Moss and ApprovalMax both reduce manual work around finance operations, but their focus and product design are different. This comparison looks beyond the headline features to show where the two platforms overlap, where they separate, and what each approach is designed to achieve.
ApprovalMax connects invoice capture, purchasing, checks, approvals and payments with your accounting system. Moss combines AP with wider company spending. ApprovalMax gives finance teams a connected supplier-invoice process and extends that control to customer invoicing.
Capture invoice details automatically, keep the purchase and supporting documents together, and send each decision to the person responsible.

| Invoice capture | ApprovalMax Capture reads supplier invoices automatically, which reduces manual entry. Included in current Xero and QuickBooks Online plans. | Invoice capture with OCR |

Moss AP is the payables module of a modular spend platform. ApprovalMax is finance software covering accounts payable and accounts receivable end to end on Xero, QuickBooks Online and NetSuite.
ApprovalMax gives finance teams a priced Xero or QuickBooks Online subscription for AP automation, with customer-invoice workflows alongside supplier bills. Journals and sales quotes on the relevant plans bring further decisions out of email and into the same platform. Moss prices its subscription, modules and transactions by quote.
ApprovalMax supports routing by attributes such as amount, supplier and department, with stages running in sequence or in parallel. Moss AP documents multi-step approval flows with role-based controls.
A £7,500 consulting bill might need the budget owner and finance director, while a £750 bill follows a shorter route. ApprovalMax uses value, supplier and department rules to send each invoice to the right people.
ApprovalMax Advanced and Premium include a Review step for Xero and QuickBooks Online, so accounting details can be checked before formal approval begins. The Xero offer also includes Editing on Approval, allowing authorised corrections during review. This helps finance resolve coding issues before final sign-off.
ApprovalMax has dedicated products for Xero, QuickBooks Online and NetSuite. Moss supports accounting and ERP integrations including those platforms, with the exact scope depending on the connection.
Where ApprovalMax separates is the breadth of documents it will approve on those ledgers. The Xero product includes sales invoice approval and offers manual journal workflows on relevant plans. The NetSuite product documents sales order, sales invoice and journal approvals alongside purchasing and bills.
Customer invoices and journals also need review. ApprovalMax keeps those decisions with the records on supported plans, so finance can check a discount or month-end adjustment without starting another email chain.
ApprovalMax lets staff raise purchase orders and obtain approval before the supplier receives them, with bill-to-PO matching on Advanced and Premium and three-way matching available for NetSuite. Moss offers procurement functions including purchase requests, orders and budget visibility, and supports two-way and three-way matching.
If an order for 40 monitors arrives short, finance needs to check both the charge and the delivery. Bill-to-PO matching compares the invoice with the order; three-way matching also includes the receipt. ApprovalMax then keeps the explanation and approval of any accepted discrepancy with the bill.
A matched invoice still follows the configured approval and payment rules; matching alone does not release money.
Both read invoices with OCR. ApprovalMax Capture is included from Standard on Xero and QuickBooks Online, so the extraction, the approval and the ledger posting sit in one subscription with a price you can see before you talk to anyone.
Moss pays invoices within its platform, subject to regional terms. ApprovalMax Pay sends approved bills in 35 currencies across 150+ countries in batches of up to 200, with fees posted as separate Xero lines. Available to UK businesses using Xero.
ApprovalMax provides document approval records and audit reporting, with the approval history attached to the accounting record. Moss provides audit trails for invoice review.
ApprovalMax keeps the reviewers, decisions and supporting information with the transaction. Finance can explain an unusual invoice without relying on someone's memory.
Moss prices its packages by quote. ApprovalMax Standard Small starts at £35.83 per organisation per month billed yearly, or £43 billed monthly, excluding tax, with unlimited active approvers at every Xero/QBO size.
Size is set by document volume rather than headcount: Small includes 100 approved documents per month, Medium 300 and Large 500, with annual billing pooling 12 times the monthly allowance. Standard covers multi-step approval rules, bill and purchase-order workflows, accounting sync and ApprovalMax Capture; Advanced and Premium add bill-to-PO matching and budget checking. ApprovalMax for NetSuite is quoted separately.
Moss's paid plans include unlimited users. Its subscription, module and transaction prices require a quote, so the total depends on the AP configuration selected.

For a defined, auditable process across everything your accounting system holds, ApprovalMax covers more than the payables module of a spend platform, and tells you the price up front.
Moss AP is the accounts payable module of Moss, a modular spend platform. It processes supplier invoices with OCR, routes multi-step approvals with role-based controls, documents two-way and three-way matching, and prepares accounting exports, alongside procurement and wider business spending functions.
Yes. ApprovalMax is a direct alternative for invoice and purchase-order approvals on Xero, QuickBooks Online and NetSuite. Its case is strongest when the project also covers journals, sales invoices or sales orders, since ApprovalMax extends the same approval discipline to those documents.
No. Moss is a modular spend platform whose range includes accounts payable and procurement as well as card and spend management. Its wider product range does not mean every customer uses every module, so the AP offering should be assessed on its own terms.
Yes. ApprovalMax's NetSuite product supports three-way matching of bills, purchase orders and receipts. Bill-to-PO matching is available on Advanced and Premium for Xero and QuickBooks Online. Automatic approval of matched bills is a separate capability.
Yes. ApprovalMax lets Xero and QuickBooks Online approvers review and authorise their assigned requests without an accounting-system licence. A department manager who handles a few requests a month can take part in the workflow without a ledger seat or access to the wider accounts.
No. Current ApprovalMax plans for Xero and QuickBooks Online include unlimited active approvers, so adding a reviewer adds no seat charge. Price is set by feature plan, organisation count and approved-document volume: 100 documents a month on Small, 300 on Medium and 500 on Large.
ApprovalMax's Xero and QuickBooks Online plans start at £35.83 per organisation per month billed yearly, excluding tax, with unlimited approvers. Moss does not publicly disclose subscription, module or transaction prices, so any cost comparison needs an actual Moss quote scoped to the same requirement.
ApprovalMax runs multi-step bill, purchase-order and accounting-document approvals across Xero, QuickBooks Online and NetSuite, with unlimited approvers on current Xero and QuickBooks Online plans.
