CRM Integration
Your productYour CRM

Both sides, in sync.

Bidirectional sync between Salesforce, HubSpot, or Pipedrive and your own stack — with conflict resolution, custom field mapping, event replay, and a health dashboard. So sales stops looking at yesterday and automations fire on the right contacts.

Each side owns some fields outright and shares the rest. The integration moves changes both ways — and the center seam is where ownership is decided, not where data goes to die.

Every field, mapped both ways.

Names rarely line up. The mapping — and the transformation — lives in one place you can read.

01The idea

Your CRM is the source of truth — until it isn't.

Every team agrees the CRM is canonical, right up to the moment the product knows something the CRM doesn't — a customer churned, upgraded, or changed their email an hour ago. Then sales is looking at yesterday, marketing fires a sequence at someone who already cancelled, and everyone quietly distrusts the data. A one-way sync only postpones the problem. We build the connection so changes flow both ways, conflicts are resolved by a rule you chose, and you can replay anything that went wrong — so the CRM stays the source of truth instead of just claiming to be.

02What you get
Bidirectional sync
01

Bidirectional sync

Changes flow both ways in near real time — not a nightly job, and not one direction with the other left to rot. Updates on either side reach the other in seconds.

Conflict resolution
02

Conflict resolution

When both sides edit the same field, an explicit policy decides the winner per field: source-of-truth, last-write-wins, or queue it for a human. No silent corruption.

Custom field mapping
03

Custom field mapping

Your thirty custom fields mapped both directions, including the transformations — picklists, enums, currencies, split names — in one place that's an edit, not an excavation.

Event replay
04

Event replay

Every change is recorded, so you can find a bad window, see exactly what each record looked like, and replay it through the corrected mapping without churning everything.

Health dashboard
05

Health dashboard

Lag, error rates, queue depth, and the status of each connection in one view — so you watch drift happen instead of hearing about it from an account manager.

Operator runbook
06

Operator runbook

A written handover for whoever's on call: what each alert means, how to re-authorise a revoked token, how to replay a batch, how to read the conflict queue.

When both sides change, who wins?

You choose the rule per field, before we build. It's explicit and visible — never buried in code.

01

Source-of-truth wins

The field has an obvious owner — billing status comes from your system, deal stage from the CRM. The owner's value always wins, full stop.

02

Last-write-wins

The field is genuinely either-side and low-stakes. Whichever edit is most recent, by timestamp, takes it — and the older value is logged in case.

03

Queue for a human

The field is too important to guess. Both versions are held side by side in a review queue until someone with context picks the right one.

No more “is this number right?”

The CRM and your product agree — and when they can't, you see it before a customer does.

03How we work
1

Map ownership

Per field: which system owns it, which can change it, and how the two names and shapes line up.

2

Decide conflicts

Pick the resolution rule for each shared field before a line is written.

3

Build the sync

Bidirectional flow with idempotency, retries, mapping, and the conflict policy in code.

4

Backfill & verify

Reconcile history both ways, prove the edges, and watch it under real load.

5

Hand over

Health dashboard, replay tooling, and the operator runbook so your team can run it.

Questions teams ask first.

Almost always it's a one-direction sync that's quietly fallen behind in one place. The CRM updates, but the change never makes it back to the product — or it does, but only on a nightly job, so reps spend the whole day looking at yesterday. We make the sync bidirectional and near-real-time on the fields that matter, and we add a health dashboard so you can see lag instead of finding out from an angry account manager.

Tired of stale CRM data?

Tell us which CRM you run and where the data drifts — the fields sales doesn't trust, the automations firing on the wrong people. We'll map ownership, agree the conflict rules, and build the two-way sync that keeps both sides honest.
