Web development for Chennai businesses
Web Development Company in Chennai
Keep your website and back office in step.
Manufacturers, distributors and retailers often hold stock, prices and orders in back-office systems that the website cannot see. Tangensys connects them, so the website shows accurate information and orders flow back automatically. We work with Chennai businesses remotely from Noida.

Who we help
Your website should know what your back office knows.
When stock levels, prices or order status live only in internal systems, the website shows outdated information and staff re-key orders. We connect the two through APIs, exports or middleware.
Manufacturers
Product data and availability from ERP.
Distributors
Orders and stock synchronised.
Retailers
Online and in-store inventory aligned.
Common problems
Is your website out of step with your systems?
Prices differ between systems
We sync from one source.
Stock shown online is wrong
We connect inventory.
Orders are re-keyed
We pass them back automatically.
Syncs fail without notice
We add alerts.
A practical starting plan
Keep stock, price and order information consistent
An integration can create operational confusion when several tools appear to own the same product or order information. This is an illustrative situation, not a claimed client project.
Choose the source of truth
Define ownership for stock, price and order states. Confirm identifiers and update timing, especially where staff also make manual changes.
Test reconciliation cases
Check repeated requests, conflicts and partial failures with approved data. Compare what the customer sees with the stored operational record rather than accepting a successful sync message alone.
Assign monitoring ownership
Record alerts, recovery and manual reconciliation steps. Provider access and limits are reviewed before live deployment; ongoing monitoring and support commitments follow the agreed scope.
Services
What web development can include
Scope and milestones
Describe the user roles, workflows and sign-off checks before selecting a build approach. Identify the first useful release and the features that can wait. Each milestone has an inspectable output and a named approver. The estimate depends on the real code, data, integrations and operating requirements; unfamiliar inherited systems need review before a reliable implementation scope can be agreed.
Custom development
Build the agreed feature in the context of your existing system or the chosen architecture. Keep source ownership, development access and release responsibilities clear. A completed feature includes its expected behaviour and relevant error cases, not only the happy-path screen. Larger engineering requirements are proposed against confirmed delivery capability or an agreed specialist partner.
Integrations
Map the information each system supplies or receives, its identifiers and the source of truth. Review permissions, duplicate prevention, failure handling and reconciliation before connecting live data. A successful API response alone does not confirm that the business workflow is correct. Provider limits, licences and unsupported interfaces are dependencies to resolve in the scope.
Staging and testing
Use representative approved data in a safe review environment. Check user permissions, validation, expected workflows and relevant failure cases before release. The sign-off note identifies what passed and what still needs attention. A staging environment should not expose confidential live records or send real customer messages unintentionally; production rollout follows the agreed release authority.
Security and performance
Review the access controls, dependency state and practical performance needs of the agreed feature. Secrets belong in appropriate configuration, with permissions limited to actual responsibilities. Record backup and recovery expectations alongside operating checks. Security work has a defined scope; a limited project review is not a guarantee that every risk in a system has been removed.
Maintenance and support
Identify who monitors the application, maintains dependencies and handles incidents after handover. Documentation should cover access, configuration, release and recovery for the work delivered. Ongoing support, service hours and response commitments are agreed separately. Keeping that boundary explicit makes future changes easier to commission and prevents maintenance assumptions being mistaken for a contractual service level.
Define the sign-off checks before comparing estimates
Development cost depends on the actual code, workflow, data and operating requirements. Integration permissions, provider limits, migration and testing can change the work substantially. Review access and dependencies before assuming a similar-looking screen means two projects have the same scope.
Share the current system, intended user task and known problems. A first technical review can establish what needs deeper investigation; implementation and continuing support are separately quoted. Larger engineering requirements depend on confirmed capability or an agreed delivery partner. Ask what will be tested, who approves release and what documentation the operational team receives.

Can updates be guaranteed instantly?
Timing depends on provider interfaces and the agreed architecture. Define acceptable behavior and failure handling rather than promising instant synchronisation without reviewing the systems.
What happens if two systems change the same value?
The design needs ownership and conflict rules. Test representative cases and document which value prevails or requires review, so staff can resolve discrepancies consistently.
