Which direction does payroll GL data flow between Visma and Paylocity?

GL data flows from Paylocity into Visma. Earnings, deductions, and pay summaries from Paylocity are mapped to Visma GL accounts and posted after each payroll run. Employee records flow the same direction so Visma headcount reflects Paylocity hires and terminations. Visma GL is read-only; ml-connector never writes back into Paylocity.

How does ml-connector handle the OAuth tokens and rate limits on both sides?

ml-connector obtains Bearer tokens from both systems and caches them until expiry. Visma requires a new token on every refresh; Paylocity tokens are valid for 3600 seconds. Both systems enforce rate limits; ml-connector backs off on 429 responses and retries with exponential jitter. Paylocity client secrets rotate annually, and ml-connector tracks rotation dates to request new credentials in time.

How are Paylocity earnings and deductions mapped to Visma GL accounts?

Each earning type and deduction code in Paylocity is mapped to a Visma GL account and cost center dimension in the integration configuration. Before posting, ml-connector validates that the account code and dimension values exist in Visma and match the company's chart of accounts. Invalid combinations are rejected with an audit entry rather than posted incorrectly.

Visma and Paylocity integration

Visma.net runs your Nordic ERP and general ledger. Paylocity runs US payroll and HR. Connecting the two keeps your GL accounts aligned with payroll costs and your employee roster in sync. Each pay cycle, payroll earnings and deductions from Paylocity post into Visma's general ledger mapped to the correct GL accounts and dimensions, and employee data flows from Paylocity back to Visma so your headcount stays current. ml-connector handles the OAuth flow on both sides, the GL mapping, rate-limit retries, and a full audit trail.

How Visma works

Visma.net is a cloud-based Nordic ERP and accounting platform that exposes suppliers, invoices, customers, general ledger accounts, cost centers (dimensions), employees, timecards, and expense claims through REST JSON APIs. Authentication uses OAuth 2.0 client credentials grant via Visma Connect, requiring client_id, client_secret, and tenant_id; all API calls must include the ipp-company-id header. Visma supports both webhooks (one-time delivery with no automatic retry) and delta polling via lastModifiedDateTime on list endpoints. Test clients are rate-limited to 500 calls per hour per company, and tenant approval is required before a service connector can access customer data.

How Paylocity works

Paylocity is a cloud-based HCM and payroll platform for US mid-market businesses, exposing employees, pay statements, earnings, deductions, punch data, companies, work locations, and positions through REST JSON APIs. Authentication uses OAuth 2.0 client credentials, obtaining a Bearer token valid for 3600 seconds from the Paylocity token endpoint. The API enforces TLS 1.2 minimum and requires annual client secret rotation. Paylocity supports webhooks for events including New Hire, Employee Change, Termination, and Payroll Processed, with automatic 30-minute retries up to 24 hours on failure, but webhook payloads carry only identifiers; full record data must be fetched separately via API calls.

What moves between them

Employee records and payroll GL data flow from Paylocity into Visma after each Paylocity pay cycle completes. ml-connector reads employees, earnings, deductions, and pay statements from Paylocity, maps the earnings and deductions to Visma GL accounts and cost center dimensions, and posts the payroll GL entries into Visma's general ledger. Employee changes (hires, terminations, profile updates) sync from Paylocity into Visma's employee master to keep headcount and organizational structure aligned. GL postings are permanent in Visma; ml-connector never writes back to Paylocity.

How ml-connector handles it

ml-connector obtains and caches OAuth tokens from both Visma and Paylocity, refreshing each before expiry (Visma requires a new token on every expiry; Paylocity tokens live 3600 seconds). It listens for Paylocity webhook events such as Payroll Processed and Employee Change; when events arrive, it fetches the full record payload from Paylocity's API (since webhook payloads carry identifiers only), maps the earnings and deductions to Visma GL accounts using the dimension hierarchy (cost center plus account code), and posts the GL transactions into Visma with optimistic locking via ETag. Visma dimensions and GL account codes are validated before posting to prevent invalid account combinations. Because Paylocity requires annual client secret rotation and both systems enforce rate limits, ml-connector tracks rotation dates and backs off on 429 responses, retrying with exponential jitter. Every record carries Visma's tenant_id and Paylocity employee_id for cross-reference, and the full posting is audited so any GL entry can be traced back to the original Paylocity pay statement.

A real-world example

A US manufacturing company operates a Nordic subsidiary with headquarters in Sweden. The subsidiary uses Visma.net for ERP and GL management in SEK, and the parent company uses Paylocity for all US payroll in USD. Before the integration, every payroll cycle the finance team exported pay register summaries from Paylocity, manually translated the earnings and deductions to GL account codes, converted USD to SEK at the day's rate, and posted the labor costs into Visma's general ledger by hand. Reconciliation between HR headcount in the subsidiary and the GL labor accounts consumed days of month-end close. With Paylocity and Visma connected, each Paylocity pay cycle automatically posts the labor GL entries into Visma's accounts, and employee changes sync without re-keying. The GL reconciliation step is eliminated, and the month-end close timeline shortens by two days.
