Your spreadsheet was right, once.
Every inventory spreadsheet is accurate at the moment someone stops editing it. Invistock replaces the file with a live system: one availability figure per item and warehouse, updated by every scan, sale and receipt — and your old sheet becomes the import file.
The moment the spreadsheet breaks
The warehouse copy and the office copy diverge silently, and the argument starts at month-end. Files don't merge movements; systems do.
A sheet records what someone remembered to type. It never saw the carton that arrived short or the pick that grabbed from the wrong bin.
A cell overwrite has no author, no reason and no timestamp. When a number looks wrong, there's nothing to investigate — only someone to blame.
The sheet, versus the system.
| Excel / Google Sheets | Invistock | |
|---|---|---|
| The stock number | As of the last manual edit, per copy of the file | Live per item, warehouse and bin — updated by every movement |
| Receiving stock | Typed from the delivery note, later, maybe | Scanned against the purchase order at the dock |
| Counting | Print, walk, type, reconcile | Cycle counts from a phone, variances flagged instantly |
| Multiple warehouses | One tab per site, reconciled by hand | One ledger, transfers visible in transit |
| Who changed what | Cell edit history, if anyone checks | Every movement has an owner, a reason and a document |
| The books | A second spreadsheet, or re-keying into an accounting app | Optional built-in ledger — movements post themselves |
| Cost | Free, plus everyone's hours and the write-offs | Scoped to the modules you switch on |
Spreadsheets are genuinely fine for a single stockroom with one careful owner. The comparison above describes what changes when more people, sites and documents enter the picture.
What actually happens when you switch.
The reason teams stay on a broken sheet isn't love — it's fear of the migration. Here is the honest shape of it.
Your sheet is the import file
Items, warehouses and opening quantities import from the spreadsheet you already have. Columns map once; you don't re-type a catalog you spent years building. Most teams import and run their first live cycle count within a week.
The first count is the reset
Opening quantities are only as good as the sheet was — so the first cycle counts, done an aisle at a time from the mobile app, correct reality without a shutdown weekend. From that point the number maintains itself: every receipt, pick, adjustment and transfer writes to the ledger the moment it happens.
Nobody relearns their job
The warehouse scans instead of typing. The office reads the same availability screen instead of asking for the latest file. Roles control who can adjust, who can approve and who can only read — accountability the sheet never had.
The books can come later
Start with pure stock control if that's the pain. The accounting module can switch on afterwards — chart of accounts, posting rules, and from then on a goods receipt becomes a journal entry without anyone re-keying it into a second spreadsheet.
Sheet to system, in a week.
Switching questions
Import items, warehouses and opening quantities directly from your sheet. Column mapping happens once, on the import screen — no consultants required.
