Nice, I hope you are spending 1h per month for each customer as well advising them how the can get the most out of your service and/or improve their integration - otherwise it would seem like you are expecting unpaid work from your customers, which is ridiculous.
You hired a house cleaner, you told him everything he needs to know, he did a good job. Next time unfortunately he arrives with broken vacuum cleaner, he has another one, smaller, less powerful takes him longer to do the job but it's still done, not spotless but it's fine, he is a nice guy, has good attitude. Another time and he arrives with faulty steam cleaner, again , work is done but takes longer, not ideal outcome. This is happening again and again, he even asks you sometimes to wiggle the cord, push some buttons and try to troubleshot, you know, improving the vendor and stuff.
I hired a house cleaner. I didn't tell them what to do because figuring that out is their job. They didn't do the things I wanted and they even missed some spots on what they did do. I didn't tell them about that either. It's they're job. So I fired them and switched to another. Repeat. Maybe eventually one of them will figure it out.
