[Ramp](https://payablesbrief.com/cost/ramp/) lists configurable approval workflows on its Free plan, which works out to $1.60 an invoice, while payment release approvals and advanced approval workflows sit in the Plus block. [BILL](https://payablesbrief.com/cost/bill-com/) Essentials costs $1.64 to $1.70 an invoice with standard approval policies, and custom approval policies start at Corporate, $89 a user a month. [Tipalti](https://payablesbrief.com/cost/tipalti/) lists a $99 a month base fee and charges no per-approver fee. ## How we ranked these Criteria, in priority order: 1. List cost per invoice at 5,000 invoices a month, from each [cost record](https://payablesbrief.com/cost/) under the [pricing methodology](https://payablesbrief.com/methodology/). 2. A base fee only, with no cost per invoice. 3. Four approval controls: routing rules by amount, department, vendor or location; multi-level or parallel approvals; mobile or email approval; and an audit trail of approvals. A vendor needs at least two to be ranked. 4. G2 review count, to break ties. Ramp and Coupa both sell all four controls, and Ramp ranks higher because list cost comes first. Coupa ranks ahead of the other quote only vendors. Airbase, Medius, Corpay, AvidXchange and MineralTree sell fewer than two and are left off. ## What each BILL plan adds All four BILL plans come with standard approval policies and six standard user roles. Team, at $65 a user a month, adds custom user roles. Corporate, at $89, adds custom approval policies and discounts for approver-only users. Enterprise, priced by quote, adds dual control. Essentials, at $49, has none of these. ![Four stacked steps showing BILL plans from Essentials at $49 to Enterprise, each adding approval controls](https://payablesbrief.com/img/invoice-approval-software/bill-approval-control-by-plan.svg) Ramp Plus is $15 a user a month, and Tipalti has no per-user or per-approver fees, so a team with many occasional approvers pays differently at each vendor. At [1,000 invoices a month](https://payablesbrief.com/volume/1000-invoices-a-month/) BILL Essentials costs $1.70 an invoice, and at [25,000 invoices a month](https://payablesbrief.com/volume/25000-invoices-a-month/) it costs $1.64. ## Where approval sits in the AP flow Approval follows [OCR invoice capture](https://payablesbrief.com/guides/ocr-invoice-capture/) and matching, and it is the stage an [invoice approval workflow](https://payablesbrief.com/guides/invoice-approval-workflow/) automates: the invoice reaches the people with authority to pay it, and the system records who signed. All seven vendors here also sell capture and matching, which [invoice automation software](https://payablesbrief.com/best/invoice-automation-software/) ranks on its own order. Each of them has a cost record in the [AP automation software ranking](https://payablesbrief.com/best/ap-automation-software/) too. Purchase requests and purchase orders come earlier in the chain, and [procure-to-pay software](https://payablesbrief.com/best/procure-to-pay-software/) covers them. ## ERP sync after approval An approved invoice posts to the ledger. [NetSuite](https://payablesbrief.com/erp/netsuite/) and [Sage Intacct](https://payablesbrief.com/erp/sage-intacct/) syncs sit on upper plans at Ramp and BILL, and [QuickBooks](https://payablesbrief.com/erp/quickbooks/) syncs on every Ramp plan. ## The ranking, with cost at 5,000 invoices a month ### ![](/logos/ramp.png) 1.
