When is the least disruptive time to switch booking systems?

J
John S.

Ask a software supplier when you should switch booking systems and the answer is usually now. Ask an operator who has done it badly and the answer is usually not then.

The standard advice is to move in the off-season. That is close to right, and it is right for the wrong reason. Off-season is not a fixed period, it is not quiet in the way people assume, and for a large number of UK sites the months with no guests on the ground are the months when next year's reservations arrive fastest. A touring park with nobody on site in January may still be taking forty bookings a week for the following summer. Moving systems during that is not a quiet changeover.

The useful question is not which month is quietest. It is this:

When is the number of future bookings you must carry across at its lowest, and the rate at which new ones arrive at its slowest?

Those two things rarely peak together, and the gap between them is your window. It differs between a seasonal touring park, a year-round glamping site and a holiday park with a hire fleet, which is why a single recommended month is never much use.

This article sets out how to find your own window, what each of the four realistic windows costs you, how long a switch actually takes, and the circumstances in which waiting for the perfect moment is the more expensive decision.

The usual advice is right about the season and wrong about the reason

"Switch in the off-season" assumes the risk of changing systems comes from having guests on site. It does not, or at least not mainly.

Guests on site create operational load: arrivals, departures, questions, problems. That load is real, but it is largely independent of which software you use. A busy Saturday changeover is demanding whether the arrivals list came out of a new system or an old one.

The risk in a migration comes from somewhere else. It comes from reservations that already exist and have to survive the move intact, and from reservations arriving while the move is in progress. Every future booking is a promise: a specific pitch or unit, specific dates, a price already agreed, an amount already paid. Carry a thousand of those across and the exposure is a thousand promises. Carry eighty across and it is eighty.

Meanwhile, any booking taken during the changeover has to be entered somewhere, and if the two systems are both live it has to be entered correctly in the right one. That is where double bookings and missing deposits come from, far more often than from a busy site.

So the two things that make a switch disruptive are the size of your forward book and the rate at which it is growing. Guests on the ground are a secondary consideration. This is why the answer is different for different businesses, and why it is worth spending an hour with your own numbers rather than accepting a general rule.

The two numbers that decide your window

Both numbers come out of your current system, whatever it is, including a spreadsheet.

Number one: the size of the forward book

Count every confirmed reservation with an arrival date in the future. Break it down by arrival month.

This is the volume of work in the migration itself. It is what has to be exported, mapped, imported, checked and reconciled, and it is what you are exposed to if something goes wrong. A site with 90 future bookings has a manageable afternoon of checking. A site with 900 has a project.

Most seasonal UK sites see this number bottom out somewhere between late September and early November. The current season has finished or nearly finished, so those bookings have converted into completed stays and left the forward book. Next season's bookings have started but are not yet in volume.

Number two: the rate new bookings arrive

Count bookings taken per week for the last twelve months, by the date the booking was made rather than the date of arrival.

This is the number most operators have never looked at, and it is the one that changes the answer. Booking creation for UK outdoor accommodation is heavily front-loaded into the new year. January and February are frequently the two heaviest booking-taking months of the year for summer stays, even though the site itself may be closed and empty.

If your heaviest booking-taking weeks are in January, then January is one of the worst times to change systems, despite being the emptiest month on site. You would be migrating during your commercial peak, just not your operational one.

Reading the two together

Plot both by month and look for the point where the forward book is near its low and the arrival rate has not yet climbed. For a large number of seasonal sites this lands in late September to early November, which is earlier than most operators expect and considerably earlier than the January slot they tend to default to.

For a year-round glamping or lodge business the picture flattens out, and there may be no obvious trough at all. In that case the decision moves to a different basis: pick the period with the lowest occupancy in your own historical data, accept that no window is ideal, and put more weight on running the two systems in parallel, covered below.

If you have never measured how much time your current booking admin consumes, the booking admin cost calculator gives you a baseline before you change anything. That number is also the honest test of whether a switch is worth doing at all this year.

Four windows, and who each one suits

End of season: September to October

The strongest window for most seasonal sites.

The forward book is at or near its annual low. The season's operational data is complete, so you are migrating a finished picture rather than a moving one. Staff who know the booking process are usually still employed and available, which matters more than it sounds: migrating with a team that has just left for the winter means the person who understands your pricing quirks is not there to check them.

Winter maintenance has not yet consumed the owner's attention, and there is enough runway to get the new system genuinely configured before next season's bookings arrive in volume.

