Every invoice app can tell you who owes you money. This one picks up the phone and asks for it. Invoice Manager Pro now comes with an AI receptionist. It answers the calls you miss while you are on a job, books the work, and when an invoice goes past due it calls the customer, politely, in your name, only when you say go, then tells you exactly what they said. Still no monthly fee. Still works offline. Still yours on every device. YOUR AI RECEPTIONIST • Chases late invoices by phone. It knows who owes what and for how long, because it is reading your ledger, not guessing. You approve who gets called and when. • Answers the calls you cannot take. Missed calls are missed jobs. It picks up, answers questions about your services and hours, and takes a message you can read later. • Books the job. New enquiries go straight into your calendar with the customer's details already filled in. • Identifies itself as an AI, on a recorded line, every time. You get a full transcript, a summary and the outcome of every call. • You set the tone. Firm with the customer who is 90 days late, gentle with the one who has always paid. THE REST OF THE BUSINESS, STILL INCLUDED • Invoices, estimates and quotes, send one in under a minute • Receipt scanner, snap it and it files itself • Mileage tracker, GPS logs every trip for you • Time tracking, bill what you actually worked • Accounting and tax tools for 15 countries • Team, payroll and schedules • Inventory and point of sale • Projects, reports and analytics • Chat or talk to your AI assistant about any of it GET PAID YOUR WAY Stripe, Square, Apple Pay, PayPal, Venmo, Zelle and bank transfer, straight from the invoice.
