Check what your booking system can already do before you replace it
The proposal to replace your booking system usually arrives before anyone has checked whether the current one can already do what you need.
The reasons are real. Customers say online booking is confusing. Staff keep double-booking. The proposal promises to fix both, with a migration, training and a two-year term.
Go through the complaints one at a time before you read the proposal. For each, ask the current provider's support, in writing: is this a setting, a feature on a higher plan, or something the system cannot do?
The answers sort themselves quickly. Some complaints turn out to be settings nobody changed when the system was set up. Some are on a plan that costs less than the migration. Some are real limits, and those are the ones a replacement has to solve.
Keeping what you have is a legitimate outcome. It rarely comes from the person who sent the replacement proposal, because that proposal is also their revenue.
You may still replace it. Some systems really have run out of road. If you do, you will walk into the new provider's demo with the specific limits you need solved, and you can ask them to show each one working instead of watching their best three screens.
