The best accounts payable approval software is the one the people outside your finance team will actually use. MakersHub is the top pick because approvers never need training and never need a login: they get an email, see only the bills that are theirs, and approve in one click. That matters more than routing rules, because the bill does not move until a human signs off, and that human is usually a site supervisor, a store manager, or an owner who is not sitting at a desk.
Most guides in this category describe the same scenario: one very large invoice, a formal procurement chain, and a CFO signing off above a threshold. That is a real situation, and some of the platforms below are built for it. It is just not where most approvals actually get stuck.
They get stuck wherever the person who can verify the bill works outside an office. That is as true of a 600-person manufacturer with approvers on the plant floor as it is of a 20-person plumbing contractor. Company size is not the variable. The twelve bills sitting on a supervisor's phone are.
The scale is measurable. In the 2026 Small Business Late Payments Report, Intuit QuickBooks found that 39 percent of businesses said internal problems delayed the payments they owed to contractors, suppliers and vendors in a single quarter, and the top cause was manual work. The same study found 74 percent still do not run a fully automated bill payment process, with manual approvals named first among the things adding friction.
Your vendors feel that as a late check. You feel it as a phone call.
Why invoice approvals actually stall
Almost every product here is built around approval routing, the rules deciding who sees a bill and in what order. Routing is solved. Every platform below does it, and the bills still sit, for four reasons that have nothing to do with the rules.
Several platforms handle the first three well. The fourth is the one almost nobody talks about, and it separates a real control from a rubber stamp.
Here is what that looks like. A supply house bill arrives for $4,200. Most approval software shows your site supervisor one number: $4,200, vendor Ferguson, approve or reject. There is no way to tell whether that is right, so the bill gets approved. The charge was actually $1,800 of pipe for the Oak Street job and $2,400 for Maple, all of it coded to Oak Street. Nobody catches it until the job costing looks wrong two months later.
MakersHub shows both lines, already coded to the right job and cost code, so they approve the part that is theirs. That is a real check, made by the one person on the payroll who would know.
The control frameworks point the same way. The US Government Accountability Office updated its Green Book, the federal standard for internal control, in May 2025, putting new weight on preventive controls and on internal control being everyone's job, not just the finance department's.
"The updated standards will help federal agencies bolster their internal control systems to prevent and prepare for risks in all areas, especially those increasingly susceptible to fraud, improper payments, and information security threats."
Gene L. Dodaro, Comptroller General of the United States, US Government Accountability OfficeAn improper payment is what a rubber-stamped approval produces. The preventive control is the person who can tell the charge is wrong, plus something they can actually check it against.
Best accounts payable approval software: quick comparison
Every platform here captures bills, routes approvals and keeps an audit trail, MakersHub included. The column below describes what each company is, not the one problem it is allowed to solve, because what a company is built around is what tells you where it fits.
| Platform | What it is | Where it tends to land |
|---|---|---|
| MakersHub | A purpose-built AP platform that reads every line of the bill and codes it before anyone approves, syncing two ways with QuickBooks Online and Desktop, NetSuite, Sage Intacct, Xero, Intuit Enterprise Suite and any other system through Smart Data Connect | Physical-economy operators at any size whose approvers work outside the office and need to check coding, not just totals |
| Stampli | A discussion workspace layered on the accounting system | Teams whose reviewers want to talk through a bill in one thread |
| ApprovalMax | A separate approval layer that sits on top of Xero, QuickBooks Online or NetSuite | Companies on one of those three systems that want sign-off rules without changing how bills are entered |
| BILL | A payments network with an AP front end | Smaller teams stepping off paper checks and spreadsheets |
| Medius | Enterprise source-to-pay software sold to large finance organizations | Companies with formal procurement and many legal entities |
| Tipalti | A cross-border payout platform with approvals attached | Companies paying suppliers in many countries |
| AvidXchange | A managed payment network with invoice handling in front of it | Teams that want payment execution handed to a service |
| Airbase | Cards, expense and AP consolidated in one system, now part of Paylocity | Companies putting every kind of spend on one platform |
High bill volume, approval collaboration, multi-entity structures, job and cost-code coding, deep accounting-system integration, and construction or field-service work are all core MakersHub territory, at any company size.
