Online and store information drift apart.
Define the authoritative sources for stock, price and customer records, then build connections with clear update and exception behavior.
Retail software that connects the whole journey.
Bring stores, digital channels and business systems together, with practical experience in retail, marketplaces and omnichannel operations.
Discuss your next projectRetail software connects what a customer sees with the information and processes behind a purchase. A product, price, order or return may move between online, in-store and back-office systems. A useful digital experience depends on those connections being understandable and consistent.
Retter builds customer applications, commerce platforms and internal tools, and modernizes the systems already in place. Our retail experience helps shape the details, from the weekly release cadence and audit-driven backoffice work we run for Gratis to the hybrid on-premises and cloud backend behind Unifree’s duty-free limits. A new build or an iteration can start from a simple brief, whether the need is a full platform or one operational improvement.
The details that shape the build.
A return affects several systems at once.
Map how order status, payments, inventory and rewards change so teams can follow the transaction across channels.
Marketplace sellers need visibility and guidance.
Build onboarding, listing approval and operational tools around the marketplace model, with explicit responsibilities and permissions.
Build around your retail model.
A retailer with stores, a direct-to-consumer brand and a marketplace may share a checkout pattern but have different operating needs. We begin with channels, users and the order lifecycle, then identify how catalog, payment, fulfillment and customer-service systems interact.
The first release might improve an account experience, expose loyalty in a new channel, connect order information or give staff a better tool. A larger commerce build can follow the same approach in stages. The scope is driven by the business problem and the systems already working well.
Modernize without losing the operational detail.
Changes to commerce affect more than the storefront. Customer identity, promotions, consent, stock and returns each have owners and rules. Retter works with those teams to agree how information moves and what a successful change looks like before rollout.
AI can support product discovery, staff assistance or reporting when the underlying information is suitable. We define what it can access, which changes it can propose and when a person must review. The result should make work easier while remaining traceable to the data and decisions behind it.

Questions from
shops & online stores teams.
Can Retter connect online and in-store experiences?
Yes. The integration scope depends on the available POS, commerce, customer and inventory interfaces. We establish data ownership and transaction flows with the teams responsible for each system.
Do you build marketplaces as well as stores?
Yes. Seller onboarding, product approval, order workflows and supporting tools can be part of a marketplace engagement. We scope them around the commercial and operating model.
Do we have to rebuild our storefront?
No. An integration, staff application or focused workflow may address the need. We assess the existing platform and agree whether extending or replacing a component is appropriate.
