Visma integration is a seamless connection between your business systems and Visma’s API offerings, enabling automation of critical finance workflows such as invoicing, bookkeeping, payments, and reporting. By embedding Visma services directly into your application, you eliminate manual processes and reduce human error. This integration supports real-time data, customizable invoice templates, and a unified overview of all financial transactions. With our implementation, you gain a single dashboard that displays live status updates, giving you peace of mind and operational efficiency.

Our solution covers the full Visma API portfolio, including Visma eEkonomi for small businesses, Visma.net ERP for mid-sized companies, Visma Payroll for payroll management, and Invoicing & Approval services. We also support project accounting, time tracking, and cash flow forecasting. Each service can be turned on or off according to your needs, giving you flexibility to tailor functionality by company or department. The result is that you can offer your users accurate figures and streamlined processes in real time.

Our typical Visma integration projects run 4–6 weeks, but the exact timeline depends on the scope and complexity of your requirements. We begin with a discovery phase to analyze your existing workflows and define the API endpoints you need. Next, we design and build the integration layers, including authentication, data transfer, and error handling. After rigorous QA and user testing, we deploy first to staging and then to production, while providing training and support throughout. This phased approach ensures your integration is robust, secure, and thoroughly tested before going live.

To kick off a Visma integration, you need a Visma developer account and corresponding API credentials (client ID, secret, and any certificates). You’ll also need to provide details about your business processes — such as invoice templates, chart of accounts, VAT rates, and project data. If you plan to automate payroll, we’ll need your employee records and tax reporting parameters. Finally, share any branding requirements for email notifications or report formats so we can configure them during development. Once we have this information, we can set up sandbox access and begin testing immediately.

The Invoice Creation API lets you submit complete invoice data — customer details, line items, prices, tax rates, and payment terms — in a single POST request. Upon successful validation, Visma returns a JSON payload containing the invoice number, accounting entry reference, and a PDF URL for the invoice. You can specify output as PDF or e-invoice XML and include custom messages or references. After creation, you can immediately forward invoice data to your BI system or finance team, streamlining your handling process.

The Reporting API offers several endpoints for comprehensive financial visibility: `GetGeneralLedger` retrieves GL transactions, `GetTrialBalance` delivers trial balance summaries, `GetProfitAndLoss` returns income statements, and `GetVatReport` generates VAT reports. There’s also `GetProjectTransactions` for project accounting. Each response includes timestamps, account numbers, and amounts, enabling you to build live dashboards, automate report generation, or integrate with your BI tools.

Yes — with the Visma Invoice API, you can programmatically create and dispatch invoices directly from your system. Simply include the invoice data in your API call, and Visma returns the invoice as a PDF link or XML file for e-invoicing. You can then send it via email to the customer or route it to a print queue. Our integration also supports invoice template customization, allowing you to add logos, adjust layouts, or include specific terms before sending.

The Visma Payment API enables you to initiate and manage supplier payments via direct bank connections. You can send payment requests, retrieve status updates, and automatically post approved payments. The response includes a breakdown of amounts, exchange rates, and fees, offering transparency in the payout process. You can also schedule recurring payments and handle batch disbursements for optimized cash flow.

The Payroll API endpoint lets you schedule payroll runs and submit payroll data for selected employees. You send the pay period, wage types, tax withholdings, and bank account details in an API request, and Visma returns the payroll file as XML or CSV. You can then query payroll status or generate payslips. Automating payroll ensures timely, accurate payments and reduces manual administration.

Visma Cloud APIs support OAuth2 token-based authentication for all modern endpoints. For certain legacy SOAP services, you may need API keys or certificate-based authentication. We assist with setting up secure token refresh processes and managing credential storage according to best practices.

Yes — Visma provides separate sandbox and production endpoints so you can test your integration without affecting live data. In sandbox mode, you can simulate invoice creation, payment initiation, and report retrieval without real accounting entries. Once all workflows are validated, you simply switch base URLs and credentials to production. We help configure permissions and environments to ensure a smooth transition.

Visma’s Webhook service lets you receive automatic POST callbacks when events occur, such as `InvoicePaid`, `PaymentFailed`, or `PayrollPosted`. You register your callback URL and select which event types to subscribe to. Each notification includes a secure signature header you verify against your secret. This event-driven architecture allows you to update internal systems, trigger notifications, or drive workflows in real time with minimal polling.

Visma’s REST APIs accept and return JSON payloads, making integration straightforward in any language or framework. You specify the content type in request headers, and the API automatically validates JSON data. For legacy SOAP services or specialized endpoints, XML is also supported. Our integration layer abstracts these differences so you always interact with a unified JSON interface.
