Web Development Review from Kirill Kudymov
Oyova designed and developed a web platform that allows users to access and post information relating to MS. Without wireframes, their team developed much of the design on their own, taking into account that the interface needed to be very user-friendly for our audience.
Brittany Grunzinger's Review Sourced from Google
Oyova has continuously proven to be a fantastic partner to our team! They are knowledgable, easy to work with, and come to the table ready to collaborate. When seeking a business relationship, the hope is always that it’s seamless, and that’s exactly the experience we’ve had with them. Whether we have a simple question or a complex need, they remain a team that we can rely on. My primary point-of-contact is Beth, and she’s been wonderful! She’s not only great at keeping things on track, she’s also kind and approachable. In fact, I’ve collaborated with multiple members at Oyova and everyone has made it easy to build a long-term, trusting relationship with them. If you have the chance, work with them. You’ll be glad you did!

ivy on Milopeco909's Review Sourced from Google
I highly recommend Isaac with Techy Toes! I’ve been blessed to have found Isaac and received his services to help promote our plumbing business in Arizona. Within the first 6 months of help Isaac not only had provided us with a fully functioning website but also had worked his magic in getting us to become visible on Google. We have held one of the top three spots in our city on Google Maps for the past 4 years now. The past three years we were awarded the best plumbing company in our city from 3 separate plumbing magazines. We would never have been able to accomplish what we have so far without Isaac. We highly recommend his SEO, Website, and other business related services. He is very honest, patient, and hard working. He will always receive our honor and gratitude for his dedicated hard work and patient understanding. Thank You Isaac and Techy Toes.
Ramsina Herrington's Review Sourced from Google
I am very satisfied with Techy Toes Services. Isaac with Techy Toes was able to help make my company, All Drains Emergency Plumbing in Glendale, Arizona one of the top plumbing companies in our city. He was not only able to get our Google Business profile approved for Google, but he was also able to make us visible on Google Maps ascertaining us one of the top three spots on Google Maps in our city which has directly related to our company’s success including giving us a chance to win multiple top plumbing company awards in our city. I will never replace him with another marketer. He is a key core to our company and its continued success. If you are a new company looking for SEO services or help with your website or Google Profile, or Apple profile, or voice search platforms, Isaac with Techy Toes can help tremendously and he is very fair with his pricing. Thank You for all your continued help Isaac! I highly recommend his services.

Hiring Guide: How to Choose the Top eCommerce Agency in the US
What can the top eCommerce development companies in the US do for businesses?
Top eCommerce companies in the US help businesses build scalable, high-performing online stores that are designed to grow revenue while reducing operational complexity.
They improve user experience and site performance, which directly supports higher conversion rates, faster load times, and better checkout completion.
These agencies also structure product catalogs and backend systems, so businesses can manage larger inventories without friction.
The result is a measurable impact across key KPIs such as higher average order value, lower customer acquisition cost, improved retention, and reduced return rates, allowing teams to scale efficiently without increasing overhead.
According to industry research, eCommerce will account for 22.6% of all global retail purchases by 2027.
Moreover, 63% of consumers will buy directly from a business website, showing that an effectively developed eCommerce platform is a potential growth driver for many brands.
In fact, eCommerce websites can boost conversion rates by over 35%.
What's the cost of hiring eCommerce development agencies in the United States?
The costs of hiring an eCommerce agency range from $100-$200 per hour or $25,000-$250,000+ per project for comprehensive end-to-end development.
The final price will depend on platform type, store complexity, customization level, number of pages, core features and functions, integration and security requirements, and service scope.
Here is a more detailed pricing breakdown:
| Project Type | Estimated Cost | What is Included |
| Simple store development | $5,000-$20,000 |
|
| Mid-sized build | $25,000-$80,000 |
|
| Headless eCommerce | $30,000-$50,000 |
|
| Enterprise build | $100,000-$250,000+ |
|
What is the typical process when working with an eCommerce agency?
Most eCommerce agencies follow a structured workflow designed to reduce risk and deliver predictable outcomes from planning through optimization. Here are the typical process and approximate timeframes of an agency:
- Research and discovery (2-4 weeks): The agency learns about business goals, customers, competitors, KPIs, technical requirements, and project scope. Deliverables typically include a discovery summary, high-level recommendations, a detailed scope, timeline, and cost estimate.
- UX and UI design (4-6 weeks): User journeys, wireframes, and visual designs are created to optimize conversion and usability. Deliverables include wireframes, design mockups, and design system components.
- Development (8-20+ weeks): The store is built on the chosen platform with custom features, configurations, and system integrations. Clients usually get access to a staging site, system documentation, validated data imports, and regular progress updates.
- QA and testing (2-4 weeks): The site is tested for functionality, performance, security, and cross-device compatibility. Clients receive a test plan, bug reports, and fixes prior to launch.
- Launch (1-2 weeks): The site goes live following final checks and deployment. Deliverables include launch checklists and go-live confirmation.
- Post-launch support and optimization (ongoing): Agencies monitor performance, fix issues, and improve conversions. Ongoing deliverables may include reports, optimization recommendations, and maintenance documentation.
What common mistakes should I avoid when hiring an eCommerce development company?
Common mistakes to avoid when hiring an eCommerce agency include:
- Choosing based on visuals only: A polished design does not guarantee strong performance, scalability, or code quality. Instead, look for companies that have driven measurable business outcomes for clients and have strong development experience as well as design skills.
- Not defining scope, goals, and KPIs: Unclear requirements often lead to missed deadlines, budget overruns, and misaligned expectations. As such, it is best to specify your target customers, tech stack, core features and functions, key success metrics, business goals, budget constraints, and project timeline.
- Ignoring platform expertise and migration risk: Lack of experience with your platform and industry can result in data loss, noncompliance, or prolonged operational downtime.
- Overlooking QA testing and post-launch support: Insufficient testing increases the risk of checkout failures, bugs, security vulnerabilities, and customer frustration.
- Not clarifying ownership of code, themes, and accounts: Unclear ownership can limit flexibility and create long-term dependence on the agency. It can also inflate costs as the project becomes increasingly unscalable.

