Inventory mismatch across channels
Stock is updated at different times on the website, marketplaces and stores. Overselling leads to cancellations and marketplace penalties, while slow updates hide stock that could have been sold.
INDUSTRIES / RETAIL
Software for D2C Brands, Multi-Store Retailers and Distributors
Retail now often means selling the same product through a website, marketplaces, physical stores and distributors, all drawing on the same limited stock. RDS Innovations builds and connects the systems that keep this manageable: product catalogs, online stores, marketplace listings, inventory, orders, returns and loyalty.
THE SECTOR
How retail businesses operate.
A D2C brand may start with a single online store, then add marketplaces such as Amazon or Flipkart, quick-commerce listings, a few retail counters and wholesale orders. Each channel wants product data in its own format, from images and size charts to HSN codes and marketplace-specific attributes. Prices and offers vary by channel, and so do fees, payout cycles and return policies.
Multi-store retailers face the same problem from the other side. Stock sits in several stores and a warehouse, billing happens on POS terminals, and customers expect to order online and collect in store, or return an online order at a branch. Distributors and wholesalers handle credit limits, beat plans for field sales reps and bulk orders on price lists that differ by customer.
Software matters because stock and customer data must stay consistent across all of these channels. If inventory updates lag, the business oversells on one channel while stock sits idle for another. If purchases are split across systems, loyalty and repeat marketing become guesswork. The right setup is often a mix of ready-made platforms and custom connections rather than one system that tries to do everything.
CHALLENGES
Where things slip today.
Catalog upkeep
Every new product or variant must be created with images, descriptions, attributes and tax details for several channels. Manual uploads are slow and easy to get wrong.
Returns and reverse logistics
Returns arrive from couriers, marketplaces and stores, each under different rules. Condition checks, refunds and restocking are often tracked by hand.
Fragmented customer data
Website shoppers, walk-in buyers and marketplace customers sit in separate systems, so it is hard to recognize repeat customers or run one loyalty program.
Order processing at sale-time volume
During sales and festive periods, picking, packing, invoicing and courier booking order by order becomes the bottleneck.
Unclear margin by channel
Marketplace commissions, shipping, payment fees and returns make true profit per channel hard to see without consolidated reporting.
KEY WORKFLOWS
Workflows software can support.
- 01
Central product catalog
Products and variants are created once with images, attributes, pricing and tax data, then mapped and published to the website and each marketplace in the format it requires.
- 02
Multi-channel stock sync
Stock from the warehouse and stores is combined into a sellable quantity, with buffer rules per channel. Changes are pushed to each channel as orders, receipts and adjustments happen.
- 03
Order routing and fulfillment
Orders from every channel land in one queue. The system picks a fulfillment location based on stock and distance, creates pick lists, invoices and shipping labels, and books couriers through an aggregator.
- 04
Returns and exchanges
Customers raise a return or exchange from a self-service page. The warehouse records the item's condition on receipt, and the system triggers a refund, store credit or replacement shipment and updates stock.
- 05
Loyalty across online and store
Purchases from the website and stores link to one customer profile by phone number. Points, tiers and personal offers apply at online checkout and at the store counter.
- 06
Distributor and B2B ordering
Distributors and retailers place orders from a portal or app using their own price lists, minimum quantities and credit limits, and field reps can place orders for them during visits.
POSSIBLE DIGITAL SOLUTIONS
What we could build with you.
Options to consider, not a fixed package. The right scope depends on your size, processes and existing tools.
Platform-based or custom online store
A storefront on a platform such as Shopify or WooCommerce, or a custom Next.js store when performance, design or unusual product logic call for it.
Order and inventory hub
A central system that pulls orders and stock from every channel, handles fulfillment and returns, and sends updates back, sitting between your sales channels and your accounting software.
Marketplace listing tools
Bulk listing and update tools that turn your central catalog into marketplace-ready files or API updates, reducing repetitive uploads.
Loyalty and customer app
A program or mobile app for points, rewards, referrals and order tracking that works both online and in stores.
B2B ordering portal
A portal or app for distributors and retailers with customer-specific pricing, trade schemes, order history and outstanding balances.
Sales and margin dashboards
Reports that combine sales, fees, returns and stock by channel, product and location to show which products and channels actually make money.
Typical software requirements
- Product information model with variants, bundles, barcodes and HSN codes
- Location-aware stock with reserved, available and in-transit quantities
- Category and attribute mapping for each marketplace
- Bulk actions for order processing during peak periods
- One customer profile across channels, with consent for marketing messages
- GST invoicing logic confirmed with the client's accountant
- Audit trail for stock adjustments and price changes
Common integrations
E-commerce platforms such as Shopify or WooCommerceMarketplace seller APIs, subject to each marketplace's access approvalShipping aggregators and courier APIs for labels, tracking and return pickupsStore POS systems, depending on the API or export options they offerPayment gateways such as Razorpay or Stripe, plus cash-on-delivery reconciliationAccounting software such as Tally or Zoho Books for sales, returns and marketplace settlementsWhatsApp Business API, email and SMS for order updates and abandoned cart remindersGoogle Analytics 4, Google Tag Manager and Meta Ads for conversion tracking
Considerations
- POS integration is often the hardest part. Some POS systems offer modern APIs, while others only export files at intervals, which affects how quickly store stock shows online. We review the POS before promising real-time sync.
- Marketplaces change their APIs, fees and listing rules regularly, so marketplace integrations need ongoing maintenance.
- Customer contact data used for loyalty and marketing should be collected with consent and handled in line with the Digital Personal Data Protection Act, 2023, with legal advisers reviewing the approach.
- Full card details should never be stored in the store's own database; the payment gateway handles them.
- A custom store is not always the right first step. Many brands start on a platform and add custom pieces as specific needs appear.
FAQ
Retail software questions.
Should we build a custom store or use Shopify?
If your catalog and checkout are fairly standard, a platform like Shopify or WooCommerce is usually quicker and cheaper to start with. A custom build is worth considering when you need unusual product configuration, B2B pricing, deep integrations or full control over performance and design. Many businesses run a platform with custom apps around it.
Can you keep stock in sync between our website, Amazon and our stores?
Yes, provided each channel offers an API or a regular data feed. A central inventory hub calculates sellable stock and updates each channel, with buffer rules to reduce overselling during busy periods.
Can store staff use the same loyalty program as the website?
Yes. Customers can be identified by phone number at the counter, with points and offers shared between store and online purchases. Exactly how this works at checkout depends on what your POS allows.
How are marketplace returns handled?
Marketplace returns can be pulled into the same returns queue as website returns, with condition checks recorded at the warehouse. Stock and refund status are then updated according to each marketplace's process.
Can distributors place orders online?
A B2B portal or app can show each distributor its own prices, schemes and credit limit. Their orders then flow into the same order and inventory system as every other channel.
