What This Workflow Does

For freelancers, consultants, and small businesses, managing contacts across different platforms is a constant, time-consuming chore. You add a new client's details to Google Contacts after a meeting, but then you must manually re-enter that same information into Lexoffice to create an invoice. This duplication is not just tedious; it's error-prone. Misspelled names, wrong email addresses, or incorrect tax IDs can lead to payment delays and unprofessional communication.

This automation solves that problem by creating a seamless bridge between your contact management and accounting systems. It acts as a diligent assistant that works in the background. Once set up, it periodically checks your Google Contacts for new additions and automatically creates corresponding contact entries in your Lexoffice account. This ensures your financial records are always populated with the latest, most accurate client information, the moment you need to issue an invoice or record a transaction.

The workflow is designed to run on a schedule you control (daily at 8 AM by default), providing a reliable, hands-off solution. It transforms a fragmented, manual process into a streamlined, automated data flow, freeing you to focus on billable work instead of administrative data entry.

How It Works

The automation follows a logical, step-by-step process to ensure data is transferred accurately and efficiently.

Step 1: Scheduled Trigger

The workflow is initiated by a schedule module. By default, it's set to run once a day at 8:00 AM, checking for any new contacts added in the last 24 hours. You can easily adjust this frequency to hourly, weekly, or trigger it based on other events.

Step 2: Fetch New Contacts from Google

The automation connects to your Google Contacts via a secure OAuth connection. It searches for contacts created since the last successful run, filtering out any previously processed entries to avoid duplicates.

Step 3: Map and Format Contact Data

Each new contact's information—like name, email address, phone number, and company—is extracted. The workflow then maps these Google Contact fields to the correct corresponding fields in Lexoffice's contact structure, ensuring data lands in the right place.

Pro tip: You can customize this mapping to include custom fields from Google Contacts, such as "Job Title" or "Notes," and have them populate specific fields in Lexoffice for better client segmentation.

Step 4: Create Contact in Lexoffice

The formatted contact data is sent to Lexoffice via its API. The automation instructs Lexoffice to create a new contact record, populating it with all the provided details. A successful creation is logged, and the process moves to the next contact.

Step 5: Error Handling & Logging

If an error occurs (e.g., a required field is missing, or the API is unavailable), the workflow can be configured to send you a notification via email or Slack. This allows for manual intervention if needed, ensuring no contact slips through the cracks.

Who This Is For

This automation is a game-changer for any professional or business that uses Google for contact management and Lexoffice for accounting and invoicing.

Freelancers & Solo Consultants: Perfect for individuals who wear all the hats. It eliminates the need to switch between apps to copy-paste client info, saving precious time for client work.

Small Business Teams: Ideal for teams where sales or support staff add contacts to a shared Google directory, and the finance person needs them in Lexoffice. This automation ensures seamless inter-departmental data flow.

Agencies & Service Providers: Beneficial for businesses that onboard multiple new clients per week. Automating this step accelerates the invoicing cycle and improves data consistency across sales and finance.

What You'll Need

  1. A Make.com account (free tier available). This is the platform where the automation runs.
  2. A Google account with Contacts populated. You'll need to grant Make.com limited access to read your contacts.
  3. A Lexoffice account with an active subscription. You'll need API access credentials from your Lexoffice settings.
  4. Basic information about your contact fields (e.g., which fields are mandatory in Lexoffice for contact creation).

Quick Setup Guide

Getting this automation live takes about 10-15 minutes.

  1. Clone the Template: Click the "Get This Workflow" button to copy the template into your Make.com account.

  4. Test the Flow: Add a test contact to your Google Contacts. Run the scenario once manually to see it fetch the contact and create it in Lexoffice. Verify the data appears correctly.
  5. Activate the Schedule: Turn on the schedule module. You can keep the daily 8 AM run or adjust the timing to match your business hours.
  6. Go Live: Activate the entire scenario. It will now run automatically on its schedule, syncing new contacts without any further action from you.

Frequently Asked Questions

Common questions about contact and accounting automation

Automating contact sync eliminates manual data entry, saving 2-5 hours per week and preventing costly errors like duplicate entries or incorrect details in invoices. It ensures your accounting system always has the latest client information, leading to faster invoicing and better cash flow management.

Without automation, you risk creating invoices with outdated addresses or sending them to wrong emails, which delays payments and hurts client relationships. Automation turns a reactive, error-prone task into a reliable, background process.

The main benefits include a single source of truth for contact data, reduced administrative workload, improved data accuracy for financial documents, and faster client onboarding. This integration streamlines operations from lead capture to invoicing, enhancing overall business efficiency.

For example, a marketing agency can have new leads from a form automatically become billable clients in their accounting system, shaving days off their project kickoff timeline.

  • Eliminates double data entry
  • Speeds up time-to-invoice
  • Reduces manual errors by 99%

Automated syncing ensures that every new contact added to Google Contacts is immediately available in Lexoffice with consistent, accurate details. This prevents manual transcription errors, ensures tax IDs and addresses are correct on invoices, and maintains a clean, audit-ready contact database for financial reporting.

Manual entry often leads to variations (e.g., "Co." vs. "Company"). Automation uses the exact data from the source, creating uniformity that is critical for accurate bookkeeping, VAT reporting, and professional client communication.

Yes, advanced automations can map custom fields like client industry, project codes, or referral sources from Google Contacts to corresponding fields in Lexoffice. This allows for sophisticated segmentation, personalized communication, and more detailed financial tracking without manual intervention.

While the basic template focuses on core fields, a customized version can be built to transfer any data point. This enables you to use contact tags from Google to automatically assign tax rates or payment terms in Lexoffice.

A well-built automation includes a deduplication check before creating a new record. It can search for existing contacts by email or name and either skip the duplicate, update the existing record with new information, or flag it for manual review, preventing clutter and data conflicts.

This is crucial for maintaining data hygiene. For instance, if a client updates their phone number in Google Contacts, the automation can be set to find their existing Lexoffice record and update that field, keeping all systems synchronized.

Yes, when using a trusted platform like Make.com, data is transferred using secure OAuth connections and encrypted in transit. You control the access permissions, and no sensitive data is stored permanently on the automation platform, maintaining compliance with data protection standards.

The connections are read-only or have specific scopes (like only creating contacts). Your login credentials are never exposed; instead, secure tokens are used, making it a safe and compliant way to integrate your business tools.
