Third-Party Integrations,Wired to Work
Short answer: A third-party integration connects your backend to an external service — a CRM, ERP, payment processor or any tool with an API — so data and actions flow between them automatically instead of being copied by hand. Done well, an integration keeps two systems in sync reliably, handles failures, and doesn't break when the other side changes. We build and maintain integrations to the CRM, payments, accounting and external APIs your product depends on, with the retries, webhooks and monitoring that keep them dependable.
Third-Party Integrations That Stay in Sync
A third-party integration is the plumbing between your product and someone else's — pushing a new customer into your CRM, charging a card through Stripe, syncing orders to an ERP, or pulling data from a partner's API. The goal is simple to state and hard to do well: the two systems should agree, automatically, without a person copying data between them. Every business tool your product touches is a potential integration, and they quietly become some of the most-used code you own.
The parts that decide whether an integration is reliable are error handling, data mapping and staying in sync. Real integrations must survive the other service being down, rate limits, and fields that don't line up cleanly between systems — so retries, idempotency, and a clear mapping between their data model and yours are what separate a demo from production. The usual failures are integrations that silently stop syncing, duplicate records from missing idempotency, and brittle code that breaks the moment the vendor changes their API.
We build integrations with retries, dead-letter handling and monitoring so a failed sync alerts someone instead of vanishing, and we use webhooks for real-time updates where the service supports them. Because the same team owns your backend, integrations are shaped around your actual data and workflows — not a generic connector you have to work around.
What we cover
What We Build in Third-Party Integrations
Payment & billing integrations
Stripe, PayPal and Square for one-off charges, subscriptions, invoices and webhooks.
ERP & accounting integrations
Sync orders, inventory and invoices with NetSuite, QuickBooks, SAP and similar systems.
Webhooks & event sync
Inbound and outbound webhooks for real-time updates, with signature checks and replay handling.
iPaaS & middleware
Zapier, Make or n8n flows for lighter connections, or custom middleware when logic gets real.
Custom API clients & SDKs
Robust clients for any REST, GraphQL or SOAP API, with auth, rate-limit handling and retries.
Services
Third-Party Integration Services
From a single connector to a synced ecosystem of tools — built to keep working when the other side hiccups.
Single integration build
Connect your product to one external service — payments, CRM or an API — end to end.
Multi-system sync
Keep several tools in agreement with reliable, conflict-aware two-way synchronization.
Payment integration
Add Stripe, PayPal or Square for checkout, subscriptions, refunds and webhook handling.
Webhook infrastructure
Build the endpoints and queues to receive, verify and process events from external services.
Legacy & EDI integration
Connect to older systems and EDI or SOAP partners with the adapters and mapping they require.
Integration monitoring & repair
Add alerting and retries to flaky integrations, or fix ones that keep silently breaking.
Tools & platforms
The Integration Stack We Build With
The exact toolset depends on your goals — these are the platforms we use most, and we work with whatever your team already relies on.
ERP & Accounting
Chosen per project — not a fixed menu. Have a preferred tool or platform? We’ll work with it.
Built to last
Secure, Accessible & Built to Last
We build on modern, well-supported frameworks with security and accessibility baked in — dependency hygiene, input validation, HTTPS and WCAG-minded UI — so your product is safe and usable from day one.
You own all the code and assets. Everything ships with documentation and a clean handover, so your team (or ours) can maintain and extend it without lock-in.

FAQ
Third-Party Integration questions
How much does a third-party integration cost?
A single, well-documented integration typically starts around $4,000, while syncing several systems two-way with monitoring can run $20,000 or more. Cost depends on how many services, whether sync is one- or two-way, and how cooperative each API is — use the estimator, then book a free call for a firm quote.
What is a third-party integration?
A third-party integration is code that connects your product to an external service's API — like a CRM, payment processor or ERP — so data and actions move between them automatically. Instead of staff copying records by hand, the systems stay in sync on their own.
How long does an integration take to build?
A straightforward integration to a well-documented API usually ships in 2–4 weeks; a multi-system, two-way sync or a legacy/EDI connection runs 5–10 weeks. Timelines depend heavily on the quality of the other service's API and how cleanly the data maps.
What happens when the other service goes down or changes its API?
We build integrations to expect that: retries with backoff, idempotency so nothing double-posts, dead-letter queues for failed events, and monitoring that alerts a human. When a vendor changes their API, versioned clients and tests catch the break before your data does.
Can you integrate with a service that has a poor or no public API?
Often, yes. We work with REST, GraphQL, SOAP and EDI, handle unusual auth schemes, and can build against partner or file-based feeds when there's no clean API. If a service truly can't be integrated safely, we'll tell you before you spend money on it.
Can you add integrations to our existing product?
Yes. Most integration work sits on top of an existing app — we add the connectors, webhooks and sync jobs your product needs without rebuilding it, and shape them around your current data model.
Should we use Zapier or a custom integration?
For simple, low-volume connections, an iPaaS tool like Zapier, Make or n8n is fast and cheap, and we'll set that up. When the logic, volume or reliability requirements grow, custom middleware is more robust and cheaper to run — we help you pick per case.
Do you build integrations for clients outside Houston?
Yes. We're based in Houston, TX and deliver integration work to clients nationwide and internationally — across 20+ years we've delivered 700+ projects for local and remote teams alike.
