Software Development for Businesses in the USA
US companies usually come to us for one of two reasons: a local agency quoted more than the project was worth, or a freelancer went quiet halfway through. What we offer instead is a team that stays accountable, a fixed quote, and a time difference that works in your favour.
Short answer
A2Z Global builds websites, custom software, ecommerce stores and mobile apps for US businesses as an offshore development team based in Karachi, Pakistan. We overlap with US mornings for calls and build overnight, integrate Stripe, QuickBooks and shipping carriers, and build to WCAG accessibility standards. Every project gets a fixed written quote.

What software for the USA has to handle
Tax, invoicing, payments, language and data rules all change from one market to the next. These are the ones we design for here.
| Area | In the USA |
|---|---|
| Tax | Sales tax is set by each state, and many local jurisdictions add their own, so online sellers usually calculate it through a service such as Avalara or TaxJar rather than hard-coding rates. |
| E-invoicing | There is no federal e-invoicing mandate for private businesses in the US. Invoicing is driven by your accounting system and your customers' requirements. |
| Data and privacy | There is no single federal privacy law. State laws apply — California's CCPA/CPRA is the best known — alongside sector rules such as HIPAA for health data. Website accessibility is also a real legal exposure: businesses are sued under the ADA over inaccessible sites, so we build to WCAG. |
| Language | English. Spanish interfaces where your customers need them. |
| Payments | Stripe, PayPal, Square, Authorize.net, Apple Pay and Google Pay, Affirm and Klarna |
| Couriers | USPS, UPS, FedEx, ShipStation |
| Accounting software | QuickBooks, Xero, NetSuite |
| Marketplaces | Amazon, Walmart Marketplace, Etsy, eBay |
| Working hours | Pakistan is 9 to 10 hours ahead of US Eastern time, so we overlap with your morning for calls and build while you sleep — you wake up to progress rather than waiting on it. |
| Pricing | Priced per project. You get one fixed written quote after a discovery call. |

/FAQ
Working with A2Z Global from USA
How do you handle the time difference?
We overlap with your morning for calls and demos, then build during your night. Most US clients find they wake up to progress. Anything urgent reaches us on WhatsApp or Slack.
Do you build ADA-accessible websites?
We build to WCAG guidelines — keyboard navigation, contrast, labels, alt text and screen-reader structure — because inaccessible sites are a real source of ADA lawsuits in the US. Full legal compliance is a matter for your counsel, but the build is done properly.
Can you integrate with Stripe and QuickBooks?
Yes. Stripe, PayPal and Square for payments, QuickBooks, Xero or NetSuite for accounting, and sales tax through Avalara or TaxJar where you sell across states.
Who owns the code and accounts?
You do. The repository, hosting, domain and app store accounts are set up in your company's name, and the code is handed over in full.
