Jobber to Ads: offline conversion mapper

The hard part of reporting closed jobs back to your ad platforms is not the upload. It is that Google, Microsoft and Meta each track a different click id, and none of them can be added after the fact. This is a working reference of the whole loop: a paid invoice in Jobber, matched to the click that started the job, reported to each platform that can actually match it.

Reference tool. It builds the exact payloads each platform expects, using sample data. It is not connected to a live ad account and uploads nothing.

Pick a scenario

Paid invoice number Used as the order id so a conversion is never counted twice.

Paid amount

Currency (ISO 4217)

Google Click ID (gclid) Captured at form submit into a Jobber client custom field.

Microsoft Click ID (msclkid) Bing keys off this, not the gclid.

Meta Click ID (fbclid) Meta composes its fbc value from this plus the click time.

The rule

Report the paid value to each ad platform whose click id was captured at intake, and to no others. A job that came from a Google ad carries a gclid only, so it reports to Google only. A click id cannot be recovered later, so the ones you did not capture at the form are gone for good.

A Fillout form submit creates the Jobber client and stores whatever click ids the URL carried (gclid, msclkid, fbclid) in client custom fields, not tags.
The invoice is marked paid. That event triggers the flow and carries the invoice total.
Find the client to read back the stored click ids.
For each platform with a matching click id, build its offline conversion and send the real revenue. Skip the rest, on purpose.

Out: what each platform receives

What a real setup gets right

Captures every platform's click id at the form, up front. You cannot backfill a msclkid or fbclid onto an old lead, so a form that only grabs the gclid quietly loses Bing and Meta forever.
Triggers on the invoice being paid, not created. The number your ad platforms optimise toward should be real collected revenue, not an amount that was quoted.
Sends the invoice number as the order id. If the paid event ever fires twice, the platform dedupes on that id instead of double counting the job.
Reports to a platform only when it can match. A conversion with no click id and no hashed customer data just fails silently, which is how attribution ends up looking broken.
Keeps the click time separate from the conversion time. Meta's fbc value is built from when the click happened; the conversion value is the invoice, paid later.
