Less headache
GST on every bill. Calm when the CA calls.
Month-end GST prep from the same invoices you print — no last-minute rebuild.
Simple Bills calculates CGST, SGST, or IGST from your company and customer state. Then download a GST filing pack — portal-ready GSTR-1 CSVs for the government Offline Tool, plus CA review copies and GSTR-3B-style totals — all from the same invoices you raised all month.
The daily headache we fix
Wrong tax split on invoices, HSN missing on lines, and scrambling for GSTR-friendly numbers three days before the deadline.
HSN & rates on products
Tax rates live on product master — staff picks items, tax follows.

GST filing pack (for your CA)
GSTR-1 portal CSVs — B2CS, B2CL, B2B, CDNR, CDNUR, HSN — formatted for the GST Offline Tool, plus readable copies for your CA.
Export when filing time comes
Download from Reports — from books that match your sales and returns. You file on gst.gov.in; Simple Bills prepares the numbers.
GST filing pack — what you actually download
Built for monthly GSTR-1 and GSTR-3B filers. Two kinds of CSV: for the GST portal (upload in Offline Tool) and your copy (readable sheets for your CA).
GSTR-1 — outward supplies (portal files)
Headers match the government GST Returns Offline Tool. Import each section into GSTR-1 on the portal — in this order:
- B2CS — retail sales without customer GSTIN (walk-in, small B2C)
- B2CL — large inter-state B2C (≥ ₹2.5L without GSTIN) — auto-split from your invoices
- CDNUR — credit notes to retail customers (no GSTIN)
- HSN summary — tax codes with quantity and UQC for portal upload
- B2B — invoices where the buyer gave a GSTIN
- CDNR — credit notes to GST-registered customers
GSTR-3B support
Outward tax summary (Table 3.1 style), purchase ITC estimate from your bills, and net payable hint — reconcile ITC with GSTR-2B before you claim.
CA review exports
Readable CSV copies of every section, invoice lines export for audit, and month-end GST summary by HSN — share via CA Access.
Monthly & annual
Pick a month for GSTR-1/3B filing, or load the full financial year for year-end workbook (GSTR-9 style review).
What we don't do: Simple Bills does not submit returns on gst.gov.in. Your CA or you upload the CSVs and file after checking GSTR-2B and vendor bills. Composition scheme (GSTR-4) is not supported — built for regular monthly filers.
How to file GST with Simple Bills
“GST file kya hai?” — yeh simple flow hai. Simple Bills prepares the numbers; you or your CA upload and file on the government portal.
-
Bill normally all month
Raise GST invoices, record credit notes, and log purchases in Simple Bills — same as every day. Tax (CGST/SGST or IGST), HSN, and customer GSTIN are captured on each bill. No separate GST workbook needed.
-
Run the month-end checklist
Before you export, open Reports → Month-end checklist. Fix anything flagged — overdue entries, purchases without bills, missing customer GSTIN on B2B sales. Cleaner books = fewer surprises at filing time.
-
Download the GST filing pack
Go to Reports → GST Filing Pack. Pick the month (or full year for annual review). Download “for portal” CSVs — B2CS, B2CL, B2B, CDNR, CDNUR, HSN — plus “your copy” sheets to email your CA. GSTR-3B outward summary and purchase ITC register are on the same screen.
-
Upload GSTR-1 via Offline Tool
On your computer, open the government GST Returns Offline Tool (from gst.gov.in). Import each CSV in this order: B2CS → B2CL → CDNUR → HSN → B2B → CDNR. Then log in to gst.gov.in and submit GSTR-1 for that month.
-
Reconcile ITC, then file GSTR-3B
For outward tax, use the GSTR-3B summary from Simple Bills. For purchase ITC, compare your purchase register with GSTR-2B on the portal — claim only what matches your vendor bills. Then file GSTR-3B on gst.gov.in.
-
CA review (optional)
Send your CA the readable CSV copies, or use CA Access (Company setup) so they can open GST reports and ledgers read-only — without your password. They check; you or they file on the portal.
Remember: Simple Bills packs the luggage — you still board the flight. We do not submit returns on gst.gov.in.
