01 — LIMIT OF READY APPLICATION

Where are ready-made apps not enough?

There are thousands of apps available in the Shopify App Store, but at some point, growing brands reach the limit of ready-made solutions. Paying separate subscription fees for several applications that do the same job, working with too many scripts that slow down the site, or the failure of any application to meet a brand-specific business rule are the most common signs of this limit.

Custom app development is the development of applications designed from scratch according to the needs of your brand and integrated into the Shopify administration panel or storefront. Product personalization, special discount and campaign setups, B2B pricing, loyalty systems or brand-specific management screens can be developed in this context.

04 — PRIVATE APP

Private app is an expression used for applications that work only in your own store and are not published in the App Store. Starting from 2022, Shopify removed the old private app structure and replaced it with the "custom app" model created through the management panel. Today, store-specific applications are designed using this model with secure access keys with limited privileges.

It is important for store security and sustainability to move the integrations working with the old private app structure to the current model, limit access permissions to only the required fields, and follow API version updates. We develop these applications for your store's specific needs and safely update existing structures.

05 — API INTEGRATIONS

Shopify API integrations

Shopify API integrations are solutions developed to enable your store to communicate with external systems that do not have ready connections. With Admin API, product, order, stock and customer data are managed. With Storefront API, different storefronts such as mobile applications or headless structures are connected to the Shopify infrastructure, and with webhooks, events taking place in the store are instantly transmitted to other systems.

In integrations with WMS, CRM, B2B portal, dealer systems or in-house software, data matching, API usage limits and error management determine the success of the project. That's why we set up each integration with registration, notification and retry mechanisms to work smoothly in the long run.

06 — AUTOMATION APP

Shopify automation apps are applications that automate repetitive manual tasks in store operations. Tasks such as labeling orders according to certain conditions, separating risky orders, sending notifications to the team when the stock is low, segmenting customers according to their expenses, or automatically adding products to collections can be automated in this context.

While quick solutions are established with Shopify Flow in simple scenarios, we develop brand-specific automation applications for complex business rules where Flow is not sufficient. Correctly designed automations enable the team to allocate their time to growth instead of operations.

07 — DECISION

Ready application or custom development?

It is not necessary to develop a special application for every need. In some cases, a properly configured ready-made application is the fastest and most economical solution. However, custom development becomes more efficient in the long run when multiple applications do the same job piece by piece, monthly subscription costs increase, or your business rules do not fit into ready-made solutions. fits
