Monthly Bookkeeping & GST Filing
When should I hire an accountant?
Most founders wait until their books are already a mess. The better question is what your time is actually worth doing instead.

What does monthly GST and bookkeeping actually cover for a D2C brand?
Monthly GST and bookkeeping covers sales and purchase reconciliation, GSTR-1 and GSTR-3B filing, input tax credit matching against GSTR-2B, and keeping books current enough to support a loan application or investor question at any time. For D2C brands specifically, this also means reconciling marketplace settlement reports against GST filings — a step generic bookkeeping often misses.
Who this applies to
Any GST-registered business — most relevant for D2C and marketplace sellers with multiple monthly settlement reports to reconcile.
Exceptions
Businesses on the Composition Scheme file quarterly (CMP-08) rather than monthly, and have simpler — though more restricted — filing obligations.
Cost
No government fee for filing itself. Our monthly fee depends on transaction volume and number of sales channels — quoted after reviewing your current book of business.
Timeline
Ongoing, monthly — GSTR-1 due by the 11th, GSTR-3B by the 20th of the following month.
Documents required
- Sales and purchase invoices for the period
- Bank statements
- Marketplace settlement reports (for e-commerce sellers)
- Previous period's GSTR-2B for ITC reconciliation
Risks
- Input tax credit mismatches from trusting your own purchase register instead of GSTR-2B
- Late filing penalties and interest for missed deadlines
- GST notices triggered by mismatches between filed returns and marketplace TCS reports
Practical example
A small D2C seller filed GSTR-3B on time every month but never reconciled against GSTR-2B, trusting their own records instead. Eight months in, a supplier's late filing had created a ₹40,000 input tax credit mismatch that had been invisible the whole time — a ten-minute monthly check would have caught it in month one.
At a glance
| Filing type | Frequency | Who it applies to |
|---|---|---|
| GSTR-1 + GSTR-3B | Monthly | Regular scheme taxpayers |
| CMP-08 | Quarterly | Composition scheme taxpayers |
| GSTR-9 | Annually | Most GST-registered businesses above the exemption threshold |
Who is this for?
This may not be the right service if… If your transaction volume is genuinely tiny and you enjoy doing it, there's no urgency — but most people underestimate how quickly this becomes a real time cost.
What problem does this solve?
Most people believe…
Bookkeeping is just data entry.
Reality
Reconciliation, ITC matching, and category-correct entries are what actually prevent GST notices — it's more than typing numbers in.
I can catch up all at once at year-end.
Reality
Monthly closing catches small errors early. A year of backlog usually means bigger, harder-to-fix problems.
Any accountant can do this the same way.
Reality
Consistency and communication matter as much as accuracy — a dedicated relationship beats a rotating one.
