Which tool fits which team?

There is no single best tool; the right one depends on your size, your accounting system and which part of the job is slow.

By situation

Under about 20 bills a month, one approver: Your accounting system on its own (see below).
Paying vendors is the main job: Melio or Ramp, both with free plans.
Approvals are the gap on Xero or QuickBooks Online: ApprovalMax.
An accountant or bookkeeper does the books: Dext or Hubdoc.
Purchase orders, deliveries and several approvers: Aequo AP (Starter for 2-way matching, Growth for 3-way).

When your accounting system is enough

Many small businesses do not need an AP tool yet. QuickBooks Online and Xero both capture bills and pay them; add software when approvals, purchase orders or volume make that manual.

QuickBooks Bill Pay is included; Premium is $15 a month and Elite, which adds bill approval workflows, is $45 a month. [source: Intuit, QuickBooks Bill Pay]
Xero’s Smart Document Capture creates draft bills from uploaded or forwarded bills on every US plan. [source: Xero US pricing plans]
Zoho Books includes purchase approvals from its Professional plan. [source: Zoho Books US pricing]

Signs you have outgrown it: bills wait in someone’s inbox for approval, the same invoice gets entered twice, or invoices are paid without being checked against what was ordered and delivered.

Known limitations of each tool

Every tool here has gaps, Aequo AP included. Each limitation below comes from the vendor’s own pages, or from what those pages leave out.

Melio: A payments tool: no PO matching is mentioned, and the free Go plan is one user without custom approvals [source: Melio pricing]
Ramp: The Plus platform fee is not published, and Ramp-issued POs with 3-way match need the Procurement add-on [source: Ramp pricing]
BILL: Priced per user: on Essentials and Team every approver is billed as a full user, and 3-way matching is only on the custom-priced Enterprise plan [source: BILL pricing]
ApprovalMax: Works only with Xero, QuickBooks Online and NetSuite, and bill-to-PO matching needs the Advanced plan or higher [source: ApprovalMax integrations]
Dext: A capture tool: its pricing page describes no purchase orders or matching, and extraction stops at the monthly document limit [source: Dext business pricing (US)]
Hubdoc: Syncs only to Xero and QuickBooks Online, and its pages describe no approvals, purchase orders or matching [source: Hubdoc pricing]
Yooz: No US price is published, and which edition includes PO matching and payments is not stated [source: Yooz pricing (US)]
Aequo AP: Does not pay vendors yet (coming soon); Oracle NetSuite and Sage Intacct are early access only; no PO approvals or procurement; prices are in US dollars

What it costs: a worked example for 500 invoices a month and 5 people who approve them

At small-business volumes, free payment plans and capture tools cost least; per-user plans climb with every approver, and a flat plan only pays off once matching and several approvers are involved.

Monthly subscription cost for 500 invoices a month and 5 people who approve them, from published prices
Tool	Monthly cost at this volume
Melio	$25 (Core), $55 (Boost) or $80 (Unlimited) a month, plus $10 per extra user on Core and Boost and ACH fees beyond the plan allowance [source: Melio pricing]
Ramp	$0 on Free; $75 a month on Plus ($15 × 5 users) plus a platform fee that is not published [source: Ramp pricing]
BILL	$325 a month on Team ($65 × 5 users), or $445 on Corporate for purchase orders ($89 × 5), plus payment fees such as $0.59 per ACH payment [source: BILL pricing]
ApprovalMax	Not shown in the page text; priced per organisation, and PO matching needs Advanced or Premium [source: ApprovalMax for QuickBooks Online pricing]
Dext	Not published at this volume: the listed $25.21 a month (billed annually) covers 250 documents and 5 users [source: Dext business pricing (US)]
Hubdoc	$12 a month on its own (capture only) [source: Hubdoc pricing]
Yooz	Not published (priced by document volume) [source: Yooz pricing (US)]
Aequo AP	$699 a month on Growth (up to 1000 documents, 3-way matching), the same for 5 approvers or 50

List prices only, before discounts, taxes and implementation. “Quote only” and “not published” mean the vendor does not publish a price; ask for one at your volume. Payment fees apply only if you pay vendors through the tool.

When is Aequo AP not the right fit?

In these cases another tool on this page, or your accounting system on its own, is the better choice.

You enter a handful of bills a month and one person approves them. Your accounting system's own bill features are probably enough; Aequo AP's Starter plan covers up to 250 documents a month.
You want one tool that also pays vendors today. Aequo AP vendor payments are coming soon; until then you pay approved bills from your accounting system or bank.
You only need receipts and bills captured into your books. Dedicated capture tools cost a fraction of Aequo AP's $199-a-month Starter plan.

Frequently asked questions

What is the best accounts payable software for small business?

For a small business that mainly pays bills, Melio and Ramp have free plans and BILL adds approvals at a per-user price; Dext and Hubdoc capture bills cheaply, and ApprovalMax adds approvals to Xero or QuickBooks Online. Aequo AP fits small teams that need invoices matched to purchase orders, with unlimited users from $199 a month.

What is the cheapest accounts payable software for a small business?

Ramp and Melio have free plans (Melio Go is one user), Hubdoc is $12 a month or included with Xero, and Dext starts at $25.21 a month billed annually. These cover payments or capture, not purchase-order matching.

Do small businesses need AP automation?

Not always. If one person enters and approves a few bills a month, QuickBooks Online or Xero on their own are usually enough. AP automation pays off when several people approve, you use purchase orders, or volume makes keying and checking bills slow.

What is the difference between AP automation and bill pay?

Bill pay moves the money: it schedules payments, sends ACH and checks and records them. AP automation decides what should be paid: it captures each invoice, matches it to the purchase order and receipt, routes approvals and clears exceptions before payment. Many teams use both.

Which small business AP software works with QuickBooks Online?

Melio, Ramp, BILL, ApprovalMax, Dext, Hubdoc, Yooz and Aequo AP all name QuickBooks Online or QuickBooks among their integrations on the pages we checked (2026-10-30).

Automate matching, approvals and exception handling

Aequo AP captures invoices, matches them to purchase orders and receipts, routes approvals and flags duplicates and exceptions, then syncs with QuickBooks Online, Xero, FreshBooks, Zoho Books or Business Central.
