What is a GST invoice app?
A GST invoice app lets you create a tax invoice on your phone instead of waiting to reach a computer. It should apply the right CGST, SGST or IGST, keep working when the network drops and sync to your books afterwards. CRM Force provides this on Android and iOS, backed by the same ledgers, stock and customer records you use on the web.

Why choose CRM Force
Why Mumbai teams choose CRM Force as their GST invoice app
Mumbai moves fast and travels a lot: local trains, site visits, client offices, market lanes. An invoice app has to work in those conditions, not only at a desk.
Works when the network does not
Offline mode means a weak signal on a train or in a basement does not stop billing.
More than an invoice maker
The same app carries leads, follow-ups, attendance and approvals, so field staff use one app, not four.
One set of books
What you raise on the phone appears in the same ledgers and GST reports as the web.
No per-user surprise
A flat plan from ₹9,999 per year with no per-user or per-app add-ons.
Start free, no signup wall
Try the free invoice generator first, then the 14-day trial for the full app.
Built in India for Indian GST
GSTIN, state-wise tax, e-way bill and Tally export are part of the plan.
Tip: store customer GSTINs once on the web, then your team only picks customers on the phone. It is faster and far less error-prone than typing on a small screen.
Is there a GST invoice app that works offline?
Yes. The CRM Force Android and iOS app has offline mode, so you can keep creating invoices when the network is weak and sync afterwards.
Ask for a quick demo of offline mode on your own phone during the trial.
Can I make a GST invoice on my phone for free?
The free GST invoice generator works in a mobile browser with no signup and is good for one-off invoices. For ongoing billing, ledgers and stock, use the 14-day free trial of the full app.
Does the app handle CGST, SGST and IGST?
Yes. The tax applied depends on the customer’s state, so local sales use CGST and SGST and inter-state sales use IGST.
How much does a GST invoice app cost in Mumbai?
CRM Force starts at ₹9,999 per year, with a 14-day free trial and no credit card. The app is included, not an extra charge.

How to start with the GST invoice app
- Register free. Create your account and add your business GSTIN and logo.
- Add customers and items. Do this once on the web, where a larger screen makes it quicker.
- Install the app. Sign in on Android or iOS with the same login.
- Raise an invoice. Pick the customer, add items, confirm the GST split and save.
- Check the books. Open the sales register or ledger on the web and see the invoice there.
When an app beats a desk
Many Mumbai businesses lose days of billing because invoices wait until someone returns to the office. A technician finishes a job at 4pm, a sales person agrees a deal at a client office, a wholesaler gets an order on a market visit. Billing on the spot shortens the time to invoice, and shortening that time is the cheapest way to improve cash flow.
It also reduces mistakes. Details captured at the point of sale are fresher and more accurate than details remembered at the end of the day.
Questions to ask about any GST invoice app
- Does it work offline, and what happens when it reconnects?
- Do invoices land in real ledgers or only in a list?
- Is the price per user, per invoice or flat?
- Can your accountant get Tally-format data?
Also included
