Works with QuickBooks Online · Memento Database · Cloud & Private Server

How it works

Up and running in minutes

Step 1

Connect

Link your Memento server (cloud or private) and authorize your QuickBooks company with a secure OAuth connection. Takes about two minutes.

Step 2

Map

Choose a sync map that defines which Memento libraries match which QuickBooks entities — customers, products, invoices. Use the built-in standard map or build your own on Pro.

Step 3

Sync

MQSync runs on a schedule — hourly, every 15 minutes, or on webhook trigger. Your data stays current in both systems without you lifting a finger.

Invoice flow

📱 Job created in Memento

📄 Invoice created in QuickBooks

✉️ Invoice emailed to customer

MQSync splits invoice creation and sending into separate scheduled tasks — so you can review drafts before they go out to customers.

Features

Built for the way you work

Not a generic integration tool. MQSync is purpose-built for Memento + QuickBooks with features no other connector offers.

Invoice PDF write-back

After QuickBooks generates an invoice PDF, MQSync automatically attaches it back to the original Memento job entry. Your field team always has the invoice on their phone.

True bidirectional sync

Customers and products sync in both directions. Add a customer in QuickBooks — they appear in Memento. Update a product in Memento — QuickBooks stays current.

Conflict resolution

When the same record changes on both sides simultaneously, MQSync flags it for your review instead of silently overwriting. You decide which version wins — QuickBooks or Memento.

Private server support

Connect to your own Memento Private Server for unlimited data volume, no API rate limits, and full data sovereignty. Available on Business and Pro plans.

Flexible scheduling

Run syncs manually, on an hourly schedule, every 15 minutes, or trigger instantly via webhook on Pro. Different tasks can run on different schedules — invoice creation hourly, sending daily at 10am.

Encrypted & secure

All API keys and OAuth tokens are encrypted at rest using Fernet symmetric encryption. QuickBooks authorization uses the official OAuth 2.0 flow — MQSync never sees your QB password.

Common questions

Memento Database is a flexible mobile database app for Android and iOS. It's widely used by field teams — repair technicians, sales reps, inspectors — to capture job information on their phone or tablet. MQSync bridges that field data into QuickBooks automatically.

Yes. MQSync connects to QuickBooks Online via the official Intuit API. You need an active QuickBooks Online subscription. QuickBooks Desktop is not supported.

Invoices always originate in Memento — this is by design. Pulling historical QuickBooks invoices into Memento would create noise for field teams who only care about active jobs. Customers, products, and accounts can be seeded from QuickBooks into Memento when you set up a project.

MQSync detects the conflict and flags it for review in your dashboard instead of silently overwriting one side. You see both versions and choose which to keep. No data is lost.

All API keys and OAuth tokens are encrypted at rest. QuickBooks is connected via the official Intuit OAuth 2.0 flow — MQSync never sees your QuickBooks password. Connections are over HTTPS and data is not stored beyond what's needed for sync operations.

Yes. No contracts, no lock-in. Cancel from your account settings and your subscription ends at the current billing period. Your data remains accessible until the period closes.

Memento offers a self-hosted server option in addition to their cloud service. The cloud API is rate-limited to 10 requests per minute. If you have large data volumes or need faster sync, a private server removes that limit entirely. It is optional — MQSync works with the standard Memento cloud on all plans.

Your jobs in Memento. Your books in QuickBooks. Always in sync.
