Specific Challenges Small Businesses Face & How AP Software Can Help

Small businesses face a range of unique challenges and problems stunt growth and stall efficiency. Unfortunately, many education resources tend to skip over these unique problems in favor of those faced by larger, enterprise-level operations. And why not? By comparison, SMB issues are small potatoes – but that isn’t the case if you’re a small business owner trying to navigate scale-specific issues on your own.

For some issues, though, implementing AP software goes a long way toward minimizing some of the more severe and crippling issues. Some of the issues that are devastating as you face them include:

1. Manual data entry and inevitable errors: AP software automates data capture, integration, and storage – ensuring its integrity and cutting down on user error.

2. Late payments and fees: By using automated scheduling within AP software, SMBs can stay on top of payment windows, avoid late payments, and even maximize early payment discounts.

3. Inefficient paper systems: Accounting is one of the few domains that paperless society goals have yet to fully penetrate; digitizing operations through AP software helps eliminate the need for excess paper, increases efficiency (especially for remote or dispersed teas), and is more eco-friendly.

Challenge #3: Vendor Management

Which Feature Sets Should Small Businesses Prioritize When Evaluating AP Software?

Your SMB’s needs are wide-ranging, so defining a strict set of features to fit all small business accounts payable software requirements isn’t useful. Instead, we’ll look at some common core components to demand from your accounts payable automation software:

  1. Automated invoice and payment management: This is the bare minimum, but seek to find how accurate, timely, and trustworthy the core automation features are.
  2. Integration: Small business accounts payable automation software needs to work for you and with you – not the other way around. Make sure your selected software isn’t overly restrictive to your existing systems.
  3. Security: Cyberthreats are a real and present danger, especially when it comes to virtual finance crimes. Make sure your – and your vendors’ – information is safe.
  4. Overseas payment management: If you work with international vendors, you know the struggle that managing foreign transactions can be. If it applies to your business, ensuring it helps with cross-border transactions can save a ton of time and headache.

Which Accounts Payable Software Integrations Are Most Valuable for Smaller-Sized Businesses?

Again, integrations are business dependent. But, like we said above, your AP automation software should work within your current ecosystem, rather than forcing staff to adapt. Common integrations to validate before committing include:

  1. Other accounting platforms
  2. ERP, if applicable
  3. Banks and banking platforms
  4. Procurement/inventory management tools
  5. Analytics tools – some offer in-house analytics, but if you have a preference, ensure it integrates.

[H3] What benefits does accounts payable software bring to small businesses?

Managing your accounts payable as a small business owner isn’t just a waste of valuable time – it’s costing real money in terms of misallocated resources while amplifying potential for error, no matter how diligent you are. You should also expect your accounts payable software to:

2. Better visibility into payables: Get real-time visibility into your payables — what is the status of an invoice, when a payment is due, who approved it, mode of payment, and more. This transparency helps in better cash management and ensures timely payments.

3. Enhanced vendor relationships: Schedule and make payments on time, every time, with automated reminders and scheduling features. Accurate data extraction prevents payment amounts or details errors, ensuring no hiccups in vendor payments. This fosters trust and builds better relationships with your suppliers.

4. Improved compliance and audit trails: Detailed transaction histories, 3-way matching, and other audit trail features make it easy to maintain compliance and prepare for audits. This also helps in detecting and preventing fraudulent activities.

5. Efficient cash flow management: Features like invoice approval workflows, payment scheduling, and real-time reporting enable accounts payable software to manage cash flow efficiently. It ensures that your business has the right amount of cash in hand at the right time — no late payments, missed discounts, or duplicate transactions.


Accounts payable software is gradually bringing enterprise-level accounting solutions to small businesses. By automating the full spectrum of AP processes—invoice capture, payment processing, vendor management, financial reporting, and more—these solutions are an important first step to streamlining streamlined operations. They save time and reduce human error rates while also providing insights into a business’s financial health through robust analytics and reporting tools.

As small businesses face increasing competition and complexity in their operations, the adoption of comprehensive AP software is not just a matter of convenience but an essential requirement.

Value from investing in accounts payable software are real and tangible, but the biggest benefit is time saved and put toward your real goals – growth and quality.
