Build custom REST APIs in Busy Accounting Software
Budget: ₹12,500 – ₹37,500 INR
I need Busy Accounting to talk fluently with my CRM. At the moment the two systems live in separate silos; my goal is to build reliable APIs inside Busy so customer, invoice and payment data can move automatically back and forth.
Scope
• Analyse Busy’s database structure and existing SDK (if any)
• Design REST-style endpoints that cover customer master, sales, receipts, outstanding balances and any related lookup tables
• Build and test those endpoints, ensuring secure authentication and clear error handling
• Map each field to the corresponding objects in the CRM so data stays consistent on both sides
• Package the solution with concise technical documentation and a quick-start guide for my in-house team
Acceptance criteria
1. All specified entities sync in both directions without manual intervention.
2. API responses meet agreed JSON schema and include status codes.
3. Stress test passes 500 sequential transactions with no data loss.
4. Implementation and setup can be replicated in a staging environment using only the supplied documentation.
Experience with Busy’s internal architecture, .NET or similar frameworks, and previous CRM integrations will help you hit the ground running. Let me know which CRM stacks you’ve connected before and your estimated timeline for each milestone.
