A delayed customer payment, a higher payroll, or an unexpected repair can leave you unable to pay every bill at once. When that happens, paying whoever calls first, or avoiding vendors altogether, only makes things worse. The better approach is to prioritize payments based on risk, operations, and the relationships that matter, then communicate early when timing needs to change.
If you read our last post on why your bank balance doesn’t tell you what you can actually spend, this is the next piece of that puzzle: once you know what your business owes, here’s how to decide what gets paid first.
Start With an Accurate Accounts Payable Report
Before deciding which bills to pay, run the Accounts Payable Aging report in QuickBooks Online. It should show who you owe, how much, when each bill is due, and how long overdue balances have been sitting. That report is only reliable if bills are entered correctly. A vendor invoice sitting in an inbox, on a desk, or in a truck won’t show up on it.
Before you build a payment plan, confirm that all known vendor and subcontractor bills have been entered, due dates are correct, there are no duplicates, vendor credits have been applied, disputed charges are flagged, and payments already made are recorded properly. You can’t prioritize what you can’t see.
Do Not Pay Bills in Random Order
When cash is tight, it’s tempting to pay whoever calls first or whatever invoice happens to be on top of the pile. That can leave too little for payroll, taxes, materials on an active job, or a supplier your operation depends on. Instead, sort bills into three groups: critical and legally required obligations, payments that keep revenue producing work moving, and payments that can be scheduled or negotiated. That framework keeps you making decisions instead of just reacting.
Priority 1: Protect Critical and Legally Required Obligations
Some payments need immediate attention because missing them creates legal, financial, or operational consequences: payroll, payroll tax deposits, sales tax, required insurance, rent or mortgage, secured loan payments, essential utilities, and court ordered payments. These shouldn’t be pushed back just because another vendor is applying more pressure.
Collected payroll taxes and sales tax deserve special care here. That money may be sitting in your bank account, but it was never really yours to spend on an ordinary cash shortage. Confirm you can meet these obligations before you pay standard vendor invoices.
Priority 2: Protect Payments That Keep Revenue-Producing Work Moving
Next, identify the bills that directly affect your ability to complete jobs, invoice customers, and collect revenue: materials for active jobs, key subcontractors, equipment rentals, permits, fuel, job specific deliveries, and critical repairs. Ask whether delaying a payment would stop work, prevent invoicing, miss a customer deadline, or put your credit terms at risk. A supplier or subcontractor often deserves priority because the payment protects both current revenue and a relationship you need. The goal isn’t to pay every job related bill immediately. It’s to protect the ones that keep profitable work moving.
Priority 3: Schedule or Negotiate Flexible Payments
Some payments have more flexibility: bills not yet due, nonessential subscriptions, discretionary purchases, vendor balances with longer terms, optional upgrades, owner distributions, and anything covered by an approved arrangement. Don’t pay a bill early just because the cash happens to be there today. If something is due in 30 days, paying it on day 10 might not be the best use of cash if payroll is right around the corner. Use the terms the vendor gave you. The goal isn’t to wait until the last possible moment either. It’s to schedule payments on purpose.
Separate Disputed Bills From Cash Flow Decisions
A disputed or incorrect bill shouldn’t just sit in Accounts Payable. It might involve a wrong quantity, duplicate billing, incomplete work, a price that doesn’t match the agreement, or missing credits. Contact the vendor promptly, document the issue, and when appropriate, pay the undisputed portion by the due date. That shows good faith while the rest gets resolved. Ignoring the whole invoice can turn a manageable disagreement into a damaged relationship.
Use Vendor Terms Intentionally
Vendor terms give you an agreed window for payment, and used well, they help match your outgoing cash with completed work and customer collections. Repeated late payments, though, can lead to reduced credit limits, shorter terms, cash on delivery requirements, service holds, or a damaged relationship. Use those terms as part of a planned process, not as a substitute for one. An early payment discount can be worth taking, but not if it leaves you short for payroll, taxes, or job costs. Weigh the savings against the cash pressure it creates.
How to Communicate When a Payment Will Be Late
When a payment may be delayed, contact the vendor before the due date. Don’t wait for them to call you. Early communication often opens up more options, like moving the due date, accepting a partial payment, or splitting the balance into installments. Keep the conversation brief, direct, and realistic. Something like: “We are expecting a customer payment later than planned, and I wanted to reach out before your invoice becomes overdue. We can pay $3,000 on Friday and the remaining $2,000 by July 24. Would that work for you?”
Before you make that promise, confirm what you can realistically pay, where that cash is coming from, whether that source is dependable, and what else is due before that date. A missed promise often damages trust more than the original delay does. Vendors usually understand an occasional tight month. What damages the relationship is being surprised, ignored, or given promises that don’t get kept.
Document Revised Payment Arrangements on the Bills
Keep the original date, amount, and due date intact in QuickBooks, then document the revised arrangement directly on the bill it applies to: the date of the conversation, who approved it, the new amount and date, any partial payment schedule, and any reference to supporting email or written confirmation. This keeps your Accounts Payable history accurate while making the arrangement easy to find later. Everything stays connected to the bill it affects.
Create a Weekly Bill-Payment Schedule
A weekly schedule keeps you from making decisions one invoice at a time. Confirm available cash after protecting payroll, taxes, and your minimum reserve. Review what’s due, overdue, or coming due. Identify payments tied to jobs you can complete and invoice this week. Prioritize critical obligations and the payments that keep active jobs moving. Schedule flexible payments according to terms. Reach out to vendors where a revised arrangement might be needed. Then approve and document the final plan. This creates a controlled process instead of reacting to emails and phone calls all week long.
Five Common Accounts Payable Mistakes
Paying whoever complains the loudest, since the most persistent vendor doesn’t automatically have the highest priority bill. Entering bills late, which makes the Accounts Payable report incomplete and creates surprise obligations. Paying every bill early, which can drain cash you need for payroll, taxes, and active jobs. Promising payment based on an uncertain customer invoice, since an open invoice isn’t dependable cash until it’s actually collected. And using vendor credit to hide weak pricing, since longer terms might delay the impact of an unprofitable job, but they don’t fix the underlying problem.
Recognize When the Problem Is Deeper Than Timing
A profitable business can still hit a temporary cash shortage. You may have completed profitable work and still be waiting on customer payment, or you may have paid for labor and materials before collecting the related revenue. That’s a timing problem. But if the same bills are a struggle every single month, the issue may run deeper, in pricing, job costs, collections, debt, overhead, or owner withdrawals. A payment schedule can manage a short term gap. It can’t fix an unprofitable or poorly managed operation on its own.
Prioritize Bills With a Plan, Not With Panic
When cash is tight, the goal isn’t to pay the greatest number of bills. It’s to protect the business while still treating vendors fairly. Start with an accurate Accounts Payable report. Protect critical obligations. Keep revenue producing work moving. Schedule flexible payments intentionally. Communicate early and document revised agreements on the affected bills. A thoughtful Accounts Payable process can keep a temporary cash problem from turning into a damaged vendor relationship, a frozen account, or a much bigger crisis.
Knowing which bills to pay first is a math problem. Knowing how to lead your business through a tight cash month with confidence instead of panic is a mindset problem. Beyond The Numbers helps you build the financial leadership skills to make steady decisions even when cash is tight.
