Your stockroom, on the phone in your pocket
The four jobs you do every day, in the Android app. The same account and the same numbers on the web and on Windows.
Know what you have, in every location
On-hand, reserved and available stock for each shop, godown and warehouse. Move stock between them with an approval step.
Scan instead of typing
Read barcodes and QR codes with your phone's camera. Photograph a product label to fill in a new item's name. Print barcode labels for your shelves.
Bill with GST
Invoices with GSTIN, HSN/SAC codes and the CGST, SGST or IGST split, as a PDF or by email. Sales orders, purchases, payments and credit notes run off the same stock.
Reorder before you run out
When an item will run out before your supplier can deliver, you get an alert (a push notification on Android) and a draft purchase order to confirm.

A forecast for every item, from its own sales
A fast seller and a part that sells twice a quarter shouldn't be planned the same way. EvoWerk tries several forecasting methods on each item's past sales and keeps the one that would have predicted it best. From that, and from how long your supplier really takes, it works out when to reorder.
Three alerts run on every plan: an item about to run out, sales that suddenly jump or drop, and lots close to expiry.
- A likely range, not one number
- Every forecast shows the range sales will probably land in, so you can see how sure it is.
- New items borrow a pattern
- With under four weeks of sales, an item uses a profile from similar items until it has its own.
- Real delivery times
- Each supplier's lead time is measured from your own purchase-order receipts.
- Nothing is ordered without you
- Purchase orders stay drafts until someone confirms them.
How the forecast works
Five methods are backtested on every item's own history. The one with the lowest error (MASE, mean absolute scaled error) makes the forecast; near-ties go to the simpler method. Every forecast carries an 80% band.
- IntermittentCroston's method · SBA correction
Long gaps, then a movement: sizes and intervals forecast separately.
- TrendHolt
Level and slope tracked apart, for demand drifting one way.
- SeasonalHolt-Winters (ETS)
A shape that repeats, fitted once an item has two years of weekly sales.
- RepeatSeasonal naive
Same week last season, when that beats every fitted model.
- Steady8-week average
No trend and no season, so nothing is invented to fit one.

- safety_stockz × √(LT·σd² + μd²·σLT²)
- reorder_pointμd × LT + safety stock
- po_draftgrouped by supplier
- confirmationa person, always
The sudden-change alert fires when last week's movement sits a robust z-score of 3.5 or more from the item's own forecast. What-if runs (a different service level, lead time or demand uplift) save nothing.
Set up for your trade
Each workspace is set to one of six industries in Settings, and the menus and item fields follow it. One location or fifty.
Retail & distribution
Stock on hand, reserved and available at every location, transfers with approval, and barcode and QR scanning.
Apparel
Variants and bundles per style. Seasonal items get a seasonal forecast when their history shows one; Pro adds Google Trends.
Food
Lots with shelf life, earliest-expiry-first picking, storage conditions and quarantine holds. A recall lists every customer who got the lot.
Pharma
Lot status (available, quarantine, on hold, expired) and recalls across several lots, with emailed notices and a CSV or PDF report.
Hospital
Wards and stores as locations, staff limited to their own, expiry alerts, and WHO outbreak news matched to your items on Pro.
Light manufacturing
Bills of materials with assembly builds, unit conversions, landed cost, and FIFO, LIFO or weighted-average costing.
Records that hold up when something goes wrong
Lots get an expiry from a shelf-life rule or a typed date, and a status: available, quarantine, on hold or expired. Picking takes the earliest expiry first. One recall can cover several lots: it lists every customer who received them, emails the notices, and exports an audit report as CSV or PDF.

Lots and recalls appear in food, manufacturing, pharma and hospital workspaces.
Books that balance
Choose FIFO, LIFO or weighted-average costing. Every receipt, invoice, payment and credit note posts a double-entry journal entry. Trial balance, profit and loss and the balance sheet come straight off that ledger; an owner can lock a period, and a void posts a reversing entry instead of deleting anything.

Before you start
Is the free plan actually free?
Yes, and no card is needed. Free covers 1,500 active items, unlimited users and locations, forecasts, reorder points and purchase-order drafts, lots and recalls, barcode and QR scanning, GST invoicing and the ledger, on Android, the web and Windows. It shows ads, including full-screen ads in the Android app, and sends up to 20 emails a day. Lite adds Shopify and WooCommerce sync; Growth and Pro remove the ads and add the AI assistant and higher limits.
What does it run on?
Android from Google Play, any current web browser at app.evowerkintelligence.com, and Windows from the Microsoft Store. It is one account on all three. There is no iPhone or Mac app; on those, use the web app. Each user is signed in on one device at a time, and signing in somewhere new signs the last device out, so give each person their own login. Users are unlimited on every plan.
How does it decide what to reorder, and when?
It forecasts each item from its own sales history: it tries five methods on that history and keeps whichever would have predicted it best. It then adds safety stock based on how much the item's sales and the supplier's delivery times vary, and sets a reorder point: what you'll sell before a new delivery arrives, plus that safety stock. Items below it land in a draft purchase order for their supplier.
Will it order or change stock on its own?
No. Purchase-order drafts stay drafts until someone confirms them, alerts and outside signals arrive as recommendations, and every change the AI assistant proposes, such as a stock adjustment or a new purchase order, waits for your confirmation.
Does it handle GST and sales tax?
On invoices, yes. In India it applies GST rates, validates GSTINs, carries HSN/SAC codes and splits CGST, SGST and IGST on the invoice. The web app also prepares GSTR-1 and GSTR-3B for a period and exports your books to Tally; you file the returns yourself, and it does not generate e-invoices. In the US it carries base sales-tax rates for every state, lets you add local rates by ZIP prefix, tracks exemption certificates and their expiry, and can use Avalara AvaTax on your own license.
How do I pay for Lite, Growth or Pro?
In the app. On Android you buy Lite, Growth or Pro through Google Play; in the Windows app you buy Growth or Pro through the Microsoft Store. Both bill monthly or yearly, priced in your local currency, and the store takes the payment. The plan belongs to your workspace, so it applies on every device you sign in on. The web app has no checkout.
Where is my data, and can I take it out?
The app runs on Cloudflare, the API and database on Railway, and AI, OCR, file storage and email on AWS. Each business is kept separate, every change is logged, and the owner can export the whole workspace or erase it. Two-factor sign-in and single sign-on are not available yet.