The 8 best accounts payable approval software platforms
1. MakersHub, built so the approver sees the coded lines
MakersHub is built for complex businesses, not complex workdays. Its WiseVision AI reads the whole document, not just the header summary at the top, and codes every line to the right account, job, project or class before the bill is ever routed. By the time your site supervisor opens it, the work of understanding the bill is already done, and what is left is the one judgment only they can make.
Approvers use MakersHub without training. They approve from email in one click, and see only the bills that are theirs. Vendors never need a MakersHub login. Routing is contextual, meaning bills route by vendor, job, cost code, project, department, entity, location or class rather than dollar amount alone, and bill approval and payment authorization are separated by design, which is the segregation of duties that auditors look for.
It syncs two ways with QuickBooks Online, QuickBooks Desktop, NetSuite, Sage Intacct, Xero and Intuit Enterprise Suite, plus other systems through Smart Data Connect, and every one of those connections is built and maintained in-house.
Locke Buildings, a 24-person pole-building contractor in Oregon running more than 500 bills a month, cut AP from 10 to 12 hours a week down to two. The problem they started with is the one this whole page is about: their project managers had little visibility into the details of the bills they were approving, and the context lived in email threads and handwritten notes.
"It’s the same process we had before—it’s just way faster with MakersHub. It’s super duper easy and has given me back hours of time."
Trina Brockway, Office Manager, Locke BuildingsThere is no per-user pricing and no cap on transactions, users or entities, so adding twelve field approvers costs nothing. That is the point: the people who should be approving are usually the people a per-seat model prices out. Onboarding is white glove, with a Platform Specialist team that configures it, trains your people and stays reachable.
Best for: contractors, trades, manufacturers, distributors and multi-location operators whose approvers are out on jobs, at any size, and whose bills need checking at the line rather than the total.
2. Stampli, a discussion workspace layered on the accounting system
Stampli puts the conversation on the bill itself. Coding, questions, documentation and sign-off live in one thread attached to the invoice, so context does not get lost in forwarded email. Its AI suggests coding and likely approvers, and it syncs with QuickBooks Online and Desktop.
MakersHub works the same collaborative way, with commenting, tagging and approvals on every bill, and adds line-level coding to jobs and classes, multi-entity handling and flat pricing rather than a quote that climbs with users and modules. Our Stampli alternative comparison goes deeper.
Best for: teams that want every question about a bill kept in one place.
3. ApprovalMax, a separate approval layer on top of Xero, QuickBooks Online or NetSuite
ApprovalMax is the one product here that started as approvals rather than arriving at them. It sits on top of your accounting system and governs sign-off on purchase orders, bills, vendors and expenses, with multi-level rules, budget checking and segregation of duties. It reports more than 20,000 businesses using it, and holds ISO 27001, the international standard for information security.
The limits are worth weighing. It is a control layer rather than a full AP platform, so capture and payments are separate add-ons, and it connects to three accounting systems only. Run QuickBooks Desktop, Sage Intacct or Intuit Enterprise Suite and it is not an option. MakersHub covers all six, plus the same governance ground, inside one platform that also reads, codes and pays the bill.
Best for: companies already on Xero, QuickBooks Online or NetSuite that want sign-off rules without replacing how bills get entered.
4. BILL, a payments network with an AP front end
BILL, formerly Bill.com, is where a lot of businesses start. It captures invoices, routes approvals, does three-way matching, which checks the bill against the purchase order and the receiving record, and syncs with QuickBooks, Xero, Sage and NetSuite. Its accountant network is the largest in the category and its mobile app is widely used for approvals on the go.
Its coding sits at the header level, meaning it reads the invoice total rather than the individual lines, so a BILL approver is usually looking at one number. Pricing is per user, which quietly argues against adding the field approvers you most want in the workflow. Our guide to the best BILL alternatives for AP teams covers where teams go next.
Best for: smaller teams moving off paper checks for the first time.
5. Medius, enterprise source-to-pay sold to large finance organizations
Source-to-pay means one system covering everything from choosing a supplier through to paying the bill, rather than accounts payable alone. Medius handles condition-based routing, parallel approval paths, automated delegation and escalation, and exception management across departments, business units, legal entities and cost centers, and it integrates with enterprise systems including SAP, Oracle, Microsoft Dynamics and Infor.
