Vend has an awful lot of stupid bugs, and pretty inept front-line support. Even with reproduction steps and screenshots, they don't seem to understand tickets reporting bugs at all. It can take multiple back-and-forths before they escalate it to someone in dev that might try to fix it.
An example they just fixed after I handed them the bug and the fix -- they handled discounts on a purchase (i.e. a coupon, or F&F discount) by adding a special "Discount" product to the sale. In their database, hidden to the store owner, this "Discount" product was flagged as a taxable item with negative value. If someone wanted to buy a $10 item and handed you a $10 coupon in a state with 7% tax, the register would tell the cashier to give the customer $0.70 in change, and take $0.70 out of the month's tax you owe to the state. There were similar glitches in basic, critical calculations in inventory tracking, cost of goods sold, etc. There were oddities like if you used a barcode scanner, and had mis-typed a barcode when adding a product to inventory and lost a digit, the scanner would still pull up the product via the partial match, and it'd also add sales tax to that item even if it was marked as a non-taxable product (i.e. groceries in a state that doesn't tax them). So someone doing inventory could mess up your sales tax collection on that product for the whole year and it might never be noticed.
It's not a solid product, and the only reason we still use it is its integration with our Shopify store to keep the website inventory updated as items sell out in the retail store.
That last line is a serious dealbreaker. We run Lightspeed Pro POS at our two retail locations, and while it is great it still does some things stupid. On the bright side, it does sync with Magento for our website.
I had a similar complaint about Venmo. Yes, it was pretty, but dammit, they should have known to scrub their CSV export for newline characters and commas. There was just a lot of apparent sloppiness to the actual working of things under the hood, even if the front of it was clean and smooth.
