How to Choose Invoice Software in India

This is written by a vendor, so read it as such. What follows is the set of questions we think decide whether billing software will work for an Indian business โ€” including the ones where we would want you to check us as carefully as anyone else.

Last reviewed 28 July 2026.

Start with how it handles GST, not the invoice design

Every product will show you a good-looking invoice. The differences that cost you money are underneath.

The first question is whether the software decides the tax head for you. An invoice between two states carries IGST; within a state it splits into CGST and SGST. If that decision is a dropdown someone fills in, it will eventually be filled in wrongly, and you find out at filing.

  • Is CGST/SGST versus IGST derived from the two states, or chosen manually?
  • Are abolished slabs โ€” 12 and 28 percent โ€” still selectable?
  • Is GST added on top of the amount you enter, or backed out of it?
  • Can you search HSN and SAC codes while building a line item?

Check what happens at filing time

Billing software earns its cost at the end of the month, not while you are typing. If your returns are prepared from a separately re-keyed copy of your sales, the books and the filing can disagree and reconciling them is your problem.

  • Does it export GSTR-1 data directly from your invoices?
  • Can it summarise GSTR-3B figures?
  • If you need e-invoicing or e-way bills, are they included or extra?

Think about your second GSTIN and your second person

Plenty of tools are fine for one business and one user, and awkward beyond that. It is worth knowing the answer before you are in that position rather than after.

  • Can you run multiple GSTINs on one login, with separate numbering?
  • Is customer data shared across those businesses or duplicated per business?
  • Can staff get their own logins, with limits on what they can see?
  • Are those limits enforced on the server, or only hidden in the interface?

Test getting your data out before you put it in

This is the check most people skip and most regret. Export capability is easy to verify during a trial and very hard to obtain later.

  • Can you export invoices, customers and payments in a usable format?
  • Is there a documented API?
  • If you use Tally, is there a compatible export?

Model the price against your own volume

Headline prices are not comparable until you apply them to how much you actually bill. Per-user, per-invoice and flat pricing diverge sharply as you grow, and the cheapest tier is rarely the one you end up on.

Where we stand

WeSaveTax answers the GST questions above automatically, exports GSTR-1 and GSTR-3B data from your billing records, supports multiple GSTINs under one login, and lets you export or pull your data through an API. The pricing page has current figures and plan limits.

It is not a full accounting package, and it does not file returns for you. If those are what you need, they are a different purchase.

Frequently asked questions

Not for GST reasons. You may still want invoicing software for numbering, records and payment tracking โ€” and if you register later, having your customers and items already in one place makes the switch easier.

For low volume and simple needs, often yes. The usual limits are invoice count, emailing, reminders and returns data. Work out which of those you will need within a year and check whether the free tier still covers you.

It varies by volume and features. Compare on what you will actually use rather than the headline tier, and check whether the price is per user, per invoice or flat, because that is what determines the cost as you grow.
