21 small business accounting tips I wish I knew in my first year
When I started my services firm in Pune in 2019, my "accounting system" was a WhatsApp folder called bills. It cost me ₹1.4 lakh in ITC I never claimed and one very awkward call from a GST inspector. Six years, three CAs and one nearly-fatal cash crunch later — here are the twenty-one habits that would have saved me all of it.
Invoicing habits
1. Send an invoice the same day you deliver
The gap between "job done" and "invoice sent" is where 40% of Indian receivables get delayed. If your client can't pay you until they have an invoice, giving them a two-week head start on excuses is the surest way to invite one.
2. Keep an invoice-number series per financial year
Reset the series on 1st April. Format: INV/25-26/001. Never repeat a number, never skip one. Read our detailed guide.
3. Always mention a due date
Studies from Xero and QuickBooks show invoices with a specific due date get paid ~1.4× faster than those saying "payable on receipt". Use "Payment due by [date]" — not vague terms.
4. Add UPI ID + bank details on every invoice
Half your clients want to pay from their phone. If your UPI ID is at the bottom of the PDF, you'll get paid before they close the app. Our invoice generator lets you add a Notes block for this.
Tax hygiene
5. Reconcile GSTR-2B with your purchase register every 5th of the month
Every ITC rupee you skip is a rupee of tax you're paying twice. Set a recurring calendar reminder.
6. Pay advance tax quarterly if your income exceeds ₹10,000/yr in tax
Missing 15 Jun / 15 Sep / 15 Dec / 15 Mar due dates attracts interest under section 234B and 234C. Automate it in your accounting software.
7. File GSTR-1 by 11th and GSTR-3B by 20th — even if there's zero turnover
Late filing = ₹50/day (₹20 for nil return) per act, capped but painful. The GST portal auto-reminds you three days before due date.
8. Keep separate ledgers for personal and business
If you're a proprietor, this is optional but life-changing. A dedicated current account and a personal savings account with zero mixing makes ITR filing and audit trails ten times easier.
9. Book expenses monthly, not quarterly
Old receipts fade, memory fades faster. Book every invoice, receipt and expense within seven days. If you're on Tally, do it Fridays.
Cash flow
10. Ask for 30–50% advance on projects over ₹50,000
Not for trust reasons — for commitment. Advances filter out the "just curious" clients from the serious ones.
11. Never let a receivable cross 60 days without a written follow-up
Send a polite reminder at day 15, a firm reminder at day 30, a formal letter at day 45, and a legal notice at day 60. See our reminder email templates.
12. Track "days sales outstanding" (DSO) every month
DSO = (accounts receivable ÷ total sales) × days in period. Under 45 days is healthy; 60+ needs attention; 90+ is a crisis.
13. Keep three months of fixed expenses as reserve
Rent, salaries, EMIs, utilities, subscriptions. Whatever fixed money you burn monthly × 3 = the buffer you keep untouched in a liquid instrument.
Software and tools
14. Use one accounting tool, not four
Tally for books, Excel for tracking, WhatsApp for follow-ups, Google Sheets for GST — this is where startups die of paperwork. Pick one primary tool and force everything through it.
15. Use a free invoice generator until you cross 200 invoices/month
Below that volume, a subscription tool is a waste. Our tool handles it free.
16. Enable 2FA on all financial accounts
Bank, GST portal, income-tax portal, payment gateways. India lost ₹7,489 crore to cyber fraud in 2023-24 — half of it via basic phishing.
Documentation
17. Scan every physical receipt within 48 hours
Thermal paper receipts fade in 3–6 months. Use Google Drive → Scan feature.
18. Maintain a "clients master" spreadsheet
Columns: name, GSTIN, address, contact, payment terms, TDS applicable, last invoice number, notes. Update it every time you send an invoice.
19. Store all contracts in one folder, named by client
Cloud (Drive/Dropbox) with a clear folder hierarchy. If your CA asks for a five-year-old MSA and it takes you an hour to find it, you're bleeding time.
Compliance calendar
20. Print the tax calendar on 1st April every year
Stick it above your desk. TDS returns (30 Jul / 31 Oct / 31 Jan / 31 May), GSTR-1, GSTR-3B, GSTR-9, GSTR-9C, ITR, ROC filings — everything on one A4 sheet.
21. Book a CA review meeting every quarter, not once a year
The annual "March scramble" costs 3× more than four quarterly reviews. And your CA can flag issues while they're still cheap to fix.
