Custom Shopify apps and integrations

Péci Ltd. builds custom Shopify apps, theme app extensions, web pixels and integrations for merchants and agencies. We also build and ship our own Shopify apps: Persistent Cart is live on the Shopify App Store, Revenue Radar is in review, and PageSmith is built but not yet submitted. We have taken our own app through Shopify App Store review and have a second one in review now, so we work across the whole path: the Shopify APIs, extensions, billing, the GDPR webhooks and the review requirements.

Packages

Shopify app and integration audit

400 USD, fixed

We look at a Shopify app, an integration or a bug that is costing you time, and you get a written report from a company that has taken an app through Shopify App Store review: what is wrong, and what to do about it.

Custom feature

from 1,500 USD

A checkout or theme app extension, a Shopify Function, or one outside system connected to your store.

Custom app

from 3,000 USD

An app built for one store, from the first design to launch.

What you get

  • The code is yours once the project is paid in full.
  • It runs on your own Shopify and hosting accounts. We never ask for your password, and the scope lists every running cost.
  • 50% to start, 50% after you accept it on a development store.
  • 30 days of free fixes after launch.

For agencies: we can work under your brand, in your repository and Partner organization, and sign your NDA. We are in Hungary (CET).

Services are for businesses. Prices are in USD and exclude VAT, which is added where it applies. A project starts only once we both agree to its written scope.

How it works

  1. Email us what you need. A few sentences are enough.
  2. You hear back within two business days. A written scope and a fixed price usually follow within the same time.
  3. We build and test it on a development store, then hand it over with short documentation.

Live on the Shopify App Store

Persistent Cart

Shoppers who switch from phone to laptop find an empty cart and may not rebuild it. Persistent Cart keeps the cart with the logged-in customer, so it follows them to any device, and lets shoppers or your team share a ready-made cart by link.

Built with: theme app extension, Web Pixel extension, React Router and Polaris, PostgreSQL
