For most of our clients that's a client portal, a CRM, a booking system or an internal dashboard that replaces a pile of spreadsheets and disconnected apps. - [Mobile Apps](https://virtualhorizons.pro/services/mobile): A mobile app development company designs, builds and publishes apps for iPhone and Android, then keeps them working as the operating systems change. The part most teams underestimate is the last mile: store listings, screenshots, privacy forms and getting through Apple's and Google's review. - [Marketing Video](https://virtualhorizons.pro/services/video): AI marketing video uses generative video, image and voice tools to produce ads, product launches and social content much faster than a traditional shoot. A human still writes the script, directs the look and edits the final cut, which is what keeps it on brand. - [CRM & Automation](https://virtualhorizons.pro/services/automation): CRM automation is setting up your CRM so routine follow-up happens on its own: new leads get a text in seconds, appointments trigger reminders, and deals move stages without someone copying data by hand. Integrations connect the CRM to the rest of your tools so the data stays in one place. - [Voice AI](https://virtualhorizons.pro/services/voice): An AI voice agent is software that answers and makes phone calls in a natural voice, understands what the caller wants and takes action, like booking an appointment or updating your CRM. Used for inbound calls, it works as an AI receptionist that never misses a call. - [Conversational AI](https://virtualhorizons.pro/services/conversational): Conversational AI is software that holds a real back-and-forth conversation in text or voice, understands the question and responds with a useful answer or action. For a business that usually means a website chatbot or SMS assistant that answers questions, qualifies leads and books appointments. ## Specialties - [Base44 Developers & Agency, Legend Partner](https://virtualhorizons.pro/base44-developers): Base44 gets you to a working prototype fast, but turning it into a product people pay for takes engineering judgment: data models that scale, security rules that protect customer data, integrations that don't break, and a clean path to the app stores. A Base44 developer handles that part so you can keep moving. - [AI Receptionist for Small Business, Built for You](https://virtualhorizons.pro/ai-receptionist): An AI receptionist is a voice agent that answers your business phone like a trained front desk: it greets callers, answers common questions, books or reschedules appointments and passes anything complex to a person. Unlike voicemail, it actually resolves the call. - [AI Answering Service for Small Business, 24/7](https://virtualhorizons.pro/ai-answering-service): An AI answering service is a voice agent that covers your phone when nobody else can: after hours, during lunch, on weekends or when every line is busy. Instead of only taking a message, it can answer common questions, book appointments, screen for emergencies and send your team a written summary of every call. - [AI Consulting for Small & Mid-Size Businesses](https://virtualhorizons.pro/ai-consulting): An AI consultant figures out where AI can save time or bring in revenue for your business, which tools fit, and what it will take to get there. The useful ones also build and launch it, measure the result and train your team, so the plan does not die after the kickoff meeting. - [AI Automation Agency for Small & Growing Businesses](https://virtualhorizons.pro/ai-automation-agency): An AI automation agency finds the repetitive work in your business, like answering calls, chasing leads, booking appointments and copying data between tools, and builds AI and automation that handle it reliably. The good ones start with one workflow that pays for itself, measure it, then expand. - [App Developer in Hawaii: Web, Mobile & AI, Honolulu](https://virtualhorizons.pro/hawaii-app-developer): Time zones and context. Hawaii doesn't observe daylight saving time, so mainland agencies are two to six hours ahead and your best hours rarely overlap. A local studio meets when you're working, understands visitor-heavy and seasonal businesses, and builds for customers calling from every time zone. ## AI receptionist by industry - [AI Receptionist for Accounting Firms](https://virtualhorizons.pro/ai-receptionist/accounting-firms): It answers your line all year, and especially during tax season. It sorts new prospects from existing clients, books consultations and appointments, answers questions about your services, hours and document checklist, and takes detailed messages about return status or billing. It never gives tax or accounting advice and never collects Social Security or bank numbers by phone. - [AI Receptionist for Auto Repair Shops](https://virtualhorizons.pro/ai-receptionist/auto-repair): It answers the shop phone like an experienced front counter person. It books oil changes, inspections, brake work and diagnostics with the year, make, model and mileage captured, answers 'is my car ready' calls, gives the price ranges you approve for common services, and routes estimate approvals and anything technical to your advisor with a clear summary. - [AI Receptionist for Car Dealerships](https://virtualhorizons.pro/ai-receptionist/car-dealerships): It answers your main line and service line, figures out whether the caller needs sales, service, parts or finance, and handles what it can on the spot. It books service appointments, answers basic questions like hours and directions, and passes sales leads to your BDC or a salesperson with notes. It never quotes prices, payments, rates or trade values. - [AI Receptionist for Chiropractors](https://virtualhorizons.pro/ai-receptionist/chiropractors): It answers your office line, books new patient exams into the longer slots you set, reschedules and cancels existing visits, answers questions about insurance, cash pricing and what to expect at the first visit, and captures personal injury intake details if you take those cases. Clinical questions go to the doctor, never to the AI. - [AI Receptionist for Cleaning Services](https://virtualhorizons.pro/ai-receptionist/cleaning-services): It answers every call, asks about the home or building the way your office would (size, bedrooms, bathrooms, pets and the kind of clean), and either gives a quote range using your rules or books a walkthrough. It sets up recurring cleans, handles reschedules and skips, and sends complaints or special requests to a manager. - [AI Receptionist for Dental Offices](https://virtualhorizons.pro/ai-receptionist/dentists): It answers every call in your