⚠ First — know your filing type
📅 Monthly Filer
Turnover > ₹5 crore OR opted monthly
File GSTR-1 every month by 11th
📆 Quarterly Filer (QRMP)
Turnover < ₹5 crore, opted quarterly
File GSTR-1 quarterly, IFF for months 1 & 2
💡 Not sure? Login to gst.gov.in → Dashboard → Check your filing frequency shown there.
📅 MONTHLY FILER — Filing GSTR-1
Easiest method: Use JSON offline upload — uploads everything in one file
1
Login → gst.gov.in → Services → Returns → Returns Dashboard
2
Select Financial Year and Tax Period (month)
3
Click GSTR-1 → Click Prepare Offline tab (NOT Prepare Online)
4

Portal uploads B2B invoices + HSN Summary + Table 13 all at once → click Generate Summary
6

⚠ Do NOT click "Prepare Online" for uploading. Prepare Online only allows manual entry one-by-one. Always use Prepare Offline → Upload for bulk invoices.
📆 QUARTERLY FILER (QRMP) — Filing GSTR-1
In QRMP scheme: Month 1 & Month 2 of quarter → use IFF (only B2B invoices). Month 3 → file full GSTR-1.

Returns Dashboard → IFF → Prepare Online → 4A,4B,6B,6C → Add invoices (B2B only)
Month 3 — Full GSTR-1
Returns Dashboard → GSTR-1 →
Prepare Offline → Upload our JSON file
💡 IFF does not support JSON/CSV upload — you must enter B2B invoices manually or one-by-one in Month 1 & 2. Only Month 3 supports bulk upload.
📊 GSTR-3B — Same steps for Monthly & Quarterly

Returns Dashboard → GSTR-3B → Prepare Online

8 Already Using Tally? Use CSV Upload
If you maintain invoices in Tally or Excel, use the CSV Upload feature instead of creating invoices in the app.
1
In Tally: Gateway → Display → GST Reports → GSTR-1 → Export CSV
2
In GSTKaro: tap 📂 Upload in bottom menu
3
Select your state, GSTIN and GST rate → upload the CSV file
4
Review the data → go through tabs: GSTR-1 | HSN | GSTR-3B
5
Download all CSVs → upload to GST portal
💡 HSN Summary is under the HSN tab in Step 3 of the upload flow. Required if annual turnover > ₹5 crore.
9 Online Business / Razorpay Users
If you collect payments online via Razorpay and your price includes GST, use the Razorpay Processor.
1
Download payment export from Razorpay Dashboard → Reports → Payments → Export CSV
2
Open 💳 Razorpay tab in GSTKaro
3
Set your state, GST rate, and whether price is GST inclusive or exclusive
4
Enter Razorpay gateway charges + GST from your monthly Razorpay Tax Invoice
5
Upload the CSV → app auto-calculates CGST/IGST per payment based on customer state
6
Download GSTR-1 + HSN + GSTR-3B → file on portal
💡 Razorpay is in Karnataka — so gateway charges are always IGST. You can claim this as ITC in GSTR-3B Section 4.
10 Common Questions
My data shows on phone but not on laptop?
Login with the same email on laptop. All data syncs automatically from the cloud — same data on all devices.
I cleared browser data — are my invoices lost?
No. All invoices are saved in our secure cloud database. Just login again and everything loads automatically.
CGST or IGST — how does it decide?
If customer's state = your state → CGST + SGST. If different state → IGST. App detects automatically from customer's GSTIN. Just enter the GSTIN correctly.
Invoice showing in app but not in GSTR-1?
Check the month and year selected in GSTR-1 matches the invoice date. Also make sure you click the Load button after selecting the month.
What is ITC and how do I claim it?
ITC = Input Tax Credit. GST you paid on business purchases (hosting, software, office supplies, Razorpay gateway etc.). Enter the amount in the ITC field in GSTR-3B. It reduces your net GST payable. You need a valid Tax Invoice from the supplier with your GSTIN.
I reached 10 invoice limit on Free plan?
Upgrade to Pro (₹299/month) for unlimited invoices. Contact support@dhenuja.com to upgrade.
Can I have multiple GSTINs?
Currently one GSTIN per account. For multiple GSTINs, contact us for Agency plan.
11 Export to Tally (New)

12 Export Invoices for Foreign Clients (New)
For IT services, software, or any supply to foreign clients — use Export invoice type.
1
New Invoice → Invoice Type → select Export — Without GST Payment (most IT exporters use this — need active LUT)
2
A blue 🌍 Export Details panel appears → fill Country, Currency (USD/EUR etc.)
3
Shipping Bill Number and Port Code are optional for services — leave blank if you're a service exporter
4
Enter your LUT/Bond Number (Letter of Undertaking filed with GST dept)
5
Save invoice → goes into Table 6A (Exports) in GSTR-1 automatically
⚠ Without Payment of GST requires an active LUT. File LUT every April on the GST portal — it's free. Without LUT, you must pay IGST and claim refund later.
