Excel to hotel PMS: a seven-step hotel software migration guide

An Excel hotel reservation spreadsheet can be a starting point for a small team. As more staff edit bookings and maintain separate cash records, moving to a hotel PMS becomes a workflow decision as well as a data task. This guide explains how to prepare the transition without losing track of open accounts.

1. Decide which records are authoritative

A hotel may have several spreadsheets: reception’s booking list, management’s revenue file and a separate cash record. Identify which one is authoritative for each type of information. Copying two contradictory records into new software does not resolve the contradiction.

Assign one person to approve the room list, future reservations, guests currently staying and open accounts. Other staff can propose corrections, but responsibility for the final version should be clear. This is especially useful when several shifts have maintained different copies of a file.

2. Back up and clean the source data

Preserve the original files in a dated folder and work on copies. Limit access to staff involved in the migration. Do not send guest records to an open messaging group simply because that is the quickest way to share a sample.

Standardise room identifiers: “01”, “1” and “Room 1” may all refer to the same physical room. Check day/month ordering in dates, telephone formatting and reservation identifiers. Extra spaces or inconsistent spellings can make duplicate detection harder.

Do not automatically merge two guests because they have the same name. Two stays by the same person may also be separate reservations. Flag uncertain rows for a staff member to resolve instead of guessing.

3. Map spreadsheet columns to the new fields

Ask the supplier for the accepted format and establish which information can be imported and which needs manual entry. “Migration from Excel” does not promise automatic transfer of every historical record. For BirOtel, agree on migration scope and service terms in advance.

Source information	What to verify
Room number and type	A matching room exists in the new system
Arrival and departure	Date format and number of nights are correct
Reservation source	Telephone, direct and other sources stay distinguishable
Charges and payments	The outstanding balance reconciles
Additional services	They remain separate from room charges

Do not invent values that are missing from the source. If the payment method is unknown, recording everything as cash without confirmation would distort the cash report.

4. Test a small, varied sample first

Choose roughly ten reservations covering different situations: future arrivals, an in-house guest, partial payment, a date change and a cancellation. Include an hourly stay if your property uses that workflow.

Check more than whether a booking appears on screen. Nights, charges, payments and balances should agree with the approved source. If the sample fails, correct the mapping rule before processing a larger set. Fixing one rule early is easier than repairing hundreds of inconsistent records later.

5. Reconcile bookings and open accounts

Prepare a cutover checklist with future reservation counts, in-house guests, outstanding balances and deposits received. Put old and new totals side by side. Investigate and approve every difference before declaring the migration complete.

Do not compare reservation revenue directly with money received. A deposit can relate to a future stay, while a payment can settle an earlier debt. Our reservation workflow guide explains why booking, room and payment states should remain separate.

6. Train staff for their actual roles

Reception should practise bookings, arrivals and departures. The person responsible for cash should check partial payments and shift totals. Management should find the reports it needs without someone navigating on its behalf.

Give staff individual accounts with appropriate permissions. Prepare a short handover checklist and agree who corrects wrong dates, room assignments and duplicate records. A general presentation is useful context, but it does not replace hands-on practice for each role.

7. Set a cutover time and a recovery procedure

Choose a relatively quiet operating period. Include changes made since the initial export, then tell the team which system is authoritative for new transactions. Editing the same booking independently in two places can quickly produce different balances.

Review the first shifts closely. Decide who can pause the transition, which backup is available and how new transactions will be preserved if a critical mismatch appears. Keeping the old files is a traceable archive, not a reason to continue two competing live systems.

Review BirOtel for small hotels and prepare an anonymised room-list sample for your demo. Set the final transition date only after checking both the data and staff readiness.