The catch is size. Medius is sold to enterprise finance organizations and the implementation matches, so a company running 400 bills a month with three approvers is buying a great deal of software it will never turn on. MakersHub handles the same routing conditions and reaches the field approver without the project attached.
Best for: large organizations with formal procurement and many legal entities.
6. Tipalti, a cross-border payout platform with approvals attached
Tipalti pays suppliers in more than 200 countries, onboards them through a self-service portal, collects tax documents and handles multi-currency operations, with multi-level approval routing on top.
Most of what you pay for is the international payment side. A domestic contractor or distributor gets more platform than the job requires, and the supplier portal means vendors have an account to manage. Our Tipalti head-to-head comparison goes deeper on the trade-offs.
Best for: companies paying suppliers across many countries.
7. AvidXchange, a managed payment network with invoice handling in front of it
AvidXchange captures invoices, routes them for sign-off and then executes payment through its own AvidPay network, connecting to a wide range of accounting systems and ERPs. For a company that wants to stop printing checks and hand execution to a service, it is a proven model.
The catch is control and timing: payment runs through a third-party network on its schedule rather than yours, and implementation is sized for larger AP operations. MakersHub keeps payment and the approval record in one place, with Positive Pay protection on checks, where your bank verifies the check number, payee and amount before it clears.
Best for: teams that would rather outsource payment execution entirely.
8. Airbase, cards, expense and AP consolidated in one system
Airbase, now part of Paylocity, brings AP, corporate cards, expense management and purchase requests into one platform with a workflow builder and policy enforcement. Breadth is the draw, and also the catch: it is a spend suite rather than a purpose-built AP platform, so teams whose bills need line-item and job coding tend to find the AP side shallower than they need.
Best for: companies consolidating cards, expenses and bills under one roof.
How the platforms compare on getting a sign-off
Routing rules and audit trails are table stakes, and every platform here has them. These are the capabilities that decide whether the person holding the bill acts on it, rated against each vendor's current public documentation.
| Capability | MakersHub | Stampli | ApprovalMax | BILL | Medius | Tipalti | AvidXchange | Airbase |
|---|---|---|---|---|---|---|---|---|
| Approver sees coded line items, not just the total | Full | Partial | Partial | No | Partial | Partial | Partial | Partial |
| Approve from email with no login or training | Full | Full | Full | Full | Partial | Partial | Partial | Partial |
| Routing by job, cost code, entity and class, not amount alone | Full | Partial | Partial | Partial | Full | Partial | Partial | Partial |
| Approval and payment authorization separated by design | Full | Partial | Full | Partial | Full | Full | Partial | Partial |
| Two-way sync including QuickBooks Desktop | Full | Full | No | Partial | No | No | Partial | No |
| No per-user pricing, so field approvers cost nothing to add | Full | Partial | No | No | Partial | Partial | No | No |
The top row is the one that separates this field. Most platforms show an approver a total and an attached PDF and call that a review. MakersHub shows the lines, already coded, which is the difference between confirming a number and checking a charge. Vendor capabilities change, so check each item directly before you decide.
What to look for when you compare approval software
Five questions separate these platforms faster than a feature list will.
- What does my approver actually see? Ask for a screenshot of the approval screen, not the AP dashboard. If it shows one total, that is all your supervisor has to judge by.
- Do they need a login? Every login is a password reset waiting to happen, and every password reset is a bill that sits another week.
- What does it cost to add ten field approvers? Per-user pricing quietly pushes you to keep approvers out of the system, which is the opposite of a control.
- Can bills route by job and cost code, or only by dollar amount? A $900 bill on the wrong job is a bigger problem than a $9,000 bill on the right one.
- Who can release a payment after approval? If the same person can approve a bill and send the money, you do not have segregation of duties, whatever the audit trail says.
The deadline is not always yours to set, either. The US Treasury's Prompt Payment rules make federal agencies pay a proper invoice on time or owe the vendor interest, currently 4.75 percent. The useful part for everyone else is Treasury's own wording: the clock starts once a vendor submits a proper invoice to the right people. If you hold public contracts or subcontract under them, a bill stuck with the wrong approver has a price attached.