The trade-off is that it can feel too soon. You are coming off a demanding season and the instinct is to rest before starting a project. That instinct is reasonable and it is also how sites end up switching in February.

Suits: seasonal touring parks, campsites and holiday parks with an Easter to October operating pattern.

Deep winter: November to January

The most popular window, and more exposed than it looks.

November is generally still good. December and January are where it gets difficult, for the reason set out above: this is when next year's bookings arrive fastest for most sites. Migrating in the second week of January can mean carrying across a forward book that is growing by dozens of reservations a week while you are trying to reconcile it.

There is a second problem specific to this window. If you are switching because your current system's contract renews, the renewal date is often 1 January, which creates pressure to complete the move by a fixed date rather than when the work is genuinely finished. Deadline-driven migrations are where corners get cut.

November is a reasonable second choice. January is usually a worse choice than it appears.

Suits: sites whose booking curve genuinely is flat in winter, and operators who have already completed configuration in the autumn and are only cutting over.

Pre-season: February to March

The hardest window, and a common one.

Easter enquiries are arriving, the forward book is at or near its annual peak, and there is no slack anywhere. Any problem that emerges is a live problem affecting real guests with imminent arrival dates. Staff are being recruited and trained, often on the very system you are in the middle of replacing.

Sites end up here not by choice but by drift: the decision was made in October, the supplier conversations took until December, and the work started in February. The way to avoid this window is to start earlier than feels necessary, not to work faster once you are in it.

Suits: almost nobody by design. If you find yourself here, consider deferring to the following September rather than pushing through, unless one of the conditions in the section below applies.

Mid-season: April to August

Only when the current system is actively failing.

Migrating during trading is genuinely difficult and should not be done for incremental gain. It is the right call in a narrow set of circumstances, covered next.

Suits: sites in active failure, and small operations with low booking volumes where the whole forward book is small enough to move in a day.

How long a switch actually takes

Timing advice is useless without a realistic duration, because the question is not only when to start but how much runway to leave.

For a single independent site, a well-run change of booking system takes four to eight weeks from decision to running live, assuming the operator is engaged and the data is in reasonable order. It is not a weekend, and any supplier suggesting otherwise is describing account creation rather than migration.

The phases:

  • Selection and decision. Two to six weeks, depending on how many suppliers you assess and how quickly demonstrations can be arranged. Frequently the longest phase and the easiest to underestimate.
  • Data extraction and cleaning. One to two weeks. Getting your existing bookings, guests and prices out in a usable format, then correcting what is wrong before it moves.
  • Configuration. One to three weeks. Accommodation types, pitch or unit records, seasons, rates, stay rules, deposit policy, extras, user accounts.
  • Import and reconciliation. A few days to a week. Bringing bookings across and checking them against the source.
  • Parallel running and cutover. One to two weeks. Both systems available, then a defined switch.

The two phases operators underestimate

Pricing configuration. This is consistently the longest and least anticipated part. Rebuilding a season of rates, minimum stays, occupancy rules and package structures in a new system is detailed work, and it is the part where errors are most expensive, because a wrong rate sells at a wrong price to a real guest. Allow more time than the supplier's estimate, and insist on being able to preview rates against real dates before anything goes live.

Reconciling future bookings. Importing a booking is quick. Confirming that all 340 of them arrived with the correct unit, dates, total, amount paid and balance is not. Budget real hours for a line-by-line check on anything with money attached, and check the payment figures first, since those are what guests notice.

The booking-system migration checklist breaks these phases into 62 specific checks. If your bookings currently live in a spreadsheet, moving campsite bookings from a spreadsheet covers the extraction and mapping problems particular to that starting point.

Running both systems at once

The single most effective way to reduce migration risk is to overlap the two systems deliberately rather than switch on a date.

A workable pattern:

  1. Configure the new system fully while the old one continues to run everything.
  2. Import the forward book and reconcile it, with the old system still authoritative.
  3. Pick a cutover moment for new bookings only. From that point, every new reservation goes into the new system. The old one stays available, read-only in practice, for reference.
  4. Keep the old system accessible for at least one full booking cycle, and ideally until the last migrated reservation has stayed and departed.
  5. Cancel the old subscription only after that.

The cost of an extra month or two of overlapping subscriptions is small against the cost of discovering in March that something did not come across. Treat it as insurance rather than waste.

