Custom Moneybird integration development
Appfront builds custom Moneybird integrations that connect your administration with webshops, CRM systems, time tracking, subscription tools and your own applications. Through the official Moneybird REST API, we synchronise sales invoices, purchase invoices, contacts, products and hours, without duplicate entry and without error-prone manual work.
What is a Moneybird integration?
Moneybird is the online accounting package used by more than 400,000 Dutch entrepreneurs — mainly freelancers, self-employed professionals and SMEs. The package combines invoicing, quotes, purchase administration, VAT returns, time and project tracking and bank integrations in a single environment, with an open REST API for external integrations.
A Moneybird integration links that accounting to the other systems your business runs on: your webshop, CRM, subscription tool, time tracking or an in-house application. New customers land automatically as contacts in Moneybird, webshop orders become sales invoices, tracked hours become expense claims, and incoming payments are immediately reconciled against the right invoice.
Appfront builds these integrations to measure using the official Moneybird API. We tailor the scope, frequency and error handling to your actual business process, rather than a one-size-fits-all connector that only solves part of the problem.
Invoices without manual work
Sales invoices in Moneybird are created automatically from orders, contracts or subscriptions. PDF sending, payment reminders and direct debits are also handled through the API.
Contacts in sync
Customer and supplier details stay consistent between Moneybird and your CRM or webshop. New contacts are added automatically, and changes flow both ways.
Via the official REST API
Implementation through the documented Moneybird API using OAuth 2.0. We respect rate limits, provide clear error handling and use webhooks for real-time updates, with no scraping or reverse engineering.
Our development process for Moneybird integrations
We work to a methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your administration through to go-live and ongoing maintenance, every step is aimed at an integration that your accountant and team can rely on.
We map out which Moneybird entities are involved (invoices, contacts, products, hours), which direction the data should flow and which administration settings apply.
We design the integration, set up OAuth authentication with the correct scopes and define a strategy for retries, reconciliation and error handling.
Implementation with automated tests against a sandbox administration, structured logging and monitoring. You see working builds along the way.
A controlled go-live with data validation on your production administration, followed by ongoing management, monitoring and further development.
What a Moneybird integration delivers in practice
Every integration is built specifically for your business processes. Below are the features we most often deliver for organisations that want to connect Moneybird with the rest of their software landscape.
Webshop → invoices
Orders from Shopify, WooCommerce, Magento or Lightspeed automatically become sales invoices in Moneybird. Customer details, VAT rules by country and products are posted to the correct ledger account.
CRM ↔ contacts
Contacts stay in sync between Moneybird and your CRM, whether HubSpot, Pipedrive, Salesforce or a custom system. Sales can see outstanding invoices, while administration works with consistent customer data.
Hours → expense claims
Logged hours from tools such as Simplicate, TimeChimp or an in-house planning tool are converted into sales invoices in Moneybird, including project grouping and specific rate agreements.
Subscriptions & SaaS
For SaaS founders with recurring billing: integrations with Stripe, Chargebee or your own billing logic. Periodic invoices are created, sent and matched automatically against incoming payments.
Bank matching & transactions
Link bank transactions from additional sources to Moneybird and have them automatically reconciled against outstanding invoices. Useful when your bank integration via Ponto or a niche bank requires extra logic.
Reporting & dashboards
Financial data from Moneybird is combined with operational data in dashboards or tools such as Power BI, Looker Studio or Tableau. Get live insight into revenue, margins and outstanding invoices without Excel bridges.
Typical use cases in practice
Depending on your type of organisation, a Moneybird integration can look very different. We come across a number of patterns regularly, and for each of them we have a proven model.
Webshops & e-commerce
Webshops processing dozens to hundreds of orders a day cannot run on manual bookings. We connect the shop to Moneybird so that orders become invoices automatically, including VAT logic per country, discount rules and deviating product groups. See also our e-commerce development.
SaaS & subscription businesses
SaaS entrepreneurs invoice monthly or annually. An integration between their billing system (Stripe, Chargebee or custom) and Moneybird ensures that subscriptions, upgrades, prorated invoices and credit notes are booked automatically and without errors.
