GST & e-Invoice
"GST is due and my files are everywhere." MGH Books quietly fixes that. Because every invoice and bill already carries the correct tax, your GST position is always up to date — and at filing time you get a clean summary and a portal-ready file. On higher plans it also generates e-Invoices (IRN) and e-Way Bills. Here's the whole picture, jargon decoded.
Read this first — how GST works here
- GST isn't a separate chore. It's computed on every invoice and bill as you go.
- Your net GST is always visible: Output GST (collected on sales) minus ITC (paid on purchases) = what you owe.
- MGH prepares; you file. It gives you the summary and a GSTR-1 file; you (or your CA) submit it on the GST portal.
- e-Invoice & e-Way Bill use government systems and need your own eligibility/credentials (and a higher plan).
What MGH does for GST
| Feature | What it does | Plan |
|---|---|---|
| Auto CGST/SGST/IGST | Correct tax on every invoice & bill | Shuruat |
| GST Summary | Output GST − ITC = net payable, live | Shuruat |
| HSN / SAC Summary | Rate-wise HSN totals (GSTR-9 Table 17) | Shuruat |
| GSTIN Validation | Check a GSTIN's format/state | Shuruat |
| GSTR-1 JSON Export | Filing-ready file for the GST portal | Pragati |
| e-Invoice (IRN/QR) | Generate IRN for B2B invoices | Unnati |
| e-Way Bill | Generate EWB for goods movement | Unnati |
- MGH prepares; you file. It produces the GSTR-1 summary and JSON; the return is filed by you/your CA on the GST portal.
- e-Invoice & e-Way Bill need your own credentials and eligibility on the government systems — and the Unnati+ plan.
- Rates & HSN are your responsibility. The app applies whatever rate/HSN you set on items — verify against current law.
- Accurate in, accurate out. Your GST is only right if invoices, bills and ITC are entered correctly.
GST as you work
There's no "do GST" button to dread — each invoice and bill already carries the right tax (item rate × place of supply). The Reports → GST screen simply rolls it up: output GST, Input Tax Credit, and net payable for the period.
help-shots/gst-01-summary.pngFile your GSTR-1 — step by step
Open the GST report
Go to 📜 Reports → GST and pick the period (month/quarter).
Review the GSTR-1 summary
Check the B2B, B2C and rate-wise breakdown against your invoices.
Export the JSON
On Pragati+, export the GSTR-1 JSON and upload it on the GST portal (or hand it to your CA).
help-shots/gst-02-gstr1.pnge-Invoice (IRN) & e-Way Bill
On Unnati+, generate an e-Invoice to get the IRN and signed QR for B2B invoices, and create e-Way Bills for goods movement — both via the government systems. Generated EWBs are kept in an e-Way Bill register for compliance.
help-shots/gst-03-einvoice.pngReconciliation & annual returns
For annual filings, the report library includes GSTR-9C reconciliation (books vs GSTR-9) and Form 168 (ex-26AS) reconciliation — see CA Reports & Financials for the full statutory set.
Real situations
📖 Monthly GSTR-1
At month-end, Sunil opens Reports → GST, picks the month, checks the B2B/B2C summary, exports the JSON (Pragati), and uploads it on the portal — minutes, not an evening of spreadsheets.
📖 Generating an e-Invoice
For a big B2B sale, Sunil (Unnati) generates the e-Invoice; the IRN and QR are added to his invoice automatically.
📖 Inter-state shipment
Shipping goods to another state, he generates an e-Way Bill from the invoice so the consignment is compliant on the road.
Words you'll see, in plain language
| Term | What it means |
|---|---|
| Output GST | GST you collected on your sales. |
| ITC | Input Tax Credit — GST you paid on purchases, used to reduce what you owe. |
| GSTR-1 | The return of your outward sales, filed monthly/quarterly. |
| GSTR-3B | The summary return where you pay the net tax. |
| GSTR-9 / 9C | Annual return / reconciliation (9C for turnover above the threshold). |
| IRN | Invoice Reference Number — the government ID for an e-Invoice. |
| e-Way Bill | A permit for moving goods above a value threshold. |
| B2B / B2C | Sales to registered businesses / to consumers. |
Troubleshooting
| What you see | Why | What to do |
|---|---|---|
| A sale taxed as IGST locally (or vice-versa) | Wrong place of supply on the invoice | Fix the place of supply; the GST recomputes |
| GSTR-1 export not available | It's a Pragati+ feature | Upgrade to export the JSON |
| e-Invoice / e-Way Bill missing | Unnati+ and portal eligibility needed | Upgrade and complete the GST-portal setup |
| Net payable looks too high | ITC not captured on purchases | Record purchase bills with GST/GSTIN |
Best practices
- Record purchases with GST so ITC always offsets your output tax.
- Reconcile the GST summary against your invoices before exporting.
- Keep item HSN/rates correct — they drive every figure.
- File on time on the portal; MGH gets you filing-ready, the portal does the submission.
FAQ
Does MGH Books file my GST return automatically?
No. It prepares the summary and GSTR-1 JSON; you upload/file on the GST portal.
A sale shows IGST instead of CGST+SGST — why?
The tax follows the invoice's place of supply. If it's another state, IGST applies — correct it if wrong.
Do I need anything special for e-Invoice?
Yes — e-invoice eligibility and access to the government e-invoice system, plus the Unnati+ plan.
Where do annual returns / reconciliation live?
In the CA reports library — GSTR-9C and Form 168 (ex-26AS) reconciliation. See CA Reports.
- Sales & Purchases → output GST and ITC come straight from documents.
- Items → HSN/SAC and rates drive the tax.
- Reports → GSTR-1, HSN Summary, GSTR-9C, Form 168 (ex-26AS) recon — see CA Reports.
