Accounts Payable Workflow
Updated: 2026-03-04
A clean accounts payable workflow: capture vendor bills, approve, schedule payments, avoid late fees, and keep cash flow predictable.
- AP is the process of turning vendor invoices into controlled payments.
- Enter bills promptly so cash planning is accurate.
- Use approvals and payment runs to prevent mistakes and duplicate payments.
- Review AP aging regularly to avoid late fees and vendor issues.
Accounts payable (AP) is how you control outgoing cash. A clean AP workflow keeps vendor relationships healthy and prevents cash surprises.
The AP workflow
1) Capture bills consistently
Bills typically arrive via:
- email PDF
- paper invoice
- vendor portal
The rule: every bill gets recorded even if you plan to pay soon.
2) Enter the bill promptly
When you enter the bill, include:
- vendor
- bill date
- due date
- amount
- category/account
- memo / job / project reference (if applicable)
Prompt entry is the foundation of predictable cash flow.
3) Approve bills (optional but recommended)
Approval prevents:
- paying the wrong amount
- paying the wrong vendor
- duplicate payments
- unauthorized purchases
Even a simple “owner approves weekly” process is a big upgrade.
4) Schedule payments
Most businesses pay in batches (“payment runs”):
- weekly (common)
- twice monthly (common)
- as-needed (small volume)
Choose a rhythm that matches your cash flow.
5) Pay and record the payment
When you pay, record:
- date
- method (ACH, check, card)
- cash/bank account used
- which bills were paid (full or partial)
6) Review AP aging
AP aging answers:
- what’s due now
- what’s overdue
- what’s coming due soon
Review it at least monthly. Weekly is better if volume is high.
Common mistakes
- Paying bills without recording them first
- Recording everything as “expense” even when unpaid
- Not tracking partial payments
- Losing bills and discovering them after they’re overdue

FAQ
What’s the difference between an expense and a bill?
An expense is paid immediately. A bill is something you owe and will pay later.
How often should I run bill payments?
Most businesses do weekly or twice-monthly payment runs, depending on volume and cash flow.
What’s the #1 AP control?
Entering bills quickly and reviewing AP aging before paying. If bills aren’t recorded, cash planning is guesswork.
