Bill Pay lets you:

  • Pay vendors and reimbursements from your ImpactGraph account

  • Collect vendor banking and tax information securely

  • Code expenses before approval so your fiscal sponsor has full context

This guide will walk you through the steps to initiate a bill pay to ensure timely and accurate processing.


Accessing Bill Pay

  1. Log in to ImpactGraph.

  2. In the left-hand navigation, click Bill Pay.

From here, you can:


Creating a new bill payment request

  1. On the Bill Pay page, click Add new bill in the top right corner.

  2. You’ll see a wizard-style flow (multi-step form) instead of the old side panel.

Step 1: Upload the invoice & choose a merchant

  1. Upload the invoice from your computer (drag and drop or file picker).

    • The invoice will display on the right-hand side for easy reference.

  2. Under Merchant:

    • Select an existing merchant, or

    • Click Create new merchant if this is a new vendor.

For a new merchant:

  • Enter the merchant name (e.g., Tech Nova Solutions).

  • Add a contact email (e.g., [email protected]).

  • If the bill is more than $600 for the fiscal year, toggle/request a W-9 so the vendor can submit tax information.

  • Click Create merchant.

When you create the merchant with an email, ImpactGraph can send them a link to complete their banking and profile information, so you don’t have to collect it manually.

Step 2: Enter bill details & upload supporting documents

Using the invoice preview on the right, enter:

  • Invoice number

  • Scheduled payment date (e.g., tomorrow)

  • Amount

You can also upload:

  • Additional documents related to the bill (supporting backup, contracts, packets, etc.).

  • You can upload each document separately

All uploaded documents are included in the approval packet your sponsor reviews.

Step 3: Code the invoice before approval

One of the biggest updates is that you can now fully code the bill before sending it for approval:

  • Choose a ledger account (e.g., Contractors).

  • Select a funding source (e.g., General Program Funds).

  • Add a memo describing what the expense is for (e.g., General security use).

  • If needed, click Add split to split the bill across multiple ledger accounts and/or funding sources.

This coding gives your fiscal sponsor full context during the approval process, reducing back-and-forth.

Step 4: Review & submit for approval

On the final step, you’ll see a summary of:

  • Merchant details

  • Invoice number, date, and amount

  • Scheduled payment date

  • Coding (ledger account, funding source, splits)

  • All uploaded documents and attachments

Here you can:

  • Save draft – if you’re not ready to submit yet.

  • Send for approval – to send the bill to your fiscal sponsor.

After you submit:

  • The bill moves into Waiting for approval.

  • Your fiscal sponsor receives an email letting them know it’s ready to review.

Once approved, the bill moves to:

  • Scheduled – payment has been approved and is queued.

  • Paid – once the payment has been successfully processed.

Your coding and documents stay attached throughout; you don’t have to redo that work after approval.


What the vendor sees

While a bill is waiting for approval, the vendor can complete their profile via the email link ImpactGraph sends (if you didn’t already have their info).

Make sure vendors know that incorrect or missing address/bank info can cause payments to fail or go to the wrong place.


Payment dependencies & notifications

A bill won’t pay out if:

  • The merchant is missing required banking info

  • Tax documents (like W-9) are required but not completed

  • Your fiscal sponsor has not approved the bill

ImpactGraph will:

  • Hold the payment until everything is complete.

  • Notify you when the merchant has finished entering required information, so you know the bill is ready to move forward.

Compliance and Documentation

Payments that you submit should be consistent with your financial policies and any specific agreements with your fiscal sponsor. Key compliance steps include:

  1. Record-Keeping: Maintain memos and receipts of all transactions and card usage for compliance and transparency purposes. All transactions are logged and can be reviewed in your transaction dashboard.

  2. Financial Controls: ImpactGraph monitors transactions for security and compliance. Bill Pay should only be used for approved project expenses that align with the goals and restrictions of the sponsored organization.​