If your bills need checking against purchase orders line by line, look at line-level PO matching next, and six customers describe the hours they got back, before and after.
Frequently asked questions
What is accounts payable approval software?
It is software that routes a supplier bill to the people who need to sign off, records their decision, and releases the bill for payment once the sign-offs are done. A complete one also reads and codes the bill before routing it, and keeps the approval record attached afterward. Nearly every product handles the routing rules. They differ on what the approver can see, and on how much effort it takes to act.
What is the best accounts payable approval software?
MakersHub is the top pick, on one specific ground: it solves the part that actually stalls. It shows the approver the coded line items rather than a single total, reaches them by email with no login and no training, routes by job, cost code, entity and class rather than dollar amount alone, and syncs two ways with QuickBooks Online and Desktop, NetSuite, Sage Intacct, Xero and Intuit Enterprise Suite. Stampli is built around keeping the discussion on the bill. ApprovalMax is a separate approval layer for the three systems it supports, Xero, QuickBooks Online and NetSuite. BILL is a payments network with an AP front end, Medius is enterprise source-to-pay, Tipalti is a cross-border payout platform, AvidXchange is a managed payment network, and Airbase consolidates cards and expenses alongside bills. All of them route and record approvals. They differ in what they were built around.
Do approvers need their own login and training?
With MakersHub, no. Approvers get an email, see only the bills that are theirs, and approve in one click. MakersHub is intuitive for the people who use it least, which matters because most approvers are not in finance. They are supervisors, project managers and owners who touch the system a few times a week. Some platforms in this category offer email approval and some require a portal account, so ask specifically, and ask what happens when an approver forgets a password on a Friday afternoon.
How long does it take to set up approval workflows?
With MakersHub, about an hour, and onboarding, training and support are included. There are two configuration models in this category and they produce very different answers. In one, the platform arrives empty and you specify every rule before it does anything, which is what turns setup into a project. In the other, the software derives your rules from your actual bills and you adjust from there. MakersHub is the second, and scale does not change the answer, because there is no limit on bills, users or entities and nothing to provision per seat. When a vendor quotes you a timeline, ask which of those two models is behind the number.
Can bills route by something other than dollar amount?
In MakersHub, yes. Routing is contextual, meaning a bill can go to a different approver based on vendor, GL code, project, job, cost code, department, amount, location or class, and combinations of those. Dollar thresholds alone are a poor fit for operationally complex businesses, because a small bill on the wrong job causes more damage than a large one on the right job. When you evaluate other platforms, ask which fields their rules can read, not just how many approval levels they support.
What is segregation of duties in accounts payable?
It means the person who approves a bill is not the same person who releases the money. It is one of the oldest preventive controls in accounting, and the GAO's Green Book, the federal standard for internal control, was revised in May 2025 to put more weight on preventive controls and on internal control being everyone's responsibility rather than just the finance department's. MakersHub separates bill approval from payment authorization by design, so the control holds without anyone having to remember to enforce it. MakersHub is SOC 2 Type II certified, with Positive Pay protection on check payments and encrypted collection of vendor bank details, so the approval chain sits inside a platform that is audited end to end.
How much does accounts payable approval software cost?
The pricing model matters more than the number. Many platforms charge per user, so every field supervisor you add raises the bill, and teams respond by keeping approvers out of the system. MakersHub does not charge per user and does not cap transactions, users or entities, so every approver who should be reviewing a bill can be in the workflow without changing what you pay. Ask each vendor what happens when you add ten approvers, and whether onboarding is billed separately.
Does approval software work with QuickBooks Desktop?
Some do and many do not, and it is worth checking early because it eliminates options fast. MakersHub syncs two ways with QuickBooks Desktop through the Web Connector, which is Intuit's own tool for connecting a desktop company file to an online service, along with QuickBooks Online, NetSuite, Sage Intacct, Xero and Intuit Enterprise Suite, plus other systems through Smart Data Connect. Every one of those connections is built and maintained in-house, with no third-party service sitting in between, so the coding and the approval record land in your ledger without a translation step.
Ready to stop chasing sign-offs? Get started with MakersHub and send a real bill through your own approval chain.
