Two-Way Contact Sync Between CRM and Accounting Software
Your CRM says the customer is at 14 Oak Avenue. Your accounting system says 22 Elm Road. One of them is wrong, and the invoice you sent last week just bounced. Every company running separate sales and finance systems eventually hits the same wall: nobody knows which record is the truth.
We build the bidirectional sync that keeps both systems current, automatically.
Sound Familiar?
These are the exact issues businesses face when contact data lives in two separate systems:
- A customer updates their billing address in the CRM and nobody tells finance, so next month's invoice bounces
- New clients are entered in both systems by different people, creating duplicates with conflicting details
- Sales checks accounting for payment status; finance checks the CRM for contact details. Neither trusts the other's data
- Month-end reconciliation means manually comparing customer lists across two systems, record by record
- One in five invoices goes out with the wrong address, wrong VAT number, or outdated payment terms
B2B contact data decays at 2.1% per month. Without automated sync, roughly one in four of your customer records will be outdated within a year. That means invoices going to old addresses, statements reaching people who left the company months ago, and payment terms nobody agreed to.
Bidirectional Sync in Action
Change a contact in either system and the other updates automatically. No copying, no re-keying, no delays.
Contact Updated in CRM
Sales updates a customer's phone number or billing address after a call
Accounting Syncs Instantly
The matching customer record in accounting updates with the new details within minutes
Changes Flow Back Too
Finance updates payment terms or a VAT number in accounting, and the CRM updates to match
Single Source of Truth
Both systems always agree. Invoices go to the right address. Reports use the same data.
Everything You Need for Reliable Customer Data Sync
Bidirectional Contact Sync
Create or update a contact in either system and the change propagates automatically. Name, email, phone, billing address, VAT number, and payment terms stay identical everywhere.
Intelligent Duplicate Prevention
Before syncing, each record is matched against existing entries on email, company name, and registration number. New contacts are created only when no match exists.
Real-Time Field Mapping
CRM fields map to the correct accounting fields: billing addresses, tax codes, tracking categories, and currency preferences. No manual translation needed.
Conflict Resolution Rules
When the same field is changed in both systems simultaneously, configurable rules decide which update wins, so your team never has to arbitrate manually.
Change Audit Trail
Every sync event is logged with timestamp, direction, and the fields that changed. Your operations team can trace any record back to its source in seconds.
Error Alerts and Auto-Retry
If a sync fails (API timeout, validation error, rate limit), the system retries automatically and only alerts your team when human input is genuinely needed.

Frequently Asked Questions
How long does it take to set up two-way contact sync?
A standard bidirectional sync between one CRM and one accounting platform takes 2 to 4 weeks from scoping to go-live. Simple one-way syncs can be live within a week. More complex setups involving multiple subsidiaries or custom validation rules take closer to 6 weeks.
Which CRMs and accounting systems can you connect?
We have built two-way contact syncs between HubSpot, Pipedrive, Salesforce, Zoho CRM, Monday.com, and Freshsales on the CRM side, and Xero, QuickBooks, Sage (including Pastel), Zoho Books, NetSuite, and FreshBooks on the accounting side. If both systems have an API, we can connect them.
What happens when the same contact is updated in both systems at the same time?
Our sync includes configurable conflict resolution rules. You can set one system as the master for specific fields (for example, the CRM always wins on phone number, accounting always wins on billing address), or apply a "most recent change wins" policy. Every conflict is logged so your team can review edge cases.
Will this create duplicate records in our systems?
No. The integration includes intelligent matching on email address, company name, and registration or VAT number before creating any new record. Existing duplicates can also be identified and flagged during the initial setup.
What about data security and privacy?
All data is transmitted over encrypted connections (TLS 1.2+). We do not store your contact data on our servers. The sync runs directly between your two systems using secure API credentials that you control. We can also configure field-level exclusions if certain data should not be synced.
How much does a two-way contact sync cost?
Simple one-way contact syncs start from around R15,000. Bidirectional syncs with conflict resolution and custom field mapping typically range from R25,000 to R60,000. Most clients with 50 or more active customers see full ROI within 2 to 3 months through time savings and reduced errors alone.
Stop Maintaining Two Versions of the Truth
If your sales and finance teams are still re-keying customer details between systems, you are paying for a problem that two-way sync eliminates entirely.
