A squiggle on a damp piece of paper
The job is finished. The engineer hands the customer a clipboard with a carbon sheet, the customer scribbles something illegible without reading it, and the sheet goes in the van. Sometimes the customer is out and the sheet is left unsigned. Sometimes it is signed by "the lady next door". Sometimes it gets rained on.
Weeks later, the customer disputes the invoice. They say the work was not finished, or was not what they asked for. The office goes looking for the signed sheet. It is in a box, in the van, or nowhere.
Why paper sign-off fails when you need it
Paper signatures are collected as a formality, so they get treated as one. The customer signs a blank-ish form without a clear summary of what they are agreeing to. There is often no printed name, no time and nothing linking the page to a specific visit.
The sheet also has a long journey before it is filed. Every step, from van to office to scanner to folder, is a chance to lose it. When a dispute arrives, the one document that could settle it is usually the one that went missing.
Some businesses have moved to asking customers to sign on a phone, but through a general form app that stores the signature somewhere separate from the job, which only moves the filing problem.
What weak sign-off costs
| Situation | Result |
|---|---|
| Invoice disputed | No evidence to hand, so you discount or write it off |
| Work scope argued | No record of what the customer agreed on the day |
| Unsigned sheets | Nothing to show the job was accepted |
| Illegible signatures | Cannot tell who signed or whether they could approve it |
| Late filing | Invoices wait for paperwork to arrive |
There is a quieter cost too. When staff know the paperwork is weak, they hesitate to chase unpaid invoices firmly, and money that is owed stays unpaid for longer.
For businesses working for landlords, managing agents or larger companies, the problem is sharper. Their accounts teams often want proof of attendance and sign-off before they release payment, and a scan of a smudged carbon copy with no name on it tends to go back to the bottom of the pile.
How we build it
- Summary first. At the end of the job, the app shows the customer a plain summary on screen: what was done, parts used, time on site, any notes or recommendations, and photos if relevant.
- Signature capture. The customer signs with a finger, types their printed name and, if you need it, their role, such as tenant, site manager or homeowner.
- Context recorded. The app records the date, time, engineer and, if you choose, the location, alongside the signature.
- Customer not available. If nobody is there to sign, the engineer records why, and the app can send the customer a link to review and approve the summary remotely.
- Signed PDF. A PDF of the job sheet with the signature and details is generated and emailed to the customer straight away.
- Filed with the job. The signed record is attached to the job in your system and linked from the invoice in Xero, QuickBooks or whichever package you use.
For work where a formal electronic signature service is required, for example contracts or quotes, we can connect to DocuSign or a similar provider rather than capturing it in the app.
What changes when a dispute arrives
The customer receives a copy of the signed summary before the engineer has left the drive, so there is little room for later confusion about what was agreed. If an invoice is questioned, the office opens the job and the signed record is there, with photos, the time and who signed.
Invoices no longer wait for paperwork to be dropped off. And unsigned jobs are flagged automatically, so they are followed up while the visit is fresh, not months later.
Does this happen in your business?
- Customers sign paper sheets that are often illegible or missing
- You have lost disputes because you could not find the signed sheet
- Jobs are left unsigned when the customer is out
- Signed sheets travel in vans before reaching the office
- Signatures captured on phones are stored away from the job
