The real problem
Is your business still running on generic tools?
Your team wastes hours in Excel
Spreadsheets that corrupt, duplicate data, and manual tasks a custom system would handle in seconds. Every lost hour is money you don't get back.
You pay for 5 SaaS that don't connect
Trello, invoicing, inventory, WhatsApp Business, email. Information scattered across 5 platforms and decisions based on incomplete data.
Your operation depends on one person
If that person gets sick or quits, everything stops. Custom software documents and automates your operation so it doesn't depend on anyone.

Real success story
B2B Portal that cut operational load for an American distributor

-62%
Less operational load

Billing errors
24/7
Orders without intervention
From processing orders by phone to an automated B2B portal
The problem
an American distributor with 200+ wholesale clients processed every order by phone and WhatsApp. They had 3 people dedicated only to taking orders, frequent errors in quantities and prices, and zero real-time inventory visibility.
The solution
We built a B2B portal where each wholesale client sees their catalog with personalized pricing, places orders directly, checks stock in real time, and downloads electronic invoices. Fully integrated with the existing accounting system.
The result
62% less operational load in the first month. The 3 people who used to take orders now focus on customer service and sales growth. Billing errors dropped to zero and orders are processed 24/7 without human intervention.

Frequently asked questions about custom software
What our clients in the USA ask before getting started
Custom software development in 2026 costs $40,000 to $400,000+ depending on complexity. Industry data aggregated across more than 5,000 projects places the average custom mobile or web build near $171,450, while Clutch reports a project average closer to $90,780. Simple internal tools run $5,000–$50,000, mid-complexity B2B apps $50,000–$120,000 and enterprise-grade platforms $100,000–$300,000. New York City hourly rates average $102/hr, with premium Manhattan boutiques charging $150–$200/hr.
Custom B2B apps in the US Northeast are typically built by boutique product studios with in-house senior engineers rather than offshore shops. In the NY/CT corridor, well-reviewed firms include Fueled, Blue Label Labs, Lickability and Appetizer Mobile in Manhattan, and NixMar Studio in Greenwich, CT for smaller mid-market budgets. Expect a four-phase engagement — discovery, design, React Native or native build, QA — running 16–28 weeks and $90K–$220K in 2026.
A functional MVP takes between 6 and 10 weeks. More complex projects like a full ERP or multi-module platforms can take 3-6 months. We work in 2-week sprints so you see real progress from the first delivery.
We offer monthly maintenance plans that include bug fixes, security updates, new features, and scaling — so your system keeps running smoothly after launch.
Yes. Data migration is part of the launch process. We move your information from Excel, Access, other software, or any existing database to the new system with zero data loss and zero downtime.
We also work on existing systems. We can add new features, modernize the interface, improve performance, or connect your current platform with other services without starting from scratch.
No. We work with businesses of all sizes in the USA and Canada — from SMEs with 10 employees to corporations with regional operations. If your operation needs more than Excel and generic SaaS, we can help.
