Customer sign-off with no signal in the Field Service app
Last updated 29 October 2026.
The customer signs on the technician’s phone, in a plant room, a basement or on a roof, with no signal. The technician taps Submit and moves on. When the phone syncs, Docable makes the signed PDF from the work order and files it there. Nobody has to come back and tap anything.
This guide follows one document from start to finish: the site visit report for work order 00000046, an annual service of a roof-top solar array for HelioGrid, a sample brand.
Before the visit
- Your administrator has set up the action once. See Set up Docable for the Field Service app.
- The template has a signature block for each signer set to Signed when the document is made. See Set up the template.
- The technician’s phone has synced since the template was made active. Each document’s example comes to the phone with the job; there is nothing to open online first.
1. Open the job and take the photos
Take the job’s photos first. A photo taken before Submit is in the document, even while it is still uploading.

Tap Actions, then Generate Service Document.
2. Choose the document
With no signal, the line at the top reads Offline · the document is made when you’re back online, and the documents for the job are still listed.

Choose the site visit report, then tap Preview and sign.
3. Check the example
The preview is an example made on the phone from the job, marked EXAMPLE. It shows what the document will show: the job’s details, its lines, the photos taken on the job, the counts, and only the sections and results that apply, such as All clear when every item passed. The banner says the document is made from the latest details when the phone is back online.

If the document asks questions, such as a reading or a pass or fail, answer them now. A required one must be answered before Submit.
4. The customer signs
Tap Sign here · Customer. The signature sheet fills the phone, with the name filled in from the work order’s contact. The customer signs with a finger above the line, and taps Save.

If the customer has gone or won’t sign, tap Unable to sign? and choose the reason, with a note if needed. The document prints the reason where the signature would be.
5. The technician signs

Tap Sign here · Technician, sign and tap Save.
6. Submit
Tap Submit. The screen says Saved for later and closes. The request waits on the phone with the job’s other changes.

7. The phone syncs
When the phone has a signal again and syncs, Docable makes the site visit report from the work order as it is then, with the answers, the photos and both signatures, names and dates. The PDF is added to the work order’s Files, and each signature is saved on the work order as a Salesforce Digital Signature.

If the document can’t be made, Salesforce sends the notification A document saved on your phone wasn’t made. Tap it to open the record and make the document again.
Good to know
- The document number and money totals are filled in when the document is made.
- Several documents with one signature need a visit pack, such as the service report and the gas safety record for one boiler visit. See Visit packs.
- No signal works in the Field Service mobile app. The Salesforce mobile app makes documents while connected.
