Setup let me bypass all elements so I posted to payroll - and I think that broke your algorithm because now the (ks-Info-Neutral) div at the top of every panel says: "An error occurred, please try again."
Invoiced a customer, which wasn't easy. Stymied because I didn't specify a tax. Good thing I remembered where to set that constant - had to back out, re-entered Setup then added a Tax Item...which should have worked but didn't - until it occured to me maybe I should give it something called a Parent Group. Boom, but now I notice the tax rate isn't transferring from the Setup pane. That's right, the Invoice displays 0% even though I entered Tax Item in Setup as 3.4%. Oh well, it works - and that concerns me. On to the financial statements. It appears I owe my creditors negative 1 million dollars. Haha so does that mean they owe me? Need some commas in there to separate digits into threes. Nice drilldown on the P&L. Open in Excel link broken. Hiding Help - oh this is wild: Help is a different feature than Help! with an exclamation mark which logs me out and takes me to an unbranded site.
Caveat: I've built some corporate tax software for a US state revenue dept and managed expense+reporting tech evangelism at a corporate card company. That said, my work has been tangential at best to Bionic Books and I'm not a CPA so take my comments with salt.
