Best AP Automation Software for Hotels and Multi-Property Groups

Updated November 2026

A hotel works like several businesses under one roof: rooms, food and beverage, spa, engineering, housekeeping and events. Each one has its own suppliers and budget holders. A multi-property group repeats that structure at every hotel, often across different owners and brands. Accounts payable has to keep it all straight.

Ottimate is our top pick for multi-property hotel groups. It codes every invoice line to the right property and department, routes approvals to the right department head, and flags price changes and duplicates before payment. BirchStreet is a strong option for groups that want procurement-led purchasing. AvidXchange and Stampli suit groups whose needs are closer to general mid-market AP.

Top AP automation tools for hotels compared

What matters for hotel AP

• Department-level cost attribution: F&B, rooms, engineering and spa costs belong in different places.
• Property-level approvals: general managers and department heads approve their own invoices, but corporate finance sets the rules.
• Portfolio visibility: one view of spend and liabilities across every hotel.
• Scalability: opening or acquiring a property shouldn't mean re-implementing.
• Integration: sync with your accounting system, and fit alongside your PMS and procurement tools.

1. Ottimate

Ottimate is AP automation built for decentralized hospitality operators, and its customers include hotels, resorts and casinos. Its premise is simple: a hotel group isn't a generic business, so it shouldn't run generic AP.

Ottimate captures invoice data with 99.5% header-level and 95% line-item accuracy. It then auto-codes 93.3% of line items, attributing each to a property and department. A banquet produce order and an engineering parts invoice from the same supplier land in different cost centers automatically. Finance gets centralized visibility across the portfolio, while each property keeps location-level control.

• Approval routing by property, department and amount; most customers cut approval time from three days to under one
• Real-time price variance alerts and duplicate detection. Ottimate uncovers around $1.4 million in duplicate invoices a year across its customers.
• PO and receipt matching for properties that use purchase orders
• Statement reconciliation: typical customers reconcile in 3 days, with 86% of lines linked automatically
• Insights in seconds: reports that used to take 11+ hours to compile are available through a dashboard and conversational interface
• Ottimate Concierge, dedicated CSMs and white-glove onboarding, staffed by people with hospitality experience

Considerations: Ottimate is an AP and spend platform, not an eProcurement catalog system, so groups that want catalog-based purchasing may run it alongside a procurement tool. Pricing is quote-based. Invoices Ottimate can't read with confidence are flagged for review rather than posted automatically.

2. BirchStreet

BirchStreet is a procure-to-pay platform widely used by hotel groups. It covers eProcurement, supplier catalogs, receiving and invoice processing, and has added AI-powered AP that matches POs, receiving and invoices at the line level.

Considerations: It's procurement-led. You get the most from it when properties buy through its catalogs, and rollout can be substantial.

3. AvidXchange

AvidXchange automates AP and payments for mid-market companies and runs a large supplier payment network. It has been privately held by TPG and Corpay since October 2025.

Considerations: Its deepest industry focus is real estate and construction. It doesn't natively provide line-item coding by hotel department.

4. Stampli

Stampli centers AP on the invoice, with notes, questions and approvals in one place and AI-suggested coding. It works with many accounting systems.

Considerations: It doesn't natively handle line-item coding or surface the portfolio profitability signals a multi-property CFO needs.

5. Tipalti

Tipalti specializes in supplier onboarding, tax compliance and mass payments across currencies, which is useful for international hotel groups.

Considerations: Domestic groups may not need its global depth, and time to value is longer.

6. BILL

BILL is a simple way for an independent hotel to receive, approve and pay bills.

Considerations: It has no concept of property or department cost centers.

Choosing the right platform for your hotels

Start with structure. If you manage several properties with department heads approving their own invoices, prioritize department-level line-item coding and portfolio visibility; Ottimate is built for that. If your bigger problem is uncontrolled purchasing, a procurement-first system like BirchStreet may come first. A single independent property with low volume can start with BILL.