Two practical points. Decide explicitly who is allowed to enter bookings where during the overlap, and make sure every member of staff knows, because the majority of migration double bookings happen in this window. And confirm before you cancel anything what you can export from the old system and in what format, since some suppliers make historical data awkward or chargeable to retrieve on the way out.

When you should not wait for the ideal window

Waiting has a cost, and sometimes it is the higher one. Switch as soon as you practically can, whatever the month, if any of these are true:

  • The current system is causing guest-visible failures. Double bookings, incorrect prices shown to guests, payments not recorded against the right reservation, confirmations not sent. Every week of delay is more affected guests.
  • You are losing bookings you can identify. An abandoned checkout, a mobile journey guests cannot complete, an availability search that returns nothing when you have space. This is measurable revenue, not inconvenience. The direct booking website audit will tell you whether this applies to you.
  • The supplier is withdrawing the product or support. A forced end date removes the choice, and moving on your own schedule beats moving on theirs.
  • Your renewal carries a long tie-in. Signing another multi-year term to avoid a short-term disruption is usually the more expensive decision. Check what the next term commits you to before deciding to defer.
  • The forward book is small. A site with 40 or 50 future bookings can move at almost any point in the year. The ideal-window question mostly matters at volume.

Conversely, do not switch during the season for a better interface, marginally better pricing or a feature you would like to have. Those are September reasons.

A worked example: a 60-pitch touring park

A touring park open from mid-March to the end of October, taking roughly 1,400 bookings a year, currently running an older system it has outgrown.

The forward book by month:

Month Future bookings held July 780 September 310 October 95 December 240 February 690 April 810

Bookings taken per week, twelve-month average of 27:

Period Bookings taken per week October 12 November 18 January 46 February 41 April 33

October is the clear answer: the forward book is at 95, its annual low, and the arrival rate is at 12 a week, its annual low. Both numbers bottom out together.

January looks superficially attractive because the site is closed, but the forward book has more than doubled to 240 and bookings are arriving nearly four times faster. The same migration in January means checking 240 reservations while 46 more arrive each week, with staff who finished in October and have not yet returned.

The practical plan for this park: start supplier conversations in August, decide by mid-September, configure through October, import and reconcile in early November, run parallel through November, and take all new bookings in the new system from the start of December, comfortably ahead of the January rush. The old system stays accessible until the last migrated booking departs the following October.

What to ask a supplier about timing

Timing is a fair subject for a demonstration, and the answers tell you a good deal about how the supplier works.

  • How long does a site of our size typically take from signing to live, and what does that estimate assume about us?
  • What exactly do you need from us, at what points, and how many of our hours does that represent?
  • Who does the data import, you or us? What format do you need, and what happens to records that fail to import?
  • Can we run both systems in parallel, and for how long?
  • Can we configure and check our full rate structure before any of it is visible to guests?
  • What does reconciliation look like, and what report shows us that every future booking arrived correctly?
  • What happens if we discover a problem two weeks after cutover?
  • Is migration help included in the price, or quoted separately?

That last question is worth asking of everyone on your shortlist. Migration and onboarding are sometimes a separate chargeable line, which changes the comparison, and the campsite booking system cost guide sets out where those costs tend to sit.

For structuring the wider decision rather than just its timing, use the campsite booking system selection guide or the holiday park software buyer's guide.

The decision in one page

  • The month matters less than the shape of your own booking curve. Work out your forward book by arrival month and your bookings taken per week, and find where both are low.
  • For most seasonal UK sites that window is late September to early November, not January.
  • January feels quiet on site and is frequently your busiest booking-taking period. Treat it with more caution than the empty pitches suggest.
  • February and March are the hardest window. Sites arrive there by drift rather than by choice, so start earlier than feels necessary.
  • Allow four to eight weeks end to end. Pricing configuration and reconciling future bookings take longer than anyone expects.
  • Overlap the two systems rather than switching on a date, and keep the old one accessible until the last migrated booking has departed.
  • If the current system is failing guests or losing you bookings, the best window is now. The ideal-window question only applies when the current situation is tolerable.

If you are working towards a change this autumn, the booking-system migration checklist is the practical next step. It covers data, configuration, testing, cutover and the post-launch checks, in the order they need doing.

And if Keydesk is on your shortlist, switching to Keydesk explains how we handle migration. Onboarding and help bringing existing and future-dated bookings across are included in the subscription rather than quoted as a separate project, which is worth comparing against whatever else you are considering.

A note from the founder

Accommodation software should be one of the most commercially useful tools in the business.

Too often, it's one of the most tolerated.
