API Integrations and Software Connectivity
API integrations and software connectivity from €900 with a 1-4 week timeline. Saitami builds reliable connections between the systems you already use: ERP/CRM, e-commerce stores, accounting software, couriers, payment providers, Google Sheets, email/SMS/Viber automations, and third-party API platforms. The goal is automatic data flow without manual copying, lost orders, or departmental chaos. You get clear architecture, logs, retry mechanisms, code ownership, and API documentation.
What You Get
- Automatic data exchange
Orders, invoices, customers, stock levels, payments, and statuses sync between systems without manual entry.
- Fewer errors and lost orders
We add validations, logs, retry mechanisms, and failure alerts so you do not rely on copying between Excel, ERP, and website.
- Integrations around your workflow
We do not force a template. We map the real process: who creates the data, who approves it, where it must go, and when.
- API and code ownership
You receive documentation, code access, and a clear technical diagram instead of a black box and vendor lock-in.
- Ready to scale
We build integrations so you can later add a new warehouse, courier, sales channel, or ERP/CRM module.

What do API integrations solve?
Many businesses already have a website, ERP, CRM, warehouse, accounting, couriers, payments, and spreadsheets, but the systems do not talk to each other. The result is manual copying, delayed orders, different data in different departments, and unreliable reporting.
Saitami builds integrations that turn separate tools into one working process. When a customer places an order, data can automatically reach ERP/CRM, accounting, courier, payment, Google Sheet reporting, and email/SMS/Viber notification.
Typical integrations we build
ERP/CRM: customers, deals, offers, invoices, inventory, tasks, statuses, and reports.
E-commerce: WooCommerce, Shopify, custom stores, products, orders, payments, stock levels, promo codes, and returns.
Accounting and invoicing: automatic invoice creation, payments, bank statements, export to accounting software, and tax-authority links when the workflow requires it.
Couriers and logistics: Econt, Speedy, DHL, waybills, shipping prices, statuses, tracking, and customer notifications.
Automations: Google Sheets, email, SMS, Viber, internal alerts, dashboards, BI reports, and custom webhooks.
Price, timeline, and how we start
Starting price: from €900 for a small API integration with one system and a clearly documented workflow. Standard project: €1,500-€5,000 for two or more systems, test environment, logs, retry mechanisms, and documentation. More complex integration platforms, middleware, and multi-step workflows are estimated after a technical specification.
We start with a 30-60 minute call and a system map: what data moves, where it is created, who uses it, which errors are critical, and what must happen when synchronization fails. Then we provide concrete scope, price, and milestones.
Why API ownership matters
An integration should not be a black box. If tomorrow you change ERP, add a new courier, or open a new sales channel, you should be able to extend without starting from scratch. That is why we document endpoints, authentication, retry logic, data formats, API limits, and each system’s responsibilities.
You receive your own code and technical documentation. This reduces vendor lock-in, makes support easier, and keeps the business less dependent on one vendor.

Real scenario testing
We test order, invoice, payment, delivery, return, status change, and invalid data before production.
Launch, monitoring, and documentation
We launch in stages, monitor logs, and hand over documentation for support and future development.
Frequently Asked Questions
A small integration starts from €900. Typical ERP/CRM, e-commerce, courier, or payment projects are €1,500-€5,000. Price depends on the number of systems, API documentation quality, middleware needs, and test scenarios.
ERP/CRM systems, WooCommerce, Shopify, custom stores, accounting software, banks, Stripe, ePay, EasyPay, couriers such as Econt/Speedy/DHL, Google Sheets, email platforms, SMS/Viber providers, and external REST/GraphQL APIs.
Often yes. If there is no API, we check CSV/XML exchange, database access, webhook via middleware, automated import/export, or custom connector options. If the risk is high, we say it upfront.
Yes. With custom development you receive code ownership, API documentation, access instructions, and flow diagrams. We do not lock you into a platform you cannot replace.
A clear single integration usually takes 1-2 weeks. Projects with multiple systems, data migration, or complex statuses take 3-8 weeks. We work in stages so there is visible progress early.
