Everything a small business needs for GST

One entry updates your books. No re-typing, no month-end scramble.

GST invoices in seconds

Pick a product and its HSN, GST rate and unit fill in. CGST + SGST or IGST is chosen from the place of supply.

HSN summary, built for you

Every invoice feeds the HSN-wise summary for GSTR-1. Export it as a CSV at month end.

GST filing preparation

GSTR-1 and GSTR-3B figures laid out table by table, with a copy button next to every number.

E-way bill ready

Invoices above your limit are flagged. Part A and Part B data is prepared for the portal, and validity is tracked.

Stock, purchases, payments

Purchase bills add stock and input credit. Payments clear the oldest invoice first. Debtors and creditors stay current.

PDF invoices and share links

Download a clean PDF or send a secure link by WhatsApp or email. Customers can pay by UPI from the link.

Your team, with roles

Invite your accountant and staff. Owner, admin, accountant, staff and view-only roles, enforced by the database.

Permanent activity log

Every change is recorded with who did it and when, and nobody can edit it. Staff can't quietly change a bill.

Several companies, one login

Run separate books for each business you own or manage. Nothing is shared between them.

Extra tools for service and AMC businesses

From customer complaint to GST invoice, without the paperwork

For businesses that install, repair and maintain equipment. Included in the Business plan, and in every free trial.

Customer asks for service

They call you, or scan the QR sticker on their machine and send a request. No app to install.

Create the job

Customer, machine and AMC or warranty cover fill in. Pick a technician and a visit date.

Technician does the work

On their phone: start the job, call the customer, note what was fixed, add the parts used.

Customer signs on the phone

A finger signature confirms the work is done, with name, date and time.

GST invoice in one tap

Parts and service charges become a GST invoice. Stock, balances and GST update together.

Service jobs and technicians

Every complaint becomes a job with a technician, visit date, priority, work notes and parts used. See what's open, overdue and ready to invoice.

Unique

QR service stickers

Print a QR sticker for every machine you install. Customers scan it to see their AMC or warranty status and request service, and you stay the number they call.

AMC contracts and renewals

Covered equipment, planned visits, instalment invoices and renewal reminders. Renew with a price change in two clicks.

Visit schedule

Planned AMC visits and service jobs on one calendar, per technician. Turn a planned visit into a job with one tap.

Equipment register

Every machine at every customer, with serial number, location, install date, warranty and full service history.

Signed proof of work

Signed job sheets end "your technician never came" disputes. AMC jobs are logged as service visits on their own.

Questions

Is AccBuddy only for service businesses?

No. Shops, wholesalers, traders, manufacturers and contractors use the GST billing, stock, purchases and payments. The service and AMC tools come with the Business plan, and every 14-day free trial includes everything so you can try them.

Does AccBuddy file my GST returns?

AccBuddy prepares every figure for GSTR-1 and GSTR-3B and the HSN summary, ready to copy into the GST portal. Filing itself happens on the GST portal. Please have your accountant review figures before filing.

Can AccBuddy generate e-way bills directly?

Not yet. AccBuddy flags which invoices need one, prepares all Part A and Part B details and tracks validity. You generate it on the e-way bill portal and record the number in AccBuddy.

Do my staff or technicians need to install an app?

No. AccBuddy works in any phone or laptop browser. Invite them to your team with the right role and they can start straight away.

How do the QR service stickers work?

AccBuddy prints a sheet of QR stickers, one per machine, on standard A4 label sheets. Your customer scans a sticker with their phone camera to see that machine's AMC or warranty status and last service date, call or WhatsApp you, or send a service request. They only see that machine's details, never your other customers or your prices.

What happens when my trial ends?

Nothing is deleted. Your books become read-only until you choose a plan, so you can still view and export everything.

Who can see my data?

Only the people you invite to your company. Our team does not access customer books except when you ask for support.
