Plugsync vs custom development
Hand-building a HubSpot integration looks cheap on a slide. In practice it's €20-80k upfront, 3-6 months of engineering time, and ongoing tech debt your team owns forever. Plugsync ships the same capability in days, with monitoring and identity mapping included.
Cost comparison
| Item | Custom development | Plugsync |
|---|---|---|
| Initial build | €20-80k (3-6 months) | Hours to days |
| Yearly run cost | €10-30k maintenance + ops | $6-12k subscription |
| Time to first sync | 3-6 months | Under 10 minutes |
| Monitoring + alerts | Build it yourself | Built in |
| Identity resolution | Build it yourself | Built in |
| Conflict resolution | Build it yourself | Built in (source-wins / target-wins / most-recent) |
| Schema migrations + retries | Build it yourself | Built in |
| HubSpot API rate-limit handling | Build it yourself | Built in |
When custom development is the right call
Your integration logic is so domain-specific and high-leverage that it's a competitive moat, you have a dedicated integration team, and you need direct control over every byte of the wire format. In that case build it — and consider Plugsync as the backbone you build on top of (Enterprise plugin layer).
When Plugsync is the right call
You want a working integration this quarter, not next year. You don't want to staff an integration team to chase HubSpot API changes. You want monitoring, identity mapping, and an AI agent that configures the boring stuff for free.
