Small business in Maryland
Maryland's small businesses split between the Baltimore area, with its rowhouse contractors, restaurants and medical offices, and the Washington suburbs in Montgomery and Prince George's counties, where professional firms and government contractors are common. Annapolis has marine and tourism businesses, and the Eastern Shore relies on seafood, farming and summer visitors in Ocean City.
According to the SBA Office of Advocacy's 2025 profile of Maryland, the sectors with the most small employers are professional services such as law, accounting, engineering and consulting, construction and the trades, repair and personal services such as auto repair, salons and dry cleaners, health care, including medical, dental and therapy offices and retail shops.
Where Ava helps Maryland businesses
- Annapolis marine and charter businesses. Boatyards, sailing schools and charters on the Severn and the Bay can let Ava take slip, haul-out and charter requests while staff are on the docks.
- Government contractors and consultants. Small firms near Fort Meade, Bethesda and Columbia can have Ava screen inquiries and book callbacks during meetings.
- Rowhouse repairs. Baltimore plumbers, roofers and handymen can have Ava capture the address and problem while they're on a job.

Recording calls in Maryland
All-party consent. Maryland is an all-party consent state. Courts and Judicial Proceedings § 10-402 prohibits intercepting wire, oral or electronic communications, with an exception only when the person is a party and all parties have given prior consent. If you record calls with Maryland customers, tell callers at the start.
Maryland businesses often get calls from Virginia, Pennsylvania, Delaware and West Virginia. Of those, Pennsylvania and Delaware require all-party consent or have unsettled rules, which is one more reason to give a notice at the start.
Ava always says she's an AI. If your setup records calls, the script we draft adds a short recording notice to her greeting, and you approve the wording. Interstate calls can be tricky; see the state-by-state overview.
Time zones and after-hours coverage
Maryland runs on Eastern Time. We set Ava's business-hours and after-hours scripts to your local Maryland time, so early-morning and late-night callers still reach someone.
