Arefin Khan
About this gig
Need a custom inventory management web app that matches how your business actually works?
I build responsive inventory systems using React, Next.js, TypeScript, Supabase, and PostgreSQL. My experience includes a deployed retail inventory and POS system with SKU tracking, barcode workflows, sales history, returns, expenses, commissions, reconciliation, and reporting.
I can build:
- Product, category, SKU, and stock management
- Stock-in, stock-out, adjustments, and low-stock alerts
- Supplier and purchase workflows
- Sales, returns, and POS functionality
- Secure authentication and user roles
- Dashboards, reports, and PDF exports
- Barcode, payment, or third-party integrations
Package scope:
- Basic: One defined inventory module
- Standard: Inventory MVP with core workflows
- Premium: Multi-role business inventory system
Data migration, POS, barcode printing, payment integration, multi-branch support, and other advanced modules require confirmation or a custom offer.
Please message me before ordering. Share your current process, required modules, user roles, reports, integrations, and deadline.
I will review the scope and recommend the correct package.

FAQ
Should I message you before ordering?
Yes. Inventory systems vary by business workflow. I will review your modules, roles, reports, integrations, and deadline before confirming the correct package.
Does the Basic package include a complete inventory system?
No. Basic covers one clearly defined inventory module with up to two pages. Choose Standard, Premium, or request a custom offer for a larger system.
What information do you need to start?
Your current inventory process, required modules, user roles, reports, integrations, design references, sample data, and preferred deadline.
Can you improve an existing inventory application?
Yes. I can add features, fix workflows, improve performance, or modernize an existing system after reviewing its codebase and current setup.
Which technologies do you use?
My primary stack is React, Next.js, TypeScript, Supabase, PostgreSQL, Node.js, and Tailwind CSS. The final stack depends on your requirements.
Are POS and barcode features included?
They are not included automatically. POS checkout, barcode generation, thermal printing, and scanner integration must be confirmed before ordering.
Is existing data migration included?
No. Data migration requires a sample of your spreadsheets or database so I can assess cleaning, mapping, validation, and migration effort.
Is deployment included?
Deployment is included in Premium. For Basic or Standard, deployment can be included through a custom offer after reviewing your hosting requirements.
Will I receive the source code?
Yes. Source code is included in every package after the order is completed.
Can you provide ongoing development and maintenance?
Yes. After the first delivery, additional modules, integrations, improvements, and maintenance can continue through scoped custom offers.
