Raise the invoice. The return writes itself.
Every invoice you raise in KyDec gets its IRN, posts its own ledger entry and lands in GSTR-1 — then purchases match against GSTR-2B and GSTR-3B adds up. You or your CA review and file. No Excel in between.
Basic is free — no card needed. Human support on every plan.
The 11th, the 13th, the 20th. Handled.
GST runs on dates. KyDec keeps the numbers for each return assembled as you work, so the due date is a review, not a scramble.
Merit & essentials. The lower slab.
Standard. Most goods and services.
Luxury & sin goods. The new top slab.
Rates set per line, per HSN/SAC — KyDec splits CGST + SGST/UTGST or IGST from the place of supply.
Type a GSTIN: KyDec checks its format and check digit, and reads the state and PAN from it.
Eight things a GST invoice must show. KyDec prints all eight.
- Supplier name, address and GSTIN
- Unique serial number (max 16 characters, per FY) and date
- Recipient name, address and GSTIN, if registered
- Place of supply (state) for inter-state supplies
- HSN/SAC code, description and quantity
- Taxable value, GST rate and CGST/SGST/IGST amounts
- IRN and signed QR code, where e-invoicing applies
- Signature or digital signature of the supplier

IRN at the moment you invoice. Not on day 29.
KyDec generates the IRN and signed QR from the invoice itself, once the business's e-invoice API access is set up.
Turnover above this in any FY since 2017-18 puts B2B invoices, notes and exports under e-invoicing.
Some sectors exempt, e.g. banks, insurers, GTA, SEZ unitsSince 1 April 2025, AATO ≥ ₹10 crore must report to the IRP within 30 days of the invoice date, or it is rejected.
No further threshold cut notified, Oct 2026Above this, B2C invoices need a dynamic QR code.

Does KyDec file my GST returns?
KyDec prepares GSTR-1, 2B reconciliation, 3B, GSTR-4, 9/9C, CMP-08 and IFF. You or your CA review and file on the GST Portal. IRNs are generated from KyDec directly; e-way bills are not built yet.
We're under ₹5 crore. Do we need e-invoicing?
Not until aggregate turnover crosses ₹5 crore in any FY since 2017-18. Until then KyDec prints normal GST invoices with every required field.
What is the 30-day IRN rule?
Since 1 April 2025, AATO ≥ ₹10 crore must report invoices to the IRP within 30 days or they are rejected. KyDec raises the IRN with the invoice.
Are the GST 2.0 rates in?
Yes. Rates are per line, so the 5%, 18% and 40% slabs from 22 September 2025 and special rates like 3% on gold just work.
Can we move from Tally mid-year?
Yes. Data in week one, formats set up, an hour of training, and we sit through your first month-end.
Payroll, PF and ESI?
Not yet — Payroll & HRMS is coming soon. Salary and statutory payments can be recorded in the books today.
