Stop Chasing Receipts: How Small Businesses Can Build an Accounts Payable Process That Actually Scales

Small business owners often feel like they are operating at the speed of light. There are customers to serve, employees to manage, vendors to pay, sales to close, and decisions to make every hour of the day.
When things are moving that fast, the back office is usually the first place where shortcuts happen.
A receipt gets lost. A vendor invoice sits in someone’s inbox. A contractor gets paid before a W-9 is collected. A credit card transaction hits the bank feed with no memo, no business purpose, and no backup. In the moment, none of these things feel like a crisis.
But over time, they add up.
Incomplete accounts payable records can create tax-time headaches, slow down month-end close, increase the cost of bookkeeping, and make life harder if your business ever goes through a financial statement audit, IRS or state tax audit, loan review, acquisition, or investor due diligence.
The good news is that this is fixable. You do not need a large finance department to build a clean accounts payable process. You just need a repeatable system, the right tools, and the discipline to stick with the process.
Accounts payable is more than paying bills
Many business owners think of accounts payable as simply “paying vendors.” That is part of it, but it is not the whole picture.
A strong accounts payable process answers five basic questions:
Who did we pay?
What did we pay for?
Was the expense approved?
Do we have the invoice, receipt, or supporting documentation?
Did it get recorded correctly in the accounting system?
When the answer to any of those questions is unclear, your business loses visibility.
That $312 charge on the company card may have been a legitimate software subscription, a client meal, a duplicate charge, or a personal expense. Without the receipt and memo, someone has to stop later and figure it out. Usually, that person is the owner, bookkeeper, accountant, or tax preparer, which likely is months after the transaction happened.
That is where the real cost shows up. It is not just the missing receipt. It is the time spent chasing it, explaining it, correcting it, and wondering whether the financial statements are complete.
Why documentation matters
For small businesses, missing receipts and vendor documents may not seem like a big deal. In the early days, the owner may know every vendor, every subscription, and every purchase by memory.
That changes as the business grows.
You add employees. You issue company cards. You use more software. You pay more contractors. You buy supplies from more vendors. You travel more. The number of transactions increases, but the owner’s memory does not scale with it.
The IRS expects businesses to maintain adequate records that support expenses, including documentation such as receipts, bills, canceled checks, and other evidence that shows the amount, date, place, and essential character of the expense. For travel, gift, and car-related expenses, IRS Publication 463 specifically discusses documentary evidence and notes exceptions, including expenses under $75 other than lodging. The same publication also makes an important point: a canceled check by itself does not prove business purpose.
That is why a “we can figure it out later” approach is risky.
At tax time, missing documentation can delay return preparation or require follow-up. During an audit, missing support can increase professional fees and create unnecessary stress. During financial statement preparation, incomplete backup can slow down reconciliations and make it harder to know whether expenses are recorded in the right period and category.
The cleaner your accounts payable process is today, the less expensive it is to clean up later.
The W-9 and 1099 problem
Vendor records are another area where small businesses often wait too long.
A common situation looks like this: you hire a contractor, pay them a few times, and only think about the W-9 in January when it is time to prepare 1099s. By then, the vendor may be slow to respond, the email may be outdated, or the payment details may be scattered across your bank account, accounting system, and inbox.
A better process is to collect vendor information before the first payment goes out.
That means your accounts payable workflow should include:
Vendor name and contact information
W-9 or tax information when applicable
Payment method
ACH, check, wire, or card details
1099 tracking status
Approval history
Invoice and payment history
For tax years beginning after 2025, the IRS increased the minimum threshold for certain information returns and backup withholding from $600 to $2,000, with inflation adjustments beginning in calendar year 2027. That said, 1099 rules can vary depending on the type of payment, entity type, payment method, and state requirements. Payments made through payment cards and certain third-party networks are generally reported by payment settlement entities on Form 1099-K.
The takeaway for business owners is simple: do not wait until January to find out whether you have the information you need.
A good accounts payable system should help you collect vendor information up front, track reportable payments throughout the year, and reduce the year-end scramble.
What a good small business AP process looks like
A scalable accounts payable process does not have to be complicated. In fact, the best systems are usually simple enough that the whole team can follow them.
Here is a practical structure for a small business:
1. Create one place for invoices
Invoices should not be scattered across five inboxes, text messages, and paper mail. Create one central place where vendor invoices go. That may be a dedicated email address, an AP inbox inside your software, or an invoice-forwarding workflow.
The rule should be clear: if a vendor invoice is not in the system, it does not get paid.
2. Collect vendor information before payment
Before paying a new vendor, collect the information needed to pay and report them properly. This includes payment instructions and tax documentation when applicable.
Modern AP tools can request this information electronically so the business owner is not manually emailing PDFs back and forth.
3. Require approval before money leaves the business
Even a very small business should have some type of approval process. For a solo owner, that may be one final review before payment. For a larger team, it may mean department approval, manager approval, and owner or controller approval above certain dollar thresholds.
Approvals protect cash flow and reduce surprises.
4. Capture receipts and memos as close to the transaction as possible
The best time to document a purchase is right after it happens.
