Google Sheets or inventory software: know your breaking point
A shared spreadsheet is free, familiar and good enough for many small shops. It stops being enough at specific, predictable moments.
Google Sheets works well as a stock register for one location with one or two people updating it and a product list you can scroll through. Move to ready-made inventory software when several staff enter stock, when bills and stock must come from the same data, or when you need barcodes. Consider custom software only when godowns, branches or production steps outgrow what ready-made tools can follow.
Google Sheets
Best for: A single shop or small trader with one or two people updating stock and a product list short enough to scroll through.
- Free with a Google account, nothing to install
- Everyone already knows how a spreadsheet works
- Owner and staff see the same live copy on any phone
- Add a column the moment you need one
- Anyone with edit access can alter past entries
- One careless sort or paste can scramble the register
- Several branches and godowns become a maze of tabs
- No counter billing, barcode sales or GST invoices
- Gets slow and error-prone as rows and formulas pile up
Cost: Free on a personal Google account; business accounts on Google Workspace carry a per-user subscription.
Inventory software
Best for: Businesses with several staff entering stock, more than one location, barcode billing, or GST invoices that must draw on the same stock data.
- Every movement is recorded with a user and a time
- Stock by branch and godown, with transfers between them
- Barcode or QR scanning at billing and at receiving
- GST invoices, HSN codes and tax reports from one source
- Reorder alerts, plus batch and expiry tracking where needed
- Costs money, either a subscription or a one-time build
- Staff need training and discipline to record every movement
- Opening stock must be counted and loaded carefully
- Less freedom than a spreadsheet for one-off analysis
Cost: Ready-made apps run on a low monthly or yearly subscription; a custom inventory module typically costs ₹50,000–₹1,50,000 one time.
The short verdict
Stay on Google Sheets if you run one shop, one or two people touch the stock register, and bills come from a separate billing app or book. A great many small businesses are in exactly this position and do not need to spend anything yet. Tighten the sheet instead: protect the header row, use dropdown lists for item names, and keep purchases and sales on separate tabs.
Move to a ready-made inventory and billing app when three or more people update stock, when you want to scan barcodes at the counter, or when GST invoices and stock should come from the same place. A modest subscription handles this well for most retailers and traders.
Consider custom inventory software when you run several godowns or branches with transfers, batch and expiry rules, or production steps where raw material becomes finished goods, and the ready-made apps keep forcing workarounds.
A hardware store in Dindigul can run its stock from a Google Sheet for years without trouble. A distributor in Karur with two godowns, four salesmen and a van on the road usually cannot. The difference is not turnover. It is how many hands touch the stock figures and how many places the stock physically sits.
Fit: how many hands touch the stock
A spreadsheet is a superb tool for one careful person. The owner who updates purchases every evening, glances down the column of low items and reorders by phone is well served by it, and should not let anyone talk them out of it. Trouble starts when the billing clerk, the godown keeper and the accountant all edit the same file at different times of day, each with their own habits.
Five breaking points
- More than two people entering stock. Someone types over a formula, sorts one column without the others, or enters "PVC pipe 1in" where the sheet says "PVC Pipe 1 inch", and the totals quietly go wrong.
- Stock in more than one place. Branches and godowns mean transfers, and a transfer must reduce one location and increase another at the same moment. A spreadsheet does this by hand, so the figures drift apart.
- Barcodes. Once you print labels and want staff to scan rather than type, you need software that treats a scan as a transaction, not as text landing in a cell.
- An audit trail you can trust. Sheets keeps an edit history, but anyone allowed to edit can still change a past entry, so a shortage investigation turns into guesswork.
- GST. Invoices need HSN codes, the right rate per item and clean reports for returns, and moving goods or crossing turnover limits brings e-way bills and e-invoicing into the picture. Billing outside the stock sheet means entering every sale twice.
Total cost over time
Sheets costs nothing on a personal Google account, and a business Workspace account adds a per-user subscription. Ready-made inventory and billing apps charge a low monthly or yearly fee. A custom inventory module typically costs ₹50,000 to ₹1,50,000 once, plus hosting and maintenance. The cost people forget is the cost of wrong numbers: dead stock nobody noticed, a fast-moving item that ran out during the festival rush, or an hour every evening reconciling two files.
Speed to start and ownership of data
A sheet is ready in ten minutes. A ready-made app is ready in a day or two, once items and opening stock are loaded. A custom build takes weeks. On ownership, Sheets is excellent: the data is yours and exports in a click. With a ready-made app, check what you can export before committing, because an item master and years of history are tedious to rebuild. With custom software, the code and database are yours outright.
Integrations with billing, accounts and your online store
Sheets can be linked to forms and scripts, and a capable person can make it surprisingly useful. Inventory software is designed to connect: billing at the counter, purchase entries, exports to Tally, and stock sync with an online store so you never sell what is not on the shelf. Selling online as well as in the shop is often the moment to switch. Our article on billing and inventory software for small businesses walks through the options.
Support and scaling
Nobody supports your spreadsheet except whoever built it, and formulas break silently. Ready-made apps come with vendor support and updates. Custom software comes with whatever support you agree, which should cover fixes and changes as you grow. Scaling separates the routes most clearly: adding a branch to a sheet means another tab and another person to train, while adding one to proper inventory management software means another location in a dropdown.
What to do at each stage
- One shop, one or two people: stay on Sheets, with protected ranges and data validation switched on.
- Several staff, GST bills, barcodes: move to a ready-made billing and inventory app; our comparison of custom billing software and Vyapar explains when that is enough.
- Several godowns or branches: choose software with genuine multi-location stock, and label goods with a barcode and QR system so transfers are scanned rather than typed.
- Unusual stock flows: processors, manufacturers and distributors running van sales should look at custom software, as described for wholesale distributors.
If you are at stage four, VS Tech Builders can scope a custom system around the way your stock really moves. If you are at stage one or two, keep the money in the business for now.
Frequently asked questions
Can Google Sheets handle barcode scanning?
Partly. A USB or Bluetooth barcode scanner types the code into whichever cell is selected, so you can look items up with formulas, and some phone apps can send scans into a sheet. What Sheets cannot do is turn a scan into a sale that reduces stock, prints a bill and records who made it, all in one step. If counter scanning is the goal, use billing or inventory software.
How do we move from a spreadsheet to inventory software without losing data?
Clean the sheet first: one row per item, consistent names and units, HSN codes filled in, no merged cells. Most inventory software, ready-made or custom, can import a CSV export of that sheet. Then count physical stock on a quiet day and load that as opening stock, because spreadsheet figures often drift from what is actually on the shelves. Run both side by side for a week before trusting the new system.
Is Excel better than Google Sheets for keeping stock?
For one person on one computer, Excel copes well with large files and heavy formulas. Google Sheets is simpler when the owner checks stock from home while staff update it at the shop, because it lives online by default, though Excel files on OneDrive can be shared too. As stock systems both share the same weaknesses: no enforced rules, a weak audit trail and no billing. Knowing when to leave both matters more.
When is custom inventory software worth it over a ready-made app?
When your stock does not behave like shop stock. A rice mill turns paddy into rice, bran and broken rice. A garment unit tracks fabric by the roll, then cut pieces by size and colour. A distributor loads a van in the morning and settles it in the evening. Many ready-made apps handle these awkwardly. A custom module typically costs ₹50,000 to ₹1,50,000 and follows your actual flow.
