Why GST Billing is Still Painful for Most Small Businesses
Most shop owners still calculate GST on a separate calculator, then type the number into their billing software. One wrong digit and the invoice is wrong. Your accountant catches it at month-end. By then, you've filed incorrectly or your customer has already moved on.
GulSuite solves this at the source. When you add an item to a sale, the HSN code and tax rate are already attached to that item. GulSuite looks at your customer's state — if they're in the same state, it applies CGST + SGST. If they're in a different state, it applies IGST. You see the full tax breakdown on screen before you print. Nothing to calculate. Nothing to get wrong.
GST Features Included in Every Plan
GST billing is not an add-on in GulSuite — it's the foundation. Every plan, including the ₹399/month Starter, includes full GST-compliant invoicing:
- Tax invoices and retail invoices — full B2B and B2C format
- GSTIN on invoices — your GSTIN printed on every invoice automatically
- Customer GSTIN capture — for B2B sales and ITC claims
- HSN/SAC code per item — set once, auto-applied forever
- Tax breakdowns — CGST, SGST, IGST shown separately as required
- Credit notes — issue sales returns with correct tax reversal
- Discount handling — pre-tax and post-tax discounts handled correctly
e-Invoice and e-Way Bill (Growth, Business & Premium Plans)
If your annual turnover exceeds ₹5 crore, e-invoicing is mandatory for B2B sales. GulSuite's Growth, Business, and Premium plans include direct e-invoice generation — you get the IRN number and QR code without leaving the app. For goods movement above ₹50,000, the e-Way Bill module lets you generate the EWB number directly from your delivery challan.
Both integrations talk directly to the government portals — no third-party tools needed.
GSTR-1 Export and CA Handoff
At the end of the month, export your GSTR-1 data in the standard JSON format accepted by the GST portal. Share it directly with your CA or upload it yourself. GulSuite tracks B2B, B2C, credit notes, and exports separately — already grouped the way GSTR-1 expects them.
Your CA gets clean, structured data instead of a pile of PDFs. Filing takes minutes, not hours.
Frequently Asked Questions
Does GulSuite support all GST tax rates — 0%, 5%, 12%, 18%, 28%?
Yes. You can set any valid GST rate on each item — 0%, 5%, 12%, 18%, or 28%. Mixed-rate invoices (e.g., some items at 5% and some at 18%) are fully supported on a single invoice.
Can I issue GST invoices for both B2B and B2C customers?
Yes. For B2C customers (without GSTIN), GulSuite generates a standard retail invoice. For B2B customers (with GSTIN), it generates a full tax invoice with the customer's GSTIN, eligible for ITC claims.
Is e-invoicing (IRN + QR code) included?
e-Invoicing is available on Growth, Business, and Premium plans. If your turnover is below ₹5 crore, you don't need e-invoicing and the standard invoice format is sufficient.
Can I use GulSuite if I'm not GST registered?
Yes. If you're under the composition scheme or not registered for GST, you can turn off GST on your invoices and issue simple bills without tax breakdowns.
How do I export data for my CA at month-end?
Go to Reports → GST → GSTR-1 Export. Download the JSON file and share it with your CA, or upload it directly to the GST portal. The export is formatted exactly as required by the government portal.