Business service providers
Consultancies, IT suppliers, design agencies and legal service providers bill based on hours or project phases. An integration with time tracking pulls hours and project costs automatically and converts them into sales invoices in Moneybird.
Franchise & multi-administration
Organisations with multiple entities, franchise branches or holding structures often manage dozens of Moneybird administrations. We build integrations that read and write data correctly per administration, including central reporting across entities.
Technology we use
We build Moneybird integrations with modern, well-maintained stacks. The choice depends on your other systems and preferences, so that your team or a future supplier can manage the integration without vendor lock-in.
If you record hours in TimeChimp alongside your own system, see our TimeChimp integration.
If you use Gekko alongside your own planning tool or app, see our page on a Gekko integration.
If your clients use MoneyMonk instead of Moneybird, see our page on a MoneyMonk integration.
If you use Silvasoft instead of Moneybird, see our page on Silvasoft integrations.
Why choose Appfront for your Moneybird integration?
Appfront has extensive experience with accounting and financial integrations for Dutch businesses. We always start with a thorough analysis of your administration setup and working processes. An integration must not only work technically, but also add practical value to the daily work of your bookkeeper and team.
For every integration, we write clear documentation and make sure your team, or any future supplier, can understand and manage the integration. No black box, but transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical side (APIs, webhooks, data model) and the functional side (chart of accounts, VAT rules, invoicing logic). This keeps communication short and speeds up decisions during the build.
See also our wider services around API integrations, middleware, custom software development and web app development.

Security and privacy in Moneybird integrations
Accounting data contains financial information, customer details and commercially sensitive figures. Part of it falls under the GDPR. Appfront approaches every Moneybird integration with that in mind: we do not store unnecessary data, we encrypt sensitive information in transit and at rest, and we document data flows for your record of processing activities.
Authentication runs via OAuth 2.0 with minimal scopes, meaning only the permissions the integration actually needs. Refresh tokens are stored securely in a secrets manager, and all API requests are logged for audit purposes.
More about our approach: information security policy and vulnerability disclosure policy.
- OAuth 2.0 with least-privilege scopes
- GDPR-compliant data processing and data minimisation
- Encryption in transit (TLS 1.2+) and at rest

Frequently asked questions about Moneybird integrations
Answers to the questions we are asked most often about custom Moneybird integrations.
A Moneybird integration is a technical link that allows the online accounting package Moneybird to exchange data with another system. This happens via Moneybird's REST API using OAuth 2.0 authentication. Common entities include contacts (customers and suppliers), sales invoices, purchase invoices, quotes, products and time tracking.
Moneybird has an App Store with ready-made integrations for popular combinations. Custom development makes sense when your combination isn't listed, when you need specific business logic (for example complex invoice lines, subscriptions or multiple administrations), or when an existing connector only covers part of the scope you need.
A simple one-way integration, such as pushing sales invoices from your own system, is typically production-ready within a few weeks. Bidirectional synchronisation of contacts, invoices and products between multiple systems takes more time, typically several months including testing and a controlled go-live.
We connect to the Moneybird REST API using OAuth 2.0. We build the integration layer in modern back-end stacks such as Node.js, Python, Laravel or .NET. For reliability, we set up webhooks, job queues and monitoring, so error situations (rate limits, network glitches) are handled automatically.
The investment depends on the number of systems to connect, the complexity of the data flows (one-way versus bidirectional), the number of entities (invoices, contacts, products, hours), the desired synchronisation frequency and the amount of custom development. We always provide a clear quote after a no-obligation analysis.
Yes. Integrations are built according to security best practices and Dutch privacy legislation. Authentication runs via OAuth 2.0 with limited scopes, data is encrypted in transit and at rest, and we minimise the scope of the data exchanged. All data flows are documented for your record of processing activities.
Yes. The Moneybird API works per administration ID. For organisations managing multiple administrations, such as accountancy firms or holding companies with several entities, we build integrations that correctly read and write the right invoices, contacts and ledger accounts for each administration.
Moneybird is widely used by freelancers and SMEs. An integration is especially valuable for businesses that use a webshop, subscription tool, time or project administration, CRM or their own application alongside Moneybird, and want to avoid maintaining data manually in multiple places.
