ERP Consultant for Hotels

Where the ERP sits next to the PMS

A hotel runs on two kinds of process. Guest processes, such as reservations, check-in, room assignment, folios and check-out, belong to the PMS and connected channel, booking and guest tools. Business processes, such as accounting, purchasing, stores, maintenance, payroll and reporting, belong to the ERP. The process map I draw for hotels makes the handover explicit:

• Daily revenue: PMS night audit -> revenue by department, segment and tax -> posted to the ERP ledger -> reconciled to payments by method.
• Receivables: guest ledger stays in the PMS -> city ledger for corporate accounts, travel agents and event clients -> invoices, collections and aging in the ERP.
• Procure-to-pay: department requisition -> approval -> purchase order or market list -> receiving -> main store -> issue to outlet or department -> invoice matching -> payment.
• Maintenance: request from housekeeping or front office -> work order -> parts and contractor costs -> asset history.
• Reporting: PMS statistics such as occupancy and average rate combined with ERP costs -> departmental P&L and owner pack.

Drawing this boundary early avoids two common mistakes: trying to run guest billing in the ERP, and posting every individual folio transaction into the ledger when a daily summary would serve finance better.

Common pain points in hotel back offices

Hotels that ask for help with their back office usually recognize several of these:

• Manual revenue posting: the night audit report is typed into accounting every day, which is slow and introduces errors that surface at month-end.
• City ledger leakage: corporate and event invoices are raised late, disputes are not tracked and old balances sit unresolved.
• F&B cost surprises: purchases are expensed on receipt rather than tracked through stores, so food and beverage cost swings from month to month without explanation.
• Housekeeping supplies untracked: linen, amenities and cleaning supplies are bought frequently but never measured per occupied room.
• Maintenance outside the system: engineering relies on paper or a separate tool, so asset history and maintenance costs are not visible to management.
• Owner reports built by hand: statistics from the PMS and costs from accounting are combined in spreadsheets every month.

Each of these has a process fix and a system fix, and the process fix comes first. For example, F&B cost control depends on a stores discipline the kitchen team accepts, not only on an inventory module. I start with process mapping with finance, F&B, housekeeping and engineering together.

Recommended ERP modules for hotels

For a hotel, the ERP is a back-office platform. The modules I usually include are:

Restaurant and bar outlets inside the hotel normally run on a POS that posts to the PMS or directly to the ERP. Detailed recipe costing and menu analysis may be worth adding for hotels with significant F&B; I cover that in ERP for restaurants. Hotels that are part of a wider portfolio of brands and businesses should also read ERP for hospitality groups.

Designing the PMS to ERP integration

The PMS integration is the heart of a hotel ERP project. Most established PMS products offer some form of export or interface for accounting, but the quality, format and level of detail vary widely, so I always confirm what your specific PMS can provide before designing the flow.

The integration specification I write covers:

• Posting level: usually a daily summary by revenue department, market segment, tax and payment method, rather than individual folio lines.
• Mapping: every PMS transaction code mapped to an ERP account and department, with a rule for new codes.
• Receivables transfer: folios transferred to city ledger arrive in the ERP as customer invoices with references for follow-up.
• Deposits and advance payments: how they are held and released, so the balance sheet stays accurate.
• Statistics: rooms available, rooms sold and guests, so the ERP or BI layer can calculate cost per occupied room and departmental ratios.
• Controls: a daily check that PMS totals and ERP postings agree, with a named owner for exceptions.

POS, spa, banqueting and channel tools may connect through the PMS or directly. I document each path so nothing is posted twice. This specification becomes part of the system integration scope for your implementer.

Hotel ERP implementation checklist

Before a hotel goes live on a new ERP, I make sure the following are complete:

1. A departmental chart of accounts agreed with finance, management and, where relevant, the owner.
2. A tested PMS posting specification with full transaction code mapping.
3. City ledger accounts, credit terms and open balances migrated and reconciled.
4. Approved suppliers, price agreements and approval levels configured.
5. Store locations, par levels and an opening stock count for every store.
6. An asset register for major equipment and a starting preventive maintenance plan.
7. UAT using several real night audit days, a month-end close and a city ledger collection cycle.
8. Training for department heads on requisitions, receiving and approvals, not only for finance.
9. A go-live date chosen around occupancy patterns and events, with support through the first close.

Timing matters more in hotels than in many industries. Going live during a peak period or a major event puts unnecessary strain on teams that are already stretched. I plan cutover and go-live support around the hotel's calendar, and I recommend a review after the first few closes through ERP optimization.
