Build payment-ready vendor records

Vendor onboarding is how you collect, review, and organize all the information your business needs before setting up and paying a vendor or contractor that you work with. A completed form is just the start. The goal is to have a complete record that can support payments, accounting, and tax reporting at year-end with fewer compliance gaps.

Collect the right information

Gather business, contact, W-9, taxpayer, and payment details in one structured workflow.

Review the details

Check each vendor’s submission for gaps or errors before making the first payment. Use the TIN matching feature to verify vendor TINs and ensure accurate tax reporting.

Prepare the record for payment

Keep all collected details together so that the same vendor record can help you with ACH or check payments as well as future tax reporting requirements and audits.

How vendor onboarding works in 5 steps

Many businesses still rely on manual processes and disconnected tools to collect data, handle invoices, and make payments, creating unnecessary risk of errors and delays. A streamlined vendor onboarding workflow helps your team collect the right information, resolve gaps, and move completed vendor records into the payment workflow.

  1. Invite the vendor or contractorAdd the vendor and send a self-onboarding invitation to collect the necessary information, instead of chasing details across multiple email threads.
  2. Collect business, tax, and payment detailsVendors submit everything through that dedicated self-service portal (xForce) free of charge, including W-9 and bank details.
  3. Identify missing informationYour finance team reviews each submission and follows up with the vendor if any corrections/updates are required.
  4. Review tax informationUse TIN matching to verify that the taxpayer name and TIN matches with the IRS database.
  5. Move the vendor into the payment workflowOnce all required details are verified, you can initiate the payment against the vendors and sync the data with the accounting system. The eligible payments then get auto-populated for the year-end 1099 reporting.

Start your 1099 prep at onboarding

Collecting vendor tax information early reduces the need to reconstruct records when 1099 preparation begins. Zenwork Payments supports this with vendor files that are updated throughout the year and connected to payment workflows.

  • Collect W-9 information upfront

    Ask for the W-9 during onboarding, not after payments have gone out.

  • Validate taxpayer information

    Use TIN matching to catch mismatches between the vendor’s name and TIN.

  • Fix missing details

    Ask for corrections or missing information before the record moves on to payments and reporting workflows.

  • Keep tax data connected

    Store the W-9 and taxpayer details with the vendor profile so they’re ready for 1099 preparation during the tax season.
