01 — Local economy

Business in Arlington, VA

The Pentagon sits inside Arlington, and Boeing and RTX moved their corporate headquarters to the county in 2022, so defence contractors, consultancies and federal IT integrators fill office towers in Rosslyn, Ballston and Crystal City. DARPA is also based here, and Amazon's second headquarters in National Landing has added a large corporate technology workforce.

Also known as Arlington VA and Arlington County.

Where software helps: Federal contractors here must back every billed hour with DCAA-compliant timesheets, track indirect rates and contract line items, and submit invoices through government portals such as PIEE, which basic accounting tools handle poorly.

05 — FAQ

Custom software in Arlington, VA: common questions

Do you build custom ERP and AI software for businesses in Arlington, VA?

Yes, remotely. Flip Retail is a software studio in Jaipur, India, with no office in Arlington; discovery happens on video calls and you get working software every two weeks.

How do time zones work between Arlington, VA and Jaipur?

Jaipur is 10 h 30 min ahead of Arlington, VA on standard time, and 9 h 30 min ahead during daylight saving time there. A 09:00 start there is 19:30 in Jaipur. Office hours don't overlap, so we fix one call slot at the edge of the day and work asynchronously in between.

Can a custom ERP handle Virginia sales tax?

Yes. Invoicing handles Virginia sales tax (5.3% statewide (4.3% state plus 1% local) plus regional add-ons in some areas) and the other states where you have nexus. If you or your customers want it, a custom ERP can connect to DBNAlliance through an accredited provider.

Can your AI agents talk to customers in English and Spanish?

Yes. Current language models handle English and Spanish well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.

What would a first project look like for a aerospace business?

Usually one module that fixes the most expensive problem first. For aerospace & defence supply chain that is often serial & batch traceability and certificates of conformity. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
