Keep QuickBooks and AWS S3 Data Connected and Synced in Salesforce
cmSync connects Salesforce with QuickBooks Online for two-way financial data sync and with Amazon S3 for secure, scalable file storage. Teams eliminate manual reconciliation, reduce data entry errors, and keep large files accessible from Salesforce records without hitting storage limits.




How cmSync Improves Data Accuracy, Storage Efficiency, and Compliance
Unified Financial and Document Data
Syncing CRM and accounting ensures every department works with accurate, up-to-date records; no duplicates, no mismatches, no confusion. Teams can sync customers, invoices, payments, and related financial records between Salesforce and connected systems while reducing manual reconciliation steps and duplicate data entry across departments.
Scalable, Cost-Efficient Storage and Backup
With AWS S3 sync, file storage scales as you grow; large archives don’t slow Salesforce down and you pay only for what you use. Securely archive contracts, invoices, borrower files, and historical documents in scalable cloud storage while reducing Salesforce storage usage and maintaining direct access from Salesforce.
Reliable Continuity and Compliance Readiness
Cloud-backed storage adds durability, security, and audit-friendly backup, protecting sensitive data and ensuring compliance even as volume and complexity increase. AWS S3-backed storage supports encrypted retention, disaster recovery readiness, and compliance initiatives aligned with HIPAA, SOC 2, GDPR, PCI, and internal data governance policies.
The Two Apps That Power cmSync
Sync customers, invoices, and payments in real time with two-way QuickBooks. Automatically keep financial and CRM records aligned between Salesforce and QuickBooks Online without relying on spreadsheets or manual updates.
Securely sync files and data between Salesforce and AWS in real time. Offload large documents, historical records, and attachments to AWS S3 storage without slowing down Salesforce performance or increasing storage costs.
Why Finance and IT Teams Choose cmSync for Data Sync
Uncluttered Salesforce That Stay Fast Over Time
By shifting large documents to S3 automatically, Salesforce stays lean, responsive, and easier to maintain even as teams grow and file volume explodes. IT teams can better manage Salesforce storage quotas and reduce performance issues caused by years of accumulated attachments and archived files.
Real-Time Visibility
Teams always see the latest financial data and file updates without checking multiple systems or waiting on sync. Finance teams can review invoice payments, customer balances, and reconciliation updates in real time, while IT teams maintain visibility into synced files and storage activity across connected systems.
Financial Accuracy That Protects Downstream Decisions
Clean, current QuickBooks sync means forecasts, approvals, and customer decisions rely on real numbers, not stale exports or reconciliations done days later. Finance teams can streamline month-end close processes, reduce accounting discrepancies, and improve confidence in operational reporting.
Cloud Durability Without Changing User Habits
AWS S3 handles long-term storage, backup, and retention behind the scenes, while users continue working inside Salesforce exactly as they do today. Teams gain enterprise-grade storage scalability and disaster recovery support without changing existing workflows or requiring additional user training.
Seamless Governance Across Systems
Audit trails, file visibility, and financial updates stay connected across Salesforce, QuickBooks, and AWS, making compliance easier and reducing the risk of data oversight. Compliance and IT teams can simplify audit preparation, retention tracking, and document traceability across financial and operational systems.
Resilience Built Into Daily Operations
Even as volume scales, file movement and data syncing continue uninterrupted, giving you confidence that essential processes won’t break during peak cycles. Whether during month-end processing, seasonal spikes, or high-volume document uploads, teams can maintain stable and reliable system performance.

Frequently Asked Questions
How does Salesforce–QuickBooks integration help with invoicing and payments?
Connecting Salesforce with QuickBooks lets teams create invoices directly from CRM records and track payments without switching tools. As soon as a customer pays, the status updates automatically in Salesforce, so sales and finance always see the same numbers.
Can I use Salesforce as an online invoice generator for QuickBooks?
Yes, many businesses do this every day. With the right integration, Salesforce can generate QuickBooks Online invoices using real customer, product, and pricing data already in the CRM. You get:
- Invoices created instantly
- Fewer manual entry mistakes
- Faster turnaround from quote to cash
Does QuickBooks Payments sync back to Salesforce automatically?
Absolutely. When a customer pays using credit card, ACH, or any QuickBooks Payments method, the update flows into Salesforce right away. That means:
- No waiting on finance for payment status
- No spreadsheets
- No manual reconciliation
Everyone sees the real paid/unpaid status while looking at the customer record.
What is the benefit of a true two-way QuickBooks–Salesforce integration?
A genuine two-way sync keeps customers, invoices, transactions, and product data aligned across both systems. Instead of fixing mismatches later, data stays consistent from the moment it is created.
It removes duplicate entry, prevents errors, and gives finance and sales a shared source of truth.
How does QuickBooks Online invoicing improve when connected to Salesforce?
When the two platforms work together, invoicing becomes much smoother. Here’s why:
- Sales creates invoices instantly using CRM data
- Finance sees real-time updates from payments
- Reminders and follow-ups can run automatically
It shortens the billing cycle and gives teams faster visibility into cash flow without changing how they already work.

I have been working with Cloud Maven and Team since 2018, we implemented their credit applications as well as used their onshore and offshore resources to complement our internal teams. We are very satisfied with the outcome of the projects that we did with them. The credit checker application saved us hundreds of hours of custom code to integrate credit bureaus into Salesforce.

We’ve recently been able to implement the Credit Checker and this is a great feature. It has cut our credit processing time down by probably 75 percent. Cloud Maven has been extremely professional to work with. They’re quick on their responses, very insightful and have walked us through the process. I highly recommend using them.
Our biggest challenge prior to getting credit checker was that we simply didn’t have a program in place to be able to run credit, which is a huge decision factor in our industry. With the credit checker, we were able to put a lot of customizations in place so that we can automatically run credit when certain information is in our system. This takes away a lot of manual labor from our processing team and we’re able to work more efficiently.

Just knowing that everything is securely and safely being sent as a healthcare organization gives us all a peace of mind.

Prior to lending manager, our challenge was to improve productivity with our submissions and sales team. This product makes the process and submitting applications more streamlined. Our sales productivity has increased and the time it takes to submit has been a lot quicker. Our overall satisfaction with Cloud Maven is a 5/5 especially with the quick response time during implementation from their team.
