Two-way integration and data sync between your CRM, ERP, accounting software, e-commerce store and Google Sheets. Custom integration development from $600 to $1,800 in 5 to 14 days.
The problem
A typical SME in Dubai or Bangalore runs Zoho or HubSpot for sales, Tally, QuickBooks or Zoho Books for accounts, Shopify or a custom store for orders and a dozen Google Sheets for everything else. None of them talk to each other, so staff re-enter the same customer, invoice and stock data three times, make mistakes, and the owner still cannot get a single view of the business.
What we build
We map the fields between your systems, then build a reliable sync service that moves records in both directions on a schedule or in real time via webhooks, with deduplication, conflict rules, retries and an error dashboard. Where n8n fits we use it; where it does not we write the connector in Node.js. Claude Code and Cursor generate the API clients and field-mapping code, DeepSeek handles the bulk test-data generation cheaply, and we verify every mapping with your team before switching it on. You receive the source code, the hosted sync and a fixed price that never exceeds $2,500.

FAQ
Third-Party Integration & Data Sync (CRM, ERP, Sheets): common questions
What does a CRM or ERP integration cost?
A one-directional sync between two tools starts at $600; two-way sync across three or more systems with conflict rules runs up to $1,800. The fixed quote never exceeds $2,500.
Our data is sensitive. Where does it flow?
Directly between your systems and a sync service hosted in your own cloud or n8n account. We do not store copies of your records, and API keys stay in your secret manager.
What happens when one of the tools changes its API?
The sync has version pinning and alerting, so you hear about a breaking change before data stops moving. We cover fixes during the warranty and offer a small monthly retainer after that.
