How Do I Keep Track of the Bills My Business Owes?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

Accounts payable is every bill the business owes but hasn’t paid yet. Enter each bill in your books when it arrives, with its due date, check it against what you actually ordered, and pay on a set schedule. A current bills list keeps you from paying late, paying twice, or paying a bill that isn’t real.

What this means

When a vendor sends a bill and you haven’t paid it, that amount sits in accounts payable, often shortened to A/P. It’s a liability on your balance sheet. Bills can come from suppliers, subcontractors, landlords, software companies, utilities, lenders, and tax agencies.

The Small Business Administration (SBA) lists accounts payable among the things someone in the business should be responsible for.

Made-up example: Maple Street Bakery used to pay bills whenever someone remembered. Now every bill is entered in the bookkeeping software the day it arrives. On Tuesdays, the owner reviews what’s due in the next two weeks, checks each one against the delivery slip, and approves payment. Recurring bills like the website host and phone service are on a list with renewal dates, so nothing lapses.

Why it matters

Late fees and interest add up.
Vendors may stop supplying you or ask for cash up front.
Duplicate bills get paid twice when there’s no central list.
Fake invoices get paid when nobody checks them against real orders (see 11.9.5 Payment Fraud).
Critical services lapse. A missed renewal can turn off your domain, website, or phone (see 13.1.3 Domain Renewal).

Who this applies to

Every business that receives bills. Even if you pay most things by card, track the card bill itself and any vendor that invoices you.

How to do it

Send all bills to one place, like a shared billing email address (see 12.1.2 Email Accounts and Shared Inboxes).
Enter each bill in your books when it arrives, with the vendor, amount, bill date, and due date.
Match the bill to what you ordered and received. Check the price, quantity, and delivery.
Approve before paying. Use your spending limits (see 10.6.1 Spending and Refund Authority).
Only pay approved vendors at bank details you’ve verified (see 10.6.3 Vendor Approval and Bank-Change Verification).
Pay on a set schedule, such as once a week, and pay by the due date.
Mark each bill paid with the date and method, and attach proof.
Keep a list of recurring bills with renewal dates, especially domain, hosting, phone, insurance, and licenses (see 10.9.1 Financial Calendar).
Run the unpaid bills report weekly to see what’s coming due.

Common mistakes

Bills scattered across personal email and paper piles.
Paying from the vendor’s email alone without checking the order.
No list of auto-renewals, so a card expires and a service shuts off.
Paying the same bill twice because it came by mail and email.
Ignoring tax bills and notices because they don’t look like vendor bills.

When to get help from a pro

A bookkeeper can enter bills and prepare a weekly payment list for you to approve. Questions to ask:

What’s the simplest approval process for a business my size?
How do I set up recurring bills so nothing lapses?
Which bills should I pay early to keep good vendor terms?

Bill’s note

[Bill: add a short note. For example, a client whose website or Google Business Profile phone number went dark because a hosting or phone bill went unpaid, and how you set up SiteSmarty’s renewal list.]

Questions people ask

What counts as accounts payable? Any bill the business owes and hasn’t paid yet, from suppliers, software, rent, utilities, lenders, or tax agencies.

How do I avoid missing a due date? Enter every bill when it arrives, run the unpaid bills report weekly, and keep a list of recurring renewals.

How do I avoid paying twice? Send all bills to one place and mark each one paid with the date and method.

Should I pay early or on the due date? Pay by the due date. Paying earlier only makes sense if the vendor offers a discount and your cash allows it.

Audit check

Question: Is every bill entered with a due date, matched to an order, approved before payment, and paid on time, with recurring renewals tracked?
Pass looks like: One bill inbox. Unpaid bills report reviewed weekly. Approvals recorded. Recurring bills list current. No late fees in the last 3 months.
Fail looks like: Bills paid from email without checks. Duplicate payments. Late fees. A lapsed domain, hosting, or phone service.
Evidence to collect: Unpaid bills report, recurring bills list, three sample bills with approvals and payment proof, and any late fee charges.