practice's name, books and reschedules appointments, answers common questions about insurance, hours and services, and follows your rules for dental emergencies. Anything it shouldn't handle, like a billing dispute or a clinical question, goes to the right person with a clear summary. - [AI Receptionist for Electricians](https://virtualhorizons.pro/ai-receptionist/electricians): It answers your line 24/7, screens every call for real hazards, and tells callers with sparking, smoke or a burning smell to get safe and call 911 or their utility before anything else. Routine work like outlets, lighting, panel upgrades and EV chargers gets booked on your calendar, and true emergencies go straight to your on-call electrician. - [AI Receptionist for General Contractors](https://virtualhorizons.pro/ai-receptionist/general-contractors): It answers your business line around the clock, finds out what kind of project the caller has in mind, checks the address against your service area and books an estimate visit on your calendar. It takes detailed messages for existing clients, subs and suppliers, and texts you right away when a big or urgent job comes in. - [AI Receptionist for Hotels and Rentals](https://virtualhorizons.pro/ai-receptionist/hotels): It answers reservation and guest calls 24/7. It checks availability and books through your property management system or booking engine where that is connected, or texts the caller a secure booking link. It answers questions about parking, check in, amenities and directions, logs guest requests for housekeeping or maintenance, and sends anything urgent to the manager on duty. - [AI Receptionist for HVAC Companies](https://virtualhorizons.pro/ai-receptionist/hvac): It answers every call around the clock, books repair, maintenance and estimate visits within your service area, and follows your rules for after-hours emergencies. It also captures system details up front so your techs arrive knowing what they are walking into. - [AI Receptionist for Insurance Agencies](https://virtualhorizons.pro/ai-receptionist/insurance-agencies): It answers your agency line, works out whether the caller needs a quote, has a claim, or needs policy service, and handles each one within your rules. Quote requests are captured with drivers, vehicles or property details and current carrier, then booked with a licensed agent. Claims callers get the right carrier claims number and their account manager is alerted. It never binds coverage or gives coverage advice. - [AI Receptionist for Landscaping Companies](https://virtualhorizons.pro/ai-receptionist/landscaping): It answers every call, checks the property address against your service area, and sorts the caller into recurring maintenance, a one time cleanup, an install or design estimate, irrigation work or a commercial bid. It books what it can, explains your plans in your words, and sends larger jobs to your estimator with the details already collected. - [AI Receptionist for Law Firms](https://virtualhorizons.pro/ai-receptionist/law-firms): It answers every call in your firm's name, gathers intake details by practice area, collects names for a conflict check and books consultations on the right attorney's calendar.

It does not give medical advice, and it routes post-treatment concerns to your clinical team right away. - [AI Receptionist for Medical Offices](https://virtualhorizons.pro/ai-receptionist/medical-offices): It answers every call, schedules and reschedules visits by type and provider, takes refill and referral requests in a structured way, and answers routine questions about hours, location and accepted insurance. It never gives medical advice, and it routes urgent symptoms by the rules your clinical team writes. - [AI Receptionist for Pest Control Companies](https://virtualhorizons.pro/ai-receptionist/pest-control): It answers every call, asks what the caller is seeing and where, and books the right service: a one time treatment, an inspection, or a spot on your recurring plan. It handles reschedules and re-treat requests, takes commercial inquiries, and sends anything urgent or unusual to your office with a clear summary. - [AI Receptionist for Plumbers](https://virtualhorizons.pro/ai-receptionist/plumbers): It answers every call day and night, books drain, leak, water heater and fixture jobs inside your service area, and follows your rules for after-hours emergencies. While a caller waits, it can explain how to shut off their water using steps you approve. - [AI Receptionist for Property Management](https://virtualhorizons.pro/ai-receptionist/property-management): It answers your office and after-hours lines and works out whether the caller is a resident, prospect, owner or vendor. Maintenance requests are captured with unit, issue and access details. Emergencies like flooding, a gas smell or no heat in winter go to your on-call person right away. Prospects get availability and a tour booking, and rent or lease questions are answered from your policies. - [AI Receptionist for Real Estate Agents](https://virtualhorizons.pro/ai-receptionist/real-estate): It answers your business line or listing lines like a trained inside sales assistant.

It books, changes and cancels reservations, answers questions about hours, parking, the menu and private dining, texts a link for takeout or delivery, and passes catering leads, complaints and anything unusual to a manager. Calls get answered on a Friday night instead of ringing out. - [AI Receptionist for Roofing Companies](https://virtualhorizons.pro/ai-receptionist/roofers): It answers every call, books inspections and replacement estimates, takes leak calls and follows your rules for urgent ones, and collects details like roof age, damage and whether an insurance claim is open. It keeps up with storm surges, and it never makes promises about what insurance will cover. - [AI Receptionist for Salons and Barbershops](https://virtualhorizons.pro/ai-receptionist/salons-and-barbershops): It answers every call, books services with the right stylist or barber for the right amount of time, handles reschedules under your cancellation policy and answers questions about prices, hours and wait times. Your team keeps working on the client in the chair instead of running to the front desk. - [AI Receptionist for Veterinary Clinics](https://virtualhorizons.pro/ai-receptionist/veterinary): It answers the clinic line, books wellness, vaccine and sick visits using your appointment types, captures prescription refill and records requests for your team to approve, answers routine questions about hours and services, and follows your emergency protocol the moment a caller describes something urgent.
