Poststack gives every client its own calendar, a no-login approval link and publishing via official APIs, priced in rupees with GST invoices
Poststack
The social media scheduler built around how Indian agencies actually work
Picture a four-person agency carrying twenty client accounts. One client sends the new logo on WhatsApp, another asks whether v3 or v7 is final, a third wants to know if yesterday's reel went out. Poststack was built for that exact afternoon. Its founder started from how Indian agencies really operate, then designed the product around the handoffs where the hours quietly disappear.
Every client gets a dedicated workspace with its own calendar, connected accounts, settings and feedback history. The latest version of a post and the comments that shaped it stay together, so nobody has to scroll a chat to find out what is final.
Where it shines
Client approval is the star. You send a single link, the client opens the post without creating an account, and their feedback lands on the post itself. You set how many revision rounds each client gets, every round is counted and recorded, and your team keeps control of marking work final, scheduling and publishing. Higher plans add a full client portal, with a white-label version on your own domain available on request.
Around that sit the agency essentials: one calendar across every client, team roles with per-action permissions, a spreadsheet import for planned posts, Google Drive media, and analytics for all six platforms.
Who will love it
Indian social media agencies and freelancers who have outgrown global tools priced in dollars and supported from another timezone. Paying in rupees by UPI with automatic GST invoices, scheduling natively in IST and getting support during Indian working hours all add up. The best way to start is the interactive demo, which opens a full sample agency workspace in your browser with no account needed.
Finally, a scheduler that understands the 11pm founder feedback message and the GST invoice.
