Inventorini for builders and contractors
Stop recounting cartons by hand. Stock is kept in the two units a godown actually deals in: full cartons and loose pieces. Open a carton and the pieces appear. Bill from either. Every bill shows what it earned, udhaar goes on each customer's own khata, and every shop gets a free storefront customers order from over WhatsApp. For builders and contractors, the fit is specific: site progress is reported by phone, and material orders are duplicated across sites.

What builders and contractors use it for
- Stock. Items held in cartons and loose pieces at once, with cost and sale price for both, and open or pack on every line.
- Billing. Bills drawing from either unit, with the profit on that bill shown as you write it and a warning under cost.
- Storefront. A public catalogue per shop with your own banner and brand colour. Customers build a cart and send it to you on WhatsApp.
- People. Owner and staff logins, username and PIN, an app lock behind the phone's own biometrics, and sessions you can revoke.

Questions people ask
- What counts as an entry in the free plan?
- A billable write: stock in, a sale, a bill, opening or packing a carton, or an audit. A bill, an Excel import and an audit each count as one no matter how many lines they contain. Reads, settings changes and storefront edits are free.
- What happens when the free plan ends?
- New entries stop and the app offers the paid plan. Nothing is deleted and everything stays readable. Subscribe and you carry on from where you were. The app warns you once you have used 160 of your 200 entries rather than at the wall.
- Can I sell in pieces from a sealed carton?
- Yes. Open the carton in the app, the pieces enter loose stock, and the carton count drops by one. The total never drifts.
- Can it stop staff selling too cheap?
- It warns them. Price a line below what that stock cost and the bill flags it as you write it, with the cost shown. It does not block the sale, since sometimes you do mean it, but nobody does it by accident.
- Can it keep my udhaar khata?
- Yes. Save each customer by name, with a mobile number if you want one. When you make a bill, write the customer's name and what they paid now; the rest goes on their khata. Old udhaar from your paper register can be added as an opening amount. Each customer's khata shows every bill, payment and old udhaar with the balance, and if someone pays more than they owe, the extra stays as advance. Only the owner can remove a wrong payment or old-udhaar entry, and bill entries stay with their bill.
- Does the storefront cost extra?
- No. It is included, and the orders come to your own WhatsApp number. We do not take a cut of anything sold through it, and the storefront never shows your stock quantities.
- Does the app show ads?
- No, on any plan. Ads were removed rather than tuned: at local banner rates a few hundred free shops would have earned less than one subscription, in exchange for a Contains ads label on a billing app.
- Do staff need their own logins?
- They can have them. The owner login sees everything; staff logins are scoped to counter work. A PIN reset signs every other device out.
- Is there an iPhone app?
- The web app installs on iPhone from Safari and works offline once installed. The native build is Android.
