Replacing Manual B2B Order Processing with Dedicated Portals

Handling wholesale orders via emails and phone calls wastes significant administrative hours and creates fulfillment errors. A modern B2B customer portal automates the entire wholesale sales cycle.

A custom B2B portal typically delivers full return on investment (ROI) within 6 to 9 months by eliminating manual order entry overhead.

Frequently Asked Questions (FAQ)

Is the estimated project budget binding?

The price range represents an accurate estimate based on completed production implementations. Following an initial architecture consultation, I prepare a fixed-price milestone specification for your MVP.

Who retains ownership of the source code and intellectual property?

100% of the source code, Git repositories, and intellectual property belong exclusively to your company. I charge zero hidden recurring licensing fees or transaction commissions.

How long does it take to design and launch an MVP?

Using proven architectural patterns and Flutter / Next.js, I typically deliver the first fully functional production version within 6 to 10 weeks.

Do you offer ongoing SLA maintenance after deployment?

Yes, I provide dedicated SLA technical support covering proactive monitoring, dependency updates, and guaranteed response times.
