System Integration

Connect Shopify, Etsy, CRMs, ERPs, accounting, shipping tools, spreadsheets, and internal databases so data flows reliably.

When your tools don’t talk to each other

Orders live in one system, inventory in another, and accounting in a third. Someone exports a CSV every week to keep them roughly in sync. Updates lag, customers get wrong information, and you’ve outgrown the manual bridges holding it together.

Reliable integration is most of what I do in my day job, at scale — sync jobs that run millions of times a day and can’t quietly drop data. The same discipline goes into connecting the handful of tools your business runs on.

What’s involved

Design the integration around how the business actually operates
Build reliable sync jobs, webhooks, and APIs between your existing platforms
Handle retries, error alerts, and idempotency so a failure never corrupts your data
Document the data flows so the next person isn’t guessing

What you’ll need from your side

Admin access to the systems being connected (or someone who can grant it)
A clear description of what “correct” looks like when the data lines up
Examples of where things currently go wrong

What you get

One source of truth for orders, customers, or inventory
Manual export and import work removed from the weekly routine
Integrations that survive API changes and vendor updates, with alerts when something needs attention

Integration projects start from CA$5,000 and are scoped precisely after a Business Systems Audit.

Where to start

A Business Systems Audit (CA$1,500) maps your tools and pain points and returns a written plan for connecting them. If you’d rather talk it through first, a free Business Systems Review is a good opening step.

Frequently asked questions

Do you build from scratch or fix existing software?

Both, but I usually start by fixing and stabilizing what you already have. A full rebuild is only recommended when the existing system genuinely cannot support the business.

Can you work with our current tools?

Yes. Most engagements connect tools you already use — Shopify, Etsy, CRMs, spreadsheets, Airtable, Zapier, Make, accounting software, shipping tools, and custom APIs.

Can you work with our agency on client projects?

Yes. Agencies use me as a white-label or named technical partner for backend systems, integrations, automation, and infrastructure their team does not build in-house.

Do you build websites?

Yes — for companies of any size. That includes new sites, redesigns, ecommerce storefronts, and sites connected to CRMs, booking tools, and internal systems. I also fix broken or outdated websites when a rebuild is not the right first step.

Do you work hourly or fixed-price?

Audits and fix sprints are usually fixed-price after a short scoping conversation. Ongoing support is monthly. Hourly is available for small advisory work when it makes sense.

Can you help with AI tools and automations?

Yes — especially when an AI tool worked in a demo but fails in real use. I focus on making workflows reliable, auditable, and maintainable.

Can you support the system after launch?

Yes. Ongoing Website & Systems Support covers fixes, updates, small improvements, and adapting to vendor or API changes as your business evolves.

Do you work with local businesses and remotely?

Both. Based in Durham Region, Ontario. Most work is remote with clear documentation. On-site discovery is available when it helps.

What does a free website review include?

A practical look at your mobile experience, local search basics, contact forms, tracking, and obvious places where inquiries get lost — with clear next steps. Free for local businesses in Durham Region.

Do you only do websites, or software too?

Both. Many local clients start with a website or contact-flow fix. Growing teams and agencies often need software rescue, automation, and integrations — same partner, different entry point.

Who is Blachn.io Software Services for?

Businesses that want one developer for their website, software, automation, and support — instead of hiring a full engineering team or juggling multiple freelancers.
