**Reed Dynamic provides custom software services to businesses in Detroit, Michigan** from our office in Whitmore Lake, about 50 miles away. We serve Detroit companies in automotive & mobility, fintech & mortgage lending, manufacturing & logistics, and more — with on-site discovery, training, and support.

## About doing business in Detroit

Detroit is the center of the North American automotive industry and a rapidly redeveloping downtown and Midtown — corporate headquarters, fintech and mortgage lenders, TechTown and university-affiliated startups, sports and entertainment districts, and a resurgence of neighborhood retail and restaurants. The city's business community spans hundred-year-old manufacturers and two-year-old software companies.

Detroit engagements are frequently enterprise-adjacent: SharePoint and Microsoft 365 modernization for large organizations, custom middleware between legacy manufacturing systems and modern eCommerce, mobile apps for field or logistics operations, and Magento 2 for brands scaling direct-to-consumer. We work on-site in downtown and Midtown regularly.

### What local search looks like in Detroit

Detroit searches split between enterprise procurement (RFP-driven, credentials-focused) and neighborhood businesses (map-pack-driven). We structure content so both find what they need: compliance and case studies for the former, hours, phone, and reviews for the latter.

## Custom Software FAQs for Detroit businesses

**

### How much does a custom integration cost for a Detroit company?

**

Small point-to-point integrations start around $5,000. Larger middleware or multi-system orchestration typically runs $20,000–$75,000 depending on data volume, error-handling requirements, and how much of the legacy system needs to be reverse-engineered.

**

### Do you work on-site in Detroit?

**

Yes. We're about 50 miles away in Whitmore Lake, so on-site discovery and cutover support are standard. Every project has a shared Slack or Teams channel and weekly demos.

**

### Which ERPs do you integrate with?

**

NetSuite, Acumatica, SAP Business One, Epicor Prophet 21, Microsoft Dynamics, QuickBooks, and custom or legacy ERPs; plus shipping (ShipStation), tax (Avalara, TaxJar), CRM (HubSpot, Salesforce), and payments (Stripe, Authorize.net).

**

### Do you provide ongoing support after launch?

**

Yes. Monthly retainers cover security patching, feature enhancements, on-call for critical integrations, and quarterly roadmap reviews.
