A till gives you a number. A POS gives you the sale it came from.

Does a POS update inventory?

It causes the update rather than owning it. A completed sale is a stock event: the items on the receipt left the business, and the stock record has to reflect that. In a well-separated setup the POS reports what was sold and the inventory system applies it to on hand and available, so there is one stock truth rather than a counter figure and a stock figure that disagree by Friday. A POS with a stock number of its own is fine in one shop and becomes the problem the moment there is a second one.

Does a POS include CRM?

It includes the part of the customer that belongs to the sale — who bought, at which outlet, what they took and when — and that is genuinely useful on its own. It is not a CRM. A CRM owns the wider relationship: leads, conversations, pipeline, follow-up and everything that happens away from the counter. Retail businesses often want both, and the honest arrangement is for the POS to record the purchase and hand the customer context on, rather than growing a second half-built relationship tool inside the till.

What is the difference between POS and an inventory management system?

A POS owns the retail transaction: the sale, the basket, the outlet and counter, the payment and the receipt. An inventory management system owns stock state: what exists, what is committed and what is genuinely available, and every movement that changed those. They meet at two moments and nowhere else — the counter asks what is available before it sells, and reports what was sold once it has. Many small retailers run a POS with a stock count inside it and manage perfectly well; the arrangement stops working when a second outlet or an online store starts asking the same question and getting a different answer.

What is the difference between POS and ecommerce software?

They are the same commercial event in two completely different situations. Ecommerce owns the online journey — browsing, choosing a variant, cart, checkout and the order that follows. POS owns the in-store transaction, where the customer is physically present, the item is in their hand and the sale has to complete in seconds at a counter. A retailer selling both ways usually needs both, connected at the product and the stock rather than merged: the same item, one stock position, two ways of buying it.

What is the difference between POS and retail ERP?

Scope. A POS owns the counter and the sale; a retail ERP is the umbrella term for running the whole retail business — stock, purchasing, suppliers, finance and often more — with the counter as one module among many. In practice most retailers do not buy an ERP, they accumulate one: a strong POS first, a stock system when a second outlet arrives, purchasing when suppliers become the bottleneck. Building the pieces separately and connecting them is usually cheaper and always easier to change than committing to one platform for everything on day one.

What is the difference between POS and accounting software?

A POS owns the transaction — what was sold, at what value, paid by what method, on which receipt. Accounting owns the books: the ledger, the treatment of that revenue, the returns and reconciliations that follow, and the statements and filings built on top. The POS is a source of truth for accounting, not a replacement for it, and the useful arrangement is a clean handover of transaction data rather than a retail system quietly growing a second set of accounts nobody audits.

Can barcode scanners or receipt printers connect to a custom POS?

Usually, and it is worth separating the two halves of the question. The system side is straightforward: items carry scannable identifiers and the counter screen can be built around scanning, searching or both. The hardware side depends entirely on the specific device — scanner, receipt printer, cash drawer or scale — and what its manufacturer and drivers support in the environment the till runs in. That gets checked against your actual equipment before it is scoped, because promising hardware compatibility in advance is how a retail rollout stalls a week before it opens.

Can a POS support different payment methods?

The sale records a tender method and a payment state, so cash, card, UPI, a split across two methods or a business’s own arrangement can all be represented. Whether the system also talks directly to a payment terminal is a separate question and it is answered by your provider, not by us — what their device exposes, what their integration allows and what it costs. Where a direct connection is possible it is scoped; where it is not, the counter records the payment that happened and everything downstream still works.

Can GST or tax rules be configured in a custom POS?

Tax fields and rates can be configured at the item and transaction level, shown correctly on the bill, and handled across outlets that are registered separately. That covers what most retailers mean when they ask. What it deliberately does not cover is tax compliance itself — filing, e-invoicing, statutory returns or any claim that the output is legally correct. Those belong with your accountant and your accounting system, and a retail system that pretends otherwise is doing its customer a disservice.

Custom POS or off-the-shelf POS software?

Off-the-shelf is the right answer more often than a software company usually admits. If your retail flow is ordinary — items, prices, a counter, a receipt — and your hardware is already supported, buying a mature product is faster, cheaper and better supported than anything built from scratch. Custom earns its cost when the selling process is genuinely specific, when existing systems must be kept and connected, when outlets differ in rules or commercial arrangement, or when a standard product would force you to change something that already works. The test is whether you would have to change how you trade to use the product.

Does every retailer need a custom POS?

No, and a single shop with a simple catalogue almost certainly does not. A mature retail product will serve that business better than a build. The picture changes when there are several outlets with rules that differ, when the catalogue behaves in a way standard products cannot express, when other systems have to be kept and connected, or when the retailer keeps working around their software instead of with it. The signal is not the size of the business — it is how much of the day is spent compensating for the till.

What determines the scope of a POS project?

Mainly how the catalogue behaves and how many systems have to agree about a sale. A flat item list, one price, one outlet and a self-contained till is a contained build. Variants and bundles, outlet or customer pricing, promotion and approval rules, several outlets with different arrangements, and connections to stock, online sales, customers or the books each add defined work. What rarely determines it is the length of a feature list — most retailers need a narrower system built properly around how they actually sell.

Who owns the system and data after a custom POS build?

You do — the system, the source code and the retail data inside it, including your catalogue, customers and transaction history. There is no licence to keep paying for the software itself, and nothing is withheld that would stop another team working on it later. Hosting, support and further development are separate arrangements you choose, not conditions of keeping what was built.
