Well you file a notice of claim and they have 14 days to reply (30 if they are outside BC). If they don't reply you can apply for a default order.
If they reply, its either to:
a. agree to pay the amount
b. oppose all or part of the claim
c. admit all or part of the claim and propose a payment schedule
d. counterclaim
If there is still no agreement after they reply then there is a settlement conference set where the parties will sit at a table with a judge. The judge will say a few words and ask each party to give a brief summary of their case. The judge may then lead both you and the other party into a discussion on what, if anything, you can agree on. If the parties agree on the final result, the judge will make the order. However, the parties may agree on some issues and leave issues in dispute to be resolved at trial. The judge will assess how much time is required for trial... Then the trial date is set.
That's just a super general summary of how the process goes. In reality, it takes a lot of time and there is a lot of procedure and preparation needed. You can technically do the small claims process by yourself but if you get to the settlement conference and/or trial part you might want to have counsel.
Most of what I mentioned here comes from the materials we have at school. You can also check out
Making a Claim Small Claims Procedure Guide - Procedures Guides - Small Claims - Court Services - Ministry of Justice for more info.
I can't tell you whether or not it is advisable or worth your time to go through this process because that depends on the specifics of your case. Maybe if you send a notice of claim they'll just pay up. Its better to talk things over, going to court should be a last resort. I think this should have answered all the questions in your original post too.