Frequently Asked Questions About eCommerce Companies
What services do eCommerce development companies in the United States offer?
US eCommerce development companies typically offer:
- Custom eCommerce website development: Builds storefronts, themes, and commerce functionality (catalog, pricing, promotions, checkout, customer accounts) plus required backend services.
- Platform migration and re-platforming: Moves products, customers, orders, content, and SEO signals with testing and cutover planning to minimize downtime and revenue risk.
- Custom eCommerce design: Creates brand-aligned UI/UX, information architecture, and conversion-focused user flows for product discovery, cart, and checkout.
- Catalog setup and merchandising foundations: Includes product data modeling, category structure, search configuration, and tooling for merchandising and promotions.
- Systems integration: Connect payments, tax/shipping, ERP/OMS/WMS, CRM, analytics, marketing automation, and other third-party tools.
- Security and compliance: Implements security best practices like SSL/PCI compliance.
- Maintenance and ongoing optimization: Provides ongoing updates, testing, and improvements, such as the page load speed and checkout flow, to improve success metrics and ensure the eCommerce store performs optimally.
What’s the difference between an eCommerce development company and an eCommerce marketing agency?
eCommerce development companies focus on building, optimizing, and maintaining the online store itself, while eCommerce marketing agencies typically concentrate on marketing, growth, and customer acquisition across channels.
| Agency type | Primary focus | Typical deliverables |
| eCommerce development | Store architecture, performance, UX, and integrations | Website builds, platform setup, custom features, checkout optimization, integrations, migrations, maintenance |
| eCommerce marketing | Marketing strategy and demand generation | SEO, paid ads, social media, content, email marketing, branding |
What kind of ROI can I expect from an eCommerce agency?
A well-developed and designed eCommerce store delivers an average ROI of 10%-30%.
However, the return on investment depends on your goals, platform type, target markets, business benchmarks, success metrics, and ongoing marketing strategies.
For instance, a Shopify fashion brand has an average conversion rate (CVR) of 1.6%-1.9%. But home electronics see higher returns at a CVR of 3%-3.6%, while the beauty and personal care sector experiences an average CVR of 6.5%-6.8%.
Here are the general global benchmarks of eCommerce store development and optimization:
- Conversion rate: 1-2%
- Average order value: $50-$100
- Cost per click: Below $1
- Cost per acquisition: Below $25
How long does it take to build an eCommerce website?
The time required to build an eCommerce website depends on scope, platform, content volume, and the number of integrations involved. Based on averaged industry timelines from established eCommerce projects, typical ranges are as follows:
- Simple template-based stores usually take 4 to 8 weeks, covering discovery, light design customization, product setup, QA testing, and launch.
- Mid-sized custom stores generally take 8 to 16 weeks, allowing time for custom UI/UX design, feature development, integrations, testing, and post-launch fixes.
- Complex stores with integrations often require 4 to 6 months, as custom functionality, third-party systems, performance optimization, and extended QA increase build time.
