Most disagreements with a contractor are not about bad faith. They are about a fuzzy memory of what was agreed, what was quoted and what was already paid. The defence is a simple, dated record kept while the work happens.
In EMALINO you keep each job with the property it belongs to: the contractor details, the quote, photos of the work in progress and when it is finished, the invoices and the cost. Everything for that piece of work sits together rather than scattered across messages and email.
When a question comes up later, a warranty claim, a snag, a final bill that does not match, you open the job and the answer is already there: what was agreed, what was done, and what it cost, with the photos to back it up.
