I need a secure, browser-based accounting platform designed for professional accountants. The system must live entirely in the cloud, offer multi-company ledger management, intuitive journal entry screens, adjustable reporting periods, drill-down financial statements, and a full audit trail. Seamless, automated integrations with major Banking systems are critical so statements can be pulled in real time and reconciled quickly. Likewise, the platform must connect to common Payroll systems, posting payroll journals without CSV uploads or manual data entry. I’m happy with any modern web stack—Laravel, Django, Node.js, or similar—so long as it is container-friendly and can be deployed on AWS, Azure, or Google Cloud. Role-based access, two-factor authentication, and encryption at rest and in transit are mandatory. A clean, mobile-responsive interface and the ability to export reports in PDF and CSV round out the essentials. Deliverables • Cloud-hosted application accessible via HTTPS • Working Banking and Payroll integrations with REST API documentation • Source code in a private Git repository, plus clear deployment instructions • Concise user guide tailored for accountants Acceptance criteria: the application must sync bank feeds and payroll data error-free, maintain sub-two-second page loads for datasets up to 50,000 transactions, and generate balance sheet, P&L, and cash-flow reports that reconcile perfectly with imported data. Outline your timeline and milestones in your proposal so I can align our schedules.
