You own the revenue channel outright.

chaatpass.comCommon questions
Do you build on Shopify or fully custom?
Whichever your economics justify. Headless Shopify is excellent for product storefronts; custom ordering wins when third-party commissions or platform limits are eating your margin — restaurants are the classic case. We price both paths in the proposal so the decision is yours, with numbers.
Can you integrate with our existing Square or Toast POS?
Yes — deeply. Catalog sync, online-order routing into kitchen workflows, loyalty hooks, and payment reconciliation. We run a Square integration in production every day, so we know where the platform’s real edges are, not just what the docs claim.
How do you handle payment failures and refunds?
By designing the failure path first. Payments are idempotent, dispatch or fulfillment failures trigger automatic refunds, and the customer is told the truth immediately. The restaurant platform we built and run uses exactly this pattern in production — it is not theoretical.
Can you build self-order kiosks?
Yes. The kiosk we built runs on commodity Android touchscreen hardware in daily service. Kiosk work is mostly edge cases — rush-hour UI, network drops, stuck sessions, remote recovery — and that operational scar tissue is what you are hiring.
Do you handle delivery integration?
Yes — including first-party delivery dispatch, where the order, courier, fees, and kitchen visibility run through your own system instead of a commission marketplace. We run first-party dispatch in production, including the unhappy paths.
