Give clients the access model that fits the moment: a lightweight review link for a single post or a portal for ongoing workspace access. Both stay inside a bounded feedback and revision process.
Yes, when your priority is INR billing, GST invoicing, UPI payments and a workflow built around multi-client content feedback. Nudge may be the better fit when whatsapp-native approvals and follow-up for indian agencies is your primary requirement.
Poststack uses flat INR plans by account band: ₹2,000 for 3 accounts, ₹4,400 for 10 accounts, or ₹8,000 for 30 accounts, with explicit add-ons for extra accounts and team members. Nudge uses founding-agency onboarding with a free client allowance. Its current public pricing snapshot is free for the first 3 clients; current public page says founding agencies are being onboarded and does not publish paid tiers, with the restrictions listed in the comparison above.
Poststack supports two client workflows: a no-login magic link for quick post review and an authenticated client portal for ongoing workspace access. It also caps revision rounds and is billed in INR, while Nudge one-tap approval or revision request inside whatsapp.
Poststack publishes to Instagram, Facebook, LinkedIn, X, YouTube and Threads. Compare that list with the networks your team actively manages, since broader coverage only matters when you use those channels.
Use a magic link when a client needs to review a specific post without creating an account. Use the authenticated client portal when a client needs an ongoing view of their workspace calendar and feedback history. Both workflows feed into the same revision record for the operator.
Yes. The magic-link workflow lets a client view a specific post and leave feedback without creating a Poststack account. Clients who need ongoing workspace access can use the authenticated client portal instead.
