Services · Mobile app development · Online marketplace apps
Our marketplace app development in Dallas serves retailers, wholesalers and founders across North Texas who want independent vendors selling through one platform. We build the shopper and vendor apps plus the admin console, and we design them around Texas realities: the Comptroller expects marketplace providers to collect sales tax on vendor sales, the Texas Data Privacy and Security Act governs customer data, and federal INFORM rules require you to verify who your bigger sellers are.
Dallas has an unusually deep pool of merchants, from boutique owners in Bishop Arts to showroom brands that sell to the trade. A platform that serves them well has to handle both small shops shipping a few parcels and suppliers moving pallets across the metroplex, often within the same week.

What we build
North Texas commerce has two faces. One is retail: neighborhood boutiques in Bishop Arts and Lower Greenville, makers in Deep Ellum, furniture and lighting brands in the Design District. The other is wholesale: the trade-only showrooms of the Dallas Market Center, where store owners and interior designers come to buy, and the distribution warehouses that ring DFW Airport. A marketplace app for Dallas often needs to serve both.
That is why the list below mixes consumer features with trade ordering. Multi-vendor marketplace app development in Dallas also means respecting the obligations a Texas platform carries, so tax collection, seller verification and dispute evidence sit beside the shopping features rather than behind them. We help you choose which items ship first and which can wait until real vendors and shoppers show you what they use.
New vendors sign up in the app, add their business details and connect a bank account. When a vendor's sales reach the federal high-volume level, the console asks for the tax ID and contact records the INFORM Consumers Act requires, checks them, and pauses selling for vendors who ignore the request.
You know every significant seller by name, tax ID and bank account.
Since October 2019 Texas has treated marketplace providers as responsible for collecting and remitting sales tax on the sales they process for vendors. We connect a tax service that applies the state rate plus the right city, county, transit and special district rates per delivery address, and produce reports for your Comptroller filings.
A Plano delivery and a Fort Worth delivery each get the correct local rate.
Boutiques and designers who already buy wholesale can open company accounts, upload a Texas resale certificate, see trade pricing, place opening orders with minimums and reorder from past invoices. Purchase approvals and net terms are available for larger accounts.
Trade buyers keep ordering between market weeks, from their phones.
A shopper buys from three vendors in one basket and pays once. A platform payments provider divides the charge, keeps your commission and pays each vendor on the schedule you set, with refunds reversing the split automatically.
No manual transfers, and every payout matches an order.
Many Dallas vendors would rather deliver in person or offer pickup than ship a sofa through a carrier. Vendors set delivery zones by ZIP code across Dallas, Collin, Denton and Tarrant counties, choose pickup windows, and the app shows shoppers which options apply to their address.
Bulky goods sell locally without unworkable shipping quotes.
Spanish is widely spoken across Dallas County, by shoppers and by small business owners. We build listings, checkout, notifications and the vendor app with full Spanish versions, and let vendors write descriptions in either language.
More of the city can buy and sell on your platform comfortably.
Shoppers rate the vendor and the item once an order is delivered or picked up, and only verified buyers can leave a review. Vendors earn badges for fast dispatch, low return rates or local Dallas production, and your team can remove reviews that break the posted rules with a recorded reason.
Good vendors stand out and shoppers trust what they read.
Returns, missing items and damaged deliveries each open a case attached to the order. The vendor responds with photos or proof of delivery, your team decides, and the same record answers a card chargeback if one follows.
Arguments between shoppers and vendors end with a decision on file.
W-9 details are captured at signup and gross payments are tracked per vendor, so the party responsible for 1099-K filing, usually your payments provider, has clean data at the end of the tax year.
January does not start with a vendor tax data hunt.
Listing approvals, vendor scorecards, payout status, refund rates and sales by category and county, with roles for support, finance and vendor management staff.
Your team runs the marketplace from one place.
Who this suits
Online marketplace app developers in Dallas are not hard to find. What separates projects is whether the team understands your sellers and your buyers before writing code. These four starting points cover most of the Dallas businesses we talk to, and each leads to a different first release. In every case we begin with the people who will do the selling, because a marketplace without active vendors has nothing for shoppers to open the app for, however polished the screens look.
You exhibit to boutique owners and designers, and between market weeks the orders arrive by email, phone and photos of handwritten sheets. A B2B marketplace app for Dallas wholesalers can carry your line and complementary brands, with trade pricing visible only to approved accounts, minimum order rules and reorder history. Representatives can place orders on a buyer's behalf during a showroom visit, so nothing is retyped later.
Trade-only access is enforced through account approval, not a hidden page.
Your store already has loyal customers across Dallas and wants to offer goods from local makers without buying the stock. We add vendor listings, payouts and Texas tax collection to your existing app or site, keep your loyalty points working across both your products and vendor items, and give vendors a simple app to manage orders.
Loyalty rules can treat vendor items differently if your margins require it.
Western wear, vintage furniture, event rentals, sports gear: North Texas has enough buyers to test a vertical idea locally before expanding. We build a tight first version focused on trusted listings, protected payment and fast local delivery, then measure which vendors bring repeat buyers before adding more features. Keeping the first version small also keeps the budget for vendor recruitment, which is where most early marketplaces actually struggle.
Starting with one metro keeps tax registration and delivery simple.
Building materials, restaurant supplies, office goods: distributors around the metroplex sell to account holders who expect quotes, tax-exempt purchasing and invoices on terms. We build ordering, quote approval and account statements on top of your ERP so your existing inventory and pricing stay the single source of truth. Field sales staff get the same app with extra permissions, so a rep visiting a job site in Irving or Garland can quote and order on the spot.
Exemption certificates are stored and checked against each order.
How we work
Codeeo is a team of 80+ across Dubai, Riyadh and Karachi with 200+ projects delivered across the UAE and the US, rated 4.7 from 23 Google reviews. We have no Dallas office; we work remotely with Texas clients and run every workshop, review and demo by video call. Most start with a fixed scope launch build, then continue on a monthly retainer for new vendor features and support. Larger platforms sometimes take a dedicated team that works only on their product.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
Cross platform or native apps, a web storefront that ranks for local searches, and a backend whose ledger records every commission, payout and refund. Tax, payments and identity checks use proven US providers, so you can add states later without a rebuild. Admin roles and audit logs are part of the base build, not an add-on.

Shopper app, vendor app, admin console, payments, Texas tax and dispute handling.
The shopper app covers browsing, search, checkout and order tracking. The vendor app covers listings, inventory, orders, delivery and payouts. The admin console covers approvals, verification, disputes and reports. Underneath sit a platform payments provider, a sales tax service and messaging. For Dallas trade platforms we add company accounts and resale certificates; for consumer platforms we often add local delivery zones and Spanish language support. Push notifications for order updates and vendor messages come as standard.
