Systems integration
Make the software you already pay for work as one system.
- Engagement
- Fixed-scope per integration, or bundled into a retainer
- Typical timeline
- 3–8 weeks depending on system count
- Starts at
- $8,500
Priced per integration once we've reviewed the APIs involved. Poorly documented legacy systems cost more and we say so up front.
Book a callYou're probably reading this because
If two or more of these describe your situation, a 30-minute call will be worth your time.
- The same customer record is entered by hand into three different systems.
- Your finance team reconciles two systems in a spreadsheet every month.
- A vendor says their API can do it and nobody internally can evaluate that claim.
- An integration exists, breaks silently, and you find out from a customer.
- You're changing platforms and years of data have to move without losing anything.
Concretely, what we deliver
Written as deliverables rather than activities, so you can tell whether you received them.
- 01
Integration map
Every system, what data it owns, where it duplicates another, and which one wins in a conflict. Most integration problems are really unresolved questions about which system is authoritative.
- 02
Pipelines that survive contact with reality
Built for the cases that break naive integrations: rate limits, partial failures, duplicate deliveries, schema changes, and the vendor's unannounced maintenance window. Idempotent, retried, and safe to replay.
- 03
Monitoring that pages a human
Every integration reports its own health. If a sync stops, someone is alerted with the failed records and a way to reprocess them. Silent failure is the default state of unmonitored integrations and it's the expensive one.
- 04
Internal APIs and middleware
A documented layer your other systems talk to, so replacing a vendor later means changing one adapter instead of six applications.
- 05
Data migrations with a rollback
Rehearsed against production-scale copies, reconciled record by record, executed with a tested path back. We migrate in windows you approve and prove the counts match before we cut over.
Our approach, and why
The reasoning matters more than the method. If you disagree with the reasoning, we should talk before you hire anyone.
Decide what's authoritative first
Before writing any code we establish which system owns each field. Skipping this is why integrations end up in loops where two platforms endlessly overwrite each other.
Assume every dependency will fail
Third-party APIs go down, change without notice, and lie about their rate limits. Everything we build queues, retries with backoff, and can be replayed from a durable log, so an outage becomes a delay rather than lost data.
Reconciliation, not faith
Every pipeline gets a periodic check that both sides still agree, with discrepancies reported. Integrations drift; the only way to know is to keep counting.
Documented for whoever comes next
Field mappings, transformation rules, credential rotation, and failure runbooks written down. Undocumented integrations are the most common form of key-person risk we find.
Technologies we use for this
- REST & GraphQL APIs
- Webhooks
- Zoho
- Salesforce
- HubSpot
- QuickBooks
- Stripe
- SendGrid / Twilio
- RabbitMQ / SQS
- Airbyte
- Laravel / Python workers
- PostgreSQL
Selected per project against your team's existing skills and hiring market, not against what's fashionable. If your system runs on something not listed, ask.
What changes for you
- Data entered once and correct everywhere it appears.
- Month-end reconciliation stops being a manual exercise.
- Broken syncs surface within minutes instead of at a customer's expense.
- Switching a vendor becomes a project rather than a catastrophe.
What people ask about systems integration
There's usually a path: a database replica, scheduled file exchange, or a supported export. Screen-scraping and browser automation exist as last resorts, but we'll be clear that they're fragile and priced with ongoing maintenance in mind.
On a support retainer, we monitor for deprecation notices and handle the migration. On fixed-scope work, we hand over documentation and you can bring us back as needed. We'll say which we recommend for your situation.
Often, yes. The hard part is rarely extraction. It's establishing that the new system holds the same truth as the old one. We build that reconciliation before cutting anything over.
Often combined with
Custom Software Development
Applications built for how your business actually works: the workflows no off-the-shelf product will ever match.
AI & Intelligent Automation
LLM features, document processing, and automation that connect to your real data and hold up under production load.
Support & Modernization
We take over existing systems (including ones whose original developers are long gone), stabilize them, and modernize them incrementally.
Let's talk about your systems integration project
Thirty minutes with an engineer who can scope it. You'll leave with a view on approach, a budget range, and an honest answer about whether we're the right firm, including when we aren't.
