Accounting software: frequently asked questions
What is Fatmicky Accounting?
Fatmicky Accounting is cloud GST billing and accounting software for businesses. Create GST invoices, record purchases and expenses, track who owes you and whom you owe, and get your profit & loss, balance sheet and GST summaries, all in your web browser.
Is it GST compliant?
Yes. Invoices show GSTIN, HSN/SAC and place of supply, and tax is split into CGST + SGST for intra-state sales or IGST for inter-state sales automatically. Credit notes, debit notes and input tax credit on purchases and expenses are handled too.
Can I file GSTR-1 and GSTR-3B from it?
Fatmicky prepares GSTR-1 (B2B, B2C Large, B2C Small, credit notes, HSN summary, nil/exempt and documents issued) and GSTR-3B summaries with CSV export, so filing on the GST portal is quick. Always verify the figures before you file.
Do I need to know accounting?
No. You work with invoices, bills, payments and expenses, like you already do. Fatmicky writes the double-entry accounting behind every document, so your ledgers, trial balance and balance sheet are always up to date.
Does it track stock?
Yes. Sales reduce stock, purchases add to it and returns reverse it. Set a low-stock alert per item and see stock value in the stock summary and balance sheet.
Can I use it with Fatmicky POS?
Yes, with the same account. Your businesses and your team are shared, so you switch between POS and Accounting from the apps menu without signing in again.
Is my data safe?
Your books are stored in the cloud, separate for every business, with admin, accountant and staff roles so each person sees only what they need.
