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.

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
  1. Job created
    in Memento Database
  2. Invoice created
    in QuickBooks Online
  3. PDF attached
    to the Memento entry
  4. Invoice sent
    to the customer via email

MQSync splits invoice creation and sending into separate scheduled tasks — create or update invoices in QuickBooks from Memento, and control exactly when each one is delivered to your customer.

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 a record is edited in both Memento and QuickBooks between syncs, MQSync flags it for your review — no silent overwrites. You decide which version wins. On Pro custom maps, per-field direction rules define the authoritative source for each field, preventing conflicts automatically.

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 QuickBooks password.

Built to extend

Your Memento libraries, your workflow

MQSync syncs the fields it knows about — and leaves everything else to you. Add your own fields alongside the standard ones and build the workflows your team actually needs.

Memento is a flexible database — your libraries can contain far more than what MQSync maps to QuickBooks. Photos, checklists, driver notes, calculated fields, route links — anything your team needs lives right alongside the synced data, untouched by MQSync.

MQSync only reads and writes the fields it's configured to sync. Everything else is yours.

This separates MQSync from point-to-point automation tools like Zapier or Make, which treat your data as a pipeline and nothing more.

Real-world example

Travel cost on every job

A field-service client adds a custom travel line to each job entry in Memento. A single tap opens Google Maps with directions from the technician's current location to the customer's address. Travel duration and fare are entered on the spot, and the cost is calculated automatically inside Memento.

MQSync syncs the job to QuickBooks as an invoice — including the travel line. The routing logic stays exactly where the technician needs it: on their phone, in Memento, offline-capable.

FAQ

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.
No. MQSync is built for QuickBooks Online US only. Canadian, UK, Australian, and other regional editions are not supported. Regional versions of QuickBooks Online differ in their data models — tax fields, account structures, and localized entities — and supporting them properly would require a separate implementation. If your QuickBooks company is outside the US, MQSync will not work for you.
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.
Yes. Edit the job entry in Memento and trigger a sync action — MQSync will update the existing QuickBooks invoice in place using a sparse update (the QBO API's operation=update&sparse=true), so only the changed fields are written and QB-managed data is preserved. No duplicate invoice is created. The revised PDF is fetched from QuickBooks and written back to the Memento entry automatically, replacing the previous one. If the invoice was already sent to the customer, the updated invoice can be re-sent via the separate Invoice — Send task.
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. On Pro custom maps, you choose the sync direction per entity — one-way or bidirectional. For bidirectional entities, per-field direction rules define which system is authoritative for each field, preventing conflicts automatically without manual review.
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.
On the Pro plan, each sync task gets a unique webhook URL. You add a short script to any Memento script — an on-create or on-update trigger, or a manual action script a user runs. When the script executes, MQSync queues a sync run instantly instead of waiting for the next scheduled poll.

Because Memento needs a few seconds to push the saved entry to its cloud server, the script includes a configurable delay (default 5 seconds). The URL and a ready-to-paste script are generated automatically on the task detail page — no manual configuration needed.
We accept all major credit and debit cards (Visa, Mastercard, Amex) as well as PayPal. Payments are processed securely by Paddle — MQSync never sees or stores your card details.
The charge will show as PADDLE.COM* MQSYNC on your bank or card statement. Paddle acts as the merchant of record for all MQSync subscriptions.
Yes. Paddle automatically handles VAT and sales tax and issues compliant invoices for every payment. You can download invoices from your account's billing page at any time.
We offer a 30-day money-back guarantee on your first payment if MQSync doesn't work for your setup — just contact us within 30 days of your first charge. Subsequent billing periods are non-refundable. See our refund policy for full details.
