API Design and System Integration

Custom API integration and system integration services that make your software talk to each other.

The Hidden Cost of Disconnected Software

Most businesses are running on a stack of tools that do not talk to each other. A sale closes in the CRM, which means someone has to enter it into the accounting system. A ticket gets created in support, which means someone has to copy it into the project tracker. Every manual handoff is a place where things get missed, entered wrong, or forgotten entirely.

We can integrate solutions so that data and processes flow without a human in the middle.

What Custom Integration Actually Looks Like

Double A Solution

System-to-System Integrations

Clean connections between your CRM, ERP, accounting, support, and marketing tools. Data flows automatically in every direction so nothing gets re-entered and nothing falls through the cracks.

Double A Solution

Custom API Development

Custom APIs that let your software share data with customers, partners, or your own mobile and web products. Documented, authenticated, and built for real production traffic.

Double A Solution

Real-Time Data Sync Pipelines

Live sync between the tools your business runs on so every system stays current. Change a record in one place, watch it update everywhere else within seconds.

Double A Solution

Webhook-Based Automations

Trigger actions across your stack the moment something happens. A new customer in one tool can create records, send notifications, and update reports in every other tool automatically.

Double A Solution

Legacy System Migration

Move data out of aging systems and into modern platforms without losing history. We handle the mapping, cleanup, and validation so the new system starts on solid ground.

Double A Solution

Monitoring and Failure Handling

Every integration we build comes with monitoring, retry logic, and alerting. When something breaks upstream, you find out right away instead of weeks later from a customer complaint.

Security, Authentication, and Rate Limits

Integration work has to handle the ugly parts of real-world systems, not just the happy path. We build for the failure cases from day one. That means OAuth 2.0, API keys, and JWT tokens stored and rotated securely. Rate limiting with exponential backoff so temporary failures do not become permanent ones. Error tracking and alerts for failures that actually matter. And data validation at every boundary so bad data from one system cannot bring down another.

How We Connect Two Systems
That Were Not Built to Talk

Every integration project moves through the same five stages.

Map the Systems

We start by learning every tool involved and what data needs to move between them. Sometimes an integration already exists that nobody knew about. We will tell you if that is the case.

Design the Data Flow

We plan exactly how the data will move between systems, what happens when something goes wrong, and how errors will be handled. You approve the design before any code gets written.

Build and Document the Integration

We build the integration and document it so your internal team can understand what is happening and why. Integrations that nobody can maintain become tomorrow's problem.

Test With Real Data

We test with real data in a staging environment before the integration goes live. Edge cases that only exist in your actual data get caught early.

Deploy and Monitor

We deploy the integration into production and set up monitoring so problems get flagged before they cause real damage. We stay available for updates when one of the connected systems changes.

The Kinds of Integrations We Build

Integration work pays for itself quickly when a team is spending hours every week moving data by hand.

  • CRM and accounting integrations so sales data stops getting re-entered.
  • E-commerce and inventory syncs so stock levels stay accurate everywhere.
  • Support and project management integrations so tickets do not get lost between tools.
  • Marketing automation tied into sales and customer data.
  • Custom APIs for partners and customers who need access to your data.

We Have Built More Integrations
Than We Can Count

Every platform we own has to talk to something else. Billing systems, email providers, payment processors, support tools. We have built more integrations than we can count.

We Build Integrations That Do Not Break Silently

Monitoring and alerting come standard. You find out about problems before your customers do.

Documentation Your Team Can Actually Read

Every integration comes with clear documentation so the next developer to touch it does not have to guess.

Built for Real-World Failures

APIs go down. Rate limits get hit. Data comes in malformed. We build for the bad days, not just the good ones.

Honest Recommendations

If a no-code tool like Zapier can do the job for a fraction of the cost, we will tell you. We do not bill for custom work that does not need to be custom.

Questions We Hear a Lot

We build and scale custom software — SaaS platforms, internal operations tools, mobile apps, dashboards, and API/AI integrations. We also own and operate seven of our own SaaS products, so your build follows the same standards we hold ourselves to.

We partner with founders, established businesses, and enterprise teams across a range of industries — anywhere there’s a manual process worth automating with software that actually ships.

We start consultative: we learn what you’re trying to solve and recommend the right solution before any code is written. From there we scope, design, build, and support — with clean code and documentation your team can keep running after handoff.
