We Rebuilt Our CRM In 14 Days. Here's What We'd Do Differently.
We rebuilt our internal CRM in two weeks flat. Here's what we'd keep, and what we'd change next time.
Our old internal CRM had become the kind of system everyone routes around instead of fixing — five years of patched-on fields, a lead scoring model nobody trusted, and a UI slow enough that account managers kept their own spreadsheets on the side. We gave ourselves fourteen days to replace it. Here's what actually happened.
Why fourteen days, and why that was almost a mistake
The deadline was self-imposed, tied to the start of a new quarter so the sales team wouldn't have to migrate mid-cycle. It forced good discipline early — we cut scope aggressively and shipped a lean core instead of trying to replicate every feature of the old system on day one. It also nearly caused us to ship a broken lead-scoring model, because we didn't leave enough buffer to validate it against real historical data before go-live.
What we'd keep doing
- Building the lead pipeline and scoring logic first, everything else second — it's the part sales actually lives in daily
- Migrating a small live slice of real data early, instead of testing against seed data the whole build
- Giving account managers write access to a staging version by day 5, not waiting for a finished build to get feedback
What we'd change next time
We under-invested in UTM and source tracking in the rebuild, assuming we'd bolt it on after launch. That meant two weeks of leads with incomplete attribution data before we circled back to fix it — a gap that's still visible in our quarterly reporting. Attribution should have been in the core schema from day one, not a follow-up task.
We also skipped writing a rollback plan, betting the fourteen-day timeline left no room for one anyway. It worked out, but it was a bad bet — a two-hour rollback plan would have cost almost nothing and removed a real risk if the migration had gone wrong.
The actual result
Lead follow-up time dropped noticeably in the first month simply because the new system was fast enough that account managers stopped avoiding it. The bigger win wasn't a feature — it was adoption. A CRM the team actually opens voluntarily beats a more sophisticated one they route around every time.
