I need a single CRM that my internal team can open on a phone, tablet, or desktop and use as their one-stop “dealing desk.” The heart of the system is a loan calculator that instantly shows payment, APR, and total cost for terms ranging anywhere from 12 to 96 months. Around that calculator I want basic customer management: create a contact, store notes, tag leads, and pull that data straight into the calculation screen so reps never have to re-key anything. The workflow should feel seamless: a rep enters or selects a customer, tweaks loan amount and term, and the app returns payment schedules plus a quick quotation sheet they can email or download. Because only employees will sign in, authentication can stay simple but must still be secure (think role-based access, enforced strong passwords, optional SSO if it keeps effort reasonable). What I expect to receive • Installable builds for mobile (iOS & Android) and desktop or a single responsive PWA that behaves like a native app on all three form factors. • Source code, build instructions, and a small admin guide. • A tested loan engine that matches standard amortization formulas and clearly separates the APR calculation so it can be audited. • A lightweight database (cloud or on-prem) with export capability for our finance department. To be considered, send me a detailed project proposal with the TOTAL COST, outlining your chosen tech stack, milestones, timeline, and how you will validate calculation accuracy. Feel free to reference similar projects you have shipped, but a clear plan is more important than a portfolio link. Make it downloadable and ready to use
