Is it normal for a simple repair to turn into a half hour of hunting for info?

I keep a naming system for the PDFs and it has saved me more time than any app ever has. Model number first, then the year, then what the doc actually is. So it reads like WTW6200 - 2012 - wiring. No clever names, no 'misc' folder, nothing that requires me to remember what I meant six months ago. If a file does not fit the pattern it goes in a holding folder I clean out once a month, and anything still in there by then prolly was not worth keeping anyway.

The model variant thing is its own nightmare though. What worked for me was snapping a photo of the full sticker on every machine I service, including the serial number, before I even start the job. Half the time the serial is what the manufacturer's lookup actually wants, not the abbreviated model number printed on the front of the unit. I drop those photos into a folder named by the customer's street. Sounds backwards but when a customer calls back a year later about the same washer, I can pull the exact variant in about thirty seconds instead of guessing between four near-identical models.

For portals, I made a single document, just a plain text file, with every login, portal URL, and one line on what each site is actually good for. Which one has decent service bulletins, which one has the wiring diagrams buried three clicks deep, which one is useless on a phone so do not even try. Ten minutes of maintenace whenever I hit a new site beats re-learning the whole mess every time. I did try one of the paid parts aggregator subscriptions for a year. It was fine for cross-referencing part numbers but the diagrams were often lower quality than the manufacturer's own site, so I dropped it. The free manufacturer lookups plus my own folder beat it, honestly. And I stopped saving service bulletins as PDFs. I just screenshot the relevant page into the customer's folder for that job, because a bulletin saved 'for later' is a bulletin you will never find again.

Honestly the thing that burned me out wasn't the paperwork, it was ordering a part that looked identical and showing up as the wrong revision because they changed something mid production year. Now I won't order anything untill I've got the serial in front of me, learned that the hard way after eating the return shipping twice. Also calling the manufacturer's parts line can actually be faster than thier own website, some of those folks will read you the right diagram number over the phone while the site is still spinning.

The thing that actually changed my days was a cheap magnetic phone mount I stuck inside the washer lid. Sounds dumb but it means I can pull up the diagram or bulletin right at eye level with both hands free, instead of propping the phone on the machine and having it slide off every two minutes. Half my paperwork frustration was really just awkward phone juggling while covered in water. I also started dictating my notes on the drive back instead of typing them at night, so the job notes are done before I even get home. Still fight the portals every week though.

What finally clicked for me was snapping a photo of the part itself before I order anything. Pumps, boards, valves, they almost always have the part number molded or printed right on them, and half the time it's not the number the lookup gives you for the model. Photo of the sticker plus photo of the part has killed almost all my wrong-part orders. The other thing I do is keep one note per brand with the weird stuff I've run into, like where a certain brand hides its filter or which series always has the same leak. Took a year to build but now it's the first thing I open on a job, before any website.

Update: tried the naming thing from the first reply and it actually stuck. Model number first, then the doc type, nothing clever. Also started snapping a photo of the part sticker before ordering, which saved me on a fridge compressor last week when the lookup gave me the wrong revision. The junk drawer folder is officially retired.
