Why it matters
Small changes can become expensive arguments.
Plumbing jobs change once walls, floors and old pipework are opened up. Customers also ask for upgrades and extra work while you are already on site. ExtraAgree gives each change its own clear approval trail instead of leaving the agreement buried in a conversation or relying on memory.

From request to evidence
Send it the way customers already communicate
Send the approval request by email or prepare it for WhatsApp. The customer opens the link on their phone and does not need an ExtraAgree account.
Keep the exact version they approved
If the scope changes later, ExtraAgree creates a new version. The earlier decision stays attached to the exact wording and price the customer reviewed.
Build a useful job evidence pack
Approved extras can be kept as individual approval records and together in a full-job evidence pack, including approval timestamps and stored version references.
Simple pricing
£19 a month including VAT.
Start with a 14-day free trial. Keep your customers, jobs, extras and approval records together, and cancel from your account whenever you need to.
Questions plumbers may ask
- Does the customer need to download an app?
- No. They open the approval link in their browser and approve or decline without creating an ExtraAgree account.
- Can I send an approval request through WhatsApp?
- Yes. ExtraAgree can prepare the approval message and link for WhatsApp, or you can send the request by email.
- What happens if I change the extra after approval?
- The approved version is preserved. A later revision becomes a new version and needs fresh customer approval, so the original evidence is not silently overwritten.
- Is ExtraAgree an invoicing package?
- No. ExtraAgree focuses on getting extra work agreed and keeping the approval evidence. You can continue using your existing invoicing or accounting software.
