If you’re evaluating AP software, it’s very likely that you find your current workflow insufficient, error-prone, or simply not as effective as you would like it to be. And as you are comparing tools, it may be safe to say that the real thing you are looking for is not a handsome and heavy “features list”rather, it’s control you are seeking. You want something that tells you things like where the invoices come in from, who approves payments, how money goes out and whether compliance is handled properly, because no business likes last-minute scrambles at year’s end when returns start becoming due.
AvidXchange, BILL, and Zenwork Payments all automate accounts payable. But they are built with different priorities and so there is no “one-size-fits-all” solution.
Continue reading to know the major differences and key features of leading AP solutions and which automated AP software is right for you.
What does AvidXchange do?
AvidXchange is an accounts payable (AP) tool that helps businesses handle bills and vendor payments online. It’s used mostly by mid-sized companies, especially those that are in real estate, construction, HOA management, or healthcare.

AvidXchange also has different modules, through which it does different things.

What Does BILL (Bill.com) Do?
BILL (formerly known as Bill.com) is known for its diverse suite of payment options built to maintain speed, cost, and international payments support. It’s good for SMBs who are looking to digitize their manual processes and get support for cross-border payments. BILL majorly focuses on simplifying everyday manual AP tasks like data entry, invoice payment, approval workflow, and digital payment methods.
Furthermore, BILL also has AR functions that allow a business to send invoices and collect payments from vendors digitally. One of the biggest advantages of using BILL is its support for major ERP and accounting software like QuickBooks, Xero, NetSuite, etc., which makes sure that all financial records are up-to-date, and you can also pay vendors with multiple payment methods like ACH, virtual cards, and wire transfers (for international payments) from one unified dashboard.

- Essentials: $49/user/month
- Team: $65/user/month
- Corporate: $89/user/month
- Enterprise: Custom
What Does Zenwork Payments Do?
Zenwork Payments is a cloud-based automated AP solution. The system is built around simplifying vendor onboarding, role-based access control, and generating 1099-payments-ready data. The key difference between Zenwork Payments and the other two solutions mentioned above is their workflow order. While most platforms treat tax compliance as a separate year-end activity, Zenwork Payments is built on a compliance-first approach.
Where it wins for most SMBs and mid-to-large-sized entities alike is in how it simplifies vendor onboarding, invoice processing, payment approvals, and payments while also providing built-in 1099 workflows that stay up to date with vendor records and payment history.
Pros
- Dedicated vendor portal for self-onboarding
- W-9 collection and real-time TIN matching
- Auto-drafts 1099-NEC/MISC and e-files via Tax1099
- Bulk vendor imports and bulk payment scheduling via Excel or CSV
Cons
- Organizations not focused on compliance may find some features to be “too much”
- Currently focused only on AP AR workflows are yet to go live
Pricing
- Zenwork Payments starts at $19.99/month per payer, plus $2 for each billable vendor you pay monthly.
Comparing Key Features: AvidXchange vs Bill vs Zenwork Payments
To make your research easier, here’s AvidXchange vs Bill vs Zenwork Payments at a glance:
What you’re comparingAvidXchangeBILL (formerly Bill.com)Zenwork Payments
| What you’re comparing | AvidXchange | BILL (formerly Bill.com) | Zenwork Payments |
|---|---|---|---|
| What it’s mainly built for | Handling lots of invoices plus approvals, often in PO-heavy setups | General AP automation (and also AR for teams that need both) | Paying vendors and contractors with compliance built in (1099s, W-9, and TIN) |
| Best fit if… | You’re replacing a paper-heavy process and need a stronger invoice workflow | You’re an SMB or mid-market team that wants a well-known “all-around” AP tool | You pay many vendors and/or contractors and want cleaner year-end 1099 work with tighter payment control |
| Vendor onboarding | Usually set up during implementation and synced with your accounting/AP system | You manage vendor records in BILL and/or sync them from your accounting system | Vendors can onboard themselves through a vendor portal, so there is less chasing around for info |
| Approvals | Invoice approval workflows with multiple steps | Configurable approval workflows with audit trails | Payment approvals with role-based controls (that pre-determine who can approve what before money goes out) |
| How you can pay | Virtual card, AvidPay Direct (enhanced direct deposit), and checks | Multiple payment options (ACH, cards, checks, wires, etc.) | ACH, FastPay ACH, and checks |
| 1099 support | Basic tracking | Built-in 1099 e-filing | Native W-9 collection with real-time TIN Match and 1099-ready workflows (generating and filing through Tax1099 integration) |
Choosing the Best AP Automation for Your Team
AvidXchange can make sense for teams that rely heavily on structured purchase order workflows and want to replace a paper-heavy AP process with a more digitized system. So if you’re a mid- to large-sized organization processing a high volume of invoices, but don’t need much focus on compliance, and basic tracking will do, you can opt for AvidXchange.
BILL, on the other hand, may seem to be more suitable for businesses that make frequent international payments. And it’s clear why with multi-currency support, it’s built for teams that need broader global payment flexibility.
However, if most of your payments are domestic and you care deeply about compliance, Zenwork Payments stands out. It works well for growing organizations that need a system that can scale and is particularly useful if you pay many vendors or contractors, want a simpler onboarding process, and need built-in support for 1099 compliance, W-9 collection, TIN matching, and stronger control before payments go out.
FAQs
1. If we compare AvidXchange vs BILL AP automation, which is better for my mid-market company?
It partly depends on what you define as “mid-market” and mostly on what your company’s core needs are. AvidXchange is usually the better fit when you process high invoice volume and need more structured AP controls. On the other hand, BILL is a better choice if you want a broader, simpler AP hub that’s easier to run day to day.
2. If we compare Zenwork Payments vs BILL for 1099 vendors, which one will reduce my 1099 chaos?
Zenwork Payments is designed to be an end-to-end workflow, so if your biggest pain points are W-9 collection, TIN accuracy, and keeping vendor and payment records clean for 1099s throughout the year, Zenwork Payments will likely be more suitable than BILL.
3. What should I prioritize in vendor onboarding and AP automation tools?
For AP automation bundled with vendor onboarding, prioritize a smooth, clean vendor onboarding process, strong payment approvals, a reliable, preferably 2-way accounting sync, and an audit trail that reduces rework and prevents errors before tax season.
4. How should I compare the features of AvidXchange and BILL?
When comparing the features of two or more tools, start with your core workflows like invoice intake, approvals, payments, and accounting sync, and then look at the factors of differentiation to see which product handles your most common exceptions with the least manual effort.
5. What’s the best “AP software for invoice, vendor, and tax workflows”?
There isn’t a single “best” tool; the best choice for your team is the one that matches your volume, control requirements, and compliance needs while simultaneously reducing ongoing cleanup and manual work.
Final Thoughts
As already established fairly well, there is no one best AP automation software because the right choice for your team is completely dependent on the issues you are facing with your current workflow. Ask what’s slowing you down today: Is it invoice volume, international payments, vendor compliance, or something else that a particular AP automation software can help solve?
Before deciding, review your current AP workflow. Look at where errors happen, where delays build up, and where compliance risks show up or are most likely to. Then, with that clarity, you will be able to make a much better decision.
