EVE vs Spreadsheets
When spreadsheets stop working for Shopify inventory planning — the specific failure points fashion brands hit, and what changes with variant-level forecasting.
What Spreadsheets is
Most Shopify fashion brands start inventory planning in Excel or Google Sheets, exporting sales data and building reorder calculations manually.
Where Spreadsheets is strong
- Free, and every founder already knows how to use them.
- Completely flexible — a spreadsheet models exactly your business, with no vendor's assumptions imposed.
- Entirely under your control, with no data leaving your systems and no subscription.
- Genuinely sufficient at low SKU counts. Below roughly a hundred variants, a well-built sheet is hard to beat.
Documented considerations
- Spreadsheet accuracy degrades as variant count grows. Fashion SKU counts compound multiplicatively — styles × colours × sizes — so a modest catalogue reaches four figures quickly.
- Merchants publicly describe spending hours per week maintaining reorder spreadsheets before moving to dedicated tools.Source: Multiple public Shopify App Store reviews across inventory apps
- A spreadsheet reports the past accurately but does not monitor continuously — it is only correct at the moment it was last updated by hand.
How EVE approaches it
- EVE reads Shopify sales history directly, so the underlying numbers do not need manual export and refresh.
- Variant-level velocity is calculated per size and colour rather than maintained by hand.
- Stockout risk and dead-stock capital are monitored continuously rather than recalculated when someone remembers to.
Which one fits
Choose Spreadsheets
Brands under roughly a hundred variants, or with unusual planning logic that no off-the-shelf tool models correctly.
Choose EVE
Brands where variant count has outgrown what a person can accurately maintain by hand each week.
Frequently asked questions
When should a Shopify brand stop using spreadsheets for inventory?
There is no universal threshold, but the practical signal is when the sheet is no longer updated on schedule, or when stockouts and overstock are being discovered after the fact rather than predicted. For fashion brands this typically coincides with variant counts moving into the high hundreds.
Are spreadsheets actually bad for inventory planning?
No. A well-built spreadsheet is genuinely effective at small scale and gives you complete control. The failure mode is not the tool, it is that manual maintenance does not scale with a multiplying variant matrix.
