ERP or PMS for your holiday park: what do you actually need?

Short answer: a PMS (property management system) runs everything around the stay: bookings, availability, the connection with Booking.com and Airbnb, cleaning, guest messages and the invoice per stay. An ERP (enterprise resource planning) runs the whole company: accounting, purchasing, stock, staff and reporting across several sites. A small holiday park, a glamping site or a group of chalets nearly always has enough with a PMS connected to the accountant's bookkeeping software. An ERP only becomes interesting when you run several parks, your own restaurant, a shop with stock and an in-house finance team.

Anyone looking for holiday park or bungalow park software runs into both words. One vendor calls its package an ERP, another a PMS, and sometimes they mean the same product. Below is what each system does, where they overlap, and how to choose without buying too much.

What a PMS does

A PMS is built around one question: who sleeps in which unit when, and has it been paid? In practice:

• Calendar and availability per unit and per type (chalet for 4, lodge for 6, safari tent).
• Channels: through a channel manager, Booking.com, Airbnb, Expedia and outdoor platforms such as Pitchup or Hipcamp stay up to date automatically, so a unit booked anywhere closes everywhere.
• Your own booking page on your website, commission-free.
• Rules such as fixed changeover days, minimum stay and stop-sell for maintenance.
• Cleaning: a daily overview of departures and arrivals, so the team knows which unit has to be ready first.
• Guest communication: confirmation, arrival information, payment link.
• Invoices per stay, with the right VAT, extras such as linen or final cleaning, and tourist tax shown separately.

What an ERP does

An ERP is built around a different question: how is the company doing? It brings every department into one system:

• Accounting and finance: general ledger, VAT returns, supplier payments, budgets.
• Purchasing and stock: the shop on site, the bar, the restaurant, maintenance supplies.
• Staff: rosters, hours, sometimes payroll.
• Reporting across several sites or companies.

An ERP for leisure often has a reservation module built in. That is useful for a group with ten parks, but for a single park you end up paying for a whole finance department in software you will not use.

Where they overlap: the invoice

The overlap is almost always invoicing. The PMS creates the guest's invoice, because it knows what was booked. The ERP or accounting package needs that invoice for the books. So the real question is not "ERP or PMS" but: how does the invoice get from the PMS into the books without retyping?

A connection solves that. In BedFlow PMS, final invoices and credit notes go automatically to Yuki, Billit, Octopus or ClearFacts, see connecting your accounting. Invoices to companies can go out through Peppol, which has been mandatory between businesses in Belgium since 2026. Your accountant keeps working in their own package; you work in the PMS.

When a PMS is enough

A PMS with an accounting connection is the logical choice when:

• you run one park, or a few sites under the same company;
• you mainly rent out units (chalets, lodges, tiny houses, tents), not hundreds of pitches;
• food and drink is limited or run by someone else with their own till;
• you have an external accountant who works in their own software.

That is the profile of most glamping sites, small holiday parks and B&Bs with a few lodges on the side. What to compare between PMS options is covered in Campsite and holiday park PMS: what to look for.

When to look at an ERP instead

An ERP (or a PMS connected to an existing ERP) is the better choice when:

• you have several parks with a central finance team that reports per site;
• you run your own restaurant, shop or pool with stock and purchasing;
• you have many staff with rosters across departments;
• bookkeeping is done in-house, not by an external accountant.

If in doubt, start from the tasks that take the most time today. If that is retyping bookings, updating channels and planning cleaning, it is work for a PMS. If it is supplier invoices, stock and staff planning, you have an ERP question.

Three questions for every demo

1. What happens to an invoice once it is final? Does it go to your accounting software automatically, and to which one?
2. What do you pay for modules you do not use? With large packages the price often sits in modules for catering, staff or stock.
3. How fast can you go live? A PMS can often be set up in a few days; an ERP implementation is usually a project of months.

Where BedFlow PMS fits

BedFlow PMS is a PMS, not an ERP. It suits small parks, glamping sites and groups of chalets: units grouped by type, changeover days, a housekeeping portal, the channels connected, invoices with tourist tax, and an accounting connection so your accountant does not have to retype anything. If you have hundreds of pitches with seasonal contracts and a barrier, you need specialised campsite software, and we would rather say so up front. What it costs is on the pricing page.
