The AGPL is pretty easy to comply with in a commercial context even if you are using it as part of a SaaSS product.
Just either use the code unmodified, or release your modifications to customers, or to the public in general.
Do the businesses buying commercial licenses just not understand the AGPL license? or are their development processes not rigorous enough to ensure compliance? The AGPL includes some easy ways to be forgiven for accidental violations, so that should not be a problem in almost all cases. So only deliberate non-compliance should be an issue.
