Some background info:
I give a free version of DSS (i name it AfterCare) to roughly 90% of customers who pass through our workshop, this "free" version allows them to manually run 3 house-keeping apps but most importantly, it gives a link to our paid for auto-maintenance which completes the housekeeping on a weekly basis.
With that said, it's down to my company to deal with the expiration of any subscription i may offer, i'm unsure how else an expiration could happen. I'm not being frigid here, it’s just you can do, what you want to do, when the subscription ends.
This next bit… I’ve assumed you’re actually enquiring how a subscription can end and what DSS can do about it… tell me to shove whatever up my own arse if incorrect
DSS works on templates and my usage/mileage is to on the final stage of any repair, install our free AfterCare app which acts as a business card from our own perspective. If any customer wanted to automate or schedule-weekly general maintenance, I simply change their template to either “Sub-Std” or “Sub-Std-SSD”. It’s a piece of piss to change the template too, it’s literally a few clicks to change it, I feel somewhat “guilty” in charging customers £40 a year when it takes 5 seconds to make this alteration.
That is until I realise it took far too long to learn how to do this efficiently. It’s been a fuck-load of months since I’ve seen a return on my initial investment from subs alone, but… the feedback, returning customers and referrals we've received because of it, vastly outweighs the lack of updates offered to DSS.
I use the terribly un-sophisticated method of using the calendar in outlook to register when the customer is 10 months into their sub, i then email them at that point, then again when two weeks away, then i change them back to the freebie version (although i haven't had to do this yet) when 370 days or so has passed, if they re-subscribe, i simply re-enter the info into outlook.
You need to realise it is mostly white-label and is complicated to understand from scratch, but customer satisfaction is key and DSS can, used wisely open new doors of revenue.
Hope that helps…
I can walk on water, but I can’t perform miracles.
