Risky partnership with WePay means you might not get paid off invoices

I use FreshBooks for my customer invoicing, expense and bank account reconciliation and enjoy sharing direct access to my account with my tax advisor. There were hiccups in setup as the connection to my credit cards and bank occasionally suffered from a broken link since the company used a third party to facilitate the integrations which made things worse for a while. I stuck around since customer service was trying to help me. The last couple of months have seen the credit card integrations finally working much better in pulling in expenses. Unfortunately, FreshBooks partnered up with WePay at some point and it became extremely difficult to receive payments for any of my larger invoices (above $5k) and I couldn't get clarity on why the payments were being canceled and sent back to my clients. WePay was exceptionally unhelpful, and FreshBooks customer support was not particularly helpful in this case. At this point I'm forced to look for an alternative to FreshBooks - essentially anyone not using WePay.
