Rules your software must follow in the United States

Tax, e-invoicing, data-protection and AI rules that shape an ERP, billing system or AI agent in the United States. Last reviewed October 2026.

Indirect taxSales and use tax (state and local) · No federal VAT; state rates 0-7.25%There is no national VAT or GST; 45 states plus DC levy sales tax, usually with local add-ons, and since the 2018 Wayfair decision remote sellers must collect once they pass each state's economic-nexus threshold, while taxability of SaaS and digital goods varies by state.
E-invoicingVoluntary · DBNAlliance (voluntary Peppol-style exchange network)There is no federal or state B2B e-invoicing or real-time reporting mandate; adoption is voluntary, with the industry-led DBNAlliance network (live since 2024) providing a Peppol-like four-corner standard.
Data protectionNo comprehensive federal privacy law (state consumer privacy laws plus sectoral federal laws such as HIPAA, GLBA, COPPA and the FTC Act)Nineteen state comprehensive privacy laws were in effect by January 2026, with Oklahoma, Louisiana, Alabama and Vermont laws enacted in 2026 taking effect in 2027-2028; they generally require privacy notices, opt-outs from sale, targeted advertising and profiling, consent for sensitive data in many states, and processor contracts, and every state has a breach-notification law.
AI rulesNo federal AI statute; Executive Order 14365 (Dec 2025) directs the Justice Department to challenge state AI laws, but state rules still apply, such as Utah's AI disclosure law, Texas TRAIGA and California's companion-chatbot (SB 243) and frontier-model (SB 53) laws from Jan 2026, and Colorado's rewritten automated-decision law from 1 Jan 2027.
Systems we migrate from or connect toQuickBooks, Xero, NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central, FreshBooks, OdooMasters, ledgers, stock and open balances move across and are reconciled before cutover.
Payment rails for web apps and SaaSACH, Stripe, Square, PayPal, Authorize.net, RTP and FedNow instant payments
Also worth knowingBilling systems need jurisdiction-level sales tax calculation and exemption-certificate handling, and several states have recently extended tax to software and IT services, e.g. Maryland's 3% tax on IT and software publishing services from July 2025 and Washington's tax on certain IT services from October 2025.

05 — FAQ

Custom software in the United States: common questions

Do you work with businesses in the United States?

Yes. Flip Retail is based in Jaipur, India, and works with United States businesses remotely. We have no office in the United States; discovery happens on video calls, you get working software every two weeks, and the engineers who write the code are on the calls.

Can a custom ERP handle sales tax and e-invoicing in the United States?

Yes. Invoicing handles state and local sales tax for every state where you have nexus, with rates and taxability rules kept current. There is no federal or state B2B e-invoicing or real-time reporting mandate; adoption is voluntary, with the industry-led DBNAlliance network (live since 2024) providing a Peppol-like four-corner standard. If you or your customers want it, a custom ERP can connect to DBNAlliance through an accredited provider.

How do you handle state privacy laws?

Nineteen state comprehensive privacy laws were in effect by January 2026, with Oklahoma, Louisiana, Alabama and Vermont laws enacted in 2026 taking effect in 2027-2028; they generally require privacy notices, opt-outs from sale, targeted advertising and profiling, consent for sensitive data in many states, and processor contracts, and every state has a breach-notification law. You choose where the system is hosted, access is role-based, and we work on test or masked data during development wherever possible.

Can you migrate us from QuickBooks, Xero or NetSuite?

Yes. Masters, ledgers, stock items and opening balances move across and are reconciled with your accountant before cutover, ideally at a year-end or quarter-end.

Are there AI rules we need to follow in the United States?

No federal AI statute; Executive Order 14365 (Dec 2025) directs the Justice Department to challenge state AI laws, but state rules still apply, such as Utah's AI disclosure law, Texas TRAIGA and California's companion-chatbot (SB 243) and frontier-model (SB 53) laws from Jan 2026, and Colorado's rewritten automated-decision law from 1 Jan 2027. We design AI agents with logging, human oversight and clear disclosure from the start, which covers most current requirements.
