Last reviewed: 25 September 2026. Most accounts teams lose hours every week to repetitive spreadsheet work - reconciling, re-keying and rebuilding the same reports. A little automation with formulas, pivots and scripts turns that effort into review time and cuts errors. Here are ten practical ways to automate an Indian accounts function in Google Sheets or Excel, with working formulas for the three that save the most time.
At a glance
Ten practical use cases
- Bank reconciliation - match bank statements to the ledger with lookup formulas and flags.
- GST ITC matching - reconcile the purchase register against IMS actions and GSTR-2B.
- TDS tracker - monitor deductions, thresholds and due dates in one sheet.
- Receivables ageing - auto-bucket invoices by age to chase collections.
- Cash-flow tracker - a rolling view of inflows, outflows and runway.
- Invoice register - standardised entry with validations and numbering.
- Expense categorisation - rules-based tagging for faster books.
- MIS dashboard - one-page view of revenue, margin, cash and compliance.
- Payroll and reimbursement sheets - templated calculations with checks.
- Scheduled reports - Apps Script or macros to refresh and email reports automatically.
Three worked examples
1. Bank reconciliation with a match key
Put the bank statement on one tab and the ledger export on another. On both, add a helper column that joins the date and the amount into one key, for example in column E: =TEXT(A2,"yyyymmdd")&"|"&TEXT(ROUND(D2,2),"0.00"). On the bank tab, look each line up in the ledger:
=IFERROR(XLOOKUP(E2,Ledger!E:E,Ledger!B:B),"Unmatched")
Filter on "Unmatched" and what is left is your reconciliation: cheques issued but not presented, bank charges not yet booked, and receipts sitting in suspense. Where banks post a day late, add a second pass that matches on amount and reference only.
2. Purchase register against IMS and GSTR-2B
Since the Invoice Management System went live on the GST portal, supplier invoices land in IMS first. You accept, reject or keep each one pending, and GSTR-2B is generated from those actions. The sheet therefore has two jobs: flag differences while you can still act in IMS, and tie the final GSTR-2B to the ITC claimed in GSTR-3B.
Build the key as supplier GSTIN plus a cleaned invoice number: =UPPER(B2)&"|"&UPPER(TRIM(SUBSTITUTE(C2,"/",""))). Then pull the taxable value from the 2B download with =XLOOKUP(F2,GSTR2B!F:F,GSTR2B!H:H,"Not in 2B") and set a status column:
| Status | Meaning | Action |
|---|---|---|
| Matched | Same GSTIN, invoice and value | Accept in IMS; claim |
| Value mismatch | Difference above your tolerance, say ₹10 | Ask the supplier to amend before accepting |
| Not in 2B | Booked by you, not uploaded by the supplier | Hold the ITC and follow up |
| Not in books | In IMS or 2B, not in your register | Check for a missing bill or reject if not yours |
3. Receivables ageing in one formula
With the due date in column D, =IFS(TODAY()-D2<=0,"Not due",TODAY()-D2<=30,"1-30",TODAY()-D2<=60,"31-60",TODAY()-D2<=90,"61-90",TRUE,"90+") puts every open invoice in a bucket. A pivot on customer by bucket gives the collection list, and conditional formatting on "90+" makes the problem accounts obvious.
Feeding the sheets from Zoho Books
If your books are on Zoho Books, export the bank transactions, the invoice and bill lists, and the receivables report as XLSX or CSV on a fixed day each month, and paste them into the raw-data tabs. The formula tabs then refresh themselves. For teams who want no manual step, an Apps Script can call the Zoho Books API on a schedule and write the data into the same tabs. Keep the raw tabs untouched and do every calculation on separate tabs, so a fresh export never breaks a formula.
The same sheets for overseas clients
For businesses in the US, UK or UAE, and for Indian subsidiaries of foreign groups, the logic is the same but every reconciliation needs a currency column and an FX line. A simple example for books kept in rupees:
| Item | USD | Rate | ₹ |
|---|---|---|---|
| Invoice booked | 5,000 | 83.10 | 4,15,500 |
| Amount received in bank | 4,970 | 83.40 | 4,14,498 |
| Bank charges deducted | 30 | 83.40 | 2,502 |
| Exchange gain (5,000 × 0.30) | - | - | 1,500 |
The check column confirms that ₹4,15,500 + ₹1,500 equals ₹4,14,498 + ₹2,502; if it does not, the line is flagged. The same close pack - bank reconciliations, ageing, accruals and a variance note - serves the monthly review whether the client is in Thane or Texas. Our outsourced bookkeeping and accounting for foreign firms runs on exactly these templates.
Start simple, then scale
Begin with formulas, pivot tables, data validation and conditional formatting - most quick wins need nothing more. When a task is repetitive and rule-based, add Google Apps Script or Excel macros for scheduled, one-click automation. Feed structured exports from your accounting software so the sheets stay current.
Frequently asked questions
How can automation help an accounts team?
By removing repetitive manual work - reconciliations, data entry, report building - automation cuts errors and frees the team for review and analysis. Even simple formulas, pivot tables and templates deliver large time savings.
Do I need to code to automate spreadsheets?
No. A great deal can be done with formulas, pivot tables, data validation and conditional formatting. For heavier tasks, Google Apps Script or Excel macros add scheduled and one-click automation, but they are optional.
What accounting tasks are easiest to automate first?
Bank and ledger reconciliation, GST input tax credit matching, TDS tracking, invoice and receivables ageing, and monthly MIS dashboards are the usual quick wins.
Does the GST Invoice Management System change the ITC matching sheet?
Yes. Supplier invoices now appear in IMS on the GST portal first, where you accept, reject or keep them pending, and GSTR-2B reflects those actions. Match the purchase register against IMS while you can still act on an invoice, then tie the final GSTR-2B to the ITC you claim in GSTR-3B.
Can spreadsheets connect to my accounting software?
Yes. Exports from tools like Zoho Books, Tally or your ERP can feed structured spreadsheets, and Apps Script or add-ons can automate the refresh and reporting.
How does automation reduce errors?
By replacing manual copy-paste with formulas and validations, standardising templates, and adding checks that flag mismatches - so problems are caught before they reach the books or a return.
Is Google Sheets or Excel better for this?
Both work. Google Sheets is strong for real-time collaboration and cloud automation via Apps Script; Excel is powerful for large data and complex models. The right choice depends on your team and data size.
What is an MIS dashboard?
A single view of your key numbers - revenue, receivables, cash, GST and TDS positions - updated from your data, so management sees the picture without digging through ledgers.
Do the same sheets work for overseas clients?
Largely, yes. Bank reconciliation, ageing and the month-end close pack are the same logic in any country; what changes is the currency handling and the local tax columns. For US, UK or UAE books we add a currency column, the booking and settlement rates, and an FX gain or loss line to each reconciliation.
Can you build these for my business?
Yes. We design reconciliation trackers, GST/TDS tools and MIS dashboards tailored to your workflow, and set up the automation so your team can run them easily.
