There’s no single “best” SIP platform for everyone — it depends on what you value (lowest cost, best research, ease of switching to direct plans, integrated broking, customer support). Quick shortlist of top choices in India (strength + one-line why), and what to check when you pick:

Top platforms (summary)

• Zerodha Coin — excellent if you already use Zerodha/Kite; Coin offers direct mutual‑fund plans, daily SIPs, STP and UPI‑autopay options and high mandate limits. (zerodha.com)
• Kuvera — focused on direct plans, goal planning, portfolio import and switching regular→direct; good if you want a free, goal-driven direct‑MF experience. (forbes.com)
• Groww — very user‑friendly app, strong fund discovery and research tools and a large user base (easy for beginners). (groww.in)
• ET Money — zero‑commission direct funds plus strong tracking/tools (Genius) and easy SIP setup; good for disciplined automated investing. (etmoney.com)
• Upstox — low‑cost option with SIP features (step‑up/modify), useful if you want broking + MF under one account (note: some MF features require a Demat/account setup). (upstox.com)
• Paytm Money — direct plans, daily SIP and “all‑in‑one” SIP features; good for minimal cost and very small daily SIPs. (paytmmoney.com)

Which platform to pick based on priorities

• Lowest ongoing cost (maximize returns): Kuvera, Zerodha Coin, ET Money, Paytm Money (direct plan platforms). (forbes.com)
• Best UI/research for beginners: Groww, ET Money. (groww.in)
• If you already trade equities and want everything in one place: Zerodha (Coin) or Upstox. (zerodha.com)
• Want to switch regular plans to direct plans / consolidate holdings: Kuvera supports easy portfolio import and switching. (kuvera.freshdesk.com)

Quick checklist before you open/start a SIP

• Are you buying direct plans (lower expense ratio) or regular plans? (Prefer direct for long‑term SIPs.) (etmoney.com)
• SIP features you need: daily SIP, step‑up, ability to modify/stop, UPI Autopay/mandate. (Different apps support different features.) (zerodha.com)
• Any Demat requirement (some platforms require/wrap MFs via Demat). (upstox.com)
• Customer support / dispute resolution and AMC coverage (all major AMCs available on leading platforms).
• Check fund expense ratio, exit load and historic performance of the fund (not the platform).

If you want one short recommendation

• If cost and switching to direct plans matter most: start with Kuvera or Zerodha Coin. Kuvera is especially strong for goal‑planning and switching/import; Zerodha Coin is great if you already use Zerodha for stocks. (forbes.com)

If you’d like, I can:

• compare 2–3 platforms you’re considering (fees, SIP features, daily SIP, UPI‑autopay, demat requirement), or
• show how to move a regular plan to a direct plan (steps for Kuvera/Zerodha).

Which one should I compare for you?
