What is a historical backfill?


Historical backfill is the process by which Anrok gets your historical transactions to calculate your global tax obligation accurately. This process can be completed automatically (most efficient) or manually:

  • Automatic Backfill — This billing systems link is possible if you use billing systems like Stripe, Salesforce, Chargebee, (and more). Anrok can automatically fetch past transactions and populate them in Anrok for comprehensive and accurate nexus monitoring. You can decide later whether you would like to calculate tax on past transactions, pay the tax out of pocket, and include these in the first return.
  • Manual Backfill — If you do not have a compatible billing system, you can upload your company's historical transactions via CSV. Use the attached template to structure your transaction data before uploading to Anrok.

If you want to complete a manual backfill, you will first need to complete the Anrok backfill template. Filling out this template accurately will ensure the information is organized and structured correctly before adding it to your transaction history. Once the Anrok backfill template is complete, you can then manually backfill your historical transactions into Anrok. See Manually backfill your historical transactions.
