Custom Retail POS System Development

# Senior POS Developer / Architect Needed – Custom Retail POS Platform

I am looking for an experienced **POS software developer or development team** to build a custom retail Point-of-Sale system from the ground up.

The initial system will be used in my own retail stores, but the long-term goal is to develop this into a **commercial POS platform that can eventually be offered to other businesses**.

### General Requirements

The system should include:

* Modern, fast retail POS interface
* Product and inventory management
* Barcode scanning
* Employee accounts and permissions
* Cash register management
* Sales, returns, refunds and discounts
* Customer management
* Receipt printing
* Reporting and analytics
* Multi-store support
* Cloud-based administration
* Reliable synchronization between locations/registers
* Integration with POS hardware such as barcode scanners, receipt printers, cash drawers and payment terminals

### Payment Processing

A major part of the project will be **integrated credit/debit card processing**.

I want the POS to communicate directly with a compatible payment terminal so the cashier can initiate a transaction from the POS and the customer can tap/insert/swipe their card on the terminal.

The payment architecture should be flexible enough to potentially support **multiple payment processors in the future**.

Long term, I am interested in developing a business model where the platform could potentially generate revenue through:

* POS subscriptions
* Hardware
* Payment processing
* Additional software/services

Experience with payment processors such as **Square, Stripe, Adyen, Fiserv, Worldpay, Global Payments, Clover**, or similar platforms is highly desirable.

### Long-Term Architecture

The system should be designed with future growth in mind, including:

* Multiple businesses/merchants
* Multiple locations
* Multiple registers
* Cloud administration
* Multi-tenant architecture
* Payment integrations
* Merchant onboarding
* Third-party integrations
* Scalable infrastructure

### Development Approach

I would like to begin with a **paid discovery/architecture phase**.

I will provide an existing POS system as a **functional reference** so the developer can understand the type of workflow and functionality I am looking for.

The first phase should determine:

* System architecture
* Technology stack
* Database structure
* Payment architecture
* Hardware integration
* Development roadmap
* Estimated cost and timeline

After the architecture phase, I would like to move into full development with the right developer/team.

### Who I Am Looking For

I am specifically looking for someone with **real-world POS development experience**, not just general web development.

Ideal experience includes:

* Retail POS
* Inventory systems
* Payment processing
* Payment terminals
* POS hardware
* Multi-location systems
* Cloud/SaaS platforms
* APIs
* Multi-tenant applications
* Security and payment compliance

Please provide examples of **POS systems you have personally built or worked on**, including any payment terminal integrations.

I am looking for a **long-term development partner**, not just someone to complete a quick project.
