Cost of a Node.js (Backend Only)
pos & inventory app.

a POS + Inventory System on Node.js (Backend Only) is not one price, it is three. Knowing which one applies to you before you collect quotes will save you weeks of confusing back and forth. An MVP that proves the idea with early users runs ₹30,000–70,000. A production-ready version with the features pos + inventory system needs to keep users runs ₹1.5–3.5 lakh. Enterprise-grade builds, with real compliance and integration work, run ₹6–15 lakh+. Backend/API layer only It shapes where in that range you will actually land, since it directly affects the engineering effort per feature. A suspiciously low quote for a scope that clearly needs the middle or top tier should worry you more than a high one.

Fits teams that already have a frontend or mobile client and need the server/API layer built or rebuilt independently. In practice, for something like a POS + Inventory System, that means a specific bet about where engineering time goes. Every stack choice is really a choice about which problems you make easy and which ones you make harder. Cross-platform tools give you shared logic and faster updates across devices. Native development gives you tighter control over performance and platform behavior. pos + inventory system tends to make this trade-off very real, not abstract, because it has genuine needs, like fast response times or deep device access, that either fit the stack's strengths or force extra work. Knowing where your product sits on this before you start avoids an expensive surprise later.

What Actually Drives The Price

If you want to know why one pos + inventory system quote comes in at half the price of another, here is the single factor that moves the price more than anything else: Offline-first reliability and whether multiple store locations need real-time stock sync. Two products in this category can share a name and a similar feature list while needing very different amounts of engineering work, because one keeps this part simple and the other does not. Here is a real example. Two teams scope what looks like the same app, but one quietly assumes the simple version while the other needs a much more complex version of the same requirement. That gap alone can add weeks of work that never shows up on a feature list.

How We Scope And Build It

Good studios do not quote a POS + Inventory System off a feature list alone. They run a founder workshop first, usually a few hours, to pressure-test the actual scope, users, and trickiest parts of the product before writing down any estimate. That workshop should produce a rough architecture and a prioritized backlog, not just a list of screens. Once development starts on Node.js (Backend Only), work should happen in sprints with a working demo at the end of each one, an actual build you can click through, not a slide deck. Weekly demos keep the founder in the loop without turning into daily interruptions that slow the team down.
