Sign in with Google above, pick a plan, and pay in the Razorpay window. You land back on your account page, which waits for the subscription to activate and then shows your new plan.

One thing actually changes: how many products you can sell.
We'd rather say it plainly than pad a table. Here's every row, including the ones that are identical across all three plans.

Paying
Two doors, one account.
Whether you subscribe here or inside the app, the payment is tied to the same Google identity — so your plan is waiting for you on whichever device you open next.
From inside the app
Settings → Upgrade opens a secure, single-use checkout link in your browser, valid for 15 minutes. Same plans, same Razorpay window, same account gets upgraded.
Billing questions
Before you pay.
Which payment methods work?
Everything Razorpay supports for recurring payments in India — UPI mandates (GPay, PhonePe, Paytm, BHIM), credit and debit cards, net banking and wallets. The payment form is Razorpay's own; your card number never touches 3DCalci.
What actually happens when I hit the product limit?
Adding a new catalog product is refused with a clear message naming your plan and its limit. Nothing you already created is deleted.
If you downgrade or let a plan lapse with more products than the lower tier allows, your products are kept but your public catalog shows only the oldest ones up to that tier's cap. Upgrade again and the rest reappear.
How do I cancel?
From your account page here, or from Account inside the app. Cancellation takes effect at the end of the period you've already paid for — you keep your plan until then, and you are not charged again.
Is the annual plan really cheaper?
Yes — the per-month rate drops and you are charged once for the year. The exact saving is shown on the toggle above and is calculated from the live prices, not a fixed marketing number.
Do I need a GSTIN to subscribe?
No. A GSTIN is only needed if you want your own GST number printed on the invoices you issue to your customers — you set that once in your business profile.
I paid but my plan still says Free.
Activation is confirmed by Razorpay calling our server, which usually takes a few seconds. Your account page polls for it automatically. If it hasn't flipped after a minute, reopen the account page — and if it still hasn't, email hello@wynstack.com with the Razorpay payment id.
Start on Free. Move up when it pays for itself.
Pro costs less than a single mis-priced print. Sign in and see where you land.
