Why am I seeing old invoices?

Last updated: February 17, 2026

Summary

You may see older invoices in Tabs for one of two reasons:

  1. Tabs generated them from your contract terms (including past-dated invoices).

  2. They were synced into Tabs from your ERP integration as legacy invoices.

Both exist to ensure accurate revenue reporting and reconciliation.

Why Tabs Generates Historical Invoices

Tabs is designed to maintain complete financial continuity. Older invoices may appear because Tabs:

  • Generates invoices for the full duration of a contract, including periods before your go-live date

  • Syncs historical invoices from your ERP to preserve reporting consistency

These invoices support accurate revenue reporting, ARR calculations, reconciliation, and month-end close.

Historical Invoices Generated by Tabs

When a contract is processed, Tabs generates all invoices defined in that contract — even if some invoice dates are in the past.

This ensures:

  • Revenue reflects the full contract value

  • Historical billing aligns with contract terms

  • Reporting remains complete

What should I do with these?

If those invoices were already sent outside of Tabs, mark them as Sent Off Tabs.

Invoices marked Sent Off Tabs:

  • Continue to count toward revenue and reporting

  • Do not impact aging or DSO

  • Do not affect cash forecasting

  • Will not send reminders

  • Cannot be re-sent through Tabs

If you prefer not to generate invoices prior to a certain date, your implementation manager can set a Cutover Date to prevent historical invoice creation.

Legacy Invoices from Your ERP Integration

If you have an ERP integration enabled, Tabs may sync historical invoices that were originally created in your ERP system.

These invoices:

  • Reflect invoices previously issued outside of Tabs

  • Ensure reporting continuity across systems

  • Support reconciliation and accurate financial records

They may appear in Tabs even if they were created before you began using the platform.

Best Practice

Most merchants:

  • Allow historical invoices to ensure reporting accuracy

  • Mark previously sent invoices as Sent Off Tabs

  • Use Tabs for invoicing and collections going forward

This approach preserves complete revenue reporting while keeping aging, forecasting, and collections clean.
