For teams seeking a custom software partner in Istanbul

For teams seeking a custom software partner in Istanbul

Istanbul teams expect speed, deep integrations and multi-site coordination. Delivery succeeds when communication, written scope and measurable demos match the city’s pace. Aksiyon Soft is headquartered in Samsun only — no Istanbul branch or sales office. Official contact and discovery requests: contact. We deliver with Samsun-based engineering and planned Istanbul workshops and go-live support.

Fintech ops, e-commerce scale, agency-to-product transitions and holding structures are common. Payment services, marketplace integrations, high-traffic B2B portals and ops consoles appear frequently. Product owners in Istanbul share the same sprint calendar as our Samsun HQ team.

HQ in Samsun, hybrid with Istanbul stakeholders

Architecture, code review and sprint planning live in Samsun. We schedule discovery, design reviews and launch support in Istanbul. VPN, SSO and data residency are clarified in the first discovery hours — not the week before production.

Fintech panels need four-eyes approval and immutable audit logs. E-commerce programmes plan for peak traffic, stock sync and returns in the integration layer. Multi-office product teams need one backlog and one demo day — not a local branch label.

Middleware and system integration in Istanbul: ERP, e-invoicing and APIs

For fintech teams, e-commerce operations and multi-site holdings in Istanbul, integration is not a one-off project but infrastructure that runs all the time. An e-commerce company wants marketplace orders, stock sync, courier data, returns and e-invoices reconciled within minutes. A finance operations team has to keep transactions arriving from partner bank APIs consistent with reconciliation and audit reports.

Middleware is a shared layer between these systems rather than a web of point-to-point links. The ERP, e-invoicing provider, marketplaces, payment institutions, customer support consoles and, where useful, AI services talk through one versioned API contract, with data masking, access control and the audit trail applied in one place. We cover the design options in enterprise integration middleware architecture.

On campaign and sale days, webhook traffic multiplies and the same order event may arrive several times. Events therefore go onto a queue, failed calls are retried with increasing intervals and an idempotency key prevents duplicate orders or invoices. How to publish database changes and messages consistently is explained in our outbox pattern, idempotency and retry guide.

• Marketplace and stock: order, return and stock events synced with the ERP through the queue.
• Payments and reconciliation: bank and payment-institution records flowing into a daily reconciliation report.
• E-invoicing: high-volume submission, response tracking and reprocessing of failed documents.
• Observability: dashboards and alerts for latency, error rate and queue depth.

Because sandbox access to bank and payment-institution APIs usually takes time, the integration layer is first built against mock services and protected by contract tests. When real access arrives, only connection settings change, and Istanbul product owners see new features and stabilisation work in the same backlog.

We build this layer through our API and integration service, combining Samsun-based engineering with sessions for Istanbul stakeholders. For public-sector and industrial scenarios in the capital, see our Ankara enterprise software partner guide.

Get in touch

Contact for discovery. Transparent sprint rhythm from Samsun — no fake Istanbul office.

Integration and compliance in Istanbul programmes

Fintech and retail teams juggle PCI DSS, KVKK, internal audit and regulator reporting. Data minimisation, field-level masking and RBAC should be fixed in discovery — not during launch week. Bank and payment-provider sandboxes often take weeks to approve; start access requests early. Marketplace webhooks, return-reason codes and promotion rules belong in one versioned integration layer with realistic load tests before peak sales seasons.

Agency-born product companies often carry legacy shortcuts from client delivery. We align refactor sprints from Samsun with Istanbul product priorities so stabilisation and features share one backlog. Holdings that combine an Istanbul HQ with Anatolian plants need tenant or org-tree data partitioning documented as architecture, not afterthought.

Delivery, cost, adoption

Weekly written status for executives; definition of done includes tests and review. Staging runs end-to-end flows before go-live; rollback is rehearsed. After discovery choose fixed scope, T&M or a dedicated team — off-the-shelf vs custom helps make-or-buy. Hypercare then SLA maintenance with business metrics (conversion, ticket SLA, reconciliation errors) alongside technical dashboards. Training and short walkthrough videos improve adoption when product, support and analytics teams in Istanbul join early.

We do not claim an Istanbul street address — only Samsun HQ on contact. Value for Istanbul teams is sprint discipline, written scope and planned on-site reviews. See how to choose a software company and our Samsun HQ delivery model.
