Help keep these tools free for everyone
Every tool on bydigital.in — the GST calculator, invoice generator, quotation maker, billbook and GSTIN validator — is free, unlimited, and runs privately in your browser. No accounts, no subscriptions, no locked features. If one of them saved you time or money today, you can support the work with a small donation.
Donate any amount
Payments are handled securely by Razorpay — UPI, cards, netbanking and wallets are all accepted. Even ₹20 genuinely helps.
Donate via Razorpay →You'll be taken to our official Razorpay payment page (razorpay.me/@mantukumar1708).
Where your support goes
Donations directly fund the boring-but-essential costs of running the site — domain and hosting renewals, and the development time behind new tools and updates when GST rates, late-fee caps or invoice rules change by notification. When you donate, you're effectively sponsoring the next tool and the next rule update for every user of this site.
Other ways to help (that cost nothing)
- Share a tool with a friend, your business WhatsApp group, or your CA — word of mouth is how this site grows.
- Report a bug or a wrong number via the contact page. Accuracy reports are treated as top priority.
- Suggest a tool or theme you wish existed — most features on this site started as a user suggestion.
A note on donations
Donations are voluntary contributions to support a free web project — they are not payments for goods or services, don't unlock any features (everything is already free), and are not tax-deductible. All tools remain free for everyone whether or not you donate.
