Build powerful applications, APIs, and scalable backend systems with Reed Dynamic — based in Ann Arbor and serving businesses nationwide. If your team is copying data between systems, exporting CSVs, or fixing order errors by hand, that's a project.
Reed Dynamic's custom programming services cover API development, ERP/WMS/CRM integrations, custom backend systems, database architecture, eCommerce customization, and workflow automation — delivered by a US-based, founder-led team in Michigan.

How we approach a new integration
Map every system
Everything that touches the data — including the spreadsheets.
Decide the source of truth
Per field. This is where most integrations quietly fail.
Build the pipeline
Idempotent writes, retries, dead-letter queue.
Instrument
You see failures within minutes, not weeks.
Document
So the next developer isn't guessing.

Frequently asked questions about custom software
What kinds of integrations do you build?
eCommerce ↔ ERP (NetSuite, Acumatica, SAP B1, Epicor Prophet 21, Dynamics), eCommerce ↔ WMS, CRM sync (HubSpot, Salesforce), payment gateways, shipping (ShipStation, EasyPost), tax (Avalara, TaxJar), EDI, and custom REST/GraphQL APIs between your own systems.
How much does an API or integration project cost?
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.
How do I know if my business needs custom software?
Four signs: your team re-keys data between systems, a spreadsheet has become a mission-critical application, off-the-shelf tools require workarounds that break, or you can't get the reports you need. Read the 4 signs your business needs custom software.
Should we build in-house or hire a development company?
Hire out when the work is specialized (integrations, mobile), time-boxed, or when internal resources are already committed. Our guide covers 5 indicators it's time to engage a software development company and a self-assessment handbook.
Which technologies do you use?
Node.js and TypeScript, PHP 8 (Laravel, Magento), Python for data jobs, MySQL and PostgreSQL, Redis, AWS (Lambda, EC2, RDS, S3), Cloudflare Workers, and Docker. We pick the stack that your team can maintain, not the trendiest one.
Do you offer ongoing support?
Yes. Monthly retainers cover security patching, feature enhancements, on-call for critical integrations, and quarterly roadmap reviews.
Do you sign NDAs and BAAs?
Standard for our engagements. NDAs are signed before discovery; BAAs are signed for any project touching PHI before development begins.
