InvoiceQuickly + ADP: Streamline Contractor Invoice-to-Payment

For mid-size and enterprise businesses using ADP, contractor invoice management is often a manual pain point. InvoiceQuickly collects and validates contractor invoices, then pushes approved payments to ADP for processing β€” eliminating spreadsheets and manual payroll entry.

How It Works

1

Connect ADP

Link your ADP account to InvoiceQuickly via ADP Marketplace.

2

Map contractor profiles

Match InvoiceQuickly contractors to ADP contractor records for seamless data flow.

3

Invoice submission and approval

Contractors submit invoices. You approve in InvoiceQuickly with configurable approval workflows.

4

Push to ADP

Approved invoices sync to ADP for payment processing in the next pay cycle.

Key Benefits

  • Eliminate manual contractor payment data entry in ADP
  • Configurable approval workflows before payments reach ADP
  • Complete audit trail from invoice submission to ADP payment
  • Support for project codes, cost centers, and GL mapping
  • Works with ADP Workforce Now and ADP Run

Best For

  • Mid-size companies managing 50+ contractors through ADP
  • Professional services firms with project-based contractor billing
  • Organizations needing approval workflows before contractor payments

Setting it up

Setup takes 5-15 minutes depending on whether you have an existing ADP account. Prerequisites: active ADP account with admin access, your InvoiceQuickly workspace, and the relevant API permissions or OAuth authorization. From Settings β†’ Integrations β†’ ADP, follow the connection flow (OAuth for most, API key for some specialized tools). The integration syncs bidirectionally where supported β€” invoice creation in one system reflects in the other. Initial setup includes mapping data fields between systems (customers, products, payment methods, tax codes).

Best practices

Define one source of truth for customer data

When you connect ADP, decide which system owns customer records. Most teams keep their primary CRM/ERP as the source of truth and let invoices sync into it. This prevents duplicate customer creation and reconciliation issues.

Test with a small batch before production rollout

Before syncing all historical data or going live for daily operations, test with 5-10 invoices to verify field mapping, tax handling, and payment workflow. Adjust configuration based on test results.

Reconcile sync status weekly

Network failures, OAuth expirations, and edge cases occasionally cause sync gaps. A weekly reconciliation (compare invoice counts in both systems) catches issues early before they accumulate.

Document the integration scope for your team

Write a brief internal doc (one page) covering: which workflows use the ADP integration, who owns reconciliation, what to do when sync fails. Reduces support overhead as the team grows.

Common issues

Sync stops after working initially

Most common cause: OAuth token expired (typically 60-100 days depending on the ADP platform). Reconnect via Settings β†’ Integrations β†’ ADP. Set a reminder to refresh authorization every 60 days for critical integrations.

Field mapping creates duplicate or missing data

During initial setup, the field mapping between ADP and InvoiceQuickly may not catch every edge case. Adjust mapping in Settings β†’ Integrations β†’ ADP β†’ Field Mapping. Re-sync affected records after fixing.

Rate-limit errors during high-volume operations

ADP APIs typically allow 100-1000 calls per minute. Bulk operations (importing all customers, syncing 1000+ historical invoices) can hit rate limits. InvoiceQuickly handles backoff automatically; if you see persistent errors, retry during off-peak hours.
