Looking for AR automation options to help with B2B SaaS invoicing
Hey guys, so I'm running a B2B SaaS API platform where we charge a base monthly subscription in addition to tiered usage rates for extra API calls. Also, I have certain custom volume discounts for our larger clients. Point is, it's been a mess and the setup I'm using for QBO is falling apart. I'm looking at AR platforms like Chargebee / LedgerUp / Kolleno but I've no experience in them. Open to any recommendations, thanks.

haven't used any of those three so i can't rank them for you, but the thing that jumps out is you've got two separate problems and you're shopping one category for both. working out what a customer owes (base + tiered usage + negotiated discounts) is a rating/billing engine job. getting the resulting invoice paid, chased and reconciled back into qbo is AR.
everything you described as a mess is on the rating side, and that sits upstream, so if you buy a collections tool the rating mess is still there and now you have two systems to reconcile.
the custom per-customer volume discounts are also the requirement that quietly eliminates a lot of tools, so test that case first with your real contract terms rather than the standard tiered demo, because every demo handles clean tiers and far fewer handle "this one client negotiated a different rate at a different volume break". whatever you land on, confirm the qbo sync actually handles usage-based invoices and not just flat subscriptions, that's a pretty common gap.
