India GST & Tax Compliance Setup

I run a small sole-proprietorship in India and need a finance professional who can put my entire compliance stack on solid ground. My immediate priority is getting GST, income-tax, and every mandatory filing sorted out from day one so that nothing slips through the cracks later.

Here’s what I’m expecting from you:
• A clear roadmap of all registrations and returns a sole proprietor must complete, with due dates and frequency.
• Hands-on guidance (and, where possible, execution) for GST registration, monthly/quarterly GST returns, advance-tax calculations, and the annual income-tax return.
• Simple record-keeping templates or a recommended, budget-friendly software workflow that lets me stay audit-ready without hiring a full-time accountant.
• Tips on common deductions and how to structure expenses so cash flow stays healthy.
• A compliance calendar or tracker I can reuse each year.

I’m not looking for full bookkeeping or company-registration help right now—just airtight GST and income-tax compliance. If we work well together, I’m open to extending the engagement to periodic cash-flow reviews or payroll once the business scales.

Please outline how you would tackle the setup, the documents you’ll need from me, and the approximate timeline for each milestone.
