Accounts receivable and accounts payable are a nightmare to work with. The AP and AR functions require multiple unintuitive and confusing steps, and it's very difficult for clients to figure them out and remember how to use them correctly. If the setup with AP and AR isn't done right, getting everything corrected can take days after you or the client has started booking transactions. AP aging schedules regularly don't tie to the balance sheet, even when transactions are booked right, and support actually recommend we make adjusting journal entries to fix the problem because it would be too complicated to fix otherwise.
The invoice functionality for A/R is very lacking. Invoices have strict character limitations, making it nearly impossible to enter detailed invoices. Invoices must have a quantity listed for each item, it's impossible to just list a couple items with no quantity. We actually had a potential client who decided against working with our CPA firm (we try to get all of our clients on Accounting CS) because they didn't like the invoice features.
The software is slow and laggy, whether navigating between screens or printing reports. It can take several minutes to push out a standard monthly accounting package consisting of GL, income statement, balance sheet, and bank reconciliation for a medium sized client. Booking transactions is slow and laggy, and it's a huge nuisance if you aren't importing transactions from an Excel spreadsheet or from a Quicken file from a bank website.
If Thomson Reuters could fix the speed issues with this product and fix AP and AR, I think it would be a decent choice for small businesses and accounting firms. Review collected by and hosted on G2.com.
