Automate your application
API Development and Integration
Connect your software, automate your operations
Still spending hours on data entry? Struggling to keep your books up to date? Unsure if your numbers are telling the full story? We take your finances off your plate — so you can focus on what matters.
What do you need help with?
- Common use-case
A new contract is signed in your CRM
What it automates:
01
A folder structure is created in Google Drive
02
The client is created in QuickBooks with their billing information
03
The client is added to your monday.com database
04
All these elements stay linked for future operations
- Connecting existing apps
Integrating Existing Software
Connect what you already have
Most modern platforms (monday.com, QuickBooks, Dext, Plooto, Shopify, HubSpot, etc.) offer public APIs that let them communicate with each other. Our job: configure these connections to build a complete, automated ecosystem.
Result: zero manual data entry, zero forgotten steps, and your teams can find the contract info in any of these tools
What we typically integrate
- CRM
- Accounting
- Document Management
- Projects
- Invoicing
- Payments
And dozens of other combinations
- Building my own API
Custom API development
When public APIs aren’t enough, or when your system doesn’t have one at all, we build custom solutions. Two main scenarios
- Service #1
- Create
API design to extend your software
Your software doesn’t have a public API, and you want to build one — either for your own internal needs or to offer integrations to your clients or partners?
- Define the optimal architecture of your endpoints
- Built-in compatibility with future automation platforms like Zapier
- Maintainable setup your team can extend over time
Use-case
Your company develops an industry-specific software used by 50 clients. These clients want to connect your software to their own ecosystem (CRM, accounting, etc.). We help your team design the API that lets your clients automate their workflows with your data — a powerful sales argument and a strong retention driver.
- Service #2
- Connexion
We connect your existing API to Zapier as a Private App.
Your software already has an API, but it’s not available in Zapier. We build a Zapier Private App that turns your endpoints into reusable actions and triggers — so your team can drag and drop them into any zap, just like they would with Gmail, Slack, or Google Sheets.
- Custom Zapier App built around your existing API
- Your endpoints turned into reusable actions and triggers
- Maintainable setup your team can extend over time
Use-case
Your business runs on an in-house ERP, a niche industry platform, or a proprietary system with a working API but no presence on Zapier. We build a Private App that exposes its actions inside Zapier — letting your team automate workflows across all your tools as if a native integration had always existed.
