Won job → review request → 5-star review
Tuesday at 2 PM, you mark Tom's kitchen faucet install as Won. Tom's a returning customer.
Stella waits 24 hours. Wednesday 2 PM, she fires the personal SMS referencing the faucet install. Tom clicks the link, drops a 5-star review on GBP Wednesday evening: 'Mike was great, fast and clean.' Stella drafts a reply within 2 hours referencing Mike + the cleanliness comment. Posts after a 4-hour auto-approval window.
"Hey Tom — hope the new faucet's working out. If you've got 30 seconds, a quick review on Google goes a long way for a small shop like ours: [link]. Either way, thanks for trusting us with another job."
