Your accounting software should adapt to you, not the other way around.
The 4-4-5 retail calendar is a classic example of where rigid software fails. A simple request, such as "Can I see my revenue in 4-4-5 periods?" can trigger costly custom engineering projects or painful manual spreadsheet work.
So, on day 16 of Vibe Accounting, when a retail customer asked us for this exact format, we didn't see a roadblock - we saw a perfect challenge for our AI agent, Luca.
While our UI is built on a standard calendar, our agent isn't bound by it. We tasked it with building the report, and in just two prompts, it delivered.

The first prompt set up the 4-4-5 structure.
A second quick refinement ensured each period correctly ended on a Sunday.
That's it. No custom code. No support tickets. No messy CSV exports.
The fundamental promise of AI in finance lies in its flexibility. Software no longer needs a button for every possible scenario, but can instead act as an intelligent partner that adapts to how your business actually operates.
