01Where operations break
Where retail and D2C operations break
Every new channel adds revenue and a new copy of the stock count. Without a system that ties them together, the team becomes the integration layer.
Stock counts that disagree
Each marketplace and the store keep their own inventory, updated by hand. Reports are inaccurate, and orders are accepted for stock already sold elsewhere.
Stock-outs and overstock
Without reliable low-stock signals, products are under-ordered and over-ordered, and revenue is lost when supply falls short of demand.
Billing on paper
Handwritten bills make tax compliance difficult and leave the business without a clean sales record.
B2B balances from receipts
Outstanding amounts for trade customers are calculated from paper receipts, and the figures are rarely right.
Custom orders in chat threads
Enquiries, requirements and customizations are tracked in messaging apps and notes, separate from the purchase they lead to.
When every channel keeps its own count, someone on your team is the integration layer, and people don't scale.
02The systems landscape
The retail systems landscape, and where it typically breaks
Most retailers we speak with run several of these in parallel. The audit decides which one holds the stock record and how the others report into it.
| System | What it holds | Where it typically breaks |
|---|---|---|
| Marketplaces (Amazon, Flipkart, Meesho and others) | Listings, orders, returns | Each marketplace sells against its own stock number, updated by hand. |
| Own e-commerce store | Retail, bulk and custom orders | Custom requirements captured outside the order, in messages. |
| Counter billing and point of sale | Walk-in and B2B sales | Paper bills or a standalone tool that doesn't update stock. |
| Inventory and warehouse | Stock, units of measure, locations | Spreadsheets that can't convert boxes to pieces or show low stock in time. |
| Accounting and tax | Invoices, returns, compliance | Sales re-entered from bills, with gaps between the two. |
| B2B accounts | Credit, outstanding balances | Calculated from receipts instead of from the sales record. |
03Reference architecture
Reference architecture: a central inventory every channel reports into
The pattern we use holds stock in one central inventory. Marketplaces, the online store and counter billing don't keep their own counts; they report each sale into the central record, which reduces stock once and publishes the new available quantity back to every channel.
Around that record sit the functions that depend on accurate stock: low-stock alerts before shelves run empty, tax-ready billing and a real-time management dashboard that stakeholders can open from anywhere.
Design decisions we make in retail and D2C
-
Deduct stock exactly once
Marketplaces retry, report late and send duplicates. Each order carries an identifier, so stock is reduced once however many times it's reported. This is idempotent processing.
-
Reconcile, don't assume
A scheduled reconciliation compares the central record with each channel and flags differences, so drift is caught before it becomes an oversold order.
-
Model real units
Stock is held in the units the business actually uses: a box, a bundle, a meter. It converts automatically at billing, so counts stay true.
Key design decisionStock is held in one place and the channels report into it, rather than each channel keeping its own count. The business gets one number to trust and a single point to control, at the cost of depending on each marketplace's integration, which is why we design every channel connection to be monitored.

05Proof
Proof: three retail engagements in development
These engagements are active. Each page documents the system before, the risk and the architecture, and names the measures that will be reported. We don't publish projections, so there are no outcome numbers here yet.

How we de-risk change in retail and D2C
A retailer can't stop selling while its systems change. These are the risks we plan around.
RiskOverselling during cutover
Channels move onto the central inventory one at a time, with buffer stock held back until counts reconcile.
RiskMarketplace dependencies
Each marketplace integration is monitored, and failed updates are retried and flagged instead of silently dropped.
RiskContinuity at the counter
The billing application is designed for speed at the counter, and paper billing remains available until the new system is proven.
RiskOpening balances
Stock and B2B balances are counted, verified and loaded before go-live, so the new system starts from a trusted position.
07Is this your situation?
Is your organization facing the same pattern?
- You sell on more than one marketplace or channel, and each keeps its own stock count.
- Orders are sometimes accepted for stock already sold elsewhere.
- Bills are handwritten, or billing doesn't update inventory automatically.
- B2B outstanding balances are calculated from receipts.
- Custom or bulk orders are managed in messaging apps.
If these describe your business, an integration assessment will map every channel, where stock counts diverge and what one central inventory would take.
08Questions
Frequently asked questions
How do you keep inventory in sync across Amazon, Flipkart, Meesho and our own store?
By keeping stock in one central inventory and having every channel report into it. Each order reduces central stock exactly once, even if a marketplace retries or reports late, and the available quantity is published back to every channel. A scheduled reconciliation catches any drift before it becomes an oversold order.
How do we move from paper billing to a system without interrupting sales at the counter?
Load and verify opening stock and B2B balances first, then run the billing application alongside paper until the records match. The application is built for counter speed, with customizable stock units so staff bill in the units customers actually buy.
Can custom and made-to-order products be sold through e-commerce?
Yes. Custom requirements are captured as part of the order, so they are recorded, tracked and fulfilled with the purchase rather than in a message thread. The Pirruntha Silks platform takes customized, retail and bulk orders from customers anywhere in Europe.
Why don't the retail case studies show outcome numbers?
All three retail engagements are still in development. We publish measured results, not projections, so each case study names the measures that will be reported once they can be compared with the current baseline.
How does an engagement start?
With an integration assessment: an enterprise architect maps every channel you sell through, where stock and order data diverge, and what connecting them to one central inventory would involve, before any build is estimated.
