Everybody quotes mystery-shopping pay as the fee on the job posting. A $17 shop is a $17 shop — until you count what it actually cost to earn it and what you lost doing it slightly wrong.

I know, because this week I made my desk count everything. Not estimates. Dot-to-dot routes, chained the way I actually drove them, with my real gas price — $3.79 a gallon, my real average, not the friendly number.

Here is the full ledger for this season's run:

43 shop visits (31 on the Presto platform alone, 12 across the other companies)

453 miles driven, door to door, route to route

64.4 hours total — 16.2 of them driving, 48.2 on site, writing reports, and answering revisions

18.1 gallons of gas: $68.61 out of pocket

$316.79 in true vehicle cost at the standard 70-cents-a-mile rate

And the pay side, last thirty days on Presto: $72.87 paid across 5 shops, with another $90 accepted and still unpaid — two survey shops at $45 each, sitting through three payroll cycles while I chase down who even owes them.

The number that actually taught me something

$246.92. That's what I lost in 45 days — fourteen shops, completed, driven, reported… and declined.

Not declined because the work wasn't done. Declined on technicalities:

Pump photos that didn't show the full pump and the pump number in frame

A canopy shot framed too tight

A duplicate photo where two different ones were required

Revision requests that landed in my inbox and expired before I answered them

Fourteen shops. The gas was spent. The hours were spent. The pay was zero. A completed shop and a declined shop cost exactly the same to perform — the only difference is whether you followed the photo rules like they were the job itself. Because they are.

The rules I run now

1. The report is the product. The visit is just how you gather the material. Shops don't pay for your presence; they pay for a file that passes review.

2. Read the photo list before you leave the house, and count your captures against it before you leave the lot. A missing shot discovered at the kitchen table is a declined shop.

3. Answer revisions the same day. A revision window is a second chance with an expiration date. Expiring silently is the most expensive habit in this business.

4. Count your real costs or stop calling it income. Gas at your actual price, miles at the standard rate, hours including the report. A shop that pays $15 and costs $11 in driving paid you $4 — and only if it isn't declined.

5. Chain your routes. One loop of eleven stops cost me less fuel per shop than any single round trip. Distance is a choice you make on the map before it's a cost you pay at the pump.

What it's actually for

I'm not writing this to talk anybody out of mystery shopping. The money is real — it lands in PayPal on Mondays and Thursdays when the file is clean, and some of the work (the revealed audits, where they know why you're there) is genuinely good work. I'm writing it because the gap between the posting fee and the bank deposit is where most gig workers quietly go broke: untracked miles, uncounted hours, and declined work they never added up.

I added it up. $246.92 worth of lessons, and every one of them was cheaper than learning it twice.