If an employee buys supplies, pays for parking, books travel, or swipes a company card for a client lunch, the system should immediately request the receipt and business purpose. Waiting until month-end makes the process harder for everyone.
5. Sync to the accounting system
Accounts payable tools are most valuable when they connect directly to the accounting system. Once the receipt, memo, vendor, category, and approval are attached, the transaction can flow into the books with less manual cleanup.
That makes reconciliation easier and gives the owner more confidence that expenses are complete.
6. Review exceptions monthly
The goal is not perfection. The goal is to catch issues quickly.
Each month, review missing receipts, uncategorized transactions, unpaid bills, duplicate vendors, stale invoices, and any payments missing W-9 or 1099 information. A 10-minute monthly review is much better than a 10-hour cleanup project at year-end.
Tools that are available
The good news is that small businesses no longer need enterprise-level accounting software to build a strong accounts payable process.
There are several financial technology companies that tackle this issue directly. Two of the most common options are Ramp and Brex. Both combine spend management, corporate cards, bill pay, invoice workflows, approvals, and accounting integrations in one platform.
Ramp Bill Pay, for example, is an AI-powered accounts payable solution that can capture invoice details, route bills through approval workflows, pay vendors by ACH, card, check, or wire, and sync with accounting systems such as QuickBooks, NetSuite, and Sage Intacct.
Ramp also offers a free tier with core Bill Pay features. Ramp can also request payment and tax details from vendors, helping reduce the manual follow-up that often happens around W-9s and vendor onboarding.
Brex offers a similar category of tool, with bill pay features designed to import invoices, capture itemized details with AI, route approvals, pay by card, ACH, check, or wire, and sync AP data with accounting systems. Brex’s support documentation also describes bill pay policies that can customize approval chains and dynamically route bills based on attributes such as amount and vendor.
These platforms are not just for large companies. They can be especially helpful for small businesses that are growing quickly, adding employees, paying more vendors, or trying to move away from paper-heavy processes.
How Pathfinder uses Ramp
At Pathfinder, we use Ramp for our own expense and accounts payable needs. It has allowed us to keep our internal process simple, clean, and scalable. Also, full disclosure, we are a Ramp partner.
When someone invoices us, the invoice can be emailed or forwarded to a Ramp-provided AP email address. From there, we can review the bill, approve it, and pay the vendor by the appropriate method. If vendor payment or tax information is needed, the system can help collect those details electronically instead of relying on a long email thread.
For a very small business like us, the approval process is simple. One person may review and approve bills. As the business grows, additional approval layers can be added so department heads, managers, or owners approve expenses based on amount, vendor, or category.
We also use Ramp’s charge card features because many of our expenses are paid online. When a card transaction occurs, the team can be prompted to submit a receipt and memo via email or even text. Ramp’s Gmail or Outlook integration can automatically capture and match receipts from inboxes, which reduces the need for employees to manually upload receipts.
This matters because the easier the process is, the more likely people are to follow it.
We can issue cards with controls, create spend programs, and limit how cards are used. That means a junior employee can have access to a card without having unlimited spending authority. A card can be used for a specific vendor, a specific type of purchase, a travel need, or a one-off expense.
For our business, this has reduced accounts payable and expense management to a few minutes a month. Once receipts and memos are collected and matched to transactions, the data can be pushed into the accounting system. Reconciliation becomes easier, and we have more confidence that expenses are recorded with the backup we need.
Why this matters before you “need” it
Many small business owners wait until there is a problem before they improve accounts payable.
They wait until tax time is painful.
They wait until the bookkeeper is asking too many questions.
They wait until an employee makes an unauthorized purchase.
They wait until a vendor payment gets missed.
They wait until an audit, bank request, or due diligence process forces them to produce documentation.
By then, the cleanup is harder.
A strong AP process is not just about compliance. It is about control. It helps you know what you owe, what you spent, who approved it, where the backup is, and whether the books reflect reality.
That kind of clarity helps business owners make better decisions.
Signs your business is ready for an AP tool
You may not need a full accounts payable platform on day one. But you should start looking at better tools if any of these sound familiar:
You regularly chase employees for receipts.
Vendor invoices are sitting in multiple inboxes.
You are not sure which vendors need W-9s.
You spend too much time categorizing expenses after the fact.
You have employees using personal cards and waiting for reimbursement.
You do not have clear spending limits.
Your month-end close takes longer than it should.
You are planning for growth, financing, a future audit, or a potential sale.
Your accountant keeps asking for missing backup.
The right system can save time now and prevent bigger problems later.
Software helps, but the process matters most
A tool like Ramp or Brex can be a game changer, but software alone does not create a clean process.
You still need to decide:
Who approves bills?
What dollar amounts require additional review?
Which vendors can be paid by ACH, check, wire, or card?
What receipt rules will employees follow?
What memo detail is required?
How should expenses be coded?
Who reviews missing documentation each month?
How will W-9s and 1099 tracking be handled?
That is where Pathfinder can help.
We work with small business owners to design accounting processes that are practical, scalable, and easy to maintain.
