Send each record where it belongs
An event in one system triggers a write in the next one, with every field mapped to its counterpart. The sales team gets the lead, marketing gets the contact.
Your marketplace, accounting, CRM and login provider each hold part of the picture. We connect them so an order, a lead or an invoice is entered once and shows up everywhere it is needed. Then we automate the routine steps around it.


Most projects start with one of these and grow into the next. Knowing which one you need keeps the first phase small and the estimate honest.
An event in one system triggers a write in the next one, with every field mapped to its counterpart. The sales team gets the lead, marketing gets the contact.
Scheduled or change-driven sync jobs that pull from one side, update the other and keep a record of each run.
Workflows that place supplier orders, watch for tracking numbers, update inventory and charge clients at the right stage.
Grouped by what they do for the business. Every system on this list is linked to the project where we integrated it.
Order, stock and product data moving between your platform and the stores and suppliers you sell through.
Invoices, vendors and purchase orders that reach the books without a second round of typing.
Leads and contacts that land in the sales and email tools your teams already work in.
One login across sites, apps and back offices, managed by the identity provider you already trust.
Content and records imported from the APIs that own them, so nobody maintains a second copy.
Meetings, notifications and shipments handled by the services built for them, triggered from your platform.
Peregrine Ship runs a dropshipping and fulfillment platform out of Hong Kong. Sourcing managers used to buy stock from Chinese suppliers by hand for every order. From June 2024 to July 2025 OSKI worked across the platform’s front end, back end and API integrations, with a new automated sourcing step at the center.

“They maintained reliability without needing constant oversight, which made the collaboration efficient.”
Aspect, a print workshop in Zhytomyr, sells personalized mugs, shirts and canvases on Amazon in the US, UK and EU. Staff used to download each buyer’s artwork by hand and retype orders into their own tracking.
We connected the workshop to Amazon through SP-API. Orders and stock now sync every 15 minutes. A personalized order opens a print job on the right production line, with the artwork and ship-by date attached. Files under 300 dpi are held back, and the buyer is asked for a better one automatically.
An integration that works on launch day is easy. The hard part is month six, when an API times out at night. These are the safeguards we have put into client projects.
Failed requests are retried, and the result of every import is stored. A gap in the data shows up in a report instead of in a customer complaint.
Each import records what it fetched, what it changed and how it ended. Admins get a completion report, or an error email with the logs attached.
Sync jobs compare before they write. They touch the fields that changed and leave alone the ones your editors are allowed to override.
Duplicate SKUs, missing attributes and low-resolution files are flagged before they reach a store or a printer, not after.
Sync runs outside the user’s request, in Hangfire jobs or behind AWS SQS and Azure Service Bus queues, so a slow API does not freeze a screen.
Health checks and dashboards in Application Insights or Datadog show which connection is slow or failing, before someone has to ask.
Connected systems make it possible to hand whole routines to software: buying stock per order, routing jobs to production, billing at the right stage, reordering supplies. People keep the decisions. The system does the clicking.
When the work needs judgment rather than rules, such as reading customer messages or sorting requests, see our AI development service. When the systems themselves need replacing, see ERP development.
excess inventory stored at Peregrine Ship. Stock is sourced from suppliers for each order, so nothing sits in the warehouse waiting for a buyer. Read the case
Most integration bugs are disagreements nobody wrote down: which system wins, what counts as a duplicate, who hears about a failure. We settle those with you before the first sync runs.
We trace one record from start to finish: where it is created, who retypes it, which system should own it and what goes wrong today.
Authentication, rate limits, sandbox access, webhooks and the fields each side actually exposes. Surprises found here cost far less than surprises found in production.
Field mapping, which side wins on conflict, what happens to duplicates and who gets notified when a run fails. You sign off before we build.
The integration runs against a copy or a sandbox first. We compare counts and spot-check records with the people who use them.
Logs, run history and alerts are switched on from day one. We support the integration and adjust it when one of the connected systems changes.
Marketplace, accounting, CRM and content integrations for e-commerce, logistics, real estate, legal services and manufacturing.

A sourcing step that buys from 1688 suppliers for each order, tracks the shipment and bills clients only when each stage is complete.

A platform that pulls orders from 7 Amazon marketplaces, turns personalized orders into print jobs and shows the real margin on every product.

Faster, safer bulk imports to WooCommerce for ProdUp, plus a data quality dashboard and multi-language product editing.

A service and DLL pair that pulls property data from a GraphQL API into any Umbraco site, maps it by configuration and imports it in parallel.

Ongoing Umbraco work for Fairway Divorce: form workflows that deliver leads to Salesforce and Mailchimp, reusable components and steady support.

A custom ERP that brings inventory, order processing, purchasing and reporting together and keeps vendor data in sync with QuickBooks.
Quotes from verified Clutch reviews by clients whose projects included integrations and production systems.
They maintained reliability without needing constant oversight, which made the collaboration efficient.

What stood out most was their commitment to delivering a functional and reliable solution, no matter the challenges.
They're highly knowledgeable and responsive.
NetSuite integrates through REST or SOAP web services, RESTlets, SuiteScript, CSV import, marketplace connectors and iPaaS. We compare them by fit, limits and price, list where syncs break and show what a custom integration costs.
Shopify connects to NetSuite through Oracle's NetSuite Connector, Celigo's integration app, other apps or a custom build. We compare what each syncs and costs, list the failure points (variants, tax, discounts, refunds, payouts) and price a custom build.
The best CRM for events depends on whether you sell services to one client or run events for thousands of attendees. We compare six options for planners, venues and conference organizers by how they handle clients, attendees, sponsors and integrations.

We have shipped integrations with Amazon SP-API, the 1688 marketplace, WooCommerce, QuickBooks, Salesforce, HubSpot, Mailchimp, Oracle Eloqua, Okta, Auth0, Azure AD B2C, Moodle, Zoom, SendGrid, Twilio and GraphQL data feeds. Each one is linked to a case study on this page.
If a ready-made connector covers your flow and the volume is small, start there. It is cheaper. A custom integration makes sense when you need your own mapping rules, high volumes, money calculations, two-way sync, or a full history of what moved and when. We will tell you which one fits after we see the flow.
The integration retries, records the failure and tells someone. Depending on the project that means stored import results, a run history, an error email with logs, or alerts in a monitoring tool such as Application Insights or Datadog. Nothing is supposed to fail silently.
Often, yes. For the 1688 marketplace we combined its API with TMApi, a third-party service, to map products to suppliers. When there is no API, a validated file import is an option: on the EM2 event platform we built an Excel import that produces a line-by-line validation report.
It depends on the number of systems, the quality of their APIs and how much logic sits between them. A single form-to-CRM flow is a much smaller job than a two-way accounting sync. After we review both APIs and agree the mapping rules, you get a fixed estimate for the work.
Yes. For ProdUp we sped up and hardened existing WooCommerce imports with parallel tasks and retry logic. For One Motion ERP we maintain and extend a two-way QuickBooks sync that runs in production every day.
You do. The code, credentials and infrastructure live in your accounts, with full IP assignment in the contract. There are no per-connection or per-record fees to OSKI.
A spec, a Figma file or three paragraphs is enough to start.
